lawfully might make, use, exercise, and vend, within England. Wales, and the
Town of Bewick-upon-Tweed, our Invention of "IMPROVEMENTS IN CERTAIN
PARTS OF MACHINERY USED IN THE PREPARATION FOR SPINNING, AND IN THE
SPINNING AND DOUBLING OF COTTON, WOOL, AND OTHER FIBROUS SUBSTANCES,
in which said Letters Patent 15 contained a proviso, obliging us, the said
Benjamin Fothergill and Richard Johnson, by a instrument in writing under
our hands and seals, or under the hand and seal of one of us. particularly to
describe and ascertain the nature of our said Invention, and in what manner
the same is to be performed. and to cause the same to be enrolled in Hei
Majesty's High Court of Chancery within six calendar months next and imme-

page_text: diately after the date of the sand iccited Letters Patent, as in and by the said
Letters Patent, reference being thereunto had, will more fully and at large
appear
NOW KNOW YE, that in compliance with the said proviso, we. the said
Benjamin Fothergill and Richard Johnson, do hereby declare -the-nature of
our said Invention to consist,-
Fust, in an improved combination of machinery to be applied to that part
of preparation or spinning machines which regulates the winding on to the
spindle of the 10vings or yarn, in adaptation to the gradually varying form and
inci casing diameter of the bobbin or cop
Secondly in an improved combination of machinery, whereby the whole of
the spindles m each such machine are diven by a continuous shaft, which
works in the carriage under the spindles.
And, lastly, in an improved combination of machinery for cleaning the tops
of mule carriages, whilst they are in operation, by 1olleis, which are made to 1
descend upon the cannage top as it runs out from the drawing rollers as
often only as shall be required.
And in further compliance with the said proviso in the said Letters Patent
contained, we do hereby further state the manner-in which-the-said.Invention
is to be carried into effect, reference being had to the Drawings annexed, and
to the figures and letters marked thereon, that is to say -
DESCRIPTION OF THE DRAWINGS
In Sheet 1, Fig. 1 represents a side elevation of part of a self-acting mule
headstock and parts of a mule cauage with parts of our improvements
attached thereto, Fig 2 represents in plau, a part of the same headstock and
a part of the carriage. Fig 3 represents. In plan. a part of the headstock
known by the name of the square, shewing our improved mode of during the
spindles by one continuous shaft
In Sheet 2. Fig 4 represents a side elevation of one of the supports of the
roller beam called a sampson, also a section of the roller beam, 1ollers, and
parts of the carnage, with our improved cleaning apparatus attached, Fig 5
represents a plan of parts of the machinery shewn in Fig 4: Similai letters
and figures denote similar parts in all the Drawings. and the scale of the
Diawings is three inches to one foot
In Fig 1A is part of the framing of a mule headstock, B is part of the s
carriage, is a radial arm attached in the ordinary manner to the fiaming of the
headstock Pior to our improvements this arm formed, one side of a quadrant.
which quadrant had teeth upon its periphery, into which the teeth of a pimou

passed over by the caillage Thus pinion and toothed quadiant we have dis-
pensed with, and in their place we use d, a dium, 1ound which the chun c is
wound, and to which it is attached at one end, and the other end of this chain
e is attached to a hook f, which hook is united to the nut 9 by a pin passing
through it and the nut The nut is adjustable on the screw h which is attached
to the radial aim by two cannes 1, 2, a cord or band may be used instead
of the chain e. is a spring, agamst, which the radial aim is dawn by the
dium d when the carriage is at the greatest distance from the drawing rollers,
and which spring 7 keeps in a state of tension the chain e, when the winding
on, commences, each time the caninge uns m. By means of the sciew and
nut g,.the hook f may be 1aised or lowered, so as to increase or decrease, as
may be required, the arc traversed by it, and may be there fixed by the lock
nut k. By this anangement, for working the top of the aim e through the
arc of a cucle, the speed of it as the carnage uns in is not uniform, as here-
tofore, but variable, such variation being calculated to benefit the winding on
of the yan. In Fig. 3 is shewn our improved combination of machmety for
duving mule spindles, which consists in having one continuous shaft 7 passing
over the square of the headstock and underneath the lium axes. as shewn
in Fig. 1, to, the extremities of the carriage. We have not described the
other parts here shown, as they are well known, and have been employed m
various positions to effect the same purpose of backing off and winding on, as
they do in this machine. The shaft is duiven from the iim band in the usual
way, in the duection of the arrow. In Figs 1 and 2, m, m, are intended to
represent bevil wheels, by which the diums are duven

for the purpose of taking up lint or other waste from the top of the carnage.
which rollers are supported at each end by a pivot passing from them into a
hole in the boss of the lever o At the other end of these leveis o is another
boss, through which a shaft p passes and extends the length of the mule These
levels are fixed to the shaft p by set screws The shaft pis supported by
bearings 9, one of such bearings being fixed to each sampson aim and one to
each of the outer frames 7 is another lever, fixed to the shaft p by a boss
and set screw; to the other end of this level is suspended a rod, the lower
extremity of which rod is attached by a pin to a bell-ci anked levert this lever
t is supported on the same stud as that which carries the ratchet wheel it
the bottom of the lower arın of the hell-crank lever the end of a rod vis
attached the other end of which rod is supported by an upright lever (sec
Fig 4) which lever works on a stud fixed to the camera. which is bolted to
To

fixed to a carrier y, which is bolted to one of the sampsons. On the same stud
works an arm, which aim carries a catch which takes into the ratchet wheel,
the lower side of this aim forins-an inclined plane.. On the back of the
calage is fixed a bracket 1, which carries a fiction roller 2 Fioni a stud
on the upper end of the carrier y is suspended a weighted catch 3, with a
shoulder 4 on it, for the purpose of holding the rollers n off the carriage when
there is no lint or dut to be removed. On the weight 3 is also a project,
against which a stud 6 in one arm of the ratchet wheel acts, and forces the
weight back, so as to allow the rollers to fall on the top of the camage when
not supported. When the cannage runs out, it strikes against the upright level
w. andth ereby diaws up the rollers n, n, by the rods and s. the bell-ci ank
lever t, and the levels r and o. and the shaft p. and the rollers are held up by
the notch 4 in the weight catching the pin in the bell-crank t, which it holds
in that position till the ratchet wheel has revolved and forced the catch back
by a pin in one of its arms. The rollers fall on the top of the cannage before
it commences to run out, and although one tooth of the ratchet wheel is
moved at a time¬n-the-machine-shewn by the Diawing, whereby the rollers
fall on the top of the carnage and clean it once only at every twentieth stictch,
yet it is evident by varying the number of teeth in the ratchet wheel, or
increasing the action of the catch, so as at each running in to cause it to
move the ratchet wheel a distance of two or more teeth, the rollers may be
made to fall on and clean the top of the carnage more or less ficquently
Having now described the nature of our said Invention, and the manner we
carry it into effect, we hereby claim as our Invention,―
First, the screw h, the nut g, the hook f. the chain e, and the dium d,
combined and ananged as herem-before described, for working the radial arm
of a mule headstock, as substitutes for the toothed quadiant and pinion here-
tofore used for that purpose.
Secondly, the mechanism in the square, combined and arranged as herem-
before described, and exhibited in Sheet 1, Figs 2 and 3, for communicating
motion from the headstock to the continuous shaft which dives the dium by
geening
And, lastly, the machinery for cleaning the top of the mule carriage, com-
bined and arranged as herein-before described, and exhibited in Sheet 2,
Figs 4 and 5
And this our Invention being to the best of our knowledge and belief,
entuely new, and never before used within that part of He said Majesty's
United Kingdom of Great Britain and Ireland called England He

page_text: Dominion of Wales, and Town of Berwick-upon-Tweed, we do hereby respec-
tively declare this to be our Specification of the same, and that we venly
believe this our Specification doth comply in all respects fully and without
escive or disguise with the proviso in the said herein-before in part recited
Letters Patent contained, wherefore we do hereby claim to maintam exclusive
night and privilege to the said Invention
In witness whereof, we, the said Benjamin Fothergill and Richard
Johnson, have hereunto set our hands and scals, this Fourteenth day
of December, in the year of our Lord One thousand eight hundred
and forty Six.
