ADOLPH 0. EVENSON, 0F DULUTH, MINNESOTA.
HORSESHOE-CALK.
Specification of Letters Patent.
Patented May 8, 191?.
Application filed December 26, 1916. Serial No. 138,973.
1 0 all whom it may concern:
Be it known that I, ADOLPH O. EVENSON, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Horseshoe-Calks, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention consists of certain new and useful improvements in horse-shoe calks and relates particularly to what are known as detachable calks. Such calks are usually formed with cylindrical tapered shanks which are designed to be inserted within similarly tapered holes in the shoe to which the calks are applied and the calks are securely held within the shoes by means of frictional contact therewith.
Shoulders are usually formed at the junction of the blade of the calk with the shank and when the latter is home within the hole of the shoe, the shoulders are spaced a distance from the face of the shoe for the insertion of a wedge shaped instrument for extracting the calk.
In the ordinary calk these shoulders are comparatively narrow and subject to considerable wear during the latter part of the life of the calk and if badly worn, are not sufficiently strong for the purpose of extraction, as before related. Under these conditions they frequently break off and otherwise cause considerable annoyance.
One object of my present invention is to overcome such weakness of shoulder.
Another object is to provide an improved shape of calk and one that will wear longer and more evenly than at present in use.
Still another object is simplicity and cheapness of construction.
In the accompanying drawings forming part of this application and in which like reference characters indicate like parts.
Figure 1 is a side elevation of my improved calk.
Fig. 2 is a front elevation of same, and
Fig. 3 is a top plan view.
1 represents the shank of the calk which is of cylindrical shape and slightly tapered inwardly from the junction with the blade to the opposite end thereof and which is the usual form of the shank of the common detachable calk.
Upon the shank and formed integral therewith is the traction blade 2, the face of which comprises two flat planes 3 and 4: forming an obtuse angle therebetween. The plane 3 being in a direct line with the center of the shank 1, and the plane 4: being inclined therefrom to a point beyond the edge of the base of the shank, the point of intersection of these two planes being a distance above the connecting line of the blade with the base, approximately one half that of the height of the plane 3. The opposite or rear face 5 of the blade comprises one continuous plane extending from the extreme outer end of the blade to the line of the base to a point equally distant from the base of the shank to that of the plane 4.
The base of the shank is rectangular shape and the sides of the blade are straight and parallel, they also extending beyond the outermost edge of the base of the shank a distance substantially equal. to that of the two opposite edges. Thu-s I have provided a calk which may be worn two thirds of the entire height of the blade without altering the proportionate strength of base thereof to the shank and one that may be engaged from any angle by the extracting tool with equally good results and the extreme tractive edge 6 of the blade being in direct line with the center of the shank of the calk answers the most practical purposes of insertion when struck by a hammer, as the impinge ment occurs directly in line therewith and insures a perfect seating of the shank which is not the case with a calk having the blade offset from the center. The tendency to remain in place and of evenness of wear is also improved by this construction.
Having thus described my invention what I claim and desire to secure by Letters Patent, is:
1. A horse-shoe calk of the character described, comprising in combination a cylindrical shaped tapered shank and a rectangular shaped traction blade' formed integral therewith, the major portion of one face of which blade is straight and in a direct line with the center of the shank, and the opposite face inclined from the point of the blade to the base thereof.
2. A horse-shoe calk of the character described, comprising in combination a cylindrical shaped tapered shank, a rectangular shaped traction blade formed integral therewith, the major portion of one face of which blade is straight and in a direct line with the center of the shank, the opposite face he ing inclined from the point of the blade to the base thereof and said base projecting beyond the shank on all sides thereof.
3. A horse-shoe calk comprising in combination a tapered cylindrical shank and a rectangular shaped blade having one face,
the major portion of which is vertical and nation a tapered Eylindrical shank and a rectangular shaped blade, the major portion 15 of one face of the blade being vertical, flat and in direct line with the center of the shank and the opposite face inclined in a single plane from the apex of the blade to the base thereof.
In testimony whereof I hereunto affix my signature in the presence of tWo Witnesses.
