IMPROVEMENTS IN MULES FOR SPINNING
Year: 1871

page_text: LETTERS PATENT to John Mullin, of Oldham, in the County of
Lancaster, Spinning Master, for the Invention of "IMPROVEMENTS
IN MULES FOR SPINNING."
Sealed the 21st November 1871, and dated the 20th June 1871.
PROVISIONAL SPECIFICATION left by the said John Mullin at the
Office of the Commissioners of Patents, with his Petition, on the
20th June 1871.
I, JOHN MULLIN, of Oldham, in the County of Lancaster, Spinning
Master, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN MULES FOR SPINNING," to be as follows:-
My Invention consists in certain improvements "in" or addition to
the self-acting spinning mule whereby a much harder cop may be

page_text: "
made with a very tight nose, "so much so that a very considerable
per-centage more yarn may be put on the same sized cop. This I effect
by the following application:-
On the quadrant or floor near such quadrant I fix a frame, and in
such frame I work a screw. Longitudinally with such frame and screw
is an inclined plate that is made to slide on such frame, this plate is
worked in and out by means of the aforesaid screw in combination with
ratchet wheel motion or other equivalent. On the square of the mule
carriage I fix a bracket with slots, into which I work a loose lever, this
lever as the carriage goes up is raised by the inclined plate beforc
mentioned, the top end comes in contact with the winding chain,
increases the speed of the winding barrel, thus taking up the yarn
much quicker at the cop nose. Thus by making a harder cop nose a
much better cop is built than by the ordinary means. The screw and
incline is gradually acted upon by ratchet motion or other equivalent
to follow the build of the cop and is self-acting.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Mullin in the Great Seal Patent Office on
the 20th December 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MULLIN, of Oldham, in the County of Lancaster, Spinning Master,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of June, in the year of

that I, the said John Mullin, my executors, administrators, and assigns,
or such others as I, the said. John Mullin, my executors, adminis-

Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MULES FOR
SPINNING," upon the condition (amongst others) that I, the said John
Mullin, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
5 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 I, the said John Mullin, do hereby declare
O the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement :-
1
My Invention relates to self-acting or hand spinning mules, and
consists in certain additions to, and improvements in such machinery
5 wereby a much harder cop with a very tight nose can be made, con-
sequently 'more yarn wound on a cop of the same size. And in order
that the same may be better understood I annex hereunto a Sheet of.
Drawings, in the several Figures of which similar parts are marked by
corresponding letters of reference.
Fig. 1 is a side view of my apparatus shewing its action on the winding
chain; Fig. 2 is an end view of the same; Fig. 3 is a bracket with
pendent catch finger tappet P on a larger scale than the other Figures.
A in Fig. 1 is a quadrant radius arm in ordinary use; B, the winding
chain; C, the barrel; D, D, floor line; E, a frame fixed on the floor
into which works screw longitudinally with such frame.. On this screw
I work a concave or other shaped incline plate G, sliding on such
frame; this incline plate is worked in and out by the aforesaid screw
acted upon by ratchet wheel H by catch finger tappet I. This finger
is hung to the lever J by pin K, and swivels freely on the screw
shaft L, the other end of lever J at M is connected to a bent lever
plate N, or equivalent, which is acted upon by the pendent finger P,
which gives way as the mule comes out, but as the mule goes in it
being supported at the back by the bracket o at a in Figs. 2 and 3,
such finger deflects lever N, thereby giving motion to ratchet wheel H
one or more teeth by the catch finger I. The finger Pliaving passed

for the purposes herein set forth.
In witness whereof, I, the said John Mullin, have hereunto set
my hand and seal, this Sixteenth day of December, in the
year of our Lord One thousand eight hundred and seventy-
one.
