MEANS FOR FASTENING HORSESHOES.

Specification of Letters Patent.

Application filed June 20, 1906.

Patented Feb. 12, 1907.

Serial No. 322.623.

To (all whom it may concern:

Be it known that 1, JOHN P. OBRIEN, a citizen of the United States, residing at Castle ltock, in the county of Douglas and State of Colorado, have invented certain new and useful Improvements in Means for Fastening Horseshoes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it app ertains to make and use the same, reference being had to the ac companying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in means for fastening shoes to the hoofs of horses, my object being to provide a device whereby the shoe is readily detachable for the purpose of resting the feet of the horse during the night, for lnstance.

In my improved construction nails of the horse and clenched in the usual way. The lower extremities or heads of these nails are enlarged and tapped to form threaded recesses adapted to receive screws passed through the horseshoe and engaging the threaded recesses of the nails. In removing the shoe it is only necessary to take a screw driver and take out the fasteningscrews. The nails of course remain in place. The reattaching of the shoe is equally easy and can be performed by any one.

Having briefly outlined my improved construction, I will proceed to describe the same somewhat more in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is an underneath view of the hoof of a horse, showing a shoe applied in accordance with my invention. Fig. 2 is a side elevation of the same, partly in section. In this case the shoe is shown in its natural position when the foot of the horse engages the ground or other surface beneath him. Fig. 3 is a detail view of my improved fastening means, showing the nail and its cooperating screw. In this view the two members are detached. Fig. 4 is a view taken at right angles to Fig. 3, showing a screw inserted in the threaded recess of the nail. F:' g. 5 is a sectional view illustrating another form of construction The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a horseshoe, which may be of any oremary construction, the only ifference being that the holes at their outer extremities are enlarged to receive V screw-heads, whereby the latter may be countersunk when the shoe is applied to the hoof of the animal.

My improved fastening means conists of a na;.l member 6 and a screw member 7. The nail member 6 is provided with a head 6, which in this case is shown cylindrical inform, though this particular form is not absolutely essential. In this head portion is formed a threaded recess adapted to receive the screw 7. The part 6 of the nail member is formed thin and tapering from the shoulder 6 of the head to the point.

It must be understood that the special form illustrated in the drawings is not essen tial, since the nail, so far as its general construction is concerned, may be made in many different shapes, the only indispensable feature being that it shall be provided with a head member having a threaded recess to receive the fastening-screw. It is evident that the reverse of this construction might be employedthat is to say, the screw might have the interiorly-threaded recess and the nail might have the threaded shank, as shown in Fig. 5, though the form illustrated in the principal views is believed preferable, since if the nail were provided with a threaded shank the thread of this shank would possibly be upset or injured by the blows of the hammer in driving the nail into the hoof. is evident, however, that the scope of the in vention is sufficient to include both of these forms of construction.

In Fig. 5 let the reference character 6 represent the threaded shank of the nail, while the reference character 8 designates the hollow screw or the screw provided with the interiorly-threaded recess adapted to cooperate with the threaded shank to form the shoefastening means.

In applying the shoe by the use of my im proved fastening means the hoof 1s first shaped or trimmed and the shoe formed to fit the hoof. The shoe is then applied to the hoof and a pointer inserted through each nail-hole, form ng marks for the nails. By the use of a small auger or hit holes are formed in the hoof to receive the heads 6 of the nails. The nails are then driven into the hoof until the heads 6 are embedded in the Itgo recesses formed, the outer extremities of the said heads being flush with the bottom of the hoof. The shoe is then put in position and the screws passed through the shoe and inserted in the threaded recesses of the nails. The points of the nails are then bent down or clenched on the outside of the hoof, whereby tllie fastening devices are secured tightly in p ace.

In securing the shoe by the means shown in Fig. 5 the same steps would be followed. In this case it would of course be necessary for the holes in the shoe to be formed somewhat larger in order to receive the enlarged hollow shank of the screw.

Having thus desoribedmy invention, what I claim is 1. Means for fastening horseshoes, comprising two detachable members, one consisting of a nail adapted to be applied directly to the hoof of the animal, while the other consists of a screw adapted to pass and a shoe member consisting of a screw, one

of the members being provided with a threaded recess and the other member with a threaded shank adapted to enter the said reccss.

3. Means for fastening horseshoes, comprising a hoof member consisting of a nail, having a head provided with a threaded recess, and a shoe member comprising a screw having a shank adapted to enter the threaded recess of the hoof member.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN P. OBRIEN.
