I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer & Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVED APPARATUS FOR SPINNING, TWISTING, DOUBLING, & DRAWING
FIBROUS MATERIALS," to be as follows:-
This Invention consists of an apparatus termed a "twister," which may be
used with advantage instead of the flyer of the roving frame or other rotating
apparatus ordinarily employed for twisting fibrous materials, which improved
machine is simple, and requires little motive power to actuate it.
This
apparatus is represented in the annexed Drawing, where Fig. I is an elevation
partly in section; Fig. 2, a central vertical section; Fig. 3 shows the tube in
elevation and plan; & Fig. 4 shows the rollers h & h¹ full size. The same
letters of reference indicate like parts in all the Figures. a, longitudinal frames
connected by cross pieces c, which may be of any length according to the number
of twisters required to be used. At the ends of the frame are fixed supports
d, d', for carrying shafts 6, 61, on which are mounted skew pinions e, e¹;
the pinion & gears with a similar pinion f, which is mounted on an iron tube i,
the other pinion e' gears with a pinion f¹, which is loose on tube i; this pinion
may be fixed by means of a pin to a small bevil pinion g, which gears with a
similar pinion g', giving motion to a small iron roller h, which moves by

page_text: friction another roller h','kept in contact with the former by means of springs k,
as seen in Fig. 2. The tube i has continuations consisting of straight parts i,
which give motion to a receptacle j, according to the kind of work required to
be effected by the "twister." The action of the apparatus is as follows:-
The tube i receives motion from the shaft 6 by means of the gearing e&f; if
the gearing f&g were fixed, the pinions g, g¹, having the same number of
teeth, the tube in turning once on its axis, would also give one turn to the
pinion g¹, but by means of gearing & f¹, a speed may be communicated to g,
which will exceed that of tube i; thus supposing the speed of i&g to be the
same, the sliver of textile material will be held between the rollers h & h¹ without
their having any rotary motion in the direction of their circumference, and the
sliver would be twisted without traversing through the tube i, but as the speed
of the rotary motion of rollers h, h¹, on their axis may be varied as required,
the sliver may be drawn through at a greater or less speed, and have more
or less twist imparted to it in its passage.
The speed is varied simply by varying that of shafts b, 61, which is easily
effected by change wheels or pinions, which impart motion to them on one
side of the machine. The application of this improved principle is of great
importance in industrial operations; for example, by using this improved
apparatus, it is unnecessary to make use of the fly or other rotators used in
twisting, doubling, or spining various textile materials. This apparatus.is
adapted also to perform the drawing operation hitherto effected by the
machines herein mentioned machines. If reduced to small dimensions it may
be substituted for the spindle of all throstle frames, varying as required the
size of the receptacle j. It is also suitable for doubling and twisting thread;
when of larger & stronger dimensions this apparatus may be employed for
laying cord or rope. Fig. 5 is a.central vertical section of the bottom of the
can or receptacle j, showing the method of fitting it on a cone trunk with fly
wheel mounted on a centre pin l, fixed. to lever m, having a counterweight n
for balancing the receptacle j. When full, the pedal o serves for pressing
with the foot for the purpose of disconnecting the can. to be emptied as
required.
