Improvements in Machinery for Spinning, Drawing, and Doubling
and Twisting Textile Yarns and Threads.
THEODORE HOLMES, Roker Lane Top, Pudsey, near Leeds, Mill Manager, JOSEPH
KITCHIN, Steam Mills, Armley, Leeds, Woollen Manufacturer, and SAMUEL HAR-
GREAVES, Steam Mills, Armley, Leeds, Woollen Manufacturer, 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 :-
The object of this Invention is to produce an improved mechanism, by which
spinning, drawing and doubling and twisting of textile yarns and threads, can be
carried out, by a continuous motion, at one and the same time.
Figure 1 is an end elevation in section of a spinning frame, with invention
applied.
Figure 2 is an end elevation of our invention.
Figure 3 is a plan of upperside of the drawing rollers.
Figure 4 is a sectional an-end elevation of the second-method of our invention.
Figure-5,-is-a-plan of upperside of drawing rollers, spiral spring, and pin-wheel.
Figure 56; is a face view of the pin wheel.
In carrying out our object, the framework A, of the machine, is similar to that in
general use. Upon the framework A, over where the spindles are placed, a horizontal
bar B, is fixed the full length of the machine.
-
In this bar B, a series of holes are made that correspond in number to the spindles
in the machine, these holes being directly over the spindles. In each of these holes
one end of a tube C, is placed and upon this tube C, a grooved driving wheel c¹ is
fixed. Between the bar B, and the wheel c¹, a number of balls c², are placed in a
circular groove in the bar B, around the tube C, and when the tube C and wheel c¹,
are in motion, the latter runs freely around upon the balls c², and thus reduces the
friction, and the power required to drive the tube C and wheel c¹. Above the wheel
cla casting D is put upon and forms a bearing for the tube C, this casting D being
fixed to to the bar B. Above-the-easting D-n-loose-grooved wheel c³, is played upon
the-tube-C, which nets-as a drawing wheel, and between the easting D, and the
wheel c³-are a number of balls-c'; which are placed in a circular groove-on-the-upper
side of the casting D, around the tube C. The wheel c³, runs around azon the balls
c', reducing the friction. Upon the upper surface of the drawing wheel-e-are-n
required number of gear pegs or teeth-in-a-circle. At the upper end of the tube
C, two drawing rollers c, c, are placed in bearings, the spindle ends of these
rollers being kept in position by springs. Upon the end of the spindle of the
roller-c-a-gear wheel c³, is fixed, this gear wheel gearing with the pegs or teeth c
Above-the upper end-of the-tube-C, u Aut cap J is fixed by hinges, to the frame of
the-machine-and-through this cap-d, a-hole is made which comes directly-over-the
037

page_text: two-drawing-rollers-c-c'.-On-the-upper surface of the cap-I, a wire-eyelet-j¹-is
fixed.
A horizontal shaft-E; is fixed-the full length of the machine, this shaft-E-runs
parallel with the wheels-c. Upon this shaft E, a number of grooved wheels-e';
that correspond to the number of wheels care fixed, and above the shaft E, n
second-horizontal-shaft F, is fixed the full length of the machine, and this shaft F
runs-parallel with the-drawing-wheels-c³. Upon this shaft F, a number of grooved
wheels-1,-that-eorrespond in number to the wheels-c³-are-fixed.
The wheels c' and the wheels-e';-are-connected by endless bands G, and the
drawing wheels c³, and the wheels f1, are connected by the endless bands H. The
shafts E and F, are geared together, and are driven from the same-shaft that gives
motion to the spindles.
The-gear-wheels-on-the-shafts-E-and-E, are of different-diameters and number of
teeth, so that when they are put in motion, the wheels-c¹-run-quicker than the
wheels-and-give-the-required--twist--to--the-thread, and at the same time-n
continuous-draw is being given, by the motion of the drawing rollers.
Any required draw can be given to the threads, by means of change-wheels-on
the-driving-shafts.
In-a-second method of currying out our invention for spinning, drawing, and
doubling, and twisting yarns-and-threads, at one and the same time,-we-dispense
with-the-use-of-the-drawing-wheel-c³, the-gear-teeth-c", the-gear-wheel-c8, the-shaft F
the grooved wheels-/1, and the driving bands H, as described. In place of these
The casting D, at its upper part, is made in the form of a box d, Figure 24, and
around the upper edge of this box d¹, a spiral spring L, is adjustably fixed by screws
11, 12, 13. This spring hangs over the inside of the box d¹.
Upon the end of the spindle of the roller co, a pin wheel cº, is fixed by a key, the
pins co, upon the wheel cº, are fixed around the outer face of the wheel. Around the
tube 0, under the rollers c, c', a collar cl, is fixed, and in a circular groove in
the bottom of the box d¹, and around the tube C, are a number of balls d² upon which
the collar c bears. The collar cl, when in-motion-on the tube C is in motion,
runs freely around upon the balls d², with slight friction. A horizontal shaft E, is
fixed the full length of the machine, this shaft E runs parallel with the wheels c¹ and
the bar B upon this shaft E, a number of grooved wheels e¹, that correspond to the
number of wheels c¹ are fixed. The wheels c¹ and the wheels el are connected by endless
bands G. The shaft E is driven from the same shaft that gives motion to the spindles.
In-this-second-method of carrying out our invention, the The wheels c¹ are driven
by the bands G as described, giving the twist to the thread, and at the same time a
continuous draw is being given to the thread by the action of the pin wheel, by one
pin on the wheel, travelling under the spring L, being caught at each revolution at
the lower end of the spring at , and travelling over the spring to 5, the next pin is
caught at , this motion continuing as long as the machine is in operation.
.
Any required draw twist can be given to the thread, by changing the pin wheel to
a coarser or finer pitch, and at the same time raising or depressing the spring L, by
the screws 1, 13, to regulate it to the pitch of the pin wheel being used; and any
required twist draw can be given to the thread by increasing or decreasing the speed
of the driving wheel c. Above the upper end of the tube C, a flat cap J, is fixed by
hinges, to the frame of the machine, and through this cap J, a hole is made which comes
directly over the two drawing rollers co, c. On the upper surface of the cap J, a wire
eyelet j¹ is fixed.
The ordinary condenser or roving bobbins and tin rollers, and spindles are used in
the machine. The feed and guide rollers are also of the ordinary kind, but they are
placed in such a position that when a thread is brought from the condenser or con-
denser bobbin between them it comes vertically down to the hole in the cap J.
The working of this Invention is as follows:-A sliner or roving thread M is
carried from the condenser bobbin K¹, between the feed and guide rollers I, through
the hole in the cap J, then between the drawing rollers c, c7, and through the tube
C, to the spindle P, the portion of thread between the feed and guide rollers and the

page_text: drawing rollers, receive a requisite amount of twist during the spinning operation,
and in addition a draw is given to it, by the two drawing rollers c, c', at the same
time, the ordinary spinning of the thread is being carried on, on that portion, between
the tube C, and the spindle.
In the operation of combined spinning, drawing and doubling and twisting threads,
the ordinary creel o is used for the bobbins, cops, &c., N, and the wire guides a¹ at
the front of the machine can be utilised.
The additional thread or threads m¹ to be used in the doubling and twisting
operation are brought from the bobbins or cops N, on the creel o, over a guide wire a³,
that is above the rollers I, they are then carried down to the wire eyelet hole ¿¹, on
the cap J, and join the sliver or roving thread M from the condenser or condenser
roving bobbins, the whole being carried through the hole in the top of the cap J, and
thence between the drawing rollers cº, c', when the operation of twisting the threads
together is commenced.
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 :-
