ANDREW P. ANDERSON, OF GRAND RAPIDS, MINNESOTA.

AN'IISLIP ATTACHMENT FOR FOOTWEAR.

Application filed Karch 29, 1926. Serial No. 98,294.

'.-I presentinvention relates to improve- .lilltS in anti-slipping attachments for foot- Y which will be extremely light in weight, and

one wherein, the ground engaging portions thereof are so arranged as to prevent rearward slip ing of the \vearers foot while walking.

Other objects and advantages of the invention will beapparent during the course of'the following detailed description, taken in connection with the accompanying drawing forming a part of this specification, and in which drawing,

Figure 1 is a diagrammatic top plan view of a shoe and showing the device applied thereto.

Figure 2 is a side elevation of a shoe and showing the device applied thereto.

Figure 3 is an enlarged fragmentary top plan view of the rear portion of the device.

Figure 4 is an enlarged fragmentary section on line 44 of Figure 3 and looking in the direction of the arrows.

Referring to the drawing in detail, and \vherein similar reference characters designate corresponding parts throughout the several Views, the letter A may designate a boot or shoe, en'ibodying a sole portion B and an instep C. The letter D designates the tread or ground engaging portion of the device, and Ev means for detachably securing the tread portion D to the sole nortion of the shoe A. Y

Referring to the tread portion or member D, and which is preferably stamped from sheet metal, the same embodies a sole portion 10 conforming to the configuration of the sole of a boot or shoe, and a rear or instep portion 11.- The sole portion 10 is formed at its marginal edge with an upturned flange 12 which engages each edge of the sole B and extends around the toe portion of the sole as clearly illustrated in Figure 2. The-instep portion 11 is formed flat, the flange 12 at each side of the sole portion 10 merging into the instep portion at the juncture of the; sole and instep portions. Ex-

tending around the marginal edges of the tread member D, is ametal binding13 which may be of U-shape in cross section, and which binding serves for covering the roughened edges of the tread member. This metal binding may be secured to the tread member in any suitable manner such as crimping or welding. This metal binding is desirable, since it is preferred that the .tr'ead member be stamped and then cut to the desired shape.

Referring to the specific formation of th sole and instep portions 10 and 11 respectively, the same consists of so forming the portion as to provide a plurality of transversely extending tread sections 14 arranged in staggered relation transversely of the tread member, and which tread sections are connected at their ends by diagonally extending web sections 15. As will be observed in Figures 3 and 4, these tread sections 14 are inclined pwardly and forward- 1y of the tread member, and that the diagonally extending web sections 15 extend rearwardly from the lower portion of one treadsection, upwardly to "the upper portion of its companion rear tread section. Thus it will be seen that the tread sections 14 which extend transversely of the tread member, are inclined upwardly and forwardly, while the diagonally extending web sections 15 extend in an upward and rearward direction thus providing a series ofground engaging transversely extending edges 17 arranged in staggered relation transversely of the treadmember. It will also be observed that by so inclining the tread sections ltforwardly and u )wardly, that when walking, ones foot will be prevented from slippmg rearwardly since the backward pressure of the foot Will cause the edges 17 to diginto the ice or snow for affording sufficient traction-to the wearer of the device.

Secured to each side and at the rear side of the instep portion 11, are bails 18, while the forward portion of the sole portion 10 has secured to the upper edge of the flange 12 transversely aligned bails 19, and which bails 18 and 19 preferably extend upwardly in substantially right angular relation with the major plane of the tread member.

Anchored at its opposite ends in the bails 18, isan ankle strap 20 provided with a buckle 21 for attachment of the strap for drawing the instep of the shoe.

In use, it will be seen that the flange 12 will engage the marginal edges of the sole l3, and that by so having the instep portion ll flat, when the strap 20 is drawn u tightly, the instep portion. It will yiel at its juncture with the sole portion 10, thus a1- lowing the instep portion 11 to be drawn into tight engagement with the instep C and allow for a suflicient amount of flexibility between the sole B and instep C.

From the foregoing description it will be apparent that a novel anti-slip attachment for footwear has been provided, embodying features for affording sufficient traction to the wearer when traveling upon slippery or ice covered surfaces, and which device is of such construction as to allow for proper flexing of the sole of the footwear to which the device is attached.

Changes in detail may be made to the specific form of the invention herein shown and described, without departing from the spirit of the invention or the scope of the following claims.

I claim:

1. A device of the class described eomprising a tread member formed with elongated tread sections extending in offset parallel relation to one another transversely of the member and connected by diagonally extending web sections, and means for attaching the member to the sole of an article of footwear.

2. A device of the class described comprising'a tread member having upwardly turned flanges at its i'orward portion and formed with a plurality of transversely extending forwardly inclined tread sections connected at their ends by diagonally extending web sections, and means for securing the member to the sole of an article of footwear with said flanges en'ibracing the l'narginal edges of the sole.

3. Tn a device of the class described, a tread member formed with a plurality of transversely extending forwardly inclined tread sections connected at their ends by rearwardly inclined diagonally extending web sections.

4. In a device of the class described, a tread member embodying a plurality of transversely extending tread sections disposed in forwardly and upwardly inclined relations, and diagonally extending webs connecting said tread sections and extending from the lower portion of the tread sections rearwardly and upwardly to the upper portion of the respective rear tread sections.
