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 "IMPROVEMENTS IN MACHINERY FOR MANUFACTURING
COTTON AND
OTHER FIBROUS MATERIALS."-A communication from
abroad by John McDonald, of Concord, North Carolina, United
States of America.
Sealed the 4th March 1873, and dated the 11th September 1872.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition, on
the 11th September 1872.
FOR
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 "IMPROVEMENTS IN MACHINERY
MANUFACTURING COTTON AND OTHER FIBROUS MATERIALS," a communication,
to be as follows:-
This Invention consists in applying the slivers of cotton as they pass
from one pair of rollers to another in the several conveying and drawing

page_text: operations, collars having converging apertures resembling the section
of the sliver, which, by smoothing down any loose or projecting fibres
from becoming detached and resting tangentially against the surfaces of
the rollers burnishes them and prevents the sliver from adhering to
them and enables me to dispense with the process of varnishing the
rollers.
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 10th March 1873.
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 Eleventh day of September in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Robert Lake, Her special
licence that I, the said William Robert Lake, my executors, adminis-
trators, 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 thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN MACHINERY For ManufacturING COTTON AND OTHER FIBROUS MATERIALS," a
communication to me from abroad by John M Donald, of Concord,
North Carolina, United States of America, upon the condition
(amongst others) that I, the said William Robert Lake, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawing forming a part of this Specification :-
This Invention consists in applying to the slivers of cotton as they
pass from one pair of rollers to another in the several conveying and
drawing operations, collars having converging apertures resembling the
section of the sliver, and which, by smoothing down any loose or
projecting fibres, prevent their becoming detached and resting tan-
gentially against the surfaces of the rollers, burnishing them and
O preventing the adhesion of the sliver to them. I am thus enabled to
dispense with the process of varnishing the rollers.
DESCRIPTION OF THE DRAWING.
Fig. 1 is a plan; Figure 2 is a horizontal section on the plane indi-
cated by the line x, x, in Figure 3; Figure 3 is a vertical section in
the plane indicated by the line y, y, in Figure 1; and Figure 4 shews
the collar D drawn separately in elevation. The same letters of
reference indicate the same parts in the several Figures.
A represents a sliver of carded cotton; B and B are a pair of rollers
between which the sliver passes to a second pair of rollers B³ and B³
which move with greater velocity than the pair B and B¹.
D is a collar through which the sliver A slides in a converging
aperture E which compresses the sliver during the drawing process,
and smoothing any loose projecting fibres down to the body of the sliver
prevents thier loss; the sliver so compressed and smoothed does not
adhere to the leather covered rollers and wrap on them so readily as
when uncompressed by the collar D.
The rollers are burnished and kept clean and smooth by the collar D
resting tangentially and rubbing against them.
The collar D is preferably made of wood or other light material such
as horn, raw hide, or hard rubber, but may be of metal if desired. The
effects of using it are found to be a considerable saving of cotton, and
greater cleanliness of the mill, higher speeds can be used, and the
varnishing of the drawing rollers becomes unnecessary; besides which,
any hygrometric changes in the atmosphere do not affect the operation
of drawing frames constructed according to these improvements.

page_text: Having thus 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 do not claim the application of any con-
verging collar to slivers of fibrous material in course of preparation for
spinning; but I claim, the collars D, with converging apertures
applied to the slivers of cotton, or any fibrous material during the
process of extending the slivers between the carding and spinning
operations, the said collars resting tangentially against the roller faces.
and cleaning and burnishing them.
In witness whereof, I, the said William Robert Lake, have hereunto
set my hand and seal, this Tenth day of March, in the year
of our Lord One thousand eight hundred and seventy-three.
Witness,
JAMES EDWARDS,
