PROVISIONAL SPECIFICATION left by the said Edward Barlow, James
Clough, and Francis Hamilton at the Office of the Commissioners of
Patents, with their Petition, on the 14th October 1862.
We, EDWARD BARLOW, of Bolton-le-Moors, in the County of Lancaster,..
Machine Maker, and JAMES CLOUGH and FRANCIS HAMILTON, of the same
Place, Foremen, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN MACHINERY FOR DRIVING COTTON GINS, AND FOR PREPARING
AND COMBING COTTON AND OTHER FIBROUS SUBSTANCES," to be as follows:-
Our improvements in machinery for driving cotton gins consist in supporting
the axle of the driving and fly wheel shaft on antifriction rollers, and in
placing antifriction rollers on each side of the said axles, by this means the
friction, and consequently the power required for driving, are reduced. Similar
antifriction rollers are or may be applied to the axle of the roller of the cotton.
gin...
Our improvements in machinery for preparing cotton and other fibrous

page_text: substances are applicable to slubbing frames, roving frames, and other
machines of the like description, and consist in the application to such
machines of an apparatus by means whereof the irregularities in the taking
up of the bobbins are prevented.
In performing our Invention the motion from the driving shaft or the
differential motion is transmitted to the bobbins by two or more wheels
connected to the differential motion gearing into two or more wheels in the
swing frame; these wheels are either of different pitches or of the same pitch,
but so connected to their respective axles that the tooth of one wheel coincides
with the space between the teeth of the others; two or more wheels may also
be applied on the bobbin shafts. By this means what is technically called
"back lash" in the gearing and the fluctuations of the roving between the
delivery rollers and the spindles are avoided.
Our improvements in machinery for combing cotton and other fibrous
substances is applicable to the circular combing machines, and it consists in
making the weight by which the sliver is held in the guide spout with two
projections fitting in slots in the sides of the spout; these slots have each a
shoulder or set-off, so that when the weight is in its place it cannot be
displaced by the extra depth of the sliver or by the moving of the spout.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Barlow, James Clough, and Francis Hamilton in the
Great Seal Patent Office on the 13th April 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
BARLOW, of Bolton-le-Moors, in the County of Lancaster, Machine Maker,
and JAMES CLOUGH and FRANCIS HAMILTON, of the same Place; Foremen,
send greeting.

page_text: 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 "CERTAIN IMPROVEMENTS IN MACHINERY FOR DRIVING COTTON GINS,
AND FOR PREPARING AND COMBING COTTON AND OTHER FIBROUS SUBSTANCES," upon
the condition (amongst others) that we, the said Edward Barlow, James
Clough, and Francis Hamilton, our executors or administrators, by an instru-
ment 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 calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Edward Barlow, James Clough, and
Francis Hamilton 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 :-
The nature of our improvements in machinery for driving cotton gins
consists in supporting the axles of the driving and fly wheel shaft on anti-
friction rollers, and in placing antifriction rollers on each side of the said
axles, by this means the friction, and consequently the power required for
driving, are reduced. Similar antifriction rollers are or may be applied to
the axles of the roller of cotton gins.
Our improvements in machinery for preparing cotton and other fibrous
substances are applicable to slubbing frames, roving frames, and other
machines of the like description, and consist in the application to such
machines of additional wheels to the wheels now employed for transmitting:
the motion from the differential wheels to the spindles, by means' whereof
the irregularities in the taking up of the bobbins are prevented.
Our improvement in machinery for combing cotton and other fibrous
substances is applicable to the circular combing machines, and it consists in
making the weight by which the sliver is held in the guide spout with two
projections fitting in slots in the sides of the spout; these slots have each a
shoulder or set-off, so that when the weight is in its place it cannot be
displaced by the extra depth of the sliver or by the moving of the spout.
And in order that our. Invention may be fully understood and readily carried
into operation, we will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Fig. 1 is an elevation, and Fig. 2 a plan, of a driving apparatus suitable for:
working cotton gins by manual labour. a is the driving shaft, the axles of
which are supported by the antifriction rollers b; the trunnions of these

page_text: rollers revolve in the standards c. The antifriction rollers d, d, are placed
at each side of the axles to prevent them moving laterally. On the shaft a is
fixed the fly wheel e, the circumference of which forms the driving pulley for
the strap by which the roller of the cotton gin is driven. In Fig. 3, f represents
the roller of an ordinary cotton gin; the axles a of this roller are supported and
stayed laterally by the antifriction rollers b and d, as shewn in Figs. 1 and 2;
or any other convenient arrangement of antifriction rollers may be applied to the
axles of the apparatus for driving cotton gins, and to the axles of the rollers
of cotton gins, for the purpose of reducing friction. Fig. 4 is an elevation,
and Fig. 5 a plan, of part of a slubbing or roving frame to which our improve-
ments are applied. In these views g is the driving shaft; g', a mitre wheel.
forming part of the differential motion common to machines of this description;
g is a spur wheel fixed to the mitre wheel g'; h is a radial arm suspended to
the shaft g, and connected to the swing frame i, in which is the carrier
wheelj, driven by the wheel 9%, and driving the wheel k on the shaft 7; this
wheel gears into the wheel mi on the shaft n. The shafts and n revolve in
bearings attached to the lifting rail. The parts above enumerated and all the
remaining parts of the machine are made in the usual manner.
Our improvements consist in the application of the additional wheels g³ and j';.
the former is fixed to the wheel g³, and the latter to the carrier wheel j. The
wheels and are made by preference of a finer pitch than the wheels g
and j, or they may be of a coarser pitch, or else they may be of the same
pitch but so connected to their respective axles that the tooth of one wheel
coincides with the space between the teeth of the other wheel on the same
axle; additional wheels may also be attached to the wheels k and m, but in
practice the additional wheels g³ and give satisfactory results, and prevent
what is technically called "back lash" in the gearing, the fluctuations or
irregularities of the rovings between the delivery rollers and the spindles
occasioned by the "back lash" are consequently avoided. This part of our
Invention may be modified by making the additional wheels with diagonal
teeth, or teeth set at an angle to the axis, or the wheels g³, j, k, and m may
be made with diagonal teeth. Fig. 6 is an elevation, and Fig. 7 a plan, of
a guide spout and weight forming part of one of Lister's Patent circular
combing machines constructed according to our improvements; o is the guide
spout, and p the weight which is made with two projections p', fitting in the
slots of of the guide spout; these slots have each a shoulder or set-off, so that
when the weight is in the guide spout it cannot be displaced by the extra
depth of the sliver passing under it nor by the shaking or moving of the
guide
spout.

page_text: Having thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim,-
First, the application of antifriction rollers to the axles of the rollers of
roller cotton gins, and to the driving shafts of apparatus for driving cotton
gins, as described.
Secondly, the application of additional wheels to the gearing now employed
in communicating motion from the differential wheels to the spindles of
slubbing frames, roving frames, and other machines of the like description, as
described.
And lastly, the application of projections on the weights fitting in slots in
the guide spouts of the machines known as Lister's Patent combing machines
as described.
In witness whereof, we, the said Edward Barlow, James Clough, and
Francis Hamilton, have hereto set our hands and seals, this Ninth
day of April, in the year of our Lord One thousand eight hundred
and sixty-three.
