MACHINE FOR TACKlNG SHOES- Specification of Letters Patent.

Patented Feb. 19, 1907.

L'Ihis invention has relation to machines fortacking the edge of an upper to the inner IO sole of a boot or shoe after the inner sole and upper have been placed upon a last, and for the purpose of. illustration it is hereinafter described in connection with a tacking-machine of the type described inLetters Patent No. 389,275, granted to E. Woodward, September 11, 1888, although it will "be understood that the invention is not limited to the details of that machine. In the machine'set forth in that patent there are provisions by whichwhen the shoe is brought into contact with the tacking-applying nozzle mechanism is'set in motion whereby a single tack is driven through the edge of the 'upper and the inner sole, immediately upon which the machine stops automatically. The operator then moves the shoe to a fresh position and effects the driving ofanother "tack. It is necessary for the operator, however, to pull over the edge of. the upper by hand in order 0 to stretch the upper properly upon the last and to then tack tion of the shoe cause the, incers to draw the upper taut around the last and practi-- cally simultaneously therewith bring the-- 4 shoe into engagement with the 'tackingmoz- 216, so as to'efl'ect .the fastening of the upper uentl'y while the machine is automatic, in t e-se'nse thatthe edge ofthe upper is automaticallygripped by the it prior to its presentation to the tacking mechanism. It has been cus- 'pincers and the tack is automatically driven into the shoe, yet the operator can draw the leather with the proper tension about the inner sole. This is an important feature of the necessary to stretch some grades of'leather or even some parts. of the upper more than others.

On the accompanying drawings, which illustrate one embodiment of the invention, to which, however, the invention is not limited, Figure.1 represents in side elevation a tacking-machine equipped with the invention,-the pincers being separated for the reception of the edgeof the upper. Fig. 2 re resents .a portion of the machine with t e pincers gras mg the up er.

shaft 11, having thereon a pat -cam,12 and-a loose pulley. 13,- containing a clutch 14. The movement of the clutchis controlled by a lever 15 and trip mechanism, .(shown in dotted lines, Fig. 1,) by whichwhen the nozzle 10 is. forced upwardly the shaft 11 is permitted to rotate once, so as to effect thedriving of one tack. The mechanism for accomplishing this operation is not fullyv illustrated, as it forms no part of the present invention, being illustrated in the Letters Patent to Woodward hereinbefore referred to.

The pincer mechanism, which forms the essence of the invention and which is used in connection .with the tacking mechanism, will now be described.

Referring to Fig. 1,it will be seen that 'ournaled on a stud 17, projecting from the head of the machine, the: e is a lever 18, whose rear end 19 is forced upwardly by a SP1 ing 20. The other end of the lever is bent upwardly. in front of the tack-driver and is apertured,

This leverforms one jaw of the pincer, I t k a and with aserrated portion b for coaction invention, as leathervaries greatly and it is- Referiing to the drawings, 10 indicates a tack-delivering member'or nozzle, and 100 the driver,'which is actuated by a horizontal as at 21, to receive the nozzle of the tacking.

with the relatively movable pincer member. The last-mentioned member is indicated at 22, and it is pivoted to a stud 23 on the upwardly-extenoing p01 tion 24 of .the lever 18. A strong leaf-sping 25 is interposed/between the two members 22 and 24 forthe purpose of throwing the upper end of the member outwardly, and thereby causing its lower end to move toward the serrated p01 tion I) of the other member. The said member 22 is provided with a serrated end I), complemental to that at I). From this description it will be seen that the edge e of the upper of a shoe (indicated at A) may be. inserted between the two pincer members, after which the 11cmbers may be caused to clamp it between them, as shown in Fig. 2.

It will be observed that the member 22 is provided with guides 26 27 for the reception lower end of this feeler projects downwardly below the end of the pincer member 22, so that it may be engaged by a shoe. A spl'ing 29 bears against a flange on the feeler and holds it .yieldingly in the pcsition shown in Fig. 1. The upper end of the feeler is provided with a pin or trip'member. 30, which is jointed thereto and which when the feeler is depressed is drawn into the guide 27 so as to hold it in alinement with the bOdYxOf the feeler.

31 indicates a hooked latch, which lies in a slot in the top of the member 22 and the hook of which is adapted to hold said pincer'member in its open position with the jointed member 30beyond its inclined end, as shown. This hooked latch 31 is bent around the driver-bar 100 and is connected to an arm 33 on an upright shaft 34, journaled in a bearing 35, formed on the head of the machine. To the upperend of the rock-shaft 34 and in vertical alinement with the arm 33 is connected another arm 36, held against the rear (See Fig. 4.) The rear face of the cam 12 is formed with a rise or projection d for rockingiithe arm 36, and thereby rocking the shaft 34 to move the hooked latch 31, as will besubsequently explained.

In practlce the operator presents a shoe to the machine substantially as shown in Fig. 1.

' The sole of the shoe is held below the feeler 28, and the edge e of the upper is inserted beover, so as to close the pincers upon the upper, as shown in Fig. 2.

able to draw the upper around the last and lay it upon the inner sole by means of th e flat wiper-face a. on the lever 18. As this is The operator is then v being accomplished the operator is moving the shoe upward, the lever 18 yielding to permit this until the folded-over portion of the upper comes in contact with the lower end of Vward, so that its hook takes overthe upper end of the pincer member 22, as shown'in Fig. 3, and as the shaft completes its revolution the projection or rise d forces back the arm 36, so as torock the shaft 34 and draw the hooked latch 31 to the right in Fig. 1, so as to open the pincer member 22 and hold it in open position, and as the shoe is moved downward by'the operator the feeler28' is permitted to move down, so that its member 30 is carried into position under the latch, as shown in Fig. .1.

For the purpose of feeding tacks singly to the tack-driving mechanism mechanism is provided consisting of'an upright rock-shaft 40, carrying an arm 41 with a roll 42 entering a cam-groove in a cam 43 on a shaft 11.

To the lower end of said shaft is secured an inwardly-projecting arm 44. To this arm'is connected a slide 45, having-a downwardlyprojecting pin 46, entering acam-slot 47 in'a plate 48, suitablysupported by a bracket.

The end .of the slide carries afinger 49, which is adapted to. enter into the delivery-chute 50 and separate the foremost tack from the others and place it in theposition to beengaged by the end of the driver. The groove 47 is so formed that as the slide 45 moves rearward the .finger 49 is moved outward from the tack-chute and rearward into position, so that when it is. again moved forward it engages the first tack in the row and forces it into the aperture in the nozzle.

' From this description it is apparent that the operator may manipulate the upper as much as he desires by the aid of the pincer before he sets the machine in motion to feed a tack to the driver and effect the-driving of the tack. Consequently he is able to last the shoe properly during the tacking operation.

It will be understood that the shoe'is l mounted upon a jack, bywhich-the operator may with his foot move -the shoe vertically and also in a horizontal direction relatively As this mechanism, however,

to the pincers. is Well known, -it is not illustrated.
