IMPROVEMENTS IN. TRUSS PADS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I JAMES ARNOLD of the firm of Arnold and Sons of West Smithfield in the
City of London, Surgical Instrument Makers do hereby declare the nature of said
invention for "IMPROVEMENTS IN. TRUSS PADS" to be as follows:-

I
:
The invention consists in hinging a plate to which the pad is connected to the
plato now known as the pad plate; between the two plates there is a regulating
spring, the tension of which is regulated by the application of such a spring as may
possess the necessary power required. The pads may be made of wood, vulcanité,
india rubber inflated or solid, when inflated I fill the pad with glycerine 'in pre-
ference to water, " moc-main," air or other pad filling now in uso.
The use of
glycerine for the filling is applicable to all kinds of truss and pessary pads.

I, JAMES ARNOLD of the firm of Arnold and Sons of West Smithfield in the
City of London Surgical Instrument Makers do hereby declare the nature of said
invention for "IMPROVEMENTS IN TRUSS PADS and in what manner the same is
to be performed to be particularly described and ascertained in and by the
following statement :—
The invention consists in hinging a plate to which the pad is connected to the

spring, the tension of which is regulated by the application of such a spring.
as may possess the necessary power required. The pads may be made of
wood, vulcanito, india-rubber, inflated or solid, when inflated I fill the pad with
glycerine in preference to water moc-main, air, or other pad filling now in
use. The use of glycerine for the filling is applicable to all kinds of Truss and
pessary pads.
Figure 1 of the accompanying drawings is a perspective view of a truss con-
.structed according to my invention. Figure 2 is a view in plan of the plate to
which the pad is connected. Figure 3 is a plan of what is usually called the pad
plate and Figure 4 is a view in sectional side elevation of the pad plate and the
plate to which the pad is connected but the pad. is removed and showing the
spring between the two plates. Figure 5 is a perspective view of the same or of a
similar truss showing the spring in a somewhat different position to the previous
Figures but still between the two plates as before. Figure 6 is a plan of the latter
looking on the plate to which the pad is attached. Figure 7 is a plan looking on
the other side or on what is generally known as the pad plate and Figure 8 is a
side elevation of the same Similar letters of reference refer to like parts in all the
Figures. a is the plate commonly known in trusses as the pad plate, b is the
plate to which the pad is connected which plate is hinged as shown to the plate a
in any convenient manner.
I have shown in the drawings two ways of connecting these plates together by
joints or hinges although they may be jointed in other ways if found convenient
the two ways shown however sufficiently illustrate how this may be done. c is the
spring between the two plates a and b. In the perspective view I have shown the
pad on the plate b, and I have also shown the pad in section in connection with
Figure 8 so as to clearly illustrate the filling of same which may consist of
glycerine, water, moc-main, air or other pad filling. The drawing however is
intended to show the pad as filled with glycerine which I prefer.
The tension of the spring can be regulated according to the power required.
Trusses constructed in the manner described can be worn with the greatest comfort
while at the same time giving the necessary support where requisite.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
"
In truss pads the combination of the plates a and b with springs c and when
inflated pads are used inflating the same with glycerine all substantially as and for
the purposes set forth.
