AN IMPROVED. ROLL FOR SPINNING MACHINES
Year: 1872

page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine,
Lake, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of "AN IMPROVED. ROLL FOR SPINNING MACHINES."-A
communication from abroad by William A. Caswell, of Providence,
Rhode Island, United States of America.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 14th March 1872.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare
the nature of the said Invention for "AN IMPROVED ROLL FOR SPINNING
MACHINES," a communication, to be as follows:-
:-
This Invention consists in certain novel combinations of textile fabric,
cork, or its elastic equivalent, and leather, attached as a covering for the
roll. The foundation of textile fabric may consist of a layer of cotton

page_text: or other braid, wound spirally around the roll from end to end with the
edges of the fabric adjacent to each other, but not too close to prevent
the adhesive cement usually employed from entering the intervening
spaces. A layer of cork wood is cut in a thin sheet and applied after
the manner of leather by means of adhesive cement. The exterior or
surface clothing of leather suitable for the purpose is applied in the
usual manner. For fine work the drawing surface may be ground off
to render the periphery of the roller true and even, and also to remove
the semi-spongy exterior surface of the leather. The layer of textile
fabric being well secured to the metal serves as a medium for effecting
a practically perfect union of the cork with the said metal, while at the
same time it possesses elasticity to a slight degree. The value of the
cork layer consists in its durable elasticity, and therefore a layer of any
other substance of a correspondingly elastic character, which is as
capable of being as firmly united to the foundation and to the leather
would approximate thereto in practical value. A roll thus constructed
possesses a peculiarly valuable degree of elasticity which greatly con-
tributes to its general efficiency and durability.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 13th September 1872.
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 Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of March, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Robert Lake, Her
special licence, that I, the said William Robert Lake, my executors,
administrators, and assigns, or such others as I, the said William Robert
Lake, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great

page_text: The value of the cork layer consists in its durable elasticity and
therefore a layer of any other substance of a correspondingly elastic
character which is as capable of being as firmly united to the foundation
and to the leather would approximate thereto in practical value. A
roll thus constructed possesses a peculiarly valuable degree of elasticity
which greatly contributes to its general efficiency and durability.
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 I am aware that strips of cloth wound
spirally have heretofore been employed as a foundation for top rolls, and
also that it has been proposed to apply cord or twine in that manner. I
am also aware that cork and leather have been employed for covering
top rolls, but I am not aware that a textile fabric, cork, or its elastic
equivalent and leather have been used in the combination herein
described, I therefore claim. a top roller having a metallic interior, a
foundation of textile fabric, an intermediate layer of cork or other
similarly elastic material and an exterior covering of leather, substantially
as described.
In witness whereof, I, the said William Robert Lake, have hereunto
set my hand and seal, this Thirteenth day of September, in the
year of our Lord One thousand eight hundred and seventy-two.
-Witness,
CHAS. J. GOOCH.
