PROVISIONAL SPECIFICATION.
An Improved Stirrup.
We, ENOS BOND, of Wade, Auckland, in the Colony of New Zealand,
Storekeeper, and JAMES GOODFELLOW, of Dairy Flat, Auckland, in the Colony
of New Zealand, Farmer, do hereby declare the nature of our invention for
"AN IMPROVED STIRRUP" to be as follows:-
Our invention relates to improvements in that class of stirrups known as
'safety" stirrups, and has for its objects producing a simple and reliable stirrup
which will automatically release the foot of a rider if thrown from a horse or other
animal with more certainty than those hitherto manufactured.
In order that the nature of our invention may be understood we will now proceed
to describe the same in general terms.
In general shape we conform as nearly as possible to that of ordinary riding
stirrups, but instead of making both sides solid with the sole plate on which the
foot bears we hinge one side at its junction with the said plate in such a manner as
to be capable of opening out in a lateral direction.
The other side is solid with the sole plate and towards its upper end is provided
with a joint the pin of which is kept position in the manner following. Upon
the said hinged side and towards its upper part and opposite the said joint is
hinged a horizontal bar which is made slightly bowed or curved towards the front
side and which extends across the stirrup, and is hinged near its center with a
spring joint.
This said spring joint is so constructed as to yield to pressure from the front side
only. The free end of the said horizontal bar is provided with a hinge to receive
the before mentioned joint pin and keep the same in position.

COMPLETE
SPECIFICATION.
An Improved Stirrup.
We, ENOS BOND, of Wade, Auckland, in the Colony of New Zealand,
Storekeeper, and JAMES GOODFELLOW, of Dairy Flat, Auckland, in the Colony
of New Zealand, Farmer, 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:-
Our invention relates to improvements in that class of stirrups known as
"safety" stirrups, and has for its objects producing a simple and reliable stirrup
which will release the foot of the rider if thrown from a horse or other animal with
more certainty than those bitherto manufactured.
In carrying out these objects we make the general shape as nearly as possible
like that of ordinary riding stirrups, but instead of making both sides solid with
the sole plate on which the foot bears we hinge one side at its junction with the
said plate, in such a manner as to be capable of opening out in a lateral direction.
The other side is solid with the sole plate and at its upper end is provided with a
joint the pin of which is kept in position by a check spring until released by the
foot of the rider in the following manner :-Upon the said hinged side and towards
ts upper part and opposite the said joint is hinged a horizontal bar which is made
lightly bowed or curved towards the front side and which extends across the

page_text: stirrup. This horizontal bar has also a jaw with a joint pin fixed therein, which
clasps and fits into the joint on the side of the stirrup. The spring and horizontal
bar are so arranged as to yield to pressure from the front side only.
In order that our invention may be more easily understood we will now proceed
to describe the same, and for that purpose shall refer to the accompanying sheet of
drawings, upon which similar letters of reference indicate corresponding parts
throughout the several views.
Fig. I is an isometrical view of our stirrup when closed.
Fig. II is a view of the same when opened.
Fig. III is a detail view of the catch.
(a) is the sole plate made solid with the side (b) and hinged to the side (c) by the
joint (c) and pin (c²). The side (c) is made solid with the top (d) and is reduced
at (c) to receive the horizontal bar (e) and allow the same to swivel round in a lateral
direction. The top (d) is provided with a slot (d') for the stirrup strap to pass
through and has also a joint (d2) into which fits the end (b) of the side (6). When
the stirrup is closed the pin (e), which is fixed firmly in the jaw (2) of the horizontal
bar (e), passes through the hole (d³), joint (2) and end (61), and with the jaw (e),
which clasps around the joint (d2) holds the parts together, when the stirrup may be
employed in the same manner as an ordinary stirrup. The check spring (f) fits into
a groove as shewn and is provided with a slot (2) to permit of vertical adjustment
and is held by the set screw (f³). This spring falls behind the catch (e³) Fig. III,
preventing the horizontal bar from being opening by jarring, or yielding to light
pressure. When the projecting part of the bar (e) is pressed by coming into
contact with the toe or other part of the rider's foot when thrown from the horse,
the spring (f) easily yields, the horizontal bar (e) is thrown back and the pin (e¹)
withdrawn, releasing the side (6) which falls down as shewn in Fig. II, and frees
the rider's foot.
The materials used may be those employed in making ordinary stirrups and the
spring we prefer to be of steel.
We wish it to be understood that we do not bind ourselves to the exact details
herein described as these may be modified by a skilled workman without departing
from the principle of our invention; for example, the spring (f) may be modified
in many ways and placed underneath the top part (d) if desired.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. In a stirrup such as described herein, a curved horizontal bar such as (e) having
a hinge such as (e), jaw such as (e), having pin such as (el), and having a catch
such as (3), held by spring such as (f) substantially as and for the purposes set
forth and as illustrated.
2. In a stirrup such as described herein, the combination of a sole plate such
as (a) having a side such as (b) and end such as (¹), and having a jaw such as (c)
with a side such as (c) having a pin such as (²), reduced part such as (¹); and
having a curved horizontal bar such as (e) having a hinge such as (e), jaw such
as (2) having pin such as (el) and having a catch such as (3); and having a top
part such as (d), having a slot such as (d') spring such as (f) having slot such
as (2) and screw such as (f³), and having a jaw such as (d2) and hole such as (d³),
substantially as and for the purposes set forth and illustrated.
3. A stirrup constructed, arranged, and operating, substantially as hereinbefore
described and as illustrated on the accompanying drawings.
