I, LAZAR MLADEN SERBAN, of VIII, Scodagasse 6, Vienna, Austria, Gentleman,
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:
This invention relates to the construction and fixing of a detachable toe for a
horse shoe and to the formation of calks for horse shoes.
In the accompanying drawings similar letters of reference indicate the same
parts.
Figure 1 is a plan looking from below.
Figure 2 a vertical section of the front part of a horse-shoe with toe attached,
and Fig. 3 is a part plan of the shoe.
Figure 4 is an inside view and Figure 5 a section through the front part with a
countersunk notch for the fixing bolt.
Figure 6 is a perspective of the same.
Figure 7 is an inside view and
Figure 8 a section of a shouldered counter-sunk notch.
Figure 9 is a plan, Figure 10 an inside view and Figure 11 is a section of
another modification for square headed bolt.
Figure 12 illustrates the mode of fixing the toe when the horse shoe is on the
hoof.
Figures 13, 14 and 15 shew bolts with various forms of head.
Figure 16 is a perspective of a toe with laps in front and rear.
Figure 17 shews a toe with only a rear lap and
Figure 18 shews a toe with only a front lap.
Figure 19 is a perspective and Figure 20 is a longitudinal section of a toe with a
three-flapped lap on the front and rear.
Figure 21 is an elevation. Figure 22 is a plan.
Figure 23 is a perspective of a prismatic three-sided calk with plane surfaces.
Figure 24 is an elevation Figure 25 is a plan and
Figure 26 is a perspective of a taper three-sided calk with hollowed surfaces.
Figure 27 is the cross section of a calk of triangular section with two equal
flat sides.
.
Figure 28 is a section of calk with hollowed sides and
Figure 29 is a cross section of a three sided calk with india rubber inlaid.
The horse shoe a is widened at the front bend and has a notch b to receive a bolt d
the notch being shouldered or countersunk at 61 to receive the head d¹ of the
bolt d.
Figures 3 to 5 illustrate a horse shoe with a notch having inclined sides,
Figures 6 to 8 shew it with a shouldered notch and Figures 9 to 11 shew the slot
recessed for a square headed bolt.
The head of the bolt may have a flange das in Figures 13, 14 and 15.
The bolt d extends with its threaded part through a hole f¹ of a plate f² carry-
ing the too f and is fitted with a nut

page_text: The toe projects from a (Figures 16 to 19) plate 2 which is bolted against the
under side of the horse-shoe and has a lap or several laps h' in front and a lap h³
behind the shoe.
The laps h h may in the first place be directed outwards (Figure 20) to be bent
inwards after the toe f is bolted on the horse shoe.
For fixing the toe, the bolt d, as shewn in Figure 12, is introduced laterally into
the notch band then the toe plate is put on the bolt and fixed by screwing up
the nut J.
The laps h h hold the toe securely to the shoe, and relieve the bolt d from shock,
or strain.
In order to protect the nut 9 there may be on each side of it a rib k terminating
in a strengthening knob k¹.
The calks are of triangular section with three equal sides as shewn (Figures 21
to 26) or with two equal sides as in Figures 27 and 28 or all the sides may be
unequal, in each case with an end screw b.
The sides of the calk may be plane (as in Figures 21 to 23 and Figure 27) or
may be concave (as in Figures 24 to 26 and Figure 28) and the calks may be
prismatic, with parallel edges (as in Figures 21-23) or they may be pyramidal (as
in Figures 24-26) and may have india rubber inlaid as in Figure 29.
The calks may be of other forms; a triangular cross-section, as shewn in
Figures 20 to 28 is preferred.
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 detachable toc for a horse shoe secured by a bolt engaged in a notch of the
shoe, substantially as described with reference to Figures 1 to 20.inclusive.
2. Calks for horse shoes of triangular cross section substantially as described with
reference to Figures 21 to 29 inclusive.
