AN IMPROVEMENT OR IMPROVE- MENTS IN THE PROCESS OF CARDING WOOL, COTTON, SILK, OR OTHER FIBROUS MATERIALS, AND IN MACHINERY OR APPARATUS APPLICABLE FOR THAT PURPOSE
Year: 1861

page_text: LETTERS PATENT to George Hulme, of Rochdale, in the County of
Lancaster, Machinist, for the Invention of "AN IMPROVEMENT OR IMPROVE-
MENTS IN THE PROCESS OF CARDING WOOL, COTTON, SILK, OR OTHER FIBROUS
MATERIALS, AND IN MACHINERY OR APPARATUS APPLICABLE FOR THAT
PURPOSE."
Sealed the 24th October 1861, and dated the 30th April 1861.
PROVISIONAL SPECIFICATION left by the said George Hulme at tho
Office of the Commissioners of Patents, with his Petition, on the 30th
April 1861.
I, GEORGE HULME, of Rochdale, in the County of Lancaster, Machinist, do
hereby declare the nature of the said Invention for "AN IMPROVEMENT OR
IMPROVEMENTS IN THE PROCESS OF CARDING WOOL, COTTON, SILK, OR OTHER FIBROUS
MATERIALS, AND IN MACHINERY OR APPARATUS APPLICABLE FOR THAT PURPOSE," to
be as follows:
The object of my said Invention is to ensure uniform length of lap in the
picting of rolls, slivers, or cardings of wool or other materials after the same
have been doffed from the carding engine. In piecing apparatus, as usually
constructed, the length by which one set of rolls or cardings is allowed to
overlap the ends of the preceding set to which they are to be pieced, is liable
to irregularity through variation in the relative speed of the creeper or flexible
travelling apron, by which the rolls or cardings are conveyed to the rubbers

page_text: or tubes, as compared with that of the chain of buckets, which receives the
said rolls or cardings from the engine, and deposits them upon the creeper.
My Invention consists in imparting certainty and regularity to the motion
of the creeper by making a positive connection between it and its driving
roller by means of interlocking projections and depressions, pins, teeth, or other
mechanical means, instead of allowing it, as heretofore, to be dependant for
its motion upon the friction or adhesion of contact between its surface and
that of the said roller. By this arrangement the driving roller of the creeper
and that of the bucket chain being mutually in gear, the creeper and buckets
must necessarily move in unison and maintain the same relative positions
without either getting unduly in advance or in arrear of the other.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Hulme in the Great Seal Patent Office on the 30th
October 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HULME, of Rochdale, in the County of Lancaster, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of April, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said George Hulme, Her special licence that I, the said George Hulme,
my executors, administrators, and assigns, or such others as I, the said
George Hulme, 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
OR IMPROVEMENTS IN THE PROCESS OF CARDING WOOL, COTTON, SILK, OR OTHER
FIBROUS MATERIALS, AND IN MACHINERY OR APPARATUS APPLICABLE FOR THAT
PURPOSE," upon the condition (amongst others) that I, the said George
Hulme, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and scals, 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..

page_text: NOW KNOW YE, that I, the said George Hulme, 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:-
The object of my said Invention is to ensure uniform length of lap in the
piecing of rolls, slivers, or cardings of wool or other materials after the same.
have been doffed from the carding engine. In piecing apparatus, as usually
constructed, the length by which one set of rolls or cardings is allowed to
overlap the ends of the preceding set to which they are to be pieced, is liable.
to irregularity through variation in the relative speed of the creeper or flexible
travelling apron, by which the rolls or cardings are conveyed to the rubbers or
tubes, as compared with that of the chain of buckets, which receives the said
rolls or cardings from the engine, and deposits them upon the creeper.
My Invention consists in imparting certainty and regularity to the motion
of the creeper by making a positive connection between it and its driving
roller by means of interlocking projections and depressions, pins, teeth, or
other mechanical means, instead of allowing it, as heretofore, to be dependent
for its motion upon the friction or adhesion of contact between its surface and
that of the said roller. By this arrangement the driving roller of the creeper
and that of the bucket chain being mutually in gear, the creeper and buckets
must necessarily move in unison and maintain the same relative positions
without either getting unduly in advance or in arrear of the other.
This Invention will be clearly understood by referring to the figures and
letters on the accompanying Sheet of Drawings, in which Fig. 1 is an end
elevation of part of an ordinary carding engine and piecing apparatus having
one of my improved modes of giving a positive motion to the creeper,
and Fig. 2 an end elevation of one of the parts drawn about full size.
In Fig. 1, a represents part of the framework of the piecing apparatus ; b,
the buckets; c, the pulleys which guide them; d, the creeper; and c, the
rubbers. Instead of a plain roller for giving motion to the creeper, I employ
one having at each end recesses or indentations at suitable distances apart,
and place at similar distances projections or teeth on the straps attached to the
creeper, by which means the creeper receives a positive motion.
atf;
In Figs. 1 and 2 one of the rollers for giving motion to the creeper is shewn
it has recesses g, which receive the projections h on the straps i, to which
the bars of the creeper are fixed. It is evident that as the roller turns the
projections on the straps fit into the recesses of the roller, and cause the
creeper to move with certainty.
The number of recesses and projections, and also their shapes, may be varied

page_text: as desired, and the rollers may be formed with pins or teeth, and the creeper
attached to straps or chains having corresponding recesses.
Having now described the nature and particulars of my said Invention, and
the manner in which the same is to be performed, I desire it to be understood
that I claim in the process of carding wool, cotton, silk, or other fibrous
materials, the imparting certainty and regularity to the motion of the creeper
by making a positive connection between it and its driving roller by means of
interlocking projections and depressions, pins or teeth, as such improvements
are herein described, and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said George Hulme, have hereunto set my
hand and seal, this Twenty-ninth day of October, in the year of our
Lord One thousand eight hundred and sixty-one.
Signed, sealed, and delivered by the
within-named George Hulme, in
the presence of
GEORGE HULME. (L.S.)
