COMPLETE SPECIFICATION.
Artists' Painting Fabric or Material.
I, GUSTAV LANE, Painter, of Teplitz, in the Kingdom of Bohemia, do hereby declare
the nature of my said invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement :-
The invention hereinafter described refers to the production of a painting fabric or
material, being a board, panel, ground, or foundation, of wood, and has for its object to
do away with the- objections-which are particular to the foundations or grounds of
canvas or wood hitherto in use by artists and painters.
It is well known that in the art of Picture painting, generally canvas, or boards
made of different kinds of woods, have been used for the painting ground or
foundation; these foundations have defects which cause the destruction of many
valuable works of art.
The great defect of canvas foundations is the perishable nature of the material, and
further the changes which it undergoes in consequence of changes of temperature and
also the small resistance it offers to breakage by pressure or impact.
The defects of the painters' canvas which present themselves sooner or later, through
atinospheric influences, are noticeable in the innumerable small cracks and the netlike
craze, which after a time causes a scaling of the smaller particles. Canvas has the
further objection that it has to be stretched on a frame, which is provided at its four
corners with wedges to tighten the canvas, should it become slack.
This tightening of the wedges, which has to be resorted to with great frequency,
often results in the tearing asunder or separating of the colour particles, and in this
manner destroys the painting. Moreover the operation of stretching the canvas is
tiresome.
The painters' boards hitherto in use consist of a single thick wooden slab or panel,
and have the defects that they warp and crack even when very old and seasoned wood
is used, and even at times burst asunder; and finally become wormeaten; which
causes destruction or damaging of the picture.
The present invention, hereafter described, overcomes these defects, and a durable
fabric as a foundation or ground is provided.
According to this Invention, painting fabrics or foundations of any size are
constructed by glueing or cemeting, transversely or cross wise, under great pressure,
thin layers of suitable woods free from cracks. The number of the layers of wood
employed is at least three, but this can be increased at pleasure. In consequence
of the layers being glued together, cross-wise, and under a heavy pressure, they
become so firmly united that they cannot warp or bend in a dry or damp atmosphere,
nor do they crack or break in any way whatever. Moreover, destruction by action of
worms is prevented in consequence of the density of the material, and the layer of
glue or cement, which latter can be especially prepared by boiling with ingredients
such as Wermuth. In this manner the ground or foundation prepared by this
invention becomes imperishable and worm proof.
A particular advantage of constructing painting material or board as just described,
of three or more layers of wood, consists in its extreme lightness and elasticity, a
circumstance particularly advantageous for paintings of large dimensions.
Painters' fabrics or boards constructed according to this invention are 100 to 150%
cheaper than canvas stretched on frames, and about 300% cheaper than the massive
boards previously used.

page_text: 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
1. The herein described artists' painting fabric or material, that is to say, a fabric or
material composed of a plurality of layers of wood, arranged and glued or cemented
together transversely in the direction of their grain.
Dated this 3rd March 1890.
