Improvements in Safety-stirrups.
I, RUDOLF FIEK of No. 7 Scharrenstrasse, Charlottenburg, in the Kingdom of
Prussia, Empire of Germany, Manufacturer, do hereby declare the nature of my
said invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention consists in an improved safety stirrup designed to automatically
release the foot of a thrown rider.
Reference being made to the accompanying drawing Fig. 1 is a front elevation of
the improved stirrup closed. Fig. 2 is a side elevation thereof. Fig. 3 is a front
elevation of the stirrup in its opened position, on a smaller scale. Fig. 4 is a
horizontal section on line x x Fig. 1 and Fig. 5 is a similar section on line y y
Fig. 1.
The limb a² of the bow of the stirrup is in one piece and to the lower end of said
limb is hinged the foot-plate a³, the other end of which is hinged in like manner to
the lower end of the second limb a¹ of the bow. This limb a is in two detachable
pieces, the upper part is in one piece with the limb a² and the parts are connected
by a removable pin fpassing through holes in a tenon and mortise joint 6 and thus
holding the parts connected until its removal suffers the tenon to fall out of the
mortise and the limb a¹ to separate when the lower part of the limb a' and the foot-
plate a fall into the position shown in Fig. 3. The pin aforesaid is pivoted on the
respective end of the inner bow e the crown of which is lower than the crown of the
main bow of the stirrup to which the bow is hinged at d so that it may swing out-
ward as shown in dotted lines in Fig. 2 and in full lines in Fig. 3 and so release the
pin when the foot of the rider strikes it backward.
To prevent accidental movement of the bowe and consequent release of the riders'
foot when not required, the bow e is provided at the ends with the curved spring-
holders ee which are intended to clasp the limbs a¹ and a respectively and
hold the bow e until sufficient force is applied to the latter to release the said
holders.
The pin fis, in the example illustrated, fixed within the holder e¹ which latter in
this case also serves as a covering for the joint b.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
In a stirrup
1. The combination of the side limb a², the foot-plate a³ hinged at one end to said
side limb, the side limb a¹ in detachable parts the upper part connected to said
limb a², the lower part hinged to the other end of said foot-plate, the inner bow e
hinged to said stirrup, and the pin f on said bow e forming a removable fastener for
the detachable parts of the limb a¹ for the purpose set forth.
2. The combination of the side limb a², the foot-plate a³ hinged at one end to said
side limb, the side limb a' in two detachable parts, the upper part connected to said
limb a², the lower part hinged to the other end of said foot-plate, an inner bow e
hinged centrally to the crown of said stirrup, spring-holders el e on the ends of said
bow e adapted to respectively clasp the limbs a' and a², and the pin f on said bow
forming a removable fastener for the detachable parts of the limb a¹ for the purpose
set forth.
