VULCANIZED INDIA-RUBBER SPRINGS FOR TROWSERS AND BREECHES, WITH INSTRUCTIONS TO ADJUST THE SAME
Year: 1853

page_text: PROVISIONAL SPECIFICATION left by Henry Bentley at the
Office of the Commissioners of Patents, with his Petition, on
the 1st January 1853.
(Void by reason of notice to proceed not having been given within
the time prescribed by the Act.)
I, HENRY BENTLEY, of Spilsby, in the County of Lincoln, do hereby
declare the nature of the said Invention of "VULCANIZED INDIA-RUBBER
SPRINGS FOR TROWSERS AND BREECHES, WITH INSTRUCTIONS TO ADJUST THE
SAME," to be as follows:-
There are two hip springs and a back spring; the hip springs I
insert one in each side seam from the top of the waist to the hip, and
the back spring I insert across the back, near to the top of the waist.
The hip springs answer three purposes: they give elasticity to the
waist, and expand at the hip so as to relieve the pressure on the knee,
preventing the trowsers from bulging. They also act in unison with
the back spring, giving compleat clasticity to the seat; by the arrange-
ment of these springs both trowsers and breeches will be perfectly easy
with braces, which all others have failed to accomplish. I have by
this Invention given free liberty to every position of the body. The
springs require no care or attention by the wearer, and are not visible
when on, being covered by the waistcoat.

page_text: ADDITION TO PROVISIONAL SPECIFICATION.
I, HENRY BENTLEY, of Spilsby, Lincolnshire, do hereby declare the
nature of the said Invention of "VULCANIZED INDIA-RUBBER SPRINGS FOR
TROWSERS AND BREECHES, WITH INSTRUCTIONS TO ADJUST THE SAME," to be
as follows:-
The Invention consists of three springs, namely, two hip springs and
one back spring, made of vulcanized india-rubber and cotton of different
colours to suit the material for which they are used; they are also
made of different sizes; the average size should be for the hip springs
6 inches by 2, and for the back spring 18 inches by 4. I choose
the vulcanized india-rubber for my springs to be made of because
it is not affected by heat or wet. "The hip springs I place one on each
side of the trowsers from the top of the waist to the hip; the back
spring I place across the back, extending from one hip spring to the
other, so that the way the different springs expand. They work in
harmony, and accomplish that most desirable object,-free liberty with
the wear of braces and straps for every position of the body, which all
others have failed to accomplish.

page_text: The A, and B, represent the form of the springs as I have them
made. The strait lines across represent the vulcanized india-rubber,
and the way in which it is to expand. E, represents the form or shape
of the springs when they are placed in the trowsers; they are placed on
the inside, and the seams over which they are placed are left open, so
that whatever extra room may be required it is given, and when it is
not the springs keep the edges of the cloth close, so that it is not visible,
nor does it expand only when required. C, represents the side seam of
a pair of trowsers, and the part where the hip spring is put. D, repre-
sents the back part of a pair of trowsers, and the scat scam where the
back spring is placed.
