I, FRANCIS HENRY WINCER, of 72, Bath Street and Vicarage Street, Walsall,
Staffordshire, Stirrup Manufacturer, do hereby declare the nature of this invention to
be as follows :-
This invention consists of the improvements in stirrups hereinafter described the
object being to arrange for one or both of the legs or sides of a stirrup to be readily
detachable from the tread or bottom part on a rider being thrown so as to release his
foot and prevent his being dragged.
In one form of my invention one of the legs of the stirrup and preferably that leg
with which the upper part of the bow is formed is hinged to the tread or bottom part
of the stirrup in the well known manner and to the upper part of this leg the second
or detachable leg is hinged or jointed preferably by an ear on the upper part of one
leg fitting between a pair of corresponding ears on the other leg, a joint pin passing
through the ears and securing the two legs together. I prefer to square off the ears
on each leg to abut against corresponding parts on the other leg so as to maintain the
proper shape of the bow and give to the joint a neat appearance. The lower part of
the detachable leg is so connected to the tread that under ordinary circumstances it has
no tendency to become detached therefrom but on the leg being subjected to a side
pressure as would be the case on a rider being thrown its lower end becomes detached
from the tread and this leg and the tread are then free to turn on their joints and open
out from one another to free the rider's foot, the stirrup meanwhile hanging from the
stirrup leather and no part becoming wholly detached or liable to be lost.
In order that the lower end of the detachable leg may under ordinary circum-
stances be securely connected to the tread and yet, when subjected to an outward
pressure as above described, be free and become detached, it and the tread are
preferably constructed as follows:-The lower part of the detachable leg fits in a
vertical slot in the tread so as to prevent the end of the leg moving sideways and in
each side of this slot is a horizontal slot in which two lateral projections formed on
the bottom of the leg fit, which projections secure the tread from moving downwards

page_text: until the said lower end of the leg is detached therefrom. Projecting from the inner
side of the said lower part of the detachable leg is a pin, which, when the stirrup is
closed, takes into a corresponding hole in the tread. This pin is split or divided for a
short distance from its outer end or is otherwise formed so as to spring into the said
hole and engaging with it prevent the leg becoming detached from the tread until the
former is subjected to a certain outward pressure as above described.
I sometimes make both legs detachable from the tread similarly as above described
with reference to one leg, the stirrup will then open at either side and the tread be
secured to that leg which does not happen to become detached, or the tread may become
detached from both legs.
I sometimes joint or hinge one or both of the legs to the tread and make the stirrup
to open at the upper part of the bow in the ordinary manner in combination
with a detachable connection as above described of one or both of the legs to the
tread.

page_text: improvements in Surrups.
I, FRANCIS HENRY WINCER, of 72, Bath Street and Vicarage Street, Walsall,
Staffordshire, Stirrup Manufacturer, 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 consists of the improvements in stirrups hereinafter described the
object being to arrange for one or both of the legs or sides of a stirrup to be readily
detachable from the tread or bottom part on a ride being thrown so as to release his
foot and prevent bis being dragged.
In one form of my invention one of the legs of the stirrup and preferably that leg
with which the upper part of the bow is formed is hinged to the tread or bottom part
of the stirrup in the well known manner and to the upper part of this leg the second
or detachable leg is hinged or jointed preferably by an ear on the upper part of one
leg fitting between a pair of corresponding ears on the other leg, a joint pin passing
through the ears and securing the two legs together. I prefer to square off the ears
on each leg to abut against corresponding parts on the other leg so as to maintain the
proper shape of the bow and give to the joint a neat appearance. The lower part of
the detachable leg is so connected to the tread that under ordinary circumstances it has
no tendency to become detached therefrom but on the leg being subjected to a side
pressure as would be the case on a rider being thrown its lower end becomes detached
from the tread and this leg and the tread are then free to turn on their joints
and open out from one another to free the rider's foot, the stirrup meanwhile
hanging from the stirrup leather and no part becoming wholly detached or liable to
be lost.
In order that the lower end of the detachable leg may under ordinary circumstances
be securely connected to the tread and yet, when subjected to an outward pressure as
above described, be free and become detached, it and the tread are preferably
constructed as follows:-The lower part of the detachable leg fits in a vertical slot in
the tread so as to prevent the end of the leg moving sideways and in each side of this
slot is a horizontal slot in which two lateral projections formed on the bottom of the
leg fit, which projections secure the tread from moving downwards until the said
lower end of the leg is detached therefrom. Projecting from the inner side of the
said lower part of the detachable leg is a pin, which, when the stirrup is closed, takes
into a corresponding hole in the tread. This pin is split or divided for a short
distance from its outer end or is otherwise formed so as to spring into the said
hole and engaging with it prevent the leg becoming detached from the tread until
the former is subjected to a certain outward pressure as above described.
I sometimes make both legs detachable from the tread similarly as above described
with reference to one leg, the stirrup will then open at either side and the tread be
secured to that leg which does not happen to become detached, or the tread may become
detached from both legs.
I sometimes joint or hinge both of the legs to the tread and make the stirrup to
open at the upper part of the bow in combination with a detachable connection similar
to that above described.

page_text: On the accompanying drawings Fig. 1 represents a stirrup constructed according to
this invention closed and Fig. 2 shews the same stirrup open. Figs. 3, 4 and 5
represent the lower part of the detachable leg and part of the tread of the same on an
enlarged scale and Figs. 6 and 7 shew the same parts separately. The remaining
Figures illustrate modifications of my invention.
The same letters of reference indicate the same parts in all the Figures.
Referring firstly more.particularly to Figs. 1, 2, 3, 4, 5, 6 and 7 A¹ is the leg of which
the lower part is hinged to the tread B and with which the upper part of the bow C
is formed and A' is the detachable leg of which the upper end is hinged to the bow
part C and the lower end is detachably connected to the tread B. An ear a is formed
on the upper part of the leg A* which fits between a pair of corresponding ears con
the bow part of the leg A and through these ears the joint pin d passes to secure
them together. The ears a and c are squared off as shewn so as to make an almost
invisible joint when the stirrup is closed. e is the lower part of the detachable leg A²
which fits in the vertical slot in the tread B thus preventing the leg moving side-
ways and f, fare the two lateral projections formed on the leg A which fit in
corresponding slots g, g in the tread B. h is the split spring pin which projects from
the inner side of the detachable leg A2 and which, when the stirrup is closed, takes into
a corresponding hole i in the tread B. This pin is enlarged near its outer end 2 so that
when the stirrup is closed and that part has passed through the hole the halves of the
pin will spring apart and keep the leg A² in position until it is pressed outwardly as would
be the case by the foot of a rider on being thrown from his horse. The projections f,f
on the leg A2 fitting in the slots g, g transmit the downward strain on the tread B
to the leg A whilst the pin prevents the leg A2 moving outwardly from the tread B
until required. The split pin is by preference formed of a piece of half round steel
wire as shewn by Figs. 8 and 9 which is folded centrally and closed together and the
shank part is then screw threaded and screwed into the hole j in the log A2, the folded
end of the pin is then rivetted over thus firmly securing it in place. The upwardly
projecting parts 62 at the sides of the tread B and between which the legs fit forms
guards to prevent the stirrup being accidentally opened by the pressure of the sole of
the rider's boot; but these parts 62 may if preferred be dispensed with and the tread
made level on the top.
In the modification illustrated by Figs. 10 and 11 the detachable leg A² is formed
with the bow to which the leg A¹ is hinged, the tread B being jointed to the leg A¹
as in the stirrup shewn by Figs. 1 and 2.
In the modification illustrated by Figs. 12 and 13 both of the legs A¹ and A2 are
made separate from the bow part and hinged thereto the tread being jointed to the
leg A¹ and made detachable from the leg A as above described with reference to the
preceeding Figures. Or, instead of the tread B being jointed to the leg A¹ it may be
made detachable therefrom and secured thereto similarly as to the leg A2.
Fig. 14 illustrates a modification of the detachable connection of the leg A² to the
tread B in which projections k, k are formed in the vertical slot 6 of the tread to take
into corresponding transverse slots 1, 1 in the leg A².
Fig. 15 represents a further modification of my invention in which the stirrup is
àrranged to open at the top, the legs A1 and A2 are both hinged to the tread B in the
usual manner and the leg A3 has near its upper end a pin n, which when the stirrup is
closed takes into a hole m in the bow part C, and the split pin fixed to the bow
part C takes into the hole o in the leg A² thus securing the legs in position until the
leg A is subjected to a side strain when the stirrup will open by the leg A' being forced
away from the bow part C.
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 :
1st. In a safety stirrup the improved method herein before described of detachably
connecting the detachable leg to the tread, consisting in the detachable leg fitting in a
vertical slot in the tread the said leg having a side projection or projections which

page_text: engage with a corresponding slot or slots in the tread, in combination with a spring
catch, for the purposes and substantially as set forth and illustrated by Figs. 1, 2, 3, 4, 5, 6
and 7 of the accompanying drawings.
2nd. In a safety stirrup the hereinbefore described modification of the method
claimed by the preceeding claim of detachably connecting the detachable leg to the
tread, consisting in the detachable leg fitting in a vertical slot in the tread the said
leg having a transverse slot or slots which engage with a corresponding projection or
projections on the tread, in combination with a spring catch, for the purposes and
substantially as set forth and illustrated more particularly by Fig. 14 of the accom-
panying drawings.
