PROVISIONAL SPECIFICATION.
Improvements in Sketching Boards used by Painters and the like.
1, ALFRED EDWARD RIGG, of 5, Victoria Terrace, Fagley Road, Eccleshill,
near Bradford, in the County of York, Fine Art Dealer, do hereby declare the
nature of this invention to be as follows:-
"
This invention relates to improvements in the boards or wooden panels used by
painters particularly for small pictures commonly called "artists sketching boards'
and its object is to increase the strength of such boards or reduce their liability to
split with the grain.
For this purpose I form said boards of three layers or thicknesses of any suitable
wood glued or otherwise cemented securely together with the grain or fibre of the
inner layer laid at right angles to the outer layers the grain of the latter being
placed parallel to each other.
By this construction an approximately uniform strength is obtained and any
tendency to twist or split is reduced to a minimum which particularly in the case of
a valuable picture is a matter of very great importance.
Dated this 8th day of February 1893.

COMPLETE SPECIFICATION.
Improvements in Sketching Boards used by Painters and the like.
I, ALFRED EDWARD RIGG, of 5, Victoria Terrace, Fagley Road, Eccleshill,
near Bradford, in the County of York, Fine Art Dealer, 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 the boards or wooden panels used by,
painters particularly for small pictures commonly called "artists sketching boards
and its object is to increase the strength of such boards or reduce their liability to
split with the grain.
For this purpose I form said boards of three layers or thicknesses of any suitable
wood glued or otherwise cemented securely together with the grain or fibre of the
inner layer laid at right angles to the outer layers the grain of the latter being
placed parallel to each other.
By this construction an approximately uniform strength is obtained and any
tendency to twist or split is reduced to a minimum which particularly in the case of
valuable pictures is a matter of very great importance.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification, in which
Figure 1, represents a sketching board made in accordance with my invention,
and. having the greater part of the upper layer of wood broken away to show the
central layer.
Figure 2, represents a cross section of a portion of the same on a larger
scale.
The outer layers of wood A, A are glued to the inner layer B with the length-
way of the grain or fibre of the latter approximately at right angles to the length-
way of the grain or fibre of the former. The central layer B may be made twice

page_text: as thick as the outer layers A, A so as to make the sketching board of fairly
uniform strength in either direction.
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 I
claim is:
An artist's sketching board formed of three' thicknesses or layers of wood and
having the length-way of the grain or fibre of the outer layers more or less-parallel
and disposed at approximately right angles to the grain or fibre of the inner or
central layer, substantially as herein shown and described.
Dated this 7th day of November 1893.
