IMPROVEMENTS IN MULES FOR SPINNING AND DOUBLING
Year: 1862

page_text: LETTERS PATENT to Thomas Greenwood and James Schofield, of Roch-
dale, in the County of Lancaster, Machine Makers, for the Invention
PROVISIONAL SPECIFICATION left by the said Thomas Greenwood and
James Schofield at the Office of the Commissioners of Patents, with
their Petition, on the 7th November 1862.
We, THOMAS GREENWOOD and JAMES SCHOFIELD, of Rochdale, in the
County of Lancaster, Machine Makers, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MULES FOR SPINNING AND DOUBLING," to
be as follows:-
Our Invention relates, firstly, to the winding-on motion, and consists in a
method of giving motion to the "radial arm "thereof. For this purpose we
adapt a jointed lever to the carriage, which lever being capable of turning
upon a centre at its other end, assumes different angles as the carriage runs
in and out, and imparts motion to the radial arm by means of a connecting
rod. In the said lever we form two slots to admit of the above-mentioned
variations in position, and we use the axis of the radial arm for its centre of
motion.
Another part of our Invention relates to a shaping apparatus. To the
carriage front we adapt a shaper mounted so as to slide úpon a rod or rods
carried by a bracket. This shaper is provided with a fork, which embraces a

page_text: rail set at an angle to the carriage, and it is thus caused to travel to and fro.
To the above-mentioned bracket is jointed a lever carrying a roller, which
rests upon the shaper, and the faller leg rests upon the said lever.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Greenwood and James Schofield in the Great Seal
Patent Office on the 7th May 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wе, THOMAS
GREENWOOD and JAMES SCHOFIELD, of Rochdale, in the County of Lancaster,
Machine Makers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of November, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Thomas Greenwood and James Schofield, Her special license,
that we, the said Thomas Greenwood and James Schofield, our executors,
administrators, and assigns, or such others as we, the said Thomas Greenwood
and James Schofield, our executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN MULES FOR SPINNING AND DOUBLING," upon the condition,
amongst others, that we, the said Thomas Greenwood and James Schofield,
by an instrument in writing under our hands and seals, or under the hand
and seal of one of us, should particularly, describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said Thomas Greenwood and James Scho-
field, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement and accompanying Drawings, that is
to say:-
The first part of our Invention relates to the winding-on motion of mules,
and is shown at Figure 1 of the accompanying Drawings, which represents the

page_text: arrangement in plan view, the radial arm and regulating screw being placed

shewn at a; to which is jointed a bar b.
which embraces the stud d upon which the radial arm e turns. To the
outward end of the radial arm is jointed a rod f, the other end of which is
furnished with a pin g, situate within a sloth formed in the bar b. As the
carriage a runs to and fro the slot c will traverse the stud d, while at the
same time the pin g will traverse the other slot h, and the radial arm will
therefore be caused to turn upon its centre, acting upon the winding-on
chain i as usual. The regulating screw is shewn at k, upon which is a bevil
pinion taking into another m, to which motion is communicated in any
ordinary manner through the medium of the band n. The above-described
arrangement for giving motion to the radial arm affords a considerable amount
of variation, the extent of which may be determined by shifting the pin g in
its slot so as to alter the relative angles of the connecting parts.
Fig. 2 represents in plan view a modification of the above-described
improvement. In this instance the bar 6 is part of the radial arm e, and is
provided with a slot h, which embraces a pin o attached to the carriage a. As
the carriage runs to and fro, therefore, this pin traverses the slot h, and
imparts the required motion to the radial arm. At p is a rail upon which a
roller 9, carried by the radial arm runs. The regulating screw k is, as before,
turned by bevil pinions l, m, and at n is the winding-on chain.
Another part of our Invention refers to the shaping apparatus, and is
shewn in two views at Figs. 3 and 4, and in the Diagram, Fig. 5. The mule
front is shewn at 1, to. which are attached two rods 2, 2, furnished with
sliding brackets 3, to which is affixed a plate 4; behind this plate is another.
plate 5, capable of sliding thereon, it being mounted in guides formed in the
brackets 3, 3. At 6 is the shaper plate, mounted so as to slide upward. and
downward in guides, also formed in the brackets 3, and provided with two pro-
jecting pins 7, 7, situate within angular slots formed in the plate 5; by these
slots, therefore, the shaper plate is maintained at the required elevation, but
capable of falling by the sliding sideways of the slots, as hereafter to be
described. Upon the front plate 4 are projections 8, 8, which carry a screw 9
working in nut 10, fixed to the plate 5. At the end of this screw is a
ratchet wheel 11, capable of being driven by a click 12, so as to cause the
said screw to revolve, and thereby traverse the nut. It will be seen by the
above description that the shaper plate 6 and middle plate 5 are carried by the
front plate 4, and that the whole of these parts, together with the screw 9,
are capable of sliding bodily upon the rods 2, while at the same time an inde-

page_text: pendent traversing motion may be communicated to the plate 5 by the
turning of the screw 9. To the front plate is fixed a fork 13, within which is
a rod 14, carried by the mule carriage, as shewn in the Diagram, Fig. 5.
This rod is placed at an angle, as seen in that Fig., and when, therefore, the
carriage runs in and out, the said angular bar acting upon the fork 13, causes
the bodily motion of the shaper, and other two plates above mentioned.
At 15 is a roller resting upon the shaper 6, and carried by a bar 16, mounted
so as to be capable of sliding upward and downward in guides 17 attached
to the mule front; this bar is connected by the usual means to the fallers.
The operation is as follows:-At the commencement of forming the cop u
the shaper is at its greatest elevation, the pins 7 being within the upper
parts of the slots. As the carriage runs out the plate 4 will be slidden on the
rods 2 by the bar 14, as above described, carrying with it the shaper 6, and:
thus regulating the height of the faller roller 15, it being slidden back again
by the return motion of the carriage; but in addition to this movement, the
lever 20 which carries the click 12, will at every stretch arrive in contact with
a fixed part, so as to cause the screw 9 to turn, by which means the plate 5
will be slidden in its guides, so as to carry the slots forward and permit the
shaper plate 6. to fall through a short distance, as is well understood. The
slot at the right-hand side of Fig. 3 is placed at a different angle from that
shewn at the other side, so as to allow the end of the shaper plate, which it
supports, to fall quicker than the other end thereof.
+
Having thus described and ascertained the nature of our said Invention,
and the manner of carrying the same into effect, I desire it to be understood,
that we claim as secured to us under the above in part recited Letters
Patent,-
Firstly, the means of giving motion to the radial arm, as illustrated at
Figs. 1 and 2.
Secondly, the shaping apparatus, illustrated by reference to Figs. 3, 4,
and 5.
In witness whereof, I, the said Thomas Greenwood have hereunto set
my hand and seal, this Sixth day of May, in the year of our Lord
One thousand eight hundred and sixty-three.
