page_text: I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake and Co., Patent Agents,
Southampton Buildings in the County of Middlesex 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 :-
This invention relates to improvements in drawing boards for the use of draughts-
men, artists and other persons and consists-Firstly, in a board composed of slats
(arranged edge to edge) covered by a connecting sheet of flexible fabric, and provided
at each end with a movable cleat adapted to firmly bind both sides of each slat; and
secondly of a board such as that above described provided adjacent to the ends of the
slats with a series of elevations which when the cleats are removed and the board
rolled up with the undried canvas or paper upon it, will prevent the paint from
coming in contact with the surfaces of the board facing the canvas. The invention
will be more fully understood from the detailed description hereinafter presented,
reference being had to the accompanying drawings, in which
Figure 1 is a face view of the board in condition for use, a portion of the flexible
fabric and drawing paper being removed so as to expose the slats.
Figure 2 a side view of the same rolled, the end cleats having been removed, as
shewn.
Figure 3 a section on the dotted line rx of Figure 2.
Figure 4 an enlarged section on the dotted line y y of Figure 1, and
Figure 5 an enlarged perspective view of one of the lugs D.
In the drawings the separate slats of the board are designated by the letter A ;
these are arranged edge to edge and are covered and connected on their face side by
the sheet of textile or other flexible fabric B, which affords a smooth unbroken
surface upon which to secure the canvas or paper which is to receive the painting or
drawing. Upon the ends of the board are applied the removable cleats C, which are
grooved and fit over the ends of the slats, firmly binding each of same on each of

page_text: b
its sides, and thus preventing each individual slat from twisting or warping and
adding strength and rigidity to the whole structure. The cleats C may be applied
and removed at will, and when removed the board may be rolled up into a small com-
ass for transmission, the cleats being introduced into the centre of the roll or
wrapped on the outside thereof, as desired.
Upon the face of the slats A adjacent to each cleat Care applied the studs Din
series, as shewn, each of said studs in the present instance consisting of a plate of
metal having at its lower edge the projections & serving as pins by which to secure
the stud to its slat, and the oppositely turned lips e which rest firmly against the slat
and sustain the stud in upright position. The present invention is not confined to
any particular form of studs D or to any particular manner of securing them in
position, since these are matters which may be governed by the style, size and
character of the board in connection with which they are to be used. When the form
of studs D shewn in the drawings is employed, it will be found convenient to arrange
them on two lines at each end of the board, the studs on each alternate slat being on
one line, and those on the other alternate slats being on the other line; the purpose
of this arrangement is to prevent the studs from coming in contact with each other
during the rolling of the board, their alternation, shewn in Figure 1, permitting them
to overlap or pass each other when brought into the scroll line produced by the rolling
of the board. The object of the studs D is to afford a space between their upper edge
and the board when the latter is rolled, in which the freshly painted canvas or paper
may be carried without danger of the same becoming disfigured by contact with the
adjacent surfaces of the board. After the board has been used for a study, for
instance, the canvas or paper may be left upon it, being held at one end by thumb
tacks, the end cleats C removed, and the board, with the canvas or paper upon it rolled
up for convenient transmission; the canvas or paper under this condition will closely
hug the surface of the board-that representing the outer parallel line of the scroll-
and be protected at its ends and face by the studs D. The board above described
will be of particular advantage to artists making studies in the country, since they
may conveniently take the board to the scene or object to be represented on the
vellum, canvas or paper, and likewise carry the same home without danger of
disfiguring the newly painted study.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent I declare that what I claim is."
First. The drawing board hereinbefore described consisting of the series of slats
covered on their face by the connecting sheet of flexible fabric and the grooved
removable end cleats adapted to bind each of said slats at its ends on both sides.
Second. The drawing board hereinbefore described consisting of the series of slats
covered by the connecting sheet of flexible fabric, the removable cleats at the ends of
said slats, and a series of studs D arranged on the face of the board, adjacent to each
of its ends.
Third. The drawing board hereinbefore described consisting of the series of slats
covered by the connecting sheet of flexible fabric; the removable cleats at the ends
of said slats, and the series of studs D arranged on the face of the board adjacent to
its ends and each consisting of a flat plate having the pins d and lips e.
