HEEL-ATTACHING MACHINE.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed January 28, 1903. Serial No. 140,833.

To aZZ whom it may concern:

Be it known'that I, ERASTUS /VooDwARD, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Heel-Attaching Machines, of which the following is a specification.

My invention relates to a machine for attaching heels loaded with nails to the heelseats of boots and shoes, and where blindnailing is employed to the subsequent attachment of top lifts to the attached heels.

My improvement is shown applied to a heeling-machine in which there is a vertically-reciprocating cross head carrying a hub adapted to be oscillated about a shaft and, provided with two diametrically-arranged arms, one of which carries the naildriving mechanism to which the loaded heel is applied for attachment to the shoe and the other arm being adapted to subsequently attach or spank the top lift onto the attached heel at the proper time. I have not shown in the drawings the mechanism for reciprocating this cross-head, as it is too well known in the art to require description.

My invention consists of certain novel fea tures hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying my invention, Figure 1 shows a side elevation of the cross-head referred to, together with the jack in position thereunder for holding the shoe, and also showing the loaded heel held on the upper arm, to which it has been applied by the body. Fig. 2 is a similar view with the arms reversed and showing the heel above the jack in position to be attached to the heel-seat of the boot or shoe. Fig. 3 is a top plan view of Fig. .2 and showing the toplift-carrying device out of the vertical line of motion of the arm carrying the heel during its attachment to the hcel-seat of the boot or Fig. 4 is a side elevation showing the cross-head down with the heel attached to the shoe. Fig. 5 is a side elevation similar to Fig. 4 with the arms reversed and showing the projecting ends of the nails onto which the top lift is to be attached. Fig. 6 is a view similar to Fig. 5 with the cross-head down and the spanker-block attaching the top lift to the projecting ends of the nails.

.Fig. 7 is a view similar to Fig. 6, showing the cross-head raised with the arms and the heel finished. Fig.8 is a top plan view of the toplift-earrying device in the position shown in Fig. 1 when the heel is applied by the boy to the arm carrying the heel-attaching mechanism. Fig. 9 is a top plan detail view of the toplift-carrying device with the parts in the position shown in F 2 out of the driving-line of the arm carrying the heel. Fig. 10 shows a top lift applied to the top-lift-carrying device and ready to be moved into position under the spanker-block for attachment to the attached heel. Fig. 11 is a top plan view of the top-lift-carrying device and in the driving-line of the spanker-alm for attachment of the top lift to the attached heel. Fig. 12 is a cross-sectional view through the cross-head on the line a a, Fig. 1. Fig. 13 is a cross-sectional view through the head and hub with the two arms in full lines on line 1 1, Fig. 2. Figs. 14 and 15 are respectively side and under side plan views of the mechanism wlich operates the top-lift-carrying device, representing the parts in their positions when the top-liftcarrying device is out in position to receive a top lift. Figs. 16 and 17 represent, respectively, side and under side plan views of the mechanism which operates the top-lift-carrying device, showing the parts in their positions when the topliftcarrying device is moved inward with the top lift over the heel for attachment thereto.

Like letters of reference refer to like parts throughout the several views.

In the drawings the cross-head A is reciprocated, by means of the rods A, in the manner well known in the art.

N is the last, carrying the shoe. to which the heel and top lift are to be attached when blind-nailing is employed and to which the heel only is to be attached when flush-nailing is employed. The hub B, attached fast to the shaft B, which is set at an angle of thirty degrees, carries the diametrically-arranged arms or blocks B B and said hub and arms are adapt ed to be firmly held in position dur ing the attaching operation by the arm 0,

pivoted at C on the cross-head A and nor-.

mally caused to engage a suitable recess in each arm by means of the spring C (Shown in Figs. 1, 2, and 3.) Secured fast to the lower end of the shaft B is the arm D,to which is pivotally connected at D the lever D which at its opposite end is pivotally con- -over the attached heel nected to the arm E by the pin D extending down through the opening in the movable arm E, mounted freely on the sleeve 6 around the rod E, which extends upward from the base of the machine. The end of this arm E opposite the lever D is supported in the lugs e, secured to and extending from under the cross-head A, and in the movements of the lever D the arm E moves to and fro on the sleeve 6, supported in the lugs 6. From the under side of the arm E there extends downwardly the depending rod E which passes through the slot E in the bifurcated arm E held fast on the rod E by the set-screw E Secured to the boss E on the arm E is the plate E to which-are pivotally secured two links E E at F and F. The forward end of the link E is pivotally connected at F to the arm F of the link F to which is secured the forward end of the link E at F forming the well-known parallel motion. The spring F, secured to the link E at one end and at its opposite end to the pin F tends to hold the forward end of the arm F in a parallel closed position with respect to the forward end of the plate E and exerts a pressure on thetop lift to hold it square andclamped in a suspended position as it travels into posi.ion over the attached heel. On the forward end of the plate E are two guides G G, inwhich there is adapted to slide the forked plate G having shoulders, as shown, to limit the forward movement of said plate under tension of the spring G secured to the plate E and to the pin G.

The top lift is placed on the top-lift-carrying device by putting its breast against the parallel arm F and forcing said arm out until the top lift Y drops into the fork in the plate G which yields as the arm F returns to its normal position under the tension of the spring F until the back of the top lift strikes the edge of the forward end of the plate E which is the gaging-point of the top lift, the plate H preventing the top lift falling through during its application, as above described. The plate H is located on a-suitable standard extending up from the base of the machine and is fixed in positive relation to the arm F and the forward end of the plate E so that when the top-lift-carrying device is moved out into position to receive a top lift it comes directly over the plate H in close proximity thereto and prevents the top lift when being applied thereto from passing through.

The machine is so organized that when the top lift is arranged as described and brought its rear end comes over the rear end of the heel in a positive relation to the back nail.

Depending from the under side of the lever D is the pin f, to which is attached the spring f, with its opposite end secured to the pin f, depending from the arm E, and located beyond said pin f is the slot D which is longer than the pin D so as to allow a yielding movement between the lever D and the arm E. When the top-lift-carrying device is in its outer or receiving position, as shown in Figs. 3 and 4, the cooperating parts shown in Figs. 14 and 15 are in thepositions indicated in said figures; but when the top lift moves inward over the heel for attachment the cooperating parts shown in Figs. 16 and 17 are in the positions indicated in those figures.

\Vhen the block B moves downwardly from. the position shown in Fig. 5 to that shown in Fig. 6, the top lift is spanked onto the attached heel, and owing to the force of. the

blow of the spanker-block B on the rigid heel of the shoe located on the last the leather of the top lift spreads out, which causes the forward end of the plate F to move laterally and yield by means of the spring F and at the same time the forward end of the plate E moves laterally and yields by means of the spring f, so that the top lift is not marred by the force of the blow of the spanker-block 13*,

its spreading being thus provided for as above described.

The plate E is secured to the boss E carrying the bifurcated arm E, fast on the shaft E, and through the slot E of said bifurcated arm E passes the depending rod E fast to the under side of the arm E. By the constructions previously described the plate E yields as the rod E moves the arm E slightly toward the right from the position shown in Fig. 17 by the yielding of the spring f, and after the top lift is attached the spring f returns the arm E to the position shown in lhe loaded heels are secured on the heelblock B by means of the carrying and holding fingers J, which may be of any desired construction and form no part of this inven tion. When the boy has placed a loaded heel X on the heel-block B and the same is held there by the fingers J, the boy operates the latch C to release the heel-block and allow it to be turned and brought into the position shown in Fig. 2; During this operation the top-lift-carrying device hereinbefore described moves out of alinement under the spanker-block B in the position shown in Figs. 1 and 8 to the position shown in Figs. 2 and 9, when the boy places the top lift Y on the top-lift-carrying device in the manner shown in Fig. 10. In the meantime the operator has placed the shoe A on the jack A and operates the cross-head A to bring down the heel from the position shown in Fig. 2 to that shown in Fig. 4 for attachment to the shoe and then turning the arm B brings the heel-block B up into the position shown in Fig. 5. This movement brings the top-liftcarrying device into position over the attached heel and under the spanker-block B Fig. 6, when the operator brings the crosshead A down and spanks the top lift onto the attached heel and upon the rpward movement of the cross-head A leaves the entire heel Y secured to the shoe.

When the parts are in the position shown in Fig. 1, the top-lift-carrying device is directly under the spanker-block B and over the shoe; but when the boy throws the block B to bring it around over the shoe in the position shown in Fig. 2 the top-lift-carrying device moves from its horizontal position (shown in Fig. 8) to that shown in Fig. 9, ready to receive the top lift by the movement of the lever D arm E, rod E and arm E to the boss E, to which the top-lift-carry ing device is secured. When the operator turns the arm B to turn the heel-block up and turn the spanker-block down, the toplift-carrying device, which has received a top lift, moves from the position shown in Fig. 10 to that shown in Fig. 11 through the opera tion of the lever 1)", arm E, rod E and bifurcated arm E hereinbefore described, when the top lift is in position to be spanked onto the attached heel. The hub B with the blocks B B do not rotate continuously in one direction, but oscillate in an arc of one hundred and eighty degrees.

Having thus described the nature of my invention and set forth a construction embodying the same, what I claim as new, and desire to secure by Letters Patent of the Uni-ted'States, is
