Improvements in or connected with Drawing Boards.
JAMES DON LICKLEY Millwright and Engineer 413 Old Kent Road
London S.E. 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 :-
In combination with a box or case, a movable cover hereinafter called lid or
protector and drawing board, to protect drawings when not in use fitted also with
spaces to receive square and drawing instruments.
The said lid or protector and drawing board to have crossends tongued and
grooved (a a Fig. 1) to keep it from warping or twisting, also pins or pivots are
fixed to the said lid or protector and drawing board (a, a, Fig. VI) to enable the
easy removal from the position of lid or protector to that of drawing board surface
proper.
The frame is dovetailed together and checked to receive bottom and is provided
with grooves or slots at the inside cheecks of frame (a, a, Figs. III and IV.)
to receive pins or pivots which are fixed to the said lid, or protector and drawing
board.
The said lid or protector and drawing board works on the said pins or pivots:
thus enabling when opened to be drawn along in the said grooves or slots and again
shut in a position the reverse to the former, and thus provide a drawing board
ready for use (b, b, Fig. 1V.)—or it may be arranged by having two pins on one
side of the said lid or protector and drawing board, and slots made in both sides of
frame to correspond with pins so that the said lid or protector and drawing board
may be removed to either side as before (Fig. VII and VIII.)-or it may be arranged
by fitting the said lid or protector and drawing board into the said frame, without
any pins or pivots, with a piece of inpe fastened at each end of the said lid or
protector and drawing board, and when about to be used lifted up and reversed
from the position of the said lid or protector, to that of drawing board surface
proper (Fig. IX and X).
In either case it will be fitted with a lock and key, hasp, or fastener, so that
when the pupil has finished drawing he or she has only to reverse the said
lid or protector and drawing board and lock it when the drawing is secure from
harm.
In the side cheecks of the said frame there is a mortice into which the T square
is passed through (c, Fig. III.) being secured inside with a small pin or fastener,
the said pin or fastener passing through the hole in the said I square, into a hole
made to receive it in the bottom of the said frame (B, B, Figs. I. and II.) thas
keeping all the working edges of the said T square perfect and the stock of the
said square being fastened close up to the said frame insures it being kept
perfectly square. A piece of thin material to be attached to the said drawing
board surface proper with pins to prevent damage to drawings by instruments if
necessary.
In order that my invention may be clearly understood, I will now proceed to
describe the same with reference to the accompanying drawings. Scale on
Sheets 1, 2, & 3 not binding.

I do not limit myself to any particular material used, nor do I confine myself to
any particular mode of arrangement, provided always, that the protector and spaces
for square and drawing instruments be insured in the manner hereinbefore
-described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what I
-claim is.
First Advantages-The said frame, and protector and drawing board, when
shut being light, strong, and neat, takes little more room than any ordinary
drawing board now in use, and that by inserting the key in lock, turning it, with-
drawing the pin from square and reversing the said lid, or protector and drawing
board the work of a few moments, the drawing is ready for use, paper being fixed
in position, likewise having when shut a space of from one quarter to two inches by
the full size of drawing board to hold drawing instruments, drawings &c. thus
-enabling the student to leave his or her drawing at any time unfinished without
fear of damage being done and again being able to commence work at a moments
notice.
Secondly-Novelty-The novelty of the claim consists in the application of lid,
or protector and drawing board, also, the mode of reversing the said lid or protector
and drawing board from that of lid or protector, to that of drawing board surface
proper ready for use, and when in use it occupies exactly the same space as when
shut up.
Dated this 4th day of December 1893.
