UNITED STATES PATENT OFFICE
ANDREW P. DAVIS, OF DALLAS, TEXAS.
TRUSS.
SPECIFICATION forming part of Letters Patent NaI 372,014, dated October 25, 1887.
Application filed August 11, 187. Serial No. 246,667. (No model.)To all zvhon, it may concermz:
Be it known that I, ANDREW P. DAvis, a
citizen of the United States, residing at Dallas,
in the county of Dallas and State of Texas,
5 haveinvented certain new and useful Improve-
ments in Trusses; and I do hereby declare the
following to be a full, clear, and exact descrip-
tion of the invention, such as will enable oth-
ers skilled in the art to which it appertains to
to make and use the same.
This invention relates to certain new and
useful improvements in trusses; and it con-
sists, substantially, in such features of con-
struction, arrangement, and combinations of"
15 parts as will hereinafter be more particularly
described, and pointed out in the claims.
The object of the invention is to provide a
body-band of a truss of a much simplified na-
ture as compared with many former inventions
20 ofa like character, and also of a construction
to fit upon the hip-bones of the wearer,where-
by accidental slipping thereof is obviated or
prevented.
Further, the invention has for its object to
25 simplify the construction and arrangement of
the parts constituting the pads of the truss,
and at the same time render them of a charac-
ter by which the part or parts of the contents
of the abdominal cavity tending to protrn-
30 sion will be more effectually retained in their
proper position than is accomplished with
many pads of prior use or knowledge.
Finally, the invention has such other ob-
jects in view as will more fullyhereinafter ap-
35 pear, when taken in connection with the ac-
companying drawings, wherein-
Figure 1 represents a perspective view of a
truss embodying my invention; and Fig. 2 in-
dicates abottom or plan view of the top of the
40 pad, showing the construction thereof, to-
gether with the arrangement of the springs.
Fig. 3 is a side view of the pad with its cup
removed, by which the arrangement of the
springs is more clearly shown. Fig. 4 repre-
45 sets a longitudinal sectional view on the line
x xof Fig. 2.
Before proceeding with a more full descrip-
tion of my invention, I desire to state that I
am aware of the existence of inventions of
50 this character wherein the pads of the truss
are held against the rupture by the action ofsprings contained within them; but the great
difficulty heretofore has been that the pads
yield too easily at the sides from movements
of the body of the wearer, and consequently 55
allow the rupture to slip out of its cavity. It
is well known that the more movable the vis-
cus the more tendency there is to protrusion;
hence I have concluded that to keep the same
in place the yielding of the pad between the 6o
body and its position on the band should be
in as nearly a straight or direct line as is pos-
sible to be had, yet at the same time to allow
of such pad yielding a sufficient extent later-
ally to accommodate itself to extreme bending 63
of the body,so as not to aggravate the rupture.
The construction and arrangement of the parts
of the pads resorted to by me are such as to ef-
fectually accomplish the result desired, and,
so far as I am aware, substantially differ from 70
anything heretofore devised for the purpose.
Reference being had to the several partsby
the letters marked thereon, A represents the
band, so shaped as to conform as nearly as
possible with the shape of the body of the 75
wearer, and preferably I construct this band
of a piece of metal, a, rounded as shown, and
designed to fit around the abdomen, the said
piece a being slightly flattened at its ends and
having passed therethrough pieces of wire, b,' 8o
that are bent about centrally and have at-
tached to their ends the straps by which the
band is secured in place around the body.
The wires b are slightly spread apart, so that
when the band is in place they act to receive 85
and rest upon the upper portion of the hip-
bone, and in this way little, if any, inconven-
ience is experienced in wearing the truss.
I may resort to other methods of fastening
the wires to the ends of the front piece, a; but 90
I have found everything to answer fully the
purpose by having them united as I have
herein shown.
The pads are constructed of an upper part,
B, and a lower hollow or cup-shaped part, C, 95
each of the said parts being numerously perfo-
rated, as shown, by which a thorough venti-
lation is had and the creation of unpleasant
odors from perspiration and other causes is
prevented. Surrounding the inner edge of the ioo
part C of the pad is a flange, d, on which the
part B rests when in place, and through which
