Improvements in or relating to Horse-shoes.
I, SAMUEL ALBERT OWEN, of West Berkeley, near San Francisco, in the
County of Alameda, in the State of California, at present residing at Societetshuset,
Helsingfors, Finland, in the Empire of Russia do hereby declare the nature of my
invention to be as follows:-
This invention relates to the method and means of applying brods, calks or
roughing pieces (hereinafter referred to as "calks ") to horse-shoes and to the shape
of the shoes, and will best be understood by reference to the accompanying drawings
in which
Figure 1 is a plan of the underside of a horse-shoe constructed according to my
invention.
Figure 2 is a central section on the line y, z of Figure 1 and
Figures 3, 4 and 5 are respectively side and end elevations and a plan of the
underside of a calk detached from the shoe.
Figures 3, 4, and 5 are drawn to a scale larger than that to which Figures 1
and 2 are drawn.
Similar letters of reference indicate like parts throughout the drawings.
A is the body of the shoe which may be of the ordinary construction, except as
hereinafter specified, and which is formed with toe and heel projections A', A.
Each of these projections is formed with a taper dovetail groove a, and against the
toe piece A is a hole c through the shoe, into which the tongue 6 of the calk enters
when it is bent over as hereinafter described.
B, are the calks which are tapered and dovetailed to correspond with the shape
of the grooves a into which they are adapted to fit. The ridge b of each calk B
is, preferably, formed with one or more notches and each calk is, moreover,
provided with a projecting tongue extending beyond its smaller end as shown
most clearly in Figures 3 and 5.
In applying the calks to a shoe each is inserted into one of the grooves a, the
smaller end first, and pushed or driven in as far as it will go; the tongue & is then
hammered or otherwise bent over out of line with the base of the calk or upwards
towards the horse's hoof, in the manner shown in Figure 1 and in dotted lines in
Figures 2 and 3 when it will be firmly secured in position.
To remove one of the calks B in order to substitute a new one for one which is
worn, or for any other reason, the calk is to be driven or punched out, the tongue b
breaking off or giving way.
In a horse shoe, as ordinarily constructed, the heel-pieces, or rear projections A',
are practically perpendicular to the back ends of the shoe, but according to my
invention, construct the shoe with the projections A at a considerably modified
angle as shown in the drawings so that the front and back projections B are
substantially, or nearly parallel to each other, for the express purpose that the horse
should not be able to kick his own legs or hurt himself.
The shoe A is formed in other respects in the usual manner with holes a' for the
insertion of the nails for securing it to the horse's hoof and may be made of flat or
grooved iron or steel or of other suitable material.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is :
1. The method of securing a calk in a horse-shoe by forming the calk taper and
dovetail and with a projection or tongue 62, and inserting it into a corresponding taper
and dovetail groove in the shoe and bending over the tongue substantially as
hereinbefore described and illustrated in the accompanying drawings.

page_text: 2. In a horse-shoe, forming the heel-pieces, or rear projections, substantially, or
nearly parallel with, the front one and with each other for the purpose and
substantially as hereinbefore described and illustrated in the accompanying
drawings.
3. In a horse-shoe the combination of dovetailed and tapered grooves a, the
calks B of corresponding section and taper, having a projecting tongue 62, by the
bending-up of which they may be clinched, the hind-projections A² nearly parallel
to each other as represented, all substantially as shown and described.
Dated the 17th day of August 1892.
