Improvements in Carding Engines.
We, BRINTONS LIMITED of Kidderminster in the County of Worcester, Carpet
Manufacturers, and EDWIN BEDFORD of 102 Lea Street, Kidderminster aforesaid,
Spinning Manager, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to carding engines and its object is to increase the
number of carding points and therefore the amount of carding surface in
connection with each card drum or "swift" whereby the number of drums or
swifts required for effecting a given amount of work may be reduced and the cost
of same and the floor space required considerably diminished.
According to our invention instead of arranging the workers singly around the
drum or swift with a separate stripper for each worker as heretofore, we combine
with each of the workers, or with some of them, a second worker driven in the
reverse direction and preferably at considerably greater speed. The teeth of these
two workers meet and above them is a stripper revolving in contact with both,
while another stripper revolves in contact with the faster worker and the drum or
swift. The stripper which revolves in contact with the two workers keeps the
slower one free from lapping and brings the wool or fibre round to the faster
worker which is in turn stripped by the stripper which revolves in contact with it
and the drum. It will readily be understood that for each of our pairs of workers
arranged as above described there are three carding points, viz. two at the points
where the two workers respectively revolve in contact with the drum and one
where they revolve in contact with each other.
When the wool or fibre on leaving the doffer of the drum or swift has to proceed
to another drum or swift, we arrange the doffer and this other drum to revolve in
contact with each other; we thereby effect an additional carding between the doffer
and this drum.

Improvements in Carding Engines.
We BRINTONS LIMITED of Kidderminster in the County of Worcester, Carpet
Manufacturers and SUSANNAH BEDFORD of 102 Lea Street, Kidderminster
aforesaid, Widow, Administratrix of EDWIN BEDFORD late of 102 Lea Street,
Kidderminster aforesaid Spinning Manager, deceased, 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 has reference to carding engines and its object is to increase the
number of carding points and therefore the amount of carding surface in connection
with each card drum or "swift" whereby the number of drums or swifts required
for effecting a given amount of work may be reduced and the cost of same and the
floor space required considerably diminished.

page_text: According to our invention instead of arranging the workers singly around the
drum or swift with a separate stripper for each worker as heretofore, we combine
with each of the workers or with some of them a second worker driven in the
reverse direction. The teeth of these two workers meet and above them is a
stripper revolving in contact with both while another stripper revolves in contact
with the faster worker and the drum or swift. The stripper which revolves in
contact with the two workers keeps the slower one free from lapping and brings
the wool or fibre round to the faster worker which is in turn stripped by the
stripper which revolves in contact with it and the drum. It will readily be
understood that for each of our pairs of workers arranged as above described
there are three carding points, namely two at the points. where the two workers
respectively revolve in contact with the drum and one where they revolve in
contact with each other.
When the wool or fibre on leaving the doffer of the drum or swift has to proceed
to another drum or swift we arrange the doffer and this other drum to revolve in
contact with each other; we thereby effect an additional carding between the
doffer and this drum.
Figures 1 and 2 of the accompanying drawings are elévations of the left and
right hand sides of a carding engine constructed in accordance with our
improvements.
Figure 3 is a diagrammatic view showing on a larger scale the arrangement of
two workers and two strippers grouped in the manner herein before described.
The engine shown comprises only two drums or swifts and two doffers but it
Devertheless has as many carding points or nearly so as a carding engine of the
ordinary construction with four drums or swifts.
A is the feeding drum or licker-in, B the first carding drum or swift and C the
second carding drum or swift. The wool or fibrous material is taken from the
licker-in A to the drum or swift B by the angle stripper D in the ordinary
manner. It is then carried on to the first worker E and stripper F which are
arranged in the usual way and constitute the first carding point. From these it
goes to the second worker G and stripper H where it is again combed or carded
and then to the third worker I. This third worker is directly at the rear of the
second worker G and so close that the material passing between is carded or
combed as will be readily understood by an inspection of Figure 3.
It will be seen that the surface of the second worker G moves in a contrary
direction to the surface of the swift B as indicated by the arrows, while the surface
of the third worker I moves in the same direction as the swift. These two workers
thus move in contrary directions; they are so covered that their points meet those
on the swift, and the points on the two workers also meet. It will be understood
that the wool or fibre left on the worker I by the swift is carried back in the
direction of the third stripper K which is in contact with both of the workers G
and I and picks off all the fibre from the worker I, carrying it in the direction of
the second worker G. The surface speed of this-worker is greater than that of
the stripper K; the fibre therefore taken from the surface of the stripper K and
carried downward towards the surface of the third worker I where it is again
carded or combed, thus forming the fourth carding point. The fibre now left on
each of these workers is carried downward towards the surface of the swift, where
after again being combed, the remainder is carried onwards by the workers, which
are in turn cleared by their strippers. The third worker I has the slowest surface
motion, the third stripper K goes a little faster, the second worker G still faster
acting both as stripper and worker, and the second stripper H goes fastest of all,
as it has to strip all the other three of the group.
From the foregoing description it will be understood that there are four carding
points up to and including the third worker I. The fibre is carried therefrom to
the fourth and fifth workers L and M and meets with another carding or combing
group similar to that last described, making three more carding points or seven in
From this group the fibre is carried to the doffer N where it is again carded
all.

page_text: or combed, this making eight carding points on the first swift B. The fibre is
carried on by the doffer N to the next swift C and the doffer is set close enough
to this swift to enable the latter to card or comb the fibre on its surface this
making the ninth carding point. The doffer N is cleared by the angle stripper P
and the fibre moves onward to a series of workers and strippers the same as those
on the swift B and already described. After this it is again carded or combed by
the back doffer Q and collected thereby. The rollers on the swift C being in
exactly the same position as on the swift B there are the same number of carding
points on it, namely eight, thus making with the carding point between the doffer N
and the swift C seventeen in all.
Thus is accomplished on two swifts only, practically the same amount of work
that it takes four swifts to do in an ordinary carding engine the number of carding
points on such being about eighteen.
The ordinary strippers in our carding engine are driven in the usual manner.
Each of the extra strippers is driven by a strap from the end of the ordinary
stripper that forms part of the same group as seen in Figure 1.
The ordinary or back workers are driven as shown in Figure 2 by a chain from
the doffer shaft in the usual manner, these as before mentioned working the slowest
of the group. The extra workers having to overcome the surface velocity of the
back worker and its stripper require a greater speed; they are therefore driven in
the case of the swift B as shown in Figure 2 by pulleys coupled by a belt to the
licker-in, the belt then passing over a carrying pulley to a pulley on the shaft
of the swift. In the case of the swift C the workers drive direct from the swift
shaft.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim in respect of carding engines is :-
1. The combination with a carding drum or swift of one or more groups of
workers and strippers, each such group consisting of two workers which are driven
in opposite directions and at different speeds and in contact with each other and
with the drum, and two strippers one of which is in contact with both the workers
and the other in contact with the faster driven worker and with the drum,
substantially as and for the purpose hereinbefore described and represented in the
accompanying drawings.
2. The improved carding engine constructed and working substantially as
hereinbefore described and represented in the accompanying drawings.
