Year: 1878

page_text: LETTERS PATENT to William Bryden and John William Wilkinson, both of
Morley, near Leeds, in the County of York, for the Invention of "IMPROVE-
MENTS IN SCRIBBLING AND CARDING MACHINERY."
Sealed the 6th May 1879, and dated the 12th November 1878.
PROVISIONAL SPECIFICATION left by the said William Bryden and John
William Wilkinson at the Office of the Commissioners of Patents on the 12th
November 1878.
WILLIAM BRYDEN and JOHN WILLIAM WILKINSON, both of Morley, near
Leeds, in the County of York. IMPROVEMENTS IN SCRIBBLING AND CARDING
MACHINERY."
The object of our Invention is to dispense with some of the working parts, and
at the same time to increase the efficiency of the machinery for scribbling and
carding.
According to our arrangement or improvements we employ any required number
of "swifts" of ordinary construction, and dispense with one set of strippers and
workers, also the angle strippers usually employed on each "swift," and employ
only one set of strippers and workers on each "swift," and use as a substitute for
the other set of strippers and angle stripper what is known as a "fancy" in addition
to the ordinary "fancy" now in use; or, in other words, we employ over each
"swift" two "fancies," one stripper and one worker, instead of one "fancy," two
strippers, two workers, and one angle stripper. Each "swift" is mounted on a
separate carriage, all being arranged so that they can be adjusted towards each
other, and on each carriage are mounted the stripper, worker, and "fancies" for
each "swift;" these are adjusted simultaneously with the "swifts."
The framework of the machine is of ordinary construction, and underneath the
"swifts" we provide a creeper sheet for receiving the waste material and conveying
it to some convenient position or place.
The transverse motion of the creeper sheet may either be continuous or inter-
mittent.

The framework of the machine is shewn at a, and is of ordinary construction.
b, b, b, b, are the "swifts;" these may be of any required number. We dispense
with one set of strippers and workers, also the angle stripper usually employed on
each "swift" b, and employ only one set of strippers c and one set of workers d,
and use as a substitute for the other set of strippers and angle stripper what is
known as a fancy" at e in addition to the ordinary "fancy" at f; or in other
words, we employ over each "swift" b two "fancies e and f, one stripper c, and
one worker d, instead of one "fancy," two strippers, two workers, and one angle
stripper. Each "swift" b is mounted on a separate carriage g, and arranged so
that they can be adjusted towards each other, such adjustment being effected
through the medium of the screw h, which is mounted in bearing i on the frame-
work, and working in nut k on. the carriage g. The required adjustment may be
effected by the attendant applying a key or other lever to the square end 7 of the
screw h, and turning the same right or left. Other equivalent means may be
employed for adjustment, such means being so arranged that the stripper, worker,
and "fancies" for each "swift" may be adjusted simultaneously. Rotary motion
may be given to the various parts from some suitable motor by ordinary means.
Underneath the "swifts" b is applied the creeper sheet m, which is carried on
the rollers or pulleys n and o, and motion given thereto either of a continuous or
intermittent character from some moving part of the machine. This creeper sheet m
is provided to receive any material that may fall from the "swifts" during the
scribbling or carding operation, such material being carried forward and deposited
on or into a suitable receptacle.

page_text: In order to assist in the operation of scribbling or carding we employ in some
cases the comb p (to which, when preferred, a vertical reciprocating motion may be
given, or the comb p may be stationary) and the rotary "brush" q, to which a
rotary motion is imparted.
The direction of the rotating part is shewn by arrows.
By the herein before described arrangement it will be readily observed by all
competent persons that not only do we dispense with one set of strippers, one set of
workers, and the angle stripper usually employed on each "swift," but we may also
dispense with the breast doffer and other intermediate doffers employed in the
ordinary arrangement of scribbling and carding machinery.
Having now described the nature of the said Invention and described by the aid
of Drawings how the same may be carried into practice, we would have it understood
that we do not limit ourselves to the exact details or configuration of the parts we
have described and shewn, as the same may be varied or modified without departing
from the nature or principle of our Invention, but what we claim and desire to be
secured to us by Letters Patent is,―
First. The arrangement and application of one set of strippers, two "fancies,"
and one worker in combination with "swifts," substantially as and for purposes
herein set forth.
Second. The arrangement and application of the means employed for adjusting
the "swifts," substantially as and for purposes herein set forth.
Third. The arrangement and application of creeper sheet m and parts connected
therewith, substantially as and for purposes herein set forth.
In witness whereof, we, the said William Bryden and John William Wilkinson,
have hereunto set our hands and seals, this Ninth day of May, in the
year of our Lord One thousand eight hundred and seventy nine.
