page_text: LETTERS PATENT to William Gawthorp, John Reddihough, Woolcombers
and Samuel Wade, Overlooker all of Bradford in the County of York for an
Invention of "IMPROVEMENTS IN CARDING MACHINES"
PROVISIONAL SPECIFICATION left by the said William Gawthorp, John
Reddihough, and Samuel Wade at the Office of the Commissioners of Patents
on the 14th December 1883.
WILLIAM, GAWTHORP, JOHN REDDIHOUGH, Wool Combers, and SAMUEL WADE,
Overlooker, all of Bradford in the County of York IMPROVEMENTS IN CARDING
MACHINES
:
The object of this invention is to effect certain improvements in carding Engines
whereby the wool is more effectually carded giving more top and less noil and
therefore less card waste.

In carding machines as they are usually constructed, rollers known as workers
having carding surfaces are applied to the main card cylinder making contact
therewith. In order to extend the contact surfaces, attempts have been made to
substitute for the worker rollers a sheet of card passed round two rollers as
described in the specification of Armitage Haigh and George Milnes numbered 2814
A.D. 1879, but the method as described in the above cited specification has not
been found to be practically useful.
Our invention consists in passing around the rollers and doffers, strips of card
clothing side by side, of the required number and breadth to suit the width of the
card cylinder. These strips are separate and not made into a sheet as described in
Haigh and Milnes specification. In the working of this our improvement we find
the staple of the wool is taken by the end or point and thus passed on from end to
end of the machine thereby preventing the looping and breaking of the fibre as is
the case in the general mode of carding at the present time.
The smoothness with which the wool is passed from card to card insures a saving
in the cost of card clothing.
In cases where the wool is not difficult to card, the carding machine may, by the
adoption of our improvement, be shortened by nearly one half, thus economising in
the cost of the machine and also in space for the machine.

WILLIAM GAWTHORP, JOHN REDDIHOUGH, Wool Combers, and SAMUEL WADE,
Overlooker all of Bradford in the County of York. IMPROVEMENTS IN CARDING
MACHINES
The object of this invention is to effect certain improvements in Carding engines,
whereby the fibre that is being operated upon is more effectually carded, giving
more top and less "noil" and therefore less card waste.
In carding machines as they are usually constructed, rollers known as "workers"
having carding surfaces, are applied to the main card cylinder making contact
therewith. In order to extend the contact surfaces, attempts have been made to
substitute for the "worker rollers" a sheet of card passed round two rollers as
described in the specification of Armitage Haigh and George Milnes numbered 2814
A.D. 1879, but the method as described in the above cited specification has not
been found to be practically useful.
Our invention consists in passing around the rollers and doffers, strips of card
clothing, side by side of the required number and breadth to suit the width of the
card cylinder. These strips are separate, not made into a sheet as described in the
specification of Haigh and Milnes. In the working of this our improvement, we
find the staple of the wool is taken by the end or point of the card teeth, and thus
passed on from end to end of the machine, thereby preventing the looping and
breaking of the fibre, as is the case in the general mode of carding at the present
time, and the smoothness with which the wool is passed from card to card, insures
a saving in the cost of card clothing.
In cases where the wool is not difficult to card, the machine may by the adaption
of our improvement be shortened by nearly one half, thus economising in the cost
of the machine, and also in space for the same.
The accompanying drawing represents the side elevation of such portions of a
carding engine as are required to explain the application of our improvement.
The framework A, the cylinders commonly termed the lickers in B, fly C,
fancy D, and stripper rollers E, are of the ordinary construction, and receive motion
in the usual manner.
In lieu of the ordinary "worker rollers," we substitute the rollers F, and G,
which are mounted in suitable journals H, of the ordinary construction; and
rotated by chains in the same manner as ordinary "worker rollers." Around the
rollers F, and G, we place endless sheets of carding cloth J, which are composed of
a series of narrow endless strips, and caused to rotate in the manner as before
described. In contact with each endless sheet as above constructed, we place a
surface plate K, extending the full width of the machine, or a small roller may
be used for the purpose, the regulation of which by the nuts on stud P, adjusts
the sheet of card cloth J so as to be more or less in contact with the fly cylinder C
By the use of endless carding sheets J, constructed in the manner described, we
obtain considerably more surface in contact with the fly cylinder C, than can be
obtained by the ordinary "worker rollers," the circumferences of which only come
in contact, but by our arrangement the carding sheets J are for a considerable
distance in contact with the circumference of the fly cylinder C, consequently the
fibre is subjected for a longer period to the teeth of the fly cylinder C, thereby
opening out the knotty parts more effectually, making the fibre straighter, thereby
producing more "top' or straightened fibre and less "noil" than can be
accomplished by machines of the ordinary construction

page_text: The foregoing part of the specification describes the improvement as applied in
lieu of the worker rollers only, but we wish it to be understood that the same
remarks apply also to the rollers R, and S, which are substituted for the doffing
cylinders
What we claim as our invention is :-
The combination of the surface plate K, or roller equivalent with endless carding
sheets J constructed substantially in the manner and for the purpose as herein before
described.
"
The use of endless narrow strips of carding cloth J mounted on the respective
rollers F and G, and R and S for the full width of the cylinders C, in lieu of the
ordinary "worker rollers" and
'doffing cylinders" substantially in the manner
and for the purpose as hereinbefore described and as illustrated by the accompanying
drawing.
In witness whereof I the said William Gawthorp for and on behalf of myself
and the said John Reddihough and Samuel Wade have hereunto set my hand and
seal this twelfth day of June in the year of our Lord One thousand eight hundred
and eighty four.
WILLIAM GAWTHORP. (L.S.)
