UNITED STATES MICHAEL W. KELLY, OF ROCHESTER, NEYV YORK.

SHO EHORN-PULLIING MACHINE.

Application filed May 2,

T 0 all whom it may concern.

Be it known that I, MICHAEL W. KELLY, a citizenof the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Shoehorn- Pulling Machines of which the following is a specification.

The object of this invention is to provlde a new and improved machine for pulling out a. shoe horn from between the last and the upper of the shoe that has been inserted during the manufacture of the shoe.

This and other objects of thisv invention will be fully illustrated in the drawing, described in the specification and pointed out in the claims at the end thereof.

In the accompanying drawing:

Figure 1 is a perspective view of the shoe horn pulling machine mounted on a work bench.

Figure 2 is a detail perspective view of a shoe horn.

Figure 3 is a detail perspective view of the pulling latch of the machine.

Figure 4 is' a detail perspective view of the last supporting pin mounted on top of the shoe horn pulling machine.

Figure 5 is a detail perspective view of the socket in which the last supporting pin is mounted.

Figure 6 is a detail view of the upper end of the standard of the shoe horn pulling machine.

In the several figures of the drawing like reference numerals indicate like parts.

During the manufacture of shoes according to a well known process a shoe horn has to be inserted between the upper and the last of the shoe in order to get the last into place in the shoe. After this operation is completed the shoe horn must be pulled out from between the last and the upper of the shoe and it is this operation that the machine forming the subject matter of my present invention is adapted to perform.

As illustrated in the drawing the machine comprises a hollow standard made up of a pipe 1 having the floor plate 2 threaded to the lower end thereof. The floor plate is suitably fastened to the top of the work bench 3 so as to be rigidly supported thereon. To the upper end of the pipe 1 is threaded the socket at. In this socket is supported the arbor 5 having the last supporting pin 6 moun ed centrally thereof. The ar or 5 is 1924. Serial No. 710,675.

slightly tapered and rests within the sleeve or socket 4 to support the last supporting pin centrally of the standard.

Vithin the pipe 1 of the standard is mounted to slide the rod 7 having the pulling latch 8 fastened to the upper end thereof. For this purpose the upper end of the rod 7 is slotted to receive the inner end of the latch 8. Pins or rivets pass through the slotted end of the rod 7 and inner end of the latch 8 to securely anchor the latch in place on the end of the rod. The latch 8 projects through the slot 9 cut into the pipe at the upper end thereof and is adapted to slide up or down therein. The rod 7 projects through the floor plate and passes through the work bench on which the standard is mounted. At its lower end the rod has a suitable yoke 10 attached thereto to which the connecting link 11 may be attached. A second connecting link 12 is adjustably clamped to the connecting link 11 to connect the lower end of the rod 7 to the foot treadle 13. This treadle is mounted on the floor underneath the work bench so that it can be conveniently operated by the foot of the operator who manipulates the shoe horn pulling machine.

Stretched between the lower end of the rod 7 and the under side of the work bench is the spring let. This spring normally keeps the rod 7 and with it the pulling latch 8 in its uppermost position ready to engage into the side of the handle of the shoe horn 15. This shoe horn is illustrated in detail in Figure 2 and comprises a vertical sheet metal channel having its lower end cut back to form a handle for the shoe horn. At the extreme lower end the sides of the handle are extended and overlap each other so that they can be riveted together as illustrated at 16 in Figures 1 and 2.

The shoe horn 15 is placed between the upper of the shoe and the last on which the upper is supported when the last is put into the shoe. In order to pull out the shoe horn after the last is in place in the shoe the last with the shoe is centered on the last supporting pin as illustrated in Figure 1. In this position the pulling latch 8 projects into the channel shaped handle of the shoe horn 15 at a point above the closed end thereof.

The operator then places his foot on the treadle 13 and depresses it. On the depression of the treadle the rod 7 and with it the pulling latch 8 is pulled down. As soon as the pulling latch on its descent engages the I 1,570,679 PATENT OFFICE.

closed end of the handle of the shoe horn it pulls the shoe horn down and out of the shoe with very little ellort leaving the last and shoe in place on top of the standard.

After the shoe horn is pulled out the operator releases the treadle and the spring 14; pulls the rod back to its normal position ready to pull out the shoe horn from another shoe. lVhile a pair of links 11 and 12 are shown as forming the connection between the lower end of the rod 7 and the treadle 13 it is readily seen that any other connection formed by a cable, chain etc. may serve the purpose equally well.

I claim:

1. In a shoe horn pulling machine the ton'ibination of a hollow standard, a socket mounted on top of said standard, an arbor supported within said socket and projecting upwardly tl'ierer'rom, a rod mounted to reciprocate within said standard, a pulling latch carried in the upper end of said rod,

said pulling latch projecting to one side of said rod and thru a slot in said standard, a treadle, adjustable means connecting said treadle with the lower end of said rod to reciprocate said rod within said standard and move said pulling latch up or down on the outside of said standard.

2. In a shoe horn pulling machine, the combination of a vertical pipe, a floor plate threaded into the lower end of said pipe, a socket threaded into the upper end of said pipe a last supporting pin supported within said socket and projecting upwardly therefrom, a rod mounted to reciprocate within said vertical pipe, a pulling latch carried on the upper end of said rod and projecting thru a slot in said vertical pipe, a treadle, adjustable means for connecting said treadle with the lower end of said rod.

In testimony whereof I affix my signature.

MICHAEL lV. KELLY.
