Improvements in and connected with Stirrups.
J, FRIEDRICH WILHELM MROSE, residing at Coesfeld, Kingdom of Prussia,
Empire of Germany, Treasurer do hereby declare the nature of this invention and
n 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 a stirrup for the purpose of preventing the foot
catching in the iron when being knocked off from the horse or when the latter
tumbles, or when mounting and dismounting the horse.
Fig. 1 of the accompanying drawing shows the closed stirrup,
Fig. 2 shows the one side wall with the small segment ²,
Fig. 3 shows the stirrup quite open.
The axle b, after being pushed through the end walls of the tread plate
for which purpose the said and walls are in their centre provided with circular
holes, is jointed to the shank of the iron az by means of a pin a. The other end
of the axle b has a square head which prevents the tread plate slipping down,
forming a loop, and loosely pushed on the other shank end of the iron a.
At the same end the tread plate e possesses, above the hole which forms the
bearing of the axle, a segment which partly projects over the loop and, when the
tread plate is turned into its position of repose, catches into a notch a of the
iron a,
thus holding the tread e in its closed position. In this way the tread
plate c is held at the one side of the iron by the axle b while at the other side the
axle bis carried by the tread plate cor by its segment c².
The springs d d-fixed at the lower surface of the tread plate c, at both sides
of the axle b, which are exercising a uniform pressure upon the tongue d¹licing
in a flat notch of the axle b, are causing the tread plate e to stand in its position
of repose.
For protection of the axle and the spring d d, the lower surface of the tread
plate can be covered by a light plate. When the foot catches in the stirrup a
natural pressure is caused upon the side of the plate e next to the rider, while
the other side is released. This pressure, being considerably stronger than the
resistance of the spring d d, causes the tread plate e to turn on the axle which
itself does not revolve, whereby the segment of the tread plate is disengaged
out of the natch a² of the iron a, so that the axle b with the tread plate must
swing round and the foot is released. In ordinary riding, even if the foot slips
through the stirrup as far as the heel of the boot, the tread cannot disengage
because the turning of the tread plate which would be necessary for it cannot take
place.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:
In a safety stirrup, which opens with the turning of the tread plate, the
axle (6), which does not revolve itself of the turmable tread wlate (d)
at ang side

page_text: jointed to the iron, but at the other pushed loosely on the stirrup end, and held
on the latter side in closed position by a segment (2) at the tread plate, which
catches into a notch (a²) of the iron, for the purpose of disengaging the segment (2)
from the iron by the turning taking place when the foot is caught in the stirrup,
so that the axle (6) can turn round with the tread plate downwards, and open the 5
stirrup, substantially as described.
