page_text: I, HERBERT JOHN HADDAN of 67, Strand, in the County of Middlesex; Civil
Engineer, do hereby declare the nature of this invention, a communication to me
from abroad by Charles Waterman Spurr, of 76 State Street, Boston, United
States, 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 improvement in veneering and is represented in the
accompanying drawings, of which Figures 1 2 and 3 indicate transverse sections
of veneering made in accordance with my invention.
Fig. 1 exhibits the veneer as plain, or not moulded or embossed, while in Fig. 2
it is shown as moulded or embossed. Fig. 3 represents it as moulded and having
the interstices of its backing filled as hereinafter described.
The said veneering is composed of sheets or veneers, of thin wood, laid in pack
and united by vulcanized rubber, in very thin sheets extending between them;
there being fixed to one of the outermost veneers, by vulcanised rubber or rubber
cement, a backing of card board, cloth or other suitable material.
In the said drawing a and c denote two thin wood veneers, 6 the vulcanized
rubber connecting them, while e is the backing and d the vulcanised rubber joining
such backing to the veneer c.
I do not confine my invention to two wood veneers only, as three or more
may be used in pack and connected by vulcanised rubber arranged between their
next adjacent surfaces and upon the surface to which the backing is fixed by such
rubber.
In manufacturing the veneering or combination described, I first use between
the surfaces to be connected a vulcanizable rubber or cement, and after having
spread it on such surfaces, or properly applied it thereto, and laid the whole
together in pack, I expose the pack to heat or a temperature such as will vulcanize
the rubber or cement.
The grain of one veneer I generally extend across that of the next one to it, in
order to strengthen them, so as to prevent them from cracking, under the high
temperature to which they may be subjected in the vulcanizing process,

page_text: Prior to subjecting the pack to such process I generally press it in a suitable
mould or moulds, or between dies, to impart to it any desirable ornamental
appearance, in some cases causing it to be more or less convex on the outer face
and correspondingly concave on the inner face of the pack. The said pack having
thus been moulded, embossed or ornamented, is to be heated to the proper
temperature for vulcanizing the rubber or rubber cement. The article or new
manufacture thus produced, will not only be very pliable, but water proof, so that
it can be fixed, by glue or cement to a surface to be veneered, without danger of
the glue, or moisture therefrom, striking through the veneers and staining or
otherwise injuring the outer surface of the outermost one.
In some cases I fill the interstices in the backing, as shown at f in Fig. 3 with
some suitable material, as filaments of cotton for instance, glued or cemented
together and to the backing, in order to impart to it, on its rear face, a plane-flat
surface.
Th veneering thus produced can be employed to great advantage in finishing
and ornamenting walls or furniture.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is:
1.) As a new or improved manufacture, veneering substantially as described,
consisting of thin veneers of wood, arranged in pack and connected by vulcanized
cement or india rubber, arranged between them; essentially as set forth.
2.) Veneering consisting of thin veneers of wood and a backing of other material
arranged in pack, and connected by vulcanized cement or india rubber, extending
between their next contiguous surfaces as set forth.
3.) Veneering substantially as described, moulded or embossed as specified and
consisting of thin veneers of wood, or such and a backing of the same or other
material, arranged in pack and connected by vulcanized cement or india rubber,
extending between their next contiguous surfaces as set forth.
4.) Veneering substantially as described, moulded as specified, and consisting
not only of thin veneers of wood, or such and a backing arranged in pack and
connected by vulcanised cement or rubber, extending between their next con-
tiguous surfaces, but of an auxiliary backing or fillings, essentially as described,
inserted in the cavities or interstices, of the primary backing, essentially as
explained.
