Improvements relating to the Finishing of Wood Veneers.
I, HERBERT JOHN HADDAN, of the Firm of Herbert Haddan and Co., of
18 Buckingham Street, Strand, W.C., London, Civil Engineer, do hereby
declare the nature of this invention a communication to me from abroad by
Charles B. Judd, of Grand Rapids, County of Kent and State of Michigan,
United States of America, Manufacturer, 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 a certain new and useful process for finishing wood
veneers and consists in applying the finish or stain to the side of the veneer
which is attached to the stock, and drawing the same through the pores of the
wood to the exposed side, or surface of the veneer, with the natural grain of the
wood uninjured.
And the objects of the invention are, first, to preserve intact the natural grain
and texture of the wood; second, to provide a finish which cannot be injured by wear;
and, third, to produce a veneer finish which will at all times retain its colour and
texture, and which, in case of injury, can be refinished so as to present its original
appearance. These objects are accomplished by means of a process hereinafter
described.
The process consists in applying a staining or filling material to the under side
of the veneer, or to that side of the veneer which is to be attached to the stock or
object to be covered by the veneer, and then attach the veneer, so prepared, by
means of glue or cement, to the body by means of pressure necessarily used in
making the attachment of veneers; said pressure forcing the stain or filling into
the pores of the wood of the veneer, bringing out or emphasizing, as it were, the grain
The stain or filling may be

applied direct to the under side of the veneer, and the glue may be spread either
upon the veneer or upon the stock, as found most convenient; or, instead of
placing the stain or filling material upon the veneer directly, it may be placed in
the glue or cement and then the veneer attached by pressure in the ordinary
manner.
The pressure necessary to make the glue joint or veneer attachment, forces the
filling or colouring material into the pores of the veneer, completely filling the
game.
By this process the veneer will always retain its colour, and as the colour is
applied upon the under side and is pressed through the veneer, the exposed side of
the veneer covering can be varnished and refinished at any time in case it becomes
marred or injured.
The veneer can thus be stained in any colour or shade to suit the taste or fancy
of the users of this process.
In finishing wood veneers in the ordinary manner, by staining or otherwise, or
subjecting the exposed side to any composition, the grain of the wood is more or
less injured and the finish is easily marred or injured by wear.
By my process the finishing or filling being done upon the unexposed side of the
veneer, it entirely fills the pores of the wood and the exposed surface can thus be
finished in any well known method of finishing and can be refinished from time to
time, as long as any portion of the body of the veneer remains.

invention and in what manner the same is to be performed, I declare that what I
claim is :-

material into and through the pores of the veneer to the exposed surface,
substantially as described.
