PROVISIONAL SPECIFICATION.
Improvements in or connected with Drawing Boards.
I, EDITH SOPHIA ANSTRUTHER, of The Mount, Thorne Road, Doncaster, in
the County of York, Art Teacher, do hereby declare the nature of this inven-
tion to be as follows:-
My invention refers to drawing boards, and my object is to so construct the
same that they may be readily adjusted and fixed at any desired angle, whilst
at the same time the general arrangement and construction of the said board
is most compact and useful, making it especially suitable for use in art
classes.
According to my invention, I employ a tray or shallow box having a lid
formed with a drawing board surface hinged to one of its sides, and in the side
of the lid I attach a metal or other suitable slide having a dovetailed groove
within the same. A distance arm which is fulcrumed at one end to the side
of the tray, is connected at its opposite end, by means of a clamping screw, to
the dovetailed slide on the side of the lid, in such a manner that by unclamping
the screw the lid may be adjusted to any angle and then be fixed by means
of the screw. Two distance arms may be employed if desired on opposite sides
of the lid, and by providing the lid with detachable hinges at its side and end
it may be employed tilted from its side or its end as desired. The clamping
screws would in this case be detachable and they could be formed with locking
shoulders to hold them in position in recessed plates situated on the sides of
the tray or lid.
India rubber feet or pads may be attached to the base of the tray for sup
porting the same on a desk or table. For clay modeling I provide
plate having pins in the same for attachment to the drawing board.

Improvements in or connected with Drawing Boards.
I, EDITH SOPHIA ANSTRUTIER, of The Mount, Thorne Road, Doncaster, in
the County of York, Art Mistress, 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 refers to drawing boards, and my object is to so construct the
same that they may be readily adjusted and fixed at any desired angle, whilst

page_text: at the same time the general arrangement and construction of the said board
is most compact and useful, making it especially suitable for use in art
classes.
In order that my invention may be readily understood, I will describe same
with reference to the accompanying drawing in which Figure 1 illustrates in
front and Figure 2 in side elevation, a drawing board arranged and fitted
according to my invention.
Figure 3 shows in side and Figure 4 in front elevation a modified construc-
tion of my invention.
31.
Figure 5 illustrates a detail of construction.
Referring particularly to Figures 1, 2 and 5 of the drawings, I employ a
shallow box A to which is hinged a board or lid B, which may be provided
with a drawing board surface; or as illustrated in Figures 1, and 2, the lid B is
constructed as a drawing board. In one side of the board B I fit a slide C,
preferably made of metal, and formed with an interior groove as clearly shown
at Figure 5 of the drawing. A distance arm is fulcrumed at the side of
the box A, and is connected at its opposite end, by means of a clamping
screw E, to the slide C in such a manner that by unclamping the screw, the
lid B may be adjusted to any angle and then fixed by means of the screw E.
Referring to Figures 3 and 4 of the drawing I have shown a tray A, to
which the drawing board is hinged, and which is fitted with a distance arm,
not shown, in the same manner as above described with reference to Figures 1, 2
and 5. The tray A may consist of a plain board or be formed as an open
framework; and the drawing board may be constructed having a supporting
framework G enclosing a board, slate or composite centre H, which may be
arranged to slide in grooves in the side members of the framework G, thus
rendering the centre portion capable of being readily taken out, if required
to be removed or reversed.
Two distance arms such as A may be fitted and arranged upon opposite sides of
the drawing board for supporting it, and by providing the lid with detachable
hinges at its side and end, it may be employed tilted from its side or its end
as desired. The clamping screws would in this case be detachable, and they
could be formed with locking shoulders to hold them in position in recessed
plates situated on the sides of the tray or lid.
India-rubber feet or pads F, may be attached to the box or tray A, such
feet consisting of pads as shown in Figures 1 and 2 or strips as shown in
Figures 3 and 4.
It will be readily seen that the drawing board may be adjusted so as to lean
over or away from its supporting base, and may readily be provided with
retaining devices for holding drawing paper, drawings, and such like, upon
either its inner face or upon its outer surface as desired. A handle should be
provided upon one side of the box or framework to make it convenient to
carry; and an auxiliary catch may be fitted to retain the two parts in their
closed positions.
If clay modelling is to be done, it is preferable to cover the board with a
metal plate, which may be retained in position by means of pins.
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:-
1. A supporting base having a drawing board hinged thereto, a distance arm
fulcrumed at the side of the supporting base, and connected at its opposite end
by an adjustable clamping device to a slide, arranged upon the side of the
hinged drawing board, substantially as and for the purposes herein set forth.
2. A supporting base having a drawing board hinged thereto, distance arms,
arranged and acting substantially as herein described, fitted upon opposite sides
of the drawing board, substantially as and for the purposes herein set forth.

page_text: 3. The general arrangement, construction and combination of parts consti-
tuting my invention relating to drawing boards substantially as herein described
and illustrated with reference to Figures 1 and 2 of the accompanying drawing.
4. The general arrangement, construction and combination of parts consti-
tuting my invention relating to drawing boards substantially as herein described
with reference to Figures 3 and 4 of the accompanying drawing.
