CERTAIN IMPROVE-
MENTS IN MACHINERY FOR SPINNING AND DOUBLING."
Our Invention is particularly applicable to the machines known as the ring and
traveller spinning and doubling frames, and it consists,―
First. In an improved combination of machinery for building the bottom of the
cop on a plain spool; this machinery consists of a ratchet wheel connected to a lever,
which is pressed down by the heart; the ratchet wheel when pressed down comes
against a stop to turn it partly round. On the axle of the ratchet wheel is a change
pinion gearing into another fixed to the same shaft as a worm gearing into a worm
wheel fixed to the same shaft as a cam, which acts on the chain of the lifting bowl.
As soon as the bottom of the cop is formed the chain acts on the concentric part of
the cam, and the remainder of the cop is then built of conical parallel layers.
Secondly. In the application of elliptical wheels for lowering the ring rail rapidly
in order to tie the yam round the nose of the cop, or the same result can be
obtained by a cam with a sudden drop to be used in lieu of the ordinary heart.
And, Thirdly. In making the holsters and footsteps of the spindles so that they
may be adjusted to coincide with the centres of the rings. Attempts have been made
to adjust the rings to the spindles, but our Invention consists in making the boss of
the bolster and the boss of the footstep smaller than the holes through which they
pass in the bolster and footstep rails, and in securing the said bolsters and footsteps"
to their rails by screws passing through side flanges, or by nuts on the screwed ends.
of the bosses, which nuts are tightened against the under side of the rails.

MENTS IN MACHINERY FOR SPINNING AND DOUBLING."
Our Invention is particularly applicable to the machines known as the ring and
traveller spinning and doubling frames, and it consists,-
First. In an improved combination of machinery for building the bottom of the
cop on a plain spool.
Secondly. In the application of elliptical wheels for lowering the ring rail rapidly
in order to tie the yarn round the nose of the cop, or the same result can be
obtained by a cam with a sudden drop to be used in lieu of the ordinary heart.
And, Thirdly. In making the bolsters and footsteps of the spindles so that they
may be adjusted to coincide with the centres of the rings.
And in order that our Invention may be fully understood and readily carried
into operation, we will proceed to describe the accompanying Sheet of Drawings,
in which Fig. 1 is an elevation, Fig. 2 a front view, and Fig. 3 a plan of part
of an ordinary ring and traveller spinning or doubling frame to which our improve-
ments are applied.
a, a, are the spindles, which are supported as usual in a bolster and footstep fixed
in the bolster and footstep rails, as asual; a¹, are the spools, the bottom flanges of
which bear upon the shoulder a fixed to the spindle; b, b, are the ring and
traveller rails; c, c, the driving drums; d, the upright shaft for driving the lifting
motion, on which is fixed a worm d, gearing into the wheel e¹ on the shaft e; f
are the lifting shafts, which are united by the chaing passing around the pulleys;
fand, are the pulleys for the chains 13 connected below to the cross rail,
which supports the ends of the "pokers" i; the upper ends of the pokers are fixed
to the rails b.
The heart, fixed on the shaft j, acts on a bowl in the lever All these parts
and the others requisite to complete the frame, and which are not particularly
referred to hereafter, are made in the usual manner.
At the end of the lever is a stud, on which is mounted the ratchet wheel ²,
and at every depression of the lever by the revolving of the heart the ratchet
wheel 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 rises 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, which gears into the change wheel fixed to the end of a short shaft l,
which revolves in bearings in the lever . To the shaft is fixed a worm gearing
into the wheel m' fixed on the short cross shaft m, which also revolves in bearings
in the lever . To the shaft m is also fixed the cain m2, which is connected to the
pulley on the right-hand lifter shaft by the chain m³.
At the commencement of a set the lower end of the chain m³ is passing around
the smallest radius of the cain m², as shewn in Fig. 1, thereby imparting the least
amount of up-and-down motion to the rails b, and consequently causing the yarn to
accumulate at the bottom of the spool to form the beginning of the cop; as the
frame continues to work the larger radius of the cam comes into action until the
bottom of the cop is built, at which time the chain m³ is acted upon by the greatest
radius of the cam, and after the bottom is formed the remainder of the cop is built
up of conical parallel layers, which are produced by the concentric part of the cam
and the usual copping motion.
In ordinary throstle spinning and doubling frames the shafts e and j are connected
by spur wheels, and the rising and falling of the rails bare performed at the same
speed, but by connecting the said shafts by the elliptical wheels e² and j², as shewn

page_text: in Fig. 1, the lowering of the rail is more rapid than the lifting, consequently the
yarn forming the nose of the cop is tied or bound together, thereby preventing
waste. The same object may be attained by the cam with a sudden drop, as shewn
in Fig. 4, in lieu of the ordinary heart.
Fig. 5 represents a plan, and Fig. 6 a transverse section of our improved bolsters;
in these views, n is part of the bolster rail, and o is the bolster, the boss of which is
smaller than the hole in the bolster rail through which it passes. The bolster is
provided with side flanges, in which are slots for the screws which secure the
bolsters to the rails.
Fig. 7 is a modification of the bolster; in this case the boss is partly above and
partly below the side flanges.
Fig. 8 is another modification of our improved bolster; in this case the side
flanges are dispensed with, and the lower end of the boss is screwed to receive a nut,
which secures the bolster to the rail.
Fig. 9 is a transverse section, and Fig, 10 a plan of our improved footstep g, which
is connected to the footstep rail in the same manner as the bolster above described,
in reference to Figs. 5, 6, and 7. By lengthening the boss of the footstep and
screwing it the footstep may be secured in the manner described in reference to
Fig. 8.
When the bolster and footstep are secured to their respective rails by screws
passing through side flanges we prefer to place the flanges of the footstep at right
angles to those of the bolster for facilitating the adjustment.
Having thus stated the nature of our Invention, and described the manner of
performing the same, we declare that we claim as our improvements in ring and
traveller spinning and doubling frames,-
First. The improved combination of parts for building the bottom of the cop on a
plain spool, and particularly the cam m², as shewn and described.
Secondly. The application of elliptical wheels, or a cam with a sudden drop for
giving a rapid lowering motion to the ring rail, in order to tie the yarn round the
nose of the cop, as shewn and described.
And, Thirdly. The improved modes of securing the bolsters and footsteps to the
bolster and footstep rails for facilitating the adjustment of the parts, as shewn and
described.
In witness whereof, we, the said Samuel Brooks and George Harrison, havo.
hereto set our hands and seals, this Nineteenth day of May, One thousand
sight hundred and seventy-seven
