I HERMANN LÜDECKE of 101, Königgrätzer strasse, first floor in the City of Berlin,
Kingdom of Prussia, German Empire, Gentleman, do hereby declare the nature of
my Invention for IMPROVEMENTS IN HORSE SHOES AND IN MOULDS FOR MANUFACTURING
THE SAME 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 with india-rubber sheathing and
moulds for manufacturing the same; the object of mthe same from slipping on smooth
said invention being to produce
a.horse-shoe which will prevent the animal wearing
pavement, will protect the animal's hoof from injury by the hard granite or other
pavement and which possesses the great advantages of extreme lightness and great.
durability.
In order to increase the durability of my improved horse-shoe, I apply serpentine
ribs to the metallic core, which said ribs tend to prevent the undue wear and tear of
the india-rubber sheathing and to bind the said sheathing firmer to the metallic core:
One very great disadvantage of the horse-shoe clad with india-rubber known up to
the present day and which has debarred their general use for carriage, riding and other
horses, is that the said india-rubber sheathing is very liable to crumble away and the
necessary hold on the iron core is too slight.
"
By applying my serpentine ribs to the lower surface of the metallic core and
around the nail-holes, the india-rubber receives a hitherto never attained hold. and
is protected from crumbling and all undue wear and tear.
The said serpentine ribs present a comparatively large frictional surface, strengthen
the shoe and prevent the nails being driven so deep or so inclined that the hoof of
the animal is injured. The india-rubber sheathing when semi-fluid during manu-
facture, penetrates into four or more or less holes or openings in the iron core and
increases the adhesion of the sheathing to the iron. The rear holes or openings can
be provided with screw threads or can be made of conical form for receiving suitable
caulks. In order to prevent the semi-fluid mass from entering the nail-holes,
small pegs can be arranged in the moulds.
The mould which is destined to receive the prepared chilled cast, wrought iron

page_text: or other suitable core, consists of five or more parts suitably hinged together, i.e.,
the base, two laterally hinged curved arms, rear ledge and superior part or cover; the
latter being provided with small projections corresponding with the nail-holes in
the iron or other core, so as to prevent the india-rubber, during subsequent vulcanizing,
from penetrating and closing up the said nail-holes.

a, Fig. 1, is the horse-shoe; b, 61, the serpentine ribs; c, the holes in which the
nails are to be driven; d, d', d and d³ are the above-mentioned holes for the semi-
liquid india-rubber to enter and subsequently set; e, is the toe-piece of the shoe
against which the said serpentine ribs abutt; e¹, the upward projecting part of the
core, Figs. 1, 2, 4 and 5; Figs. 7 & 8 represent caulks, which in case of necessity
can be screwed into the holes which are threaded for the purpose or, which, said
holes, can be conically-formed so as to receive the aforesaid conically-shaped caulks.
The mould consists of five sections which are attached to each other by hinges.
The part B, receives the horse-shoe which is to be sheathed and which is laid in the
cavity k. The toe-piece of the shoe rests in the recess ¹, behind the hinge of the
lower portion B. The side-walls are formed by two curved arms h, h¹, which are
hinged together at the forward end and have their fulcrum so arranged as to allow
them to turn around the pivot i and subsequently be opened to allow the horse-shoe
to be removed, as shown in Fig. 9.
The movable part is connected with the lower part B, by means of the hinges m, m³.
The cover A, is connected with the rear part of the mould, by means of the hinge n.
The said cover A, contains the mould for the surface p, and the pegs q, which
close through the orifices where the nails are to be driven and prevent the viscid
india-rubber mass from entering into the said holes. The surface p on the cover A,
is covered with small ridges which cross each other at angles of varying acuteness.
These ridges give the horse-shoe a firm hold on smooth pavement. 0, 0¹, 03, 00
and, of are small projections which fit in the corresponding recesses o³, o*, o' and 08
of the rear ledge and the curved arms h, h¹, of the mould. In order to cover the
horse-shoe with the india-rubber sheathing, I prepare strips of india-rubber, wind
them around the core and then place the so-prepared core in the mould. Here-
upon the cover A of the mold B, is closed and pressed on the lower part or base
of the same, by means of the bow r and the eccentric t. After being thus prepared the
mould is placed in an oven or stove so as to melt the india-rubber and cause it to
adhere most thoroughly to all parts of the iron, which is done in a very short time,
upon which the mould is removed from the said oven or stove. After this the
bow is removed, the lid A, thrown back the rear-ledge / freed from the lower
part B, and the two curved arms h h¹ opened, so as to allow the covered horse-shoe
to lay in an exposed position on the lower part B. The bow r has an arm r¹, which can
turn on the fulcrum s, which said arm, can be thrown open when adjusted to the
form or mould. An eccentric t, is arranged in the upper part of the mould with its
fulcrum at u, for the purpose of pressing the two halves of the mould together.
Instead of employing serpentine ribs as shown in the accompanying drawings and
described in the foregoing specifications, two or more curved ribs can be employed,
without departing from the nature of my invention.

page_text: 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. An improved horse-shoe, characterized by a core of metal provided with serpen-
tine ribs and a sheathing of india-rubber, substantially as shown and described.
2. An improved horse-shoe, consisting of a sheathing of india-rubber and a metallic
core with raised ribs on the lower, wearing surface, substantially as shown and
described.
3. A mould for forming the india-rubber sheathing around the metallic core, con-
sisting of the recessed base B, the laterally movable arms h, h¹, rear ledge 1,
hinges i, m, m', n and cover A, substantially as shown and described.
4. The combination of the recessed base B, the cover A, ledge p, projections
lugs o, o, substantially as shown and described.
and
5. The general arrangement construction and employment of my improved mould
