Spinner, for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY FOR
PREPARING TO BE SPUN WOOL AND OTHER FIBROUS SUBSTANCES WHEN MIXED
WITH WOOL."
L
Sealed the 15th March 1854, and dated the 24th January 1854.
PROVISIONAL SPECIFICATION left by the said John Bapty at the Office
of the Commissioners of Patents, with his Petition, on the 24th January
1854.
I, JOHN BAPTY, of Leeds in the County of York, Yarn Spinner, do hereby
declare the nature of the said Invention for "CERTAIN IMPROVEMENTS IN MA-
CHINERY FOR PREPARING TO BE SPUN WOOL AND OTHER FIBROUS SUBSTANCES WHEN
MIXED WITH WOOL" to be as follows:-
This Invention consists in a novel arrangement of rollers placed in front of
the doffing cylinders of ordinary wool carding engines. These rollers have a
rotary and horizontal motion whereby the wool doffed from such doffing
cylinders in passing between these rollers is condensed into continuous rovings.

by the said John Bapty in the Great Seal Patent Office on the 24th
July 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BAPTY, of Leeds, in the County of York, Yarn Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of January, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Bapty, Her special license that I, the said John Bapty, my executors,
administrators, and assigns, or such others as I, the said John Bapty, 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 Íslands, and
Isle of Man, an Invention for "CERTAIN IMPROVEMENTS IN MACHINERY FOR
PREPARING TO BE SPUN WOOL AND OTHER FIBROUS 'SUBSTANCES WHEN MIXED WITH
WOOL," upon the condition (amongst others) that I, the said John Bapty, 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, and cause the same to be filed in the Great Scal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
of
NOW KNOW YE, that I, the said John Bapty, do hereby declare the nature
I my said Invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement,
reference being had to the Drawing hereunto annexed, and to the letters and
figures marked thereon (that is to say):-
This Invention consists in the application to carding engines of an arrange-
ment of rollers for the purpose of condensing into continuous rovings the
wool or wool and other fibrous substance as it is doffed from the doffing
cylinder.
In the accompanying Drawing, Fig. 1 is a plan view of a carding engine
thus provided; Fig. 2 is a side elevation of the same; and Fig. 3 is a detached
view shewing the guide for holding the spool. A, A, A, is the framework of an
ordinary wool carding engine. B, B, shews part of the main cylinder of the

page_text: machine. C, C, is the doffer cylinder clothed with rings or fillets of card
cloth, of about three inches in width, and set at a small distance apart as shewn
at Fig. 1. D, D, is the pulley and strap for driving the doffing roller in the
usual manner. E, E, is the doffing knife or comb for stripping off the wool
from the doffing cylinder actuated by the usual crank motion. F, F, is a
cylinder, covered with leather, and rotating at nearly the same surface speed
as the doffing cylinder. G, G, is a pair of small rollers also covered with
leather. They are mounted in a frame composed of end pieces which are held
together by means of, sliding rods The ends of these rods work in the
guides 1, 1. These rollers are placed on the upper side of the cylinder F, and
receive rotary motion therefrom by friction of contact. H, H, is a sheet iron
cylinder, driven at a slightly superior speed to that of the cylinder F. On
this cylinder is placed the spool or 'bobbin I, I, upon which the rovings are
wound. In the lower part of the framework A, A, is mounted the crank
shaft K, which is driven in the usual manner. A bevil wheel on this shaft
takes into another bevil wheel on the diagonal shaft L, which at its upper end
carries a plate for receiving a crank pin m, which is made fast thereto. One
end of a connecting rod n, works upon this pin, and the other is attached by
means of a joint to the adjacent end piece O, of the roller frame for the
purpose of communicating a reciprocating motion (in the direction of their
axes) to the rollers G, G. M is a bar extending across the machine, and
provided with pins for the purpose of guiding the rovings towards the bobbin
or spool I. p and q are jointed guides usually employed for keeping the
bobbin in its place; r, s, and t, are the worm, worm wheel, and heart wheel,
such as are commonly used for traversing winding on motions. P, is a spur
wheel upon the end of the doffer cylinder in gear with a pinion Q, which also
actuates the train of spur wheels R, R, R, and gives the requisite motion to
the cylinders F and H.
From the foregoing explanation it will be understood that the sliver as it is
doffed from the doffing cylinder C, is taken up and passed between the cylinder
F, and the small rollers G, G, where, by the combined action of the rotating
friction surfaces, it is rolled or condensed into a roving, and passing thence
over the bar M, is wound upon the spool I, I.
Having now set forth the nature of my Invention of " Improvements in
Machinery for Preparing to be Spun Wool and other Fibrous Substances when
mixed with Wool," I wish it to be understood that under the above in part
recited Letters Patent, I claim the application to wool carding engines of a
cylinder and rollers constructed and operated as above described for the

page_text: purpose of rolling and condensing the slivers as they pass from
cylinder to the bobbin or spool. . .
