Year: 1877

page_text: LETTERS PATENT to Samuel Brooks, of the Union Iron Works, West Gorton,
near Manchester, Machine Maker, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR SPINNING AND DOUBLING."
Sealed the 4th January 1878, and dated the 21st July 1877.
PROVISIONAL SPECIFICATION left by the said Samuel Brooks at the Office
of the Commissioners of Patents on the 21st July 1877.
SAMUEL BROOKS, of the Union Iron Works, West Gorton, near Manchester,
Machine Maker. "IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING."
This Invention consists,―
First. In connecting together all the thread rails and guide wires at both sides
of throstle spinning and doubling frames, so that they may be lifted simultaneously
previous to doffing, and again lowered into the working position. To accomplish
this all the thread rails are hinged to rails secured to brackets fixed to side shafts,
which are mounted in bearings fixed to the roller beam, and coupled together by a
cross shaft and toothed wheels or other equivalents. Each thread rail is independent of
the others, so that any one can be lifted as usual when required; or the thread rails
with the guide wires may be hinged to angle rails fixed on the side shaft. The mode of
actuating the side shafts, and connecting the guide rails to them, may be varied.
Secondly. In the application of a contracting cam to the copping motion of those
throstle spinning and doubling frames in which the yarn is wound in conical layers
on spools or bobbins having a flange below. The object of this contracting cam is
to increase the traverse of the lifting rail as the bottom of the cop is filled.
The contracting cam consists of a segment fitting in a disc; the segment is con-
nected to a screw,
which is turned partly round by a catch, and ratchet wheel, and
bevel wheels, or other equivalents at every vibration of the heart lever forming part
of the copping motion. At the commencement of a set the segment is at its
greatest distance from the axis of the disc, and it is gradually brought nearer to the
disc as the bottom of the cop is being built.

page_text: Thirdly. In an improved apparatus for preventing the accumulation of loose
fibres on the travellers or copping rails of ring and traveller throstle spinning and
doubling frames. Between each pair of spindles is placed a small double bracket,
the position of which can be adjusted by regulating screws. Each end of each
bracket is set to clear the travellers on the rings, and near enough to intercept or
strike off the fibres carried round by the travellers. The above double brackets
answer for two travellers, but single brackets may be used to each ring.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Samuel Brooks in the Great Seal Patent Office on the 21st January
1878.

This Invention consists,-
First. In connecting together all or any number of the thread rails and guide
wires at both sides of throstle spinning and doubling frames, so that they may be
lifted simultaneously previous to doffing, and again lowered into the working
position.
Secondly. In the application of a contracting cam to the copping motion of those
throstle spinning and doubling frames in which the yarn is wound in conical layers
on spools or bobbins having a flange below. The object of this, contracting cam is
to increase the traverse of the lifting rail as the bottom of the cop is filled.
And, Thirdly. In an improved apparatus for preventing the accumulation of loose
fibres on the travellers and copping rails of ring and traveller throstle-spinning
frames.
And in order that my Invention may be fully understood I will proceed to
describe the accompanying Sheet of Drawings, in which,-
Fig. 1 is a plan, and Fig. 2 a section of my improved mode of connecting the
thread rails and guide wires of throstle spinning and doubling frames.
a, a, are the roller beams forming part of the throstle frame; the bearing b, b,
fixed to the under side of the roller beams support the side shafts c, c, to which are
fixed small brackets carrying the rails d, d; to these rails the ordinary thread rails
e, e, with the guide wires are hinged. The side shafts c, c, are connected together
at one end of the frame by means of the cross shaft c¹ and the mitre pinions, shewn
in Fig. 1, or in any other convenient manner.
By applying a handle to the square end of the cross shaft c¹ all the thread rails
and guide wires can be brought into the position, shewn in dotted lines in Fig. 2,
to allow the bobbins to be doffed, and as the thread rails e are hinged separately to
the rails d, it is evident that any thread rail can be lifted as usual if required; or
the thread rails with the guide wires may be hinged to angle rails fixed on the side
shafts.
The mode of actuating the side shafts, and connecting the guide rails to them,
may be varied.

page_text: Fig. 3 is an elevation, and Fig. 4 a plan of part of an ordinary ring and traveller
throstle-spinning and doubling frame, to which my improved expanding cam is
applied.
The heart j, fixed on the shaft j, acts on a bowl in the lever k, at the end of
which is a stud k¹, on which is mounted the ratchet wheel k², and at every depression
of the lever k, by the revolving of the heart j¹, the ratchet wheel 2 comes in contact
with and is turned partly round by the tumbler catch p, which is hinged to a
bracket fixed to the framing.
When the lever k rises after it has been depressed, the ratchet wheel lifts the
tumbler catch, which regains its horizontal position when the ratchet wheel has
passed. To the boss of this ratchet wheel is cast or fixed the spur pinion ³, which
gears into the change wheel fixed to the end of a short shaft, which revolves in
bearings in the lever k. To the shaft 7 is fixed a worm 12 gearing into the wheel m¹
fixed on the short cross shaft m, which also revolves in bearings in the lever k.
The parts above referred to are made partly as usual, and partly as described in
the Specification of former Letters Patent granted to me, in conjunction with George
Harrison, on the 9th day of February 1877, No. 558.
At the end of the shaft m is the chain pulley m², which is connected to the ex-
panding cam fixed to the right-hand lifter shaft f by the chain m³. The contracting
cam consists of the disc f¹, which is keyed to the shaft f, and to which the end of
the chain m³ is secured; to the disc f' is cast or fixed the plate f2, in which is a
groove for the segment block 3; this block is cast with a nut for the screw f¹, and
at the end of this screw is the bevel pinion fo. In line with the lifter shaft is the
short shaft g, which revolves in a bush fixed to the framing. On this shaft are the
ratchet wheel g¹ and the bevel wheel g² gearing into the pinion f³. On the shaft
m is the catch h, which takes into the ratchet wheel g', and this ratchet wheel is
also provided with a retaining catch h¹.
At every vibration of the heart lever, the catch h in descending moves the
ratchet wheel g partly round in the direction of the arrow in Fig. 3; the wheel g
gearing into the pinion f³ then causes the screw f' to revolve in the proper
direction for bringing the segment block f³ nearer to the axis of the shaft f. At
the commencement of a set the segment block is at its greatest distance from the
axis of the disc, and it is gradually brought nearer to the disc as the bottom of the
cop is being built. By this means the traverse of the lifting rail is gradually
increased as the bottom of the cop is being filled, and as soon as the bottom of the
cop is full, the catch his thrown out of gear, so that the remainder of the cop may
be built of successive conical parallel layers in the following manner:-The cam met
fixed to the chain pulley m² raises one end of the double catch i, see Fig. 5, and
lowers the other end, thereby bringing the screw i¹ against a projection from the
catch h, and lifting it off the ratchet wheel g¹.
When the cops are full the attendant, by turning the hand wheel g³, brings the
segment block f³ out again ready for the next set.
Figs. 6 and 7 represent my improved apparatus for preventing the accumulation
of loose fibres on the travellers and copping rails of ring and traveller throstle
spinning frames. Between each pair of rings is placed a small double bracket y, the
position of which can be adjusted by regulating screws. Each end of each bracket
is set to clear the travellers on the rings, and near enough to intercept or strike off
the fibres carried round by the travellers. The above double brackets answer for
two travellers, but single brackets may be used to each ring.
Having thus stated the nature of my Invention and described the manner of
performing the same, I declare that I claim,-
First. The improved mode of connecting all or any number of the thread rails of
throstle spiuning and doubling frames to facilitate the doffing, as shewn and
described in reference to Figs. 1 and 2.
Secondly. The use of a contracting cam to increase the traverse of the lifting rail
when forming the bottom of the cop, as shewn and described in reference to Figs. 3,
4. and 5.

page_text: And, lastly. The improved apparatus for preventing the accumulation of fly in
ring and traveller throstle-spinning frames, as shewn and described in reference to
Figs. 6 and 7.
In witness whereof, I, the said Samuel Brooks, have hereunto set my hand
and seal, this Eighteenth day of January, One thousand eight hundred
and seventy-eight.
