Patented Feb. 6, 1940 I FASTENING INSERTING MACHINE Fred N. La Chapelle, Beverly, Mass, assignor to" United Shoe Machinery Corporation, Borough of Flcin'ington, N. J., a corporation of New Jersey Application September 10,1938, Serial No. 229,233

14 Claims.

I 'lhis invention relates to-fastening inserting machines and is illustrated herein by way of 1 example as "embodied in a machine arranged to insert fiber fastenings in shoes.

' An object of the invention is to provide in a machine of the type referred to improved means for adapting the. machine for 'use in inserting fastenings across the forward portion of a heel on a shoe adjacent to the breast of the heel.

To the attainment of this object the invention provides, in accordance with one feature, improved means forsupporting ,a .shoe while it is moved transversely of theffastening inserting instrumentalities of the machine to permit said instrumentalities to insert fastenings' across the forward portion of a heel on-the shoe adjacent to the breast of the heel, said means, as herein illustrated, comprising a plate "of" substantial width mounted 'onawork support 'or spindle which is normally'arranged to swing relatively to the fastening inserting instrumentalities'about axes located forwardly of said instrumentalities to permit the'shoe to be turned whilefastenin'gs are inserted around the sides and back of the heel. I The shoe is moved across the plate while fastenings are inserted along the breast of the heel-and is supported by the plate during the inserting operation.

In accordance with another feature of "the" invention, improved means is provided for guiding the shoe during both the insertion offa'stenings around the sidesand back of the heel and across its breast, this means, as herein illustrated, comprising a pair of gages arranged tobe moved separately into and out of operative position, the

heel breast gage being arranged to'engage the.

breast of the heel forwardly of'the' drivingcinstrumentalities but rearwardly of the axes about which. the work support. swings.

vAny tendency by reason of this arrangement for the work support to swing inwardly' duringthe insertion of fastenings across the breast of the heel and move the shoexaway from the heel being in alinement when the work support is. in. a proper position for supporting the shoe while the heel breast fastenings arebeing inserted.

-With the above and other objects and features in view, the invention will now be described with'reference to the accompanying drawings,

and will thereafter be pointed out in the claims. In the drawings, Fig. '1' is a side elevation 'of a machine emibodying the present invention with parts broken away andin section; v

granted-June 8, 1926, on an application filed in thename of Fred L. MacKenzie' but with the pawl and ratchet mechanism of the horn release I modified as shownin United States Letters Patent No. 1,686,808, granted October 9, 1928, onan application filed in the names of George Goddu and Fred L. MacKenzie',fthe machine being further modified to adapt it for inserting fiber fastenings instead of :loose nails, as disclosed in Letters Patent of the United'States No. 1,849,253, granted March 15,1932, on an application filed in the name of Fred N. La Chapelle. Reference may be had to the patents mentioned for such parts of the machine as it is'unnecessary to illustrate herein. I

The machine is provided with a column I0 whichsupports at itsvupperv end a head I2 pro-' vided' with fastening inserting instrumentalities indicated generally in Fig. 1 by the numeral 14 and including an awl l6 ,'and a driver (not shown) arranged to punch a hole in the work being operated'upon, to feed the workinto alinement with the driver, and to drive a fastening.

into the hole. The fastening is composed of fibrousmaterial, such as paper, twisted and treated to form a stiff peg, this material being carriedby a reel 18. The awl and driver are cam operated, as disclosed in the Goddu et al. Patent No. 1,686,808 above referred to, and the fastenings are cut and delivered to a nozzle or throat movable into line with the driver in the manner disclosed in the La Chapelle Patent No. 1,849,253. The head of the machine is also provided with ill wardly and has attached 'to its lower end a casing 28. The casing carries a slide 38 upon which'ismounted for rocking movement transversely of the machine a member 32 and uponwhich is to the machine head aboutthe pivot 34.

The work support or jack, including the spindle 36, is arranged to be moved'upwardly by a treadle 38 to bring the work, such as a shoe A. into engagement with the abutment 26 to measure the thickness of the work, the work support being then locked in this upper position by mechanism contained in the casing 28 and fully disclosed in the MacKenzie Patent No. 1,587,848. Continued depression of the treadle38 causes it to become disconnected from the measuring and locking mechanism and to operate further'mechanism, contained within the column If! and indicated generally in Fig. 1 by the reference numeral 46, to raise the post 22 and press the shoe against the abutment 20 under the force of a spring 42, thereby clamping'the work during the operation of. the fastening inserting instrumentalities. The mechanism 46 then operates automatically to release the shoe from the abutment 20 to permit the awl to feed the same after which the -mechanism clamps the work again before another fastening is driven. This mechanism for causing the work support to clamp and release the work during the fastening inserting operation is'fully disclosed in theGoddu et a1. Patent No. 1,686,808 referredto above; r

The present machine is adapted to insert fase tenings formed from fibrous material around the sides and back of a heel on a shoe and alsoto insert fastenings across the forward portion of the heel adjacent to its breast to complete the attachrnent of the heel to the shoe, this i'operation being sometimes referred to as slugging the heel on the shoe. It will be obvious that when the machine is inserting fa'stenlngs around the sides and back of a heel B, which may be composed of either leather or rubber, the work support 36 must be freeto' swing relatively to the fastening insertinginstrumentalities to permit the shoe to be turned into positions in which the 'fastenings can be inserted around the periphery of the heel, as shown in Fig. 4. Free swinging movement of the work-support 36 transversely of the machine is permitted by the member 32 and swinging movement inwardly and outwardly of the machineis permitted by the pivot 34. Accordingly, when slugging around the sides and back of the heel, theoperator is able to swing the work support both lengthwise and transversely of the fastening inserting instrumentalities and thus control the positions of the fastenings inserted around'such portions.

f When performing this'operation the work support is provided atits upperendwith the usual vided with ears 48-b'etween'which is mounted on' an eccentric pin 56 a holding member 52 provided at its lower end with ratchet teeth 56 arranged to:

engage with teeth on a member 56 fixed to the support 36 whereby the holding member 52 may be adjusted to vary its. angle relatively to the spindle 36.

Since this mechanism is well known in the art, a further'description of it need not be given herein.- When fastenings are being inserted around the sides and back of the heelB,

therefore, the, shoe A, which is mounted on .a last (){is supported by the engagement of the last pin -44 in: the hole; or-thimble in the heel end ofthe last, as shown in Figs.4 and 5.

pivoted on a horizontal pin 34 a spindle 36which- In order that the fiber fastenings,wh1ch arein can swing inwardly and outwardly with 'respect dicated by'the numeral 56, will be located a proper distance from the periphery of theheel B, the machine is'provided with a gage 6!] ariran'ged'to engage the edge face of the heel around its sidesand back and maintain the heel infthe ing instrumentalities during the fastening inserting or slugging operation. The gage 66 is adjustablymountedpnan arm 62 whereby the gage may be adjusted lengthwise for shoes of different sizes and itis held in adjusted position by a screw 66. Thearm 362 has a hub portion 65 rotatably mounted on a shaft 66 (Fig. 2) supported in'ahorizontal bracket fidyhaving a plate-like portion 69 secured by, screws'm to the under side of the machine head some distance rearwardly of the fastening. insertingmechanism M. The hub -65 of thearm 62 has alpin .12 secured in an opening therein. and'projecting inwardly beyond the hub,

the pin having arounded end adapted to enter shown in Figs. 4 and 5. The hub '65 isurged yieldingly against the bracket 68by a spring [8 surrounding :a spacing bushing or collar'86 slidably mounted on the shaft 66, the spring and bushing being' retained onthe shaft 66 by a nut. 82

, threaded on the end of the shaft. The bushing depression 'Mwagains't the force of the spring and" to'be swungdownwardly into the position shown in'Fig'; 3',.in.which position the pin 12 snaps into the other depression 16 and maintains the arm and gage 60 in an inoperative position away from the shoe. :It will be seen from the foregoing that when the gage 66 is engaging the edge face of the heel B for; guiding'the shoe while fastenings are being inserted around the sides and back of the heel, the downward force or pressure of the driv-' ing-instrumentalit-ies l4 tends to swing the work} I support 36 inwardly about the pivot 34 to hold the shoe infirm engagement with the gage 60 when a fastening is driven. In other words, since the pivot 34 15 located'forwardly of the line of drive,

the driving action'tends to swing the jack inward;-

1y about the pivot 34 and thus press the heel.

firmly against the'gage 60 which is located in wardly of :the driving instrumentalities 14.

When-it is desired to insert fastenings across the. front portion of the heel 3 adjacent and to the fastening inserting instrumentalities and,v

since the'fa'stenings are positioned and inserted with reference'to the breast of the heel, the shoe must'be guided from said heel breast. The means proper position relatively to the fastening insertfor supporting the shoe and permitting movement thereof; transversely of the fastening inserting instrumentalities comprises a relatively wide plate 8.6 (Figs. l-to 3, inclusive) [which may be removably secured to the holding member 52 of the work support 36. in the same manner as the last pin 44 was secured thereto by a pin 88'entering a hole in the'member 52 and being retained in the hole by the spring as engaging a projection 90 extending laterally from the pin 88. The plate 86, as shown in'Fig. 2, is of suflioient width to permit the heel portion of the last C to rest thereon and be moved.

' machine to locate the shoe in proper positions for across the surface of the plate transversely of the et fia opposite the end at which the arm 62 is located. The hub 96 carries a pin 98 having a rounded end adapted to enter each of two depressions'l'or holes 100, I02 formed in the surface of the'bracket '68 abutting the hub, this arrangement causing the arm 94 and gage 92 to be located .in operative position when the pin is engaging the hole I00 (Figs; 2 m 3) and to be located in an inoperative position away from the shoe when the pin is engaging the depression I 02,

as shown in Figs. 4 and-5. The spring I8 per-.

-mits movement of the hub 96 lengthwise of the shaftx66 to cause the pin 66 to be cammed out ofv one holeby rotation of the hub and to snap into the other hole as the arm and gage'are moved from operative to inoperative position or vice versa.

.It. will be seen from Figs. 2 and 3 that the gage 92 projeotsforwardly of the fastening inserting instrumentalities in order to engage the breast of the heel. Accordingly, the pressure of the fasteninginserting operation. against the plate 36 and work support 36 will tend to swing the work support inwardly about the pivot 34 and thus move the heel away from the breast gage 92' if the work supp'ortwere free to swing about that pivot during the fastening inserting operation. In order to prevent swinging movement of the work support and to insure that the shoe can always be held firmly by the operator against the gage 92 when slugging across the breast of the heel, the machine is provided with means for locking the work support against swinging movement during the insertion of fastenings across the heel breast. At its lower portion thework support is provided with a projection I08 through which is bored a relatively largehole IIO which is substantially parallel to the adjacent upstanding portion of the work support; Bolted to the slide 30 by a pair-of bolts H2 is a bracket II4 having a hole II6 formed therein the same size as thehole H0" in the work support and located at such an angle that the hole III] will be'in alinement with the hole H6 when the work'support is in a pro-per angular position for supporting the shoe while slugging across the breast of the heel. In other words, when the plate 86 is -in'a position to support the last C directly under the fastening inserting instrumentalities so thatthe shoe may be supported under the line of drive,- the holes Ilii and IE6 are in alinement with each other. The casting H4 is further secured to the slide 60b}! 'a clampin p te 8 arranged to engage the inner-side of the slide and provided with forwardly extendingbolts I20, I22 which pass through the hole II6 andhave nuts I24, I26 threaded on' their outerends.

Securedby a chain I28 or other suitable means to a lower portion. of the machine frameis a locking pin-l30 which is arranged tofit slidingly into the holes I I0 and I I6 when they are in aline- .ment and thereby lock the work support 36 rigidly against swinging movement'while fasteningsare being inserted across the breast of the heel. The

' locking pin I 30 is provided at its lower end with a slot I32 '(Fig. 3), which permits the pin tobe inserted in the hole I I6 without'interference with the clamping bolts I20, I22 which pass therethrough, the ,bolt I22 engaging the upper end of ,7

the slot I32 andpreventing the pin fromdropping out of the holes: Accordingly, when inserting fastenings acrossthe breast of the heel the locking pin I30 will be inserted intothe holes H0 and I I6 and the work-.- support 36 will be locked rigidly in its operative position. I

In operating the machine it is preferable toinsert the fastenings 58 around the'sides and back of the heel with the shoeheld on the support by the last pin 44 and with the work support free to swing in two directions to permit the heel to be maintained against :the'. edge gage 60 to locate the fastenings properly with respect to the edge face of the heel. After this operation'has been performed on one shoe or, if desired, on a number of shoes, the edge gage '60 may be moved from its operative position into the idle position 6 the machine while the fastening'in'serting instrumentalities insert as many'fastenings I34 as are desired across the, forward portion of the heel adjacent to its breast. The rigid condition of. the work. support 36 enables'the operator to maintain the breast of the heel against the gage 92- without difficulty while inserting the fastenings I34, the last and shoe being moved across the plate 86 by the feeding movement of the aw]. I 6.
