277. 272? iEs/i ELEM/1'53 a, Patented Feb. 15, 1938 U ITED STATES PATENT OFFICE SPKKED SHOE Leslie H. LHollier, Waltham, assignor to Hood Rubber Company, Inc., Watertown, Mass a corporation of Delaware Application Decer ill, 1936, Serial No. 115,201

have usually been riveted to the rubber'sole of the shoe by clinching over the inner end of the spike. .With that type of construction pressure on the spikes parallel to the sole of the shoe has caused the spike to be tipped about the edge of the flange on the spike, exerting a poweriul leverage upon the clinched end of the spike and causing the spike to be loosened and even withdrawn from the sole. Loosening of the spikes or withdrawing of them from the sole not only results in loss of traction and discomfort to the wearer but also the openings left by the tear ing away of the spikes permit moisture to enter the shoe.

The principal objects of the present invention are to provide security of attachmentwithout excessive stiffening of the sole of the shoe; to provide comfort to the wearer and to eliminate ingress of moisture.

Other objects will appear from the-followlng specification and the accompanying drawing.

Of the drawing:

Fig. 1 is a side elevation-of a spiked shoe embodying the invention in its preferred form, parts being shown in'section.

Fig. 2 is a bottom view of the sole oi the shoe.

Fig. 3 is a vertical section showing the manner of applying the spike according to the invention.

' Referring to the drawing:

The shoe, which may be an overshoe designed to be worn over a leather shoe or a shoe to be worn directly upon the foot, comprises, for example, an upper it, of rubber, which may be provided with a lining if desired, and a rubber sole ii attached thereto. A reinforcing layer-or layers of 4 fabric or other reinforcing material i 2 maybe incorporated in the sole, preferably in its inner face, and an insole i8 is also cemented or vulcanized in place in the shoe.

Spikes M are each provided with a flange it 4 which engages the tread face of the sole and a shank l8 which extends through the sole Ii and fabric reinforcement l2 and has its inner end bifurcated to provide clinch members II.

In order to prevent tearing of the spikes from 50 the sole and also to securely seal the margins of (Cl. tid -7.6)

and the spike, and having an aperture of sufilcient size to freely admit the shank when such shank is in its unclamped condition. In inserting the spikes in the sole of the shoe use may be' made i of a rivet setting member such as that shown at 5 is in Fig. 3, and a co-operating anvil 2i), said anvil having a recess 2i in its face for receiving one of the washers i8 and also having a conical projection 22 at the center of said recess surrounded by a groove 23 which cooperates to turn and -clinch 10 the prongs of the spike. The rubber material of the sole, being resilient, aids in maintaining the clamping pressure. y

In order that the clinched ends of the spikes will be depressed below the inner surface of the 15 sole and thereby provide comfort to the wearer without objectionable contact of the wearers foot with the clinched ends of the spikes, the inner sole i3 is formed with apertures of such size as to clear the washers I8 and is made of such thick- 20 n'ess as to exceed the projection of the clinched prongs of the spike above the sole. While an auxiliary insole may be provided, if desired, this is not essential for comfort, owing to the fact that the apertures in the insole need not be so large 25 as to cause discomfort.

The metal washer securely attaches the spike to the sole of the shoe without such stiffening of the sole as would occur were a reinforcing plate of substantially the area of the sole used as a fas- 30 toning means, so that the shoe provided with the spikes is substantially as flexible as a rubber shoe not so provided.

I claim:

An article of footwear comprising a thin flexible rubber sole, apertures therethrough for receiving spikes, a plurality of metal spikes each hav ing a bifurcated shank end adapted to be deformed within the shoe for clinching, and an in tegral flange for engaging the tread side of the 40 sole, a layer or flemble non-metallic but substantially inextensible material adhered to the inside face of the sole around the apertures to prevent spreading of the material at the apertures, a washer about each shank at the inextensible layer, said washer, inextenslble layer and sole being held clamped against said use by the clinched end of the shank; and an insole at last substantially equal in thickness to the ers and the clinched ends of the shanks so as to present a substantially flush insole surface, said insole being adhered to. the sole within the shoe, and \searance openings to receive the washers.
