Improvements in Drawing Boards.
WILLIAM HERBERT BOND of 24 Prestonville Road Brighton, Art Teacher
nd HENRY REASON of 25 Springfield Road Brighton Manufacturer do hereby
leclare 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
tatement:
This invention relates to drawing boards and apparatus for holding the drawing
paper thereon firmly in place and consists of arms which are held closely at one end
to face of boards by pivots with rivetted heads and which hold the papers in position
by the other end.
To enable our invention to be properly understood we will proceed to fully
describe the same with the aid of accompanying drawings.
Figure 1 is a plan of drawing board with pivotted arms holding paper.
Figure 2 is an elevation showing arm pivotted by rivet.
Figure 3 is a plan of arm.
Figure 4 is a view of that end of arm which grips the paper.
Figures 5 & 6 are elevations shewing different kinds of grips.
Figure 7 is an elevation of arm pivotted to spring clip.
To the drawing board A we attach arms B, by means of rivetted pivots C at one
end in order that they may turn round as required, the other end of arms herein-
after referred to as the grip ends being used to grip the paper and hold it
in place.
The arms B are made preferably of metal, and slightly bowed as shown in
Figure 2, in order to obtain continual pressure on the board and may be made with
ribs in order to stiffen them; to the grip end is attached either claws as shown in
Figure 4, india rubber as shewn in Figure 5, or a roughed surface as shown in
Figure 6, in order that the paper may be held firmly when the arms press
upon it.
When it is desired to hold a large sheet of paper, the grip ends are raised slightly
and moved towards the edges of board, as shown in Figure 1; when it is
desired to hold a small piece of paper, the grip ends are raised slightly and moved
towards the middle of the board as shown by the dotted lines in Figure 1.
The arms may also be attached to the board by being pivotted to spring clips
which grip the edges of board as shown in Figure 7 and may thus be removeable
from off the board.
By the application of our invention, drawing boards can be used made of card-
board, strawboard, or of any other thin, stiff flat material and can thus be made
at smaller expense and will occupy much less space than ordinary wood drawing
boards.
Having now particularly described & ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is―
1. The attachment to drawing boards A of arms B with pivotted rivets at one
extremity and furnished with claws or other suitable gripping surface at the other
end for the purposes described.
2. The combination of pivotted arms attached or attachable to drawing boards,

page_text: with drawing boards of any thin stiff substance, as hereinbefore described &
illustrated in the accompanying drawings.
