Invalid's Convertible Bed-support and Chair.
Mrs. CHARLOTTE BARTON BEYNON, 22, Queens Gate Gardens, S.W., London,
do hereby declare the nature of this invention to be as follows:-
This invention consists of a wooden frame to be placed on the bed of an
invalid. On this frame is hinged a chair-back formed of strong strips of
canvas stretched on a wooden frame. This back can be graduated to any angle
by means of supports hinged to the first mentioned frame and fitting into
racks attached to the back of the chair back frame. The seat, also formed of
a wooden frame which is covered-partially-with canvas and which is attached
to the first named frame by means of screw bolts can also be graduated to any
angle by means of double sets of supports hinged to the under part of the frame
of the seat. The seat is fitted underneath with brass rollers and can be lengthened
or shortened to suit the invalid by adjusting the screw bolts and sliding the
seat backwards or forwards on the lower frame.
An important point in the formation of the seat is the arrangement of the
canvas by which a space is left-in order to avoid any pressure of the spinal
column and which also allows for convenient use of a bed pan without any
change of the position of the invalid.
A moveable headpiece, fitted to the back provides for the support of the head,
when necessary.
Similarly a wooden rest for the feet is connected by bands of webbing to first
named frame.
The arm-rests are removeable at pleasure being dropped into sockets in the
first named frame.
The whole support can be folded flat when not in use.
A wooden table-frame on ball castors with a moveable top provides a bed
table, or a book rest-with a catch to hold an ink-bottle or glass. The legs un-
screw for packing.
The bed-support when placed upon this table and secured by means of two
brass hooks, forms a comfortable bedroom chair.
Dated this 21st day of December 1897.

page_text: declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:—
This invention consists of a wooden frame in four pieces A A A A which can
be put together on the bed, round the patient, the side pieces being near the
centre B and for the length of four inches, six to eight inches in height
diminishing to one inch at each end; the four pieces of the frame are made fast
together by thumb screws, C C C C.
To each of these side pieces at the point B where they are highest are attached
by a double hinge two wooden bars E E and D) D rising vertically; one E E
forming one side of a frame for the seat and one D D the frame of the back
of the bed support which can be raised or lowered by means of legs FF hinged
to the underpart of the frame of the seat and the back and which fit into racks
cut in the side pieces of the first named frame.
The bars forming the frame of the seat E E and back D D of the bed support
are respectively connected and strengthened by curved iron rods, fitted into
grooves, fixed under the ends of the wooden bars of the seat and back.
The G seat of the bed support is formed of strong webbing bound at each
side with leather and having three leathern straps K K strongly sewn on each
side. This seat being passed under the thighs of the patient lying on the bed,
the straps K K are hooked on each side, by means of holes, on to brass pegs
fixed in the sides of the bars EE forming the seat of the bed support; the
legs F F under the seat are then raised to the desired height and the thighs
of the patient are thus raised slightly off the level of the bed. The back H is
formed in the same way as the seat and passed under the shoulders of the
patient and attached in a similar by straps M M way to the bars D D of
the back the supporting legs FF under the back are then adjusted and the
patient will be found to have been raised into a sitting position without any
exertion on his part.
An important point in the formation of the seat is the arrangement of the
webbing by which a space I is left between the seat G and back H in order
to avoid any pressure on the spinal column of the invalid, and which also allows
for convenient use of a bed pan without any change of position.
A moveable head-piece consisting of a slight frame of wood covered with
canvas slips into sockets screwed on to the ends of the bars of the frame of
the back.
Arm rests of wood J are connected by thumb screws, one end to the side of
the frame of the seat, the other to the side of the frame of the back and being
of two pieces hinged together move with the movement of the frame of the
bed support when raised or lowered.
A wooden rest for the feet is slung from the front of the first named frame,
by narrow bands of webbing, adjustable as to length, by a buckle.
The bed support would be made in dimensions proportionate to the size of
the invalid.
A comfortable bedroom chair can be made by placing this bed support on
an invalid bed table made in proportions to support it.
The invalid bed table is made with a top which can be raised or lowered, and
with legs which can be unscrewed for packing and which are fitted with ball
castors.
The invalid bed table is merely an adjunct of the bed support and is not
claimed as a novelty.
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
1st. In bed supports for the purposes herein named the space I, obtained

page_text: by the arrangement of the canvas seat G, and the canvas back H, with the
wooden bars E E and D D.
2nd. In bed supports the employment of the raised side pieces B B in com-
bination with the hinged side bars E E and D D.
3rd. In bed supports the combination of canvas seat G, and canvas back H,
with the straps M M and K K as set forth and shown.
