PROVISIONAL SPECIFICATION left by the said William Brown at the
Office of the Commissioners of Patents, with his Petition. on the
23rd January 1861.
I, WILLIAM BROWN. of Wigan. in the County of Lancaster. Spinner and
Manufacturer, do hereby declare the nature of the said Invention for "AN
IMPROVED STRIPPER FOR CARDING ENGINES," to be as follows:
Instead of stripping by hand as heretofore. I employ at the back of the
ordinary card cylinder a roller covered with wire. card, or other suitable con-
trivance, which toller is advanced backwards and forwards every hour or other
required time, by means of a worth and toothed wheel, or other suitable con-
trine. Belind the eller there is a comb, having an up-and-down motion
imparted to it by a crank on e centric. When the roller is advanced to the
main card cylinder it is caused to dwell the required time, and strips the

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BROWN, of Wigan, in the County of Lancaster, Spinner and Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria by Her Letters
Patent, bearing date the Twenty-third day of January, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Brown, Her special licence that I, the said William Brown, my
executors, administrators, and assigns, or such others as I, the said William
Brown, 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 Isle of Man, an Invention for "AN IMPROVED STRIPPER
FOR CARDING ENGINES," upon the condition (amongst others) that I, the said
William Brown, my executors or administrators, by an instrument in writing
under my, 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 I. the said William Brown, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):
In order to strip the main card cylinder from dust, dirt, and extraneous
matter, I employ at the back of the cylinder a stripping roller covered with
wire card, which roller is similar to what has been before used, but instead of
allowing it to be always in contact with the main card cylinder, I cause it to
move forwards and backwards every hour or other desired interval of time, by

page_text: means of crank pins put in motion by toothed wheels in connection with a worm
and toothed wheel or other suitable contrivance. Behind the stripping roller
I employ a comb, having an up-and-down motion imparted to it by a crank
or eccentric. When the roller is advanced to the main cylinder it dwells the
required time as the crank pins pass the centres and strips the cylinder; and
when it has returned to its backward position the comb strips the roller, and
the strip falls below amongst the fly.
This Invention will be clearly understood by referring to the figures and
letters on the accompanying Sheet of Drawings. in which Fig. 1 is a back
view, and Figs. 2 and 3 side elevations, of part of a carding engine having my
improvements attached.
a represents part of the framework of the machine: b. the main card
cylinder: c. the licker-in roller: d. the lap roller: e. the stripping roller; and
f. the shaft to which it is fixed. The said shaft f is not arranged to work in
stationary bearings. and thus maintain the roller always in contact with the
main cylinder, but turns in bearings in arms or levers g. fixed to the shaft h,
vibrating to and fro in the bearings i, so that the roller may be advanced to
the main cylinder. as shewn by the full lines, Fig. 1, and removed from it. as
shewn by the dotted lines, as often as required. At one end of the shaft
there is a fast pulley ; and a loose pulley k. and at the other end there is a fast
pulley and a loose pulley m. The pulleys j, k, are connected by the strap n
to the pulley o, fixed to the shaft of one of the upper rollers, so that when the
strap n is on the fast pulley j. the stripping roller shall move at a quicker
speed than the main card cylinder, but in the same direction at their sides of
contact. The pulleys and m are connected by the crossed strap p to the
small pulley g, also fixed to the shaft of one of the upper rollers, so that when
the stripping roller has been brought back, and the strap p is on the fast
pulley 7, the stripping roller shall revolve in a contrary direction.
The comb for stripping or doffing the stripping roller e is shewn at r; it is
fastened to the bar s, held by the arms or levers t, fixed to the shaft u. at one end
of which shaft is a short lever v. connected by the rod c to the eccentric zon
the licker-in shaft. so that as the eccentric revolves an up-and-down motion is
given to the comb. The stripping roller is moved forwards and backwards
every hour or other desired interval of time by connecting the arms or levers g
by rods y_to_crank pins z, one fixed to the toothed wheel a', and the other to
the disc b. fixed to the shaft c', which works loosely in its bearings, so that one
end may rise and fall sufficiently to enable the toothed wheel a to be in or
out of gear with the pinion or toothed wheel d fixed at the end of the shaft of

page_text: the lap roller d. When the two wheels are in gear the crank pins revolve
and move the stripping roller to and fro, but as this is only required at intervals
there is a meter or measuring apparatus to regulate the movement. To the
shaft c' there is fixed a disc e', having in its circumference a notch, which on
its arrival at the pin f', allows the disc and shaft to descend so as to place the
two toothed wheels out of gear. At one end of the lap roller d there is a
worm or thread g' gearing into the worm wheel h', having fixed to it n heart
or cam k¹, which, as it revolves, raises by means of the pin the shaft c', lifts
the notch of the disc off the pin f; and places the toothed wheels a' and d¹ in
gear with each other, and when a slight turn has been made, the plain part of
the disc e¹ is supported on the pin f, and the wheels remain in gear until the
notch comes over the pin, and allows the disc and shaft to descend. These
toothed wheels may be of any pitch and numbers of teeth, according to the
interval of time between the operations. The straps are shifted alternately by
fixing their forks to bent levers on each side of the framing, which levers
are connected to slotted rode, in the slots of which work pins fixed to
the vibrating arms g, so that when the arms are advancing to their foremost
position the strap n is shifted to the fast pulley i, and the strap p to the loose
pulley m, thus causing the stripping roller to strip the main card cylinder, and
when the levers are returned to their backward position the strap p is shifted
to the fast pulley 1. and the strap n to the loose pulley k, and the stripping
roller is turned in a reverse direction at a slower speed, so that it may be
stripped or deffed by the comb. The wire card of the stripping roller is made
to enter the wire card of the main cylinder. and when they revolve thus in
contact the main cylinder is stripped from fly, dust, and wiry substances so
effectually as to require no supervision or hand stripping at all, the work being
performed greatly superior to the generality of hand stripping. Instead of
giving a vibrating movement to the shaft and the stripping roller e. they may
be made to traverse to and fro in a straight line by placing the shaft in a slot
or slide, and the mechanical contrivances for giving the straight or vibrating
movement of the roller. and also for measuring or regulating the times of its
action, may be varied as desired. and the up-and-down movement of the comb
for stripping or clearing the stripping roller may he imparted by a crank fixed
to any suitable shaft.
Having now described the nature of my said Invention. and the manner
in which the same is to be performed. I desire it to be distinctly understood
that I do not claim the stripping roller itself, as it has been before in use; but
what I claim is, the peculiar system of giving at certain measured intervals of

page_text: time a to-and-fro or forward and backward movement to the stripping roller,
and the employment of a comb for the purpose of stripping it, so that after
the roller has revolved as long as required in close contact with the main card
cylinder, and effectually stripped and cleaned it, the roller shall be brought
back, and then stripped and cleaned by the comb.
In witness whereof, I, the said William Brown, have hereunto set my
hand and seal, this Nineteenth day of July, in the year of our Lord
One thousand eight hundred and sixty-one.

within-named William Brown, in
