PROVISIONAL SPECIFICATION left by the said Edward Lawson
at the Office of the Commissioners of Patents, with his Petition,
on the 1st November 1852.
I, EDWARD LAWSON, Machine Maker, of Leeds, in the County of
York, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN MACHINERY FOR PREPARING TO BE SPUN HEMP, FLAX, TOW,
WOOL, SILK, COTTON, AND OTHER FIBROUS MATERIALS," to be as follows:→
In a new arrangement and combination of the combing. machine
described in Specification of Patent granted to Josue Heilmann, of
Mullhausen, France, for "Improvements in certain Machines used for
preparing to be spun Cotton, Wool, and other Fibrous Materials," and
dated at Westminster, the 25th day of February, A.D. 1846, with the
screw or circular gill drawing head; and, this I propose to effect by

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date-the First day of November, in the
of our Lord One thousand eight hundred and fifty-two, in the six-
teenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Edward Lawson, Her especial
license that I the said Edward Lawson, "my executors, administra-
tors, and assigns,.. or such others as I, the said, Edward Lawson, my
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 the Isle of Man, an Invention for
"CERTAIN IMPROVEMENTS IN MACHINERY FOR PREPARING TO. BE SPUN HEMP,
FLAX,
Tow, WOOL, SILK, COTTON, AND OTHER FIBROUS MATERIALS, upon
condition (amongst others) that I, the said Edward Lawson, by an
instrument in writing under my hand and seal, should particularly
"describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed:*:****
NOW KNOW-YE, that I, the said Edward Lawson; do hereby
declare the nature of the 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 my Invention consists in combining with the machine
.well known as Heilmann's combing machine, or machines acting in the
same manner, a "screw gill" or "circular gill" drawing head; that is,
in place of taking the combed sliver as it comes from the machine, and

page_text: putting it into a can or other receptacle or winding it on a bobbin, I
take the sliver from each head (where there are more heads than one),
and bring them together, and then pass them through a "screw gill'
or "circular gill" drawing apparatus. I find by so doing that the sliver
is rendered not only more even, but will hold together much better than
the sliver which comes from the machine without passing through a
drawing process. I do not consider it necessary to give any Drawings to
shew the mode of combining the "screw gill" or "circular gill" drawing
apparatus with the said combing machines, as it is entirely a matter of
driving and speeding from some part of the combing machine which
would vary in applying it to different machines, and which any mechanic
having the idea and explanation herein given will be able to carry into
effect; but I may here state, that I should prefer to place the screw or
circular gill drawing head about the position that the last delivery rollers
occupy, and it might be driven by the same shaft or by suitable geering
from the main shaft, of course so speeded that the drawing apparatus
would take up the sliver as fast as it was delivered by the drawing or
detaching rollers of the machine.
Having now fully described the nature of my Invention, and in what
manner it may be carried into effect, it will be understood that I do not
claim as of my Invention either the combing machine or circular gill
or screw gill drawing apparatus, which are well known, but only their
combination in the manner herein-before described.
In witness whereof, I, the said Edward Lawson, have hereunto
set my hand and seal, this
day of April, One thousand
EDWARD LAWSON. (L.s.)
Signed, sealed, and delivered (being first
duly stamped) by the within-named
Edward Lawson in the presence of
H. LONGMAN.
