METAL AND RUBBER SHOE-SOLE.

Specification of Letters Patent.

Patented June 3, 1919.

Application filed February 5, 1918. Serial No. 215,507.

useful Improvements in Metal and Rubber Shoe-Soles, of which the following is a specification. V

This invention relates to a combination rubber and metal shoe sole and has for its object the production of a simple and eiii cient means for supporting the yieldable tread portion in engagementwith a metallic shoe sole which may be attached to the sole of a shoe. 7 7

Another object of this invention is the production of a simple and eilicient means for securing or holding the several tread sections oi the shoe sole together so as to permit the same to freely move under the action of the feet after the shoe sole has been applied to a shoe.

With these and other objects in view, this invention consists of certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described and claimed.

In the drawings: r V

Figure 1 is a bottom plan view of the shoe sole, 1 Fig. 2 is a side elevation thereof, 7

Fig. 3 is a section taken on line 3-3 of Fig. 1, r

Fig. 4 is a fragmentary bottom plan view of a portion of the shoe sole showing the rubber tread blocks removed therefrom,

Fig. 6 is a section taken on line 6-6 of Fig. 3, r

Fig. 7 is a section taken on line 7-7 of Fig. 4. V V

By referring to the drawings, it will be seen that 1 designates the heel section which comprises an outer flange 2 and a plurality of longitudinally extending ribs 3. These ribs 3 are also engaged by means of the transversely extending ribs 4: for the purpose of dividing the heel 1 into a plurality of pockets 5. A rubber cushion block 6 is placed within each of the pockets 5 as shown in Fig. 1, and is adapted to constitute a yieldable tread for the heel section 1. The heel section 1 is adapted to be secured to the heel of a shoe by means of suitable screws '7, these screws 7 passing through the junction is a section taken on line 5-5 of 7 point of certain of the longitudinally and transversely extending ribs 3 and 4, in this way firmly holding the heel section 1 in engagement with the heel of a shoe.

A sole section 8 is used in conjunction with the heel section and this sole section 8 comprises an arch section 9, a toe section 10 and a pair of intermediate sections 11. The arch section 9 is provided with a securing lip' 12, uponthe inner ends thereof,

which securing lip 12 is provided with suit- 7 able securing apertures 13 formed near the inner edge thereof for the purpose of permitting suitable screws to pass therethrough and allow the arch section 12 to'be secured to the arch of a shoe. sect-ions oi the sole section of the shoe 8 comprises a plurality of longitudinally extending ribs 1% and plurality of transverselyextend ng ribs 15, these rlbs 14 and 15 being 7 arranged at substantially right angles to each other for the purpose of producing Each of the plurality of cushion receiving pockets '16.

An outer retaining rib 17 extends around the entire side edge of the sole section 8 as shown in Figs. 1 and 2 of the drawings, forthe' purpose of constituting an outer retaining flange for the sole section. A yieldable or rubber cushion 18 is provided in each of the pockets 16 and projects beyond the i outer edge of the flanges and ribs carried by the sole section about one-sixteenth of an inch. It is of course, understood that the sole may be constructed of any suitable ma terial for example, the sole may be made of aluminum or steel, and that any yieldable substance may be employed in place of the rubber cushion which has been previously specified. The respective sections of the sole section 8 are preferably held in engagementwith the sole of a shoe'by means of suitable screws 19, these screws 19 pass ing through the apertures 20 formed in the sole sections 8, the sole sections 8 having the socket or aperture 20 so formed as to permit the screw head of the screws 19 'to' fit within the countersunk portion 21 of the apertures 20. It is of course desired to have the securing means or screws extend flush with the outer edge or face of the transversely extending ribs. The intermediate sections 11 are provided with a convex-shaped end and a concave-shaped end, the concave shaped end of one section interlocked with the convex shaped end of the other section. The toe sections 10 are provided with a concave shaped inner end 22 which fits over the convex shaped end of the section of one of the intermediate sections 11 as shown in Fig. 2 and the arch 9 is provided with a convex shaped end which is adapted to fit within the concave shaped end of one of the intermediate sections 11 as shown in Fig. 2.

In this way the sole section 8 will be yieldable to accommodate itself to the bend of the foot of the wearer, in this way relieving considerable strain from the wearers foot as would be the case if the sole section 8 were formed entirely rigid. It of course is necessary to provide only slight yieldable action between the respective arch section, toe sections, and intermediate sections of the sole section 8 owing to the concavo-convex connection between the respective sections as shown clearly in Figs. 2 and 5 of the drawings, which allows a sli ht yieldable movement to take place.

ach of the yieldable blocks 18 and 6 are provided with beveled side edges 24: for the purpose of preventing the outer edges of the yieldable blocks 6 and 18 from overhanging the ribs of the heel and sole sections.

The arch sections and toe sections are held in engagement with the intermediate sections by meansv of the retaining rods 25, these retaining rods 25 being provided withsuitable notches. or other securing means 26 at the respective ends thereof for the purpose of retaining the respective sections of the sole sections 18 in proper relation. These retaining rods or wires 25 extend longitudinally through the sole section as in dicated clearly in F igs. 1, 4 and 5 and necessarily pass through the transversely extending ribs 15 of the respective sections of the toe sections. Each of the ribs 15 is provided with an aperture 27, these apertures 27 being provided with Widenedouter edges 28 as shown in Fig. 6 for permitting a slight yieldable movement or swinging movement of the sections uponthe rods or wires 25 without fearof breaking or snapping the rods 25.

From the foregoing description, it will be seen that a very simple and efiicient me tallic sole has been produced which may be attached to the sole of the shoe as well as the heel thereof and thereby the sole portions of the shoe sole may accommodate itself to position of the foot while the wearer Copies of this patent may be obtained for five cents each, by addressing the of the device is walking. Furthermore the metallic portion of the sole will constitute an efiicient reinforcing means and hold the shoe against unnecessary wear and at the same time an eflicient cushion has been pro duced in the nature of rubber or resilient blocks 6 and 18, these blocks being capable of being renewed when it is so desired or after the block has become worn.

It of course should be understood that it is not necessary or desirous to limit the present invention to any form of material although it of course is desired to have the device constructed as light as possible and so construct the sole as to prevent the same from being easily worn or accidentally broken.

What is claimed is:

1. A shoe sole comprising a plurality of sections, each section being provided with a plurality of longitudinally and transversely extending rib portions for producing a plurality of rectangular cushion receiving pockets upon the under face of the sole, some of said transversely extending rib portions having transversely extending apertures provided with outwardly flared ends, retaining rods extending through said apertures and cushions positioned in said peck ets, and said sole being provided with apertures at the junction of some of said longitudinally and transversely extending ribs for the purpose of permitting fasteners which attach the sole to the shoe to pass through the sole.

2. A shoe sole comprising a body constituting a plurality of sections, said sections provided with curved abutting edges to permit the conformation of one section tothe other as one section is swung relative to the other, said sections provided with a plurality of longitudinally and transversely extending ribs for producing cushion receiving pockets some of said transversely ex-tending'ribs provided with apen tures having outwardly flared outer ends, tying rods extending through said apertures and holding said sections firmly together, and cushions positioned within said pockets.

In testimony whereof I aflix my signature in presence of two witnesses.
