IMPROVE- MENTS IN MULES FOR SPINNING
Year: 1871

page_text: LETTERS PATENT to Thomas Whitehead Parker, of Roach, in the
County of Lancaster, Cotton Spinner, and James Greenwood, of
the same Place, Spinning Master, for the Invention of "IMPROVE-
MENTS IN MULES FOR SPINNING."
Scaled the 13th June 1871, and dated the 22nd April 1871.
PROVISIONAL SPECIFICATION left by the said Thomas Whitehead
Parker and James Greenwood at the Office of the Commissioners
of Patents, with their Petition, on the 22nd April 1871.
We, THOMAS WHITEHEAD PARKER, of Roach, in the County of
Lancaster, Cotton Spinner, and JAMES GREENWOOD, of the same Place,
Spinning Master, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MULES FOR SPINNING," to be as follows:-
Our Invention relates to the winding apparatus for self-acting
spinning mules, in which we obtain a simple and more direct motion
for winding than has ever been obtained before.
We dispense with the objectionable quadrant, chains, springs, catch,

page_text: We attach to the faller rod a lever or other equivalent, to the end of
which is attached a vertical rod, at the bottom end of which rod is a
friction roller which rolls freely on the surface of an horizontal fulcrum
lever fixed on the floor by a bracket and fulcrum pin. This horizontal
fulcrum lever is acted upon by the stripping faller lever and vertical 5
rod attached to the same.
To the inner end of this lever we fix a chain or other equivalent,
which chain or other equivalent is attached likewise to the " backing
off" friction lever passing round suitable pullies. Inside such friction
lever we attach a spring or other equivalent for the purpose of keeping 1
such lever to its work, such work being to back off and to regulate the
winding, which winding will be accomplished by the driving strap being
partially on the fast pulley.
By shaping our horizontal fulcrum lever to suit we can cross our
yarn in winding several times in each stretch.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Whitehead Parker and James Greenwood
in the Great Seal Patent Office on the 18th October 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
WHITEHEAD PARKER, of Roach, in the County of Lancaster, Cotton 2
Spinner, and JAMES GREENWOOD, of the same Place, Spinning Master,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of April, in the
year of our Lord One thousand eight hundred and seventy-one, in the 2
thirty-fourth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Thomas Whitehead Parker.
and James Greenwood, Her special licence that we, the said Thomas
Whitehead Parker and James Greenwood, our executors, administra-
tors, and assigns, or such others as we, the said Thomas Whitehead 3
Parker and James Greenwood, 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

page_text: Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN MULES FOR SPINNING,” upon
the condition (amongst others) that we, the said Thomas Whitehead
Parker and James Greenwood, our executors or administrators, by an
instrument in writing under our, or their, or one of their hands and
scals, 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 Whitehead Parker and
James Greenwood, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, referenco
being had to the accompanying Drawings, in the several Figures
of which similar parts are marked with corresponding letters of
reference:
Fig. 1 is a side view of our apparatus; Fig. 2 is an end view of the
same.
A is the mule carriage; B, headstock; C, C, driving pullies; D, D,
faller rods; E, the backing-off friction lever, which is lengthened to
recieve the chain F or equivalent, and spring G or equivalent at N
and H, the other end of such spring to a bracket I; J is an horizontal
fulcrum lever secured to the floor or frame of the headstock, as con-
venience may dictate; one end of this lever works in a fulcrum
bracket L; to the other end of this fulcrum lever is attached the chain
or other equivalent F, which passes over pulley M, and secured to
backing-off friction lever at N by a regulating screw o. On to the front
faller rod D is fixed a crank-shaped lever P or equivalent connected by
joint a to vertical rod R, at the bottom of which rod is two friction
rollers band. c, which run freely on the top and bottom sides of hori-
zontal fulcrum lever J; this rod is kept in a vertical position by
bracket & bolted to carriage A. The strap fork i is worked by the
cam shaft S.
This strap we drive partialy on to the fast pulley by a
cam motion e on the cam shaft. The "quadrant, chains, and other
appliancies," we thereby entirely dispense with.
'
Its action is as follows:-When the carriage is out, and the cam shaft
changes to draw the carriage up, it drives the driving strap partialy on

page_text: to the fast pully, and sets the backing-off friction at liberty, at the
same time the vertical shaft R falls with its friction roller 6 on to
fulcrum lever J. The winding is then regulated by the rising and
falling of the striping faller on front rod D. The action of such striping
faller through crank lever P, vertical rod R, on to horizontal fulcrum
lever J, thus through chain F acts on backing-off friction lever E as
required, and regulates the winding.
Having fully described our Invention and the way in which we work
it, we may say in conclusion that we do not confine ourselves to the
precise details we have had occasion to describe and refer to, as many
variations may be made in detail without departing from the principle
or main features of the Invention secured to us herein; but what we
claim as our Invention is,-
First. The crank lever P, rod R, lever J, chain F, lengthened friction
lever E and spring G, or equivalents, for the purposes hercin described, 1
substantialy as set forth and illustrated.
Second. The cam motion e and the working the driving band
partialy on to the fast pully, for the purposes herein described and
illustrated.
Third. The method of winding as herein, and dispensing with the 2
quadrant chains and other appliances, substantialy as herein described
and illustrated.
In witness whereof, we, the said Thomas Whitehead Parker and
James Greenwood, have hereunto set our hands and seals, this
Twelfth day of October, in the year of our Lord One thousand 2
eight hundred and seventy-one.
