TRUVIDIONAL SPECIFICATION.
Improved Truss Pad.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Charles Leonard, of Glover, Vermont, U.S.A.
Inventor,) to be as follows:-
This invention relates to an improved truss pad which is more comfortable to
wear and more effective than those trusses at present in use.
A truss pad made in accordance with this invention consists of a circular holder
preferably made of wood and having a convex outer face and a concave inner face.
The holder is provided on its concave side with an annular inwardly-projecting
flange. A convex clastic or rubber cushion provided with an air vent is held in
place with its periphery under the annular flange aforesaid in such manner that the
convexity of the said cushion projects beyond the flange, so that the cushion bears
on the hernia, and the annular flange has a support on the surrounding parts.
A pad thus formed is secured by a screw-pin or other means to suitable bands or
straps whereby it is retained in position upon the wearer's body.

COMPLETE SPECIFICATION.
Improved Truss-pad.
1, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Charles Leonard, of Glover, Vermont, U.S.A.
Inventor,) and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to an improvement in truss-pads for use with surgical
trusses of various kinds and for various purposes, the object thereof being to
provide a simple, cheap, novel, and serviceable pad, which may be capable of being
so located upon the ruptured part as to exert an even gentle elastic pressure
thereon and yet be held firmly and immovably, so that during the movements of
the person it may not become displaced from its proper position, and so that no
injury may insure to the ruptured part as the results of such movements; and the
invention consists, essentially, in the combination, with a flanged holder of a soft
clastic cushion so connected to said holder that the cushion may bear upon the
hernia, while the annular face of the holder has a firm bearing upon the abdomen
directly around the hernia, (or against the flesh surrounding any other ruptured
part, as the case may be); and the invention further consists in the construction,
arrangement, and combination of parts, substantially as will be hereinafter
lescribed and claimed.
In the accompanying drawings, illustrating my invention, Figure 1 is a plan view
of my improved truss-pad. Fig. 2 is a cross-section of the same.
Like letters of reference denote like parts in both figures.
In carrying my invention into practical effect I first provide a holder A,
onsisting of a circular plate. This is preferably convexly curved on the outer
de thereof, while on the inner side it is concaved to a greater or less degree. The
[Price 8d.1

page_text: concaved side of the plate A is formed with an annular flange u, projecting inwardly
a slight distance over the concaved face. This annular flange a forms, therefore, a
smooth annular or ring surface adapted to be brought in contact with any desired
object, and thus adapted to surround a hernia or ruptured part and bear firmly
upon the parts adjoining thereto, while the hernia or ruptured portion lies in close
and easy contact with the cushion carried on the concaved face of the holder. This
holder may be of any desired material-such as vulcanized rubber-and it
of any proper and useful form, outline, and shape, it being only necessary that it
should have an annular flange, or surface, which may have a firm solid bearing
upon the parts surrounding the hernia.
may be
B denotes a soft elastic rubber cushion consisting of a small convexed circular
sheet of suitable rubber or other soft, yielding, or elastic substance. This rubber
is of suitable size, so that its peripheral edge may fit neatly within the concaved
face of the holder A and under the annular flange a. Said rubber cushion is
adapted to be sprung into place, where its own elasticity holds it and keeps it
properly positioned, its convexity being presented outward, while its concave face
is opposite the concaved face of the holder A. Thus it will be seen that the elastic
cushion B may be pressed inward by any object acting thereon from without, and
that there will be plenty of room within the concave holder to permit of such
inward pressure to as great an extent as may be desired, and even until the annular
flange comes in contact with the pressing object and prevents the further inward
movement of the elastic cushion. Said elastic cushion is provided at any suitable
point as, for instance, at a point near the periphery as shown in the drawings,
with an air vent or opening. This air vent or opening is deemed necessary, as
the combination of the holder A. and the elastic cushion B with the air-vent b form
in reality what may be termed an "air-pump," the operation of which produces a
suction when it is applied to a hernia, which suction helps to hold the truss in place
with less pressure from the belt or other device employed for keeping it in
position on the person.
C denotes a screw, which enters a central opening in the holder A and is adapted
to be used for the purpose of connecting the holder to a strap or other device by
means of which it may be held in position.
The use and advantages of a truss-pad constructed in the manner which I have
just described will be apparent to those skilled in the art from the foregoing
description of its structural arrangement and combination of parts. It will be
clearly manifest that when this pad is to be applied to a ruptured part the soft
elastic cushion will be brought into contact with said ruptured part and pressed
closely against the same, while the annular flange a will be made to bear upon
the contiguous surface of the abdomen or other part. This bearing of the annular
flange upon the surface surrounding the hernia will serve to keep the pad fixed
and immovably in place during the various movements of the person wearing the
truss, and will prevent any displacement of the soft elastic cushion from its bearing
on the hernia, which often occurs with elastic pads now in common use, and which
would occur with any elastic pad not provided with this annular flange, which
provides the bearing aforesaid.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that
what I claim is :
1. In a truss-pad, the combination, with the circular holder having an annular
flange, of an elastic cushion held under said flange and adapted for use so that the
said cushion may bear upon the hernia while the said annular flange bears upon the
surrounding parts, substantially as and for the purpose described.
2. In a truss-pad, the combination, with the holder having a convex outer face
and a concave inner face and provided. on the concave side with an annular
inwardly-projecting flange, of the convex elastic cushion provided with an air-vent

page_text: and held in place with its periphery under said annular flange, the whole device
being adapted for use, as stated, with the cushion bearing on the hernia and
the annular flange having a support on the surrounding parts, substantially as
described.
