AN IMPROVED CHEST EXPANDER
Year: 1884

page_text: I WILLIAM POOL SCOTT of Oxford Grove Manchester in the County of Lancaster
Cashier do hereby declare the nature of my invention for AN IMPROVED CHEST
EXPANDER to be as follows:-
The object of this invention is to manufacture a cheap and efficient "chest
expander" which can be easily put on or off and can at any time be adjusted so as
to give more or less tension on the shoulders as may be required.
The improved chest expander consists principally of two vertical pieces of
webbing or other similar narrow and inelastic material united together by two or
more transverse or horizontal elastic springs (preferably of india rubber) rivetted
sewn or otherwise firmly attached thereto.
The upper end of each piece of webbing above the springs is carried over and in
front of the shoulder, then under the arm and through a loop or opening formed in
or attached to the lower end of the same piece below the springs and the free end
of each piece of webbing is then brought forward round the waist to the front
where they are fastened together by means of a buckle or other adjustable fastening,
by tightening or slackening which the springs can be extended more or less, and
the backward strain of the front of the shoulders be increased or diminished as may
be found desirable.
COMPLETE SPECIFICATION.
I WILLIAM POOLE SCOTT Oxford Grove Manchester in the County of Lancaster
England Cashier do hereby declare the nature of my invention for EXPANDING
THE CHEST, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of this invention is to manufacture a cheap and efficient Chest Expander
which can be easily put on and off and can at any time be adjusted so as to give
more or less tension on the shoulders as may be required.

page_text: The improved Chest Expander consists principally of two vertical pieces of
Webbing or other similar narrow or inelastic materials united together by two or
more transverse or horizontal elastic springs (preferably of india rubber or elastic
Webb) rivetted sewn or otherwise firmly attached thereto.
The upper end of each piece of webbing above the springs is carried over and in
front of the shoulders, then under the arm and through a loop or opening or ring
formed in or attached to the bottom spring, or to the lower end of the webbing below
the springs and the free ends of each piece of webbing are then brought forward
round the waist to the front where they are fastened together by tying or by means
of any suitable adjustable fastenings, by tightening or slackening which the springs
can be extended more or less and the backward strain of the front of the shoulders
be increased or diminished as the case may be found desirable I add to each of the
before mentioned vertical pieces of webbing a pad composed of any suitable
material such pad to be capable of being moved or slided up or down the said
vertical pieces of webbing, and are to serve to obviate any strain which might
occur, either on or behind the shoulders, or arms of the wearer.
To more fully describe my invention I provide the drawings furnished herewith.

before more particularly described.

desired position having been obtained, and the tension from the springs d. d. being
actuated by drawing the webbing a. a through the loops or rings b. b. the wearer
then fastens off by any convenient or suitable means, as shewn at Figure 4.
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
The method of adjusting by dispensing with buckles usually used.
The method of regulating the position of the expander, by means of traversing
through the rings or loops
And the combination of the parts to make an Improved Chest Expander as
herein before, substantially described.
