Serial No. 621,124.

under the toe and heels of the hoof, respectively. The securing means comprises flexibly connected members adjustably secured in detachable relation on the wall of the hoof. The parts composing the tread portion are provided with means permitting limited relative adjustment, forming one of the essential features of my invention, whereby the normal length and wldth of the frame body may be increased to correspond to slight variations in the size and contour of the hoof.

Another feature of my invention is the provision of rigid calks which are removably mounted in position on the tread frame under the toeand heels of the hoof. These calks and the mountings provided therefor are so constructed that the calks may be removed and replaced by others, or, in event one side only is sufliciently worn to require substitution, may be reversed in position on the mounting, thus performing double service. 1 2

Having thus referred to the general character and purpose of my invention, I will proceed to describe a specific useful form of embodiment thereof, in connect-ion with the accompanying drawings, wherein Figure 1 is a side view showing the hoof provided with an ordinary horse-shoe, and

having my improved overshoe in position thereon; Fig. 2 is a bottom view of the same; and Fig. 3 is a face view of the toe calk and mounting therefor in the tread portion of my device.

The tread portion is shown as comprising a toe calk 1 and a heel calk 2 located under opposite ends of the hoof and removably mounted in their respective positions on a frame including a toe bar 3, a heel bar 4 and two side bars 5, 6, arranged under the margin of the hoof on opposite sides of the hoof and jointedly attached to corresponding ends of the toe and heel bars 3, 4.

The calks 1, 2, are shown as extending across the corresponding ends of the bottom of the hoof, and provided with a sharpened wearing edge of wedge-like formation and a dove-tailed body-portion which is-adapted to sli-dably engage oppositely arranged convergmg flanges 7 8, 8, provided on the lower side of the toe and heel bars, respectively. Said calks are secured in stationary position on the mountings preferably by means of headless screws '9, 9, 10, 10,

which are countersunk in the toe and heel bars, respectively, and engage tapped aper- I tures provided at predetermined points therein and in thecalks 1, 2.

The toe bar 3 is shown as arranged to engage the rear edge of the toe calk 11 of the shoe 12, which is usually provided thereon,

and operates as a fixed support preventing forward displacement of my device in conjunction with other means. I-further'preferably provide on the front edge of the toe bar 3, on opposite sides of the hoof, shoulders 13, 13, which project forwardly under the shoe 12 and operate as auxiliary sup ports to the tread portion and particularly serve to reinforce said bar when rearward pressure is applied thereto.

The toe and heel bars 3, 4, are shown as constructedwith extensions 14, 14,15, 15, respectively, provided on the inner sides thereof and arranged under the margins of the hoof on opposite sides of the same. Said extensions serve as connections for the side bars-5, ,6, whichare shown as movably secured thereto preferably by rivets 16, 16, 17 17, projected through coincident apertures provided therethrough, said rivets being represented as countersunk at their upper ends in the respective bar extensions and the side bars cut away on their upper sides at points of engagement with the calk extensions to receive the same, whereby the frame of the tread portion may preserve an even bearing surface for the shoe 12.

For the relative adjustment of the parts composing the tread frame and as a means for permitting a limited lateral and longitudinal extension thereof, I preferablyprovide short slots 18, 18, 19. 19, 20, 20. 21, 21, in the side bars 5, 6. and opening into the apertures receiving the rivets 16. 16. 17 17.. the slots being so arranged therein that the toe and heel bars 3, 4, may be spaced relatively farther apart, and likewise the side bars 5, 6.

The remaining portion of my device concerns the securing means whereby the thread portion is supported in stationary position under the hoof by members which engage the hoof only and have no positive bearing upon the skin or sensitive tissue of the foot or ankle. Said securing means preferably comprises a band disposed about the periphery of the hoof wall, having connections with the tread portion of each side of the hoof and tightening means for taking up the slack in the band. Said band is shown as an endless chain 22 circumventing the hoof wall, being seated well down in the notches formed by the heels of the hoof and the projecting ends of the shoe 12, and passing through metal loops 23, 23, 24, 24, which are secured through apertured lugs or extensions 25, 25, 26, 26, of the toe bar 3 and heel bar 4, respectively, on each side of the hoof. Said lugs or extensions 25, 25, 26, 26, are shown as forming shoulders at opposite ends of their respective bars which are adapted to engage the sides of the shoe l2 and serve to revent lateral movement of the tread portlon when in position on the hoof. Said band 22 is preferably masked or cushioned at the heel by a covering of fabric 27, of any suitable material, to pre vent the chain from working forward and wedging the shoe from the hoof, while the slack in the, band is taken up preferably by means of a tension-band, shown as a leather strap 28 passing diagonally across the toe of the hoof and connected to the band 22 on each side of the hoof at points preferably forward of the region of maximum width thereof, and also at a central point over the toe, suitable loops 29, 30, being adopted at the several points of connection which permit movable engagement therewith and adjustment of the strap 28. The strap 28 is preferably doubled through the attaching loops 29, 29, and the ends secured together by a buckle 31, thereby increasing the tightening effect of a pull on the end of the strap.

As the band 22 passes loosely through the tread connections 23, 24, it will be observed that it is not positively anchored at any point and the tension thereon exerted by the tightening of the strap 28 causes all slack to be taken up at every point in the band 22, drawing up the tread port-ion in close stationary engagement with the bottom of the shoe 12 and automatically distributing the tension evenly at all points around the hoof.

It will be understood that terms descriptive of the material herein stated as used in the construction of the bands 22 and 28 are not intended as words of limitation, and

that any suitable material or slight modifications in the construction thereof, as well as in other parts of my device, may be adopted without departing from the spirit and purpose of my invention.
