FREDERICK VALENTINE NICHOLLS of 2 Jermyn Street, London in the County of
Middlesex Saddler. I do hereby declare the nature of this invention to be as follows:-
To Stirrups of spade side shape I make a joint or hinge on the broad part of inside
leg, and the foot or bottom plate of Stirrup forms an axle working in a hole in this leg
below the hinge, and in the outer leg is a slot into which the plate Axle, at this end
part round and part flat is fitted, the flat part resting on two small projections on the
leg, when in the event of a rider falling with a foot caught in the Stirrup, the pressure
on the edge of the foot plate causes the axle to revolve on the outer supports, and the
round part to drop out of the slot, when the foot plate hangs down by the hinge, and
the foot is released. The foot plate is kept in a horizontal position by a fixed stud on
each end of axle, outside of legs, and the elastic leg sides can be sprung into position
with sufficient tightness to hold the foot plate horizontally until pressure is applied to
the edge in the act of falling.
I claim in this Patent an original improvement in the Pin and slot, by placing the
support of the foot plate outside the leg of Stirrup, instead of in the slot, the latter
involving weakness, and making the Stirrup unserviceable; the improvement being an
effective arrangement for release of the foot on falling, and giving sufficient strength
in the leg of Stirrup to allow of the riders full weight without damage or opening
out the slot.

page_text: COMPLETE SPECIFICATION.
An Improvement in Safety Stirrups.
I FREDERICK VALENTINE NICHOLLS of 2 Jermyn Street, London, in the County
of Middlesex 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 :-
To stirrups of spade side shape I make a joint or hinge, in the broad part of inside leg,
and the foot or bottom plate of Stirrup forms an axle, working in a hole in this leg
below the hinge; and in the outer leg is a slot into which the plate axle, at this end
part round and part flat, is fitted, the Hat part resting on two small projections on the
leg, when in the event of a rider falling, with a foot caught in the Stirrup, the pressure
on the edge of the foot plate causes the axle to revolve on the outer supports, and the
round part to drop out of the slot, when the foot plate hangs down by the hinge, and
the foot is released. The foot plate is kept in a horizontal position by a fixed stud in
each end of the Axle, outside of legs, and the elastic leg sides of Stirrup can be sprung
into position with sufficient tightness to hold the foot plate horizontally until pressure
is applied to the edge, as in the act of falling.
The invention is represented on the accompanying drawings, in which some parts
are designated with similar reference letters.
Fig. 1. Shews Stirrup closed. With pin A slot B. Hinge C, and tread plate D.
Fig. 2. Shews an underside view of tread plate D. with pin A and slot. B.
Fig. 3. Shews Stirrup open, to release foot of the rider.
Fig. 4. Shews side view of hinge C.
Fig. 5. Shews inside view of curved slot B.
I claim in this Patent, an original improvement, in the pin and slot, by placing the
support of the foot plate outside the leg of Stirrup, instead of in the slot, the latter
involving weakness, and making the Stirrup unserviceable; the improvement being an
effective arrangement for release of the foot in falling, and giving sufficient strength
to bear the riders full weight without damage, or opening out the slot.
FRED. V. NICHOLLS.
