Year: 1870

page_text: LETTERS PATENT to James Tomlinson, of Rochdale, in the County of
Lancaster, Machine Maker, for the Invention of "IMPROVEMENTS IN
DaniNG COMMON AND ATHER FIRROUS MATERIALS.
"
Sealed the 15th April 1871, and dated the 18th October 1870.
PROVISIONAL SPECIFICATION left by the said James Tomlinson at
the Office of the Commissioners of Patents, with his Petition, on
the 18th October 1870.
I, JAMES TOMLINSON, of Rochdale, in the County of Lancaster,
Machine Maker, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS
MATERIALS," to be as follows:-
My Invention is applicable to the coilers of carding engines and other
machines used in preparing cotton and other fibrous materials, and it
consists in certain improved combinations of parts whereby the sliver
may be twisted to a greater extent than heretofore possible, and deposited
in coils in the can.

page_text: When my improvements are applied to a carding engine the fleece of
fibres from the doffer is divided by flat wires introduced from above
between the teeth of the card clothing into two or more parts, and each
part is taken through a trumpet-mouth and between a pair of calender
rollers placed diagonally, the axles of which are connected to the
revolving top plate; these calender rollers are turned round by a toothed
wheel on the revolving plate, to which the ordinary diagonal spout is
fixed; both these plates are driven by wheels and pinions, and by a shaft.
The can is turned round by bevel wheels or other equivalents, and the
top of the can fits in a ring forming part of the revolving top plate.
The bottom plate supporting the can is supported on a hinged piece or a
piece moving up and down in slots, which is held up by a spring catch
or otherwise, and when the can is to be removed the spring catch or
other equivalent is unlatched by the foot of the attendant to allow the
hinged piece to fall, thereby detaching the bottom plate from the driving
gear and liberating the top of the can from the ring, the full can may
then be removed and an empty one put in its place without stopping the
machine to which the coiler is applied. When these improved coilers
are applied to cards the fleece of which is divided into several portions
the slivers may be sufficiently twisted to go at once to the spinning
machines.
These improvements are partly applicable to the ordinary coilers.
The cans fit into sockets on the can plates, and may be connected
thereto by angle vanes or ribs; by this arrangement the rings on the top
plate may be dispensed with; or instead of the rings I use antifriction
bowls mounted on studs on the coiler plate.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Tomlinson in the Great Seal Patent Office
on the 17th April 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES 3
TOMLINSON, of Rochdale, in the County of Lancaster, Machine Maker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eigteenth day of October, in the year
of our Lord One thousand eight hundred and seventy, in the thirty. 3

page_text: fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Tomlinson, Her special licence
that I, the said James Tomlinson, my executors, administrators, and

others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands; and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS MATERIALS," upon the
condition (amongst others) that I, the said James Tomlinson, my execu-
tors or administrators, by an instrument in writing under my, or their,.
or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent.
Office within six calendar months next and immediately after the data
of the said Letters Patent.
NOW KNOW YE, that I, the said James Tomlinson, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
My Invention is applicable to the coilers of carding engines and other
machines used in preparing cotton and other fibrous materials, and it
consists in certain improved combinations of parts whereby the sliver,
may be twisted to the desired extent and deposited in coils in the can.
And in order that my Invention may be fully understood, and readily
carried into operation, I will proceed to describe the accompanying three
Sheets of Drawings, reference being had to the figures and letters
marked thereon..
On Sheet. 1 Fig. 1 is an elevation of part of a carding engine to which
one of my improved coilers (shewn in section) is applied; and Fig. 2 is
a front view of the same; Figs. 3 and 4 are parts of the coiler; and
Fig. 5 is a modification of my improved coilers.
I wish to remark here that my improved coilers are equally applicable
to drawing frames and other similar machines.
In Fig. 1a represents the doffer, and 6 the doffing comb. The fleece
of fibres is in this instance supposed to be divided into four parts, as

page_text: shewn in Fig. 2, by flat wires introduced from above between the teeth
of the card clothing, as now customary; c is a cross beam connecting
the end frames of the machine; this beam is shewn best in Fig. 3, and
in it are the bearings for the short hollow shafts d, which are cast with
or fixed to the arms d¹ and twist plate d³, shewn best in Fig. 6 of
Sheet 2: To the upper part of each hollow shaft d is cast or fixed the
spur pinion d³. Within and supported by the twist plate d² is the ring
wheel e, to which the arms e¹ are cast, and the upper ends of these arms
are united by a hoop fitting on the lower end of the trumpet mouth e²,
which revolves in the hollow shaft d; to the trumpet mouth is fixed the
spur pinion e³. The sliver descending the trumpet mouth passes between
the calender rollers f, shewn in Fig. 8, which revolve in a bridle d*
secured to the twist plate d². The sliver is delivered by the calender
rollers to the diagonal spout 9, which is cast with or fixed to the
coiling plate g¹, the circumference of which is toothed and is driven by
the ring wheel e. The calender rollers are set at such an angle that the
sliver may be guided by them direct from the trumpet mouth e² into the
spout g. To the coiling plate is also cast or fixed the skew bevel
wheel g², which drives a pinion f¹ on one of the calender rollers f, the
two calender rollers being geared together by spur pinions, as now
customary. The twist plate and the coiling plate are driven at their
proper relative speeds to deposit the sliver in coils in the cans h by
means of the shaft i, see Fig. 3, on which are mitre pinions & gearing
into similar pinions cast with the spur pinions 2, which gear into and
drive the pinions d³ connected as before described to the twist plate, and
to the pinion is fixed the pinion gearing into and driving the
pinion c³. The relative speed of the plates d² and g¹ can be varied by
altering the number of teeth in the driving pinions, as heretofore. The
top of the can h fits in a ring projecting from the twist plate d³, and the
bottom fits in a recess in the ring j revolving in a groove in the hinged
plate k, see Fig. 4, which is jointed at ¹ to the bottom frame 1. The
ring is provided with a conical friction bush, which is driven by the
conical friction pulley m, cast with or fixed to a mitre pinion m³, which
is driven by a similar pinion n' on the shaft n. The hinged plate k is
held up while the can is being filled by the spring o, and it is held
horizontal by the slotted links o³, the slots fitting on studs projecting
from the bottom frame 1. When my improved coilers are applied to
carding engines the shafts i and n may be driven from the doffer, as
shewn by the dotted circles in Fig. 1, but when applied to drawing

page_text: frames and other machines the gearing must be modified accordingly.
As soon as the can is full or it is otherwise necessary to remove the can
the attendant with his or her foot depresses the front end of the plate k
until it assumes the position indicated by a dotted line; the top of the
can is thus lowered out of the ring on the twisting plate d², as shewn in
Fig. 5, and is consequently at liberty to be removed from the machine;
and as soon as the foot is taken off the plate k the spring o presses it
back to its original position, the conical friction bush j then again comes
in contact with the friction pulley m, and the can is thus made to rotate
as before.
The coiler shewn in section in Fig. 5 is very similar to that previously
described, but this coiler is designed for a drawing frame; the sliver or
slivers after passing between the front drawing rollers p, pass down the
hole in the bush e², which corresponds to the trumpet mouth e² in Fig. 1.
The gearing for driving the platej in which the can rests is also different
as the platej is cast with an internal ring wheel, into which the spur
wheel m gears, and as this spur wheel is turned round by the mitre
pinion m³, it is evident that when the plate k is horizontal, as shewn by
the full lines the can is carried round, and that when the plate k is
depressed to remove the can, as shewn in dotted lines, the ring wheel
drops out of gear with the spur wheel, thus stopping the rotation of
the can.
On Sheet 2 Fig. 6 is a section of the upper part of the coiler shewn
in Fig. 1. This section is drawn full size, and shews the mode of
connecting the coiler to a drawing frame. Fig. 7 is a plan of the
twisting and coiling plates; Fig. 8 is a detached view of the calender
rollers; and Fig. 9 is the bridle d' for supporting the calender rollers.
As all these parts have been referred to before, they are marked with
corresponding letters of reference.
On Sheet 3 Fig. 10 is a section of a modification of my improved
coiler. In this arrangement the outer circumference of the twisting
plate d revolves in a recess in the plate c, which is attached to the
roller beam q of the drawing frame or to the framing of the carding
engine. To the twisting plate d³ is cast or fixed the bracket d', in which
are secured the studs of the diagonal calender rollers fand the shank of
the trumpet mouth e². To the twisting plate d² is also cast or fixed the
toothed wheel d³, which is driven by the pinion 7, mitre pinions &¹, and

page_text: shaft i, as described in reference to Figs. 1 and 3. Within the twisting
plate d² and supported by it is the internal ring wheel e, which is cast
with or fixed to the external toothed wheel e", and this wheel is driven
by the pinion fixed to the pinion above described. The wheel e
drives the coiling plate g', as before, and the skew bevel wheel g² drives
the pinion f¹ on one of the diagonal calender rollers.f. By this arrange-
ment a considerable saving in height is effected, and the sliver is brought
with greater facility to the nip of the calender rollers f.
Fig. 11 is a section of the lower part of the coiler, shewing another
modification of machinery for giving motion to the can. In this
arrangement the plate on which the can rests is provided with a hollow
boss revolving in a bush in the hinged plate k, and to the plate j is also
cast or fixed the spur wheel j', which is driven by the pinion m, mitre
pinions and n and shaft n. The plate is pressed up by the spring o,
and it is held by the slotted links o¹, shewn best in Fig. 2.
Fig. 12 represents. a mode of connecting the can the the plate j,
whereby the can is secured to the plate instead of being loose in it, as
shewn in Figs. 1, 5, and 11. In the present arrangement the platej is
made with a deep rim, from which project internally three or other
convenient number of inclined ribs, which when the can is in its place
bind upon the pins / projecting from the lower part of the can.
Fig. 13 represents part of the twisting plate d³, which is made without
the rim for holding the top of the can, as shown in Figs. 1, 6, and 10.
In this case the can is held between three or more antifriction rolls do.
One advantage due to this mode of construction is that the operative can
see between the bowls d when the can is sufficiently full of slivers..
By means of these improvements in the construction and arrangement
of coilers they can be made to impart any desired amount of twist to the
sliver, and for some purposes the slivers so twisted may be taken direct
to the spinning machines. These coilers are particularly applicable for
operating upon the slivers produced by dividing the fleece from the
carding engines into several portions.
Having thus stated the nature of my Invention, and described the
manner of performing the same, I declare that I claim,―
First. The general combinations and arrangements of the parts
forming the improved coilers shewn and described.

page_text: Secondly. Placing the calender rollers of coilers in a diagonal position,
whereby the sliver may be conveyed direct to the spout in the coiling
plate, as shewn and described.
And, thirdly. The improved mode of supporting the can and liberating
it from the twisting plate, as shewn and described.
In witness whereof I, the said James Tomlinson, have hereto set
my hand and seal, this Fourteenth day of April, One thousand
eight hundred and seventy-one.
