Improvements in Horse Shoe Calks.
I, FRANZ OSCAR KUNZE, of Klotzsche, near Dresden, Saxony, Smith, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:-
-
This invention relates to a horse shoe calk the form and arrangement of which,
with two studs, necessitates only a slight weakening of the shoe whilst permitting
its movement in any desirable direction without undue displacement of the stud
holes and further, when the horse turns round on the roadway, without such an
action upon the studs as would cause any enlargement of the stud holes.
In the accompanying drawing Figs. 1 to 4 are respectively a plan view, a side
view, and end views of one construction of the calk of the invention, and Figs. 5
to 14 similar views of another construction, Figs. 5 and 9 shewing the same applied
to a horse shoe.
a are two studs provided one at each end of the calk and of any suitable form,
as round. elliptic, or prismatic, but preferably round as shewn as being easiest to
make. They are made somewhat taper to facilitate insertion into corresponding
holes in the shoe and a tight fit therein. They may be provided either in the
middle of the calk body b as seen in end view (Fig. 4) or to one side (Fig. 3)
which latter construction gives a better result when the front edge of the calk
engages in the ground.
With a view to preventing the loss of such of these calks as may be carelessly
placed in position or becomes loose through inattention, they may, as shewn in
Figs. 5 to 14 he provided with a lug c for attachment by means of a screw & to
a shoe e. The lug c is preferably located as shewn and the screw hole a recessed
or countersunk to allow the screw head to come flush or slightly below the surface
of the lug, down to which the calk might wear without losing it. In order to per-
fectly attain this object the lug c may be made to stand out somewhat upwards
towards the shoe and a recess f provided in the latter for the reception of the
upturned lug so that when the calk hody b comes to bear against the shoe the lug
will rest in said recess, and when the calk is worn out the screw head will be either
not worn at all or only slightly worn. In this case also the studs a may be located
either in the middle of the calk body as seen in end view (Figs. 8 and 14) or to
one side (Figs. 9. 12, and 15) and the tread of the calk may be either blunt (Fig. 2)
or sharp (Fig. 9).
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I claim
is:
1. A horse shoe calk having two studs for fitting into only two holes in the shoe
whereby the shoe is not much weakened, its movement permitted in any convenient
discation without distortion of the stud holes, and in turning round on the roadway.

page_text: without such an action upon the studs as will cause an enlargement of the holes and
a loosening of the calk, substantially as described and shewn.
2. In the horse shoe calk referred to, the arrangement of a perforated lug c and
screw d for securing the calk to the shoe, substantially as described and shewn.
3. In the horse shoe calk referred to, the arrangement of the lug c bent upwardly
towards the shoe and adapted, when the calk is very much worn to take into a
recess in the shoe, whereby the screw which secures the calk to the shoe is pro-
tected from injury, substantially as described and shewn.
