ZMACHINE FOR SETTING FASTENERS IN SHEET MATERIAL.

Application filed October 31, 1917. Serial No. 199,498.

To all whom it may concern:

Be it known that we, GEORGE M. EAMES, and Gnonen W. Jaoonns, citizens of the United States, residing at Bridgeport and Stratford, respectively, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Setting Fasteners in Sheet Material, of which the followingis a specification, reference being had. therein to the accom iianying drawings.

This invention relates to machines for setting fasteners in sheet material such for example as the uppers of boots and shoes, and is herein shown as embodied in a machine of the duplex type for setting eyelets in each of two superposed pieces of such material, but itis to be understood that many of its features may be advantageously employed in eyeleting machines of other types as well as in machines designed to set fasteners of other kinds such as lacing hooks, or studs.

hiachines of this type as known commercially at the present time are subject to many defects in operation among which may be mentioned great complexity of parts resulting in high cost of manufacture and upkeep, uncertainty in action especially when attempts are made to run them at high speed, due to the use of spring'control of many of the essential operating parts, as wellas failure to supply proper means for supporting, holding and guiding the work while being operated upon.

It is the object of this invention to overcome the above defects and difficulties as well as other and minor disadvantages inherent in the old types of machine but not pointed out in detail above.

More specifically, it is an obiect of this invention to so construct a machine of this character as to avoid undue complication of parts while at the same time retaining all the advantages of adjustment and adapta hility to various types of work possessed by the old machines.

It is a further object of the invention to obtain the feeding action or the punching and setting operation or both by mechanism which gives a positive control of such operations'at all timesboth on the active and return strokes of the parts, thereby 21V01Cllngthe use of springs and permitting of driving the machine at all speeds with equal certainty of operation.

It is another object of the invention to provide an improved form of hammer, or punch and set operating device, providing for ample relative adjustment of the stroke of the punch and set in operating upon the work.

Another object of the invention is to pro vide improved means for supporting and guiding the work while being operated upon, said guiding means being adapted for ready adjustment and also serving as a holddown for the work during withdrawal of the set from the clinched eyelet.

An important feature of the invention and one which is believed to be broadly new in this class of machines comprises a work hold-down or presser-foot device for holding the work in position upon the work support, this device being always under tension of a light spring to hold the same against the work support, but being automatically subjected to heavy tension at the moment of operating upon the work. Means, herein disclosed as embodied in the presser-foot, but which might be incorporated in a separate element, if desired, is also provided for constantly feeding the work toward the edge-gage to insure proper alignment of the fasteners. v

Other features of the invention, in addition to those above referred to and including important details of construction and improved combinations of parts, the advantages of which will be clear to those skilled in. the art will be hereinafter more particularly described and claimed.

These and other features of the invention will be best understood and appreciated from the following description of a pre ferred embodimentthereof selected for purposes of illustration and shown in the accompanying drawings in which,

Fig. l is a front elevation of the machine, tipped backward to more clearly show the construction. Fig. 2 is an elevation of the left hand side of the machine of Fig. 1.

Fig. 15 is a sectional 'detail of the locking device for the clutch elements. Fig. 1.6 is a front elevation showing the fastener feed mechanism of the machine. Fig. 1'? is a plan view of the structure shown in Fig. 16. Fig. 18 is a sectional view through the hopper device of the feed-mechanism and Fig. 19 is a detail view of the gatemember and its supporting parts, removed from the hopper.

Frame and dm'ce mechanism.

The base of the machine is indicated at 1 this base being of any suitable form adapted to be mounted upon a bench or other support. Extendingupwardly from the base member are a series of supporting arms on brackets 2, 3, and 4 which brackets may be integral with the base member as herein shown or may, if desired, be formed as separate members. Of these brackets two adjacent brackets 3 and 4 are extended upwardly-and forwardly as clearly indicated in Fig. 2 and provide at their upper ends aligned bearings 5 and 6. At a point near the lower ends of the supporting brackets 3 and 4 a second pair of aligned bearings 7 and 8 is provided. The purpose of the above set of bearings will be hereinafter described.

At the upper end of bracket 2 is provided a bearing 9 and in alignment therewith in bracket 3 is provided a second bearing 10, these bearings forming a support for the main drive shaft to be hereinafter described. Formed upon the upper part preferably of the central bracket 3 is an inclined supporting surface 11 and projecting outwardly from the rearward part of the same bracket 3 is a secondary bracket 12 also provided at its upper portion with an inclined supporting surface 13. The base member with the brackets projecting upwardly therefrom having the bearings and supporting surfaces described constitutes the frame of the ma chine and it will be noted that this frame as disclosed is formed as a single integral casting, thus producing an extremely simple and cheap construction requiring very little machine work to adapt it for supporting the various parts of the machine. \Vhile as stated this structure is shown as an integral castingit is to be understood that it is fully within the scope of this invention to form the frame of several independent elements suitably connected together. The main purpose of this feature of the invention, however, is to provide a simple and strong supporting. structure for the operative parts. I

In-machines of the present type as heretofore constructed it has been found desirable to mount the work-rest and the operating tools in an inclined position with respect to the horizontal plane in order to present the surfaces of thework in a plane normal to the line of vision of the operator. In previous machines it has usually been found necessary to employ specially formed interpositioned supporting devices between the frame and the various operating parts in order to properly position the latter in an inclined position as above described, but by reason of the arrangement in this machine of the supporting brackets having their upper ends forwardly inclined as above described and the provision of forwardly inclined supporting surfaces such as 11 and 13 it is possible to directly support all of the operative parts of this machine in the desired inclined position upon the frame structure thus again tending to simplify the machine and to decrease the cost of production of. thesame. This is believed to be a valuable feature of the invention and has been broadly claimed herein.

The main .drive shaft is indicated at 14 and is shown as provided upon its right hand end with the usual hand-wheel 15 fixed thereto. Located upon the drive shaft between the hand-wheel and the bearing 9 is a drive mechanism including a clutch indicated generally by reference letter a. Mounted between bearing 9 and bearing 10 is a feed-cam 16, a tool operating cam 17, and a pulley 18. Fixed upon the left hand end of said drive shaft and extending beyond the bearing 10 is an eccentric pin 19 (see Fig. 9) the purpose of which will be later described.

The clutch mechanism above noted may be of any suitable type but is here shown as of the form known as the Horton clutclnan example of which may be seen in patent to Horton, 260,394, July 4, 1882. to which ref erence may be had for a disclosure of this general type of mechanism. It is believed sul'ficient herein to describe this clutch gen shown 1 at roterv movement of the hen erally as coniprising u collar 20 fixed upon member ll. about the axis the bin the shaft said coller being pro ided With e ci-iuse outward movement of the in stop-lug or shoulder 2. u bearing boss 21,' .7 oi the shrine;

in the drawings i 1.2 and 13) the machine is shown as at t, the stop arms bethe stop lugs of the clutc clutch-blocks 29 being shown. in neutral position. At this time the spring 27 is under compression tending to turn the c ch member 24- with respect to the collar 20 but is riined from such movement by the on devices. Upon move the arms and I cam surfaces 60 and 61 of the stop arms hereby separating the free extremities of the stop arms and thus disengaging them. from the stop lugs. At the instant of release of the lug a l from its stop arm the spring 27 expands thereby causing a partial rotation of the clutch-ring 2-1. his movement causes the clutch blocks 29 to ride up upon the cam surfaces of the cam 22 and thereby clutches the continuously rotating pulley 30 to the drive-shaft permitting a positive drive of the same. Upon release of the treadle or other means for controlling the arm Get the spring which is under tension draws the free ends of the stop arms 57 and 58 toward one another and into the path of the stop lugs 21 and e14. l pon engagement 5 the lug 4 with its stop arm the ring is stopped and the cam 22 rides out from ben th the clutch blocks thereby releas' the driving shaft so that the in oinenti n of the machine puts the spring 27 under tension. i it the instant of release of the drive shaft the re the respective stop-arm goes beneath the lug 21 and thereby prevents reverse rotation of the shaft. it will be noted that by reason of the interposition of the buffer member 48 between the stop-arms and the frame of the machine the shoclr due to sudden stoppage of the parts is to a large extent absorbed, thereby avoiding undesirable strain in the machine parts.

During the normal 0 eration. of the machine the pin 36 is in retracted position the handle 41 being located in the enlargement .2 of the slot l-O thus providing for independent movement of the collar 20 and the clutchu'ing 24. it at times desirable to turn the drive shaft by hand while the driving pulley is still running, but it is vident that in the series of operations above described this is impossible for as soon as the stopping devices are thrown out of action Q's-pulley is clutched to the f for ving the same and upon stopping the machine the drive-shaft is pos ivel l clred 11st manual operation. 7 The pof the pin 36 is to permit of such manual con- 1 eaees trol' of the drive-shaft with the machine stopped.

Upon release of the pin 36 by manipulation of the handle ll the spring 38 projects said pin to such a position as to cause its end to engage the opening 4L3 in the clutch-ring thus positively locking the and collar together. It will now be evident that ifthe machine be stopped and the pin 86 thus released to couple the parts together, the stop arms may be retracted from the stop lugs withoutany operation of the clutch elements, theclutclrring 24- being restrained from turning movement under action of the spring 27 by reason of the lock. engagement of the pin 36. The drive shaft is now free from the stopping devices and also free from the drive pulley and may thus be turned freely by hand for adjusting the various mechanical parts or for any other desired purpose, it being evident that by this operation the drive shaft may be turned by hand without the necessity of turning the countershaft and inter mediate driving connections. Whereas in clutches of this type asheretofore known erein stop-arm is employed, a large un anced force has been developed which must all be absorbed by the machine frame, in this device the arrangement of the stop a? l 'everse arm upon the same support and upon opposite sides of the shaft, together with the manner of mounting the support serves to balance the thrust developed in stopping, thus relieving the adjacent frame p rts of undesirable strain to a very large No claim are made herein to the p 1c clutch mechanism above described, which mechanism forms the subject matter of copending application Serial. #199,486. tiled lcto er 31,1917,by George M.

Tool operating mechanism.

Located in the aligned bearings 5, 6 and 7, 8 are pair of shafts 70 and 71 having fined thereto between said bearings the respective arms 72 and 78, said arms being provided near their outer extremities with suitable hammer devices for operating the fastener setting tools. idigidly attached to the shaft 70 is a crank-arm 741- and attached to the adjacent end of the shaft 71 is a similar crank-arm 74;. Carried upon the outer extremity of the respective crank-arms are cam engaging rolls 75 and 76, (see Fig. 11) said rolls being adapted to engage camrooves 7'? and 78 formed upon the opposite ateral faces of the tool operating cam memer 1?, the latter being fixed to the drive shaft. The cam- grooves 77 and 78 are adapted to swing the crank-arms l and 74 and thereby the hammer carrying arms 72 and 73 positively in both directions of move ment thereby avoiding the necessity for the use of resilient retracting means for said parts as is common in the prior art construction.

Reference may be had to Figs. 6, 6", 7 and 8 of the drawings for the detailed construction of the hammer device. As the hammer members for both the upper and lower fastener setting devices are of similar construction it will be suflicient to refer to the construction of the upper of these devices. The hammer arm 72 is bifurcated at its outer extremity to form two opposing arms and 81. Fixed upon the upper surfaces of these arms by suitable fastening means as screw 82, see Fig. 3, is an angular plate 841 said plate forming a cover for the space between said arms and also serving as a closure for the space between the extremities of said arms.

Located within the chamber thus formed between the arms 80 and 81 and the plate 84 is a vertically slid-able plate 85 said plate being vertically adjustable by means of a screw 86, said screw being provided with a suitable locking means 87 for holding the same in said position. Also located within said space and vertically adjustable is a U- shaped frame 88 having the closed side 89 thereof in engagement with the plate 85, said frame 88 being suitably frictioned against the walls of said space by set- screws 90 and 91, and a plate 91 is interposed between screw 91 and the ends of frame 88. The arms of said U-shaped frame are provided with inclined grooves 92. Slidable within a suitable slot 93 in the cover-plate 841 is a block 94 said block being supported in said slot by a plate 95 overlapping the edges of said slot and secured to said block by a screw 96. The block 941- is provided with oppositely projecting tongues 97 adapted to take into the inclined grooves 92 of the U- shaped frame. An adjusting screw 98 is threaded through one arm 81 of the hammerlever and has a positive connection of any suitable character, permitting relative vertical movement between said parts, with the slide-block 94 whereby movement of the screw in or out produces sliding movement of similar character in the block 9 1. Suitable locking means 99 may be provided for the screw From the above construction it will be clearly evident that the plate 85 may be vertically positioned by the adjusting screw 86 and that the vertical position of the ll-shaped frame 88 may also be adjusted by turning the screw 98 thereby causing a sliding of the block 941 which through the tongues 97 acting in the inclined groove of said frame produces a vertical adjustment of the latter. I 1

Punch and set mechanism.

punch. being located within the tubular set,

the punch and set being laterally movable for setting the work and beingrespec-tively operated at different times during such movement. This machine is of the duplex character employing oppositely disposed punch and set devices. As the two punch and set mechanisms are substantially identical it is believed to be suflicient if one of these is described, and reference may be had to Figs. 2, 3, 4L, 6, 7 and-8 for a'full disclosure of these parts. As previously stated the central bracket of the frame is provided with an inchned supporting surface 13.

Fixedly mounted upon this supporting surface is a bracket 100 said bracket being provided with a vertically extending portion 101 having at its upper and lower extremities suitable bearings 102, 103. Mounted within these bearings are adjustable pintle pins 104, said pins being adapted to be fixed in adjusted position by means of setscrews 105. Supported between said pintle pins and for pivotal movement therein is a lever member 106 said member being provided with suitable bearings 107; The lever member 106 is herein shown as of substantial vertical depth and as being bifurcated at its free end to provide two opposed arms 108, 109 provided with bearings 110, 111 at their respective outer ends. Mounted to slide vertically within said bearings are the fastener inserting tools and as this machine is of duplea form and the opposedv sets of tools identical it is believed sufiicient if one of these sets of tools is herein described.

Referring now particularly to Figs. 6, '7 and 8 it will be noted that within the bear ing 110 is slidably mounted a sleeve 112 said sleeve having formed at one extremity an enlargement or head 118, this head serving to receivethe blow of the operating hammer. The opposite extremity of said sleeve 112 is counterbored to provide an enlarged cham her 114 thus forming at the inner extremity of said chamber a shoulder 115. The outer extremity of said sleeve is screw-threaded internally at 116 and is adapted for screwengagement with the fastener setting tool 117 the latter being shown as provided with an integral sleeve 118 projecting within the chamber 114: and providing by its upper extremity a second shoulder 119 opposed tosaid first named shoulder. Mounted to'slide within the sleeve 112 is ahollow punch supporting shank 120 said shank being provided at its lower end with an outwardly projecting flange 121'. In the chamber 111 and between said 'shoulde 115 and the flange 121 is located a coil spring122 said spring having its bearings upon the shoulder 115 and the. collar 121 thereby tending constantly to project the shank 120 in a direction toward the setting tool. Located within the hollow setting tool is a hollow punch 123 said punch being provided at its rearward extremity with a flange 124 and with a central teat 125 said teat being located within the lower extremity of the. shank 120' and serving to center the punch within the same. The shoulder formed by the extremity 119 of the set 117 serves as a stop against which the flange 124 bears to limit the movement of the punch in an outward direction, the spring 122 tending always to keep the collar 121 upon the shank 120 in contact with the flange 124.

Any suitable meansmay be'provided for I normally moving the'punchand set devices to inoperative position such 'means being herein shown as a lever 126 p'ivotally mounted upon a lug 127 extending from the arm 108, said lever being bifurcated at its free end to provide arms 128 adapted toiengage beneath the enlarged head 113 ofv the hollow sleeve 112, said 161 615126 being. normally tensioned bya spring 129 bearingv against the same in a direction tending to move the punch and set to retracted-position.

A modified type of mechanism for retracting the punch and set devices is illustrated in Fig. 6 of the drawings,- this being a very simple and satisfactory arrangement and the preferred form, and that which is claimed herein. Upon the hammer-lever 72 is a boss 72 having a machined surface 72 forming a. bearing for. a forked arm 72 ,.the latter being pivotally mountedto swing upon said bearing surface byapin 172. At its forked extremity the. arm 7 2 isadapted to. take under the enlarged head 1130f .thehollow sleeve 1.12. .The arms'of lever 7 2 are shown at'72 as humped up: slightly near their outer ends. to provide a better'bearing for engagement with the head of sleeve 112. It will. readily be seen that with the above construction upward .movement of lever 72 .in retracting the hammer, serves by reason of the engagement of lever 7 2 with head 113, to positively lift'the sleeve 112 and that the pivotal mounting of lever 7 2 permits the same to follow sleeve 112' in its lateral feed movement, thereby maintaining a constant engagement between the parts. It will. be obvious that lever 72l'ma'y' be of some resilient material as for example spring steel to avoid unnecessary shocks ,in' operation: or if desired to retain the head 113 alwaysin contact with the hammer member.

Fixedly" mounted upon the 'lever'farm 106 near its'forward end is an anvil supporting member' 130' said anvil member being provided with a combined punch-anviland; set ting tool 131, such tool being removab'ly secured in said sup'portby means of a pin 132 the punch-anvil and setting tool being of old and well-known character such as is com.- monly employed in machines of this type. In the present mach-inehowever, the pin 132 engagesrthe member 131 loosely, thereby profor: a slight freedbnrof smuvementvof the latter with respect to the support 130, a feature which is desirable in a machine of this type, enablin the part 131 to automatically center itself with respect to the oppositely acting punches and sets.

Feeding 'mec/lmrism.

In this machine the material operated upon is fed by a lateral movement of the and 3, provided with a suitable cam groove Projecting rearwardly from the upper portion of the bearing bracket 2 is an arm 136 provided at its extremity with a bearing 137 for a vertical shaft 138, (see Fig. 1) said shaft being mounted at its lower end in a suitable bearing 139 carried by the base of thelmachine and in alignment with said first mentioned bearing. Fixed to the upper end of the shaft is a lever-arm 140 and mounted loosely upon the shaft 138 by means of a pair of spaced bearlng lugs 139, .].S a bell crank lever 141 shown in Fig. 1 as just above 1 of the treadle serves to turn Said lever, it being obvious, however, that other and equivalent means may be substituted for the above controlling devices.

Surrounding the shaft 138 is a coiled spring 145 (see'F 1) having one end thereof secured to the bell crank lever 141 andhaving its'other-end'bearing upon the frame of the machine, said spring being so .tensioned as .to normally tend to move the bell crank-lever in clockwise" direction as seen in Fig. 3 of thedrawings. The lever 140 is provided with. a T-shaped slot 146 saidslot as seen. in plan being-of arcuate form, the curvature of said slot being. concentric withthe pivotal connection or link 134 to lug 132 when the parts are in initial position with the punch located for the punching operation. Slidable in said T- shaped slot is a bolt-head, the bolt projecting upwardly therefrom as seen at 147 said bolt extending freely through an opening formed in the end of link 134 and being with. a. nut..148 whereby the. link 1 ,asaeee may be properly secured in position upon said bolt. Also secured within said slot and upon opposite sides of the link ronnectingr bolt 147 are stop bolts 149 and 150 said bolts beingprovided with suitable nuts for locking the same within the slot. It is evident that by loosening the nuts said bolts 14-9 and 150 may be adjusted. to ditlerent positions in the slot and may thereby serve to limit the movement of? the link CODTLQCtlIlg bolt 1. 17 in said slot and to different pa hs of movement therein. By reason of the spring-tension of the bell crank-lever 141 and the connection thereto of the link 13 i by the link 143, the link 134; tends to move in a counter-clockwise direction as seen in Fig. 8 or toward the fulcrum of the lever 1 10 and it will be noted that upon movement of the lever 1 11 by the operator the position of the bolt 1 17 and the link 13-1- may be varied within the limitation imposed by the positions of the stops 14:9 and 150, Fixed to the lever 1410 is a lug said lug being provided as shown in Fig. 1 with a cam engaging roll or stud 15? said. stud being located within and adapted to be actu ated by the cam groove 135.

Upon operation of the drive shaft the cam 16 through the lever 1&0 and the link 134 will cause a rocking movement of the lever 106 and thereby will cause a lateral swinging movement of the punch and tastener setting device. As the cam actuates the roll 153 positively in both directions it will be seen that the arc of travel oi the lever 140 is constant but by reason of the adjustable connection of the link to said lever whereby the effective length of the lever as a means for moving: the link u'iay be varied, the arc of travel of the lever E06 and therewith the punch device may be varied. By reason of the fact that the slot in lever 140 is formed as a circular are about the pivotal connection of link 134i to lug 132, when the parts are in normal position adjustment of the link 134 will not vary the initial position of the lever 106 or of the punch carried thereby but will merely adjust the length of travel of these parts.

The operation of the punching and setting devices may now be briefly described. l Vith the parts shown as in Figs. 1 3 and 6 the lever 106 is in initial feed position, the punch and set being fully retracted. Upon operation of the drive shaft the cam groove 185 being provided with dwell at this point retains the said. lever 106 in initial position. The hammer operating cams 77 and. 78, however, are provided with active ele ments at this point and produce a striking movement of the hammer. This mo ment is only suilicient to partially project the set ting device by contact of the ll-shaped frame 88 with the head 113 but at the same time causes contact of the plate 85 with the upper extremity of the shank 120 of the punch the movement of. the he 'mier being sufl icient to cause the punch to c1 rage the work and form an opening there he set. however, not bei v projected enough to come into contact "1 Th, it being understood that in its outward movement the punch has been supplied by suitable means with a fasten six tor example as an eyelet.

Upon a further turning movement of the drive shaft the teed-cam 16 which is provided with an advanci portion cause; a lateral swinging moveme t oil. the lever 106 and therewith of the punch and set devices this lateral swinging movement serv ing to move the hammer portion of. the shank of the punch out "from unnerthe plate 85, the punch at this time rest ing upon the anvil 131 wh ch it will be un derstood par-takes of the lateral movement oi the punch and set so as always to be in registering relation thereto. The cams 7? and 78 now present a further operative portion which causes increased movement of the hammer members and as at this time as before stated the punch shankhas been it oved from below the slide 85, no further action of the punch will take place, the up per portion of the shank thereof illtllti? ed 95 in F 8 being free to extend between the arms oi the iii-shaped frame b8. under iii-- creased pressure of the punch upon the anvil, The arms 0' said frame l owe e". in the further downware movement i, the; hammer bear heavily upon the enlarged upper extremity 118 of th 1123 and thereby de n'ess the set int relation with the fastener to cli same in the opening in the m ri l cams 77 and 78 now present a portion which upon further rotation or the shaft causes the hammer devices to be turned to inoperative position while at substantially the same time the teed can thereby of the punch to initial feed postion. erations is repeated to the drive shaft thus punching and settii ments of the mat. actions it being); cle son of the e the material dui puncln the material. mus! with.

Jportnig surface 11 of the central bracket is an arm 154C said arm being provided with a foot 360 pivotally mounted at its rear end by means of the bolt 351 and be' provided its forward end with a slot e50. D

l. assing through said slot into the supporting surface is a bolt 352 by means of which the arm 154 may be adjustably fixed in position laterally of the supporting surface. Such adjustment is desirable at times for adjusting the delivery ends of the raceways which are supported at their upper enc s by devices carried by said arm 15%, the purpose of such adjustment being hereinafter described. The arm 154i is 3r vided its outer extremity with an inclined bearing boss 155. Loosely supported within said bearing is a sleeve 156, said sleeve having integral therewith or fixed thereto a plate 157 resting upon the upper extremity of said bearing 155. The plate 157 forms the base of the receptacle for fasteners, said base being provided with a series of brackets 158 adapted to removably support a drum or hopper 160, suitable means such as bolts and wing nuts 159 bei. provided for holding the parts in fixed relation.

The hopper 160 may be provided in its upper wall with a suite is opening for filling the receptacle with fasteners. s illus trated herein automatic means may be provided. for feeding fasteners to said hopper through the opening formed therein and such means may consist of a suitable reservoir 161 supported upon a braclr 162 from the frame of the machine and haiing feedspout 163 extending downwardly through the opening into said hopper, said reservoir being adjustably supported. upon its bracket whereby to vary the distance of the extremity of the feed-spout from the bottom of the hopper thereby serving to provide m .ns for adjusting the feed of fasteners to me hopper. Such hopper supplying means is well known and no claims are made herein to this structure.

Mounted for rotation within the sleeve is a shaft 1 4;, saidshaft havin fixed at its lower end a gear 165 and having mounted upon its upper end a dishedplate 166, said plate being attached to the shaft by any suitable means such as a screw the convex portion of said plate being uppermost. \Vithin the rim of said plate are a series of radial openings 168 adapted for the reception of individual brush-tufts 169, the arrangement being such that the tufts extend outward in a direction substantially parallel to radial elements of said convex surface of the plate. that is to say, in a direction some what inclined to the shaft Such tufts may be provided with ferrules 170 of any suitable material adapted to hold the bristles of said brush in proper relation, said forrules fitting within the openings formed in iae neee sail plate and being independently secured therein by set-screws 141 or by any other suitable means.

machines of this type as heretofore known. no means has been provided for the L M. of 'ne oi. more i tie rus 1 enew o o l b h tufts f, as frequently happens, such tufts become loose or worn before the remainder of the brush, thus necessltatlng removal of the en- .tire agitating device and substitution of a new one, whereas by applicants construction one or more individual brush tufts may be renewed at slight cost and small expenditure of time and labor, the desirability of which will be understood by those skilled in the art. l-Vhile the above method of securing the brush to the plate is a preferred form it is not to be understood that this invention is limited to the specific means shown as it is clearly evident that any other suitable equivalent means may be substituted therefor within the scope of the claims herein presented.

Mounted upon the upper end of shaft 164 and above plate 166 is a convex supporting or baffle plate 400. This plate may be secured to the shaft in any suitable manner as by means of the same screw 167 as is employed for holding plate 166 thereto. This supporting plate is of a diameter slightly less than that of the agitator extending herein shown to cover all but substantially the outer half of the brush tufts, thus leaving only narrow circumferential channel between its edge and the wall of the hopper for the passage of fasteners downward into the path of the brush.

The purpose or function of this plate is to supgort the mass of fasteners in the hopper. thus relieving the brush tufts of this duty to a large extent and resulting in only a comparatively small number of fasteners being swept around by the brush and presented to the discharge opening. In many machines of the prior art difiiculty has been experienced, especially when the hopper was well filled or when attempts were made at automatically replenishing the hopper from a supply reservoir in securing a uniform and steady flow of fasteners from the discharge opening, but by provision of the baffle plate herein disclosed, the above difficulty has been overcome. Projecting from the supporting arm 154- are a pair of lugs 172, said lugs being provided with aligned bearings within which issupported a shaft 173 said. shaft being provided at its outer extremity with a gear 174 meshing with the gear 165 and being provided at its opposite extremity with a pulley 17 6, (see Fig. 1). Pivoted upon a convenient portion of the frame is a lever 177, (see Fig. 2) said lever being provided at its free extremity with a stub-shaft 178 having freely mounted upon the same a pair of guideepulleys .179, (Fig.

usually Ti 3). The lever iii also provided near its center portion with an adjustable set-screw 178 adapted contact with the frame of the machine and'thereby form an adjustable stop for said lever. Passing about the pulley 176 and the pulley 18 upon the driveshairt is a belt 180, saidbelt passing at its intermediate portions about the guidepullevs 1.79, adjustment of said latter pulleys :ltor tensiening the belt being provided by the set-screw 1.78. i

The base-plate 157 is provided at one side with a downwardly depressed area indicated in l 18 atfllfi'z", said area merging into the elines 157 at its ends. The drum. 160 is provided with a slot 181 located at its edge and adjacent the depressed portion of the base-plate 1537, thereby providing a discharge opening for fasteners contained within the drum. Adjustably secured to the wall. oi the drum as by set-screws 1.82 is an apron 183 extending downwardly into said discharge opening and being provided with a portion 18% deflected substantially ht angles to the body-portion of the on. Secured upon the edge of the plate at the depressed portion thereof and adjacent the discharge opening in the drum are a pair of brackets 185, said brackets serving to removably position a supporting n'ieinber 1.86, slid member being provided itli a projecting fin 187 (see earrving at its free end a gate-inernber 188. lVhile the supporting member 186, the fin and the gate-member are herein shown as integral it is clearly evident to those skilled in the art that these several. devices may within the scope of the invention be formed as separate parts suitably secured together and it is also evident that while the support 186 shown as formed separately from the brackets 185 the same might be integrally united therewith. i

The gate-member 188.presents two outstanding flanges 189, such flanges serving as the inner wall or channels 1 0 formed between same and the inner wall of the :-;upport 186 Within the flanges 189 are cut a series 01 pairsof grooves or slots 191, greet s or slots serving to permit the passage of flanged fasteners from. the hop per into the channels 190, these grooves or channels except such fasteners be in a predetermined position with respect thereto.

Fasteners such as employed in the present machine and therein described as eyelets are "med as short tube having an outwardly turnedfiange at one end thereof. it will be noted from inspection of Fig. 18

that the supporting member 186 is so located with respect to die plate .157 and the outwardly turned portion of the apron 184 as poor ot the drum by gradual in being or such shapeas not to per uni the passage tnerethrough of fasteners" mally contact with the base-plate, are re lieved of such contact in passing said area, and at the same time present their free extremities substantially centrally or": the gatemember 188, this providing for a uniform action 01'? the brush at both the upper and lower series of grooves 191 and at the same time securing freedom of movement of the fasteners reason oi the additional space adjacent the discharge opening provided by the depressed area in the base plate of this point. It will now be appreciated that upon presentation of a series of faStQHGTS to the gate-member by the rotation of the agitat ing brush such fasteners. as are presented with their flanges in position to enter the space between the top and bottom of the gate-member and the adjacent Walls of the hopper may pass through the grooves in the gate-member and into the channels 190. As will be clearly seen from this construction the fasteners permitted to enter the channels 190 form two separate series having their tubular portions opposed toeach other, the flangedends of the fasteners being directed away from each other.

In taste er setting machines aspreviously constructed various methods, of presenting fasteners in proper position to be operated on by opposed sets of fastener-setting means have been employed among which may be mentioned the use of hopper devices provided with independent receptacles for fasteners each being adapted to supply araceway, he use of single chambered drums having for separating the fasteners into two substantially independent masses with separate actuating devices therefor and with separate discharge openings,and the use of a single chambered drum having a single discharge opening and with means for reversing a portion of the fasteners after they have left said discharge opening.

it will be noted that all of these constructions complication oi parts is necesy and that with devices of this character 3 is necessary to employ raceways having more or less abrupt changes er curvature, or to employ reversing means between the hopper and the raceway. As is WGlllUlO'WIl to those skilled in the art, all such abrupt changes in curvature of the raceways and the employment of roversingnieans therein are fruitful sources of trouble in the practical, operation elf machines of this type, 1'6 a sulting in irregular iced oi fasteners and occasioning frequent stoppage of the machine with consequent annoyance to the operator and in the present machine the endeavor has been to avoid all such sources oi delay in operation by the employment of raceways having only a very gradual change 01? direction and the elimination ot'all reversing devices bet-ween the hopper and the delivery end of the raceway. The above objections and diiliculties are avoided by the use oil? applicants device wherein the fasteners are discharged directly from the hopper in independent reversed series and wherein such fasteners may he fed directly to two substantially like raceways which may be of the-most simple form and construction necessary to lead the fasteners from their point of egress to the setting dc vice. In the arrangement shown, the gatemember 188 provided with a series of grooves of agiven width especially adapted to permit the passage oi" a predetermined type of fastener although fasteners of rather widely varying sizes may be employed therein successfully, but by reason of the fact that the gate-member is rei'novably sup ported it is evident that other members having grooves of different sizes may be provided with the machine thereby to permit the employment therewith of fasteners oi? any desired size or type. i

As herein shown'the plate 157 has attached thereto or integral therewith, at a point adjacent the discharge opening 181, tho-basemember 192 of the lower 01: a pair of raceways said base-member being connected to said plate by means of a screw 193 or other suitable means. The base-member 192 is herein shown as in the form of a flat plate extending downwardly with a gradual ourvature from. its support to "aid the delivery point for the fasteners. Cooperating with this base-plate and suitably spaced therefrom by means such as washers 19-11 are a pair of: guide-plates 195, these plates being spaced apart to provide a channel continuous with. the lower channel. 190 of the supporting .i'nember 180 thereby to provide guiding means for the tubular portions of fasteners moving in said clninnel, the flanges thereof sliding upon the base-plate192 and extending into the space between said baseplate and the guiding plates 195. The guide ing plates are secured to the base plate by suitable connections such as screws 196 and by removing these screws, guiding plates of various widths may be attached to the base-plate. Washers of diiicrent thicknesses may also be employed between said plates thus enabling the raceway to be adapted for use with fasteners of greatly diiferent sizes. Secured to the base-plate 192 is a bracket 197 said bracket being provided with a threaded opening 198 havingengaging therein the clamping screw 199. The lower or discharge end of the raceway is provided with a resilient retaining finger of usual construction and arrangement. Cooperat ing with said. bracket 197 is a second bracket 200 said bracket having a slot therein adapted to take over the screw 199 thereby providing for adjustment of bracket 200 with respect to bracket 197. The bracket 200 serves as a supporting means tor-"the baseplate 201 of the upper raceway, said upper raceway being of substantially the same construction as the lower raceway, it there fore being unnecessary to describe the same in detail it being noted, however, that the parts thereof are relatively reversed with re spect to corresponding parts of the lower race. By the above construction the receiving end of the upper raceway may be adjusted to bring it into alignment with the upper raceway or channel of the suppi'irting member 186 such adjustment being desira-b at times due to interchange of such supporting members 180 for use with differentsizes of fasteners. WVhile means has been herein described for adjusting the races for use with fasteners: of varying sizes it also within the scope of the present invention 199,499, filed October 31, 1917 by George V].

Reciprocating means for mceways.

As in this machine the punch descends to punching position in a single operation and has no lateral movement at that time and as it is desirable that the punch pick off a fastener from the delivery end of the raceway in its downward movement it is necessary that the raceway be moved out of the path of the punch during the punching operation of the latter, and the following means has been devised whereby the delivery ends of the raceways may be reciprocated in proper time with the operation of the punch.

Mountedin a suitable opening 202 formed in the frame member 1 is an adjustable flanged bearing sleeve 203, reference being bad to 90f the drawings for specific disclosure of this mechanism, the flange 209 of said bearing sleeve being provided as shown in Fig. 2 with a slot 20 1- and with a screw 205 passing through said slot and entering the bracket member 1. Mounted for rotation within said adjustable sleeve is a shaft 206 provided at its outer end with a fixed crankarm 207, a spring 208 having one end bearing against said arm and. the

other end attached. to fiange209 serving to normally turn said shaft in a clockwise direction as viewed in Fig. 2 t0 the extent permitted by suitable stop devices to be described. Within the outer face of the flange 209 forming a portion of the sleeve 203 is formed a slot 210 said slot being provided at each of its ends with depressions 211 212- extending inwardly below the bottom of said slot. Passing through the arm 20'? and having a suitable bearing therein is a springpressed pin 213having a knurled knob or handle 214- at its outer end and. being prothereby iermittin'g the pin 213 to enter one or the other ot the depressions 211 212 in which latter position the arm 20'!- is locked to the flange 209 thus rendering the shaft 206 innnovable, and that upon retracting pin 213 and turning the same until pin .216

enters the shallow slot the pin213 may be locked in retracted position, thus permitting tree swingingof arm 207 within the limits of slot 210 by means to be described. Upon the inner end of the shaft 206 is fixed a crank-arm 217. At 218 see 1 and 9, is

indicated a yoke member having universal connection of any desirable character with a bracket inen'iber 219, the latter serving a support for the delivery ends of the raceway In the embodiment herein shown the universal connection between the above parts comprises two pivotal. members 220 and 221 having a link inen'iber 222 connecting the same, the members 220 and 221 being respec tivcly mounted in yoke 218 and the bracket 21?), it being evident, however, that equivalent connections are fully within the scope of this invention. Pivot-ed to theinner end of the yoke member 218 at the points 228 and 22 1 is a guide-member 225 said guidemember having suitable guiding surfaces for a slide-block 226, the latter being provided with a bearing 2-27 for the crank pin 19 heretofore described as extending from the end of the drive shaft let. Pivotally mount-- ed upon the outer-surface oii said ,e uiding member 225 at the point 228 is a vibratory link 229. said link having pivotal connection at the point 230 with the aforesaid cranlo arm 217. lf'i ed to the sleeve 203 as by means ofa screw 231 is astop member 232 hearing at end upon the inding member thereby serving to hold the same in proper relation to the slide-block 226 and the eccentric-pin 19. At the point i 33, see Fig. formed a flat seat which may be integral with the machine frame or attached thereto, such seat being adapted to form a slide-way for the raceway supporting member 219, suitable means such as the bracket-arm 236 see Fig.16 being provided -for properly positioninp said member 212 with relation to the seat but permitting limited lateral. movement thereof. Said member 219 is herein shown as in'tbe form of: a yoke having a lower arm integral therewith, said arm having: a surface for engaging the seat 233 as above noted, and an upper arm 235 adjustably secured thereto asby means of a slot 236 and set-screw 237, see Fig. 17. Secured to the lower arm 23 1 either directly or by the use of an intervening bracket is the base'member 192 of the lower race and secured to the lower side of the upper arm 235 the base member 201 of the upper raceway it being evident from this construction that by adjustment of thearm 235 with respect to the arm the position 01 the delivery end of the upper raceway in a direction from front to rear of the machine may be varied with respect to the lower raceway. Attached to the arm 207 at the point 238 is a suitable connection 239, herein shown as a chain whereby the operatormay turn the shaft 206 in a counterclockwise direo' tion as seen in Fig. 2. that is to say, against the tension of the spring 208. In the normal operation of the machine the pin 213 will be retracted from the depressions 211. 212,

the pro'ectine: part 215 of said in travellinm l i l 1,

over the bottom of the slot 2 10 upon actuation. oi? the chain 239 by the operator, the

spring 208, however, normally j holding the pin in engagement with the end 212 of the slot thereby holding the crank 217 in substantially the position shown in Fig.

Upon actuation oi the drive shaftit will seen that the eccentric pin 19 will move the block 226 in a circular path, such movement 3y reason of the connections comprismg the relatively hired crank 217 and the link 229 resulting; in a reciprocating movement of the guide-member 225 and therewith oi": the 1 yoke 219 and its connected raceways to produce a forward and rearward movement of the latter upon each rotation of the drive shaft, the eccentric pin and the cam 79 being so relatively positioned as to produce proper timing relation of the punching operation and the raceway movement. It will now be noted that by movement ot" the arm 207 through the chain 239 as by means of a treadle or other suitable device the shaft 206 will be rocked in a direction to cause the link 229 to approach a position of parallelism with crank 21?, such movement act ing to retract the yoke member 218 and therewith the raceway, subsequent motion of the eccentric-pin 19 thus failing to sent the raceway in position for delivery of fasteners therefrom to the punchi It w ill be observed that the guide 225 constitutes a follower for the actuating element afforded by tnecranl pin 19, the slide-block226 be. interposed to insure ample bearing contact between the contiguous parts, while utter-ding a sliding connection between the two to enable the follower to move transversely of and relatively to the cranloelement; also that-the pin 280 constitutes a normally stationary fulcrum for the vibratory link 229 but shift-able into different angular relaions with the path of movement of the crank-element 19. By ref erence to at and 9, it will be observed that the guide-member or follower 225 performs uniform up-and-down movements equal to the diameter of the circular path of movement of the crank-um 19. and that the p. -t

between its dotted line position represented in said figure and a position corresponding with the axis of the alined shafts 1d: and 206. It therefore results that in the upper ex treme position of the crank-pin 19 the link 229 in its upper position draws the follower element 225 to the left and thereby jogs the eyelet llCGSlIltO register with the punch elements; while in the extreme lower position of the cranlopin 19 the link assumes a position overlying the arm 217 and with its movable end at the axis of the shaft 14. j

The shifting of the arm 217, and with it the fulcrum-pin 230 upwardly concentrically with the shafts i l and 206 to a position intermediate said shafts and the pivotal pin 221 causes the outer or free end of the yoke attached to the follower-member 225 to swing: in a i are which is substantially vertis cal. of which the lower end is still coincident with the axis of the shafts 214i and 206 and the upper end is above the same. It is thus obvious that by shifting the fulcrum-pin 280 the throw of the eyelet-raceways toward and from the centering elements may be adjusted so as to bring their. respective eyelets into exact register Wi'tl'l the punch, whi e their retracted. positions are invariably at the same fixed point, the shift of the fulcrum thus varying the amplitude of the jogging move-' ments to and from said fixed position. If itbe desired at any time in the operation of the machine to employ, the same merely as a punching device, the arm 207 after be inn depressed as above described, may be locked in the latter position by releasing the pin213 and allowing the same to set itself in the depression2l1 thereby permanently holding the raceway out of operative relation with the punches during the operation of the machine, As at times it may be ,(lQSllZllGlfi toreinove the raceways' from ready controlby the operator the other deal connection of the link 229 thereto performs equalup-and-down movements pression 212 has been provided, interlocking engagement with which by the pin 213 insures the normal cooperation in each eye letting cyclebetween the race ivayand the punching device.

By adjustment of the bearing member 203 by means of the screw 205, the initial position of the yoke member 219 and therewith of the lower raceway, nay be varied, the connections described thus permitting independent adjustment of the upper and lower raceways and also simultaneous adjustment in a direction toward and from the fastener setting tools, lateral adjustment of the races being also provided by the adjustable mounting of the hopper, as above described, such adjustments being desirable and in many cases necessary for the proper operation of the machine.

Pressei foot and wofiwsuppmt.

Fi edly secured in any suitable manner to the frame of the machine is a work-support 24.0, 4 and 10) said support having upper and lower surfaces for engaging the we 1;, the main portion of said work support located in a position at one side of ll and being provided with a forwardly and laterally extending member 241 forming an auxiliary suport at the front of the anvil. Adjustably supported upon said uni -support is an edge-gauge 2 12 said gauge act rig in the "usual manner to guide the inner edge of the work while it is pre i to the operating tools.

ne comprises a saddle 2-l2' adaptupon the rearwardly extending of work-support 2 l0 and a pair oil? g r. apart arms 242 having forwardly and laterally extending lips 2&3 which are preferably integral with said arms although this not necessary. Between said arms an open-ended slot 245 adapted to receive and to permit sidewise movement thereinof the anvil member 130. The member 242 serves as edge-guides for the material in the usual. manner while the overhanging lips act to retain the material upon the work support against displacement by the punch in its retracting stroke. It will be noted that those lips extend aconsiderable distance'forward of the position of punching in the direction of feed, additional means to be hereinafter described acting on the opposite side A l to hold the work against the support at this point. The saddle 24.2 is mounted to slide on EHO and is provided with a slot 242*. In the underside of leg 2&0 is a recess 24H adapted to receive and prevent the turning therein of a hexagonal nut 240. Passing through slot240 and through a suitable opening in'leg 240 is a bolt having its head in the forn'; of a thumb-lever 240, said bolt engaging nut 240". By properly positioning nut the punching position v inthe permitting-of a line adjustment of the tlghtening action of bolt 24H)". B

the above arrangement the distance of the line of fasteners from the edge of the work may be adjusted with the greatest ease, no tools being necessary to accomplish the desired result.

At the point 24:6, see Fig. 1, is indicated a bracket acting as a support for an auxiliary work-guide 24:7, such guide being desirable when operating upon certain classes of work.

Cooperating with. the upper and lower surfaces of the work-support is a pair of presser-feet, said presser-feet being duplicates and therefore only one of the same will be described, Referring now to Fig. 4, reference character 2&7 indicates any suitable sup-. port mounted upon the frame, said support having projecting therefrom a guide pin 2-18. 249 is a presser-foot device, said device comprising a sleeve 250 and a foot portion 251., said sleeve portion being provided with. a lug 250 having an open ended slot 250* adapted to take over said guide pin 241:8 whereby the presser-foot is supported for sliding and rocking movements. As will be noted in the View of the lower presserfoot, Fig. 4-, the forward portion presents a surface curved from front to rear and is substantially wedge-shaped in section, the thicker portion. thereof being to the rear, thus leaving a flaring groove or notch 251 between the forward end of the presser-foot and the work-support providing for ready insertion of the work therebetween. Slidable within the sleeve 250 is a second sleeve 252, said sleeve being threaded at its outer endfor engagement with an adjusting screw 253. Located within the inner sleeve 252 and bearing upon the inner surface of the presser-foot is a spring 254 said spring bearing at its opposite end upon the adjusting screw the latter serving to adj ustably tension the spring. Surrounding the sleeve 252 and fixed thereto near its outer end is a collar 255, said collar being provided with alug 256 having a bearing therein loosely embracing a pin 257, said pin being suitably headed as shown at 258 and having finedenln the initial position of tie parts with the haminenlevers 72 and 73 in their fully retracted position. the springs as may be placed under initial tension by the adjusting screws 253, such tension serving to produce pressure Oll'dGSil'Qd amount between the presser-foot surface and the work-support. Upon movement of the hammer-levers for producing operation of the fastener setting devices, the collar 255 will be moved therewith in a direction to compress the spring gagement with one of the arms of the lever 25% and thereby substantially increase the pressure of the presser-foot upon the material held between the same and. the worksupport, and such increasing pressure will occur at the moment of operation of the fastener setting tools, thus serving to hold the work in proper relation thereto and at the proper time. I i

While in machines of the prior art, it has been. common to place the work under (0111- pression during the operation ofthe punching or setting tools it has been common also to entirely release such pressure during the feeding movement. This, how-ever, is found.

to be undesirable as the work is left at such t1 me without any means of control other than such as may be exerted by the operator.

This invention secksto avoid the zlbOTG dithculty by providing at alltimes a certain pressure between the presser-foot and the work forholding the work between the presserfoot and the work-support, the work however, at the time of punching or setting being held with a very substantial pressure against accidental displacement.

By reason of the location of the presserfoot to the right of the operating tools as shown in Fig. 1 and the extension of the work-gauge 242 having the overhanging lips 243 in a position to the rear of the operating tools the work is held at two points from any lifting action of the punch in retracting, thus providing means not usually found in the prior art for retaining the work in proper operative relation to the ninchin devices. lt may be noted that by reason or the pivotal .movement of the n'esser-foot about the pin 2&8, which movement takes place at every stroke the hammer-members, due to" the connections above described,

and by reason of the wedge-shape of the presser-foot 251, the work engagedby said presser-foot is forcibly fed rearwardly to-. ward the work-gauge, this feeding action taking place at each cycle of operation of themachinc, thus serving to hold the work against the work-gauge in positive manner. it is recognized that structures of the prior art have been devised ha wing at tendemqv upon lateral movement of the work over the work support to cause a feeding movement of the same toward the edge-gauge but prior to the present ii-ivention no positive mechanically operated means has been provided in machines of this character for prm'lucing a feeding movement of the work in two directions at right angles to each other that is to say, a movement laterally of the wmrk-support fOIfQGdilig me work for the fastener setting operation and a second feedin movement of the work in the direction from front to rear for holding the same against the work-gauge.

Having thus indicated the nature of the invention, and having specifically described iii
