Year: 1869

page_text: LETTERS PATENT to James Tolson, of Dalton, near Huddersfield,
in the County of York, Manufacturer, for the Invention of "AN
IMPROVEMENT IN OR APPLICABLE TO CERTAIN APPARATUS EMPLOYED FOR
CLEANING THE CARDS OF CARDING ENGINES OR MACHINES HAVING CYLINDERS
OR ROLLERS CLOTHED WITH CARDS."
Sealed the 2nd November 1869, and dated the 6th May 1869.
PROVISIONAL SPECIFICATION left by the said James Tolson at the
Office of the Commissioners of Patents, with his Petition, on the
6th May 1869.
I, JAMES TOLSON, of Dalton, near Huddersfield, in the County of
York, Manufacturer, do hereby declare the nature of the said Invention
for "AN IMPROVEMENT IN OR APPLICABLE TO CERTAIN APPARATUS EMPLOYED FOR
CLEANING THE CARDS OF CARDING ENGINES OR MACHINES HAVING CYLINDERS OR
ROLLERS CLOTHED WITH CARDS," to be as follows:-
This Invention relates to apparatus for which Provisional Protection;
was granted to me, dated January 30th, 1869, No. 299, the Specification.
of which gives an outline description of a comb cylinder for cleaning,.
and also gearing and racks for giving motion to the card cylinder or
rollers, and the present improvement consists in the application of a.

page_text: roller clothed or covered with either cards, felt, or some other material
of a soft, yeilding, or elastic nature, to be turned round by suitable
gearing from the power giving motion to the comb, cylinder, or other
cleaning apparatus, to rest or press upon and thereby communicate rotary
motion to the card cylinder or card roller of a carding engine to be
cleaned thereby. This roller may be either in contact with the cards
along the length of the card cylinder or card roller, or part of its length,
or (being proportionately conical where the diameter of the card cylinder
or card roller requires it) be applied so as to be in contact with and
revolve and press against the end or ends or part or parts of the
end or ends of the card cylinder or card roller to be turned round by
suitable gearing from the power giving motion of the comb cylinder or
other cleaning apparatus. By this Invention I avoid the costs of manu-
facturing and fixing the racks referred to in the aforesaid Provisional
Specification.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Tolson in the Great Scal Patent Office on
the 6th November 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
TOLSON, of Dalton, near Huddersfield, in the County of York, Manu-
facturer, send grecting.
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 sixty-ninc, in the thirty-
second year of Her reign, did for Herself, Her heirs and successors,
give and grant unto me, the said James Tolson, Her special licence
that I, the said James Tolson, my executors, administrators, and
assigns, or such others as I, the said James Tolson, 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 "AN IMPROVEMENT
IN OR APPLICABLE TO CERTAIN APPARATUS EMPLOYED FOR CLEANING THE CARDS
OF CARDING ENGINES OR MACHINES HAVING CYLINDERS OR ROLLERS CLOTHED WITH

page_text: CARDS," upon the condition (amongst others) that I, the said James
Tolson, my exccutors 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 James Tolson, 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 and accompanying Sheet of Drawings (that is
to say) :-
This Invention relates chiefly to apparatus for which Letters Patent
were granted to me, dated January Thirtieth, One thousand cight
hundred and sixty-nine, the Specification of which gives a description
of a comb cylinder for cleaning the cards of carding engines, and
also of gearing and racks for giving motion to the card cylinders or
rollers required to be cleaned thereby.
The present improvements consist in the application to the said or
other cleaning apparatus of a roller clothed or covered with either cards,
felt, or some other material of a soft, yielding, or elastic nature, the
said roller to be turned round by suitable gearing from the cleaning
apparatus or the power which gives motion to the comb cylinder (or
other cleaning apparatus), the said roller being caused to rest and press.
upon and by such contact communicate rotary motion to the card cylinder
or card roller of a carding engine required to be cleaned. This roller
may be either in contact with the cards along the whole length of the
card cylinder or card rollor or only a part of its length, or (being pro-
portionately conical where the diameter of the card cylinder or card
roller requires it) it may be applied so as to be in contact with and
revolve and press against the end or ends of the card cylinder or card
roller required to be turned round, motion being communicated thereto
by suitable gearing from the power which gives motion to the comb
cylinder or other cleaning apparatus.
This Invention will be readily understood by reference to the accom-
panying Drawings.
A represents (in outline) a comb cylinder as described in the Patent
referred to (or it may be some other cleaning apparatus applied in a

page_text: similar manner); B represents a card roller required to be cleaned; and
C represents the roller for communicating motion thereto from the comb
cylinder by means of the train of spur toothed gearing D, E, F, G, and H,
which are all mounted upon the arms I hinged on the axis of the comb
cylinder; K represents the surface of a card cylinder, which may be
cither the swift or the doffer of a carding engine, shewing that the same
apparatus is equally applicable to any diameter of cylinder or roller. It
will be obvious that the roller C by its contact with the points of the
card teeth will when motion is given to it turn the said card cylinder or
roller at the same surface speed, which is regulated by the gearing as
required according to the speed of the comb cylinder.
Having thus described the said Invention, and shewn by Drawings
how the same is or may be performed, I declare that I claim as of my
Invention the application and use in connection with apparatus for
cleaning the cards of carding engines of a roller covered with any suit-
able yielding material for driving or turning the said card cylinders or
rollers when under the operation of being cleaned.
In witness whereof, I, the said James Tolson, have hereunto set
my hand and seal, this Fourth day of November One thousand
cight hundred and sixty-nine.
Signed, sealed, and delivered by the
within-named James Tolson, in
the presence of
JOHN R. BROOKE,
Manufacturer,
Mold Green,
Huddersfield.
