"
And whereas I have been advised that one portion of the Invention
claimed in the said Specification was not of such novelty at the date of
the Patent as to render it desirable to retain a claim for that portion, I
am desirous of disclaiming, and hereby disclaim the second head of the
said Invention, and I further make such alterations as the striking out
of so much, of the Specification may render necessary (that is to say)
I strike out from page 3 of the printed copy of the Specification the
lines 12 to 17 inclusive. Also line 1 in page 5, and I cancel Figures
2 and 3 of the Drawings. I also alter the words " Thirdly and
Fourthly" which occur in pages 3 and 5, to "Secondly" and
Thirdly," respectively, when the Specification will stand as follows: -
Our Invention relates, firstly, to the differential motion of slubbing or
roving frames, and is shewn_at_Fig. 1. of the accompanying Drawings.
The main shaft of the said motion is at a, supported by the boss b,
which according to the usual arrangement terminates at the pinion c.
According to our Invention, however, we extend it to the point d, and
mount the wheels c, e, f, thereon instead of upon the shaft as usually
practised. The arrangement as regards the other parts of the apparatus
is that in ordinary use.
6
Secondly. Our Invention relates to a method of balancing the lifting
rail of slubbing or roving frames, which arrangement is shewn at Fig. 4.
The lifting rail a, is raised in the ordinary manner by the pinion b, and
rack c, but it is also provided with another rack d, in gear with which is
a pinion e, mounted upon a stud, which also carries a pulley f. To this
pulley a chain d is attached, which after passing over a guide pulley h,
carries the counterbalance weight i.
Thirdly. Our Invention relates to such machines as the "mule," and
consists in causing the roving to be delivered by the rollers in a variable
degree as the carriage runs in, such variation taking place according to the
increasing size of the cop. Fig. 5 is a partial view of a mule with the im-
provement adapted. The roller beam is shewn at a, the rollers of which
receive rotatory motion from the wheel b, driven by the pinion c; this
pinion is carried by a lever , which turns upon a centre nt e, and it is
provided on its upper part with a clutch f.taking into a counterpart
within the pulley. g. Upon the lever therefore being turned upward

page_text: rollers is effected.
The following is an arrangement we adopt :-Upon the lever is a
projecting pin situate within a slot formed in an arm i. This arm
extends from a bar k, which is mounted upon a screw n, passing
through a nut o, which extends from a boss p, mounted so as to slide
in guides formed upon the bar k. Upon a centre pin attached to
the boss P is mounted the inclined plane », capable of turning in one
direction, but prevented from turning in the other by a stop pieces, and
this inclined plane is rendered adjustable in height by a set screw t.
The boss in which the 'screw n turns at one end has leather washers ⟫
which may be pressed by nuts, upon the screw so as to create
sufficient friction to prevent the screw from turning too freely. Upon
the end of the screw is fixed a ratchet wheel, within the teeth of
which is a driver 'mounted upon a lever y, one end of which turns
loosely upon the axis of the screw, the other end being situate over a
fixed part (see the detached view Fig. 6).
levers capable of turning upon fixed centres m. Upon the bar k is mounted
:. The operation is.as follows:-At the commencement of forming a cop
the screw is turned by the handle 1, so as to bring the inclined plane ŕ
to the end A, upon the running in of the carriage the part 2.thereof
will arrive in contact with the inclined plane and cause, the bark and
levers to turn upward upon the centres m, which motion will bring the
bottom of the slot in the arm'i in contact with the pin so as to effect
a turning of the lever d upon its centre, thereby bringing the usual gear
into operation for causing the rollers to give off the material. "This
having been accomplished the going out of the carriage will allow the
bar to fall downward, and the lever y, which by its weight has remained
on the stop, and thus cause the driver to travel over the teeth of
the ratchet wheel. w will now turn that wheel, and with it the screw n

page_text: so as to effect a travelling forward of the inclined plane ; at the next,
going in of the carriage the lever; d, will therefore, be raised sooner; and
so on for each stretch, and, thus the material given off by the rollers.
will be in proportion to the increasing size of the cop.",
Having thus described and ascertained the nature of our said Invention,
and the manner in which the same is to be performed, we desire it to be
understood that we claim, as secured to us under the above in part recited'
Letters Patent,―
Firstly. As applied to the differential motion of slubbing or roving
frames the use of the extended boss for carrying the wheels instead of
employing the shaft for that purpose.

Secondly. The method of balancing the lifting rail of slubbing or
roving frames.
Thirdly. In reference to machines of the mule class causing, the
material to be delivered by the rollers in a variable degree as the cop,
increases in size, and particularly for that purpose the employment of
the travelling inclined plane.

page_text: LETTERS PATENT to Leonard Kaberry, of Rochdale, in the County of
Lancaster, Manager, and Thomas Mitchell, of the same Place, Manager,
for the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS. FOR
PREPARING FOR SPINNING AND 'SPINNING COTTON, WOOL, AND OTHER FIBROUS
MATERIALS."
Sealed the 11th March 1859, and dated the 11th September 1858.
PROVISIONAL SPECIFICATION left by the said Leonard Kaberry and
Thomas Mitchell at the Office of the Commissioners of Patents, with...
their Petition, on the 11th September 1858.
We, LEONARD KABERRY, of Rochdale, in the County of Lancaster, Manager,"
and THOMAS MITCHELL, of the same Place, Manager, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR PREPARING FOR SPINNING AND SPINNING COTTON, WOOL, AND
MATERIALS," to be as follows:-
Our Invention relates, firstly, to the differential motion of slubbing or roving
frames, and consists in the application of a long boss, through which the
driving shaft passes, and upon which boss the wheels for the jack motion run
instead of upon the shaft.
Secondly, to a method of balancing the lifting rail. Upon the slide is cast
a rack in which is a pinion, and on the axle thereof a pulley, over which a...
chain passes, and from thence over another guide pulley at the upper part of..
the frame, a weight upon the said chain hanging downward.

page_text: Thirdly, our Invention consists in the use of bobbins formed of metal or of
metal tubes with wooden or other fianges.
Fourthly, our Invention relates to machines of the mule class, and consists
in causing the roving to be delivered by the rollers in a variable degree as the
carriage runs in, such variation taking place according to the increasing size of
the cop. A method of accomplishing this consists in causing the carriage
or part connected thereto to arrive in contact with a stop, by which the
rollers are caused to revolve, and this stop is traversed by a screw so as to
come into operation sooner or later.
!
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Leonard Kaberry and Thomas Mitchell in the Great Seal
Patent Office on the 11th March 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, LEONARD
KABERRY, of Rochdale, in the County of Lancaster, Manager, and THOMAS
MITCHELL, of the same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of September, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Leonard Kaberry and Thomas Mitchell, Her special license that
we, the said Leonard Kaberry and Thomas Mitchell, our executors, adminis-
trators, and assigns, or such others as we, the said Leonard Kaberry and
Thomas Mitchell, 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
MACHINERY OR APPARATUS FOR PREPARING FOR SPINNING AND SPINNING COTTON,
WOOL, AND OTHER FIBROUS MATERIALS," upon the condition, amongst others,
that we, the said Leonard Kaberry and Thomas Mitchell, or one of us, by
an instrument in writing under our hands and seals, or under the hand
and -seal of one of us, 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.

page_text: NOW KNOW YE, that I, the said Leonard Käberry, do hereby declare
the nature of our said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):
Our Invention relates, firstly, to the differential motion of slubbing or roving
frames, and is shewn at Fig. 1 of the accompanying Drawings. The main.
shaft of the said motion is at a, supported by the boss b, which, according to
the usual arrangement, terminates at the pinion e; according to our Invention,.
however, we extend it to the point d, and mount the wheels c, e, f, thereon.
instead of upon the shaft as usually practised. The arrangement as regards
the other parts of the apparatus is that in ordinary use.
Secondly, our Invention relates to bobbins of preparing machinery, which
we form of. metal. In Figs. 2 and 3 the barrel of the bobbin is shewn at a,
formed of thin sheet iron, which may be tinned; at the lower end it is attached
to a flange b of cast metal, in which are the recesses c for connexion with the
bobbin braid; the upper part of the barrel is narrowed at d, so as to form a
bush for running in contact with the spindle."
Thirdly, our Invention relates to a method of balancing the lifting rail of
slubbing or roving frames, which arrangement is shewn at Fig. 4. The.
lifting rail a is raised in the ordinary manner by the pinion b and rack c;.
but it is also provided with another rack d, in gear with which is a pinion e,
mounted upon a stud which also carries a pulley f. To this pulley a chain d
is attached, which, after passing over a guide pulley h, carries the counter-
balance weight i.
Fourthly, our Invention relates to such machines as the "mule," and
consists in causing the roving to be delivered by the rollers in a variable
degree as the carriage runs in, such variation taking place according to the
increasing size of the cop. Fig. 5 is a partial view of a mule with the
improvement adapted. The roller beam is shewn at a, the rollers of which
receive rotatory motion from the wheel 6 driven by the pinion e; this pinion
is carried by a lever d, which turns upon a centre at e, and it is provided on its
upper part with a clutch f, taking into a counterpart within the pulley g.
Upon the lever d therefore being turned upward or downward upon its centre,
the pinion c is brought into or out of connexion with the pulley accordingly
as the rollers are to revolve or remain stationary. This arrangement is that
in ordinary use, the said lever is usually so caused to turn upon its centre
by the arrival of the carriage in contact with an inclined plane attached
thereto, and the motion imparted to the rollers is therefore uniform in extent;
but according to our Invention we cause the inclined plane to move outward

page_text: as the cop increases, in, size, so that it is acted upon at successive, earlier
periods by the carriage, and a proportionate increased turning of the rollers is
effected. The following is an arrangement 'we adopt :-Upon the lever dis
a projecting pin h, situate within a slot formed in an arm i. This arm extends
from a bar k, which is mounted upon levers 1, capable of turning upon fixed-
centres m. Upon the bar is mounted a screw n, passing through a nut o,
which extends from a boss p, mounted so as to slide in guides formed upon
the bar k. Upon a centre pin q attached to the boss p is mounted the
inclined plane r, capable of turning in one direction, but prevented from
turning in the other by a stop piece s, and this inclined plane is rendered
adjustable in height by a set screw t. The boss in which the screw n turns at
one end has leather washers u, which may be pressed by nuts v upon the
screw, so as to create sufficient friction to prevent the screw n from turning
too freely. Upon the end of the screw n is fixed a ratchet wheel w, within
the teeth of which is a driver x, mounted upon a lever y, one end of which
turns loosely upon the axis of the screw n, the other end being situate over a
fixed part 2, (see the detached view, Fig. 6.) The operation is as follows:--
At the commencement of forming a cop, the screw is turned by the handle 1,
so as to bring the inclined planer to the end A; upon the running in of the
carriage the part 2 thereof will arrive in contact with the inclined plane r, and
cause the bark and levers to turn upward upon the centres m, which motion
will bring the bottom of the slot in the arm i in contact with the pin h, so as
to effect a turning of the lever d upon its centre, thereby bringing the usual
gear into operation for causing the rollers to give off the material. This
having been accomplished, the going out of the carriage will allow the bar k
to fall downward, and the lever y, which by its weight has remained on the
stop, and thus cause the driver to travel over the teeth of the ratchet
wheel w, will now turn that wheel, and with it the screw n, so as to effect a
travelling forward of the inclined plane r; at the next going in of the carriage
the lever d will therefore be raised sooner, and so on for each stretch, and thus
the material given off by the rollers will be in proportion to the increasing
size of the cop.
Having thus described and ascertained the nature of our said Invention,
and the manner in which the same is to be performed, we desire it to be
understood that we claim as secured to us under the above in part recited
Letters Patent,—
Firstly, as applied to the differential motion of slubbing or roving frames,
the use of the extended boss for carring the wheels instead of employing the
shaft for that purpose.

page_text: Secondly, forming the bobbins, for preparing machinery, of metal.
Thirdly, the method of balancing the lifting rail of slubbing or roving
frames.
Fourthly, in reference to machines of the mule class, causing the material
to be delivered by the rollers in a variable degree as the cop increases in size,
and particularly for that purpose the employment of the travelling inclined
plane.
In witness whereof, I, the said Leonard Kaberry, have hereunto set
my hand and seal, this Tenth day of March, in the year of our Lord
One thousand eight hundred and fifty-nine.
LEONARD KABERRY. (L.S.)
