CERTAIN IMPROVEMENTS IN THE CONSTRUC TION OF SPINNING MACHINES
Year: 1824

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PRICE, of Stroud, in the County of Gloucester, Engineer, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fifth day of August, in the fifth year of His reign, did, for
Himself, His heirs and successors, give and grant unto the said John Price,
His especial licence that I, the said John Price, my exors, admors, and assigns,
or such others as I, the said John Price, my exors, admors, and assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years herein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN THE CONSTRUC
TION OF SPINNING MACHINES;" in which said Letters Patent there is contained
proviso obliging me, the said John Price, by an instrument in writing under
my hand and seal, particularly to describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, and to cause the
samo to be inrolled in His Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said in part recited
Letters Patent, as in and by the same, reference being thereunto had, will
more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Price, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained in and by the Drawings hereunto annexed, and the following
description thereof (that is to say) :-
My said improvements consist of the mode of spinning woollen or other
yarn, which I perform in the following manner :-
First, in spinning wool from the carding, I use an endless cloth for carrying
the carding to the spindles, the said cloth passing over a roller, which is
made to revolve by means of a toothed rack working into a toothed wheel
fixed on the axis of the same roller, as described in the Drawing. I also uso
a pressure roller acting on the revolving roller, and which I make of any
convenient length, so that its weight may be sufficient to keep the carding
from being drawn over during the time the twisting is going on. The rack
may be regulated so as to bring in any quantity of the cardings, according
to the size of yarn required. It is also made to bring a certain portion of
the said cardings every time the carriage or spindle frame is wound in, which
has the effect of preventing the ends or cardings from so easily braking off at
the instant the carriage begins to draw out.
Secondly, I wind in the carriage or spindle frame by mechanical means.
I perform this by applying two loose riggers on the first motion or drawing
axis; on to one of these loose riggers 1 fix a groove pulley carrying a lino
or band to the pulley which drives the twisting roller, the belt being guided
on to the rigger connected with the pulley causes the twisting roller and
spindles to turn slowly while the yarn is guided on in a proper shape.
The object of this method of winding in the carriage is to obtain
longer draughts than can be given when wound in by hand, the same being
applicable to many varieties of spinning machines. In spinning woollen
or other yarn from slubbing I use two rows of spindles in one frame, and
which said slubbing I conduct to the spindles by one, two, or more sets
of rollers; but in the annexed Drawing I have described two sets of
rollers, buth sets being placed equidistant from each row of spindles, in
order to obtain threads of the same length and size in both rows.
My next improvement is in the admission of slubbings or cardings to the
spindles. This consists in using a spur-toothed wheel working into the scroll
pinion, having a bevel wheel on the same axis communicating by a shaft and
other bevil wheels to the rollers. By this arrangement I have only to change
the scroll pinion when any difference is wanted in the size of the yarn, to effect
which by the usual method required two pair of bevel wheels to be changed as

the calculation of the number of teeth, and consequently produce bad yarn.
My mode of regulating the quantity of slubbings above described is in the
like manner applicable to cardings. In using the machine with two rows of
spindles, it is necessary to have a wheel on each of the bottom rollers, with
another wheel, which I call an intermediate wheel, working into both, motion
being given to one set of rollers which work the intermediate wheel, into
which the other roller which works both sets' revolve, in the same direction and
at the same time.
The above description will be more clearly understood by inspecting the
Drawings, where the same letters and figures refer to the same parts of the
machines. As the framework and many other parts constitute no part of my
improvements, I have drawn only what I consider necessary to elucidate my
Invention, all other parts being similar to the machines in common use for
spinning wool, cotton, and other yarn.
DESCRIPTION OF THE DRAWING.
Fig. 1, an end view of a machine for spinning from the cardings. (A), the
card; (B), the endless cloth; (C), the rack; (1), (1), the cloth rollers;
(2), the pressure rollers; (D), the carriage or spindle frame; (E), the
twisting roller, made of tin; (F), the spindle; (G), the driving rigger; (L),
the belt; (K), the band wheel; (J), a pulley; Q, a band; (M), scrool
pinion; (N), scrool wheel.
The operation of the machine is as follows:-The carriage is drawn
out by means of the scroll shewn at R, Fig. 4, by having a line fastened
to the carriage at (n), Fig. 1, the end being made fast to the scroll,
which being put in motion by the pinion (M) draws the carriage out
as the line is coiled on it. The spring catch (c) takes hold of the rack C,
which working into the toothed wheel (a), Fig. 3, causes the roller to revolve
and conduct the cardings to the spindles. When the catch (c) comes in
contact with the wheel (d) the rack is disengaged, and is taken back by the
weight (w) and line (9) passing over the pulley (h). The rack is supported
by the rollers (m, m). When the carriage returns the slide (f) strikes the
lever (e), which is moveable on the centre (t), and causes the rack to move
forward and turn the roller (1), which carries the carding towards the spindles.
In winding in the carriage the belt (L) is thrown on the loose rigger (H),
Fig. 2, which, having the pulley (I) attached to it, turns the pulley J,
by means of the band (9), and the band (Q) turning the twisting roller (E)
and spindles (F); the yarn is guided on by the attendant in the usual way.
