COMPLETE SPECIFICATION filed by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 7th June 1875, pursuant to the 9th Section

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED
MANUFACTURE CONSISTING IN THE PRODUCTION OF LEATHER PULP, AND THE UTILI-

page_text: ZATION OF THE SAME FOR THE MAKING OF ARTICLES USUALLY FORMED BY MOULDING
OR COMPRESSION," and have petitioned Her Majesty to grant unto me,
my executors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn Declaration that it has been com-
municated to me from abroad by Benjamin James, of Worcester, 5
Massachusetts, United States of America.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed, in and by the 1
following statement:-
This Invention relates to leather pulp to be employed in the produc-
tion of all articles or objects that can be formed by moulding or com-
pression in dies or moulds.
"
In the preparation of this material according to my Invention, all 1
portions of the hide may be employed, including the "skivings or
"jumpings" of sole leather, the pulp produced from the latter being of
peculiar excellence.
The leather or hide is first ground, macerated, or otherwise reduced to
a powder, or to a condition of proper fineness, and then mingled with 2
water, bringing the mass to a proper degree of consistency.
The requisite amount of the material dampened as aforesaid is placed
in a mould or die of suitable shape to produce the desired article, and is
subjected to pressure. The article thus formed is then removed from
the die or mould and dried, when it may be used as desired, or if 2
preferred, it may be lacquered, varnished, or japanned.
If great tenacity is required some adhesive matter may be mixed with
the pulp either with or without the addition of water.
If the article is to be used in a position where it may be exposed
to much dampness, an insoluble cement may be employed to advantage. 3
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. Leather pulp suitable for use in the production of articles
formable by compression or moulding..
3

page_text: Second. The utilization of the said leather pulp for the production of
any article or object formed by moulding or compressing the same in
moulds or dies as herein set forth.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this Seventh day of June, in
year of our Lord One thousand eight hundred and seventy-
the'
five.
Witness,
HY. JA. NOONE.
