PROVISIONAL SPECIFICATION.
An Improvement in Safety Riding Stirrups.
1, JOHN BRADBURY of Regent Bit Works, Green Lane Walsall in the County of
Stafford, Manufacturer of riding and driving bits do hereby declare the nature of this
invention to be as follows:-
This invention relates to Ladies Safety riding-stirrups which has a padded inner
bow turning upon centre-pins in the sides of an outer bow and having a falling tread
or foot-plate.
One end of this plate is jointed in the ordinary way to the bottom of one side of
the outer bow, whilst on the other end 1 form a vertical hook which corresponds with
and fits into a slot in the other side of the outer bow, which is secured against lateral
pressure by the said hook having a projecting head similar to the head of a round
headed screw.
The padded inner bow has two sidos_extending nearly to a level with the tread or
foot-plate and in one of these sides I form a semicircular recess, and when this
vertical hook is in the outer bow and the padded inner bow moved to a corresponding
vertical position with the outer one, the seinicircular recess grasps the under side of
the vertical hook and secures it against downward pressure.
This stirrup releases the foot of the rider in the usual way when thrown.

COMPLETE SPECIFICATION.
An Improvement in Safety Riding Stirrups.
I, JOHN BRADBURY, of Regent Bit Works, Green Lane, Walsall, in the County of
Stafford, Manufacturer of Riding and Driving Bits, 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 :-
This invention has reference to that class of safety riding stirrups which have a
padded inner bow turning upon centre pins in the sides of an outer bow and have a
falling tread or foot-plate and the said invention consists in the herein described
improvements in the construction of such stirrups whereby the foot-plate is prevented
from becoming accidentally unlocked when the rider is passing through fences or at
other times.
My invention is illustrated by the accompanying drawing on which Fig. 1 represents
a lady's safety stirrup closed constructed according to this invention; Fig. 2 shows
part of the same in cross section; Fig. 3 is a general view of the same open and
Figs. 4, 5 and 6 represent the tread or foot-plate of the same separately.
The same letters of reference indicate the same parts in all the Figures of the
drawing.
a a are the two legs of the outer bow and 6 is the tread or foot-plate jointed to
the leg a in the usual manner. c is the inner bow turning on the centro pins d' d' in
bearings in the legs a¹ a². At the outer end of the tread & I form the vertical hook e
which fits into a corresponding slot in the bottom of the leg a¹ and the leg a' is
secured against lateral pressure by the hook e having a projecting head g against the
sides of which the leg a bears when the stirrup is closed. In that side of the inner
bow c which corresponds with the leg a¹ I forni a recess the lower side of which
is the arc of a circle of which the joint pin d' is the centre. This recess is so situated
that when the stirrup is closed as shewn in Figs. 1 and 2 and the vertical hook e is in

page_text: position in the slot f and the inner bow c is moved to its vertical position the under-
side of the recess grasps the underside of the vertical hook e and secures the
tread against downward pressure.
When the rider is thrown her foot turns the top of the inner bow outwardly in
the usual way as shown in Fig. 3 which withdraws the recess from the book e and
the tread being then unsupported turns down on its jointed end as shewn in Fig. 3
thus releasing the rider's foot from the stirrup.
As, when the stirrup above described is closed, (see Figs. 1 and 2) no part of the
inner bow projects in any way beyond the outer bow or below the tread, it is
impossible for anything with which the outside of the stirrup may come into contact
to turn the inner bow on its joint pins to release the tread, thus preventing the
stirrup becoming accidentally opened when the rider is passing through fences.
I wish it to be understood that I do not make any general claim to a safety
stirrup in which the tread is hinged to one of the side legs of the outer bow and its
free end detachably connected to the other leg and released by an extension of an
inner bow between the legs of the outer bow, as I am aware that stirrups constructed
and operating in this manner have been used before my invention; but,
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 safety riding stirrup of the kind herein referred to, the employment of an
upwardly projecting hook e, at the outer or free end of the tread, which when the
stirrup is closed engages with the slot ƒ in one of the stirrup legs and with a rocess /
in the inner bow above tho tread so as to be released when the inner bow c is
turned for the purpose and substantially as herein before described and illustrated by
the accompanying drawing.
Dated this 18th day of October 1889.
JOHN BRADBURY.
