PROVISIONAL SPECIFICATION.
Improvements in Carding Engines.
We, TOM LISTER, of 30 Stile Common, Huddersfield, in the County of York,
Commercial Traveller, and CHARLES DARNLEY, of Bay Hall Mills, Huddersfield
aforesaid, Card Maker do hereby declare the nature of this invention to be as
follows:-
This invention is designed to improve the carding engine as ordinarily constructed;
i.e., where two or more ordinary cylinders are employed; and the object is effected
by combining with the two or more cylinders, and between cach two cylinders, of
two or more doffers arranged between two cylinders, and within the space between
the said cylinders and duffers, one or more cleaning rollers are (preferably) employed.
Such cleaning roller or rollers also operate as sharpener or sharpeners for the wire
on the cylinders and doffers.
In another construction we employ as before two or more cylinders as ordinary
employed in a carding engine, and apply between each two cylinders an endless
chain of flats, or an endless sheet of cards passing over guide rollers, so as to keep
the card flats or endless sheet of cards in an angular formation and in contact with
each two cylinders. The said endless flats or the endless cards may be applied
above the cylinders; or the flats or endless sheet of cards may work over guide
pulleys and occupy the centre space between the two cylinders.
A cleaning roller or cleaning rollers may be applied in the space between the
two or more cylinders, and the flats or endless sheets of cards; said cleaning rollers
are worked in contact with the wire of the flats and of the cylinders, so as to operate
as a sharpener or sharpeners.

Improvements in Carding Engines.
We, TOM LISTER, of 30 Stile Common, Huddersfield, in the County of York,
Commercial Traveller, and CHARLES DARNLEY, of Bay Hall Mills, Huddersfield
aforesaid, Card Maker, 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 is designed to improve the carding engine as ordinarily constructed;
i.e. where two or more ordinary cylinders are employed and the object is effected
by the combination with the two or more cylinders, and between each two cylinders,
of two or more doffers arranged between two cylinders; and within the space
between the said cylinders and doffers, one or more cleaning rollers are (preferably)
employed. Such cleaning roller or rollers also operate as sharpener or sharpeners
for the wire on the cylinders and duffers.
In another construction we employ, as before, two or more cylinders as ordinarily

page_text: employed in a carding engine, and apply between each two cylinders an
endless chain of flats passing over guide rollers, so as to keep the card flats in
an angular formation and in contact with each two cylinders. The said endless
flats may be applied above the cylinders; or the flats may work over guide pulleys,
and occupy the centre space between the two cylinders.
A cleaning roller or cleaning rollers may be applied in the space between the
two or more cylinders and the flats; said cleaning rollers are worked in contact
with the wire of the flats and of the cylinders, so as to operate as a sharpener or
sharpeners.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the annexed drawings, in
which :-
Fig. 1 is a side elevation of such part of a carding engine as is necessary to
illustrate the application of our improvements thereto, shewing the two doffers
between the two cylinders.
Fig. 2 illustrates the two doffers applied to two cylinders, the upper doffer being
angular in the form of a chain of flat cards running over guides, instead of the
ordinary circular form of doffer.
Fig. 3 is the same as Fig. 2, save that the circular doffer is the uppermost, and
the angular doffer is below.
Fig. 4 shews angular flats as the top doffer, and as a substitute for the lower
doffer an angular guide plate for conducting the fibres when all the fibres left by
the top doffer are to be conducted to the cylinder 1 when extra or further carding
is desirable.
At 1, 1 are the ordinary cylinders, 2 and 3 are the top and bottom doffers, 4 is
the fancy roller, 5 and 6 are the last doffers, at 7, 8, and 9 are brushes or felt
covered rollers; the other rollers shewn are the ordinary angle rollers, strippers,
and workers. The direction of rotation of the several parts being indicated by
arrows.
The action is as follows:-The top doffer 2 by its relative speed, that is to say,
slow speed compared with the cylinder 1, receives a large proportion of the fibres
from the latter, and which it carries to the cylinder 1", the fibre being again carded
between the teeth of the top doffer 2 and the cylinder 1". The larger proportion
of the fibres being transferred by the top doffer from the cylinder 1, to cylinder 1",
there is but a relatively small quantity of fibre remaining in cylinder 1 to be operated
upon by the fancy 4; the latter can be adjusted or so set that its teeth project more
or less into the cards of the cylinders 1 and 1º, and thereby effectually brush up
and raise all fibres and accumulations outo the surface to be dealt with by the
cylinder 1 and bottom doffer 3, and when it is desired to effect the nearly complete
removal of the fibre from the cylinder 1 at each revolution; this is accomplished
by the doffer 3 receiving the raised fibres, and carrying the same to the stripper 10,
the surface of the doffer 3 moving at a greater speed than the surface of the
stripper 10, delivers the fibres to the cards thereon, above which is the stripper 11
revolving in opposite direction to the stripper 10, and while stripper 11 intercepts
any escaped fibre, and at the same time straightening out any fibre on the stripper 10;
the two strippers 10 and 11 thus presents the fibres to be taken by the cylinder 1;
these fibres being thus comparatively loose on the cylinder 1º, they would be thrown
off but for the intervention of the brush or felt covered roller or angle bar 8 which
brushes or lays the fibres into the cylinder 1ª, and thus enables the fancy or cleaner
to operate, and so avoid making excess of fly or waste; these fibres are then carried
forward by the cylinder 1° to be mixed and carded with the fibres passing between
the cylinder 1 and the top doffer 2, then passing along the cylinder 1, and are
worked by the ordinary strippers and workers to the two doffers 5 and 6, and thence
to the stripper.
When the main bulk of the fibre is to be removed from the cylinder 1, the
operations are as just described above, but when the fibres are to be subjected to a
further carding, the brush 7 is so adjusted as to work against the cylinder 1, thus

page_text: returning the fibres to the cylinder 1 after they had been raised by the fancy 4,
thus determining the quantity to be taken off by the doffer 3, causing the remainder
to be taken by the cylinder 1 to the brush 9, which brushes the fibres to the cylinder
and prevents waste; the fibres thence pass to the ordinary strippers and workers
around the cylinder 1. The roller 7 is not indispensible, but I prefer to use it, and
it may be either a card covered roller or an emery roller.
Referring to Fig. 2 (Sheet 2) the top doffer 2, in lieu of being cylindrical, as in
Fig. 1, is angular, consisting of a chain of flats 2 working over the guide
rollers 2, 2, the bottom doffer 3, cylinders 1, 1ª, fancy roller 4 (last doffers 5, 6
are same as in Fig. 1 but not shewn) 8 a brush (or in lieu of 8, an angle bar 9 may
be used) and 11 circular stripper, are all as described in reference to Fig. 1.
In Fig. 3 the order of the top doffers 2 and bottom 3 is changed from what just
described, in relation to Fig. 2-that is to say-the top doffer is cylindrical, but
the bottom doffer 3 is angular as in Fig. 2.
The cylinders 1, 1 being similar to those described in Figs. 1 and 2. At 4 is the
fancy for raising or brushing up the fibres on cylinder 1, the fibres thence pass onto
the angular doffer 3 and are taken off by stripper 8 and received by cylinder 1*.
In Fig. 4 the top doffer 2 is shewn as angular, but may be circular as in Figs. 1
and 3, the fancy 4 being partly enclosed by a guide plate 3 (which is in substitution
for the doffer 3 in other figs.) for conducting the fibre after being raised by the
fancy 4, back to the cylinder 1.
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, combination, and arrangement of parts described
herein, and illustrated by Fig. 1 of the accompanying drawings.
(2.) The combination of two cylinders and two doffers having intervening fancy
roller or rollers as described, and illustrated by Figs. and 3 of the annexed
drawings.
(3.) The combination of two cylinders and one doffer, and the guide or equivalent.
for second doffer, as illustrated by Fig. 4 of the drawings annexed hereto.
