. 1 Claim. 1

This invention relates to an apparatus for nailing heels onto shoes which have been assembled on a last. It is an object of the invention to provide a simple and easy way of assembling the heel with the rest of the shoe and nailing the same securely in place. The apparatus is adapted particularly for use with shoes having relatively broad heels which are not too high since, according to the present invention, nails are driven from the bottom of the heel up through the entire heel and the heel seat so as to clinch against the steel plate which is customarily mounted in the heel portion of a shoe last.

For a more complete understanding of the invention, reference may be had to the following description thereof and to the drawing, of which:

Figure 1 is a side elevational view of apparatus embodying the invention;

Figure 2 is a plan view of the lower portion of the apparatus shown in Figure 1;

Figure 3 is a section on the line 3-3 of Figure 2;

Figure 4 is a similar section showing the parts and a lasted shoe at the conclusion of the nailing operation.

The invention is embodied in certain novel improvements in a machine much of which is old and well known in the shoe making art. This machine includes a frame ll! which can be raised or lowered through a predetermined range by operation of a treadle (not shown) or other suitable means. The machine also includes a lower anvil l2 having vertical bores is in which slidable driving rods l6 are arranged to drive nails inserted in the upper ends of the bores. Such nails are supplied to the bores by a suitable feeding mechanism [8 well known in the art, and the rods l6 are simultaneously operable for gangnailing.

According to the present invention, the lower anvil I2 is provided with a top block 28 the upper surface of which is plane, this block having bores which are extensions of the bores M. The top surface of the block acts as a support for a heel 22 which is to be nailed to a lasted shoe 24 while the last 26 is still in the shoe. Adjacent to the rear edge of the block 2|] are gauges 3!) and 32 which help in locating the heel on the upper surface of the block 20 in the correct position for nailing. As indicated in Figure 2, the gauges 3! and 32 may conveniently be projections on a single member 3 2 which is hinged as at 36 to the frame Ill so that it can be swung down out of the Way when the magazine It moves over to supply nails to the lower anvil.

Mounted on the gauges 30 and 32 are adjustable gauges 40 and i2 which project out over the lower gauges to be engaged by the quarters of the shoe 24-. After a heel 22 has been placed on the block against the gauges and 32, a shoe 2A with its last is placed in an upright position upon the heel with the shoe quarters bearing against the gauges 40 and 42.

According to the invention, the frame i0 is provided with an upper anvil M which is directly above the lower anvil and is sufliciently spaced therefrom to permit ready insertion of a heel 22 and a shoe 24 between it and the block 20. By operation of the treadle (not shown) the anvil M is made to descend so as to press upon the top of the heel portion of the last 26 and to hold the last and shoe firmly against the heel 22. While the upper anvil is in this position, suitable mechanism (not shown) is operated to actuate the rods 16 to drive the nails in the bores l4 upward through the heel 22 and the heel seat so that the nails clinch against the steel plate which is a part of the last 26 as indicated in Figure 4. After the nailing operation, the anvil Ml is elevated to permit the removal of the shoe 2 5 with the heel 22 securely nailed thereto. Nails are then supplied to the bores l4 and the cycle of the operations is repeated.

I claim:

Apparatus for nailing spring heels and the like to shoes, comprising a fixed anvil having a horizontal top face and vertical bores for nails, naildrivingmembers in said bores, a support member behind the anvil, a bracket pivotally mounted on said support member and rockable from an operative to an inoperative position, said bracket member having heel gauging elements engageable by a shoe heel to position said heel when the bracket is in its operative position, gauging members for shoe uppers secured to said bracket above said elements and adjustable relatively thereto, and an upper anvil supported above said fixed anvil and movable downward to press on the last of a lasted shoe placed on said fixed anvil.
