PROVISIONAL SPECIFICATION.
Improvements in Scribblers or Carding Engines for Carding Fibrės.
We ERNEST CROWTHER and WILLIAM HENRY CROWTHER, botli of
Priestley Mills, Pudsey, in the County of York, Card Cleaners, do hereby
declare the nature of this invention to be as follows:-
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
fibre under operation thoroughly and with a saving of time and labour, also
allowing the fancy rollers to work with more effect, and so maintain the
<
"swifts" in better condition.
According to this our said invention the scribbler or carding engine is made as
ordinary but above the last "worker" and "fancy" roller on each of the "swifts,"
we mount an endless apron or lattice preferably covered with card clothing or
teeth, and as this apron or lattice travels when the machine is in motion it draws
off the fibre, or most of it from the last worker and carries it to a stripper which
removes it from the apron or lattice and delivers it on to the first worker of the
next or second swift and so on through the machine.
When the endless apron or lattice is not covered with card clothing we employ a
stripper to remove the fibre from the worker and deliver it onto the apron or
lattice.
We prefer that the fancy rollers should be covered with straight teeth that is
without heel or bend as ordinary.
By the use of our improvements the greater portion of the fibre passes from one
swift to the next one without coming in contact with the fancy roller or the doffer
and the fancy rollers have little else to do but to keep the swifts in working order
so that less fetling is required, and the doffers have only to remove the shorter
fibres, or that left by the stripper or apron from the swifts and all dirt and waste
falls to the ground between the doffer and the swift.

COMPLETE SPECIFICATION.
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, Card 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
fibre under operation thoroughly, and with a saving of time and labour also
allowing the "fancy" rollers to work with more effect and so to maintain the
swifts or cylinders in better condition and also to great saving in the fibrous
material under operation. According to this invention the scribbler or carding,
engine is made as ordinary but above the "fancy" roller, on each of the swifts

or cylinders we employ an endless apron or lattice, or a series of stripping rollers
said apron. lattice, or stripping rollers being preferably covered with card clothing
or teeth and as the apron or lattice travels or the stripping rollers revolve, when
the machine is in motion the fibre is drawn off, the last worker" or stripper
of the swift or cylinder according as the apron or lattice or rollers are arranged.
The fibre is carried by the apron lattice or rollers from the last worker or stripper
of the first swift or cylinder and delivered to the first worker or stripper of
the next or second swift or cylinder and so on through the machine there being the
arrangement of apron, lattice or rollers between each cylinder or swift and the
next succeeding cylinder or swift. When the lattice or apron is not covered with
card clothing we arrange said apron or lattice to work in connection with the
stripper which removes the fibre from the last worker and delivers it on to the
apron or lattice, but if the apron or lattice is covered with card clothing we prefer
that it should be arranged to work directly in connection with the last worker and
without the intervention of a stripper.
We prefer that the fancy rollers should be covered with straight teeth that is
without heel or bend as ordinary.
By the use of our improvements the greater portion of the fibre passes from one
swift or cylinder to the next without coming in contact with the fancy roller or
doffer thus the fancy rollers have little, work to do excepting to keep the swifts or
cylinders in working order and less cleaning is necessary. The doffers remove the
shorter fibres and that left by the stripper, apron, or rollers and all dirt and waste
falls to the ground between the doffer and the swift.
Such being the nature and object of the said invention we will now describe the
same fully by referring to the accompanying drawings in which
Fig. is a side elevation of part of a machine for carding fibrous materials
having our improvements applied thereto the apron or lattice 1 (which in this view
is not covered with card clothing) being in contact with the stripper 2 of the first
swift or cylinder 3 and this stripper 2 delivers the fibre on to the lattice or apron 1
by which the fibre is conveyed to the first worker 4 of the second cylinder or
swift 5.
Fig. 2 is a similar view to Fig. 1 but in this case the apron or lattice 1 is covered
with card clothing and the fibre is removed by said apron or lattice from the last
worker 6 of the first swift or cylinder 3 and conveyed to the first worker 4 of the
second cylinder or swift 5 and when the apron or lattice 1 is covered with card
clothing, as in this case no stripper such as 2 (see Fig. 1) is necessary.
Fig. 3 is a similar view to Figs. 1 and 2, but shewing an arrangement of stripping
rollers 7. 7 whereby the fibre is removed from the last worker 6 of the first
cylinder or swift 3 and conveyed by the series of rollers 7.7 to and deposited on
the first worker 4 of the second swift or cylinder 5. No stripper such as 2
(see Fig. 1) is necessary when stripper rollers are employed.
We prefer that the "fancy" rollers 8 should be covered with straight teeth or
radial teeth that is teeth without bend or heel as ordinary.
One of the above described arrangements is employed between each succeeding
swift or cylinder.
By the use of the above described improvements there is little or no fibrous
material fall between the cylinders or swifts when being conveyed from one to the
other and thus a great saving of the material under operation is effected. The
fibre being carried above the fancy rollers the latter have little to do but to clean
and keep in working order the swifts or cylinders and thus less "cleaning" is
necessary and more "workers" may be employed.
Having now particularly described and ascertained the nature and object of our
said invention and in what manner the same is to be performed we declare that
what we claim is :-
:-
Claim The use in combination with the rollers of carding cylinders of an

page_text: endless sheet or a series of rollers (the equivalent of such endless sheet) as and
for the purpose herein described and as illustrated by annexed drawings.
