SIR WILLIAM BAKER, OF AUSTIN, TEXAS.
Letters Patent No. 107,648, dated September 27, 1870.
IMPROVEMENT IN TRUSSES.
The Schedule referred to in these Letters Patent and making part of the same.I, Sit WI~LLrrA BAKER, of Austin, in the county
of Travis and State of Texas, have invented certain
Improvements in Self-adjusting Trusses, of which the
following is a specification.
Nature and Objects of the Invention.
The first part of my invention relates to a combi-
nation of steel wires, secured in parallel position with
each other by transverse bars, to which each wire is
secured, forming a belt which is made to fit to the
body. The wires, of which there may be five or more
in number, combined, afford sufficient elasticity to
conform to tihe shape of the human pelvis. The ends
of, the wires are secured between two metalIic plates,
into grooves made to receive them.
The second part of my invention'consists of a metal
plate, to which the pads are attached, armed with two
flanges projecting at right angles near the end of the
plate from its inner edge, at the ends of which Lare
transverse lugs or ears, working over the edge of the
plate to which the wires are secured. The two plates
are held in position by a screw. At the end of the
upper plate an arm rises at right angles, to the end of
which is secured a ball. This ball is seonred to the
pad in this manner: From the inner surface of the
pad rises a stud or stump, at the top of which a con-
cave circular depression forms a socket, in which the
ball rests, secured by a metallic cup, through which
tihe arm (to which the bail is attached) is projected,
through an orifice in its bottom.
Description of the Accompanying Drawing.
Figure 1 is a side elevation of the machine embody-
ing my inveutiom.
Figure 2 is a vertical transverse section, showing the
method by which the pads are secured.
Figure 3 is a section of a side elevation, showing
how the slide is secured.General Description.
A A are the wires forming the spring.
B B, transverse bars lto which the wires are se-
cured.
L, plates fastened together, clasping and securing
the ends of the wires, the wires resting in grooves, so
as to be flush with the inner surface of the plates.
D, plate to which the pad E is secured.
F, arm, with the ball G attached.
Hf, metal cap, which secures the ball Gt in its socket
0, screwed over the hall on the stud or stump J.
The plate C is secured so as to slide underneath
the plate D, hy the lugs or cars I I.
The screw K, passing through the plate D, enters
the holes perforated into the plate C, securing the slide
in any desired position.
leainms.
I claim as my invention-
SThe combination of wires A A, forming a spring,
secured in parallel position and in desired distances
from each other, by the cross-bars, substantially, and
for the purpose hereinbefore set forth.
2. The combination of two plates, with parallel
grooves ip their surface, into which the wires rest,
and secured by being clasped between the two plates,
admitting of their removal aid replaced by others,
substantially, and for the purpose hereinbefore set
forth.
3. The stud or stump rising from the center of the
disk E, with the concave circular depression on its
top, forming a socket to receive the ball G, and also
furnished with a male screw, for insertion into the
metallic cap II, to secure the ball in its socket, all ar-
ranged as described.
