RUBBER SHOE HEEL SECURING MEANS Filed June 24. 1926 swam H201 Patented Get. 15, 1929 UNETED STATES NAPOLEON B. RIDDLE, OF ST. FRANCISVILLE, LOUISIANA RUBBER-SHOE-HEEL-SECURING MEANS Application filed June 24, 1926. Serial No. 118,370.

The invention relates to means for securing rubber heels to boots and shoes.

The practice usually followed in securing rubber heels to shoes is to employ driven fastenings that are embedded in the wear face of the heel and driven upwardly into the leather heel of the shoe.

The disadvantage of this means of securing heels to shoes is that when the heel wears down the driven fastenings do not wear as rapidly as the rubber and protrude so that the protruding head scratches or otherwise mars floors, linoleum, etc. and will tear carpets, matting, etc. New rubber heels can be put on very easily when old rubber heels have been worn down.

This invention has for its object the provision of improved means for securing the rubber heel to a shoe consisting in providing the heel with an embedded plate that is perforated so that in molding the heel the rubber will pour through the perforations and hold the plate securely in position in the heel. The plate furthermore has threaded sockets thereon to receive screws or other threaded members inserted through the shoe from the inside and thus hold the heel securely in position. 7

A further object of the invention is the provision of a roughened plate secured. to the lSllOQ, the roughened surface engaging the heel when in position on the shoe to prevent movement of the heel on the shoe, the plate also serving to prevent wearing of the openings through which the screws are fastened that engage the sockets in the plate in the heel.

The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawings, in which Figure 1 is a view of a fragment of a shoe showing the heel portion with the improved rubber heel in position thereon, the view being shown partly in section,

Figure 2 is a transverse sectional view on a plane indicated by the line 2-2 of Figure 1,

Figure 3 is a top plan view of the plate,

Figure 4, an edge view, and

Figure 5 is a plan view of a modified form of plate.

' the engagement of the screw members 5 with In the drawings similar reference charac- I ters will be used to designate corresponding parts throughout the several views.

In Figures 1 and 2 a shoe is fragmentally shown and indicated at A, and has a permanently attached heel portion B. The removable heel designated 1 is made of cushion material, such for instance as soft rubber, and has embedded therein a metal plate 2 that is provided with a plurality of perforations 3 so that in molding the heel with the plate the melted rubber will flow through the openings .3 and thus make a homogeneous heel in which the plate 2 is embedded, said plate forming a reinforcement for the rubber heel, and also a 5 means for securing the rubber heel to the shoe which will be now described.

Internally threaded sockets are formed integral with the plate 2, and when the heel is finished, the sockets as shown extend to the upper surface of the heel, and are adapted to receive screws or other threaded members 5 secured through openings in the permanentv heel B, to secure the heel in position on the shoe. A metal plate 6 may also be secured to the permanent heel B, and plate 6 is provided with a plurality of pointed projections 7 that when the rubber heel 1 is in position are embedded in the upper surface of the heel to securely hold the heel from sliding movement on the under surface of the permanent heel. The plate 6 is furthermore provided with openings through which the screw members 5 are inserted, and thus serve to reinforce the permanent heel B. In the modification shown in Figure 5, a

plate 2 is provided with an enlarged opening 8, to lighten the weight of the plate, still serve to adequately reinforce the rubber heel. V This plate is also provided with perforations designated 3 and threaded sockets l.

What is claimed is 2- In combination with a shoe having depending screws at the heel-attaching portion, a heel of elastic material, a relatively thin plate embedded in said heel intermediate of the upper and lower faces thereof and reenforcing it, said plate being perforated to permit the loo flow of melted material therethrough in bolding the heel, socket members extending upwardly from the plate and opening on its upper face, said socket members being closed at the lower ends and having interior screw threads engaged by said screws.

In testimony whereof I afix my signature.
