BANNERLO
"
PROVISIONAL SPECIFICATION left by the said George Wrigley and
Samuel Morris at the Office of the Commissioners of Patents, with their
Petition, on the 13th February 1863.
We, GEORGE WRIGLEY, of the Firm of Messieurs Cryer and Lees, of
Dukinfield, in the County of Chester, Machine Makers, and SAMUEL MORRIS,
of the same Place, Mechanic, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINES FOR SPINNING AND DOUBLING," to be
as follows:-
Our Invention consists in an improved mode of driving the cam shafts of
self-acting mules. It has heretofore been customary in Roberts' self-actors,
patented 29th March 1825, and numbered 5138, to drive the cam shaft from
the twist shaft by means of a friction pulley acting on a pulley in which four
recesses are made; now our improvements consist in driving the cam shaft in
the following manner:-On the cam shaft is a pinion which is driven from the
backing-off wheel, or any other convenient wheel on the headstock, to the boss
of this pinion is fixed a ratchet wheel, and on this boss is mounted a lever with

page_text: four catches on its centre. On the cam shaft is a disk with the catch taking
into the ratchet wheel; to the lever is jointed a vertical rod which bears upon
a horizontal bar with three inclines. When the carriage is out and the first
change is required, the horizontal bar is liberated by a stud on the carriage
lifting a catch; the second change is performed by the twist finger liberating
the bar; the third is performed by the locking of the faller, and the fourth
when the carriage is in by an incline on the carriage raising the vertical rod
above referred to. At every change the lever is moved to liberate the catch
on the disk, thereby allowing it to drop into gear with the ratchet wheel. The
cam shaft is held in position after every change by a spring taking into
notches in a disk. The above details may be considerably varied.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Wrigley and Samuel Morris in the Great Seal
Patent Office on the 13th August 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
WRIGLEY, of the Firm of Messieurs Cryer and Lees, of Dukinfield, in the
County of Chester, Machine Makers, and SAMUEL MORRIS, of the same Place,
Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of February, in the year of our Lord
One thousand eight-hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said George Wrigley and Samuel Morris, Her special license that we, the
said George Wrigley and Samuel Morris, our executors, administrators, and
assigns, or such others as we, the said George Wrigley and Samuel Morris,
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 MACHINES FOR
SPINNING AND DOUBLING," upon the condition (amongst others) that we, the
said George Wrigley and Samuel Morris, our executors or administrators, by
an instrument in writing under our, or their, or one of our or 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

page_text: calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said George Wrigley and Samuel Morris,
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 (that is to say):-
Our Invention consists in an improved mode of driving the cam shafts of
self-acting mules. It has heretofore been customary in the mules known as
Roberts' self-actors, to drive the cam shaft from the twist shaft by means of a
friction pulley, in which four recesses are made; now our improvements
consist in an improved mode of driving the cam shaft by gearing, which will
be fully understood and readily carried into effect by reference to the accom-
panying Sheet of Drawings, and to the figures and letters marked thereon.
Figure 1 is an elevation of part of the headstock of a self-acting mule to
which our improvements are applied; Figure 2 is a plan of the same.
a is the rim shaft of the mule, and 6 the backing-off wheel, to which is
fixed the internal friction pulley fitting on the usual friction cone c; d is the
cam shaft, to which is fixed the cam e for working the lever of the backing-off
wheel 6 and the escapement disc f. All these parts and the others requisite
to complete the mule, which are not shewn, and not particularly referred
to hereafter, are made in the usual manner.
Our improved mode of driving the cam shaft may be performed. in the
following manner :-The backing-off wheel 6 gears into the carrier pinion g,
which gears into another carrier pinion h gearing into the pinion i loose on
the cam shaft d; to the boss of the pinion i is fixed the ratchet wheel j, this
boss passes through the lever or fixing k, which is secured to the bracket 1,
in which are rivetted the studs for the carrier pinions 9 and h; to the eye or
centre of the lever or fixing k are fixed four projections, the object of which
will be explained hereafter. To the cam shaft d is fixed the disc m, in which
is a stud for the catch n, taking when required into the teeth of the ratchet
wheel j; the catch n is acted upon by the spring o, which is also fixed to the
disc m.
The mode of operation is as follows:-The parts are shewn in the positions
they occupy when the carriage is near the roller beam. As soon as the
escapement lever forming part of the mule known as Roberts' self-actor, has
liberated the escapement disc f, the usual cam spring acting on one of the
studs projecting from the back of the escapement disc f moves the cam shaft
round for a very small portion of a revolution, or sufficiently to release the
catch n from the projection on the boss of the lever or fixing k, on which it is

page_text: now shewn; the catch n then drops into gear with the ratchet wheel j, the
backing-off wheel 6 then gives motion to the pinion i (through the carrier
pinions g and h) and ratchet wheel j, which acting on the catch n cause the
disc m and cam shaft d to rotate for one-fourth of a revolution, or until the
catch n is lifted out of gear with the ratchet wheel j by the projection k¹ of
the lever or fixing k; the successive changes in the position of the cam shaft
are performed in a similar manner, each quarter revolution bringing the
If
catch n on one of the four projections on the boss of the lever or fixing k.
it should be requisite to change the position of the cam shaft by hand the
operative acting on the sliding bar p draws the pinion h out of gear with the
pinion i, thus setting the cam shaft at liberty.
Our improvements may be modified by connecting the lever or fixing k with
four projections, above referred to, to a vertical rod bearing upon a horizontal
bar with three inclines. When the carriage is out and the first change is
required, the horizontal bar is liberated by a stud on the carriage lifting a
catch; the second change is performed by the twist finger liberating the bar;
the third is performed by the locking of the faller, and the fourth when the
carriage is in by an iucline on the carriage raising the vertical rod above
referred to. At every change the lever is moved to liberate the catch n on
the disc m, thereby allowing it to drop into gear with the ratchet wheel j.
The cam shaft d is held in position after every change by a spring taking into
notches in a disc.
Having thus stated the nature of our Invention and described a convenient
mode of performing the same, we wish it to be understood that we do not
limit ourselves to the details given, as the same may be considerably varied or
modified; we therefore claim as our Invention the improved mode of driving
the cam shaft by toothed gearing, and the arrangement of p: 's for con-
necting and disconnecting the pinion i to and from the cam s., as shewn
and described.
In witness whereof, I, the said George Wrigley, have hereunto set my
hand and seal, this Tenth day of August, in the year of our Lord Oue
thousand eight hundred and sixty-three.
GEORGE WRIGLEY. (L.S.)
