IN HORSE-SHOES."
"IMPROVEMENTS
These improvements in horse-shoes have for object to easily and quickly remove
or renew the toe pieces, caulks, and other wearing parts of the shoe without
requiring a removal of the main shoe from the hoof of the animal.
The main shoe, the top surface of which must be carefully fitted to the hoof of
the animal, consists of a flat iron shoe piece of common construction, which may be
fastened to the hoof by nails or otherwise, and which may be furnished with clips
or tongues in front and at the sides of the shoe. In the bottom plane of this shoe
are constructed three parallel dovetail shaped grooves, of which one is placed at the
front end of the other two, one at each hinder end of the shoe. These grooves are
prepared for the reception of toe piece and caulks, which are furnished with corre-
sponding dovetail projections and are slipped into the grooves sideways, and are kept
in position by flat springs fastened to the top or main shoe, which springs catch into
corresponding flat recesses of the toe piece and caulks as soon as these parts have
arrived in proper position. The toes and caulks of these shoes may be furnished
with sharp or flat working surface as desired; the same may also be constructed
hollow, and be packed from the open bottom end with hemp or other suitable
material; or those applied during the stay of the animal in the stable may be
furnished with flat end plates, which prevent the animal from hurting himself by
the edges of the sharp toes and caulks or parts of the shoe.
Instead of toes and caulks, as before described, a complete bottom shoe running
all round the bottom of the top shoe may be attached to the latter; the bottom
shoe is in that case furnished with corresponding dovetail projections to fit the
grooves of the upper shoe. The bottom shoe may be solid or be of a hollow casing
form, as desired, and in the latter case it may be furnished with an elastic
packing.
Instead of bottom shoes of the construction before described, plates of flat iron,
covered with leather, felt, or other material at the bottom side, may be employed,
which plates are at the top again furnished with projections to fit the dovetail
grooves of the main shoe, into which the former are brought or slipped in from the
side, and kept in position in the same manner as before described.

OTTO LAMPE, Engineer, of the City of Hamburg, Germany. IMPROVEMENTS
IN HORSE SHOES."
These improvements in horseshoes have for object to easily and quickly remove
or renew the toe-pieces, caulks, and other wearing parts of the shoe without
requiring a removal of the main shoe from the hoof of the animal.
The main shoe, the top surface of which must be carefully fitted to the hoof of the
animal, is shown in Figs. 1 and 2, and consists of a flat iron shoe piece A of
common construction, which may be fastened to the hoof by nails or otherwise, and
which may be furnished with clips or tongues B in front and at the sides of the
shoe. In the bottom plane of this shoo are constructed three parallel dovetail
shaped grooves a, b, c, of which one is placed at the front and of the other two, one
at each hinder end of the shoe. These grooves are prepared for the reception of toe
piece and caulks, which are furnished with corresponding dovetail projections, and
are slipped into the grooves sideways (Figs. 3 and 4), and are kept in position by
flat springs m, m³, m³, fastened to the top or main shoe, which springs catch into
corresponding flat recesses of the toe piece and caulks as soon as these parts have
arrived in proper position. The toes and caulks of these shoes may be furnished
with sharp or flat working surface, as desired; the same may also be constructed
hollow, and be packed from the open bottom end with hemp or other suitable
material (Figs. 5, 6, and 7); or those applied during the stay of the animal in the
stable may be furnished with flat end plates (Figs. 8, 9, and 10), which prevent
the animal from hurting himself by the edges of the sharp toes and caulks or parts
of the shoe.
Instead of toes and caulks, as before described, a complete bottom shoe D running
all round the bottom of the top shoe A may be attached to the latter; the bottom
shoe is in that case furnished with corresponding dovetail projections to fit the
grooves of the upper shoe. The bottom shoe may be solid or be of a hollow casing
form, as desired, and in the latter case it may be furnished with an elastic
packing H (Fig. 11).
Instead of bottom shoes of the construction before described, plates of flat iron,
covered with leather, felt, or other material at the bottom side, may be employed,
which plates are at the top again furnished with projections to fit the dovetail
grooves of the main shoe, into which the former are brought or slipped in from the
side and kept in position in the same manner as before described.
Having now described the nature and particulars of my said Invention I claim,-
The construction of a plain main or top-shoe, furnished at its bottom side with
parallel running dovetail shaped grooves and flat springs, which grooves are
prepared for the reception and attachment of either a wearing shoe, or of toes
and caulks of any convenient construction, for the purpose and in the manner
as described, and as illustrated by the Figures of the accompanying Sheet of
Drawings.
In witness whereof, I, the said Otto Lampe, have hereunto set my hand
and seal, this Twenty fourth day of November, in the year of our Lord
One thousand eight hundred and eighty.
