Application October 22, 1949, Serial No. 122,898

2 Claims. (01. 12-42) This invention relates to devices for inserting heels into the pocket formed by an insole and heel cover of ladies shoes and comprises a shoe supporting means and means for inserting heels into said pocket.

The principal object of this invention is to provide a machine for inserting heels into the pocket formed by an insole and. heel cover of ladies shoes.

Another object of this invention is to provide a mechanical means for inserting heels into said pocket of ladies shoes in a quick and positive manner.

Another object of this invention is to provide a mechanical means operated by a foot for inserting a heel into said pocket of ladies shoes so that an operator will have his hands free to help smooth the heel cover thereover.

It is the function of this device to aid in the insertion of a heel (or a heel and platform unit) into an unfinished shoe which has a top portion and a heel cover (or a heel and platform unit cover), said heel cover being a thin piece of material which covers the heel after said heel is inserted into position just beneath an insole.

Some ladies shoes contain a heel only, some a heel and platform in two pieces, and some a heel and platform in a unit. In the past, the various parts of the shoe were assembled by hand in a variety of ways some of which were as follows:

(1) With heel cover and platform cover up, (with respect to a shoe whose sole faces downwardly) a heel and platform unit was secured to the insole. The heel cover and the platform cover were then pulled down to cover the heel and platform.

(2) With the heel cover down, and the platform cover up, the heel and platform unit were driven with a mallet into the cavity formed by the insole and turned down heel cover. The platform cover was then turned down.

(3) Using a heel and a platform in separate pieces, the platform was secured in place. The heel was then inserted and the bridge so formed was driven out with a mallet.

The present invention substitutes a machine for the hand operations required in method 2 above.

In the accompanying drawings, which form part of this specification and wherein like numer als refer to like parts wherever they occur,

Fig. 1 is a side elevational view of the machine with the parts in their inoperative position,

Fig. 2 is a front elevational view of the machine with the parts in their inoperative position and with a shoe thereon,

Fig. 3 is an enlarged view of the upper portion of the machine after the pedal has been depressed, and

Fig. 4 is an enlarged cross-sectional view along the line 44 in Fig.2.

This invention is shown embodied in a table I supported on legs 2. A support 3 is mounted on said table I for holding a supporting plate 4. A platform cover turning arm 5 is pivotally mounted on a platform cover turning arm support 6 which is rigidly mounted on said supporting plate 4. .A folding roller 1 is adjustably secured to the platform cover turning arm 5 by means of a setscrew 8.

A spindle 9 and an arcuate toe positioning. plate l0 arev rigidly secured to the supporting plate 4. Heel gripping teeth H are mounted on a heel inserting arm 12 which i pivotally attached to a link US by means of a pin I4, said link l3 being pivotally attached to a link supporting lug 15 'by means of a lower pin l6 having a modified hairpin spring l1 thereover, said link supporting lug l5 being rigidly secured to the supporting plate 4. A guide roller support l8 having a guide roller I9 therein is attached beneath said supporting plate 4.

A platform cover turning arm actuating rod 20 is operatively connected to the platform cover turning arm 5 and to a pivotally attached pedal arm 2| having a pedal 22 thereon. A heel inserting arm actuating rod 23 is operatively connected to the heel inserting arm l2 and to the pedal arm 2|. One end of a spring 24 is connected to the pedal arm 21 and the other end of said spring 24 is connected to a leg 2 of the table I.

In operation, an operator positions an unfinished shoe, which is on a last 25, as shown in Fig. 2 and Fig. 3, so that a hole 26 in said last will fit over the spindle 9 of the device with the heel end of the shoe pointing leftwardly and the toe end of the shoe pointing rightwardly (as shown in Fig. 2). Cement may or may not be applied. The operator then inserts a heel 21 into the hollow space formed by the sock lining or insole 28 and the turned down heel cover 29. The operator then depresses the pedal 22 with his foot causing the heel inserting arm actuating rod 23 to move downwardly from its inoperative position until the heel gripping teeth II meet the surface of the heel 21 thereby encountering resistance after which time the heel inserting arm actuating rod 23 moves downwardly and slightly leftwardly. This drives the heel 21 downwardly and rearwardly (with respect to the shoe as shown) into the desired position. The peda1 22 is then released and returns to its raised posi- 3 tion by action of the spring 24 and the parts return to their inoperative position. The last 25 with the shoe thereon is removed from said spindle 9, with the hole 26 in the last 25 facing downwardly. The toe end of th shoe placed against the arcuate toe positioning plate ll] so that the top edge of the arcuate toe positioning plate l slips into the peripheral groove formed by the turned up platform cover 30 and the upper portion of theshoe. The pedal 22 is then depressed moving the platform cover turning arm actuating rod 20 downwardly causing the platform cover turning arm 5 to be pivoted downwardly causing the folding roller 7 attached thereto to engage the platform surface 3| driving it downwardly, thereby causing the platform cover 30 which was lapped over the convex surface of the arcuate toe position plate 10 to slide over said top edge and be turned downwardly (with respect to the shoe) Obviously, the hereinbefore described machine admits of considerable modification without departing from the invention. Therefore I do not "arm having a member thereon for contacting a heel to be inserted into said pocket, an arm actuating rod operatively connected thereto between said contacting member and said pin, a

link having one end thereof pivotally connected to said pin, said link having the other end thereof secured to a second pin, said second pin being displaced vertically from said first mentioned pin 4 and displaced laterally therefrom toward said contacting member.

2. A machine for inserting a heel into an unfinished shoe having a bottom and a heel cover forming a pocket, said machine comprising a shoe holding member, an arm pivotally mounted on a pin, said arm having gripping teeth thereon for contacting the bottom surface of a heel to be inserted into said pocket, an arm actuating rod operatively connected to said arm at a point between said gripping teeth and said pin, a link having one end thereof pivotally connected to said pin, said link having the other end thereof secured to a second pin, said second pin being positioned below said first mentioned pin and displaced laterally therefrom toward said gripping teeth, resilient means operatively secured to said link, a pedal operatively connected to said arm actuating rod for operating said machine, said resilient means being secured with respect to said link for keeping said link in its normal inoperative position until a predetermined resistance is encountered by said gripping teeth when said pedal is actuated.
