ORNAMENTING MACHINE.

Application filed April 21,

This invention relates to machines for reproducing a pattern on the surface of jewelry or on other objects and consists in improvements whereby the construct-ion of such machines is simplified, their functioningrendered more perfect and their output increased.

The illustrative embodiment of the invention is herein in the form of amachine wherein the design presented by a pattern may be reproduced on the surface of an object through the action of a. traveler which is caused to pass relatively over the pattern, the traveler being adapted to respond to varying physical characteristics of the pattern and thereby to actuate a. working tool operatively related to the object so that a predetermined design may be produced on the surface of the object.

While certain features of the invention may be embodied in machines of ditl'erent types and employed for widely different purposes, in the. illustrated embodimentof the invention the working tool is adapted to produce a. design on the surface of an ob ject and its movement is effected through devices controlled electrically by the traveler, and the design may be produced oil-her by engraving or by an indenting action, adjustinents being also provided whereby a so-called brocading effect may be produced at will.

The invention will be best understood by ie "eiit'e to the following description when itllitll in connection with the acconi}mnying illustration of one specific embodiment there of. while its scope will be nu'lre pariicuhirly pointed out in the ZllJl'lCllilPll claims.

Referring to the drawings and to the lilustrative einbodiiuei'it of the invcntimi, we have there shown the latter as applied to a machine adapted to produce a surface ornamentation on an article or object pursuant to a predetermined pattern.

The invention may be embodied in machines for ornanicnting articles of various shapes, sorts and sizes, but the illustrative embodiment thereof is constructed specifically to present to the working tool a work piece in the form of a small cuii' button 15 (Fig. 3), the latter being brought by snitable devices, hereinafter described. beneath the tool carrier 17 and its tool, which latter has imparted to it a reciprocatory movement towards and from the face of the cuff but-ton to produce, efthcr by identation or a cutting Eli) action, as the case may be, the required design.

"vw'hile the machine is in operation the tool is given a relative travel over the face of the work piece until it has traversed substantially its entire surface. This relative traverse may be secured in different ways, but herein the work piece is given a constant rotation while the tool is traversed across its surtace radially from its outer border toward its center or axis ot rotation, the w rking contact of the tool theretore taking place in a spiral path of decreasing radius, the pitch of the spiral depending upon the rate of inward travel of the carrier for the cutting tool.

in the illustrated embodiment of the invention a similar relative traverse is pro vided between, the traveler which represented at 19 and the pattern, which latter is herein in the :i'orni ot a cisclke plaque 21, but which may take various forms or shapes, The plaque is rotated at the same rate as the work object and the traveler is fed across the plaque at a rate proportioned to the increased or decreased size of the pattern relatively to the work object. l-leirin the pattern is larger than the work object, being in the illustrated embodiment of the invention approximately six tPmes the diameter of the cull button, so that the traverse feed of the traveler is greater, and specifically six times greater, than that oi? the working tool.

lieterring: first to the devices for rotating the work and pattern supports and more spe ically to 3 and 6, the machine is provided with the main drive shaft which carries at its rear a driven gear meshing with the driving pinion 27, which latter is driven through any suitable iueanz-i, such as the pulley 29 and belt til. from any :mitable source or power.

'lfhe pattern is here shown supported in the cup-s raped turn-table 33 so as to have its upper face presented to the traveler 19, the turu-table being; li'sedly secured on the upright shatt 35, the latter journaled in the .uue 37 ot the machine. The shaft is driven at the recpiired speed through beveled gears 35,) and ll from the drive she 23. The cult button or other work object is carried by a rotary work support -l3 (F 3 and and, to permit the loading of the one or more work supports cn'iployed, the latter are each in the form of a rotatable sleeve mounted in a head or turret by which they may be brought successively into position beneath the working tool or tools l-l'erein the turret is composed of the drum-like memher or head having the top 47 and bottom a9 and mounted. to be turned about the central upright post 51 secured to the frame at the machine.

The machine be constructed to operea ers ate with a single work tool or with any required number of work tools all working in unison and controlled each by the same pattern. and pattern traveler. Herein there are shown two work units each with a work tool and with duplicate actuating; devices connected to be traversed simultaneously and each operatively related to any one of the four rotary work 'arriers with which the turretis provided. It will be understood, however. that the same principles are applicable to machines provided with a larger number of work units, and in such case suitable modifications will be made in the or rangement oi the turn-tableand the number or its rotary work supports.

Herein, however, to cooperate with the duplicate work tools there are provided :tour rotary supports so distributed in the turntable that, while two of them are presenting their work pieces to the respective work tools, the others may be undergoing loading.

1'0 rotate each work support there provided at the upper end of each sleeve 43 gear 53 which meshes with a central gca the latter secured to the upright shaft 57 journalcd in the post 51. fire shaft 57 rotated by the shaft 23 through beveled gears 59 and (51, the gearing being proportioned so that the speed ott' rotation of each work support is the same as that of the pat tern.

The rotary work supports L3 which are simultaneously and constantly rotated and are journaled in the upper and lower plates l? and 49 of the turret, are each provided with devices adapted to hold the work piece while the latter is under the work tool, but permitting the work piece to be inserted at will and easily withdrawn therefrom. For this purpose there is provided in each rotary support a chuck 63 comprising the sleeve 65 which is split to provide resilient spring fingers which tend to open or spread. apart when unconstrained, the lower end of the sleeve being threaded or otherwise secured to the plunger 67 which is normally depressed by the spring 69, one end of which abuts against the head 71 ot the plunger and the opposite end agaii'ist a wall within the rotary work sup port. "When the plunger is lifted (as shown in Fig. 5) the fingers are projected above the surface of the turret plate d7 and they are of such size and shape as to readily re ceive the cuff button 15. then the spring 69 is permited to depress the plunger to its normal position (as shown in Fi 3), the recess provided by the rotary work support and into which the upper flared end of the fingers are retracted, is of such shape as to contractthe fingers and grip the cufi" button, leaving the working surface thereof projecting just above the upper plate of the turret (as shown in Fig. 3).

lOO

During the operation of the machine the turret is held in fixed position to suitably align the work supports with the working tools by any suitable means such as the spring pressed locating pin 73 which is mounted on the machine frame and engages a recess in the turret 45. After the machine has completed its operation the turret is turned by hand 180, where it is again located or centered by the pin 73, and the finished buttons having been automatically discharged, as hereinafter described, the two empty work supports are then reloaded.

To assist in reloading there are provided the two pivoted levers 75, the inner ends of which are positioned one beneath each one of the two plungers 65 for the empty chucks. Each lever is normally ulled down against the stop pin 77 by a spring 79. To load the chuck the operator presses down on the lever 75, lifting the plunger and projecting and expanding the jaws or fingers of the chuck (as shown in Fig. 3), in which position an unornamented out? button is inserted. The lever being then released, the fingers retract and hold the cufi buttons in position ready for presentation each to its tool, when the turret is again turned.

To provide for the automatic discharge of the button or other work object after the work has been completed and the turret turned, automatic means are preferably provided, herein in the form of a cam formation 81 (Figs. 1 and 5), located on the machine frame and lying within the path of the plunger head 71, so that as the rotary work support travels from its work position to its loading position each plunger rides over the cam and lifts the chuck, automatically releasing the button. To insure its discharge from the chuck when released, there is provided a small ejector pin 83 arranged centrally within the chuck between the spring fingers thereof, such pin being slidably mounted in a tubular support 85 secured to or carried by the plunger 07 and pressed upward by the small internal spring 87 so that the top of the pin presses against the bottom of the cuff button. When the button is inserted in the chuck the pin is depressed against its spring. hen, however, the jaws of the chuck are opened by the lifting of the plunger 67 the spring acts to eject the button from the jaws of the chuck. To automatically discharge the button and clear it from the face of the turn-table means may be provided, such as the plate and chute 89 (F 1), one side 91 of which acts to guide the released and ejected button into the inclined portion of the chute as the turntable completes its movement, the successive buttons being thereby conveyed one by one into the inclined portion of the chute and discharged by gravity into any desired receptacle (not herein shown) beneath the same.

Through the described mechanism it will be observed that the pattern carrier and each one of the rotary work supports are given a constant rotation in operative relation respectively to the traveler 19 and the several tool carriers 17 Referring now to the devices for imparting a transverse feed of the traveler radially across the pattern and a similar feed to each of the work tools across its respective work piece, the traveler and its associated parts are supported by a depending support plate 03 (Figs. 3 and 9) which is secured to a horizontally sliding carriage 95, the latter mounted to slide in guideways formed in the head 97 of the machine. Suitable travel of the carriage is effected by means of the feed screw 99 which engages with the carriage nut 101. Similarly each worl: tool carrier with its associated devices is mounted on a depending supporting plate 103 secured to the carriage 105 to which a transverse feed is imparted by means of the feed screw 107 and the cooperating carriage feed nut 109.

To maintain the proper relation of the feeds, inter-meshing gearing is provided between the two feed screws, such gearing con'iprising the pinion 111 (Fig. 3) on the feed screw 99, the intermediate gc 11S and the intermeshing gear 115 on the ed screw 10?, the position oil. the carriage supports and guide and the position of the gearing being such that, starting with the traveler at the extreme outer edge of the pattern or plaque, the traveler moves radially inward until it reaches the center of the plaque, and at the same time each of the working tools is moving from the extreme outer edge of its respective cuff button, or that portion of it to be ornamented. to the center thereof.

'io eti'ect simultaneous movement of the two carriages the shaft for the feed screw 10 has secured at its outer end the worm gear 117 which meshes with the worm 115) on the worm drive shaft 121. l\lovement is inrparted to the worm drive shaft through the pinion (Figs. 3 and G), the latter meshing with the drive gear 125.

The gear is driven from the main drive gear through intermediate gearing which provides for changes in the rate of feed whereby the traverse of the traveler with relation to its pattern and of each cutting tool with relation to its work obj cct may be varied, and the distance between successive spiral paths of the traveler and the tools be made greater or less according to reqi'iirements and the appearance of the design thereby materially altered. Such variation in the feed may be effected in various ways.

Herein thereqare provided three gears 127,

129' and 131 of different pitch diameter shaped arm 1 11, theilatter having a center The gear coinciding with the shaft 137.

is adjustably secured to the shaft 23 by any suitablemeans, such as a set screw, so as to be capable oi? adjustment-to dill'erent positions longitudinally of the sha ft and to align with any one ot' the gears 127, 129 or 131. By loosening the clamp screw 139 the radial arm 135 may be dropped down to di't terent positions bringing any one ot the gears 127, 129 and 181 into mesh with the gear By this means three different rates oi teed may be provided for the traveler and the work tools for the same speed 01 rotation of theipattern and work supports. Any desired number oi speed changes. however, may be produced by the JZ'U\ i4l()l1 ot' additional change gears.

Any desired provision maybe employed for stopping the machine after a. work piece or set of work pieces has been finished, and for starting it up again after the turntable has been turned to present new work pieces to the tools. Herein we have shoi'vn means for accomplishing this by throwing the carriage teed driving mechanismv into or out of engagement, the pattern carriage and the work supports continuing their rotation between successive stages of operation ofthemachine. There may also be provided, as herein shown, devices for automatically stopping the traveler and work carriages when the traveler and work tools have reached the limits of their working traverse, herein the respective centers of the pattern and work object. In the illustrated embodiment of the invention the machine is such that the feed automatically stops when that stage is reached, permitting the cariii-ages to be quickly returned by manual means to their initial positions and leaving the gearing ready to be started as soon as the turret has been moved to bring a newset 01 work pieces under the work tools.

For this purpose the worm shaft 121 has its rear end journaled in a support 142 (Figs. 1, 3 and 6), swiveled on the upright bracket 143 permitting a slight rocking movement thereot andpermitting the worm 119 to be thrown out of mesh with the worm gear 11.7. The opposite end of the worm shaft.

is journaled in a block 1415 which, during the operation of the machine, is so held down as to cause the engagement of the worm and worm gear by means of a pivot catchfinger 1 17 (Fig. 1) pivoted at 1 1.) and normally dra-wn byuthe spring 151 to'lock the block down in position. Tt'the block is released, however, by the outward movement of the catch, it will be thrown upward by the underlying spring 153 against an abutmt-znt 155 presented by the machine 'frame. The face of the block on opposite sides bear against guiding surfaces on the machine frame.

The upward movement of the shaft, when released by thecatch, discngages theworm gear. To provide means for causing this automatically to take place when the trav elcr and the working tool have reached the centers respectively of the pattern and work object, the catch 147 is controlled. by a lever arm 157 pivoted at/159 on the underside of the machine head, the lever at its front. end having a bent portion 161 slotted to receive the depending lower end otthe catch. The opposite end ot the lever lies within th path of a depending screw 163, which may be adjustably located indifferent positions on the traveler carriage 95. so that when the carriage reaches the end of its feeding movement the lug engages the lever and moves it to throw the catch and release the block 11-5, thus throwing out the :l'eed gearing, this being herein arranged to take place at the timethe traveler reaches the geometrical center of the pattern.

After the feed. has been stopped the carriages may be quickly returned by any suitable meansto their initial positions preparatory to the next. operation, here being herein provided for that purpose the crank handle165 which is connected directly to turn the. fine feed screw 107. A very few turns .01 this crank handle serve to return the two carriages simultaneously to their initial positions. After the two .t'eed car riages have been moved back by the crank handle and the turret. has been turned to present fresh buttons or work objects to the action oi the working tools, the feed ot the carriages is again initiated by throwing the feed worm 119 into mesh avith the worm gear 117, which can be readily done by manually drawing down the feed shaft 121. For that purpose the latter is provided with a manually engageablc. projecting forward end 167. When thus drawn down, the worm is brought again into mesh with the gear, the spring 153 compressed, permittin the latch 1 17 to snap into engagement wit 1 the journal block 1&5 and the trigger lever 157 to besimultaneously drawn back with the latch into suitable position to be engaged 'by the traveler carriage on the completion of its next working movement.

Referring now to the devices for controlling the working movement ot the traveler, the pattern is herein provided with a sur face having a varying contour, the pattern b6l11gPIGSGI1tQCl by successive relatively high ill! iii)

and low portions in contrast these being utilized to impart a rising and falling movement to the traveler 19, which is kept in contact with the pattern face as the combined rotary movement oi? the pattern and the radial feeding movement of the traveler cooperate to cause a spiral trav se ot the traveler over the face of the pattern, this in turn effecting a rising and falling movement of the traveler corresponding to the successive relative elevations and depresions ot' the pattern. This rising and falling movement is herein availed of to control the operation of the working tool as a like relative travel of the latter over the work object simultaneously takes place.

The varying contour may be presented either by a design created in relief on the one hand or by incision or int-aglio on the other hand, or pattern characteristics other than those of varying contour may be availed of to secure the necessary movement of the traveler. Certain features of the invention more broadly considered, moreover. may be usefully applied to machines wherein the traveler executes no reciprocatory movement, but variations in other physical characteristics may be relied upon to cause the traveler to produce the required action of the working tool.

In the illustrated form of machine the relative travel oi the traveler over the pattern. utilized to move the working tool iirst toward the work object and then away from the latter as successive portions of the pattern are encountered by the traveler. This may be accomplished in various ways, but in the illustrated embodiment of the invention the rising and falling movement of the traveler is utilized to control electrical circuits which cause the actuation of electric dc for the working tool, the latter also in tne specific form of the invention shown being positively moved first in one direction by such electric devices and then positively in the opposite direction also by elec tric devices, this being in response to opposite movements of the traveler. Many of the features of the invention may be utilized with tool actuating devices of other types, but in. the spec ic eml'iodiment illustrated this arrangemeiu of the traveler not only avoids the necessity of using the surface of the pattern as an electric contact. thereby avoiding sparking at the pattern and burning and disfiguring the same, but permits the use of positive electrical actuation of the working tool in both opposite di rections. increasing the quickness of its re sponse to the movement of the traveler, its etiicieney of operation, and in the case 0t engraving work adding to the quality of the design. As will be hereinafter explained, in the case oi indenting work, a superior re sult may often be had by moving the tool towards the work by electrical means and relying on a spring or its equivalent to move. it in the opposite direction.

Referring to the parts associated with the traveler and more particularly to Figs. :3 and S). the traveler is secured to the lower end of an upright reciprocatory contactcarrying rod or pin l'Tl which is mounted to slide in a guide block 173 secured to the depending carriage plate 9?). Near its upper end the rod carries a laterally extending contact member 175 insulated from the rod and out of electrical contact with the machine frame but connected to the conductor 1.77. In the lower position 01" the traveler the member 175 makes contact with the contact pin 179 (Fig. 9), which latte" has electrical connection with the conductor tail. The contact pin 179 is arranged to yield slightly under the downward pressure of the contact member 175 and is also provided with means whereby it may be accurately and nicely adjusted to time the point of initial contact. For this purpose it provided with the enlarged head 183 which is s-lidable within the sleeve 185, the lower end of the contact pin being threaded to receive the adjusting nut- 18? which latter abuts against the lower end of the sleeve. 'ihe spring 189, one end of which abuts against the end of the sleeve and the opposite end against the enlargement 1S3, presses the pin to its uppermost position which is determined by the position of the nut. These contact devices are supported by a bracket 191 carried by the carriage plate 93, there being provided an intermediate insulating sleeve 193 which prevents the grounding 01 the circuit. In timing the contact pin the nut is turned until the contact pin is positioned at the point where initial contact is desired and the nut is then fixed in posi tion by a set screw.

Axially aligned with the upper end of the rod 171 and in coope'ative relation thereto there is provided a second contact pin 19.3 mounted within a sleeve 197 sup-.

ported by the bracket 199 and insulated therefrom by a sleeve 20L the contact pin 19 and its associated parts being in all respects substantially the same as those already described in connection with the contact pin 179. The pin 195 is in electric contact through the adjusting nut 203 with the electric conductor 295. When the traveler moves up under the control of the pattern. contact is made between the pin iand the slide rod and the latter, being grounded through the frame the machine, as is hereinafter described. the conductor 305 is thereby grounded.

When the traveler moves up, therefore. the lower contact and its corresponding circuit are broken and the upper contact and its corresponding circuit are made. VVhe-n loo mounted in the guide suit the character of the work, its

faces.

the traveler moves down the reverse action takes place. The ad ustability of both sets of contacts permits such ad ustment that one circuit may be made at the same time the other is broken, or such adjustment can be had that each circuit is made before the other circuit is broken. The latter adjustment permits the magnetic effect in one set of actuating magnets for the working tool to be built up before the remaining set of actuating magnets is deenergized, so that the tool acts with a quick snap and without any lag which might be otherwise experienced, thereby increasing the responsiveness of the tool.

The traveler rod is normally depressed to a definite lowermost position, which is carefully determined with reference to the pattern holder or the contour of the pattern, by means of the light spring 207 which is confined between an enlargement 209 on the lower endof the contact pin and the lower face" of the guide block 173. To secure a nice adjustment of the lowermost position of the pin, the upper end of the traveler rod is threaded and carries an adjusting nut 211 provided with a set screw or other means to fix it in position, which nut rests against the upper face of the guide block 173 defining the lowermost position of the traveler and limiting its downward. movement.

Referring now to the parts associated with the working tool or tools, and more particularly to Figs. 3, 8 and 11, these parts are substantially duplicated in each tool unit, the illustrated form of machine being provided with two such units respectively, operatively related to the work-piece holders 1 approximately under ln each tool unit the S) is in the form of slide rod 17, slidably block 213, the latter in turn being capable of whatev r up and down movement is required for working on objects of different or varying height by provision of vertical guideways formed in the depending carriage plate 103. This ver tically movable slide 213 provided at its lower end with a depei'idingguide foot 21'? which is located close to the'working tool and may be forked or of any other shapeto function beingto keep the proper working distance between the tool and the work, whether working on curved, flat or irregular sur- The guide foot is normally held down against the work or turntable facecby a spring 219 interposed between the upper end of the slide block and the lower face which appear in Fig. the feed screw 107.

tool carrier 17 (Fig. a vertically movable of therarriage 105, the springexerting a tool. It willbe seen, therefore, that;asthe cutting tool performs its relative traverse over the surface of the work object, the guide foot maintains the same working relation between the tool and such surface, the slide moving up or down by the action of the guide foot and the spring as may be required to conform to variations in the height of the surface of the work object.

The working tool 221, itself may be either a cutting point for engraving or incisive ornamentation, or an indenting point for brocading work, as will be more fully described, the lower end of the tool carrier 17 being arranged, for example, with a tapered tool holding socket so that a variety of different forms of working tools may be used interchangeably.

Referring now to the electrical devices which actuate the work tool under the control of the traveler, the upper end of the tool rod 17 is provided with an armature operatively related to two sets of mag nets, one of which is located. above the armature and acts positively to elevate the tool, and the other of which 927 is below the armature and acts positively to depress the tool.

Devices are also provided for accurately regulating the throw or stroke of the tool carrier as well as its upper and lowermost positions, and also for liniiiting the minimun'i distance between the armature and the poles of each set of magnets so as to prevent either sticking or drag. To this end the upper end of the tool rod is threaded and provided with a member 229 adapted to rest upon the upper face of the slide block and determine the lowermost position of the tool relatively to the slide block and guide foot 217. This adjustment which constitutes one of the preliminary settings of the machine determines the lowermost position of the work tool and therefore the depth of out or indentation, as the case may be. The threaded member may consist of a nut having means, such as; a set screw. to set it in fixed position after the initial adjustnumt has been made, but herein it is shown in the form of a nut having gear teeth formed in its periphery and associated with devices which are capable of effecting, during the operation of the machine, adjustment of thenut and thereby the depth of cut or indentation, as will hereinafter be more fully described.

The length of stroke of the tool .earrer and the uppermost position of the tool. determined by the pos tion of the adjus able member (Figs. 8 and 11) secured to the lower protruding end of the tool rod and adapted to abut against the lower face of the slide plate 213. 'l is held in tired and nic lyadjusted pos. .on by means of theadjusting nut 233 which-enga the lower three. had end of] the tool .rod. In the 22? are carried (Fig. 3) upon a supporting plate 2 9 which is sa-urcd to the slide 2' rl 312 by me: of the set screw 2 :1 passing through a slot in the plate, so that the mag nets are capable of limited up or down adjustment. This permits the magnets to be accurately adjusted after the limiting posh t-ions ot' the tool rod have been determined to secure the required minimum gap between the arn'iature i223 and the poles of the 1na c; nets and prevent the armature from such close working proximity to the magnet poles as to create any tendency to stick or drag.

Sin'iilarly the upper or elevating set of magnets 225 are supported upon a plate xi-l3 secured to the slide rod by the set screw 24:5 passing through a slot in the plate, so that these magnet-s may be similarly adjusted with reference to the extreme upper position o'ltthe armature 223 to provide the required gap.

The rod 17 is prevented from turning by the threaded pin 2% seated in the plate 9t?) and engaging a groove in the rod.

This arrangement of actuating devices for the tool carrier provides for a rapid, quick, snappy action or the tool in both opposite directions and under the precise control of the follower (as will hereafter appear), while the adjustments, particularly in connection with the adjustments for the contacts at the traveler rod, permit the movement of the tool to be nicely predetermined and prevent missing or lag or drag in its responsx The detailed and specific construction of the parts shown for purposes oli' adjustmentand for preventing the sticking of the armature due to contact with or proximity to the magnet poles, are illustrativeonly. and equivalent results within the broad spiritof the invention may be secured by widely different means.

In the case of indenting work, as distinguished from engraving. good results may be had by omitting the lifting magnets 225 and the travelencontrolled contacts and circuits governing the excitation of these magnets and substituting therefor as a lifting agent a lifting spring. Such spring may be used in substitution for the depressing springs 237, shown in Fig. 11, or, the springs 237jbeing omitted, the lifting spring may be elsewhere located with reference to the tool carrier rod. This lifting spring may be relatively weak so as to give only a partial lift without causing the tool actually to clear the surface. The use of such a spring in substitution for the lifting magnets results in very sharp and fine identatiims by the working tool under the control of the traveler and depressing magnets, giving a relatively soft and line but mind for the design appearing in relief.

The mechanism so far described is substantially complete for the purpose ol an en graving or cutting action. Means, however. are additionally employed whereby the action of the working tool may be modified more or loss during the operation of the machine to produce predetermined ornamental effects in certain portions of the pattern, or additional pattern devices may be employed for further modifying the action oi. the tool so that, through electrical devices or otherwise, the effect of suchadditional put-tern devices may be superposed upon the cl'l'ect ot' the main pattern.

The invention broadly as to many of its :leaturcs is susceptible to application to a great variety oi such uses, but for illustrative purposes there is shown applied to the described form of the machine a mechanical attachment to produce the so-callcd ro tting ell'ect, whereby the tool. when used for indenting purposes, may be given a series ot rapid movements in those parts of the work which correspond to the depressed portions or the pat-tern, thereby imparting to the design a background composed of dots or lines, and such dots or lines may be, according to the method of control, arranged in a variety of designs, as, for example, in a radial or dial form or in a staggered, inatted or overlapping form.

In the form of the invent-ion illustrated .in Figs. 1 to inclusive, this so-called rosetting efiect isproduced by rapidly making and breaking the circuit for the magnets acting to depress the working tool during the time the traveler is in the depressed portions of the plaque, in which position it acts to close the circuit through those magnets. This results in giving an initial downward impulse to the indenting tool when the traveler first moves down and this is followed by a succession of rapid relaxations and pulls as the circuit is rapidly made and broken while the traveler remains depressed.

In connection with Fig. 16, I have disclosed a method by which the rosetting effect may be effectively produced without the necessity of a special circuit breaking attachment.

Referring to 'Figs. 1, 3, 6 and 7 and more specifically to Fig. 7, which illustrates the mechanical resetting attachment, the circuit 247. is caused to pass through contact devices controlled by a rosetting wheel 249 by which it is capable of being rapidly interrupted. The conductor 247 is herein shown connected to a yieldable contact pin 251 similar in its general construction and as to its associated parts with the contact pins 179 and 195 shown in Fig. 9. This contact is in operative relation to a second contact pin 253, the inner end of the latter being adapted to bear against the periphery of the rosetting circuit interrupting wheel 249. The pin 253 is slidably mounted in a cylindrical casing 255, the latter supported by the bracket 257, which bracket is secured to the frame of the machine but insulated therefrom by the strip of insulating material 259 (Fig. 6). A spring 261 within the barrel forces the head of the contact pin 258 against the periphery of the rosetting wheel, a stop pin 263 being provided to limit the movement thereof.

The bracket 257 is connected to the conductor 181 so that when the two contact pins are separated the tool depressing circuit is opened at that point. The rosetting wheel 249 has a toothed periphery so that when the wheel is rotated the pin 253 is rapidly reciprocated and the circuit given a serious of rapid makes and breaks. This causes successive relaxations in the impulses imparted to the tool when the traveler is depressed and the character of these impulses and the appearance of the background produced in the design thereby may be widely varied. by altering the pitch and shape of the teeth on the wheel 249, as well as by varying the speed of rotation with relation to the rotation of the pattern carrier. To turn the rosetting wheel the latter is secured to but insulated from an upright shaft 265 carrying the gear 267, the latter meshing with the pinion 269 which is driven in turn by a gear 271 secured to the upright shaft for the pattern carrier.

To permit any desired variation in the relative speed of rotation of the rosetting wheel the shaft for the pinion 269 is carried by a bracket 273 (FM. 7) adjustably secured to the frame of the machine by a set screw 275 passing through a slot in the bracket. By removing the rosetting wheel from itsshaft, the gear-267= mayalso be removed and replaced by a gearof different size and the bracket-then adjustably shiftedto bring the pinion 269 into mesh withboth-t'he gear substituted for the gear 267and withthe pattern shaft gear 271.

By providing for-the rate of'rotatiomof the toothed Wheel similar to or an even or, bychanging the gearing ratio, it (may be madetohappear' in a staggered or. over- *ated bythe main pattern. 'tlVQ-CilSQtlllS iscarried out by means act lapping form, or spiral effects may be obtamed.

The control of the working tool through the movement of the traveler when the machine .is employed as a brocading machine with an indenting tool and with the rosetting attachment described will be evident from the diagrammatic representation in Fig. 2. One terminal of the upper or elevating set of lifting magnets 225 istherc shown as connected to the battery 277, the remaining terminal to the battery being grounded at 279 to the frame of the machine. The traveler rod 171 is also grounded at 281 to the frame of the machine so that as the traveler moves up the magnet circuit is closed through contacts 171 and 195, energizing the magnets and elevating the tool.

)n the other hand. one terminal of the depressing magnets 227 is connected through the conductor 2d7'and battery 2&8 with the resetting contact 251, the remaining terminal being connected through'theconductor 177 with the contact 175 at'the traveler. The remaining contact 179 there-at is connected to the contact 253 at the rosetting wheel. When the traveler is depressed. therefore, the depressing magnet circuit is closed at the traveler and remains closed at that point so long as the traveler is depressed, the magnet circuit, however, a whole being ulti matcly broken and made by a series of rapid intermrptions through the action of theresetting wheel 249, thus producing on the work object a series of fine indentations during such times as the traveler remains depressed.

To protect the various contacts against damage from arcing, condensers 283 and 285 are preferably employed. lVhen the machine is to be employed as an engraving machine the resetting attachment may be omitted and the depressing magnet circuit uninterrupted except at the traveler control contacts 175 and 179.

Referring now to devices which may be utilized to superpose on the design produced by the mainpattern, also design effects controlled by supplemental or secondary patterns, there is herein shown. as one illustrative embodiment thereof a supplemental pattern carrier289 (Fig. 1) which may be utilized to modify the action of the workingtool while the latter-is being actultn the illustraing-to varythepermissible deptlrto which the tool may-move when it is being impelled toward the work'and 'suehmeans are shown in connection with theresetting attaclnnent so that it isutilized "to 'm'odify tlie rosetting 'ellect, thereby 's'ecuring a supplemental de- -'sign through the eitect' of-a mIere or less IOU shaded background. The invention in its broad aspect, however, may be carried outby modifying the action of the cutting tool in other ways and by a modified action of the cutting tool without reference to the rosetting attachnmnt.

in the specific term ol the invention herein shown the supplen'iental pattern carrier 2% carries a plaque which is rotated by means of a gear 291 n'ieshing with an intern'iediate pinion 393 driven 'l'roin the pattern shal't gear 271. The plaque is rotated thereby at the same rate of speed as the main pattern and in the same direction but in operative relation to a supplemental traveler 295 (see Fig. which is supported to move with the pattern teed carriage 95. The secondary pattern is herein provided with a varying contour. the successive elevations and de pressions of which are arranged with ret'crence to some predetermined design, such contour variations. however, occurring only in those portions of the secondary plaque which are brought under its traveler at the same time that the depressions in the main pattern are brought under the main traveler. The secondary traveler 295 is mounted upon a vertically movable slide rod 297 (Fig. to) slidably mounted in the-guide block 301 carried by the depending plate secured to the main :leed carriage 95. the lowermost or initial position of the secondary traveler bein;- accurately determined and adjusted by the threaded nut 305 at the upper end of the slide rod 297. The secondary traveler rod :arries in insulated relation thereto the laterally extending contact arm 30? adapted to engage with the yieldable contact pin 30$) when the traveler is lifted by its pattern, the contact 307 being connected to the conductor 3H and the contact pin 309 to the conductor 113. The yieldable contact pin 3U?) and its associated parts are of substantially the same construction as those shown in connection with the contact pin 179 in Fig. 9.

hen the machine is in operation and the supplemental traveler 295 is raised and low ercd by engagement with successive elevalions and depressions in the secondary pattern, the contacts 307 and 309 are successively brought together and separated making and breaking the circuit containing conduc tors 311 and 313. Referring to the diagram in Sig. 2. it will be seen that these conductors are connected to opposite terminals ot' the magnet 315 and battery 317, or other source of current being provided, and preferably a condenser 31.9 in shunt to the contacts 307 and 2:309, so that as the de scribed action takes place the magi'iet 315 is alternately energized andde-energized.

Reterring to Figs. 8, '12 and 13. the ett'ect of this action upon the cutting tool will now be explained. The magnet 3.1.5 mounted upon a preferably non-magnetic bracket 321 is secured to the front of the slide block 213 and is o 'ieratively related to an arma ture 323 which depends from the under face ot asmall gear 552-). The 32.) meshes with the teeth of the threaded nut 229 and is capable oi limited movement through the provision of the pin 32? located in the bracket 321 and works .in the slot 329 in the gear. The gear is held in a normal po sition by means of the spring 331 which holds it to the limited position permitted by the slot, and in this position it holds the toothed threaded nut 22%) at the point where it provides the normal working depth for the working stroke of the tool. When the magnet 3t is energized, however, it attracts the armature 6223 and moves the gear to the i urthermost position permitted by the pin and slot, and by so doing turns the ad usting nut so as to slightly increase the depth of the working stroke of the tool. The pin and slot are so located as to prevent actual contact with the pole of the magnet and the latter is preferably secured to an L shaped piece 33 of magnetic material, the opposite end of which terminates adjacent the armature so as to increase the elliciency oi the magnetic circuit. The result is that, as the secondary follower rises and "falls, and the magnet 2315 is energized and deenergizcd, a back and 'l'orth annular movement of the gear 325 and the adjusting nut 229 is eli'ected and variation in the depth of the working tool stroke follows which results in changing the appearance of the resetting, or of the background, it employed withoutlhe resetting attachment, such variation following the predetermined design afliorded by the secondary pattern. The secondary pattern may act through a suitable relation of the magnet 315.- and gear 325,1nomentarily to decrease the depth ol the working stroke of the tool or, as shown in the drawings, serve to increase the depth of such working stroke.

it may be observed that by adjusting the contacts at the main traveler, the contacts at both top and bottom may be prolonged or shortened to any desired extent so as to alter somewhat the action of the tool and the appearance of the design where the same pattern is utilized.

It will be observed that the use of elec tro-magnels for positively imparting opposite movements to the tool carrier provides for an increasing pull or impulse toward the end of the stroke, thereby increasing the rapidity and responsiveness of the tool to the traveler.

In Figs. leland i? there is shown a modilied t'orm of contact mechanism controlled by the movement of the traveler, the contacts being carried and supported by a device independent of the traveler and actuated merely by traveler movement. This l t and 1 3, the contact t l by enl, Y ineiins oi u spring 3%9 secured to a projection $351 attached to the lever on.

l/Vhen the travele' inoves upward it can gages the projecting portion 343 oi? toe lever 34:5 and imparts; a clockwise swinging; movement of the latter, bringing the pin 35? into engagement with the contact- 361 and withdrawing the pin 355 from engrzuren'icnt with the contact 2359, thereby grounding the circuit 205 and breaking the circuits 181 and 177. The further upward movement of the traveler causes a movement of the entire slide to the right, as viewed. in Fig. 1-l-. When the treveler desconde the spring! 22 :9 moves the lever in the opposite direction. separating the contacts 361 and mi causing engagement between contacts r and 359, the de 367 continuing thercater to move in the opposite direction until brought to rest by the adjustable stop pin 369. This stop pin may be so adjusted as J iii to leave any desired lost motion between the collar 34.51. and lever portion 3&3, pcvuuttin n therefore the coi'itacts 355 and 3:79 to be separated immediately on the con z'ilCi'lCS- I ('1:
