, i 7 Application filed August 5, 1914. Serial No. 855,185.

To all whom it may concern Be it known that I, PERLEY R. GLASS, a citizen of the United States, residing at Brookline, in the county of Norfolk and Commonwealth of Massachusetts, have invented certain Improvements in Fastener- Setting'Machines of whichthe following description, in connection with the accompanying drawings, is a specificatiomjlike referencecharacters on the drawings indicating like parts in the several figures.

This invention relates to improvements in machines for setting fasteners in sheet material, and more particularly to machines for inserting such fasteners .as eyelets or lacing hooks in the uppers of boots and shoes.

In setting eyelets of various sizes and in difi'erent styles of boots and shoes a wide variation in spacing is demanded; for ex ample, small eyelets are often set in womens shoes with a spacing of one half inchor less,

while large eyelets are often set in heavy boots with a spacing as wide as two inches. The feeding mechanism of eyelet setting machines as heretofore constructed has operated at a uniform speed regardless of the extent of the feeding steps, and consequently the linear speed of the Work through the machine has varied very greatly. This has frequently resulted in wasted time in the former case, and in inconvenience to the operator and work of poor quality in the latter case, for it has been impractical to vary the speed of the machine in accordance with. the setting of the feeding mechanism.

In the case of a. machine running at the proper speed for eyelets set With a wide spacing, the setting of eyelets with a close spacing has resulted in a very slow travel.

of the work through the machine, While, on

' the other hand, in the case of a machine operating at the proper relatively high speed for eyelets set with a close spacing, an unmanageable speed of the work has resulted when the spacingmechanism has been adjusted for wide spacing.

With these' conditions in view, an important feature of the present invention consists broadly in variable or change speed mechanism and adjustable work feeding means controllably related in respect to its adjustment, to said mechanism. The em- Specification of Letters Patent.

IASTENER-SET'IING MAGHIN E.

ployment of such mechanism enables the work to be passed through the machine at a substantially uniform linear speed regardless of the spacing of the fasteners or eyelets; for example, if'two-speed mechanism were arranged to operate the machine at either 600 or 350 revolutions per minute a substantially uniform movement of the work through the machine would result when setting eyelets with a three-quarter inch spaclng at the rate of 600 per minute, or, when setting eyelet-s with a spacing of one and onequarter inches atthe rate of 350 per minute. i In this connection another feature of the invention consists in means for locking the feed controlling device against movement to position corresponding 'to a wide spacing so long as the change speed mechanism is arthe speed controlling device will be prevented from movement to its position for high speed so long as the spacing mechanism is set for wide spacing; Such construction safeguards both the machine and the operator against the results of the unexpected operation of the machine at excessive speed. 1 1

Other features of the invention consist in the novel construction and arrangementof themoving parts, whereby inertia is reduced to a minimum and operation of the machine at a highspeed together with positive and accurate starting and stopping, rendered possible. These constructional features will be pointed out in detail hereinafter, but may be grouped for convenience as follows: (1) mechanism for operating the lower or eyelet carrying set, (2) mechanism foiraising and lowering the upsetting and punching tool, (3) mechanism for transversely moving one ofthe tools for feeding the work, (-l) raceway operating mechanism, (5) presser foot operating mechanism. and (6) gage mechanism. \Vhile each of these several features is believed to possess many novel characteristics their cooperative combination also involves subject matter of invention. 1

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

Fig. 9 is a view in perspective of the gage mechanism."

The machine frame 2 is suitably shaped to support the moving parts of the machine and is provided with journals for the main shaft 4 carrying at one end a driving pulley 3. r A, clutch mechanism-of well known type is interposed between the pulley 3 and the mainshaft and the starting and stopping of the machine is controlled through this mechanism.

Lower setting tool-The lower portion of theframe is provided with vertical guidehaving adjustably mounted in its upper end the lower or eyelet carrying set 9. Secured to the plunger 6 is a split collar 8 having ears on its rear side through which extends a clamping bolt. This bolt is extended beyond the ears of the split collar and forms the journal for a block 10 which is held in place by a washer 12 shown in Fig. The block 10is received between the jaws of a forked lever 14 journaled between its ends upon a shaft 16 which is suitably supported-by the machine frame. The lever 14 is oscillated by a connection with a crank fast on the main shaft, 4.as shown in Fig. 5. This crank has pivotally secured to its outer end a follower comprising a block 20 of which the upper and lower surfaces are curved to slide in av curved slot 18 formed in the rear end of the lever 14:.

From the mechanism thus far described it will be apparent that the rotation of the main shaft 4: imparts vertical reciprocations to theeyelet carrying set 9. The curvature of the slot 18 in the lever 14 is on a radius slightly longer than the length of the crank ways in which reciprocates the plunger 6' end of the lever 14 very rapidly, and this motion efiects a rapid elevation of the eyelet carrying set 9 after the raceway has been withdrawn. In the next halfrevolution of the shaft the eyelet carrying set is lowered, at first rapidly and then more slowly, and the parts are returned to their initial positions, as shown in Fig. 5.

The construction of the mechanism for op erating the eyelet carrying set is particularly advantageous in that it affords simple and positively acting means for moving the set in the desired manner, that is to say slowly upwardly until an eyelet has been delivered from the raceway, then rapidly upwardly, to effect the clenching operation and then downwardly at high speed so that the work is disengaged and left free to be advanced at the earliest possible moment in the cycle of the machine. I I i The split clamping collar 8 affords facility for making a preliminary adjustment of the path of movement of the setting tool 9, but in order to enable the operator to make the adjustments necessary from time to timein running the machine an. adjusting bolt .11 is threaded into the bottom of the plunger 6 and by turning this bolt the position of the settingtool in its carrying plunger may be varied.

U pper setting t00Z.-Theframe 2 is formed with an overhanging portion having two sets of horizontal bearings, one for the upper rod 26 which is held stationary by screws 30, and the other for the lower rod 28 which is arranged to slide freelyin its bearings. The horizontal rods 26 and 28 carry the feed frame 32. At its upper end the feed frame is free to slide upon the rod 26 while at its lower end it is secured to the rod 28 and carries the latter with it in its transverse movements for feeding the work. The feed frame 32 is provided with vertical guideways for the plunger 34: which carries 34 and rests upon an adjustable nut 38. At

either side ofthe collar are pivoted links 42 which constitute the lower member of a ,tionary rod 20' and connecting the knuckle of the toggle. with the forward end of alinle 18., The link 48 has formed in it an mclmed slot 50 through which loosely extendsth'e stationary pin The slot 50 acts 7 has a guide for theend of the link 48 and i is reciprocated' from front to rear, keeping its end substantially opposite to the knuckle joint of the toggle as the latter is straightened andbroken. The link 18 is connected at its rear end to the upper end of a vertically disposed cam lever 51. as shown in Fig. 7. The lever 54 is journaled upon a stationary pin 56 and at'its lower end has two forked arms upon the inner surfaces of which are secured hardened bearing pieces. A cam 58-secured to the shaft at acts upon these bearingpieces and thus-oscillates the lever. i

The link 48 is so connected with the toggleet2- ll as to permit the relative transverse movement to take place which is necessary in the feeding operation. T o this end a it has rigidly clamped in its forward end a transversely disposed rod 13 upon which slide the rear ends of the two bell crank levers 4+1. The' forward end of the link 48 is held against transverse movement by heads formed on the pin This feature is of importance in that it prevents all binding 3 or cramping ofthe levers all upon the rod 43, a diliiculty which would occurif the link 48 were permitted'to become angularly displa llorl: feeding m e071abisque-Transverse I movement is imparted to the tool 40 for feeding the work by mechanism "which will now a be described. The frameB-Z is provided at its lower end with a rearwardly extending arm to which is pivotally secured the block 80. The block 80 is received between'thewsjof a forked arm 82 journaled upon a stationaryvertical shaft 86.

'At its lower end the arm ways for movement from front torea'r. The frame 98 has extending from its lower side a-pair of aws fitted with hardened bearing pieces which engage a cam 1 00 upon. the main shaft l. The path of the point of pivotal connectionbetween the links 92 and 94 isguided by a pair of radius links 96 secured to a sleeve 102 journaled upon a vertical pin 1011 which is'set in the under side of a pivoted plate 106. The plate 106 is arranged to turn about a pivot pin 108, as shown in Fig. 8, and s provided with a spacing handle 109 which swings over a graduated spacing plate 110. The plate 106has an upwardly extending boss to which is secured a spring 112 fast at its other 'end to a pin projecting from the machine frame. The spring holds the spacing lever 109 in an 1n1t1al position against 0ne of two stops 114.

Through the connections above described the uniform reciprocation of the yoke frame 98 is transmitted to the feed frame 32 and so long as the spacing lever 109 remains in the same position the extent of feeding movement will be uniform. The extent of the feed, and consequently the spacing of the To in-' is transmitted'to the sleeve 88. \Vhen the spacing handle 109 is in the full line position shown in Fig. 8 the oscillation of the sleeve 88 is represented by the angle A.

"lVhen the spacing handle is moved to the dotted line position shown in Fig. 8 the oscillation of the sleeve 88 is increased to the angle B. A

Raceway medianism.Eyelets. are supplied to the spindle of the eyelet carrying set 9'by the raceway 120 removably earned by the bracket 122 pivotally mounted upon a shaft 124; set in the machine frame \Vhen the eyelet carrying set is in its initial "position, the delivering end of the raceway holds itsendmost eyelet in a position slightly above and in the rear of the end of thespin- When the machine'is started the racewayjis first' oscillated so as to carry the eye let into position to be cngagedby the spindle,

whereupim the delivery and of the raceway is moved rearwardly into an inoperative position, thus allowing thepassage of the eyelet carrying set. i 1

Movement of the raceway is effectedv from a craiik-13tl on the end of the mainshaft 4.

The crank 130""i's connected through a short 132 is connected through a universal joint to an adjustable pitman 130 wh ch, at its forvertical pin set in the machine frame. The

other arm of the bell crank lever 128 is connected through a short link 126 to a projection upon the raceway bracket 122.

It will be noted thatthe end of the raceway is moved rearwardly from its del-ivering position instead of outwardly as heretofore. This arrangement is particularly advantage- 011s in that it obviates all possibility of injury to theoperator, there being no possibility of accidentally reaching the space between the end of the raceway and the machine frame.

The raceway itself carries at its upper end a hopper 121 of the usual construction, and this and the raceway are removably held in place on the bracket 122 by a hand nut 119 which may be readily loosened whenever it is desired to changefrom one style of eyelet to another. The hopper is provided with an agitator of the usual form, which is driven by the pulley 123 through a belt running about a pulley formed on a cap 125 located on the right hand end of the main shaft 4, as seen in Fig. 2. The cap 125 may be clutched to or unclutched from the loose driving pulley 3 by means of a shifting arm,

127 pivotally mounted on a stationary casing 129.

The machine is provided with a work table 71 ofsuitable shape to accommodate the work to be eyeleted. The table is perforated to permit the passage of the lower setting die, and slotted to receive aicutting bed or block 69 with which the punching end of the tool 40' coiiperates in performing the work.

Presser foot mechanism.-A presser foot 72 is arranged to clamp the work on the work table between the feeding operations of the machine. The presser foot is adjustably clamped to the upper end of a ver-v tical rod 7 0, to which is secured a block 68 carrying a roller 66, by which the presser foot is intermittently elevated A compression spring resting upon .the block 68 holds the presser foot normally in clamping position with the roller 66 resting upon the periphery of an oscillatory cam platej64, best shown in Fig. 7. The cam plate 64 is mounted to oscillate about a horizontal axis, and is actuated by the movement of the cam lever 54 which, it will berememberedmctuates also the togglemechanism of the upsetting tool. One jaw of the cam lever 54 is provided with an extension which is connected to the cam plate 64 through a rod 62 having a split clamp at each end. It will be seen that when the upper end of the cam le- -ver 54 is thrown forwardly to depress the tool 40 the extension 60 is movedrearwardly and the-cam plate 64 turned to such position that the roller 66 and the presser foot 70 through bearings in the machine frame into engagement 'with the forward end of a 'treadle actuated lever 74 which may be elevated through the chain 76when it is desired-to raise the presser foot to permit the presentation of work to the machine. To; prevent the presser foot from being dish.

placed angularly, a parallel pin is con nected to the bar 70, and by sliding in a pole in the ,frame prevents twisting of the Gage mechanism.1n order to determine the spread of the eyelets or their distance from the edge of the lacing slit, a gage 160 is arranged at a point in'the rear of the cutting bed 69. The gage 160 is adjustably secured to the end of a gage carrying arm 162 which is pivotally mounted at the right hand end of the work table for movement from front to rear. The pivot pin 164 of the gage carrying arm extends through the table 71 and is threaded at its lower end to receive a nut having a clamping handle 166. By this construction a convenient means is afforded for adjusting the gage 160 into any desired position. It may be moved transversely on clamping nut and swinging'the gage carry' ing arm to the desired position where it may be locked by a slight movement of the handle 166.

Speed controlling mohaniam.-Below the" correspond with the opposite surfaces ofa fast clutch member 148 splined to the countershaft 140. A clutch shifting lever 150 is disposed within convenient reach of the-operator, and by it the clutch'member 148 may be connected to either one of the driven pulleys 144 or 146, so that the machine will be operated at a greater or lesser speed in accordance with the requirement of the work in hand. I r

The transmission mechanism above described is so related to the spacing mechanism of the machine that operation at high speed is permitted only when'the spacing mechanism is set for a. short; feed, operation at low speed being desirable when the ma chine is set for a wide spacing. To this end the clutch controlling lever is provided with an inclined cam surface 152 so disposed work.

riphery with a tooth which, in theposition of the parts illustrated, stands at one side of the upper'end of the rod 154, but which, When the spacing lever 109 is moved to a position corresponding to a wide spacing of the machine, stands over the end of the rod 154 and locks it against vertical movement. with the parts in the positions shown in v Fig. 3 the spacing lever 109 is set for a feed clutch controlling handle 150 is free to be of. about three-quarters of an inch, and the moved into either position, so that the machine maybe run at a high speed. When the spacing handle 109 has been moved forwardly to increase the feed of the machine the rod 154, as above explained, prevents the movement of the clutch controlling lever 150 toward the right, and so prevents the machine from being run at high speed with a wide spacing. Moreover, if the clutch c0ntrolling lever 150 is moved to engage the smaller or high speed pulley 144 while the spacing lever 109 is in a position corresponding to a short feed, the end of the rod 154 will stand in the path of the tooth on the spacing late 106, and so prevent the spacing hanc le 109 from being moved forwardly to increase the. feed of the machine.

The operation of the machine which, it is believed, will be readily understood from the foregoing description is briefly as follows :.-The position of the gage- 160 and the feed of the machine are initially established, and the speed of the machine is appropriately regulated by the setting ofthe clutch controlling lever 150. The work to be eycleted is then presented upon the work table with the point at which the first eyelet is to be set.located under the tool 40 which in tially occupies its extreme right hand positiona The machine is then started, whereupon the toggle 4244 is straightened, de-

pressing the tool 40 .and perforating the The knuckle joint of the toggle 1s carried slightly past its central position so that the tool 40 is elevated sufficiently to carry its end out of engagement with the cutting bed,- and relieve the pressure of the machine;

The feedframe 32 is then moved toward the left carrying the tool 40- into alinementfwith the eyelet-carrying set Qwhich takes an eyelet from the. raceway and then moves upwardly to effect theinserting and clenching j operations.

Immediately .thereafter the toggle 42 44 is broken and the tool 40 elevated out of engagement with the "-clenched eyelet, the work meanwhile being clamped by the lpre$er foot wh ch holds 1t stationary while Tthdsettmg devices are returned to their" in lei. positions.
