PROVISIONAL SPECIFICATION.
Improvements in Adjustable Bed Trays.
I, SAMUEL CLARKE of the Pyramid Works Childs Hill in the County of Middlesex
Night Light Manufacturer do hereby declare the nature of this invention to be as
follows:-
My improvements relate mainly to adjustable bed trays which are carried by
an arm that is jointed to a clip formed to clip the upright post of a bedstead.
The tray I form as heretofore with side and end pieces rising up from it to a
sufficient height to form a shade to shade the person in bed from the light from
a food warmer or night light placed on the tray. The side and end pieces around
the remainder of the tray I make of a height sufficient only to prevent articles
placed on the tray from slipping off it.
I provide a sloping reading desk or book support to be carried by this portion of
the tray. The narrow ledge at the bottom of the sloping back of the desk I make
long enough to be placed at an angle across the tray and to rest upon the top of the
side rim pieces. I also make slots across the underside of the ledge of the desk or
hook support for the top edge of the side rims of the tray to enter and I make
these slots at an angle across the bottom of the ledge so that the desk will stand
The back of the desk I
across the tray in a correspondingly inclined position.
provide with a supporting leg jointed to it which can be turned outwards from the
hack to rest upon the tray and hold up the desk. Or the desk can be supported at
the top of a short rod that can be fixed in the tray, the desk being jointed to the rod
by a cup and ball joint so that it can be turned into any position required.
For carrying medicine bottles and such like I provide a small open box to hook
on to the outer side of the high end of the tray or this box may be made in one piece
with the tray. Everything required by an invalid can in this way be carried by the
tray.

COMPLETE SPECIFICATION.
Improvements in Adjustable Bed Trays.
I, SAMUEL CLARKE, of the Pyramid Works, Childs Hill, in the County of Middlesex,
Night Light Manufacturer, 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 improvements relate mainly to adjustable bed trays which are carried by an
arm that is jointed to a clip formed to clip the upright post of a bedstead.
The tray I form as heretofore with side and end pieces rising up from it to a
sufficient height to form a shade to shade the person in bed from the light from
a food warmer or night light placed on the tray. The side and end pieces around
the remainder of the tray I make of a height sufficient only to prevent articles placed
on the tray from slipping off it.
I provide a sloping reading desk or book support to be carried by this portion of
the tray. The narrow ledge at the bottom of the sloping back of the desk I make
long enough to be placed at an angle across the tray and to rest up the top of the
upon
side rim pieces. I also make slots across the underside of the ledge of the desk or
book support for the top edge of the side rims of the tray to enter and I make these
slots at an angle across the bottom of the ledge so that the desk will stand across the
D..

page_text: tray in a corresponding inclined position. The back of the desk I provide with a
supporting leg jointed to it which can be turned outwards from the back to rest upon
the tray and hold up the desk. Or preferably I support the desk at the top of a short
rod that can be fixed in the tray the desk being jointed to the rod by a cup and ball
or universal joint so that it can be turned into any position required.
For carrying medicine bottles and such like I provide a small open box to book
on to the outer side of the high end of the tray or this box may be made in one
piece with the tray. Everything required by an invalid can in this way be carried
by the tray.
Figure 1 is a side elevation and Figure 2 a plan of an adjustable bed tray con-
structed in the manner I prefer for carrying out my invention.
A is the tray formed so that it can be slidden to and fro along an arm B which is
jointed to a bracket which can be secured by clamps to the iron uprights of the
head of a bedstead. One end of the tray is formed with raised sides to form a shade
for any light placed on to that end of the tray whilst around the remainder of the
tray the side and end pieces are only of sufficient height to prevent articles from
slipping off. D is a reading desk with a projection D¹ from the back which is
jointed by a horizontal joint E to the top of a vertical rod which can turn within a
hollow vertical standard F fixed to a bed plate G. H is a binding screw by which
the vertical rod can be locked and prevented from turning. The bed plate G is not
a fixture to the tray but its ends pass into undercut grooves at the sides of the tray
as best seen in Figure 3 which is a cross section of the tray and plate G-the bed
plate is so held securely-if however the plate be slidden towards the covered end
of the tray the ends of the bed plate pass out from the undercut grooves and the
bed plate and reading desk can then be lifted away. I is an open box hooked on to
the high end of the tray as above mentioned.
At Figures 4 and 5 I have shown how the desk may be retained by the side rim
pieces of the tray as first mentioned. In these figures D is the reading desk-D a
leg jointed to it at the back and D³ grooves cut at an angle across the underside of
the bottom ledge of the desk to fit over the side rim pieces of the tray when the
desk is placed at an angle across the tray as shown. The grooves are seen in Figure 6
which is an underside view of the bottom ledge piece of the desk.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
claim is :-
1. An adjustable bed tray formed with removeable desk or book support sub-
'stantially as herein before described.
2. The construction of adjustable bed trays substantially as herein before described
and illustrated in the drawing annexed.
Dated this 3rd day of August 1889.
