PROVISIONAL SPECIFICATION.
Improvements in Stirrups.
I, WILLIAM BOWDLER of Field Street Bloxwich in the County of Stafford
Lockmaker do hereby declare the nature of this invention to be as follows :-
:-
This invention relates to improvements in that class of stirrups known as safety
stirrups in which an inner bow carried by the foot plate is made to leave the
stirrup thereby freeing the leg of the rider if thrown.
Near the bottom of each leg of the stirrup I make a curved slot to form a
bearing, and near this slot on the outside of the leg a projection forming stop
and operating as hereinafter described. Upon each leg of the inner bow and
near the foot plate I form or attach circular projections or pins forming axles,
the outer end of each of which is provided with a head or flange having in it
a notch or recess corresponding with the shape of the aforesaid stops on the
outside of the stirrup legs.
The pins or axles on the inner bow being passed into the curved slots or
bearings on the stirrup legs are turned therein until the recess in the head of
each axle meets the aforesaid stop on the leg. The inner bow is then parallel
with the outer bow and the stirrup is in position for ordinary use.
Should the
rider. be thrown, his foot pulling against the inner bow will cause its axles to
turn in their bearings and the head of the recess on each flange of the axle
acting as a lever on the aforesaid stops will throw the inner bow out of its
bearings leaving it free to be carried away by the foot of the rider.
In order that the bow thus carried away may not be lost it may be secured
to the foot of the rider by elastic ankle straps attached to the padding of the
bow or as may be found most convenient.
I may so form the recess on the flange of each axle and the corresponding
stop on the stirrup leg as to allow the foot plate a little play forward.

COMPLETE SPECIFICATION.
Improvements in Stirrups.
I, WILLIAM BOWDLER, of Field Street, Bloxwich in the County of Stafford,
Lockmaker, 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 relates to improvements in that class of stirrups known as safety
stirrups in which an inner bow carried by the foot-plate is made to leave the
stirrup thereby freeing the foot of the rider if thrown.
Upon the accompanying sheet of drawings illustrating my invention,
Figure 1 represents a side elevation of a stirrup embodying my invention.
Figure 2 a front elevation of same.
Figure 3 is a side view but with inner bow partly turned.
Figure 4 is a similar view but representing the inner bow released.
It will be seen from the drawings that at or near the bottom of each leg A
of the stirrup I make a curved slot B to form a bearing, and near this slot
on the outside of the leg a projection forming stop C, and operating as
CD027

page_text: hereinafter described. Upon each leg of the inner bow D and near the footplate E
I form or attach circular projections or pins forming axles F the outer end of
each of which is provided with a head or flange G having in it a notch or
recess H corresponding with the shape of the aforesaid stops C on the outside
of the stirrup legs A.
The pins or axles F on the inner bow D being passed into the curved slots
or bearings B on the stirrup legs A are turned therein until the recess H in
the head G of each axle meets the aforesaid stop C on the leg.
The inner bow D is then parallel with the outer bow and the stirrup is in
position for ordinary use. Should the rider be thrown his foot pulling against
the inner bow will cause its axles to turn in their bearings, and the head of the
recess on each flange G of the axle acting as a lever on the aforesaid stops C,
will throw the inner bow D out of its bearings leaving it free to be carried away
by the foot of the rider.
In order that the bow thus carried away may not be lost, it may be secured
to the foot of the rider by elastic ankle straps attached to the padding of the
bow, or as may be found most convenient.
I may so form the recess on the flange of each axle and the corresponding
stop on the stirrup leg as to allow the foot-plate a little play forward.
Having now particularly described and ascertained the nature of iny said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In safety stirrups having a detachable inner bow D, the combination of the
curved slots B with the stop-piece C, and notched or recessed head G, substan-
tially as described and for the purpose specified.
