CERTAIN IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON AND OTHER FIBRES.”
Year: 1874

page_text: LETTERS PATENT to Thomas Henry Rushton, of the Firm of Messieurs
Dobson and Barlow, of Bolton, in the County of Lancaster, Machine
Maker, for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY
FOR PREPARING COTTON AND OTHER FIBRES.”

page_text: In performing my Invention I place six or other convenient number
of drawing heads side by side. The slivers for supplying the drawing
rollers are drawn out of cans or unwound off narrow rollers. In front
of the drawing heads is a table, and between each front drawing roller
and the table is a broad curved plate on which the sliver is guided to
the table. At the end of the table is a pair of lap rollers. When the
machine is at work, the broad slivers issuing from the drawing rollers
are laid one over the other on the table, and are all wound together on
the lap roller. I place two or more pairs of calendar rollers on the
table to consolidate the slivers bofore they are wound into a lap.
The laps so prepared are particularly useful when taken to the
combing machine, as the fibres are distributed evenly on the face of the
lap, and do not injure the combs. The laps may however be otherwise
disposed of.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 1
filed by the said Thomas Henry Rushton in the Great Seal Patent
Office on the 4th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
HENRY RUSHTON, of the Firm of Messieurs Dobson and Barlow, of
Bolton, in the County of Lancaster, Machine Maker, send greeting. 2
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of May, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Thomas Henry Rushton, Her special licence that
I, the said Thomas Henry Rushton, my executors, administrators, and
assigns, or such others as I, the said Thomas Henry Rushton, 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.

page_text: "CERTAIN IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON AND OTHER
FIBRES," upon the condition (amongst others) that I, the said Thomas
Henry Rushton, 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 Thomas Henry Rushton, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement (that is to say) :-
My Invention is applicable. to the machines known as drawing frames,
and it consists in an improved mode of collecting the fleeces from any
convenient number of drawing heads and forming them into a lap.
In drawing frames of the usual construction the fleece from each
drawing head is carried through a trumpet mouth to contract it into a
sliver, and these slivers are laid side by side on a table before they are.
formed into a lap. The action of these trumpet mouths is objectionable,
as the fibres at the edges of the fleece are turned over, and when such
laps are taken to the comber they are liable to injure the teeth of the
combs.
In performing my Invention I place six or other convenient number
of drawing heads side by side. The slivers for supplying the drawing
rollers are drawn out of cans or unwound off narrow rollers. In front
of the drawing heads is a table, and between each front drawing roller
and the table is a broad curved plate on which the sliver is guided to.
the table. At the end of the table is a pair of lap rollers. When the
machine is at work the broad slivers issuing from the drawing rollers,
are laid one over the other on the table, and are all wound together on
the lap roller. I place two or more pairs of calender rollers on the table
to consolidate the slivers before they are wound into a lap.
And in order that my Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked,
thereon.

lescribed.
In witness whereof, I, the said Thomas Henry Rushton, have hereto
set my hand and seal, this Third day of November, One thousand
eight hundred and seventy-four.
THOMAS HENRY RUSHTON. (L.S.)
