Improvements in or applicable to Engines for Carding Cotton and
other Fibrous Materials.
We, JOSEPH SHEPHERD, of 31, Spring Wood Street, Ramsbottom, in the County
of Lancaster, Cotton Spinner and Manufacturer, and HITCHON HITCHON, of Cross-
field Mill, Rochdale, in the same county, Cotton Spinner, do hereby declare the
nature of the said invention, to be as follows:-
taker in ".
Our invention relates to the "licker in" or "taker in" of carding engines
(hereinafter called the "taker in") which are generally made with a series of
grate bars or mote knives under the lower surface of the "taker in " roller,
which hold back the loose shell, leaf sand and other foreign substances which
are intended to drop from between the bars or grid, but these bars are liable to
become clogged, and are not as effective in their action as desired, and the object
of our invention is an improved combination of mechanism with the
which will act in a more satisfactory manner than the arrangements hitherto
used for removing or separating the shells, leaf sand and other foreign sub-
stances from the fibres on the "taker in," thus preventing such substances from
passing to the carding cylinder, which if it gets there causes a deterioration in
the quality of the yarn, and more or less wear and tear and damage thereto, the
intention being to get rid cf as much of foreign substances as possible before
they arrive at the carding cylinder.
Our invention consists in applying a series of toothed rollers to the under
surface of the "taker in" roller, the points of the teeth of which rollers come
just clear or thereabouts of the points of the teeth of the "taker in," and the
toothed rollers adjoining each other are set to come near cach other and their
peripheries are all rotated slowly in the same direction so that any foreign sub-
stances loosened and retained by them will be allowed to drop from between
their lower sides as they rotate. The teeth of the rollers may be formed by.
toothed rings of metal and the teeth of one roller may be arranged to come into
the spaces between the teeth of the adjoining rollers, or the teeth may be con-
structed and arranged in any other convenient manner.
There is a part from or connected with each pedestal of the "taker in roller
to which brackets are secured, which form the bearings for each toothed roller,
which brackets are adjustable to bring the toothed rollers nearer to or further
from the teeth of the "taker in" and nearer to or further from each other.
By this arrangement when the "taker in" is adjusted, the rollers being all
carried by its pedestal are undisturbed in their adjustment in respect to the
taker in" and to each other. There may be a spur wheel on the feed roller
gearing with one on the nearest toothed roller, and a pinion attached to this
latter may gear with one loose on the end of the taker in shaft which wheel
will gear with a pinion fast on each of the other toothed rollers to drive them
all in the same direction, or other arrangements for driving the rollers may be
used

page_text: The teeth of the rollers may be ratchet shaped and all inclined in the same
direction except that nearest the card cylinder the inclination of the teeth of
which may be reversed in direction to those of the other rollers.
The teeth of the rollers may rotate in the same direction as the teeth of the
"taker in" but slower.
Our improvements, are applicable to "taker in" rollers when fed by a single
roller and curved dish or when fed by two rollers:

Improvements in or applicable to Engines for Carding Cotton and
other Fibrous. Materials.
We, JOSEPH SHEPHERD, of 31, Spring Wood Street, Ramsbottom, in the County
of Lancaster, Cotton Spinner and Manufacturer, and HITCHON HITCHON, of Cross-
field Mill, Rochdale, in the same County, Cotton Spinner, 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;-
Our invention relates to the "licker in" or "taker in" of carding engines
(hereinafter called the taker in which are generally made with a series of
grate bars or mote knives under the lower surface of the "taker in" roller,
which hold back the loose shell, leaf sand and other foreign substances which
are intended to drop from between the bars or grid, but these bars are liable to
become clogged, and are not as effective in their action as desired, and the object
of our invention is an improved combination of mechanism with the "taker in
which will act in a more satisfactory manner than the arrangements hitherto
used for removing or separating the shells, leaf sand, and other foreign sub-
stances from the fibres on the "taker in," thus preventing such substances from
passing to the carding cylinder, which if it gets there causes more or less wear
and tear and damage thereto, and deterioration in the quality of the yarn, the
intention being to get rid of as much of foreign substances as possible before they
arrive at the carding cylinder.
Our invention consists in applying a series of toothed rollers to the under
surface of the "taker in" roller, the points of the teeth of which rollers come
just clear or thereabouts of the points of the teeth of the "taker in," and the
toothed rollers adjoining each other are set to come near each other and their
peripheries, are all rotated slowly in the same direction so that any foreign sub-
stance: loosened and retained by them will be allowed to drop from between
their lower sides as they rotate. The teeth of the rollers may be formed by
toothed rings of metal and the teeth of one roller may be arranged to come into
the spaces between the teeth of the adjoining rollers, or the teeth may be con-
structed and arranged in any other convenient manner.

There is a part from or connected with each pedestal of the "taker in" roller
to which brackets are secured, which form the bearings for each toothed roller,
which brackets are adjustable to bring the toothed rollers nearer to or further
from the teeth of the "taker in" and nearer to or further from each other.
By this arrangement when the "taker in" is adjusted, the rollers being all
carried by its pedestal are undisturbed in their adjustment in respect to the
"taker in" and to each other. There may be a spur wheel on the feed roller
gearing with one on the nearest toothed roller, and a pinion attached to this

page_text: latter may gear with one loose on the end of the taker in shaft which wheel
will gear with a pinion fast on each of the other toothed rollers to drive them
all in the same direction, or other arrangements for driving the rollers may be
used.
The teeth of the rollers may be ratchet shaped and all inclined in the same
direction except that nearest the card cylinder the inclination of the teeth of
which may be reversed in direction to those of the other rollers.
The teeth of the rollers may rotate in the same direction as the teeth of the
"taker in" but slower.
Our improvements are applicable to "taker in" rollers when fed by a single
roller and curved dish or when fed by two rollers.

", represents part of the side framing of a carding engine.
, part of the main card cylinder..
e, the taker-in on a shaft in pedestals c¹, that can be adjusted to and from
the main card cylinder b, in the ordinary manner by means of the. screw nuts c².
d, is the lower and , the upper ordinary fluted rollers for feeding the lap of
fibrous material to the taker-in c, the lower feed roller d, being driven in
the ordinary manner by a. bevel wheel at one end (see Fig. 3).
From the pedestal c¹, at each end of the "taker-in" shaft, there is a segmental
plate c, which plates have slots concentric with the axis of the "taker-in," by
means of which the bearings el, for the shafts or "rollers e, hereinafter referred
to, can be adjusted and secured each by two bolts passing through slots in the
lengthway of the projections from the bearings e¹, (best seen in Fig. 2).
These bearings. e, are for the shafts e, the construction and arrangement of
which is best shown by Figs. 4 and 5. First there is a central shaft e, and a
series of rings e², and thin toothed discs e³, of metal, the toothed discs e³
and rings are alternate. These rings and toothed discs are secured on
the shaft e, in any convenient manner, say the ring at one end comes against a
shoulder on the shaft e, and a nut screwing on the shaft comes against the ring
at its other end so that when the nut is screwed against the ring, all the rings e²,
and toothed discs are pressed against each other and held from moving or
rotating on the shaft.e.
Ör instead of toothed dises e and rings, it is preferred, as less expensive
to construct, to form the shafts e, solid, and of the diameter of the metal rings,
where the teeth are to be, and to turn out grooves in the enlarged part of the
shaft and insert teeth therein formed out of straight flat wire, one edge of which
is toothed, and cut into lengths to go round the groove in the shaft, one length
being inserted in each groove and bent. round it, and is then secured by caulking

page_text: or riveting the metal of the shaft on each side of the groove to make it come
against the toothed wire when bent into the circle or ring form, and hold
securely in the groove. Or instead of turning out a separate groove for each
set of teeth as above explained, a screw groove is cut from end to end and the
flat wire toothed on one edge is inserted in this helical groove (the teeth of
course outwards) and secured at each end and all along or at intervals by caulk-
ing or rivetting as above explained or by other means.
These shafts with helically arranged teeth are or may be geared to keep rela-
tively in the same position to each other, especially if the teeth of one shaft c,
come between the teeth of the adjoining shafts e, as indicated in Figs. 3 and 5.
Other modes of constructing the toothed shafts may be employed.
At one end of each shaft e, for the toothed discs &³, a small spur pinion e', is
secured (see Fig. 2) and each pinion on each shaft (there axes being concentric
with the axis of the "taker-in") gears with a spur wheel e³, (see Fig. 2) which
is loose on the axis of the "taker-in" shaft c', or upon a sleeve projecting from
the pedestal of the "taker-in" shaft.
The spur wheel, is driven by gearing with a spur pinion d, on the lower
fluted roller & feeding the lap to the
taker-in" and thus all the shafts c, having
the toothed discs e³, or equivalents, are simultaneously rotated in the same
direction. There are other ways of driving the shafts e, having the toothed
discs 3, but the one described is preferred.
The shafts e, for the toothed discs pass through a slot (allowing sufficient space
for adjustment) in the side frames a The teeth of the discs e³, on the shaft c,
nearest the main card cylinder b, are or may be reversed in direction to the
toothed discs of the other shafts e.
The arrows on Fig. 1, show the direction of rotation of the main card cylinder d,
and "taker-in " c, the spur wheel e, has the same direction of rotation as the
"taker-in" (but slower) from the lower feed roller d, as above explained.
Figs. 6 and 7 illustrate modifications similar to those described by reference
to Figs. 1 to 5 except in the construction of the shafts e, which have blades or
flutes e, extending the lengthway of the shaft, instead of toothed discs e, and
they are arranged in relation to each other and to the "taker-in " as illustrated
by Fig. 8.
These shafts e, with thin blades e, may be constructed in any convenient
manner, for instance, rings are or may be secured at intervals upon the shaft e,
and each of these rings has or may have a radial groove in it at the intervals the
thin blades e, are to be apart. A thin blade extending the lengthway of the
shaft is placed in each radial groove of the rings so as to project above the rings
(see Figs. 8 and 9) and are then secured by solder or other means to the rings.
The shafts e, are adjusted so that the blades e, will just pass clear of each other
as shown in Figs. 8 and 9.
The shafts, are or may be rotated as described in reference to Figs. 1 and 2,
or the first shaft e, nearest the feed roller d, is or may be driven from it by a
spur wheel, and then one bladed shaft e, may drive the adjoining bladed shaft e,
by spur wheels, one spur wheel on one shaft gearing with the other on the
adjoining shaft. In this latter case each alternate shaft e, will rotate in the
opposite direction, but if desired the wheels on the shafts c. need not gear with
each other, but with an intermediate wheel on a stud in the part c³, from the
pedestal for the "taker-in" shaft.
In Fig. 6. the lap is fed by one fluted roller d, and concave dish in an ordinary
manner and in Fig. 7, the lap is fed between two fluted rollers and d', in an
ordinary manner.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
1. The combination with the "taker-in" of carding engines of a series of

page_text: rotary shafts having teeth or blades arranged under the "taker-in" substantially
as and for the purpose herein before described and illustrated by the drawings.
2. The combination with the taker-in" of carding engines of a series of
shafts having toothed discs arranged under the "taker-in
one of the lap feed rollers by gearing substantially as hereinbefore described and
illustrated by Figs. 1 to 5 inclusive of the drawings.
