Device for Preventing Falling of Horses in Two Wheeled Vehicles
and others,
I, ADELA KEYS, of 30, Fopstone Road, Earls Court, S.W., no calling, do hereby
declare the nature of this invention to be as follows:-
Two small wheels are fastened to two perpendicular poles attached one to each
shaft near the belt of the horse. These can be held in position each by two other
poles or rods forming a toggle joint & moved by wires pulling each way, or by wires
fastened directly to the ends of the perpendicular poles near the wheels and also
pulling in two ways. In the case of the toggle joint and describing one side
only two poles with one end of each joined by a hinge are fastened at the
other ends, one to the fastened end or base of the shaft & the other to the foot of
the perpendicular pole near the small wheel. When not in use the pole described
as perpendicular can be pulled up by pulling the hinge of the toggle by a wire
drawing from under the toggle joint; to place in position again a wire fastened
above the joint can be pulled until the two poles hinged are straight, by which
the wheel is placed in position & also is held secure from moving.
The perpendicular poles are hinged so that they do not move sideways and to
strengthen the hinges, a trace or slight girder is placed over the horse from one
hinge to the other & also fastened to the shafts.
The wheel can be made on a swivel or as in a castor. Also the wheels ordinarily
can be fixed a few inches from the ground but could be lowered on to the ground
by a separate lever or wire fastened to the perpendicular pole.

Device for Preventing Falling of Horses in Two Wheeled Vehicles
and others,
I, ADELA KEYS, of 30, Fopstone Road, Earls Court, S.W., do hereby declare
the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
This invention relates to means for preventing draught horses falling on slippery,
surfaces and comprises a sling attached to the shafts of the vehicle, and a pair
of props or supporters jointed to the shafts and adapted to be brought (when likely

page_text: to be required) into such position in proximity to the ground and to be retained in
such position by toggle-acting struts as to hold up the shafts and thus support the
weight of the horse in case of the animal slipping.
The invention will be described with reference to the accompanying drawings
wherein Figure 1 is a side elevation and Figure 2 a front elevation of the device.
AA are a pair of props or supporters formed of tubes suitably trussed, as
shewn, so as to ensure rigidity and terminating in wheels B (preferably swivelling
or castor wheels) the props A being pivoted at a to brackets C upon a girder-like
yoke D attached to the shafts and bridging over the back of the animal. The
props are capable of being raised out of operative position as indicated in dotted
lines and of being lowered until the wheels are within a few inches of the ground,
and of being rigidly held in readiness to act, by toggle-jointed struts E jointed
to their lower ends and to fixed points on the vehicle, the middle joints e of the
toggles being knee-joints capable of passing just beyond the line of centres so as to
ensure the necessary rigidity. In order to strengthen the joints a of the props
and prevent splaying, the latter are provided with upward extensions or tail
pieces A which are engaged in forked brackets C¹ on the yoke D when the props
are brought into operative position. The raising and lowering of the props is
effected from the driver's seat through the medium of wire rope connections F
passing over suitable guide pulleys and attached to the middle joint of each of the
toggle struts, the two being operated either simultaneously or separately. G is
the sling attached to the shafts and passing freely under the body of the animal
in position to receive his weight when he falls.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is: :-
The herein described means of preventing draught horses falling, consisting in
the combination with the shafts of the vehicle, of a supporting sling a yoke
bracing the shafts, and a pair of props or supporters adapted to be brought and
held by toggle-jointed struts in position to support the weight of the horse sub-
stantially as set forth.
