Sealed the 24th June 1870, and dated the 21st March 1870.
PROVISIONAL SPECIFICATION left by the said Samuel Brooke at the
Office of the Commissioners of Patents, with his Petition, on the
21st March 1870.
I, SAMUEL BROOKE, of Brighouse, in the County of York, Card
Maker, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN THE DOFFERS OF CONDENSING CARDING ENGINES AND MEANS OR
APPARATUS FOR EFFECTING THE SAME," to be as follows:-
This Invention relates to machinery or apparatus for carding wool or
other fibrous substances, for which Letters Patent were granted to me,
dated July 2nd, 1869, No. 1997. In the Specification of one part of the
said Invention grooves are described as being formed in the card.clothing

page_text: of the doffer cylinder by depressing the card teeth, and then intro-
ducing rings formed of wire or metal to fill up the grooves to form
divisions in the said doffer clothing. Now I have found it preferable
to remove the said card teeth out of the said grooves instead of
depressing them, by cutting them out close to the leather or other
material in which they are set. This I accomplish by means of a pair
of nippers, shears, or cutters of suitable size and form, mounted upon
a carriage which is capable of being set in proper position in front of
the doffer, and operated by a cam or equivalent means, so as to cut out
a portion of the card teeth, then the doffer is turned forward a suitable
distance and the nippers again operated to out out another portion of
the card teeth when the doffer is again turned, and so on, the nippers
and doffer being alternately operated by intervals or intermittently,
until a groove is formed entirely around the said doffer by cutting out
the card teeth, the carriage is then moved on a shaft or frame in front
of the doffer a certain distance, and another groove is cut or formed
in like manner, and so on, until the whole series of grooves are thus
formed. In order to set the carriage in any desirable position according
to the distance required for the grooves to be apart from each other,
I have a screw spindle passing through a nut in the carriage, and a
handle fixed on one end thereof, with an index plate fixed to the frame-
work, so that the distances may be properly calculated and divided
according to the special requirements of the case. The wire or metal
rings are then inserted, as explained in the Specification above referred
to, whereby they rest solid on the leather or other material in which
the card teeth are set, so that the said rings are firm and will last as
long as the card teeth.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of March, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Samuel Brooke, Her special licence, that
I, the said Samuel Brooke, my executors, administrators, and assigns, or
such others as I, the said Samuel Brooke, my executors, administrators,
and assigns, should at any time agrec 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 THE DOFFERS OF CON-
DENSING CARDING ENGINES AND MEANS OR APPARATUS FOR EFFECTING THE SAME,"
upon the condition (amongst others) that I, the said Samuel Brooke,
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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Brooke, do hereby declare
the nature of 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, and accompanying Sheet of Drawings (that is
to say):
This Invention relates to machinery or apparatus for carding wool or
other fibrous substances, for which Letters Patent were granted to me,
dated the Second day of July, One thousand eight hundred and sixty-nine,
and No. 1997.
In the Specification of one part of the said Invention grooves are
described as being formed in the card clothing of the doffer cylinder by
depressing the card teeth, and then introducing rings formed of wire or.
metal to fill up the grooves to form divisions in the said doffer clothing.
Now I have found it preferable to remove the said card teeth out of
the said grooves instead of depressing them, by cutting them out close
to the leather or other material in which they are set. This I accom-
plish by means of a pair of uippers, shears, or cutters of suitable size
:

proper position in front of the doffer, and operated by a cam or equivalent
means so as to cut out a portion of the card teeth, when the doffer is again
turned, and so on, the nippers and doffer being alternately operated by
intervals or intermittently until a groove is formed entirely around the said
doffer by cutting out the card teeth. The carriage is then moved on a
'shaft or frame in front of the doffer a certain distance, and another groove
is cut out or formed in like manner, and so on until the whole series of
grooves are thus formed. And in order to set the carriage in any
desirable position according to the distance required for the grooves to
be apart from each other, I have a screw spindle passing through a nut
in the carriage and a handle fixed on one end thereof, with an index
plate fixed to the framework, so that the distances may be properly
calculated and divided according to the special requirements of the case.
The wire or metal rings are then inserted, as explained in the Specifi-
cation referred to, whereby they rest solid on the leather or other material
in which the card teeth are set, so that the said rings are firm and will
last as long as the card teeth.

page_text: in the slide bed, and turned by a handle or wheel applied to one end.
The cutters are set in proper position by means of a divided scale J
temporarily fixed in a groove of the bed, which scale is changeable or
capable of being changed for other scales differently divided, as may be
required. Or an index plate may be fixed to the frame and a pointer
fixed on or moved by the screw shaft for effecting the proper setting of
the cutters. K is another shaft arranged parallel with the former or
On
screw shaft and supported in brackets K' fixed on the slide bed.
this shaft is carried and driven thereby a bevel wheel L, which is in gear
with another bevel wheel L' fixed on a short shaft L, which is supported
at one end in a bracket L³ fixed to the carriage, and at the other end in a
boss on the slide plate D². On this shaft L' is a cam M, which by
rotation thercof operates the cutters or opens them ready for cutting,
and a bow spring N presses them together again, causing them to cut
the card teeth out from the leather or other material to form the grooves.
P is a screw spindle passing through a nut P¹ on the slide plate D² for
placing the cutters to the proper position or depth in the card clothing,
and which is operated by the handle P³. P³ is an adjusting screw for
setting the cutters to card clothing. R is a spur wheel fixed on the
doffer shaft gearing into a spur pinion R' attached to a ratchet wheel R³,
both running loose on a stud R³ set fast in a slot plate R' which is fixed
to the framework. S is a lever hinged on the stud R³ carrying a catch S¹,
which takes into the ratchet wheel R³, and on the top of this lever is
set fast a joint piece S³, to which is connected a rod S³ attached by clip
strap to an eccentric S* fixed on the shaft K, by which rotary motion is
given to the doffer intermittently or at intervals, alternating with the
action of the cutters, so that when they are cutting or closing, the doffer
cylinder is at rest, and when they are opening the cylinder is being moved
forward and the card teeth enter in betwixt the cutters ready to be cut
out at the next closing of the said cutters.
Having thus described the nature of my said Invention, and shewn
by Drawings how the same is to be or may be performed, I would have
it understood that I do not confine myself to the precise details as herein
Invention
described and shewn by the Drawings; but what I claim as my
is,-
Firstly. The cutting out of the card teeth to form grooves in the card

page_text: Secondly. The means or apparatus for effecting the same in manner
substantially as herein described and shewn by the accompanying
Drawings.

In witness whereof, I, the said Samuel Brooke, have hereunto set
my hand and seal, this Nineteenth day of September, in the year 5
of our Lord One thousand eight hundred and seventy.
