page_text: LETTERS PATENT to Henry Harris Lake of the firm of Haseltine Lake
and C° Patent Agents Southampton Buildings, London for an Invention of
"IMPROVEMENTS IN THE MANufacture of aRTIFICIAL IVORY" communicated
to him from abroad by Jarvis Boncsteel Edson, of Adams, Massachusetts,
United States of America
PROVISIONAL SPECIFICATION left by the said Henry Harris Lake at the
Office of the Commissioners of Patents on the 14th August 1883.
HENRY HARRIS LAKE of the firm of Haseltine Lake and Co. Patent Agents,
Southampton Buildings London "IMPROVEMENTS IN THE MANUFACTURE of
ARTIFICIAL IVORY" [a communication to him from abroad by Jarvis Bonesteel
Edson, of Adams, Massachusetts, United States' of America]
This invention relates to the Manufacture of Artificial Ivory from Xylonite or
a Cellulose Compound.
The object of the said invention is the production of an article which closely
resembles, and is adapted for use as a substitute for, ivory. The said invention
consists essentially in forming a composition chiefly of such substances as Xylonite,
or those elements which are formed chiefly of pyroxyline.
According to the present invention I form the Xylonite or its equivalent
substance, of different densities and in some cases of slight differences in color, and
cut the same into sheets, by any of the well known processes for such manufacture
and then combine them in the said sheet form, by rolling or pressing them together
under great pressure so as to compact the several sheets into one entire mass, but
in such a manner as to preserve the peculiar characteristics of the structure of each
sheet, and at the same time make such a compact body, that when it is cut into
thin sheets the various sections in the said sheets will show the different
characteristics or grain of the original sheets of which the mass was composed, and
thereby imitate the various growths or laminated character of the ivory.
It is evident that this composition and combination may be made of various
inaterials and in various manners without departing from the nature of this
invention.

HENRY HARRIS LAKE, of the firm of Haseltine, Lake and Co Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN THE MANUFACTURE OF
ARTIFICIAL IVORY." A communication to me from abroad by Jarvis Bonesteel

This invention relates to the manufacture of artificial ivory from xylonite or
a cellulose compound
The object of the said invention is the production of an article which closely
resembles, and is adapted for use as, a substitute for ivory
The said invention consists essentially in forming a composition chiefly of such
substances as xylonite, or those elements which are formed chiefly of pyroxyline.
According to tho present invention I form the xylonite or its equivalent
substance, of different densities and in some cases of slight differences in color and
cut the same into sheets, by any of the well known processes for such manufacture,
and then combine them in the said sheet form, by rolling or pressing them together
under great pressure so as to compact the several sheets into one entire mass, but
in such a manner as to preserve the peculiar characteristics of the structure of each-
sheet, and at the same time make such a compact body, that when cut into thin
sheets the various sections in the said sheets will show the different characteristics
or grain of the original sheets of which the mass was composed, and thereby imitate
the various growths or laminated character of the ivory.
It is evident that this composition and combination may be made of various
-materials and in various manners without departing from the nature of this
invention.
Having thus fully described the said invention as .communicated to me by my
foreign Correspondent and the manner of performing the same I wish it understood
that I claim :-
First. The method of forming artificial ivory or a substitute for ivory, by forming
the material for the several growths or layers of xylonite or similar substance of
different densities or different characteristics of composition; cutting the same into
sheets, and then compressing the several sheets of all the clements into one entire
mass; and making into sections the several layers as by the process of cutting, for
producing the sheets to imitate ivory as herein before set forth.
Second. An artificial ivory or substitute for ivory formed of xylonite or similar
compound, the basis of which is pyroxyline, so as to resemble ivory, substantially
as described.
In Witness whereof I the said Henry Harris Lake have hereunto set my hand
and seal this Thirteenth day of February in the year of Our Lord One thousand
oight hundred and eighty four.
