Complete Specification Accepted, 3rd Aug., 1888
THOMAS GEORGE DAW Quakers Hall, Sevenoaks Kent Newspaper Proprietor and
Publisher do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of Trusses for rupture, and relates more
particularly to the pad, by means of which the pressure needed can be more effectually
applied.
To this end the pressure of any part of the pad can be increased or reduced, and
applied to the exact locality of the rupture, and to a degree adjustable by, and
according to the feelings of the wearer of the truss.
In an apparatus according to this invention the pad has, inside it, a series of nuts
and shoulder screws, which are capable of being actuated from the outside by means
of levers or other means. The nuts and screws or other appliances for the same
purpose are placed between the stuffing of the pad and its metal frame or frames.
By turning one or either of the screws, its nut causes a projection or graduated
swelling of that part of the pad against which the nut is forced.
It will be evident that other means than those described may be employed to
produce this differential or variable pressure from the pad.
Dated this 2nd day of September 1887.

THOMAS GEORGE DAW Quakers' Hall, Sevenoaks, Kent Newspaper Publisher and
Proprietor 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 :-
This invention relates to the construction of Trusses for Rupture, and relates more
particularly to the Pad, and the means by which the sufferer of the complaint can
make his own feelings the guide to obtain perfect adjustment of the pad, by the
application of the needed. pressure on and around the exact seat or source of his
suffering.
To this end any part or extent of the surface of the pad can be applied and regulated
by the wearer of the truss himself instead of the maker of the truss.
In an apparatus according to this invention the pad frame has double or single
plates of iron or other metal 1, between and through which is arranged a series of
screws, carrying projectors or nuts 2, actuated by ring or other levers 8. The ends
of the projectors are fitted with caps of extended area 4. The inner plate of the
double frame has square holes 5 of the size of the body of the projectors through
which the projector works and by which it obtains stability and accuracy of movement.
The screw on and through which the projector is actuated is formed with a shoulder
by the continuation of a smaller spindle attatched to it 6.
The outer plate is pierced with round holes on which the spindles act 7.
The spindles are drilled with holes for the reception of the levers to turn them.
The wearer of the truss by turning the lever causes the projector to raise the
padding to any extent required, the pressure being thereby increased on that part
against which it acts, and as the whole area of the pad is subject to the influence of
all or any of the projectors the pressure can be applied on the exact part of the
upture the wearer feels it to be necessary.
r
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 what my
claim is
1st. The utilisation of the patient's feelings and sensations by which the wearer of
a truss can, through the medium of screws and projectors, perfectly adjust the pad
himself instead of leaving it to the maker of the Truss.
2nd. The use, for producing differential pressure to any degree or on any extent
of the surface of a truss pad, of apparatus consisting of nuts or projectors, with screws
and levers and for the means of actuating the same that by turning either of the
screws by its lever the nut or projector is forced forward, producing a raised surface
on the pad against which the projector acts to the required height and pressure.
3rd. The use for securing perfect accuracy in the application of the pressure on
the parts affected, of a pad frame consisting of two plates. The inner plate being

page_text: pierced with openings of the size and shape of the projectors to act as guides and to
secure stability of the movements of the projectors. The screws have shoulders
formed at the head of the thread by a continuation of the metal reduced in size, the
end of this spindle being pierced for the reception of the ring lever. The outer plate
of the frame is pierced with round holes through which the screw spindles pass. The
shoulder of the screw therefore obtains its resistance against the inner part of the
plate. By turning the screw the padding is forced out by the projector and the
pressure thus caused is applied by the wearer to the parts needed.
4th. The use for commanding the whole area of the pad of any number of
projectors necessary for the size of the pad.
5th. The use of the same apparatus in single plates.
