TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
SPENCER, of Bolton-le-Moors, in the County of Lancashire, Mechanic,
send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
MACHINERY FOR SPINNING COTTON, SILK, WOOL, AND OTHER FIBROUS MATERIALS
INTO YARN, AND WHICH MAY ALSO BE USED FOR DOUBLING THE SAME, AND IN EACH
CASE WINDING THE YARN ON TO A SPINDLE IN THE FORM OF A COP," and

page_text: bave petitioned Her Majesty to grant unto me, my executors, adminis-
trators, and assigns, Her Royal Letters Patent for the same, and have
made solemn Declaration that I am the true and first Inventor
thereof.
NOW KNOW YE, that I, the said Thomas Spencer, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement
This Invention consists of an arrangement of shafts, wheels, and
pullies fixed in a frame, and principally of a new form of spindle box
and spindle, and apparatus and appliances for working the same, and
has for its object the saving of room and space, and the substitution of
the spinning and roving machinery now in use. The advantages are
these-It will take up less room, and will be less expensive. It is
intended as a substitute for the spinning and roving machinery now in
use; and another advantage is that it can be used for doubling yarn
as well as spinuing it, and saves labour in so far that the spinner will
not have the trouble of "putting-up," as it is called, and having to
build the cop, as it were, himself, as the machine builds the cop
itself.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a front view of machine.
No. 1 is the driving shaft on which is a loose and fast pulley for
driving the machine. No. 2 is a pulley for the purpose of driving the
spindle roller (not shewn in Fig. 1, but the form of which is shewn in
Fig. 3). No. 3 is a small wheel on No. 1 connected with a train of
wheels for driving the rollers for delivery of material to spindle. No. 4
is a wheel on No. 1 geared into the wheel No. 5 for driving the shaft
No. 6. Nos. 7 and 8 is the top and bottom rail of spindle box. This
spindle box slides up and down between the two rails 9 and 10 on the
rods 11, 12, 13. No. 14 is a shaft having a thread screwed on it a
certain distance for the purpose of traversing the cone No. 15 on the
tube shaft No. 16. This screw shaft and tube shaft are driven from the
shaft No 6. by the wheels 17, 18, 19, 20. The cone has a nose or
projection for the whole length, small at the large end and gradually
increasing in size up to the small end (each end view is given in Fig. 6).

page_text: This cone is for the purpose of working the spindle box up and down
between the two rails, which it does by the nose coming into contact
with a lever at the back of the machine (lever not shewn in Fig. 1,
but shewn in Fig. 2 in contact with cone), which it pushes back, and in
doing so pulls at a chain which is fastened to the pulley No. 21 on
the shaft No. 22, and pulling the said shaft partly round raises the
spindle box by means of chains attached to the rods Nos. 23 and 24 of
the spindle box, and as the nose passes round and away from the lever
the spindle box gradually falls by its own weight, and is again raised
when the cone pushes the lever again, and so goes on working in this
manner. On the shaft No. 22 are also other pullies with weights
attached, these pulling the same way as the lever lessens the strain on
the cone.
The cone, screw shaft, tube shaft, and lever are shewn in
Fig. 2. The cone is traversed on the tube shaft by the screw shaft
turning in nuts attached to the ends of the cone (as shewn in Fig. 6);
the nuts go inside of the tube, and the small part or arm of the nut
works in and along the slot shewn in the tube in Fig. 2; the slot is
cut in both sides of the tube. The cone is what I term the cop builder.
The lines No. 25 are intended to shew the rollers, fluted and otherwise;
they are fixed in the ordinary way. No. 26 is a rod holding bent wires
for the purpose of guiding the yarn over the spindle (it is shewn in
Fig. 5). Attached to the end of the rod is a lever or arm, No. 27; this
arm rests on the lever shewn, No. 1 in Fig. 2, and as the lever is
pushed back by the cone it raises the arm No. 27, and depresses or
lowers the wires towards the spindles at the same time as the lever
raises the spindles; this is done in order to give length of yarn to the
spindles, which by the sudden lift given to them would otherwise break
the ends of the yarn. The form of spindles used is shown in Fig. 4; it
consists of a hollow tube, on which a wharve of the shape shewn in
Drawing is fixed by means of a set screw in the way shewn in Drawing.
The tube has a collar on the top. The spindle on which the cop is
formed also has a collar which comes face to face with collar of tube;
the spindle is loose in the tube and may be lifted out; it is turned or
carried round by the friction of the two collars together. The spindle in
being raised and lowered by the spindle box passes through the hollow
bush (No. 1, Fig. 4); this bush is fixed in the rail (No. 9, Fig. 1) by a
set screw at the back of the rail. A flyer of the form shewn, No. 2, in
Fig. 4, revolves on the top part of the bush, and winds or lays the yara
on the spindle.

page_text: Fig. 3 shews the form of spindle roller. It has two speeds on it,
the larger speed being for driving the spindle, and the smaller speed for
driving the flyer; it is fixed at the back of the machine, and drives the
spindle and flyer by means of . bands. passing from it to them. The cop
and spindle are shewn in Fig. 4 passing through the bush.
The cone is shewn with only one nose or projection, but I claim for
it having 1, 2, 3, 4, or more noses as may be found to be required.
Also for the rod carrying the guide wires I claim it as revolving as
well as partly revolving. In the case of its revolving the long bent
wires are dispensed with, and in their place grooves are cut in the rod
in which the yarn runs, and it is made to rise and fall to serve the same
purpose as the wires.
In particular I claim for the cone and lever motion, the guide wire
rod and wires, the spindle box, spindle and flyer, and driving roller for
spindle and flyer.
In witness whereof, I, the said Thomas Spencer, have hereunto
set my hand and seal, this Fourteenth day of December, in
the year of our Lord One thousand eight hundred and sixty-
eight.
