HORSESHOEHCALK.

Speccaton of Letters Patent.

Patented Feb. 12, 1907.

Application filed April 14, 190G- Seriai I\Ion 311.726A

o all 1071/0777/ t muy conceive:

Be it known that I, RICHARD N. GOODWIN, a citizen of the United States, residing at \Vichita, in the county of Sedgwick and State of Kansas, have invented new and useiul Improvements in Ilorseshoe-Calks, of which the following` is a speciiication.

My invention relates to horseshoe-calks, and its primary object is to provideI a coiled- Io spring calk which is adapted' to take up and dissipate jars resulting from the impact of a horses feet with the roadway and which is adapted to engage firmly with the roadway to prevent the horse from. slipping.

A further object of the invention is to provide a calk which may be easily and quickly applied to and removed from any construction of shoe, one which is simple and durablc, and one which may be manufactured and sold at a comparatively low cost.

rThe invention consists in the construction, combination, and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, wherein- Figure l is a bottom plan view of a horseshoe provided with my improved calks. Fig. 2 is view in side elevation thereof; and Fig. 3 is a central longitudinal section of one of the heel portions of the shoe, illustrating the manner in which the calk is applied.

Referring to the drawings by referencenumerals, l designates a horseshoe of the usual construction and form, and 2 my iinproved calks secui ed to the heel and toe portions thereof. The calks consis ts of spirallycoiled springs having the under surfaces oi their convolutions roughened. The convolutions of the calkdiave such relative diameters that they are adapted to fit one within the other and occupy a-common plane when the calks are compressed, whereby to provide roughened treads. The ends of the uppermost and smallest convoiutions of the calks are disposed vertically and centrally and threaded to provide attaching elements 3. The threaded attaching elements 8 are adapted to engage in threaded sockets 4, located in the under surface of the shoe l.

It should be apparent from the above de scription, taken in connection with the ac- 5o coinpanying drawings, that the calks are adapted to take up and dissipate all shock resulting from the impact of the horses feet with a roadway and prevent the shocks thus occasioned from being carried to and injuring 5 5 the limbs of the horse. It also should be apparent that as each convolution of the calks engages the roadway the horse is thereby prevented from slipping. When the under surfaces of the convolutions wear 6o smooth, the same may be again roughened by means of a :[ile.

Having fully described and illustrated my invention, what I claim is 1. T he combination with a horseshoe, of a spirally-formed sprin0calk adapted to be secured to the shoe and having the under suriaces of its convolutions roughened, the convolutions being adapted to occupy a common plane to provide a roughened tread 7o when the calk is compressed.

2. The combination with a horseshoe, of a spirally-formed spring-calk having the under surfaces of its convolutions roughened, the convolutions being adapted to fit one within the other and occupy a common plane to provide a roughened tread when the calk is compressed.

3. The combination with a horseshoe provided with a threaded socket, of a spirally- 8o formed spring-calli having the under surfaces of its convolutions roughened, the convolutions being adapted to occupy a common plane to provide a roughened tread when the calk is compressed, the extremity of theup- 8 5 permost convolution being projected centrally and vertically and threaded for engagement in the socket of the shoe.

In testimonywhereof I aflix my signature in presence oi' two witnesses.

RICHARD N. GOODWIN.
