HORSESHOE CALK.

UKED T PETER LA PLANT, OF DULUTH, MINNESOTA, A$SIGNOR 0F ONE-HALFTO AUSTIN LATHERS, DE DULUTH, MINNESOTA.
v HORSESI-IOE-CALK.
Specification of Letters Patent.
Patented Oct. 15, 1918.
Application filed May 13, 1918. Serial No. 234,128.
To all whom it may concern:
Be it known that 1, PETER LA PLANT, 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 relates to horseshoe calks and has for it principal object to provide a novel form of calk, the ground-engaging blade of which will wear more evenly and have better frictional contact with the surface engaged than the common horseshoe calk.
Other objects and advantages will appear in the further description of the invention.
Referring to the accompanying drawings forming part of this application and in which like reference characters indicate like parts Figure 1 is an under plan view of a horseshoe fitted with my improved calk and illustrating a preferred arrangement of same.
Fig. 2 is an enlarged front elevation of one of the calks.
Fig. 3 is a rear elevation of Fig. 2.
Fig. 4 is a side elevation of a calk.
Fig. 5 is a plan view frointhe under side.
1 represents the slightly tapered cylindrical shank of the calk which is similar to others of like character and upon which is integrally formed a horizontally-elongated substantially rectangular-shaped groundengaging blade comprising the side members 2-,bcentral \l-shaped member 3, and tapered ri s 4.
I speak of the flat face of the blade as being the front as I prefer always to place the toe calks in the shoe 5 with that face forward, which results in as long and straight line of engagement with the traversed surface as possible and at a time when the least number of calk on the foot in ques tion are in engagement with the surface, as for example, when a horse is pulling hard and forcibly engaging the ground with his toes prior to placing the foot down flatly. When the latter position occurs, and under ordinary circumstances, the more surface of the calk engaging the ground the better and then is when the ends of the ribs and the V-shaped member come into engagement with the ground.
The office of the V-shaped portion, apartfrom strengthening the blade, is to improve the grip thereof on the ground and prevent it sliding laterally as is also that of the ribs 4.
The V-shaped member 3 and ribs 4: also tend to bring the bearing surface of the calk blade more directly across the center of the shank 1 which improves the durability of the calk.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. A calk of the character described having in combination with a suitable shank, a blade which in elevation is of horizontallyelongated rectangular form, a central V- shaped vertically disposed member in the blade, and two rectangular shaped ribs, one upon either side of the V-shaped member.
2. In a horseshoe calk, the combination with a suitable shank of a blade the major portion of which is of V-shape centrally of the shank and having laterally projecting wings at an angle to the walls of the V-shape, and vertically-disposed rectangular-shaped ribs centrally of the wings.
In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
PETER LA PLANT.
