Patent Agent, for the Invention of "IMPROVEMENTS IN MACHINERY OR.
APPARATUS FOR STRIPPING OR CLEANING THE DRUMS AND ROLLERS OF CARDING
ENGINES AND OTHER MACHINES IN WHICH ROLLERS COVERED WITH CARD TEETH

thur, in the Republic of Switzerland.
Sealed the 1st June 1860, and dated the 29th December. 1859.
PROVISIONAL SPECIFICATION left by the said Henry Bernoulli Barlow
at the Office of the Commissioners of Patents, with his Petition, on
the 29th December 1859.
I, HENRY BERNOULLI BARLOW, of the City of Manchester, Patent Agent,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR STRIPPING OR CLEANING THE DRUMS AND ROLLERS
OP CARDING ENGINES AND OTHER MACHINES IN WHICH ROLLERS COVERED WITH CARD
TEETH ARE EMPLOYED," a communication to me from abroad by H. Rieter, of
Winterthur, in the Republic of Switzerland, to be as follows:-
The nature of these improvements consist in an apparatus for continually
cleaning or stripping the main drum or other rollers of carding engines for
wool, cotton, tow, silk waste, or other fibrous substances, and it is also appli-

page_text: cable to other drums or rollers covered with either similar or stronger teeth.
The principal part of such apparatus is a small roller, having one or more
narrow rows of teeth, wires, or bristles set in a spiral or helical line upon it,
and revolving close to the roller or drum to be cleaned in such a manner as
to brush the particles of cotton dust and other impurities out of the teeth of
the said roller or drum. This is done by letting the small stripping roller
rotate in the opposite way to the large drum, so that the surfaces which are
in contact move in the same direction, but with different velocities. The fibres
thus taken out of the large drum may then be taken from the stripping roller
by a second roller, and conveyed back again to the main drum. To effect
this object, this second roller is covered with card cloth or fillet, similar to
that commonly employed in carding engines, and revolving in contact with
both the large drum and the stripping roller, but slower than either, so as to
enable the main drum to draw the fibres out of its teeth.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Bernoulli Barlow in the Great Seal Patent Office
on the 27th June 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BERNOULLI BARLOW, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of December, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Bernoulli Barlow, Her special licence. that I, the said Henry
Bernoulli Barlow, my executors, administrators, and assigns, or such others
as I, the said Henry Bernoulli Barlow, 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 Inven-
tion for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR STRIPPING OR CLEANING
THE DRUMS AND ROLLERS OF CARDING ENGINES AND OTHER MACHINES IN WHICH
ROLLERS COVERED WITH CARD TEETH ARE EMPLOYED," a communication to me
from abroad by H. Rieter, of Winterthur, in the Republic of Switzerland,
upon the condition (amongst others) that I, the said Henry Bernoulli Barlow,

page_text: ·
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 Henry Bernoulli Barlow, 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 these improvements consists in an apparatus for continually
cleaning or stripping the main drum or other rollers of carding engines for wool,
cotton, tow, silk waste, or other fibrous substances, and it is also applicable to
other drums or rollers covered with either similar or stronger teeth. The prin-
cipal part of such apparatus is a small roller, having one or more narrow rows of
teeth, wires, or bristles, set in a spiral or helical line upon it, and revolving
close to the roller or drum to be cleaned, in such a manner as to brush the
particles of cotton dust and other impurities out of the teeth of the said roller
or drum. This is done by letting the small stripping roller rotate in the
opposite direction to the large drum, so that the surfaces which are in contact
move in the same direction but with different velocities. The fibres thus
taken out of the large drum may then be taken from the stripping roller by a
second roller and conveyed back again to the main drum. To effect this
object, this second roller is covered with card, cloth or fillet similar to that
commonly employed in carding engines, and revolving in contact with both the
large drum and the stripping roller, but slower than either, so as to enable
the main drum to draw the fibres out of its teeth.
And in order that the Invention may be fully understood and readily carried
into operation, I will proceed to describe the accompanying Sheet of Draw-
ings, reference being had to the figures, letters, and arrows marked thereon.
A is part of the main drum of an ordinary carding engine for cotton, and
B the licker-in; C is the stripping roller, on the surface of which is fixed a
narrow strip of wire brush or bristles, in a helical line; this roller revolves in
the adjustable bearings C¹; the circumference of the stripping roller C, revolves
at a greater velocity than the circumference of the main drum, but both
surfaces at their point of contact move in the same direction, as indicated by
the arrows; D is a small roller covered with common card fillet, which catches
the longer fibres that may have been taken from the main drum by tho

page_text: stripping roller, and delivers them again to the main cylinder; the roller D
revolves in the adjustable bearings D'. The rollers B, C, and D, are driven
by the strap E, from a pulley on the axle of the main drum, as clearly shewn
in the Drawing.
Having thus stated the nature of the Invention communicated to me, and
described a convenient arrangement of parts for performing the same when
applied to an ordinary carding engine, I. wish it to be understood. that the
stripping roller C may be applied for cleaning rollers covered with card teeth
employed in any other description of machine, and that two or more narrow
strips of wires or bristles may be coiled around the stripping roller C. In
some cases it may be advantageous to employ two or more stripping rollers,
or the stripping roller may be placed in a different position to that shewn in
the Drawing. I therefore do not limit myself to the details given, but what
I claim is the exclusive use of the stripping roller C, having one or more
rows of teeth of wires or bristles set in a spiral or helical line on its circum-
ference for the purpose set forth.
In witness whereof, I, the said Henry Bernoulli Barlow, have hereunto
set my hand and seal, this Twenty-sixth day of June, in the year
of our Lord One thousand eight hundred and sixty.
