A Safety Stirrup Iron.
I, WILLIAM COOPER of No. 2 Mount Terrace York, in the County of Yorkshire,
Saddler do hereby declare the nature of this invention to be as follows:-
My invention relates to stirrups used in riding and has for its object the
production of a stirrup from which the foot will be easily detached if the rider fell
from the saddle. In order that my invention may be better understood I shall
hereafter refer to the annexed sheet of drawings whereon the same letters denote
like parts in the different figures.
Fig. 1. is a front view of the stirrup.
Fig. 2. shows in plan the part whereon the foot would rest.
Fig. 3. is a side view of Fig. 1.
Fig. 4. is a similar view to Fig. 1, showing the lower part of the stirrup detached
at one side.
By referring to the drawings it will be seen that the lower part c is hinged at b
and also furnished at this part with a pivot a which revolves in the side of the
stirrup. The other end of c is provided with a projection g which fits in a hole h
made in the lower end of the side d being held therein by the pressure of the
spring 8.
This side dis hinged at to the upper part of the stirrup so that it can move
outwards as shown in Fig. 4. The action of my improved stirrup is as follows:--
The foot of the rider in falling and thus dragging at the stirrup if caught therein
will press upon one side of the lower plate c which being provided with projecting
shoulders ff whose inner faces press obliquely upon each side of d. The plate c
revolving on its pivot a the shoulders ff by exerting a sliding pressure upon the
sides of d will force it outwards thus releasing the projecting part g from the hole h
whereupon the plate c being now unsupported at this side will fall downwards owing
to the action of the hinge b and as shown at Fig. 4 thus releasing the foot from the
stirrup. Fig. 5 shows at b a different way of hinging the plate c the hinge in this
case acting in a direction at right angles to that of the hinge shown at b.

I, WILLIAM COOPER of Railway Street, late of 2 Mount Terrace, York in the County
of York, Saddler, do hereby declare the nature of this invention and in what
manner the same is to be performed, to, be particularly described and ascertained in
and by the following statement :-
My invention tolator to Stimmung wadd in midine
binst them

page_text: of a safety stirrup from which the foot would be liberated if the rider should be
thrown from the saddle thus avoiding the accidents caused by the foot becoming
jammed in the stirrup as is often the case with stirrups of the ordinary pattern.
To illustrate my invention I have annexed a drawing to this specification to which
I shall afterwards refer, whereon like letters denote like parts in the different figures.
Fig. 1 is a front view of the stirrup.
Fig. 2 shows in plan the part whereon the foot would rest.
Fig. 3 is a side view of Fig. 1.
Fig. 4 is a view of Fig. 1 showing the lower part of the stirrup detached at one
side and that side bent outwards. By referring to the drawings it will be seen that
the lower part c is hinged at b so as to fall downwards when the other end is liberated.
It is also furnished with a pivot at a fixed in the side of the stirrups on which it can
be twisted round in addition to the action of the hinge b. The other end of c
is provided with a projection g which fits in a hole h made in lower end of the
side d the hole h being longer vertically than horizontally, as shown in Fig. 3.
The end of g is bent round into a hook so that when the foot plate c is revolved a
quarter of a turn on its pivot a the hook can be passed through the hole hand
the plate c being turned back into position as in Fig. 1 the hooked end of g locks
the side plate and keeps it in position. The side d is made with a hinge at e so
as to open outwards when disengaged from the hook g. The action of my improved
stirrup is as follows. When the rider falls out of the saddle his foot if held in the
stirrup would press upon that edge of the plate c which would be nearest the instep.
The plate c owing to the action of the pivot a would under this pressure revolve
about a quarter turn in the direction of the arrow in Fig. 3 and this would liberate
the hook g from the side plate d which would be pushed outwards and the plate c
would also fall owing to the action of the hinge b and the stirrup would appear as in
Fig. 4 the foot of the rider being thus freed from the stirrup.
By referring to the drawing left with my Provisional Specification it will be
seen that the plate c may also be furnished with projecting parts f which press
upon the sides of the plate d when c is revolved on its pivot, and thus help to
force the part g out of the hole h. Also instead of a hook g I may make this
part thickened at its end but only in a horizontal direction, the upper and lower
sides of g being smooth so that it will come out of the hole h when revolved a
quarter turn on the pivot a.
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.
(1) An improved safety stirrup having a foot plate c pivoted and hinged at one
end, the other end being held in a hinged side plate d, so as to be readily
detached therefrom when the plate c revolves under the pressure of the foot
substantially as set forth and shown on the drawings.
(2) In a stirrup, the combination of a revolving foot plate c and projections
at for the purpose of forcing the part g out of the hole h.
