IMPROVE- MENTS IN CARDING ENGINES
Year: 1873

page_text: LETTERS PATENT to Thomas Stone, of Preston, in the County of
Lancaster, Engineer and Machinist, for the Invention of "IMPROVE-
MENTS IN CARDING ENGINES."
Scaled the 11th July 1873, and dated the 20th January 1873.
PROVISIONAL SPECIFICATION left by the said Thomas Stone at the
Office of the Commissioners of Patents, with his Petition, on the
20th January 1878.
I, THOMAS STONE, of Preston, in the County of Lancaster, Engineer
5 and Machinist, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN CARDING ENGINES," to be as follows:-
.My Invention consists of certain improvements in carding engines,
whereby I dispense with the cylinder and some of the rollers, clearers.
and bends.

page_text: rollers on the same line, and behind such I place a carrying roller, and
again behind this the ordinary doffing cylinder comb and other apparatus
same as now in use. Underneath or in front of the second cleansing
roller I place a feed and dirt roller, with a self-stripping motion, which
is carried by a radial arm or otherwise from centre shaft of second roller. 5
A similar radial arm is fixed on the first clensing roller shaft of
sufficient length to carry a stripping roller on to the upper surface of the
second cleansing roller. I fix likewise on the third carrying roller shaft
a radial arm, carrying one or more working rollers on the upper side
of the carrying roller underneath the two clensing and the carrying ]
roller, I fix grates, if required by the quality of material used; I likewise
fix shields to the rollers to regulate the action of the atmosphere. By
this arrangement the cotton or other material is carried forward under
the first roller, retained by the second feed roller, carded and cleansed by
the second cleansing roller, carried from the dirt roller underneath the
second cleansing roller to the third or carrying roller, when it passes
upwards and underneath the working rollers, thence to the doffing
cylinder, from thence in the ordinary way finished.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Stone in the Great Scal Patent Office,
on the 19th July 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS 2
STONE, of Preston, in the County of Lancaster, Engineer and Machinist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of January, in the year
of our Lord One thousand eight hundred and seventy-three, in tho 3
thirty-fifth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Thomas Stone, Her special
licence that I, the said Thomas Stone, my executors, administrators,

page_text: when required by any particular kind of cotton I fix a dirt roller.
Underneath I fix ordinary grids when required.
I have now described the several parts of my Invention, and will now
proceed to describe its action on and treatment of the cotton.
The lap of cotton B passes between rollers C in the usual way, and the
taker-in roller D carries it, as indicated by the arrow, underneath to
roller E, between which rollers it is thoroughly opened. The cotton
then passes under small roller J, which is so arranged to allow the
opened cotton to pass, but to rotain the husk and motes and all
unopened lumps, which by the action of roller J are carried back to
taker in, thence underneath. The cotton passes on by roller E under
roller I, where it is straightened, thence to roller F. The centrifugal
force of roller E is such as to throw off the ends of fibre not held by the
wire on such roller, thus enabling roller F to take hold of the loose or
open end of the fibre and carry it forward to roller K, which again
straightens it. The cotton then passes onward to roller L, and thence to
doffing cylinder finished carding.
It will be observed that the cotton does not pass round roller F, but
that roller F takes hold of the loose end of the fibre and carries it
forward from roller E. The rollers N and M act as clearers to rollers I,
K, and L.
Having now described my Invention, and the way in which it is
worked, I wish it to be distinctly understood that I do not confino
myself to the precise details I have had occasion to describe and refer to,
as many variations may be made without deviating from the principle or
main features of this my Invention, as, for instance, in carding short
staple cotton I should not use rollers I, L, and M, but should use a dirt
roller in the space occupied by the letter O. I may likewise dispense
with any one or more rollers herein shewn and described to suit the
various kinds of cotton to be carded.
What I claim as secured to me herein is,―
First. The two carding rollers E and F, substantialy as and for the
purposes heroin set forth.
Second. The rollers and clearers I, J, K, L, M, N, and O, substantialy
as and for the purnosne kounin and Candle
