Manchester Square London W. Surgical Instrument Makers do hereby declare the
nature of this invention to be as follows:-
The object of this apparatus is to keep or replace the great toe in its normal position,
thus preventing bunions.
It consists of a thin metal lever between and inch wide, covered with leather,
to be placed under the foot, reaching from the middle of the great toe to the end of
the arch.
Its fulcrum is kept in place behind the joint of the great toe by a small upright
plate, jointed to it, softly padded and provided with a hook.
At its terminal end the lever embraces the great toe from underneath and outside,
whilst a soft leather strap with holes surrounds it inside and above and is then fastened
to a hook at the outside; thus closely adapting the lever to the toe.
From the toe to the fulcrum the lever forms a large curve, whereby the joint of the
toe is guarded against pressure and another slight one from the fulcrum to its end,
at which an elastic or non elastic band is fixed in an angular position, in order to pull
the inverted toe outside.
The band is then passed across the instep, brought round the ankle and secured to
the hook on the small upright plate.
In bending the foot up and down the apparatus acts as a spring, readily yielding
to every movement and straightening the foot without impediment or discomfort in
walking.

Manchester Square London W. Surgical Instrument Makers 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 :-
-
The object of this apparatus is to replace the great toe, which has been forced,
mostly by ill-fitting boots, upon or under the second toe, to its normal position, and
thereby to prevent the formation of, and to reduce the size of an already formed
bunion.
The lever A is made of metal, from three eighths to half an inch wide, covered with
leather, and of different lengths, according to the various sizes of the foot. It is worn
under the foot and reaches from the middle of the great toe to the end of the arch.
The fulcrum B of the lever A consists of a small, well padded, rectangular plate,
jointed to it, which grasps the side of the foot just behind the joint of the great toe.
To avoid pressure upon the joint of the great toe, the shape of the lever is nearly
semi-circular from the fulcrum to the great toe, to which it is attached by a soft
leather strap C. At the other end of the lever a longer band D is fixed at a right
angle, which, after traction being made, is passed over the instep, then round the
ankle and fastened to a small hook on the fulcrum plate B. Thus applied the
apparatus can be worn with comfort in any boot.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :
1. The lever A which is placed under the foot, for the purpose set forth in the
preceeding description.
2. The small rectangular plate B which acts as fulcrum, in the manner described.
