Improvements in Scribblers or Carding Engines for Carding Fibres.
We ERNEST CROWTHER and WILLIAM HENRY CROWTHER both of Priestley
Mills, Pudsey in the County of York, Carding Engine Cleaners, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in scribblers or carding engine, or
machines for carding wool, cotton and other fibres, the object being to card the
fibres under operation thoroughly and with a saving of time and labour also
allowing the "fancy" rollers to work with a better effect, and so maintain the
"swifts" in a better working condition and to ensure a greater working surface on
each "swift" by the addition of a secondary or smaller swift and workers both
swifts being cleaned with one and the same fancy roller.
"
According to this invention we employ "swifts" and "workers as ordinary but
the first stripper roller is placed in such a position so as to remove the fibre from
the last worker and carry it by means of carded rollers, flats or a lattice over the
fancy roller which is placed between the two swifts, and deliver it to a second swift
and to a worker or workers. After the last worker on the swift we employ a
stripper which delivers the fibre onto a secondary or outside swift in combination
with which are a series of extra workers so that the fibre is further carded and
cleaned, by the secondary swift on the last doffer, then the first swift will again
card it on the same doffer. Between the secondary swift and the swift proper is a
fancy roller. In each case the main portion of the fibre is carried above, or over
the fancy roller and without coming in contact therewith so that the fancy rollers
have little else to do but clean the swift and keep them in working order so that
less "fettling" is necessary.
Supplementary rollers are employed for catching the fly, and also serve to break
or lessen the air draught.
We, ERNEST CROWTHER and WILLIAM HENRY CROWTHER, both of Priestley
Mills, Pudsey, in the County of York, Carding Engine Cleaners, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in scribblers or carding engines or
machines for carding wool, cotton, and other fibres, the object being to card the
fibres under operation thoroughly and with a saving of time and labour, while
allowing the "fancy" rollers to work with a better effect, and so maintain the
"swifts" in a better working condition, as well as to ensure a greater working
surface on each "swift" by the addition of secondary or smaller swifts and workers,
both swifts being cleaned with one and the same fancy rollers.

page_text: Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawing,
which shows a side elevation of a scribbler or carding engine, the thick black line
showing the course of the fibre through the machine.
According to our invention, we employ a swift 1 and workers 2. 2 arranged as is
customary, and place a doffer or worker 3 in such a position on the swift 1 as to
remove the fibre from the latter and carry it over the fancy rollers 5 and deliver it
onto a secondary or smaller swift 6 provided with workers 7. 7. After the last
worker 7 on the secondary swift 6, we employ a stripper 8, which delivers the fibre
onto the next swift 9, which is also provided with ordinary workers 2, 2. A doffer
or worker 10 strips the fibre from the swift 9 and delivers it onto a secondary or
outside swift 11, in combination with which are a series of extra workers 12, 12, so
that the fibre is further carded and cleaned by the secondary swift 11, and the
doffer 13 which removes the fibre from the secondary swift 11, will card and clean
the fibre with the swift 11. Between the swifts proper 1 and 9 and the secondary
swifts 6 and 11, are the fancy rollers 5,5 so placed that in each case the main
portion of the fibre is carried above, and clear of the fancy rollers, and without
coming into contact therewith, so that the fancy rollers have little else to do but
clean the main and secondary swifts, and keep them in working order with less
labour in "fettling."
Supplementary rollers 14, 14, are employed for catching the fly, and these also
serve to break or lessen the air draught.
The secondary or outside rollers may be applied to carding engines having only
one swift or cylinder, or to engines having two or more cylinders or swifts as
illustrated.
In place of the stripper rollers 3 and 10, a stripper formed of a lattice or chain
of cards may be employed to carry the fibre clear of the fancy rollers.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
(1) The general construction, arrangement, and combination of parts constituting
the improved scribbler or carding engine, as and for the purpose herein described,
and as illustrated by the accompanying drawing.
(2) In a scribbler or carding engine and in combination, a main swift, workers
arranged around same; a stripper or secondary swift, workers arranged around the
latter; and a fancy roller, the latter being so placed as to clean both the main and
secondary swifts, and the doffer or worker being arranged to carry the fibre clear
of the fancy roller, substantially as and for the purpose described.
Dated this 13th day of May 1895.
