JULIUS WOLFF, OF GREENPOINT, NEW YORK.

HORSESHOE.

Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed April 28, 1905. Serial No. 257,799.

To all wia/071e it may con/cern: p

Be it known that I, JULIUS WOLFF, a citizen of the United States, residing at Greenpoint, in the county of Kings and State of New 5 York, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

The present invention relates to improvements in horseshoes, the main object being to facilitate the substitution and interchangeability of toe and heel calks, avoiding the necessity of removing the shoe.

With the above and other purposes in view the improvements involve novel attachment means for the calks to permit the easy and positive attachment of toe and heel calks to the shoe and to enable the toe and heel calks when worn out to be easily removed and replllaced by others -without the removal of the s oe.

A further improvement of the present invention consists in arranging pads of soft lead between the calks and the shoe in such a manner that the same will not only coact to neutralize different sensations sustained by the hoof, but will serve also to cushion the hoof generally and to strengthen the connection of the calks with the shoe.A

In order to make my invention more clear, I have illustrated the same in the accompanying drawings, in which- Figure 1 is an inverted plan view of ahorseshoe embodying one form of my invention. Fig. 2 is a longitudinal view thereof; Fig. 3, a longitudinal sectional view thereof through line :1; of Fig. 1. Fig. 4 is a cross-section through line y y of Fig. 1. Fig. 5 is a partial longitudinalsection through line z z of Fig. 2.

With reference to the drawings, 1 is the shoe proper, which may be of any suitable material and of any desirable type and size and which is not equipped with the integral toe and heel calks. In the toe portion of the shoe 1 and on the under side thereof a rectangular and oblong excavation 2 is made transversely thereto. This excavation does not extend throughout the entire thickness of the shoe, but only to a certain depth, so as to leave sufficient material above it in order not to weaken the shoe. At each side of the excavation 2 threaded holes 3 4 are provided in the shoe 1. The toe-calk 5, which is an oblong block of steel or like material, can have its tread portion designed for any particular character of road. As shown in Fig. 3, the same widens in cross-section toward the top and is provided with an upwardly-extending rectangular and oblong tongue 6, adapted to tightly fit in the excavation 2 of the shoe. At each side of the said tongue 6 a flange 7 is formed, in which holes 8 are provided to receive screw-bolts 9, which are ada ted to screw into the threaded holes 3 4 of t e shoe and by means of which the calk 5 is secured to the shoe. A pad 10, of soft lead or the like, which is correspondin ly recessed in its center for the passage of t e tongue 6, is adapted to be fitted around the latter on the upper surface of the calk to rest between the calk and the shoe.

The heel-calks 11 consist of s uare steel blocks that are tapered toward t e bottom and are provided at their top with conical pivots 12. Corresponding bores 13 are made at the heel extremities of the shoe to receive the conical pivots or rojections 12 of the calks. In the exteriorllateral surfaces of the shoe at each heel extremity are thread-holes 14, extending inward transversely to the conical bores 13, which holes are adapted to receive small screw-bolts 15. The conical piv ots are flattened at a part 16 opposite the threaded holes 14, Fig. 5, against which flat parts the inner ends of the screw-bolts are adapted to rest when the latter are sufliciently screwed in, so that the calks will be secured in proper position and be prevented from turning around. Arranged between the upper surfaces of the calks and the shoel are lead pads 17, similar to that at the toe end of the shoe. `When the calks are Worn out after a certain time of use, they can be easily removed and replaced by new ones. This form of my invention Iprefer to use forlight travel.

I am aware of the number of patents allowed for horseshoes, but I found that none of them involves the novel idea of the particular interchangeable attachment of the calks, as in my invention.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination with a horseshoe, of detachable toe and heel calks, bores or grooves in the under surface of the shoe adapted to engage projecting parts of the calks,and soft-lead IOO pads fitted between the ealks and the under In testimony whereof I afflx my signature surface of the shoe, said pads being adapted in presence of two Witnesses. to tightly incase the projecting parts of the ealks and to fill the Worn-out bores or grooves 5 to strengthen the attachment of the oalks to Witnesses:

the shoe, substantially and for the purpose MAX D. ORDMANN, as speeied. EsTELLE V. WALE.
