page_text: I, ALFRED HENCKE, Lieutenant of Wilsnacker Strasse, Berlin, Germany, do
hereby declare the nature of my invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
The present invention relates to horse shoes and cousists in employing a rubber
plate attached underneath the shoe said plate extending over the entire lower
surface of the hoof and having a downwardly extending rim all round. The shoe
may also be provided inside the rim with calkins having a number of points as
hereinafter more particularly described.
And in order to make the present invention more easily intelligible reference is
had to the accompanying drawings in which similar letters denote similar parts
throughout the several views:
Fig. 1 being a view of the horse shoe seen from underneath.
Fig. 2 a cross section through the shoe,
Fig. 3 a plan of the iron shoe to which the rubber shoe is attached,
Fig. 4 a similar section to Fig. 2 but showing the calkins in position inside the
rim, and
Figs. 54 to 5 plans, side elevations and perspective views respectively of various
modified forms of the calkins.
The
Referring to Figs. 1 and 2 a is the rubber plate which extends over the whole
under surface of the hoof and is provided underneath with a downwardly extending
rim a all round. An iron shoe b of the ordinary construction is attached to the
hoof in the usual manner and provided with holes having screw threads and
corresponding in position to a similar series of boles in the rubber plate.
latter is then attached to the iron shoe by means of screws c¹ passing through the
rubber plate from underneath and screwing into the holes 61 of the upper shoe,
which should be made as light as possible and may be much thinner than the shoes
generally employed. A washer d is inserted between the screw head c¹ and the
rubber plate a to prevent the head of the screw gradually working into the rubber
and allowing the same to get loose. Instead of screws c¹ calkins e of the various
forms shown at Figs. 5A 5B, 5°, and 5D may be employed to prevent the horse from
slipping in very cold weather, the points of the calkins should reach down to the
lower surface of the rim a' so that when the latter is compressed through the
weight of the horse, the said points will come into contact with the ground.
The principal aim in a shoe of this kind is to make the bearing surface of
the shoe as small as possible and in order to accomplish this the rim a is provided
enclosing a space from which the air will be partially pressed out at each step of
the horse thus retaining the foot of the said horse in position on the ground by
suction, and rendering walking or running more reliable than hitherto when the
ground is hard, slippery or smooth.
The layer of thin mud which collects on asphalt and makes the latter so
dangerous for horses in wet weather will in the present case serve to tighten the
joint between the rubber rim a' and the asphalt and instead of increasing the
danger, decrease the same.
On granite and on uneven and bad roads the rubber rim serves as a buffer and
protects the feet of the horse from concussion.
The advantages resulting from this construction are great economy in shoes, only
four iron shoes being required per annum instead of forty as hitherto, the protection
afforded to the hoof and foot of the horse owing to the fact that all concussions

page_text: are avoided, safe, easy and noiseless movement of the horse, prevention of the
horse from damaging itself with its hoofs as when iron shod, prevention of all
foreign and unhealthy substances from insinuating themselves into the soft parts
of the foot and causing disease. As the rubber plate is independent of the iron
shoe, the saine may be changed when worn out without necessitating a reshoeing of
the horse.
The arrangement of the calkins inside the rubber rim prevents the horse from
damaging itself with the same, when walking or running.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is performed I declare that what I
claim is
=
1. In combination with a horse shoe, the rubber plate a extending over the whole
under surface of the hoof and having a downwardly extending rim a' all round
substantially as described.
2. In combination with a horse shoe a rubber plate having rim a' as specified
and attached to the iron or other shoe of the horse by means of screws c¹ having
washers d in the manner and for the purpose substantially as described.
3. In combination with a horse shoe, a rubber plate a having downwardly
extending rim a' as specified and being attached to the said shoe by means of
calkins e having washers d and passing through the said plate and screwing into
the iron shoe in the manner and for the purpose substantially as described and
shown.
