To all whomt may concern:

Be it known that I, FRANK L. HARMON, a citizen of the United States, residing 'at Beverly, in the county of Essex and State of Massaclnisetts,'have invented certain Improvements in or Relating to Button-Attaching and Fastener-Setting Machines, of whichithe followingA description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This'invention, in its more particular aspect, 'relates to machines for attaching buttons to stock material'such, for example, as the button flies of boots and shoes, and particularly to machines for attaching the buttons by means of metallic fasteners such as Staples or the like. It will be apparent, however, from a consideration of the construction and mode of operation of the illustrative machine that, as far as many of the various features of the invention are concerned, it is 'immaterial what may be the form or ultimate use or purpose of the fasteners or the buttons, orthe character of the work which is operated upon.

An important object of the invention is to provide in la machine for'attaching buttons by staples an Organization by which the button may be presented with its eye vsubstantially parallel with the 'work and the staple maybe driven with one leg-'inside the button eye andthe other leg outside of` it. To this Aend an important feature'of the invention consists in means for presenting in attaching position abutton with its eye substantially parallel with the work, and means for driving a Staple with one leg of the staple relatively yclose to the portion of the button eye which is outside of the staple. In this organization the driver is constructed and arranged to enter the button eye with its outer edge close to the portion of the button eye which is outside the Staple. This driver constitutesanother feature of the invention and as herein sho-wn is formed with a projection Vwhich enters the button eye and is of suiiicient width to force a portion of the head of the Staple into close engagement with the work while leaving enough space between it and the portion of the button eye which is within the Staple to receive the part of the staple head which betweenl that portion of thebutton eye andthe 'driver proj ection. An important advantage of'this organization'is that it obviates the danger of clamping the button eye close to one of the legs of the staple and between the head of the staple and the Stock, a dilfculty which has heretofore been experienced in machines of this type. Afurther advantageis that a driver constructed and operating as above indicated may be utilized in feeding the Stock while its projection which enters the button eye is in engagement with the driven staple. The driver' isprefcrably formed to engage Substantially the entire'head vportion of the Staple and is shown assh'aped to correspond with thev shape of the novel staple illustrated in the drawings which forms the subject-matter of another applicationQSerial No. 834,914, filed April 28, 1914.

Further features of the invention are to be recognized in novel and improved mechanism through the operation of which, in the illustrated embodiment, a Vfastener is taken by a driving member from theend of a raceway or like Supplying means and by one continuous Ymovement is advanced through J[he eye of'a button at the end ofa button raceway and into the work. In` the construction herein Shown this `v`mechanism comprises a pivoted lever and a fastener inserting or driving member carried bv the lever and cooperating with a suitable anvil to set the fastener in the work.

Other features 'are to be recognized, broadly, in novel and improved mechanism for feeding the work, comprising, in the preferred embodiment, means 'for effecting an additional feeding movement, preferably in a straight path, of the fastener securing or inserting means. In the illustrated machine both the driving member and the cooperating anvil are movable to feed thework subsequent to the driving movement of Said member. To this end, the anvil iS mounted .upon a movable Slide to which is pivoted the lever which'carries the driving member, and the lever is operated to insert the fastener and clench it upon the anvil,`after which the slide is moved to carry both the'driving member and the anvil a Suiicientdistance to bring the work into position to receive the next operation. rl`he driving member and the anvil are then separated and returned to their first positions.

The invention includes also, as features of the work feeding mechanism, novelmeans for relieving the pressure upon the work of the fastener inserting and securing instrumentalities during the feeding movement, so as to avoid undue wear of the mechanism, and novel means whereby adjustment may be e'ected to secure variations in the extent of the feeding movement of the work.

A further feature of the invention consists in means for controlling the position of the work between and preferably during the feeding movements. The preferred construction shown comprises mechanism for subjecting the work to a continuous yielding pressure, and includes a yielding presser member for engaging the work upon the same side of the anvil and a cooperating work positioning member for engaging the opposite side of the work, the yielding member being movable to permit the work to be inserted in the machine` and adjusted in the desired position upon the anvil.

Further features of the invention reside in a novel construction and arrangement for effecting said cooperative relation between the driving member and the means for presenting the fasteners and the buttons as to permit a fastener to be driven and a button to be attached to the work under an impulse of the driving member and to facilitate the presentation of the buttons and the fasteners in succession in cordination with the movements of the driving member.

The above and other features of the invention, including certain details of construction and combinations of parts, will now be described with reference to the accompanying drawings and pointed out in the claims.

Fig. l0 illustrates the manner of setting the staples in the work. Y

The machine receives its operative movements from a pulley 2, which is to be driven by a suitable belt, not shown, and is mounted loosely upon a shaft t supported for rotation in bearings formed in upright eXtensions of the base 6. The pulley is to be operatively connected with the shaft byy any Y suitable form of clutch, preferably a Horton clutch, which includes a dog 8 normally in contact with a cushion spring l0 on the end of a clutch actuating lever l2 in position to release the clutch and permit the pulley to rotate idly on the shaft. The lever 12 has a connection le leading toa suitable treadle, and is held normally7 by a spring 16 in the position shown in Fig. l. W'ith this arrangement, movement imparted to the lever l2 from its treadle serves to release the dog 8 and effect the setting of the clutch, thereby causing the machine to operate during each complete revolution of the shaft l to attach a button to the work and advance the work into position for the next button attaching operation, as will be subsequently explained. As long as the treadle is depressed the machine will continue to operate, attaching the buttons in succession at equally spaced intervals, and when the treadle is released the button attaching instrumentalities will come to rest in the positions in which they are shown in Figs. l and 2.

Connected with the pulley 2 by a belt 18 is a pulley 20 keyed to a shaft 22 from which rotation is imparted to the conveyers for transferring the buttons and Vthe staples from their hoppers to the respective raceways. Secured to the opposite end of the shaft 22 is a crank disk 24 provided with an adjustable crank pin 26 from which Ais operated a pitman 28 connected pivotally to a block 30 whichv has a circular bearing portion mounted rotatably upon a sleeve member 32 keyed in turn to a second sleeve member 34 which has a bearing in the side of the staple receptacle or hopperl 36 and carries at one end the staple conveyer 38. rlhe block 3() carries a spring held pawl e() which coperates with ratchet teeth 42 upon the member 32, as shown in Fig. 3, so as to impart to the conveyer 38 a limited forward movement lof rotationat each forward throw of the pitman 28. Within the sleeve.

34 is a shaft lwhich has a squared end portion fitting in a complementary recess in the side of the rotatable button conveyer 46. The shaft 44 is rotatable independently of the sleeve 34, and the means for operating this shaft includes a pawl and ratchet mechanism comprising a ratchet wheel 48 keyed to the shaft and a spring held pawl 50 carried by a block 52 similar to the block 30 and having pivotally connected thereto a link 54 which is slotted to provide a slideway for a block 56 pivotally mounted upon a block 58 secured to the pitman 28. With this arrangement each forward throw of the pitman will serve to impart movement first to the staple conveyer 38, and subsequently, when the block 56 arrives at the end of the slideway in the link 54, to both the conveyers 88 and 46 together, bringing them simultaneously into position to deliver their articles to the respective raceways. The lost motion connection between the pitman 28 and the link 54 is provided for the reason that the number of staple carrying arms on the conveyer 38 is less than that of the button receiving recesses in the conveyer 46, as shown in Fig. 4, and for the same reason the number of ratchet teeth 42 is proportionately less than the number of teeth on the wheel 48. Similarly, reverse movement of the pitman 28 serves to retract first the block 30 and then simultaneously therewith the block 52, so yas to bring the respective pawls into position to engage the teeth next in order in the series. In order to prevent overrunning of the two conveyers, the sleeve 32 is formed with a friction wheel 60, and the shaft 44 is provided with a similar wheel 62, these wheels turning in frictional contact respectively with .spring pressed friction blocks 64 and 66; and in order to prevent overthrow of the pawl carrying block 52, the circular bearing portion thereof is in frictional engagement with a spring pressed friction member 68.

The buttons are held in a receptacle or hopper 7 0,-the bottom of which is connected with an auxiliary receptacle 72 formed at one side with a circular opening in which is mounted the button conveyer wheel 46. The outer end face of this wheel is flat and provides a circular projecting flange 74 which serves to close substantially the opening in the receptacle, and the inner end portion is of reduced diameter and formed with a conical .peripheral surface converging toward the receptacle and providing seats for the lbutton heads, the wheel having slots 76 for the reception of the button eyes. The walls of the receptacle about the periphery of the button wheel present an inclosing surface inclined in substantially Aparallel relation to the conical surface of the wheel, and the bottom of the receptacle slopes toward the wheel so as to direct the buttons thereto. f In operation, the buttons will find their way into the space between the reduced portion of the wheel andthe surrounding wall with their eyes in the slots 76, the wall serving to conne the heads closely and thereby retain the buttons with their eyes in the slots. In order to prevent the buttons from slipping off the conveyer as they are advanced toward the upper portion of their path of movement, a guard 78 is located in position to serve as a retainer for the button heads.

From the above description it will be evident that if it is desired to use buttons provided With heads that are larger than usual, the conveyer 46 should be adjusted farther toward the left than shown in Fig. 3, so as to provide a larger space for the reception of the heads between the periphery of the wheel and the surrounding wall. Such adjustment is provided for through the mounting of the conveyer 46 for rotation upon a reduced portion of a spindle 8O which is supported for endwise adjustment in a bearing in the side of the receptacle 72 and has a head 82 by means of which such adjustment may be readily effected. A set screw 84 serves to retain the spindle in adjusted position. The shaft 44 is pressed endwise toward the wheel 46 by a spring 86, and has secured upon its other end a head 88 which serves to limit such endwise movement of the shaft and provides also means by which the shaft may be manipulated to adjust its squared end in proper relation to the recess in the wheel 46. 'When the set screw 84 is loosened the spring 86 will thus automatically adjust the parts in the positions represented in Fig. 3. VIf it is desired, however, to provide more clearance for the buttons about the carrier wheel, the spindle 80 and the shaft 44 should be pressed toward the left by means of the head 82, and

the set screw 84 then tightened. This arrangement provides also convenient means for releasing the buttons if they should become jammed between the carrier and the surrounding wall, as well as for emptying the receptacle 72, and to receive `the buttons thus released the machine is provided with a chute 90.

The staples, as will be clearly apparent from a consideration of Fig. 4, are picked up by the forwardly projecting pointed ends of the arms of the conveyer 38, and slide inwardly along the forward edge of each arm and then outwardly along the rear edge of the preceding arm from which they are delivered to the staple raceway. Although the ends ofthe arms move in close proximity to the walls of the receptacle 36 so as to prevent the staples from passing between the walls and the arm end, any tendency for displacement of the staples through frictional contact with the `walls is avoided by the provision of stationary plates 92 which assenza are separated only a sutlicient distance kto provide a passageway for the arms alone until they arrive substantially at delivering position opposite to the end of the staple racewvay 91, and are there cut back, as indicated at 06, to permit the staples to pass. rllhis arrangement serves not only to delay the passage or' the staples to the outer ends of the arms, but also to remove from the arms staples that are improperly positioned thereon, and permits the passage oi only such staples as are in proper position to enter the raceway.

Upon the same side of the conveyor 16 as the receptacle 72 is the receiving end of the button racevvay, this racevay comprising tivo opposite side portions 98 and 100 which are provided respectively with a slot 102 for the button eyes and a groove 104: for the heads. T he slot 102, as shown clearly in F ig. 5, is of suiiicient Width to permit buttons having heads of did'erent diameters to pass through the raceivay Without any tendency for the eyes to bind upon the sides ot the slot, although preventing the eyes from turning over in the raceivay. The raceivay is slotted, as indicated at 106, opposite to the delivery point of the oonveyer to receive the button eyes and it is suitably curved to deflect the button immediately, as it is delivered from the Wheel, into a horizontal position with its eye in the slot 102 and its head in thegroove 101. Above the slot 106 and the receiving end of the raceway is a guide 108 Which serves to direct the course or the button as it slides into the raceway and prevent it from falling over into the receptacle. rilhis guide is pivotally suspended, so that if a button should fail to enter the raceway properly or the racevvay should become filled with buttons, the guide may yield to permit the button to be pushed over the racevvay and into the receptacle by the following button. 1n order to dislodge from the Wheel any button that may be carried past the slot 106, the machine is provided with a bar 110 which extends obliquely over the sloping peripheral portion or the Wheel and acts as a deiiector to remove the button from the Wheel and return it to the receptacle 72; n

In order to insure the advance of the louttons along the raoeway and to remove from the ra-ceivay any foreign. matter that may become lodged therein, the machine is provided With means for directing blasts ot' air into the racevvay, comprisinga conduit 112 leading from an air pump 114e the piston of which is driven by a pitman 116 trom crank on the pulleyr20. rlhe air pump is operated in timed relation to the button conveyer Wheel and is arranged, as will be evident from an inspection of the drawings, to force a blast of air into the receiving end of the raceway immediately after the admission of a button thereto. The air blastvvill thus assist and hasten tie ymovement of the button along the raeeivay until it contacts with the end button of the series, and if there should be any tendency for any of the buttons of the series lo stiel; in the raceivay, the air blast will assist in closing the intervals between the buttons.

'llhe delivery end port-ion or' the button raceivay, as shown in detail in Figs. '7 to 10 inclusive, directs the buttons downwardly and rearwardly to a position-in Which the button eye is over the anvil member 118 and in line with one leg of a staple which is held at the end of the staple raceway in position to be advanced and driven by the staple driving member 120. The position of the end button is determined by a stop 122 Which is arranged to contact With the button eye and comprises a shouldered portion or" a plate 121 which is disposed at one side of the path of movement ot the driver 120 and assists in guiding the downward movement oi' the staples. The head vof the end button in the 1aceivay, as showninY Fig. 9, is positioned at the opposite side'of the plate 121 'l'roin the driving member, and its eye projects on the other side of the plate in staple receiving position. Y A f The fixed button supporting portions or' the button raceivay terminate at some distance from the end of the raceivay, and their places are supplied by springs 126 and 128 which are secured respectively to the side members 08 and 100 and are curved downivardly and rearwardly in position to support respectively the eyes and the heads of tivo or more of the end buttons. The end ot' the spring 126 rests normally in contact Twith the stop 122 so as to close the raceway, and the spring 128 is spaced a suilicient distance below the 'sprino 126 to provide for the reception of button heads of different diameters, and therefore may or may not contact with the heads When the buttons are rest at the end of the raceway. f Asthey button is engaged by the staple and depressed by the driving member for attachment to the Work, the spring 128 at the side of the anvil 118-and the spring 126 over the anvil are both depressed, and the latter spring is thereby separatedrom the stop 122 so to permit the button to leave the racen/'ay upon the subsequent feeding movement of the work. This depression Aof the springs has also the important function of displacing or agitating the button or buttons oirectly at therear of the end button, thereby obviating any tendency for the buttons to stick and fail to advance to the end of the raceway; and when Vthe end button is Withdrawn and the springs snap back into position, the buttons supported by the springs are similarly affected, but in amore positive manner. By reason, moreover, of the curved lform of the springs,their sudden return to position has the effect of throwing the buttons toward the end of the raceway and of bringing the end button positively into contact with the stop 122. v

The staplera'ceway 91as shown in Fig. S, is shaped to conform substantially to the contour of the illustrated novel staple hereinbefore referred to', which has upon' its head a substantially rectangular upstanding portion connected to the legs by portions of the head which are substantially straight and perpendicular to the legs and `which form stock engaging shoulders, this construction ofthe staple providing in the lower side of thchead. a substantially rectangular auxiliary recess which is elongated to permit a limited movement of adjustment of the button eye in the plane of the staple as shown in Fig. 10. yThe staple raceway is thus provided with an upstanding portion 95 substantially rectangular in cross section, and has at each side of the portion 9:3 a plane 4face 97 `to underlie and preferably be engaged by the shouldered portions of the staples. This racewayincludes also a cover or retainer'l() above the staples, and is curved to bring its end in close relation to the plate 121 so that the end sta-ple will contact with and be stopped by the plate without falling through the space between the plate and the end of the raceway. ln this position the staple is in the path of the driver 120 with one of its legs in line with the eye of the button which is in contact with the stop 122. In order to permitthe driver to pass' between the plate 124 and the end of the raceway. the end portion ofthe latter, including the cover 130, is pivotally connected with the main portion, as indicated at 132, and is held by a spring 13sL in its normal staple retaining position. fis the driver descende theend portion of the raceway therefore will yield to permit the advance of the staple and the driver as indicated in Fig. 9.

Below the end of the staple raceway is a guide member 136, the upper edge of which is curved or beveled at points below the legs of the staple, as indicated b v dotted lines in Fig. 9. This member serves, in cooperation with the plate 121, to guide the stapleas it. passes below the end of the raceway. and retain it' in position to enter the button eye and the work in proper relation to the clenching face ofthe anvil. One leg of the staple is further guided by means of a plate 13S which tits about the member 136 and projects at one side. substantially across the space between this member and the plate 124.. The plate 138is made of spring metal, and its edge adjacent to the plate 124 is suitably beveled or curved to permit the driving member 120, upon its lateral feeding movement which will be subsequently described, to move the plate in a direction away from the guide member 124 Vand pass out from betweenthis member and the guide plate 138.

It wil be noted, particularly by reference to Figs. 7 to 10 inclusive7 that the construction hereinbefore described comprises means for presenting a button with its eye substantially parallel to the work and means for positioning a staple with one of its legs in alinement with the opening of the button eye rela-tively close to that side of the eye which is outside of the staple, and that the driving member 120 is constructed and arranged to enter the button eye with its outer edge at one sid-e close to that portion of the eye which is outside of the staple. With this arrangement that portion of the button eye which is within the staple is opposite the central portion of the staple head and there is no danger that the buttonv eye may be interposed between the stock and that portion of the head of the staple which is adjacent to the leg so as to prevent the staple from being fully driven. In the novel staple shown that portion of the button eyev which is within the staple is received within the recess in the staple head and the shouldered portions of the staple which connect the recessed portion with the legs are of such length that one of them may pass with the adjacent leg through the button eye and both may be seated fiat upon the stock by the operation of the driving member. The end of this member, as clearly shown in Figs. 7 and 10, 100 is provided with a substantially rectangular recess complementary to the form of the upstanding portion of the staple head, with projections 121 at the sides of the recess, each of whichhas a substantially straight 105 end face'for engaging and pressing the respective shouldered portion of the staple flat upon the stock, and a substantially straight inner edge arranged to be located adjacent or contiguous to the respective side 110 face or edge of the upstanding portion of the staple head in the staple Vdriving and work feeding operations, Between the two projections 121 the driving member presents also a substantially straight face which is formed to stand in close relation to the horizontal bar across the upstanding portion of the staple head. The width of the forward projection 121. which is arranged to follow the shouldered portion of the staple through the button eye, is substantially equal to the distance between the upstanding portion of the head and the outer edge of the staple, as clearly shown in Fig. 10. The driving member as thus constructed 12 assists materially in keeping the staple straight as the latter is advanced and driven and in preventing distortion of the shape of the staple, particularly of the head portion of the staple, in the driving operation;

and by reason of the effective hold upon the staple which the driving `member thus secures, as vvell as the engagement of one of the projections 121 in the button eye, the driver is rendered particularly effective to feed the Work when feeding movement is imparted thereto in the manner to be subsequently described.

The staple driving member is carried by a lever which is pivoted at 142 upon a slide comprising two portions 1&1 and 146 rigidly connected and movable endyvise in a guidenf'ay in the base 6, and a bracket or frame 14.8 secured to trie member 146 and serving as a direct support for the lever 14:0. The forward portion 141% of the slide carries the anvil 118 which is thus positioned always in the proper coperative relation to the driving member 120. rlhe lever 140 is oscillated from the shaft el by a cam 150 Which is shaped for constant engagement With the opposite sides of a yoke shaped portion 152 at the rear end of the lever. The cam thus rest-rains the lever substantially from oscillatory movement independent of the movement of the cam, but permits the lever to move endvvise ivith the sides of the yoke 152 in sliding engagement With the cam. rThe slide member upon which the lever and the anvil are supported is reciprocated, so as to impart feeding and return movements to the driver and the anvil, from a cam 154F on the shaft d of substantially the same shape as the cam 150 and positioned diametrically opposite thereto. The cam 1511 serves primarily to oscillate a frame 156 ivhich isrpivoted to the machine frame at 158 and has an opening providing opposite and substantially vertical slidevvays which are engaged constantly by the cam 151 in the same relation as the cam 150 to the sides of the yoke 152. The frame 156 in its forwardly extending portion is provided with a substantially vertical slidevvay 159 in Which is mounted for sliding movement a block 160 having a bore in Which is pivotally mounted a stud 162 on a plate 164 forming a portion of a slide of Which the coperating member 166 is received in a vertical slot 168 formed in a rearwardly projecting portion of the member 1&8. lli? ith this arrangement, as ivill be evident, oscillatory movement of the frame 156. will impart reciprocatory movement to the slide vvhich carries the lever 140 and the anvil, so as to feed the ivork after a button has been attached and then return the members into position for another button setting operation.

Adjustment of the extent of the feed movement in order to space the lnittons as desired upon the ivork is effected through vertical adji ftment of the s e 186 and its attached plaie vvloi/rh to position the block in the slideivay 159 at differannessa ent distances from the pivotal point 158 of the frame 156. Convenient means for making this adjust-ment comprises a rack 170 secured to the bracket 1%8 adjacent to the slot 168, and a coperating pinion 17 2 mounted upon the end of a spindle 174e Which is journaled in a bushing 176 projecting from the slide member 166 through the plate 161. The outer surface of this bushing is screw threaded to receive a collar 178 which may be turned thereon to press the parts 16st and 166 into firm engagement With the sides yof the bracket 1L18and thus secure the block 160 in any position of adjustmen The spindle 174 may be turned by means of a hand Wheel 180 loosely mounted thereon and provided'with a pin 182 for engagement in recesses 184 in a head 186 secured upon the end of the spindle. A spring 188 between the end of the collar 178 and the hand Wheel tends to position the latter normally as shown in Fig. 6 vWith the pin 182 in one of the recesses 184. ln this position the Wheel may be turned to rotate the spindle and the pinion 172 and thereby change the length of the feed movements of the anvil and the staple driver. Previous to such adjustment, hovvever, it is necessary to loosen the collar 17 8, and this, as Well as the tightening of the collar, is effected by means of the hand Wheel through the engagement of a pin 190 on the Wheel in one of a series of recesses 192 in the end of the collar 178 when the v'heel. is pressed endvvise on the spindle in opposition to the force of the spring 188, i`

VEhe plate 164s, as shovvn in Figs. 2 and 6, carries a pointer which serves in coperation With a scale on the bracket member 148 to indicate the proper adjustment for securing the desired spacing between adjacent buttons or fasteners.

By reference to Fig. 2 it Will be seen that when the slide 148 is at its forward limit of movement, With the anvil and the staple driver in proper coperative relation to the racevvays for attaching a button to the Work, the slidevvay 159 is parallel to the slot 168, and that adjustment of the plate 164 and the block 160 to vary7 the extent of the feed movement vvill therefore have no effect upon the relation of the slide 148 and thevframe 156 when the parts are in this position. lllhatever may be the extent of the feed movement, therefore, the forward limit of movement of the slide 148 Will be the same, as is necessary for the proper coperative relation of the anvil and the driver With the raceways.

rThe feeding' movement of the anvil and the staple driver, as previously stated, takes place While the driver is at the end of its driving movement, the yoke shaped portion of the lever 140 at this time sliding rearwardly over the cam 150. ln order to prevent excessivev friction between the cam and the lever and facilitate the feed movement,

thev anvil .118. is mounted upon the slide member 1 44 `with yprovision for a slight downward or yielding movement away from thek driver 120 at the beginning of the rearward :movement of the slide. To this end the anvilhas a shank portion 104 extending through a bore in the slide in position to beracted upon by a cam 196 set in the bottom of the slideway. The anvil is prevented from turning bymeans of a pin 198 which engages in a slot in they shank portion 104, as well as by a pin 200 which engages in a recess in the member 144. The cam 196, as thus arranged, serves to upraise the anvil I when the slide is in its foremost position` i and when the slide is moved to the rear permits the anvil to yield sulticiently to relieve the driver carrying lever 140 from excessive pressure upon its operating cam.

Between Lthe feeding movements of the driver and the anvil and while these mem- Inl bers kare returning to their starting positions, the work must be heldeffectively in the position to which it has been advanced. For this purpose the machine is provided ,with cooperating clamp members 202 and 204 positioned respectively in front of the driving member and of the anvil. The upper rmen'iber 202 serves as a stationary .work abutment and is adjustable to determine the position of the plane in which the workis held, while the member 204 cai ried by a lever 206 pivoted to the base at 208 and held byfa spring 210 in position to press the work against the member 202, the extentof such movement ofthe lever beinglimited by an adjustable stop The lever is connected by a chain 214 to a foot treadle, not shown. whereby the presser 204 maybe swung downwardly away from the end of theanvil 118 to the extent permitted by a screw 216 engaging in a slot 218 in the lever. Such .movement of the presser member permits the work to be inserted in the machinev and adjusted upon the anvil .in position to receive the first fastener` and is of particular advantage in reA pair 4work ivliere, for example. it is necessary to a set a single fastener at the lower end of a button fly on a slice and it is difficult to adjust the material inthe required rposition upon the clem-hing face of the .wliereby'they are presented in they proper relative positions for attachment tojthe vwork through the movements of the driving meinber. If necessary, when` startingthe maoperated and the presser member 204 thereby depressed to permit the work to be properly positioned upon the anvil 118 for the attachment of the first button of the series. Such adjustment is-facilitated by reason of the -fact that the clutch is releasedto stop the machine automatically with the parts positioned as represented in Figs. 1 and 2 and the drivingfmember and the anvil in separated relation. When the work has been adjusted, the presser member is released and through the operation of the spring v210 presses the work constantlyV against the abutment 202 during subsequent operations.

The clutch actuating treadle is next depressed to connect the shaft 4 to the pulley 2. This results immediately in movement of the lever 140 through the operation ofthe cam 150 to advance the driving member 120 toward the anvil, the cam 154 in the meantime and during the entire downward -inovement of the driving member presenting its concentric-portions in engagement with the opposite vertical sides of the opening in the frame 156 so as to prevent anymovement of the anvil and lever supporting slide. The endl of the driving member 120 in its advance engages the top of the staple which isheld at the end of the raceway 94 in Contact with the guide plat-e 124, and pressing back the yielding end portion of the raceway, as shown in Fig. 9, advances the staple downwardly between lthe plate 124 and the guide members 136 and 138, passing one leg of the staple through the eye of the button atthe end of the button raceway,as shown in Fig. 8. and finally in cooperation with the anvil 118, sets the staple in thework i'n the manner shownin Fig. Vwith one ofthe forward projections 121 atthefend ofthe driving member engaged in the eye of-thefbut ton. During this movement of the driving member the spring 1,26 is depressed, as shown, to providean outlet for the button eye between the spring Vand the stop y122, and the spring 128 underthe head of the button is also depressed, the depressionof these springs, as previously explained, serving also toagitate other buttons at the rear of the end button so as to obviate any tendencv for the buttons to stick in the curved portion of the raceway.

rIhe driving member ha ving arrived at the end of its staple setting movement, they con- .centric portions of the cam 150-come into engagement withfthe opposite sides of; the

`yoke portion 152 of-thel'leverlfO soneto retain the driving member in the relation to the Work assumed at the end of the setting movement, and the cam 151iL simultaneously drawn from the raceivay and the springs 126 and 128 snap into position, thereby further agitating the buttons in the raceivay and imparting to them an impulse toward the end of the raceivay so as to insure that the eye of the end button shall be positioned in engagement with the stop 122. it the beginning of the feed movement also the shank portion 19a of the anvil slips ed of the cani 196 and thus permits the anvil to yield slightly and relieve somewhat the pressure of the lever 1d() upon the cam 150. @tiring Ythe entire feed movement the latter cam retains the lever in position to hold the driving member in eective feeding relation to the Work.

it the end ot the feed movement above described the cam 154: holds the slide in retracted position While the cam 150 swings the lever 1&0 in the opposite direction to separate the driving member from the ivorlr, after whichV the latter cani restrains the lever from swinging movement While the cam 15d returns the driving member and the anvil to starting position. During this move- -ment the anvil slips under the ivorlr Which is held by the clamp members in the position to Which it has been advanced, and at the end of the movement the anvil 118 isl projected upwardly by the cam 195.

1f the operator lreeps his foot upon the clutch actuating treadle, the above described operations will be repeated indefinitely, but if it is desired to attach only a single button the treadle will be released in time to disconnect the clutch When the parts arrive at the positions represented in Figs. 1 and 2. It Will be understood that the speed practicable for the operation of the machine permits the clutch treadle to be released in time to stop the button attaching operations at any point desired.
