LEATHER-WORKING MACHINE.

Speccaton of Letters Patent.

Patented J une 4:, 1918.,

To all whom t may concern: f

` Be it known that I, FRANK K. RUSSELL, a' citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Leather-Vorking Machines, of which the following is a specification.

This invention relates to leather-working machines and particularly to machines for finishing straps, traces and similar articles, and the object is to construct a machine which will, with one passage of thestrap through the machine, perform the various operations set forth. After a strap has been cutout of a side of leather, it is subjected to various treatments, and heretofore without my machine straps have been finished only after passing through a number of operations performed by hand by one or more persons who use one or more machines. The

edges of some kinds of straps must be trimmed and then blacked or stained. j The strap then goes through various smoothing processes and must usually be `properly creased by means of suitable rollers or'creasing devices. The edges of the strap must be still further rubbed so thatthe fiber will be made compact and smooth. The machine is further provided with rubbing devices which will approximate the act of rubbing a strap by hand. All of the above mentioned operations are provided for in a singlemachine and most of the devices for same are arranged in pairs and all of the devices are automatically adjustable vertically where necessary, and most of the devices may be laterally adjusted simultaneously. rFhe ma chine is further provided with feeding devices for starting straps in the machine and drawing the straps through or between the various treating devices. Other objects and advantages will be fully explained in the following description, and the" invention will be `more particularly pointed out in the claims.

Reference is had to the accompanying drawings, which form a part of this application and specification. Y

A

The mechanism for receiving and starting a strapinthe machine is shown in Figs. 11 and 12, which are detailed ,views on a largerscale thanlFigsjl and 2. The receivingand starting mechanism is4 mounted onbarsfl which are attached to the main frame "or stationary frame. A `"bracket A19 is; inouilsd on the Abars 18. Springs 20 and 21 `are @bolted to thev bracket f19 and curved under the racket, as" shown in Fig. 11. The spring 21 is extended forward of the bracket19,n Three springs 22,23, and ,24;u are Qattac'hedzto the springl21fand a rod 25 connects theuforward end of :the spring 21 wit-,hfthe ltwo springs 20 `and 21, as" shown iiillig.` 1l,` The "ends of these springs constitute bars for pressing thelstraps onjthe` feeders andy-are heldjustjabove theteeth of the feeders by` the y rod25 which is adjustable `by, the niit`26.

y 33 and34. ,indicate straps of ditierent thick nesses ywhichniay be treated bythe machine,

and the drawing shows the points at which the straps are tobe ,.fedto the machine. A

l movableclip orjlshield is 4mounted onthe guard 31 above 4thedoendin the guard and stands normally .in thelposition shown in Fig. .11 andis heldinthis position by spiral spring .36, `,which may be attached to the lower. part ofthe ,guardl and to the shield ,35.l A.`dog,;,37..is ,piioted to thesnield `55. y Thefeeder. 28 engages Vthe dog 37: byV meansl of, the shoulderfandthe dog 37. movesin a slot in guard 31 and carries the shield 35 therewith until the dog swings backen the left hand side of the guard 31 by'reason of the notch 40 in the side of the dog 37 and remains there until the feeder passes. When the dog 37 is released by the feeder 28 the spiral spring 36 drawsthe shield 35 back to its normal position.` The shield 35 goes through this operation as often as the feeder 28 passes through the shield. When the shield is carried to kthe strapwhich is ready for starting by the feeder the shield covers all the teeth of the feeder except the forward teeth. Consequently the extreme forward endof the strap must engage the forward teeth of the feeder and in this manner all the teeth of the feeder are made to engage the strap and it is impossible for the strap to be engaged by the rearward teeth only ofthe feeder for the reason that the rearward teeth are covered by the shield. lf the front teeth of the feeder engage the the strap then the springs 20 and 21 will press the strap on all the teeth of the feeder.

The guide arms 41, Fig. 3, are attached to f the adjustable frame of the machine and serve to center the strapon the feeder. By

. guides 42 means of these arms, Vtogether with the spring 27 the strap may be` properly started into the machine and the straps are afterward properly fixed on the feeder. The feeders 28 are `carried by two sprocket chains 42 and 43. Depressible guides 42 are provided for the chains 42 and 43. These are mounted by means of brackets 42 on the frame 1 by bolts `or rods 43 on which are mounted coil springs 43". Washers 44 form spring seats for springs 43". The guides 42 have a fixed upper limit in brackets 42, but are provided with yielding supports in springs 43 so that the guides'can be depressed automatically to allow a passing `strap to adjust itself in the finishing devices. These sprocket chains 42 and43 are endless and connected together at intervals and carry at intervals a plate 28 which constitutes a feeder The sprocket chains 42 and 43 are connected together by bars 44. The feeders or plates 28 are mounted on the bars 44 by the following devices: The bars 44 carry downwardly projecting lugs 45. Connections 45 and 45 areV pivotally attached to the lugs 45. A bar 46 is pivotally mounted in the connections 45 and 45. The bar 46 has cylindrical portions 47 and a coiled spring 48 is mounted on one end of the bar or holder 46 and presses aga-inst the connection 45 `and against a shoulde1246 on the bar 46. rlhe bar 46 is prevented from turning by lugs 47 whichproj'ect into a groove in the connection 45. The compression spring 48 holds lugs 47 normally in `the groove, but will yield sufficiently to permit the turning of the bar 46 so that the feeder l 28 can `he turned out of the path of the straps. The bar 46 has pintles or journals 47 which turn freely in the connections 45 and 45 and have free axial movement therethrough and also through the bars 44, The bar 46 carries tapering or conical pins or lugs 46 which together with a spring clamp 48 hold the feeder 28 normally in operative position, but by reason of the taper of the pins 46 and the spring 48 the feeder will slide ofi' the pins 46 if the feeder should come against some rigid object or be subject to abnormal strain against forward movement and thus not bebroken. rlhe feeder holder is rotatively and slidingly connected to the carrier chain. llhe lugs 47 serve to hold the feeder 28 in an upright position, but the spring 48 is lyielding so that the feeder 28 can be turned down laterally out of the `way of straps fwhich are being operated upon in case the strap is longer thanthe space between two feeders. The feeders 28 are supposed to be mounted on the double sprocket chain at suitable .distances so that a feeder will not interfere with thestrap which is being carried by the feeder `iu advance, but as above explained, in case of a very long strap some of the feeders can be turned down out of the pathof the straps. The feeder 28 is attachedto the bar 4.6 by lugs 46 and by the spring clamp 48. The sprocket chains are driven by the wheels 50, one being located at each end of the machine on shafts 51 which are provided with bearings 52. rl`he path of the feeder is so close to bar 20 that there is danger of the feeder teeth striking the bar 2O and mutilating the bar or injuring the teeth of the feeder. To prevent such `accident a hanger 52 is bolted to springs orbars 20 and 21. This hanger carries a roller 53. The bar 46 which earries the feeder will pass under the roller 53 and while the bar 46 is passing under the roller 53 the teeth of the feeder can not strike the spring 2O because the distance between the bottom of the spring 20 and the bottom ofthe roller 53 is permanently fixed and greater than the distance between the top of the bar and the top of the teeth.

The feeders consist of plates of metal. Each feeder is provided" with a plurality of teeth 54 and the forward edge of the feeder' is provided with a shoulder' to prevent the strap from being pressed. farther down on the front tooth than on the other teeth. Buit for the shoulder 55 the fixing spring would press the strap down too far on the front tooth because the spring strikes the front tooth with a more direct thrust than it strikes the other teeth. The teeth are more slanting at `the forward edge than in Fig. 7 so that cach tooth will stand 4at.

the proper angle to enter the strap approximately inline with the motion of the strap with reference to the tooth. at the time of:

the entering, 1t will beseenthat the strap will assume different angles from the time of the engagement of the'. front tooth and brushes 57 aremounted in troughs 58"and the troughs 58 are integral 'withframe pieces 59, which. are bolted to themovable frame pieces 3 and 11. The straps pass. over the inner edges of the troughs 58 and the edges of the troughs 'form seats for the straps. The rotary brushes are mounted on shafts 60. Each shaft 60 `is driven by'a pulley 61 and belt'62 and the belt isr driven by a pulley 63 which ismounted on the shaft 5l. Each shaft 60 is provided` with an adjustable collar 641. against which presses a spiral spring 65. These springs keep the brushes pressed toward the edgesof the strap. In this manner the wear of the brushes is taken up. The springs 466"and the beveled approach 79 to the troughs guide the straps to the brushes. The troughs 58 are supplied with bla'cking from cans 67. Each can 67 is provided with a mouth` or spout 68 `which is inverted with Athe spout68 in the trough. The blacking will-run out `untilsuflicient. blacking is in the trouglrto prevent the atmosphere from entering` the spout. As the blaoking is used up-.by vthe brush57 more blacking will'runout of the can, but the flow will stop as soon as the blacking closes the mouth of the spout 68.

After the edges of. the strapl have been blacked the lower or ieslrsideiof the strap is blacked For this purpose the troughsv 69 are attached tothe frame 1. The rotary brushes 7 0 are mounted in the troughs 69 lon shafts 71. The shaftsV 71 are drivenb-y pulleys 72 and belts` 7 3 and pulleys 74 which are mounted on shafts y60. The troughs 69 are supplied with blacking fronrA cans 475 which operate in the same manner as the cans 67 above described, cans 7 5' being-provided with spouts 76. The troughs 69have shallow portions 77 in which are-located up standing brushes 78 for brushing that part of the bottom of the straps which has not been blacked by brushes as the straps pass over the troughs. The bristles of brush-57 8 will'be forcedapart in the center byfthe feeder and the bristles arelso arranged that f they by their resiliency close ythe `opening made 5by the feeder after the passage of the feeder'. The shafts 71 are maintained inadjusted position by springs 70.` As, the straps are passing over theb'rushes 7 0' and`78they are held. down by Iweights 7 9; The weights 79 are lheldin place by upwardly proj eofting posts .80. The feeders 28 force the straps undertheweight. 79 :by reason of the shaped approach 7 9.

Afterthe straps have been Ablacked they pass through smoothing devices shown in detailin Figs. 26,"2'7 and 28. A bracket 81 is will cause the plate 86 to V'press"yieldingly on the straps as they are ypassing through thejsmoothing devices. Wipers`89 are at. tached to the plate 86,A and to ledges 83 by means `.of the 4brackets 90.` A hanger -91 :is attached to plate 86 for carrying a roller 92. The roller 92 rides on the nbars Z16 ofthe double' sprocket chain g and vcauses the plate 86 to risehighfenoughor causes the bar to sink low enoughto prevent the teeth of the feeder` from striking the plate 86. This will prevent thefeeder from inutilating the plate and `prevent the plate from injuringthe teethV of the feeder.

- After the strap -leaves-the smoothing devices'thel edges ofthe strap are `brushed by fast .rotating brushes 127l which are mounted oirshafts whichI are-journaled 1in vertical bearings-128 :and driven 'by pulleys 129 and belts 121. These brushesrun with sufiicient r speed-to remove thesurplus blackingwhich is thrown to the 4guards-127" by centrifugal force,from which itdrops-intoldrip 127 and drains linto a receptacle 128. `The creasing dev'icesare shown in Figs, 36' and `37. The creasing devices are arranged in pairs. Onlyl one of the pairs will be `describe`d.=' Aframe-piece 93 is attached to the laterally movable frame piece 4. This pen `frame piece193 carries a. ledge94-on which the straps are received and guidedto the creasing rollers 95 and 96.1l The creasing roller'95 is mountedon a shaft 97 "which is journaled in a bearing 9 8 carried by the'frame 93; The upper creasing-roller 96 Vis Vmounted on a shaft-99 whichisjofurnaled ina bearing l 100which=bearingl1simounted onstud 100 andisheld down by a yielding frame piece 101*'Whi`eh-is pivotal-ly mounted 'on a stud 102,'1Which Vstud" 102 isf rigid with the frame threaded and screws through a bearing 106 which is rigid with the frame 93. This screw 105 terminates with a crank by which` 1t may be screwed down more or less on the` bar 104 to increase or decrease the pressure of the creasing roll 96 on the strap which is passing between the rolls95 and 96.` The frame piece 101 carries a. guide plate rigid therewith. This guide plate 107 receives the straps and is set at an angle to receive a strap of any ordinary thickness. Means are provided for driving `the creasing `rollers 95 and 96. The sprocket chain 42 drives a sprocket wheel 108. This sprocket wheel drives a shaft 108. VShaft108 drives a cog wheel 109. Cog wheel 109 drives an idler cog wheely r110. Cog wheel 110 drives a cog wheel 111 which drives shaft 97 and cog wheel 112 and roll 95. Cog wheel 112 drives idler cog wheel 113 which drives an idler cog wheel 114. This cog wheel 114 drives a cogwheel 115 which .drives shaft 99 and y roll 96. A spring actuated catch 130 is provided for holding the wheel 96 in place and may be raised for removing and replacing said creasing roll. The roll 96 is vertically adjustable and may be driven in the different vertical adjustments by reason of the fact that the gearing 114 and115 is maintained at the same distance `apart by the bearing 100 and the arms 100 which are integral with bearing 100 and which are pivoted on stud 100. The bearing 100 thus has an upward swinging motion and cog wheel 115 will engage vcog'wheel 114 at ditferent vertical adjustments.

The @0g in is keyed'to shea 97 and is" movable axially on said shaft by reason of the key way 97 whereby the creasing rolls may be driven at any desired lateral adjust` ment, the creasing rolls being movedlaterally by the bracket 93 which is carried by the j frame piece 4. j

After the edges of the strap have been creased, the edges ofthe straps are burnished to make the same smooth and compact by the devices shown in Figs. 23` to 25 inclusive. An upright driven shaft 116 is mounted in a bearing 122 which is mounted on a pivot shaft 122 which is mounted in a bracket 117 which is attached to the movable frame piece 4. The bearing 122 is held normally against the wedge 131 by a spring 122. The shaft 116 is provided with a pulley 118 which is engaged by a belt 119. A pulley 120 which is integral with pulley 118 is engaged by a belt 121. A plurality of burnishing ringsl 123 are mounted on the shaft 116. These disks or rings have projections or teeth 124 which partly intermesh, that is, the teeth of strap. .The disks 123 are held yieldingly down by a spiral spring 125 which is held down by a pin 126. The teeth 124 are beveled from the inside and terminate with approXimately sharp edges, so that there will be a minimum amount of surface between the edges of the teeth and the adjacent disk.

The object of this construction is to prevent particles of leather or ink from`accu1nulating in a position to hold the disks 123 apart. The disks 123 have upwardly extending hubs which perform two functions. The hub will form a bearing to hold the disks in a` proper horizontal plane and prevents dirt from accumulating on shaft 116.

Provision is made for holding the burnishers 123 at different vertical adjustments. The pulleys 118 and 120 may be formed integral. The pulley 120 rests against the top of bearing 122. The hub of pulley 118 has a notch therein and a plurality of holes are made inthe shaft 116. A pin 118 is to be inserted in the holes to hold the shaft at different heights. The pin rests in the notch j in the hub. The distances between the holes in shaft 116 correspond to the difference between the groovesformed by the disks 123. A strap may be made to enter any one of the grooves by setting the pin in the hole in shaft 116 which will raise the groove to the desired height.

The bracket 117 and bearing 100 carry devices for regulating the pressure of burnishers 123 on the straps. An arm 131 is attached to bearing 100 and projects between bearing 122 and cam 132. The object of this l .arm 131 is to regulate thepressure on the burnishers 123, in proportion to the thickness of the straps. As the roll 96 is raised upward by a passing strap, the arm 131 tween the bearing 122 and the cam 132, thereby forcing the teeth 124 of `the disk 123 against the straps. A lever 133 is rigid with the pivot shaft 135 of the cam 132; A rack forces the wedge shaped member 131 bemay be formed integral with the bracket 117 end of the shaft 135 and thus holds the lever 133 on rack 134. A bolt 136 presses against the cam 132 to hold the sam in position against the wedge 131.

leave a vertical slot .for the: passage of the feeder. fjApairof right and left brushes 153 are journaled fin the two casings 151 and set atyanangle. The bristles which forni the brushes are'farranged in cone shapes, the

l, `large ends projecting in close proximity to 'thepath of thehfeeder and the two rotary brushes are set at .an-angle so that the two brushes will present a contlnuous surface on the `top side thereof. Thus "the strap is i brushed .entirely across the top and entirely across the bottom. AThe obj-ect of having two shafts; orftyvo brushes is to permit the passage of the'feeders andthe object of the cone-shapedbrushes set at an angle is that .the bristles may closethepassage of the `1feeders and brush all partsof the lower side of the strap. "The shaftsile` arep'driven by pulleys 155 and belts 156t`helatter being driven by pulleys 157 which are mounted'on shaft lil-8. A' brush 158` is mounted inthe upper casing 161 and is'driven' from the same shaft 148. Thecasing 161 `isprovided with a dirt boX159 for. gatheringltheidirt or other matter thrown from `the straps the brushes. The upper part 161 is yielding and is held in` operati-ve position by `the spiral spring 162 lwhich attached to the outside ofthe casing and to bra`cketi1'63 whichis rigid `witlifthe frame 1. The spring 162 partly supports the c asing161 vand prevents the leasing from resting too heavily on passing straps. The greater part of the-dirt 4will pass between. guai-ds: 1.60 and lfand fall out, andA practically all the dirt which remains momentarily in thelbristleswill` be thrown througlr slotl 161 .fintobox' 159.
