IMPROVEMENTS IN THE CONSTRUCTION OF , CARDING ENGINES
Year: 1877

page_text: LETTERS PATENT to James Edward Worsley, of Haslingden, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF
, CARDING ENGINES."
Sealed the 18th May 1877, and dated the 23rd March 1877.
PROVISIONAL SPECIFICATION left by the said James Edward Worsley at
the Office of the Commissioners of Patents on the 23rd March 1877.
JAMES EDWARD WORSLEY, of Haslingden, in the County of Lancaster.
PROVEMENTS IN THE CONSTRUCTION OF CARDING ENGINES.'
"IM-
This Invention is designed principally to be applied to carding engines employed
for carding cotton waste, but it may also be adapted to carding engines used for
carding other fibrous substances.
•
The object of the Invention is to prevent the fleece or sliver, as it is delivered by
the doffing comb, from adhering to the sides of the draw box as it passes onwards
to the trumpet or condensing rollers, whereby the fleece or aliver frequently becomes
torn or broken, and imperfect work results. For this purpose, instead of making
the draw box (or sloping trough, down which the fleece or sliver passes) with
straight sides gradually sloping inwards as heretofore, I make the sides of a rounded
form, curving inwards towards the centre, and at or near the top (and close to where
the sliver or fleece is delivered by the doffing comb) I place at each side a small
tube, the end of which is open and is directed inwards. These tubes are connected
to a fan or other convenient blowing apparatus, and the consequence is, that as the
sliver or fleece is delivered from the doffer it is blown inwards towards the centre,
so that its edges do not touch the sides of the draw box or trough, and it passes
down the centre of the draw box in a more compact and even sliver than heretofore,
and is not so likely to become torn or injured as hitherto.

IM-
This Invention is designed principally to be applied to carding engines employed
for carding cotton waste, but it may also be adapted to carding engines used for
carding other fibrous substances.
The object of the Invention is to prevent the fleece or sliver, as it is delivered by
the doffing comb, from adhering to the sides of the draw box as it passes onwards
to the trumpet or condensing rollers, whereby the fleece or sliver.frequently becomes
torn or broken, and imperfect work results. For this purpose, instead of making
the draw box (or sloping trough, down which the fleece or sliver passes) with
straight sides, gradually sloping inwards as heretofore, I make the sides of a rounded
form, curving inwards towards the centre, and at or near the top (and close to where
the sliver or fleece is delivered by the doffing comb) I place at each side a small
tube, the end of which is open and is directed inward. These tubes are connected
to a fan or other convenient blowing apparatus, and the consequence is, that as the
sliver or fleece is delivered from the doffer it is blown inwards towards the centre,"
'so that its edges do not touch the sides of the draw box or trough, and it passes
down the centro of the draw box in a more compact and even sliver than heretofore,
and is not so likely to become torn or injured as hitherto.
The method of carrying my Invention into practical effect will be readily under-
stood on reference to the annexed Drawing and to the following explanation
thereof.
The Drawing represents a face view of part of the delivery end of a carding
engine with my improvements shown as applied thereto, a, a, being part of the
framing; b, b, the dofting cylinder; and c, c, the doffing comb; d, d, is the draw box or
sloping trough, the sides of which instead of being straight as usual, are curved inwards
towards the centro, as shown at e, e; ff, are the air tubes (one at each side) which
are connected to a fan or other convenient blowing apparatus, and their upper ends
are open and directed inwards, so as to act on the edges of the fleece as it is de-
livered from the doffing comb and blow the fleece inwards towards the centre, so
that its edges do not touch the sides of the draw box, as herein-before explained.
These tubes are provided with taps g, g, to regulate the current of air as required.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I wish it to be understood that I claim as my Invention,
Firstly. The peculiar form and construction of the draw box with the sides curved
inwards, as herein-before described.
And, Secondly. I claim the use and application of a current of air at each side,
close to where the sliver is delivered, for the purpose of preventing the edges thereof
from coming into contact with the sides of the draw box, substantially as herein-
before described and illustrated by the Drawings annexed.
In witness whereof, I, the said James Edward Worsley, have hereunto set
my hand and seal, this Twenty-first day of September, in the year of
our Lord One thousand eight hundred and seventy-seven.
