F. .GENECAND SHOE NAIL FOR MOUNTAIN BOOTS Filed May 9, 1934 Patented Apr. 9, 1935 V 1 UNITED stars-s *aP AiZEN'ET' SFFFieE 1,997,110 SHOE-NAIL FOR MOUNTAIN BOOTS This invention relates to a shoe-nail for mountain boots, comprising in combination a body which has the general shape of a T, to be placed under the sole of the boot on the edge'of the.

latter, and the transverse branch of which embraces in a general manner the form of that edge;

at least one elongated claw located on the said from that of the first claw and are separated from the latter by a distance at least equal to the height of thehigh'est of the threeclaws; the body and the claws being made of a single piece of metal.

On the annexed drawing is shown, by way of example, one example of the shoe-nail, wherein Fig. l is a front view.

Fig. 2 is a cross section on line 11 11 of Fig. 3.

Fig. 3 is a view from below. r

Fig. 4 relates to a detail.

The example shown is disposed on one of the sides of the sole 1) and is made of one piece of metal, of hardened steel for example, and in plan having the general shape of a T. The medium branch 0 is trapezoidal in shape and has on each of its oblique sides a claw d or 2 almost at right angles with the branch 0 and directed downwardly; in each claw are cut out two large notches 9 thus, creating three teeth 7. The two parts 71,2, of the transverse branch h-i each bear on their exterior edge a claw y or it which is almost perpendicular to the part it or i, directed downwardly, and in which are cut out two large notches I, thus creating three teeth m. Seen from above, the claws d, e, on the one hand, and the claws 7', k, on the other, are thus very difierently directed and are almost at right angles to aneanother.

Moreover the claws d, e diverge slightly from the exterior of the sole to the interior, as they are on the oblique sides of the branch 0.

Seen from the side, the branches 0, h, 2' are curved with a convexity which is turned downwards and which enables the branches to em- 45. brace the convexity of the sole 2;. The exterior edge of the branch hi and the claws 7, it have likewise, seen from above, a curve enabling them to embrace in a general manner the curve of the edge of the sole b. 1 The claws d, e are not so high as the claws 9' or It, so that the teeth of the different claws may be approximately of the same height. The minimum distances between the claws of different directions are greater than the heights of the different claws. In the same way the minimum distance between the two claws d,

e'is greater than theheight of each of the latter.

Between the two claws 2c there-is a paw n directed upwards, rising along the sole b and having at the top of the latter a hook 0 bearing on the upper surface of thesole b.

The fixation of the example shown, to the sole 1) is eiiected by means of staples 2 which before use are 'U-shaped, andthe lateral branches of which are. parallel. The latter are striated at 4 and are beveled at 5 at their free ends according to planes diverging from the median branch 6. To fasten the shoe-nail or tip to the boot, the lateral branches 3 of thestaples 2 are passed through holes I of the body a and of hook o of the tip, then force is exerted on'their transverse "from coming out of the sole under the' action of the forces to which the staples are-subjected. Theholesfi, provided in the body are almostpe're pendicular to those bodies, while the holes 1 made in the hook o of thepaw n are oblique relative to the latter sothat the staples penetrate into the sole 1) and their branches 3 run no risk of coming out on the edge of the sole owing to bad direction of driving. v I Grooves H] of more or lessdepth are provided in the exterior surfaces of the body a and hook 0, end perpendicularly in the complementary grooves 9, and form passages enabling the point of a tool to be inserted under the transverse branch 6 of the staples 2 in order to extract the latter.

The height of the claws d, e increases from the middle of the sole to the lateral edge of the latter so that the tops of the teeth must be almost on a rectilinear lineparallel to the ground, in

other words at the same height. The said line joining the tops of the teeth can also have any other desired contour.

Examination of the drawing will show that the shoe-nail or tip is very firmly fixed to the sole by means of the staples 2 and the paw n, it is kept in place in the required position by the staples 2 and the paw n despite the large forces to which it is subjected, it is however fastened to the sole 1) only at its median part so that the parts 71., z of its transverse branch can adapt themselves to a certain extent to the ground. The claws d,.e and 7', k of the tip penetrate into the ground in-quite different directions and this claws j, k grasp the groundon the edge of the sole 1), while the claws d, e are sufficiently removed both from each other and from the claws 7', k that they do not prevent one another from taking a good hold inthe ground. The slight divergence in the .claws'd, e allows the earth and/or the stones, which might be momentarily caught in them, to come out easily, while the claws 7', k protect theunder edge of this sole and the paw n protects the edge of the sole. The shoe-nail may be fixed to the heel aswel as tothe sole of the boot, and the number of nails used on the boots may vary. 7

WhatIclaim is: l. A shoe-nail for mountain boots, comprising in, combination, a body having the general shape of a T adapted to be placed under I the sole. of the boot on the edge of the latten'and' the transverse branch of which embraces in a general manner the contour of said edge, at least one elongated claw located on said transverse branch two elongated claws located on the longitudinal branch of said body' and consequently having quite different directions from'that of said first claw, and being separated both from the latter and-'from each other by a distance at least equal't'o the height of the highest of the three claws, a fixing paw adapted to pass along the edge of the sole and provided with a hook bearing onthe upper sur- .face of said sole and having'at leastone pair or" holes adapted to receive the lateral branches of a U-shaped aflixing staplelwhich penetrate into the sole, the holesbeing oblique relative to the hook so that the lateral branches may readily enter the interior of the sole, while the transverse branch rests on the shoe-nail, the body,'claws, paw and hook being madeof afsingle piece of metal. a I

2. A shoe-nail for mountain boots, comprising in combination, a body which has the general shape of a T, intended to be placed under the sole of the boot on the edge of the latter, and the transverse branch of which embraces in ageneral staple, the lateral branches of which penetrate into the sole, and being provided with a groove between the holes of a pair of holes so that the transverse branch of the staple can be at least partially received in said groove, the body and claws being made of a single piece of metal.

,3. A'shoe-nail for mountain boots, comprising in combination, a body having the general shape of a T, adapted to be placed under the sole of the boot on the edge of the latter, and the transversebranchof which embraces in ageneral manner the contour of said edge, at least one elongated claw located on said transverse branch, two

elongated claws located on the longitudinal branch of said body and consequently havin quite. different directions from that of the first claw, and being separated from the latter and from each other by a distance at least equal to the height of the highest of the three claws, and the shoe-nail having at least one pair of holes adapted to receive the lateral branches of a .U-shaped afixing staple the lateralbranches of which penetrate into the sole, and being'provided with agroove'between the holes of a pair of holes so that the transverse branch of the staple can be at least partially received insaid groove, said shoe-nail being .further provided with a passage ending in the groove so thata tool may-be introduced under the transverse branch to extract the staple, the body and'claws being made of a single piece of metal. u r
