, To all whom it may concern.'

Be it known that I, JOHN MGCANNA, a citizen of the United States,'residing at Ontonagon, in the county of Ontonagon and State of Michigan, have'invented a new and useful'Tread for Footwear, of which the following is a specification.

This invention relates to footwear, and particularly to shoes, it beingr the primary object of the present. invention to provide a novel form of tread for rubber shoes, in order to eifectually prevent slipping on snow and ice.

This invention is adapted particularly for use in connection with `ilurnbermens shoes, but it is understood that the same has a wide range of application, aswill be apparent. p

This invention contemplates the production of a tread for a shoe which shall be easy to manufacture, which shall be inexpensive in its production, which shall be substantial and durable, and which shall eiectively revent slipping, as well as being convenient and comfortable, in its use.

It is the object of the present invention, to avoid the use of leather or other pieces in the construction of the sole and heel of the tread, which pieces Serve to weaken the solo and heel so that cracking or breaking thereof is rendered more liable, and-for the Jfurther reason, that said pieces tend to shrink and swell independently so as to cause the -warping or /unshaping of the tread, which is objectionable.

The present invention has for a further object, to provide a tread of the character indieatedfwhich shall be devoid of nails, or other metallic securing members, the absence ot which has the edect of increasing the resistance against conduction, so that the tread gives proper protection against cold, as it would not otherwise furnish in the presence of nails .and the like.- The preslence of nails und similar securing members would also turd in tear the solo and heel and thus provide leaks and other disadvantages which the present invention aims to overcome.

A still further object of the present invention is to provide a tread molded from rubber andL comprising integral heel and sole portions, and integral means for preventing slipping.

TWith the foregoing and other objects in view, the present invention resides in the novel construction, combination and. arrangement oi' parts hereinafter set forth and claimed, reference being had to the ac; companying drawing, wherein the invent-ion has been illustrated in its preferred embodi-` ment, and wherein- I Figure 1 is a bottom view of the tread of -a shoe constructed in accordance with the present invention. Fig. 2 is a side elevation thereof. Fig. 3 is a section taken on the line- 3-3 of Fig. l.

Referringspecitically to the drawings, the numeral 4 designates the tread comprising the sole portion 5 and the heel port-ion 6, which are of approximate equal thickness throughout and are of a thickness to suit the circumstances. The tread is also suitably curved to coliform to the foot. of the wearer, 'asl will be apparent.

The heel portion 6 is provided with an integral depending transverse rib 7 at its front end and with an integral depending transverse rib 8 at and forming a part of the rear end of the heel, the ribs 7 and 8 being of considerablewidth and being spaced apart as will be observed in the drawing.

The sole portion 5 isprovided with a pair ot integral depending'juxtaposed transverse strips 9, which are arranged directly in rear and in front of the point l0 or the sole portion on which the ball ot' the foot' is adapted to rest, the ribs 9 also being of considerable width. Y

ln the formation of the tread, the same is L molded in a suitable former mold, the tread, -and\ ribs beiney grooved, serrated or otherwise roughened, as is customary. It ma be stated at this point, that the pair of ri s 9 on the sole portion are essential, but if desired, more than two of the ribs may be provided. From the foregoing, taken in connectio with the drawing, the advantages and capabilities of the presenttread will be apparent., and it will he observed that the objects aimed at have beencnrried out. The tread in being constructed of an integral piece of rubber will not warp, swell, shrink, or otherwise become distorted as would be the ease it' the tread embodied leather or other pieces, and nails or other securing;r members. The application of the tread to rubber shoes or other footwear will be apparent, itbeing noted that the ribr'a at the front and rear ends of the heel will convenience the use of a shoe embodying the present tread and that the ribs 9 are arranged directly in front and rear of the point of the sole upon Which the ball of the foot is designed to rest, to permit the sole to bend or fiex between the ribs 9. The ribs are all ot' considerable widths so as to adapty a shoe embodying the present tread for ordinary use, and the ribs are also of sutlicient. depth to properly sink into the snow for preventing slippine.

IIn practice, it may be desirable to slightly shift the particular' position of the various ribs, it being understood, thereiore, that the particular arrangement of the var1ous ribs may be altered as is deemed desirable or beneficial.v l

Having thus described the invention, what is claimed as new is A molded shoe tread comprising integral Sole and heel portions of approximately equal thickness throughout, the heel portion having,r an integral depending transverse rib ot' comparative large width at its front end, and an integral depending transverse rib of comparatively large width at and forming a part of the rear end thereof, and the sole )ortion havin Y a )air of inteo'ral de )cnd- D D mg transverse ribs of comparatively large widths directly in front and in rear ol the point of the sole portion on which the ball of the foot is designed to rest.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.
