page_text: LETTERS PATENT to Friedrich Hermann Felix Engel, Civil Engineer and
Patent Agent in the city of Hamburg Germany for an Invention of
IMPROVEMENTS IN HORSE-SHOES A communication to him by Otto Lampe
of Hamburg in the German Empire.
PROVISIONAL SPECIFICATION left by the said Friedrich Hermann Felix
Engel at the Office of the Commissioners of Patents on the 31st July 1882.
FRIEDRICH HERMANN FELIX ENGEL Civil Engineer and Patent Agent in the
city of Hamburg Germany "IMPROVEMENTS IN HORSE-SHOES a communication
to me by Otto Lampe of Hamburg in the German Empire
"
This invention relates to certain improvements in Horse-shoes and relates to
improvements in the means of attaching toes and calks as well as secondary iron
shoes to the shoe fastened to the hoof of the animal.
The main-shoe that is by means of nails in a manner commonly used now with
horse shoes fastened to the hoof, has at its bottom side three dovetail shaped
parallel running grooves of which one is placed near the front the other two at
the ends of the shoe. To the upper side of the secondary shoe or of the toes and
calks are formed projections corresponding in size and shape to the grooves of the
main-shoe and these parts can from the side be slipped into the grooves and can
afterwards by means of steel keys passed through top shoe and bottom shoe or
through the toes and calks if the latter are used be kept in position. The keys
are each furnished with a nose and can be drawn out by means of a lever or other
suitable instrument for the purpose of exchanging the above named parts.

City of Hamburg Germany "IMPROVEMENTS IN HORSE SHOES " a communication

This Invention relates to certain improvements in horse shoes and relates to
improvements in the means of attaching toes and calks as well as secondary iron
shoes to the shoe fastened to the hoof of the animal.
The main shoe that is by means of nails in a manner commonly used now with
horse shoes fastened to the hoof, has at its bottom side three dovetail shaped
parallel running grooves of which one is placed near the front, the other two ab
the ends of the shoe. To the upper side of the secondary shoe or of the toes and
calks are formed projections corresponding in size and shape to the grooves of the
main-shoe and these parts can from the side be slipped into the grooves and can
afterwards by means of steel keys passed through top shoe and bottom shoe or
through the toes and calks, if the latter are used, be kept in position. The keys
are each furnished with a nose and can be drawn out by means of a lever or other
suitable instrument for the purpose of exchanging the above named parts.
In the accompanying sheet of drawings Figs. 1 and 2 show the construction of
the top or main shoe; Fig. 1. being a side elevation and Fig. 2 ground plan seen
from below; Fig. 3 represents in section a main shoe in combination with a
secondary shoe Figs. 4 and 5 are respectively ground plan and side view of a
main shoe in combination with toe and calks.
The main shoe A is furnished with parallel running dovetail grooves a, b and c
into which corresponding projections e of the secondary shoe D (Fig. 3) can be
fitted for the purpose of combining the two shoes.
Or toes and calks S (Fig. 5) furnished with similar projections e can be attached
to the main shoe A.
To keep the secondary shoe or toes and calks in position keys m, m' m² are
employed. These keys are of rectangular section and are driven in into grooves i
partly formed to the main shoe A and partly to projections c.
The secondary shoe or toes and calks before described may be exchanged
without removing the main shoe from the hoof of the animal. The keys mare
removed and the other parts are then by means of a hammer or other tool, pushed
sideways out of the dovetail recesses of shoe A.
The secondary shoe as well, as toes and calks can be of very different con-
struction; Fig 3 represents for example a secondary shoe furnished with an elastic
packing H
Having now described the nature and particulars of the said Invention I
claim
The combination of a secondary shoe or of toes and calks applied to the main
horse shoes A by means of dove tail projections e corresponding to the grooves of
the main shoe which parts are kept in position by keys m as and for the purpose
herein set forth and as shown and described in reference to the accompanying
sheet of drawings.
In Witness whereof I the said Friedrich Hermann Felix Engel have hereunto
set my hand and seal this twenty seventh day of January in the year of
our Lord one thousand eight hundred and eighty three.
