FASTENING-INSERTING MACHINE.

Application filed June 4, 1925, Serial No. 34,876. Renewed June 21, 1928.

y This invention relates to the manufacture of shoes and is disclosed herein as embodied in a fasteningunsettmg machine having a means for locating an insole in predetermined relation to a last while a fastening is driven through the insole into the last.

The requirements of good shoemaking necessitate that each insole be secured to its last with a very considerable degree of accuracy. both longitudinally and transversely. It has been proposed, moreover, as set forth in Letters Patent of the United States No. 1.67%,060, granted June 19, 1928, on my copending application, Serial No. 8,717, filed February 12, 1925, to utilize alining holes hrough the insole and in the last to position the insole and last relatively to the operating instrumentalities of a lasting machine. This requires that the insole be secured to the last with said holes in substantially mathematically exact alinement so that a pin or pins carried by part of the lasting machine may be introduced into these alining holes.

It is. accordingly, an object of the present invention to provide a fastening-inserting machine organization having positioning surfaces arranged to co-operate with corresponding positioning surfaces formed upon an insole and a last to position the insole in a predetermined relation to the last while a fastening is inserted through the insole into the last. These positioning surfaces advantagcously may take the form of one or more pins carried by a work-engaging element of the machine and co-operat-ing with corresponding holes formed through the insole and in the last. In order to insure the proper angular relation of the insole to the last and positively to prevent relative movement of the last and the insole in all directions transversely of the insole, the illus trated machine is provided with two of these 110 tioning; pins and the insoles and lasts are 'novidcd with corresponding pairs of holes, the positioning pins being located near the nozzle of the machine so that the first fastening inserted through the toe portion of each insoie into the last will be driven just forwardly of the positioning pins.

It is the usual practice to attach an insole to a last by a plurality of fastenings driven through different parts of the insole into the order to facilitate this, a feature of the invention comprises means for withdrawing the positioning surfaces of the machine from the corresponding positioning surfaces of the insole and last so that the work may be moved relatively to the fastening, inserting instrumentalities of the machine when a sufficient number of fastenings has been inserted to prevent inadvertent displacement of the insole relatively to the last thus permittin the ready presentation of different portions 0% the insole for the insertion of additional fastenings. Thus the illustrated machine is provided with means arranged automatically to move the positioning surface carrying member away from the work immediately after the insertion of the first fastening and to latch it in inoperative position while subsequent fastenings are inserted.

After the insertion of all the fastenin necessary in one piece of work, it is desirab e that the positioning surfaces should be returned to operative position before the next work piece is presented. Accordingly, another feature of the invention comprises means, herein disclosed as manually controlled, for releasing the positioning surface carrying member after the insertion of the fastenings in a given work piece to permit the return of the positioning surfaces to operative position. As illustrated, this releasing means includes a member located adja cent to the position occupied by the forward extremity of the last at the conclusion of the insertion of fastenings so that the operator may conveniently strike the last against said member and by impact of the last trip the latch which holds the positioning surface carr ing member in inoperative position so that t e latter will move into position for engagement with the next insole and last.

In order that the different fastenings insorted into each last at different times during the manufacture of different shoes thereon may not all be driven into the same hole, which would thus become enlarged and fail to hold the fastenings, a further feature of the invention comprises the mounting of the positioning surface carrying member of the machine in such a manner that it may be moved or adjusted relatively to the fasteninginserting instrumentalities of the machine without in any way changing the position at which an insole is located relatively to a last,

With the above and other objects and features in view, the invention will now be described with reference to the accompanying drawings and pointed out in the claims.

In the drawings,

ig. 1 is a side elevation of the head of a fastening inserting machine, with certain parts shown in cross-section;

Fig. 2 is a front elevation, 011 a larger scale than Fig. 1, of the worlcpositioning member of Fig. 1 and its latching and releasing mechanism;

Figs. 3 and 1 are side elevations on a la ger scale than Fig. 1 and also partly in section, Fig. 3 showing the work-locating means in Operative position and Fig. a showing it with drawn from the work and in inoperative position.

' The present invention is illustrator. herein as embodied in a machine of the type illustrated in United States Letters l atcnt No. 1,106,393, granted August 11, 1914;, on an application tiled in the name of Fred 1i. iltlac- Kenzie, to which reference may be 1 l for a fuller description of the machine.

in brief, the machine includes a nozzle 16 through which reciprocates a driver 12 carried by a driver bar 14. Driver bar 14 reciprocated once during each cycle of operation 0 the machine, moving downwardly to cause the driver to drive a tack through the nozzle into the work and then returning to its elevate/ position where it is held when the machine comes to rest. The specific mechanism tor accomplishing this, as Well as the controlling means for the machine as a whole, are not described herein since they are well known in the art and may take various terms so far as the present invention is concerned.

Mounted for reciprocating movement in a slideway carried by the head of the machine and parallel to the driver bar let is a second reciprocable bar 16, to the lower end oi? which is adjustably secured a positioning suri ace carrying member 18. At the lower end. of member 18 and located adjacent to the nozzle 10 of the machine are provided position." f surfaces, illustrated in the term of two pins 20 arranged to engage with omrrespondii positioning surfaces illustrated as holes formed through the insole 2 1 and corr soone- L ing holes 26 formed in the last 28 to whici the insole is to be tacked, arranged positively to hold the last and the insole agains relative movement in all directions transvei sely of the insole. lVhen bar 16 is in lowermost position, as illustrated in Fig. 3, pins 20 are in position to be received in holes a2 and 26 of the insole and last, locating the insole and last, as shown in Fi 3, for the insertion of a tack toward the toe of the last. Since the holes through the insole and in the last are only big enough to provide a good woi fit for pins 20, the insole and the last must be properly positioned relatively to each ,sei

other bei'ore the first fastening is inserted. Alter the lirst fastening has been inserted it is desired to move the insole and last forwardly, that is to the left as illustrated in Fig. 1, so that additional tastenings may be inserted, for example at the ball line and toward the heel. To facilitate this, the illustrated machine is arranged so that the positioning surface carrying member 18 is automatically moved to inoperative position, as shown in Fig. t, after the lirst fastening has been driven and secured in that position by a latch 36 carried by a rock shaft 32 having a bearing in a stationary part of the head of the machine, latch 30 being urged in a counterclockwise direction, as shown in Figs. 1, 3 and l, by a spring housed in a socket 36 formed at tile lower end or the latch. A notch formed in bar 16 serves for engagement with latch 30, holding bar 16 in elevated position against the resistance of a compression spring 10 housed in bar 16 and hearing at its upper end against a surface 4-2 formed on the head of the machine. Driver bar 1 1 carries a pivoted dog (Figs. 3 and having at upper end a linger l6 normally urged toward bar 16 by a leaf spring 50 engaging the lower end of dog and tending to rock it in a clockwise direction, as viewed in Fig. 3. l sl'loulder 4:8 is termed upon bar 16, so located that when bar 16 is in its lower, or operative, position, linger 1-6 of dog id will snap under shouh er 18 (Fig. as the driver bar l l reaches its lowermost position in the first cycle or operation when the machine is tarted. Then, as driver bar let moves upwardly on its return stroke it lifts bar 16 against the compression of spring -l0, shown in Fig. 1. At its lower end dog 14 is provided with a lug 52 arranged :t'or engagement, as the driver bar is elevated, with a cam surface 5% formed upon a hard plate 56 carried by the head of the machine so as to rock dog lat in a counter-clockwise direction when driver bar 141 has moved upward a short distance. By this time, however, bar 16 will have been latched in elevated position by latch 30 which, as has been already pointed. out, is urged by spring 8 1- toward bar 16. Thus positioning pins 20 will be elevated automatically as driver bar 1 1 makes its return stroke after driving the first fastening and will be secured in elevated position. Accordingly, the insole and last may be moved longitudinally and other fastenings driven without interference by positioning pins 20, the operator, or course, grasping the insole and last so as to prevent inadvertent movement of the insole relatively to the last between the driving of the first and the second tastcnings. Bar 16, member 18 and pins 20 remain latched in elevated position while successive i ast-enings are driven into the insole and last. l Vhon sutlicient tastenings have been driven, it is desir able to return bar 16 and positioning pins 20 to operative position. Accordin ly, manually-controlled means. is provided tor releasing latch 30, and in order to facilitate this, these releasing means include a plate 60 (Figs. 1 and 2) located adjacent to the position occupied by the toe of the last when the last fastening is inserted. Plate (50 is carried by a bell crank lever 62 arranged to be rocked by impact of the work and connected by a link 64 with a lever 66 rigidly secured to rock shaft 32 so that when the operator strikes the toe of the last against plate 60, latch 30 will be rocked in a clockwise direction, as viewed in Figs. 1, 3 and i, thereby releasing bar 16 so that it may move downwardly under the influence of spring 40 to bring pins 20 into work-engaging position ready for the operation upon the next work piece.

In order to prevent the difierent fastenings driven into each last during the manufacture of different shoes thereon from all being driven in at the same point and thereby soon putting the last in such a condition that the fastenings will not hold, means is provided for adjusting or moving the positioning pins 20 relatively to the nozzle 10. As illustrated this is done by connecting member 18, which carries pins 20, to bar 16 by a universal joint or pivot. As herein shown, a ball 70 is formed upon the lower end of bar 16, the ball 70 being received in a socket formed in two parts of member 18, these two parts be ing clamped together, and to ball 70 by a bolt 7 2. Then if the position of member 18 relatively to bar 16 is changed occasionally, for example once a week or once in several weeks, the position at which the tacks will be inserted relatively to the positioning pins 20 will be varied from time to time. Or, if desired, the connection between member 18 and bar 16 may be left a little loose with the same result. The position of the insole relatively to the last will be the same under all circumstances irrespective of the distance between positioning pins 20 and the nozzle so that the accuracy of the work will be in no way affected by the changes in the position of member 18.
