Improvements in Trusses.
A communication from LOUIS NEWTON SMITH, Yeoman, residing at Toronto, in the
County of York, in the Province of Ontario, Canada.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.,
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 invention is to provide a neat, simple and effective truss one
which can be easily adjusted without unnecessary pressure to suit all forms of hernia,
and which from its simplicity gives entire freedom of movement and comfort to the
wearer without danger of displacement and the invention consists essentially of
forming the truss of one continuous rod of wire curved to fit the body and bent at
the back into the form of a loop or ring which may be covered with chamois or any
other suitable material and at the front end coiled into a rigid open spiral thus
forming an open frictionless pad of any preferred shape. To hold the truss in place
I attach to the curved rod or wire, above the rear pad or loop a web or partial belt
which passes around the body to the front pad and is there held by a loop passing
over a button on the front pad.
The accompanying drawing is a perspective view of the improved truss in the
position in which it is applied to the body and as seen from the front, and Fig. 2
is a transverse section of the same on the line y-z fig. 1, looking in the direction. of
the arrow and with the partial belt B omitted."
The improved truss consists of a U-shaped continuous rod or wire A curved to fit
the body at a and coiled at the front end into a rigid open spiral A¹ of any preferred
shape to form an open frictionless pad to fit the rupture and bent at the back into
the form of a loop A' which may be covered with chamois or any other suitable
material.
To the rod or wire A above the rear pad or loop A² is attached a web or partial
belt B which passes around the body of the wearer and is attached at its front end
by a loop B or equivalent to a button A3 formed on the end of the wire A turned
outward at the centre of the pad A. When the truss is adjusted the front pad A¹
is applied to the rupture and the bow or curved portion a rises nearly upright and
passes over the point of the hip below the lower rib and the rear pad or loop A³
presses into the soft muscles of the hip and affords a bearing, thus securing perfectly
the rear end of the truss.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. A truss consisting of a continuous rod or wire curved to fit the body and
coiled at the front end into a rigid open spiral to form the pad and bent at the back
end into the form of a loop substantially as and for the purpose set forth.
2. A truss pad made in one continuous piece with the bow by coiling the wire
into suitably shaped spirals substantially as and for the purpose set forth.
3. The combination of the front pad A' bow a rear loop A' web or partial belt B
and button A substantially as and for the purpose set forth.
Dated this 22nd day of April 1890.
