I BOOT AND SHOE TACKING MACHINE.

Specification of Letters Patent.

Patented April 10, 1906.

Application filed September 28,1903. Serial No. 174,984.

' Boot and Shoe Tacking Machines, of which the following is a specification.

This inventlon relates to a tacking-machine. The machine may be used in various connections advantageouslyfor example, in

connection with an apparatus for the manufacture of shoes as disclosed in the drawings and hereinafter more particularly described.

The machine is simple in construction and.

effective and rapid in operation. I

Other objects and advantages of the invention will be set forth in the following description, while the novelty thereof will be included in the claims succeeding said description.

Referring to the drawings, Figure 1 shows the apparatus with its essential parts in side elevation. Fig. 2 is a front elevation. Figs. 3 and 4 show the device for unwinding a given length of wire from the wirereel in side elevation. Fig. 5 shows the wire-cutting device in side elevation. Fig. 6 shows the same device in plan in the positlon it occupies when the Wire is passed under the slide 10. Fig. 7is the same plan, but with the parts in the position they occupy at the cutting operation. Figs. 8 to 12 show the device for forming the wire staple, Fig. 8 showing it at the moment when the flat length of wire is being seized by the bending-hook 4 for the purpose of bending it into a staple, Fig. 9 illustrating the device in the position it occupies after a staple has beenformed by the rising of the bendinghook 4. Fi 10 shows the slide 10 moved into position un er the driver 11. Fig. 1 1 is a crosssection on the lineA B of Fig. 10. Fig. 12 is a lfii orizontal cross-section on the line C D of A drivin -pulley 41 operates the drivingshaft 42 of the machine. The latter operates the various parts by means of cams. As a rule the parts are returned to their original positions by springs.

A wire-reel 43 is rotatably mounted at the side of the machine-frame in the well-known manner. The wire 6 for the manufacture of fasteners or staples is unwound from the said reel by the machine itself.

In order to makea staple, a certain length of wire is required, which varies according to the tacking work that is to be done. i These pieces of wire are drawn ofl automatically by the machine inthe following manner: The

wire 6 passes through an arm 14, Fig. 5, provided with a pawl 19, which is forced against it by a spring in such way as to prevent it from movin backward. To the arm 14 is pivoted a be l-crank lever 12, having a roller 15 on one arm, against which acts a cam 16, Fig. 1, mounted on and rotating with the driving-shaft 42. The wire 6 passes through a slot or hole in the lower end of the other arm of the lever 12, Figs. 4 and 5. Th1slevercarries a s ring-pawl 18, which looks the wire 6 to it and causes it to move with it during its advance. When the roller 15 is pushed outward by the projection of the cam 16, the lever 12 swings with its lower end to the left, as shown in Fig. 5. The sprin pawl 18, cooperating with the lower end 0 the lever 12 holds the wire and pulls it, partially lifting the pawl 19, whereby a certain length of wire is drawn off from the reel 43. After the proj ection of the cam 16 has assed the roller 15 a spring 44, connecting t e lever 12 and the arm 14, causes the lower arm of the lever 12 to return to the position shown in Fig. 4 next to the arm 14. During this movement the pawl 18 gives way and' slides over the alreadyadvanced wire 6, while the pawl 19 looks the latter and revents it from going back to the reel 43. d set-screw 17 serves to regulate the distance between the bell-crank lever 12 and the arm 14 in the position of rest. The smaller this distance the more wire willbe advanced by the cam 16 during the presslng outward of the roller 15. The wire thus advanced passes through a small opening 45 n the wire-cutting device p into a recess 47 in a plate 46, Fig. 9, under the slide 16. The cutting device p is pivoted-about a pin 48 on the late 46 and has an arm 1' with a cam or inclined surface 2, which arm is pressed by a spring 2 against a wedge/y on the slide 10. (See Fi s. 6 and 8.) g

On t e part 46 is mounted a cutter 5. When during the advance of the slide 10 the Wedge y pushes away the projection z, the spring a being at the same time pressed outward, the wire-guide is slightly turned 1n a horizontal direction and the projecting wire comes against the cutter 5 and is cut off. (See Figs. 7 and 8.) At the same time the bending-hook 4, Fig. 9, with its lower projection 8, entering the recess 47, has during the advance of the slide 10 (see Fig. 9) come IIO ortion of the wire 6, the position of the sli e now bein such that the wire 6 lies under the latera ywidened slot 9. The cam 16, operating the roller 15, is provided with a groove 7, Fig. 9, with which engages a projection or roller 49 on the bending-hook 4. The latter on the rotation of the cam 16 slides vertically in the frame 50 between guides 51, Fig. 13; The said camgroove 7 now causes the hook to rise. The projection 8 of the hook 4, with its cooperating surface 52, pulls and bends the cutofi wire upward-that is to say, into the lateral notches of the hole 9, Figs. 9 and 10, the slide 10 standing still. The ends of the staple, owing to the upward movement of the projection 8, are bent downward in the hole 9, Fig. 12, said staple, owing to the natural elasticity of wire, resting a ainst the sides of the hole 9 in the slide and being held there by its elasticity. In this way a staple w has been formed from the wire 6, Figs. 10 to 12, and it is then only necessar to advance the slide 10 (the bending-hoo only moves up and down) in order that the staple a: should be driven by means of the driver 11 into the worksay the upper and weltwhich had been previously arran ed in position.

Having described t e invention, what I claim is 1. In a machine of the class described, a slotted reciprocatory slide and a hook arranged for reciprocation transverse to the slide and working through the slot therein,

under the cut-oil said slot having lateral notches to receive the branches of a staple formed by the hook and the latter being arranged on one movement to form a wire extending across the slot into a staple.

2. In a machine of the class described, a slotted reciprocatory slide, a hook arranged for reciprocation transverse to the slide and working through the slot in said slide, said slot having notches at one end to receive the branches of a staple formed by the hook, and means for cutting the wire into determined lengths, said hook being arranged, on one movement, to form the wire into a staple after the cutting operation.

3. In a machme of the class described, a slotted reciprocatory slide, a hook arranged for reciprocation transverse to the slide and working through the slot therein, said slot having lateral notches to receive the branches of a staple formed by the hook, and Wire-outtin means arranged for operation \by the sli e and adapted to cut wire into a determined length, the hook being arranged on one movement to form said Wire into a staple after the cutting operation.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
