REMOVABLE GALK FOR HO-RSESHOES Specification of Letters Patent.

Patented Feb. 3,1914.

Application filed February 7, 1913. Serial No. 746,770.

To all whom it may concern Be it known that I, THoMAs H. IVARNER, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Removable Calks for 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 appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in removable calks for horse shoes and consists of a means for removably attaching calks to shoes and in making said means adjustable to fit shoes of difierent sizes.

One of the objects of the invention is to provide a device which shall have a double clamping effect, making the liability of its becoming loose upon the shoe practically negligible.

Another object of the invention is to utilize the calk proper as one of the clamping elements.

A third object is to make the clamp adjustable for shoes of different sizes.

Other objects will appear hereinafter as I proceed with the description of that embodiment of the invention which, for the purposes of the present application, I have illustrated in the accompanying drawing, in which:

Figure 1 is an under face view of a horse shoe provided with my improved removable calks. Fig. 2 is a cross sectional view taken upon the line 22, Fig. 1. Fig. 3 is a cross section upon the line 33, Fig. 1. Fig. 4 is a detail perspective of the calk. Fig.

5 is a detail perspective of one of the clamp ing elements. Fig. 6 is a detail perspective of another of the clamping elements.

The same reference numerals refer to like parts in each of the views.

In the drawing, which forms a part of this specification, the numeral 5 refers to a horse shoe of ordinary and well known form. IVhen the calks which are integral with the shoe become worn down and consequently useless as a preventive against slipping, new sharp calks made in accordance with my invention may be applied without removing the shoe from the horses foot and without tools, other than a wrench.

My invention includes L-shaped members 6 and 7 both of which upon the inner side of the upright portions are serrated at 8, in order that the'serrations may bite into the metal of the horseshoe when the members 6 and 7 are clamped together. Lips 9 extend inwardly from the upper extremities of the upright portions of each member, the lips 9 being adapted to engage the upper surface of the shoe and thus assist in maintaining the calk in place.

The horizontal portion of the member 6 has a threaded shank 10 preferably integral therewith, and is also provided with a threaded perforation 12, the purpose of which will be described present-1y. The upright portion of the member 7 below the serrations 8, is perforated at 13, the wall of the perforation being smooth. The horizontal portion of the same member has a slot 14 therein, running longitudinally, said slot being slightly wider than the diameter of the threaded opening 12. The perforation 13 is of sufficient size to receive the shank 1O loosely, when the members 6 and 7 are assembled, a nut 15 being then threaded upon the shank 10 and caused to clamp the parts together after which a locknut 16 is threaded upon the shank to bear against the nut 15. I

The calk 17 has the usual wedge shape with a flat surface 18 upon its upper side. A. shank 19 preferably integral with the calk extends upwardly from the surface 18, the shank 19 being of a size to slide freely in the slot 14 but having threads adapted to fit those of the perforation 12. When the device is to be applied to a shoe, the calk 17 is turned anti-clockwise until the horizontal portions of the members 6 and 7 are free to slide readily upon each other when the device is placec upon the shoe and the nuts 15 and 16 tightened. The calk 17 is then grasped by its flat sides and screwed up until the horizontal portion of the member 7 is firmly clasped between the horizontal portion of the member 6 and the flat upper surface 18 of the calk 17. Of course, if preferred, the shank 19 of the calk 17 need not be inserted in the perforation 12 of the member 6 until the members 6 and 7 have been secured by the nuts 15 and 16.

It will be apparent that when the calks 17 have been worn down considerably, new ones may be substituted even without the removal of the members 6 and 7 from the shoe, which is a very important feature of my invention.

It is obvious that minor chan es in the details of construction may be made without departing from the spirit of my invention as set forth in the appended claim.

I claim as my invention:

In combination, two L-shaped members, the horizontal portions of which are arranged to extend toward each other, and the upright portions of which are adapted to grasp a horseshoe, the horizontal portion of one member lying upon the horizontal portion of the other member, the lower horiceive said shank, and means for drawing 25 toward each other the upright portions of said L-shaped members.

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

THOMAS H. WARNER.
