PROVISIONAL SPECIFICATION.
Improvements in Pads for Hernia and like Trusses.
I, THOMAS PARTRIDGE SALT, of Corporation Street, in the City of
Birmingham, Surgical Instrument Maker, do hereby declare the nature of this
invention to be as follows:-
My invention relates to the pads of hernia and like trusses and has for its
object, the production of an inexpensive pad which shall be cool to the person,
light in weight, capable of being kept perfectly clean, and cheaply produced.
Heretofore such pads have been made either of a costly material or of a
substance that cannot be kept perfectly clean and therefore objectionable from
sanitary reasons.
One part of my invention consists in making the said pads from china, porcelain,
glazed earthenware or other like ceramic material. The shape of the pad is alike
unto that of a slightly bent pear, with the inner face convexed or cambered and
the edges curved or rounded off, whilst the front part is made hollow, thus leaving
as it were, a shell with the hollow inside following generally the contour of the
inner side of the pad presented next to the person.
The front of the tip end of the pad is formed with a plate or base running partly
up the middle of the said hollowed out part and has wormed holes made within it
for taking the necessary screws for the connection of the attachment band or
carrying strap or the fittings of them.
If necessary the screwed holes may be metal-bushed instead of the ceramic
material being directly wormed.
In carrying out a further form of my improvements, I make the said pads from
glass moulded into the desired figure or hollow figure as before referred to in the
case of ceramic pads, or the connection of the metallic fittings for the straps which
secure the pads to the person may be effected by screws taking into metallic
bushes or fitted insertions.
As a further modification, I make truss pads from vegetable ivory, shaped to
the desired figure and with the front part hollowed out aud formed with a base as
before.
As another modification, I make the pads from stamped metal, either plated or
enamelled. In producing such pade, I take a blank of sheet metal, of the figure
of a slightly bent pear, and cup the same into the desired hollow figure with the
edges turned over and a part turned back to form the plate or base, which has
wormed holes through it for taking the screws which attach the metal fittings of
the truss carrying straps.
In order to produce very light pads, I may make the same from compressed
paper, papier mache, cedar or like wood, cork or other substance, enamelled or
coated with metal by electro-deposition or otherwise, or covered with glass to
render the same non-absorbent. If necessary, layers of asbestos may be interposed
between the body of the truss and the glass or metal coating in order to prevent
the trausmission of heat during the process of fusing on the glass.
As a further modified form of my invention, I may make the said pads of
xylonite or celluloid, moulded into the desired hollow shape as described, with a
bossed part or parts of solid material, which is or are tapped for taking screws in

page_text: connecting the metal or other fittings of the truss thereto, or I may make the said
pad from sheet xylonite or celluloid fashioned into shape by dies and pressure and
with thickened parts left for the attachment of the fittings.
The boundary edges may be rolled or beaded over in any desired way, or if
necessary screwed bushes may be inserted or attached to the material to which the
said fittings are connected.
As a still further form 1 may make the body or base of wood or some such light
material and cover the same with a celluloid facing.
As a still further form I may make the said pad from horn, vulcanite, tortoise-
shell, ebonite or such like substances, with screwed insertions if necessary for the
attachment of usual fittings thereto.

Improvements in Pads for Hernia and like Trusses.
I, THOMAS PARTRIDGE SALT of Corporation Street, in the City of
Birmingham, Surgical Instrument Maker, 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 :-
My invention relates to the pads of hernia and like trusses and has for its object,
the production of an inexpensive pad which shall be cool to the person, light in
weight, capable of being kept perfectly clean, and cheaply produced.
Heretofore such pads have been made either of a costly material or of a
substance that cannot be kept perfectly clean and therefore objectionable from
sanitary reasons.
One part of my invention consists in making the said pads from china, porcelain,
glazed earthenware or other liko cerainio material.
Figure 1 of the accompanying drawing represents a perspective view of a hernia
truss provided with a pad made froin china, porcelain, glazed earthenware or other
like ceramic material according to this form of my improvements.
Figure 2 is a side elevation of the pad separately, and Figure 3 is an elevation
of the broader end of the same.
Figure 4 is a cross section upon the dotted line Figure 2.
Figure 5 is a cross section upon the dotted line ' Figure 2.
Figure 6 is a longitudinal vertical section upon the dotted line Figure 2.
Figure 7 is a plan of the pad and its connection.
Figure 8 is a plan of the pad separately.
Figure 9 is a longitudinal vertical section of the pad and its connection taken
upon the dotted line, Figure 7.
The same letters of reference indicate corresponding parts in the several
figures of the drawing.
The shape of the pad a, is alike unto that of a slightly bent pear, with the inner
face a', convexed or cambered and the edges a curved or rounded off, whilst the
front or outside part a³ is made hollow, thus leaving as it were, a shell with the
hollow inside a, following generally the contour of the side a', of the pad presented
next to the person.
The front of the tip end of the pad is formed with a base a', running partly ap
the middle of the said hollowed out part and has wormed holes a', made within it for
taking the necessary screws b, for making the connection of the base plate 6' thereto.

page_text: The connection of the band, to the pad is made by the tongue 6, taking between
the base plate 6', and a spring pressure plate &, carried by the bridge bracket b'. The
frictional adhesion between the parts is sufficient to hold the pad in its adjusted
position.
If necessary the screwed holes b, may be metal-bushed instead of the ceramic
material being directly wormed.
In carrying out a further form of my improvements, I make the said pads from
glass moulded into the desired figure or hollow figure as before referred to in the
case of ceramic pads, or the connection of the metallic fittings for the straps which,
secure the pads to the person may be effected by screws taking into metallic bushes.
or fitted insertions.
As a further modification, I make truss pads from vegetable ivory, shaped to the-
desired figure and with the front part hollowed out aud formed with a base as
before.
As another modification, I make the pads from stamped metal, either plated or
enamelled. In producing such pads, I take a blank of sheet metal, of the figure
of a slightly bent pear, and cup the same into the desired hollow figure with the
edges turned over and a part turned back to form the plate or base, which has
wormed holes through it for taking the screws which attach the metal fittings of
the truss carrying straps.
In order to produce very light pads, I may make the same from compressed
paper, papier mache, cedar or like wood, cork or other substauce, enamelled or
coated with metal by electro-deposition or otherwise, or covered with glass to.
render the same non-absorbent. If necessary, layers of asbestos may be interposed.
between the body of the truss and the glass or metal conting in order to prevent
the transmission of hent during the process of fusing on the glass.
As a further modified form of my invention, I may make the said pads of xylonite.
or celluloid, moulded into the desired hollow shapo as described, with a bossed or
base part or parts of solid material, which is or are provided with tapped holes
for taking the screws which connect the metal end fitting of the truss band thereto,.
or I may make the said pad from sheet xylonite or celluloid fashioned into shapo
by dies and pressure, suitably thickened parts being left for the attachment of the
fittings.
The boundary edges may be rolled or bended over in any desired way, or if
necessary screwed bushes may be inserted or attached to the material to which the
said fittings are connected, or the attachment may be effected by means of a sliding.
spring as shown in Figure 7.
As a still further form I may make the body or base of wood or some such light
material, and cover the same with a celluloid facing.
As still a further form I may make the said pad from horn, vulcanite, tortoise-
shell, ebonite or such like substances, with screwed insertions, if necessary, for the
attachment of the usual or sliding spring fittings thereto.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. Making pads for hernia and like trusses from china, porcelain, glazed
earthenware, glass or like ceramic material, substantially as and for the purpose.
