PROVISIONAL SPECIFICATION.
Raising and Lowering Heads, Backs, Arms, or other parts of Couches,
Chairs, Ottomans, and Spring Mattresses.
I EDWIN SPINNEY 118 Old Christchurch Road Bournemouth, Upholsterer, do.
hereby declare the nature of this invention to be as follows
My invention has for its objects
-
First. An easy method of adjusting heads, arms, backs or other parts of couches
chairs &c.
Second. A more rigid method of holding in position when adjusted to
any angle.
In order to carry out these objects I propose to have a metal plate running up and
attached to the head arms, back &c. On either side to be connected with a spindle
which runs across the frame of the couch &c. Upon this spindle is fixed a cog wheel
or similar device on either side-attached to either side of the frame is a cranked rod
of iron which is allowed to swing and fall into the cogs-thus if the head &c. is raised
the cog moves round, & the swinging rod falls into the cogs during the motion so
that when the proper angle or position is reached the swinging rod remains fixed into
the cogs and thus the head &c. is kept in a rigid position-In lowering the head &c.
the rod is simply pulled out of cogs & allowed to drop back again into the cogs when
proper position required is obtained-Thus any position froin horizontal to vertical
can he adjusted.

COMPLETE SPECIFICATION.
Raising and Lowering Heads, Backs, Arms, or other parts of Couches,
Chairs, Ottomans, and Spring Mattresses.
EDWIN SPINNEY 118 Old Christchurch Road Bournemouth Upholsterer 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:
My invention has for its objects
First. A more easy and simple method of raising & lowering the heads, backs,
arms or other parts of couches chairs ottomans & spring mattresses.
Second. A more rigid way of holding them at any angle.
In order to explain these methods I will refer to the subjoined drawings:
(A) is a metal bracket with two circular holes Nos. 1 & 2, one bracket is fixed on
either side of frame inside.
(B) is a metal cog wheel or part of wheel might be used and spindle which turns in
hole No. 2. the end of the spindle is made square and is fixed into a square hole in
plates (C) at No. 3. The upper part of plates (U) is fixed to the head, back or
arm &c. of article which requires to be raised or lowered.
(D) is a cranked metal rod, round or oval or similar the ends of which are inserted
and allowed to swing in holes No. 1. on each side and is so fixed that it drops into
gear into the cog wheels (B) and thus holds the plates C in position.
To raise the head or back &c. is simply to lift up the head back &c. this turns the
cog wheel and thus allows the rod (D) to fall into the next cog or cavity and so on
until the proper angle is obtained.
In order to lower the head or back &c. the rod (D) is pulled out of gear by a piece
of rope (E) or something similar and thus sets the cogs free. When the head or

page_text: back &c. is lowered to proper angle required the rope is loosened and the rod falls
back into gear again and the head or back &c. is held rigid.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I would have it understood
that I do not confine myself to the exact arrangement of all the parts herein
described which may be varied without departing from the nature of my Invention
and I declare what I claim is :—
I. The use of cog wheels or parts of cog wheels.
II. A swinging rod which falls into gear or the cavities of the cog wheels.
III. The method of removing the rod out of gear.
Dated this 2nd day of September 1889.
