PROVISIONAL SPECIFICATION left by the said Benjamin Dobson and
Daniel Greenhalghat the Office of the Commissioners of Patents, with
their Petition on the 9th June 1863.
We, BENJAMIN DOBSON, of Bolton, in the County of Lancaster, Machine
Maker, and Daniel Greenhalgh, of the same Place, Manager, do hereby
declare the nature of the said Invention for "CERTAIN IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES,"
to be as follows:-
Our Invention is applicable to carding engines, drawing frames, slubbing
frames, and roving frames, and other machines used in preparing cotton
and other fibrous substances, in which the fleece, sliver, slubbing, or roving
is conveyed through funnels or guides, and it consists in subjecting the
fleece or slivers of carding engines to the action of steam as they pass from
the doffer to the calender rollers or coiler and the slivers of drawing frames
from the delivering roller to the can, and the slubbings or rovings in
slubbing frames and roving frames as they pass from the delivering roller
to the spool or bobbin.
The object and effect of our Invention is to lay the fibres and prepare them
for being spun.
In performing our Invention, the funnel or guide is perforated and passes

page_text: through a box to which steam is admitted through a syphon pipe or other
equivalent apparatus to exclude the water of condensation, the funnel or
guide through which the fleece, sliver, slubbing, or roving passes, or an
additional funnel or guide is connected to a tap in the steam pipe by a
lever and link or other equivalent agents to shut off the steam when the
fleece, sliver, slubbing, or roving breaks or ceases to pass forward.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Benjamin Dobson and Daniel Greenhalgh in the Great Seal
Patent Office on the 8th December 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, BENJAMIN
DOBSON, of Bolton, in the County of Lancaster, Machine Maker, and DANIEL
GREENHALGH, of the same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of June, in the year of our Lord One
thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the said
Benjamin Dobson and Daniel Greenhalgh, Her special license that we, the said
Benjamin Dobson and Daniel Greenhalgh, our executors, administrators, and
assigns, or such others as we, the said Benjamin Dobson and Daniel Green-
halgh, our executors, administrators, and assigns, should at any timeagree 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 "CERTAIN IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES," upon the
condition (amongst others) that we, the said Benjamin Dobson and Daniel
Greenhalgh, our executors or adininistrators, by an instrument in writing
under our, or their, or one of our or their hands and seals, should par.
ticularly 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 Benjamin Dobson and Daniel Green-
halgh, 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) :-

page_text: Our Invention is applicable to carding engines, drawing frames, slubbing
frames, and roving frames, and other machines used in preparing cotton
and other fibrous substances, in which the fleece, sliver, slubbing or roving
is or may be conveyed through funnels or guides, and it consists in sub-
jecting the fleece or slivers of carding engines to the action of steam as they
pass from the doffer to the calender rollers or coiler and the slivers of drawing
frames from the delivering rollers to the can, and the slubbings or rovings in
slubbing frames and roving frames as they pass from the delivering roller to
the spool or bobbin.
The object and effect of our Invention is to lay the fibres and prepare them
for being spun.
In performing our Invention, the funnel or guide is perforated and
passes through a box to which steam is admitted through a syphon pipe
or other equivalent apparatus to exclude the water of condensation, the
funnel or guide through which the fleece, sliver, slubbing or roving
passes; or au additional funnel or guide is connected to a tap in the
steam pipe by a lever and link, or other equivalent agents, to shut off the
steam when the fleece, sliver, slubbing or roving breaks or ceases to pass
forward.
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 represents part of a carding engine and coiler to which our improve-
ments are applied; Fig. 2 is a front view of the same.
a is the doffer; b, the doffing comb; c, the funnel or trumpet mouth;
d, d, the calender rollers; and e, the coiler; these parts are made as usual.
Under the calender rollers, or in any other convenient position, is placed
the box f shewn in section on an enlarged scale in Fig. 3. Steam is
admitted into this box by the pipe g which is provided with a tap h, see Fig. 2.
The end of the pipe g forms a syphon to prevent the condensed steam
which is carried off by the pipe i from rising in the box f; to the upper
part of the box f is connected the pipe i, which conveys the steam into
the chamber k, through which the funnel c passes, the funnel being perfo-
rated to admit the steam to the sliver as it passes through, as shewn in
Fig. 3. The sliver is thus subjected to the action of steam as it proceeds
from the doffer a to the calender rollers d, from which it is taken to the
coiler and deposited into the can / as usual. When the sliver breaks or
ceases to pass forward the tap h is closed to shut off the steam by means

page_text: of the levers m and n, the link o, and lever p, which is fixed to the plug of
the tap. The lever m bears against and is held in position by the sliver as it
passes from the end of the funnel c to the calender rollers d, d; consequently
as soon as the sliver breaks, the lever n, which is slightly weighted, drops into
the position indicated by a dotted line and moves the lever p sufficiently to
close the tap h.
It is evident that the same object can be accomplished when the trumpet
mouth is held up by the sliver, by connecting the tap to a lever which is
influenced by the falling down of the trumpet mouth:
Fig. 4 represents a modification of our Invention; in this arrangement the
funnel c passes through the box f.
Figs. 5 and 6 represent another modification of our Invention; in this case
the fleece of fibres on leaving the doffer is taken over a box q, in which is a
perforated tube 1, through which the steam which is supplied by the pipe g
passes
The foregoing description and the Drawings have only reference to the
mode of applying our Invention to carding engines, but it will be apparent to
any competent workman how it is to be applied to drawing frames, slubbing
frames, and roving frames, or to any other machines used in preparing cotton
and other fibrous substances, in which the fleece, sliver, slubbing or roving is
conveyed through funnels or guides.
The object and effect of our Invention is to improve the quality and strength
of the yarn.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim the subjecting the fleece,
sliver, slubbing or roving of cotton or other fibrous substances, to the action
of steam, in the manner and for the purpose described.
In witness whereof, I, the said Benjamin Dobson, have hereto set my
hand and seal, this Fourth day of December, in the year of our Lord
One thousand eight hundred and sixty-three.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, BENJAMIN
DOBSON, of Bolton, in the County of Lancaster, Machine Maker, and DANIEL
GREENHALGH, of the same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters

upon the
condition (amongst others) that we, the said Benjamin Dobson and Daniel

under our, or their, or one of our or their hands and seals, should' par-
ticularly 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 Benjamin Dobson and Daniel Green-
halgh, 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):-

page_text: Our Invention is applicable to carding engines, drawing frames, slubbing
frames, and roving frames, and other machines used in preparing cotton
and other fibrous substances, in which the fleece, sliver, slubbing or roving
is or may be conveyed through funnels or guides, and it consists in sub-

frames from the delivering rollers to the can, and the slubbings or rovings in
slubbing frames and roving frames as they pass from the delivering roller to
the spool or bobbin.
The object and effect of our Invention is to lay the fibres and prepare them
for being spun.
In performing our Invention, the funnel or guide is perforated and
passes through a box to which steam is admitted through a syphon pipe
or other equivalent apparatus to exclude the water of condensation, the
funnel or guide through which the fleece; sliver, slubbing or roving
passes; or an additional funnel or guide is connected to a tap in the
steam pipe. by a lever and link, or other equivalent agents, to shut off the
steam when the fleece, sliver, slubbing or roving breaks or ceases to pass
forward.
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 represents part of a carding engine and coiler to which our improve-
ments are applied; Fig. 2 is a front view of the same.
a is the doffer; b, the doffing comb; c, the funnel or trumpet mouth;
d, d, the calender rollers; and e, the coiler; these parts are made as usual.
Under the calender rollers, or in any other convenient position, is placed
the box f shewn in section on an enlarged scale in Fig. 3. Steam is
admitted into this box by the pipe g which is provided with a tap h, see Fig. 2.
The end of the pipe 9 forms a syphon to prevent the condensed steam
which is carried off by the pipe i from rising in the box f; to the upper
part of the box fis connected the pipe i, which conveys the steam into
the chamber k, through which the funnel c passes, the funnel being perfo-
rated to admit the steam to the sliver as it passes through, as shewn in
Fig. 3. The sliver is thus subjected to the action of steam as it proceeds.
from the doffer a to the calender rollers d, from which it is taken to the
coiler and deposited into the can 7 as usual. When the sliver breaks or
ceases to pass forward the tap h is closed to shut off the steam by means

page_text: of the levers m and n, the link o, and lever p; which is fixed to the plug of
the tap. The lever m bears against and is held in position by the sliver as it
passes from the end of the funnel c to the calender rollers d, d; consequently
as soon as the sliver breaks, the lever n, which is slightly weighted, drops into
the position indicated by a dotted line and moves the lever p sufficiently to
close the tap h.
It is evident that the same object can be accomplished when the trumpet
mouth is held up by the sliver, by connecting the tap to a lever which is
influenced by the falling down of the trumpet mouth.
Fig. 4 represents a modification of our Invention; in this arrangement the
funnel c passes through the box f.
Figs. 5 and 6 represent another modification of our Invention; in this case
the fleece of fibres on leaving the doffer is taken over a box q, in which is a
perforated tube r, through which the steam which is supplied by the pipe g
passes.
The foregoing description and the Drawings have only reference to the
mode of applying our Invention to carding engines, but it will be apparent to
any competent workman how it is to be applied to drawing frames, slubbing
frames, and roving frames, or to any other machines used in preparing cotton
and other fibrous substances, in which the fleece, sliver, slubbing or roving is
conveyed through funnels or guides.
The object and effect of our Invention is to improve the quality and strength
of the yarn.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim the subjecting the fleece,
sliver, slubbing or roving of cotton or other fibrous substances, to the action
of steam, in the manner and for the purpose described.
In witness whereof, I, the said Benjamin Dobson, have hereto set my.
hand and seal, this Fourth day of December, in the year of our Lord
One thousand eight hundred and sixty-three.
