I, OTTO ANTON DIECKMANN, Gentleman, residing at No. 2810 Caroline
Street, in the City of St. Louis, State of Missouri, United States of America, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
My invention relates to an improved horse shoe, and consists in the novel
arrangement and combination of parts, hereinafter specified and claimed.
The object of my invention is to construct a horse shoe with removable toe and
heel-calks, the same possessing superior advantages in point of simplicity,
durability and general efficiency.
In the drawings:
Figure 1 is a view in perspective of a horse shoe constructed in accordance with
my invention.
Fig. 2 is a detail view of a portion of a horse shoe, the same having a calk in
position thereon, a portion of the horse shoe being broken away to more clearly
illustrate the device.
Fig. 3 is a view in perspective of one of the removable heel-calks.
Fig. 4 is a view in perspective of the removable toe-calk as contemplated by my
invention.
Fig. 5 is a sectional view taken approximately on the indicated line 5-5 of
Fig. 1.
1 indicates a horse shoe of the ordinary form and construction, the same being
provided in each of the heel points with screw-threaded apertures 2. A similar
screw-threaded aperture 3 is located at that point of the horse shoe where the toe-
calk is usually located.
The heel-calk 4 is V-shaped in cross-section and constructed with a screw-
threaded lug 5 that is adapted to enter the screw-threaded bores or apertures 2.
Formed integral with and extending at right angles to the base of the calk 4 is a
spring-arm 6, the same being provided at its end with lateral projections 7.
In the end of the spring-arm 6 between the lateral projections 7 is formed a
notch or depression 8, the purpose of which will be presently shown.
The toe-calk 9 is V-shaped in cross-section and provided on one side with the
integral laterally projecting spring-arms 10 formed integral with the under side of
the calk 9, and projecting therefrom is a screw-threaded lug 11 that is adapted to
enter the screw-threaded aperture 3 located in the toe of the shoe 1.
In positioning the heel-calks upon the rear ends of the shoe 1, the screw-
threaded lugs 5 are positioned in the screw-threaded apertures 2 and the calk so
manipulated as that the faces of said calk and the spring-arm 6 engage with the
face of the shoe. When the calk is in this position and the spring-arm 6 lies along
the face of the shoe 1, the laterally projecting portions 7 that extend beyond the
edges of the heel-ends of the shoe are upset or bent at right angles to the spring-
arm 6, as clearly illustrated by solid lines in Fig. 1, and by dotted lines in Fig. 3.
This manner of locating the calk upon the shoe serves to rigidly fix said calk and
to efficiently prevent the same from being turned while the shoe is in use upon the
animal's hoof.
When it is desired to remove either one of the heel-calks for the purpose of
sharpening, straightening or lengthening the same, a pointed tool of any kind is

page_text: raised or pried upwardly until the ends 7 are free to pass over the face of the heel-
point of the shoe. By now unscrewing the calk 4 the same may be quickly removed
from the shoe.
Another manner of removing the heel-calks is to straighten or flatten out the
laterally projecting portions 7 by, means of, a hammer or like tool, which will allow
the calk to be removed without necessitating the prying up or raising of the spring-
arm 6 from the heel-point of the shoe.
The toe-calk is positioned upon the toe of the shoe by locating the screw-threaded
lug 11 in the screw-threaded aperture 3 and manipulating said toe-calk until it
engages against the under face of the toe of the shoe. The ends of the lateral
projections 10 are now. bent at right angles to the body portions of said projections
until they engage with the inner edges of the shoe, thus rigidly fixing said calk
and preventing the same from turning, unscrewing and losing when the shoe is in
position upon the hoof of the animal.
When it is desired to remove this toe-calk, the bent ends of the laterally
projecting portions 10 are bent into a plane with the bodies of said laterally
projecting portions which will allow the calk 9 to be unscrewed and removed from
the shoe.
Thus it will be seen how I have constructed a horse shoe with removable calks,
the same being quickly and efficiently fixed to the shoe, and which may be when
desired, expeditiously and easily removed. A horse shoe so constructed is
inexpensive, efficient and of longer life than is a shoe of the ordinary
construction.

"
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, 1 declare that what
I claim is:
1. The improved horse shoe, constructed.. with screw-threaded apertures 2 in its
heels extending at a right angle to the face of the shoe, and heel-calks 4 having each
a single integral screw-threaded lug 5 engaging in said screw-threaded apertures,
whereby said calks may be secured in position by revoluble movement in one.
direction and detached by a reverse revoluble movement, substantially as herein
specified.
2. A horse shoe constructed with removable heel and toe-calks, said calks being
provided with integral screw-threaded lugs adapted to enter screw-threaded
apertures in the shoe, said calks being also constructed with integral spring-arms,
the ends of which are adapted to be bent at right angles to the body portions
thereof to engage the edges of the shoe.
3. The combination of a horse shoe constructed with screw-threaded apertures
in its heel-ends, and calks provided with, screw-threaded lugs adapted to enter said
screw-threaded apertures, and provided also with spring-arms the laterally
projecting ends of which are adapted to, be bent so as to engage the edges of the
shoe and prevent the calks from turning.
4. The improved horse shoe, constructed with screw-threaded apertures 2 in its
heeis extending at a right angle to the face of the shoe, heel-calks 4 having screw-
threaded lugs 5 engaging in said apertures, said shoe, having also a screw-threaded
aperture 3 extending at a right angle to the face of the shoe and located where
the toe-calk is affixed, and a toe-calk 9 having a screw-threaded lug 11 engaging
in, said screw-threaded aperture 3, whereby all of said calks may be secured in
position by revoluble movement in one direction and detached by a reverse
movement, substantially, as herein specified.
