After the stenciling sheet has been applied and
the stenciling sheet cut and surplus portions
20 thereof removed, as shown in Figure 7, the plank
with the letters or other characters of stenciling
material adhering to it is subjected to the action
of a sandbiast operating under a pressure of ap
may be easily read as the letters standout very
distinctly against the dark background which is
apparently weather-beaten wood. It should also
be noted that as a large portion of the soft grain
has been removed by the sand blasting, the
weight of the sign will be greatly reduced and it
may be suspended from a light-weight support.
As a large part of the soft grain has been re
moved and the coating of varnish stain and ba
nana oil penetrates deeply into the hard grain
and remaining portion of the soft, grain, this
sign will stand exposure to weather as an out:

and the like.
While the sign illustrated in the drawing has

but the sand which strikes other portions of the
plank cuts through the wax and shellac and into
the wood from which the sign is made. The soft
30 layers of grain will be out faster than the layers
of hard grain and, therefore, the layers of hard
grain, which are indicated by the numeral 6, will
project outwardly from the layers of soft grain,
as shown in Figures 1, 2, and-3 and thus produce
35 a weather-beaten appearance.
After the sand?
blasting has been completed, the plank with the
stencil letters still adhering thereto is immersed
in a tank ‘I ?lled with a mixture of varnish stain
and banana oil. This mixture, which is indicated
by the numeral 8, is of such a depth that the en
tire plank may be immersed therein and should
consist of one-third banana oil and two-thirds
varnish stain. The varnish stain and banana‘
oil is absorbed by the wood from which the sign
is formed thus acting. as a preservative for the
wood and also imparting a desired color to the
derstood that the grain may run parallel to the
faces to be sand blasted, the latter arrangement
not being practical when soft wood is used but
producing a very beautiful effect when the plank 30
is cut from hard wood such as oak, maple or
“ ash. It will also be understood that any kind of
wood may be used and that the choice of grain
and the direction in which it runs is unrestricted.
Having thus described the invention, what is 35
claimed as new is:
_.The method of forming a sign consisting of
cutting a plank a predetermined length and width
and smoothing faces of the plank, applying suc
cessive coats of shellac to the plank to provide 40
smooth and highly polished surfaces for the plank
