'l '0 all whom it may concern.

Be it known that I, FREDERICK H; 'PERRY,

a citizen of the United States,-residing vat Beverly, in the county ofEssex and Com: monwealth of Massachusetts, have invented certain Improvements in Machines for Inserting Fastenings, of which the following word fastenings being hereinafter used,.

for brevity and convenience, to designate and include any and all materialsand devices which may be used for the purposes named. Machines of this type are used extensively in the manufacture of shoes for attaching the outersole of .a shoe to its innersole or for ornamenting the tread face of the heel or sole. It has been the practice heretofore to use such machines to insert one continuous row of fastenings in the tread face of the heel of a shoe in a lineconfornr. ing to the outline of the heel, and a second row of fastenings inside of the firstextending for a portion of the length of theifirst row. The means for controlling the insertion of the fastenings of the inside row,

however, was manually operated, and because of this the inside row of one shoe of a pair would often contain more or less fastenings than the corresponding row in the other shoe of the pair, and would also often occupy a different position in the surface of the heel, on account of the inability of the operator to commence and discontinue the insertion of the fastenings of the inside row at just the proper point in the cycle of operations of the machine. This-lack of uniformity in the inside rows detracted greatly from the appearance-of the pair of shoes when finished.

One important feature of the invention consists in automatic means for inserting fastenings in a predetermined design, pref? erably in combination with means forvarying the operation of the machine to change the design in which the fastenings are inserted.

Another feature of the invention is the combination of means for inserting a plurality of different kinds or rows of fastenings with means for controlling automatically the insertion of fastenings of one kind, or the fastenings in one row, without affecting the insertion of fastenings of a different kind or the fastenings in a different row..

A further feature of the invention consists in automatic means in a machine of the class mentioned for discontinuing the insertion of fastenings of one kind or in a certain row while the machine continues in operation,-either to feed the stock, as usual, or, in addition, to insert fastenings of other kinds or in different rows. Preferably there is employed, also, means for inserting a certain number of fastenings, then discontinuing .the insertion'of fastenings for a certain number of operations of the machine and. thereafter resuming the. insertion of fastenings.

A further feature of the invention consists in means for varying the time of operation of the means, mentioned above, which causes the insertion of the fastenings to be discontinued automatically for a certain number of operationsand thereafter to be resumed. 7

Other features of the invention will be hereinafter pointed out.

The preferred form of the invention is herein shown as embodied in a machine for forming Vfastenings from continuous material, such, for example, as wire, and inserting them into stock, said machine being adapted to operateupon a plurality of strands of wire, so that a plurality of fastenings may be inserted simultaneously. Said machine comprises automatic means for causing the feeding of one strand of wire to be discontinued for a certain number of operations of the machine and thereafter resumed without affecting the operation of feeding the other strand or strands of wire. The machine also comprises means under control of the operator for varying the time of operation of said automatic means so that the sequence in which the fastenings are inserted may be varied. Manually-operated means is also provided for rendering said automatic means inoperative while other elements of the machine continue in operation.

The machine has mechanism for feeding a plurality of strands of wire into position to on the edge of the stock.

A movable dial or pattern device, having adjustable controlling pins, is provided for governing the operation of the wire-feeding mechanism for one strand of wire, and the position and arrangement of said controlling pins may be changed to cause the feeding mechanism to feed said strand at each operation of the machine or intermittingly during the operations of the machine, thereby enabling the fastenings formed from this strand to be inserted in any sequence to produce a predetermined design. Means is provided for restoring the dial to starting position whenever the machine is stopped, so that the same design may be produced repeatedly on difl'erent'pieces of stock, and for enabling the same design to be produced on the heel of either a right or a left shoe, addi tional means is provided for adjusting the dial. Independent means is also provided for causing the 'dial to remain inoperative While the other elements of the machine continue in operation, and when in its inoperative position a controlling pin on said dial can be so adjusted as to cause the feeding mechanism either to act on the wire at each operation of the machine or not at all.

Inthe drawings, Figure 1' is a front elevation of a machine embodying the preferred form of my invention; Fig. 2 is an elevation of the right-hand side of the machine shown in Fig. 1; Fig. 8 is adetail view looking toward the rear of the machine taken on the line 33 of Fig. 2; Fig. 4 is a perspective front view of the dial or pattern device which controls the feeding of one strand of wire and the operating mechanism for said dial; Fig. 5 is a detail plan view partly in section, taken on the line 55 of Fig. 9, showing the wire-feedingmechanism; Fig. 6 is a detail view of one of the pawls which a'ctuates the wire-feeding rolls; Fig. '7 is a sectional view of a portion of the dial or pattern device showing the plunger for moving the controlling pins on the dial into operative position; Fig. 8 is a perspective view of a pair of controlling pins and the spring used for holding them in position; Fig. 9 is a detail view taken on the line 99 of Fig. 2 looking toward the front of the machine; Fig. 10 is a perspective rear view, partly in section, of the dial; Fig. 11 shows some of the designs in which fastenings may be inserted by this machine; and F igs. 12 and 13 show, respectively, the tread faces of the heels of a right and a left shoe.

The invention is herein shown as embodied in a machine of the type shown in United States Patent No. 786,190 to L. A. Casgrain, March 28, 1905, to which reference may be had for the description of parts not herein fully described.

Referring to the drawings, A designates a base or standard which supports the head A that carries the main shaft 0. The coils ofwire and W from which the fastenings are formed are carried by reels 1" and 7 supported by brackets 7" and 1" fastened to the head of the machine, the strands of wire 10 and w being drawn from the centers of said coils and fed into position to be severed to form fastenings, by feed rolls a and a which are mounted on a stud shaft g in the head of the machine, as shown in Figs. 5 and 9. Cooperating with said feed rolls are presser rolls a and a that are mounted ina yoke a adjustably fastened to the head of the machine by a screw a.

As shown in Fig. 5, the feed roll a" is connected to the sleeve or hub of a ratchet wheel a mounted on the stud shaft 3 and adjacent to said roll is the feed roll a connected to a ratchet wheel a which rotates on ball hearings on the sleeve or hub of ratchet wheel a A pawl-carrying sleeve of provided with an arm a carrying a plurality of pawls a and 0a which cooperate, respectively, with the ratchet wheels connected to the feed rolls a and a, is oscillatingly mounted on the stud shaft 3 and said pawl carrier is also provided with a second arm having a roller a that is acted upon by a cam 0; on the cam block a carried by the main shaft. Two pawls are provided for each ratchet wheel, and for insur- .ing that the pawls will remain normally in engagement with the ratchet wheels, each pawl is oscillatingly mounted on the stud 2 fastened to the pawl carrier and is forced toward the ratchet wheels by a spring 3 fastened at one end to the stud and at the other end to the pawl, as shown in Fig. 6. A coiled spring S which at one end is connected to the head of the machine and at its other end to the pin 2 on the pawl carrier, restores said pawl carrier to its normal position after it has been actuated by the cam a. Mounted in the head of the machine, as shown in dotted lines in Fig. 2, is a sleeve 72 in which a shaft is reciprocatingly mounted, said shaft carrying at its forward end a throat 70 provided with openings to receive the strands of wire. After the wire has been fed into said throat the sleeve k is oscillated by means of the lever 70 fastened thereto and actuated from a camroove in cam block (1 to cause the cutting lilade m carried by said sleeve to eeoperate with the stationary cutter m for severing the strands of wire to form fastenings, the shaft being thereafter reciprocated longitudinally of said sleeve by means of lever 70, pivoted at 90 to the head of the machine and actuated by cam. 70, on the main shaft, to place the fastenings in the throat W in alincment with the drivers 6 5 on driver bar Z2 which force the fastenings into the stock clamped between the foot plate a and the horn B.

An awl bar 91 provided with an awl h is reciprocatingly mounted in an oscillating frame 2' and is adapted to feed the stock and also form holes therein to receive the fastenings formed from the strand of wire 20, said awl bar being actuated by an arm 7t fastened to a rockshaft 7L2 pro .*ided with a second arm 7: having a roll that travels in a cam groove in the cam block 72 on the outer end of the main shaft, as shown in Fig. 1. After the awl bar has been moved downwardly to force the awl into the stock, the frame 2' is oscillated to move the awl bar laterally for feeding the stock, and the awl bar is then moved upwardly and the frame oscillated in the opposite direction to restore the awl bar to normal position, the means for oscillating the frame 2' comprising an arm 71 actuated by a cam groove in the cam block a and being fastened to a rockshaft provided with an arm 2' that is connected to the frame 71.

The main shaft carries at its rear end a cam disk C, the periphery of which forms one member of a friction clutch, the cooperating member C of said clutch being continuously driven by a belt (not shown) and being adapted to be moved into and out of engagement with the cam disk C by means of a wech eshaped block C attached to a rod C under control of the operator, said rod being held normally depressed by a spring C to cause the clutch to remain inoperative. The disk C has on its inner face a cam 0, Fig. 8, against which is held a roll 0 on a lover a pivoted on a stud 0* secured to the head of the machine, the lower end of said lever being connected by an adjustable linl: 98 to one member 94 of a brake shoe which embraces the rim of the disk C, the otier member 95 of said brake shoe being fastened to a stationary part of the machine. At the lower end of lever c is a notch which receives a stud 97 projecting from the rod C so that the spring G which holds said rod normally depl 'ssed also operates to hold the roll on leverain engagement with the cam 0. The cam 0 is provided with a groove which receives a roll 0 on a lever e pivoted on a stationary stud e and having connected to its outer end a link 0 that forms part of the mechanism for depressing the horn intermittently for unclamping the stock to rq-rmit it to be fed, as is common in machines 1 of this type.

The inner or right-hand end of lever e is notched at e to be at times engaged by a pawl f pivotally connected to a pawl carrier f oscillatingly mounted on the stud 0 said pawl carrier having a roll f to be acted upon by a species of tappet cam A housing 7' on the pawl carrier receives a spring 3 which, resting at its lower end on a fixed part of the head, maintains the roll f in engagement with the tappet cam F. The pawl f is governed as to its engagement. with the lever e by a pawl controller 7' pivoted to the lever c and having a beveled lug f and a notch on its upper side near its extremity to cooperate with a tooth on the side of the pawl f", a spring 8 pressing the pawl controller toward said tooth, as shown in Fig. 3. hen the rod C is raised to start the machine, the lever c is swung thereby to the right, viewing Fig. 8, so that the tooth on the pawl f will enter the notch of the pawl controller f, the spr ng 5 yielding slightly to allow it to pass over lug f and the continued movement of lever 0 drawing the pawl f from the notch e of the lever 0 So long as the rod C is held elevated to cause the members of the clutch to remain in engagement, it will be impossible for pawl f to engage lever c as the pawl carrier is oscillated back and forth by the tappet cam during the rotation of the main shaft, but when said rod is allowed to descend, the lever 0 will move to the left of Fig. 3 and the pawl. controller f will move the pawl f so that it will engage the notch c in the right-hand end of the lever 6 The tappet cam f is so positioned on the main shaft that it will actuate the pawl carrier f immediately after the pawl. 7 has ongaged the notch in lever and will depress said pawl carrier and rock lever c for lifting the rod 0 and finally depressing the horn far enough to permit the stock to be removed therefrom. The brake is applied at the time the highest part of the tappet cam f engages the roll on the pawl carrier f so that the machine is stopped with the horn depressed, the parts being in the position shown in Fig. 3.

The parts so far s ecifically described and referred to are substantially the same as those shown and described in the patent referred to, except that the machine herein shown is adapted to drive fastenings formed from two strands of wire, and accordingly has been provided with an additional driver 6 and feed roll. a and the throat 71: is provided with an additional opening to receive the strand of wire to.

In order that fastenings may be inserted pattern device 10 which actuates mechanism that causes the feed roll a to become operative or inoperative while the machine continues in operation, whereby the strand of wire 'z.0.'\vill either be fed forward to form a fastening or will not-be acted upon. The dial 10 is rotatably mounted on a stud 12 screwed into a, bracket 14 (Fig. 9) fastened to the head of the machine, and is provided on its periphery with ratchet teeth 11 that are engaged by a pawl 16 pivoted to the arm h that actuates the awl bar, see Figs. 1 and 9, whereby said dial is moved one step forward in the direction of the arrow a in Fig. l at each cycle of operations of the machine, the dial being prevented from retrograde move- -ment by means of a locking dog 18 pivoted at 19 to a portion of the bracket 14. When the machine is stopped the dial is returned to starting position by a coiled spring 20 which is fastened at one end to the head of the stud 12 and at its other end to a pin or stud 21 on the dial, asshown in Fig. 10. Adjustably mounted in the dial are a plurality of controlling pins 22 adapted to be moved into operative position, as shown in Fig. 7 or as indicated by the groups of pins 00, y and a, in Fig. 4, and when in such position said pins engage and elevate the end 24 of lever 26. pivoted on the stationary stud 28 carried by the bracket 14 and having fastened to its lower end alink 29 that is connected to the controlling lever 30. The hub of the controlling lever 30 is mounted on a bearing 31 supported by the extended end of the stud 12, as shown in Fig. 10, and said lever is provided at its lower end with a shoe 32 which engages rollers 39 carried by the pawls a and holds them out of contact with the ratchet wheel a of feed roll a? whenever said controlling lever is moved inwardly as the end 24 of lever 26 is elevated. The controlling pins 22 are moved outwardly into operative position by means of a plunger 33 mounted in a sleeve 34 fastened to the bracket 14 and surrounded by a coiled spring 37, as shown in Fig. 7, the operator moving the dial to bring the desired pin into alinement with said plunger. For restoring the pins to inoperative position a device 35 formed of sprlng metal is rotatably mounted on the stud 12 and is provided w. in any desired sequence as the controlling pins on'the dial'govern'the operation of the controlling lever 30 which governs the feeding of the strand, and accordingly comprises the means for governing the insertion of the fastenings. Fig. 4 shows the controlling pins on the dial arranged to produce the design Q of Fig. 11, the pins being arranged in alternate groups of three pins in operative position and three pins in inoperative position, so that the end 24 of lever 26 will be held elevated for three consecutive operations to cause the pawls which actuate the feed roll a to remain inoperative for that period, then permitted to assume its normal position for three consecutive operations, so that said pawls can actuate the roll a to feed the strand of wire to for that period, etc. hen alternate pins on the dial are moved into operative position, the design R of Fig. 11 will be produced, and if all the controlling pins are moved into operative position the roll a will not act on strand w, and no fastenings will be formed thereby.

For preventing too free movement of the controlling pins and insuring that they will remain in either operative or inoperative position, U-shaped springs 80 are mounted in the dial and engage notches formed in the pins, as shown in Fig. 8.

In order that the same design may be produced repeatedly on different pieces of stock, the dial is arranged to be returned by the spring 20 to starting position whenever the machine stops, this being effected by the following mechanism. A rockshaft 40 which ismounted in the head of the machine has at its rear end an arm 41 that is connected by a link 42 to a pin 43 on the horn-depressing lever e said link having a slot 44 which receives the pin 43 so that the normal movements of the lever e for depressing the horn to permit the stock to be fed will not impart movement to link 42. When the machine stops, however, the extra movement which is imparted to lever 6 as previously described, will cause the link to be actuated and thereby rock the shaft 40. At the front end of said shaft is an arm 46 connected by a link 47 to a pin 48 on the locking dog 18, said shaft being provided with a second arm 49 which contacts with thepawl 16, as shown in Fig. 4. The locking dog 18 is provided with a pin 501 which passes under the lever 26, so that when the shaft 40 is rocked as the machine comes to rest the link 47 will elevate the locking dog and also move the end 24 of lever 26 out of position, to be engaged by the controlling pins on the dial, and the arm 49 will move the pawl 16 out of engagement with the ratchet teeth on the dial, thereby releasing the dial and permitting the spring 20 to return it to starting position. When the machine is again started the rockshaft is rocked back to normal position by means of a spring 69 (Fig. 3) fastened at one end to the arm 41 and at its Cix other end to a stationary bracket 66, and the pawl 16 and locking dog 18 are again moved into engagement with the teeth on the dial by means of a leaf spring 191 carried by the pawl and a coiled spring 81 fastened at one end to the pin 48 and at its other end to the bracket 14. The link 47 which moves the locking dog 18 is provided at its upper end with a head 83 having a slot that receives the pin 48 011 the locking dog, as shown in Fig. 9, so that when the rockshaft occupies its normal position and the link 47 is depressed, said locking dog can oscillate slightly on its pivot as its lower end is engaged by the teeth on the.

dial. The startingposition of the dial is governed by a stop lever 50 mounted on the bearing 31 and within the hub of the controlling lever 30 and provided with a i stop 51 that cooperates with a stop 52 on the back of the dial. A spring abutment 53 adjustably held in position in the bracket 14 by a clamp nut 55, controls the position of the stop lever which is held normally in 1 contact therewith by a coiled spring 54 fastened at one end to said lever and at its other end to the head of the machine.

From the foregoing description it will be seen that when the machine is at rest the pawl 16 and locking dog 18 are disengaged from the ratchet teeth on the dial so that said dial can be manually rotated to bring any one of the controlling pins on the dial into alinement with the plunger 33 that moves said pins into operative position, the stud 21, which is extended from the front of the dial, being adapted to be grasped by the operator for this purpose. The dial may be temporarily locked in any position i to which it has been moved, by means of a manually-operated spring-pressed plunger mounted in a sleeve 61 fastened to the bracket 14 and having a tapered end which engages the teeth on the dial when said plunger is depressed.

A rim 84, which surrounds the dial and which forms part of the bracket 14, is provided with a projection 85 that is in alinement with the plunger 33, thereby enabling the operator to tell just how far he must move the dial to place in alinement with the plunger 33 the controlling pin which it is desired to move into operative position. Said rim has openings through which the pawl 16, dog 18, lever 26, and plunger 60 project, and is also provided with a second projection 86 which is directly above the first effective pin on the dial when said dial is in its starting position.

As the number of fastenings which would be inserted in the sole or heel of a shoe of any size is less than the number of controlling pins on the dial, said dial never makes a complete revolution when shoes are being operated on, before the machine is stopped to place upon the horn the next shoe in which the fastenings are to be inserted. If, however, a piece of stock larger in dimensions than the periphery of a shoe sole should be operated on, and it should be desired to insert more fastenings than the number of controlling pins on the dial, the continued operation of the machine would cause the dial to make more than one complete revolution, thereby causing the stop 52 on said dial to engage and displace the stop lever 50, probably resulting in damage or breakage of some part of the machine. To prevent this from occurring, the dial is provided in its periphery with a notch 87, and when the dial is in its starting position said notch occupies the position relatively to the pawl 16, shown in Fig. 4. One complete revolution of the dial carries the notch into position to be engaged by the pawl 16, and as there are no teeth in said notched portion, the pawl cannot impart further movement to the dial, the operator then stops the machine, and the spring 20 returns the dial to starting position.

Manually-operated means is also vided for actuating the rockshaft 40 to cause the pawl 16 and locking dog 18 to be disengaged from the dial and permit the dial to remain inoperative while the other elements of the machine continue in operation. This enables the feed roll a either to feed the strand of wire w at each operation of the machine or not feed said strand at all, without necessitating the adjustment of all the pins on the dial in either operative or inoperative position, for if the dial remains inoperative and the controlling pin which is in alinement with the end of the lever 26 is moved into operative position the free end of said lever will be held elevated and the feed roll a will remain inoperative and no fastening from coil W will be inserted, but if said pin occupies its inoperative position the lever 26 will assume its normal position and the roll a will feed wire from coil W at each operation of the machine. The means for manually rocking the shaft 40 and holding it in this position comprises a dog 65 pivoted at 67 to a bracket 66 on the head of the machine and adapted to be moved into the dotted line position shown in Fig. 3 to cause its end 68 to engage the arm 41 fastened to said shaft and rock it.

The end 68 of dog 65 is so formed that wh en moved downwardly from the full-line position of Fig. 3 it will rock shaft 40 sufiiciently to disengage the pawl 16 and lock ing dog 18 from ratchet teeth 11, but not sufficiently to bring pin 501 into engagement with lever 26, and thus carry its end 24 to a position where it cannot engage pins 22. Preferably dog 65 is so constructed that, if desired, shaft 40 can be rocked still farther than to the position above indicated, so that pin 501 may engage and move lever 26 and the parts will all occupy the same positions 7 as they do when the horn is released and the machine is at rest. This may be done, as shown, by providing the end 68 of dog with two steps each of which, when brought into contact with arm 41, will give a different angular movement to shaft 10.

One design which it has been the practice 1 duce this design, by means of this machine,

on the. heel of a right shoe requiring fortyfour slugs to form a complete line around its periphery, the. first twenty-two controlling pins on the dial are moved into opera-tiveposition, the next twelve are left inoperative, and the next ten pins on the vdial are moved into operative position,.so

that when the machine is started the free end of the lever 26 will be held elevated during twenty-two operations of the machine to cause the feed roll 01F to remain inopera tive, said lever then assuming its normal position for the next twelve operations of the machine to permit the roll a to feed the wire to at each cycle of operations to form fastenings, and then being again elevated while the remaining ten fastenings of the outside row are being inserted. hen inserting fasten-ings in the heel of a right shoe, the first fastening is inserted at the inside corner 2'0 of the breast of the heel, the shoe being fed and turned in the direction of the arrow in Fig. 12 to cause the fastenings to be inserted in a line conforming to the contour of the heel, the last fastening being inserted at the outside corner 00 of the breast. As both right and left shoes are placed on the horn in the same position, namely, with the toe portion of the shoe extending to the left of the operator-as he faces the machine, as shown in Fig. 1, it is apparent that the first fastening which is inserted in the heel of a left shoe will be inserted at the outside corner 00 of the breast of the heel and the last fastening at the inside corner to of the breast. Consequently, when the heels of a pair of shoes are provided with inside rows of fastenings extending for only a portion of the d-istance of the outside rows it is necessary that the first fastening of the inside row be inserted at a different point in the cycle of operations of the machine when the left shoe is being operated on, in order that the inside row of each shoe will occupy a corresponding position in the tread face of the @heel. "To obtainthis result without having .of link 17 releases the link '72.

to change the position of the controlling pins on the dial when right and left shoes are being operated 011, means are provided for changing the starting position of the dial when fastenings are being inserted in the heel of a left shoe, said means comprising a handoperated lever pivoted on the shaft 7L2 and connected by means of a link 72 with the stop lever 50, so that by moving the free end of the hand-operated lever 7 0 inwardly the stop lever will be moved in the direction of the arrow in Fig. 9 and cause the stop 51 carried thereby to engage the stop 52 on the dial and rotate it forwardly a distance equal to that which it would be moved by the pawl 16 during twelve operations of the machine. The lever 70 is connected to the link 72 by a pin 911 on the lever engaging a cam slot 901 in the end of the link, and said link is also provided wit-h a lug 931 which rides up the inclined end of the head 83 of link 47 whenever the free end of said lever is moved inwardly, the action of the pin 911 in the slot 901 drawing the link 72 downwardly, so that the lug will catch behind the head 83, as shown in dotted lines in Fig. 9, and thereby hold the stop lever 50 and the dial in their adjusted position.

When the machine is started the link -17 will be depressed, as previously described, and as the head on said link moves out of engagement with the lug on link 72 the means of the locking dog 18 which engages the teeth on the dial before the depression When the dial is in this position and the machine is started, the end 24 of lever 26 will be held elevated for only ten operations of the ma chine, then allowed to assume its normal position for the next twelve operations, and thereafter held elevated while the remaining twenty-two fastenings of the outside row are being inserted. It will be understood that by changing the position of the spring abutment 53, the starting position of the dial will be varied, and accordingly the distance which it is moved by the hand lever 70, so that the location of the inside row of fastenings may be varied :as well as the number of fastenings which are inserted in said row.

The operation of the machine is as follows: After the operator has adjusted the controlling pins on the dial in the order rcqzui-red -.to produce the desired design he places the stock on the horn and elevates the rod C to start the machine. As the main shaft revolves the arm h is actuated to force the awl into the stock, and the frame which carries the awl bar is moved laterally to cause the awl to feed the stock, the awl being thereafter withdrawn from the stock and moved back to starting position. The

movement of the arm it for forcing the and into the stock operates pawl 16 to move the dial one step forward and if the first controlling pin on the dial occupies its operative position it will engage the end 24. of lever 26 and rock said lever to move the controlling lever 30 inwardly and cause its shoe 32 to engage the rolls on the pawls a and hold them out of contact with the ratchet wneel a of feed roll a At this point in the machines cycle of operations the pawl carrier a is actuated and the pawls a carried thereby engage and rotate the ratchet wheel a of feed roll a for feeding the strand of wire w into the wire-receiving opening in the throat mounted on the end of shaft 7.2 The sleeve lu which surrounds said shaft is then oscillated to cause the cutters m and m to sever the wire to form a fastening, and after the fastening has been formed the shaft 76 is reciprocated longitudinally of the sleeve to place the fas tening in the throat in alinement with the driver Z9 which is then depressed to force the fastening out of the throat and into the stock clamped between the foot plate and the tip of the horn, the machine then having completed one cycle of operations. The dial is moved one step forward at each succeeding cycle of operations, and the feed roll a is either actuated to feed the strand of wire to forward to form a fastening, or said feed roll remains inoperative, depending upon the position of the controlling pins on the dial, the pins that are in operative position actuating the lever 26 for causing the feed roll (W to remain inoperative, and those that are in inoperative position permitting said lever. to assume its normal position to cause said feed roll to become operative for feeding said strand of wire. When the machine is stopped, the extra movement, which is imparted to lever by the tappet cam f and pawl f, moves the link 42 to rock shaft 40 and thereby carries the pawl 16 and lccking dog 18 out of engagement with the teeth on the dial and also moves the end of lever 26 out of position to be engaged by the controlling pins on the dial, said dial being then rotated by spring 20 back to its starting position, which is determined by the stop lever 50. When the machine is again started the spring 69 rocks shaft 10 back to normal position, and the pawl 16 and locking dog 18 are moved, respectively, by the springs 191 and 81 into engagement with the teeth of the dial, the free end 24: of lever 26 also moving into position to be engaged by the controlling pins on the dial. When it is desired to change the design in which the fastenings are to be inserted, the arrangement of the pins on the dial is changed by means of the plunger 33 and the device 35, the dial being manually rotated to bring the pins which itis desired to move into operative position into alinement with said plunger. If fastenings are to be inserted in the tread face of the heel of a right shoe in the design shown in Fig. 11 the pins on the dial are arranged as previously described, and the stop lever 50 is retained in its normal posit-ion, shown in 9, but when a left shoe is to be operated on, the hand-operated lever 70 is moved inwardly to carry the stop lever 50 in the direction of the arrow in said figure for changing the starting position of the dial.

While the preferred form of the invention is herein shown as embodied in a machine having means for feeding two strands of wire and means for governing automatically the feeding of only one strand, it will be understood that the feeding of the other strand could be governed in the same manner were it not for the fact that it is desirable to insert at each operation of the machine a fastening formed from this strand to fill the openings made in the stock by the awl, which in the machine herein shown comprises the means for feeding the stock. As previously pointed out, however, any other kind of stock-feeding mechanism may be employed without departing from the scope of the invention. Furthermore, it will be understood that the invention is not limited to a machine in which fastenings are formed from continuous material and driven into stock, but in. its broadest aspect covers a machine for driving previously-formed fastenings, such, for example, as out nails, and having means for overning automatically the operation of t 1e mechanism that presents the nails to the driver, whereby a nail can be inserted at each successive operation of the inserting mechanism or'at intermittent operations. A machine of this type could also have provision for handling a plurality of diflerent kinds of nails for insertion either in the same row or in different rows, and in such a construction the means for governing the mechanism that presents nails of one kind to the inserting mechanism will be independent of the means for governing the mechanism that presents nails of a different kind to the inserting mechanism.
