Gentleman, for an Invention of " TREATING AND TRANSMUTING WOOD AND
OSSEOUS MATERIALS INTO ARTICLES OF UTILITY."

PROVISIONAL SPECIFICATION left by the said William Boggett at the Office
of the Commissioners of Patents on the 14th February 1880.
WILLIAM BOGGETT, of Chelsea, in the County of Middlesex, Gentleman.
TREATING AND TRANSMUTING WOOD AND OSSEOUS MATERIALS INTO ARTICLES
OF UTILITY."
The object of this Invention is to transmute wood, bone, and ivory, into articles
of use and ornament by the following processes:-In the first place I reduce the
materials into fine powder by grinding or otherwise, and then soften it by boiling
in water to which (in some cases) mineral acid is added for the purpose of bringing
the powder into a state of pulp, in which condition paste or other adhesivo
ingredients are incorporated with it in proportions suitable for giving it the proper
consistence. The mixture is then placed in strong moulds plain or engraved with
ornamental devices, or otherwise, wherein the plastic mass is firmly consolidated
under great pressure into a plain block, or is impressed with the engraved or other
device. When the articles so produced are dry I in some cases render them wholly
or partially translucent by steeping them in diluted phosphoric acid.
Aniline or other dyes can be mixed with the pulp or be applied in any of the
subsequent stages of manufacture.

TREATING AND TRANSMUTING WOOD AND OSSEOUS MATERIALS INTO ARTICLES OF
UTILITY."
The object of my Invention is to treat chicap or refuse woody materials, likewise
portions of bone and ivory of small value, by the hereinafter described methods for
the purpose of transmuting them into articles of commercial value.
The woody materials above referred to consist of cocoa nut fibre, tanners' spent
bark, wood saw dust, shavings, turnings, chips, and other woody refuse, refuso cork,
the available woody parts of furzo, and gorse; also bamboo and other canes, either
of which may be treated separately or combined with any of the foregoing
articles.
In operating upon the above named materials in accordance with my improve-
ments I in general bring them into a finely divided state by, in the first place,
boiling and afterwards grinding them while moist, and with or without paste (in
the proportion of about one pound paste, more or less, or other adhesive materials to
five pounds of the raw material) in a suitable machine into pulp. The machine I
find it advantageous to employ consists of three rollers inade of granite which revolve
at unequal rates of speed, the intermediate roller having a to-and-fro lateral motion
as it revolves.
When ground the mass can be made to assume any desired form by being pressed
(by hydraulic or other means) in strong metal moulds with plungers and perforated
plates for the egress of water, as is well understood.
In some cases the pulp is conveyed to a board rolling machine, which is similar
in construction to a cardboard machine, but heavier. When made into a shect or
board it is carefully dried between layers of steam pipes.
The pressed articles or materials are made water-proof by immersing them in
boiled oil, the oil being then dried into the surfaco by exposure to heat of from 200
to 300 degrees Fahrenheit, according to the nature of the articles.
In some cases I make the pulp water-proof throughout by grinding the woody
materials along with the best boiled linseed oil, which requires no other adhesion,
and it is then pressed as before described.
One method of treating saw dust, according to my improvements, is to imbrown
it by heat, grind it to about the size of coffee grains and sift through fine wire
gauze; in this state it is fit to mix with adhesive inaterials and to be pressed.
Wood shavings and turnings when placed in a strong solution of sulphuric acid,
become partially dissolved; when the acid has been removed by washing, the pulpy
mass should be well dried, and then ground; canes may be advantageously treated
by like means. The canes are first crushed between rollers, then softened by
boiling, and after being split into strips or filaments are made ready for grinding
by being cut into small pieces by a chaff cutter or other suitable machine.
My Invention further embraces the application of like processes for the conversion
of osseous materials (bone and ivory) into articles of utility. In treating them I
first reduce them to powder, with which I incorporate rye flour paste or other
adhesive materials and grind them to a proper consistence between rollers in the
aforesaid mill to be compressed in moulds, as before described.
Aniline or other dyes may be added to the osseous pulp or applied to any of the
finished articles.
Having thus described the nature of my Invention, and the best manner known
to me of carrying it into practice, I would romark that I do not claim separately

page_text: any part or parts of the processes or machinery herein beforo described, which are
well known and in common use, but what I claim is,-
The several improved methods hereinbefore described of treating the above
enumerated woody and osseous materials for the purpose of converting them into
vendible productions, substantially as herein described.
In witness whereof, I, the said William Boggett, have hereunto set my band
and seal, this Twelfth day of August, in the year of our Lord One thousand
eight hundred and eighty.
WILLIAM BOGGETT. (L.S.)
