Year: 1861

page_text: LETTERS PATENT to John Hodgkinson, of Bolton, in the County of Lan-
caster, Cotton Spinner, and Daniel Greenhalgh, of the same Place,
Manager, for the Invention of "IMPROVEMENTS IN MACHINERY OR APPA-
BATUS FOR PREPARING COTTON, COTTON WASTE, OR OTHER FIBROUS MATERIALS
TO BE SPUN."
Sealed the 2nd May 1862, and dated the 13th November 1861.
PROVISIONAL SPECIFICATION left by the said John Hodgkinson and
Daniel Greenhalgh at the Office of the Commissioners of Patents, with
their Petition, on the 13th November 1861.
We, JOHN HODGKINSON, of Bolton, in the County of Lancaster, Cotton
Spinner, and DANIEL GREENHALGH, of the same Place, Manager, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR PREPARING COTTON, COTTON WASTE, OR OTHER FIBROUS MATERIALS
TO BE SPUN," to be as follows:-
This Invention relates to improvements applicable to certain descriptions of
combing machines, and consists in collecting the fibrous material from the
doffers of the machine upon a creeper of any material, or upon rollers or
other mechanical contrivance for collecting the doffed material. In connec-
tion with the creeper or collector there is a funnel, through which the material
passes, and after passing between rollers comes out in a sliver and enters the
coiler.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Hodgkinson and Daniel Greenhalgh in the Great Seal
Patent Office on the 13th May 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
HODGKINSON, of Bolton, in the County of Lancaster, Cotton Spinner, and
DANIEL GREENHALGH, of the same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said John Hodgkinson and Daniel Greenhalgh, Her special licence that we, the
said John Hodgkinson and Daniel Greenhalgh, our executors, administrators,
and assigns, or such others as wc, the said John Hodgkinson and Daniel
Greenhalgh, 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 COTTON, COTTON WASTE, OR OTHER
FIBROUS MATERIALS TO BE SPUN," upon the condition (amongst others) that we,
the said John Hodgkinson and Daniel Greenhalgh, our executors or adminis-
trators, by an instrument in writing under our, or their, or one of 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 John Hodgkinson 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 ascer-
tained in and by the following statement (that is to say):
This Invention relates to improvements applicable to certain descriptions of
combing machines, and consists in collecting the fibrous material from the
doffers of the machine upon a creeper of any material, or upon rollers. In
connection with the creeper or collector there is a funnel or trumpet, through
which the material passes, and after passing betwixt rollers comes out in a
sliver, which can be entered into a coiler, wound on a bobbin, or passed into
a head of drawing. We also employ a horizontal shaft with clearers, which

page_text: revolve underneath each brush and doffer, for the purpose of gathering up the
short fibre and dust, and consequently improving the other material.
These improvements will be clearly understood by the following description
thereof, reference being had to the figures and letters on the accompanying
two Sheets of Drawings, in which Fig. 1 is a side elevation of part of Heil-
mann's combing machine, having one arrangement of our improvements
attached; Fig. 2 is an end elevation, and Fig. 3 a plan of the same; Fig. 4
is a side elevation of part of a combing machine, having another arrangement
of our improvements; and Fig. 5 a plan of the same.
In Figs. 1, 2, and 3, the creeper or flexible apron for gathering up the
waste as it falls from the doffers of the combing machine is shewn at a; it
leads and delivers the waste to the funnel or trumpet b, to the calender
rollers c, from whence it comes out as a sliver, which may be entered into the
coiler d, or passed into a head of drawing. The clearers are shewn at e;
they are composed of bobbins covered with flannel, and fixed to the horizontal
shaft f. The said clearers are employed for gathering up the short fibre and
dust, and thereby improve the material which passes through the machine.
In Figs. 4 and 5 we represent a lap or bobbin, instead of the coiler, for
receiving the material from the calender rollers, funnel or trumpet, and creeper.
The material is collected from the doffers of the combing machine on to the
creeper g, and is led onwards to the funnel or trumpet h, and over the calender
roller i, to the lap roller or bobbin k, upon which it is wound into a lap or
bobbin. The sliver is so level that it can be thus easily formed into a lap or
bobbin, and recombed, and if desired still further to improve it, it can be carded
and afterwards recombed, which operations make the waste equal to the cotton
in cleanness, and will spin within fifty hanks of the counts of the original
cotton with less per cent. of waste, there being no scutchings and no drop-
pings. Again; by being conveyed regularly from the doffer, the comb cannot
be damaged by the waste or material accumulating until it filled the half lap
or comb, and thereby break the pins.
Having now described the nature and particulars of our said Invention, and
the manner in which the same is to be performed, we desire it to be under-
stood that we claim to Heilmann's or other combing machine,―
First, the application of a creeper or flexible apron in connection with a
funnel or trumpet and calender rollers, for the purpose of gathering the waste
as it falls from the doffer and converting it into a sliver, to be led to a coiler,
head of drawing, or to a lap or bobbin.
And, secondly, the application of clearers fixed to or on a horizontal shaft for

page_text: gathering up the short fibre, and dust from the waste or material as it passes
from the brushes to the doffers, as such improvements are herein described and
illustrated in the accompanying two Sheets of Drawings.
In witness whereof, we, the said John Hodgkinson and Daniel Greenhalgh,
have hereunto set our hands and seals, this Sixth day of May, in the
year of our Lord One thousand eight hundred and sixty-two.
(L.S.)
JOHN HODGKINSON.
DANIEL GREENHALGH. (L.S.)

within-named John Hodgkinson
