IMPROVEMENTS IN SELF- ACTING MULES FOR SPINNING COTTON AND OTHER FIBROUS MATERIALS
Year: 1864

page_text: LETTERS, PATENT to Joseph Cheetham, of Oldham, in the County of
Lancaster, Cotton Spinner, for the Invention of "IMPROVEMENTS IN SELF-
ACTING MULES FOR SPINNING COTTON AND OTHER FIBROUS MATERIALS."
PROVISIONAL SPECIFICATION left by the said Joseph Cheetham at:
the Office of the Commissioners of Patents, with his Petition, on the..
29th August 1864.
I, JOSEPH CHEETHAM, of Oldham, in the County of Lancaster, Cotton
Spinner, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SELF-ACTING MULES POR SPINNING COTTON AND OTHER FIBROUS MATERIALS," to
be as follows:-
This Invention consists of an improved arrangment for relieving the under
faller and enabling it to be in contact with the yarn, forming thereby a tighter
and more perfect cop than has been hitherto made.
Instead of connecting the two fallers by a chain and guide pulley, which
method only allowed of one faller to take what the other gave, I make the
fallers independent of each other at the time of winding on, and hold them
together only when the carriage is coming out. On the under faller shaft
I fix a lever having at the end a bowl or projection which can be adjusted as
required, and to the top faller shaft. I fix another lever, bent at the end, so

page_text: that when the carriage is coming out it can be in contact with the aforesaid
bowl or projection and hold the under faller in its proper position. The
instant the top faller is moving down, the bent end is relieved from the bowl
or projection and allows the two fallers to be independent of each other.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Cheetham in the Great Seal Patent Office on the
25th February 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
CHEETHAM, of Oldham, in the County of Lancaster, Cotton Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of August, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Joseph Cheetham, Her special license that. I, the said Joseph
Cheetham, my executors, administrators, and assigns, or such others as I,
the said Joseph Cheetham, my 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 "IM-
PROVEMENTS IN. SELF-ACTING MULES FOR SPINNING COTTON AND OTHER FIBROUS
MATERIALS," upon the condition (amongst others) that I, the said Joseph
Cheetham, my executors, or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, 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 I, the said Joseph Cheetham, do hereby declare
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 (that is to say) :-
This Invention consists of an improved arrangement for relieving the under
faller and enabling it to be in contact with the yarn for the purpose of forming
tighter and more perfect cops than have been hitherto made.

page_text: Instead of connecting the two fallers by a chain and guide pulley, which
method only allowed one faller to take what the other gave, I make the fallers
ndependent of each other at the time of winding on and hold them together
only when the carriage is coming out. On the under faller shaft I fix a lever
having at the end a bowl or projection which can be adjusted as required,
and to the top faller shaft I fix another lever, bent at the end, so that when
the carriage is coming out it can be in contact with the aforesaid bowl or
projection and hold the under faller in its proper position. The instant the
top faller is moving down, the bent end is relieved from the bowl or projection
and allows the two fallers to be independent of each other.
These improvements will be clearly understood by referring to the figures
and letters on the accompanying Sheet of Drawings, in which Fig. 1 is an
end elevation of the carriage and fallers and cross section of the rollers of a
self-acting mule; Fig. 2, an end view showing my additional levers connected
to the faller shafts; and Figs. 3 and 4 are end and front views of the addi-
tional levers, drawn about full size...
In the several Figures a represents the under or counter faller shaft; b, the
under or counter faller levers; c, the top or copping faller shaft; and d, the
top or copping faller levers. To the under faller shaft a I fix the lever e,
having at the end the bowl f, and to the top faller shaft c I fix the lever h,
bent or curved at the end; and instead of connecting the two fallers by a
chain and guide pulley, I make them independent of each other for enabling
the under faller to be raised and pressed against the yarns, independently of
the descent of the top faller, by means of the ordinary chain i, chain wheel k,
and weights 1. When the carriage is coming out for spinning, the top faller is
prevented from descending, and the lever h from coming forwards, by means
of a number of springs, one of which is shown at m, and the under faller is
prevented from rising to the yarns by the bowlf being in contact with the
bottom of the lever h, as shown in Fig. 2, and by the full lines in Fig. 3; but
when, during the backing off, the top faller moves down, the lever h comes
forward at the same time and releases the bowl f and lever e, as shown by the
dotted lines in Fig. 3, so that when the carriage is being put up and the
yarn is being wound on the spindles, the top faller can be pressed on the yarns
by the shaper, perfectly independent of the under faller, and at the same time
the under faller can be pressed up to the yarns by means of the weights inde-
pendent of the top faller; and as the under faller can press against the yarns
in any position of the top faller, it is evident that the yarn can be wound on
more tightly and perfectly than when the movement of the under faller
depends upon the-movement of the top faller. When the winding on is com-
÷
'

page_text: pleted and the top faller released from the shaper, the springs 'm, Fig. 2, raise
the top faller to its highest position, and also place the lever h in its most
backward position, and at the same time the curved part o of the lever p,
Fig. 1, is pressed down by the bowl q working on a stud fixed to the roller
platform r, so as to overcome the weights and pull the chains and depress
the under faller and bring forward the lever e for enabling the weights 1 to
press the bowlf in contact with the bottom of the lever h, when the part o is
released from the bowl q by the carriage coming out, the said weights main-
taining the contact of the bowl and lever, and holding the fallers until the
next backing off is commenced.
Having now described. the nature and particulars of my said Invention, and
the manner in which the same is to be performed, I desire it to be understood
that I claim the application to the under faller shaft of the lever e with its
bowl or projection, and to the top faller shaft of the lever h for enabling the
fallers to be independent of each other whilst the yarns are being wound on
the spindles, and for steadily holding the fallers out of reach of the yarns
during the process of spinning, as all such improvements are herein described
and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said Joseph Cheetham, have hereunto set my
hand and seal, this Twenty-first day of February, in the year of our.
Lord One thousand eight hundred and sixty-five.
Signed, sealed, and delivered by the
within-named Joseph Cheetham,.
