Improvements in Ornamenting Wooden Surfaces.
I, WALTER MARTENE TAYLOR of 36 Great Percy Street, in the County of
London, Mechanical Engineer do hereby declare the nature of this invention to be
as follows:
This invention for improvements in ornamenting wooden surfaces has for its
object to reproduce, by a mechanical and chemical process without the aid of
skilled labour, ornamental designs on wooden surfaces; and consists essentially in
applying in a dark room to the surface to be treated a solution of nitrate of silver
or other similar salt, in covering the said surface with a stencil transparent design
photographic plate or other pattern, in then exposing the said surface to the action
of light for a certain time depending on the power of the light and the darkness of
tint of pattern desired, and in finally removing or neutralizing the action of the
said salt not affected by the exposure. It will readily be seen that any desired
number of copies of the design can be produced from one stencil or one pattern.
The surface may be toned or coloured in the usual manner as practised in
photography.

COMPLETE SPECIFICATION.
Improvements in Ornamenting Wooden Surfaces.
I, WALTER MARTENE TAYLOR, of 36 Great Percy Street, in the County of
London, 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 for improvements in ornamenting wooden surfaces has for its
object to reproduce ornamental designs on wooden surfaces by a mechanical and
chemical process without the aid of skilled labour; and consists essentially in
producing the appearance of inlaid work on wooden surfaces by a sun or light
printing process.
In one process for carrying out this invention, the wooden surface to be treated
is made as smooth as possible in the usual manner including preferably damping
with warm water, drying and then sand papering to prevent the fibres rising during
the printing process. It is then thoroughly sized to fill all the pores of the wood
dried and thinly coated with a suitable solution of albumen. The size should be
sufficiently thick to prevent the nitric acid of the nitrate of silver to be next applied
from staining the wood. When the albumen is dry a sensitizing solution such as
nitrate of silver is applied for a sufficient length of time to properly scusitize the
albumen surface.
The designs to be printed on the above described sensitized surface are painted,
lithographed, printed or otherwise produced on thin sheets of transparent material
such as gelatine or celluloid. The sheet having the desired design on it is
placed on the prepared surface of the wood and it is then exposed until the
exposed parts have attained the desired depth of colour or shading. The exposed
surface is then treated or immersed for a few minutes in an alkaline solution
CO

page_text: such as
common salt washed and treated with a neutralizing solution such as
hy posulphite of soda, for a sufficient length of time and allowed to dry without
washing. Preferably the sensitized wooden surface should be exposed within
3 days of being sensitized.
In order to colour the light parts of the design so produced, transparent colours
are applied with a brush or in other suitable manner and as these colours are
practically invisible on the darkened surface and the shading is effected in the
original design and reproduced by the sun printing process they can be cheaply
and expeditiously applied without skilled work.
The surface is then finished in the ordinary way by varnishing or polishing.
The process for ornamenting wooden surfaces may be modified in various ways
without departing from the nature of this invention as with obvious modifications
any of the known sun or light printing processes are applicable.
This process is also applicable for producing descriptive window tickets of wood,
or wooden name tablets.
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 process for ornamenting wooden surfaces consisting essentially in pro-
ducing the appearance of inlaid work on wooden surfaces by a sun or light printing
process.
2. The improved process for ornamenting wooden surfaces substantially as
described.
