We JOHN SELLERS and RICHARD SELLERS of the firm of Robert Sellers and
Sons Prospect Mills Scholes, Cleckheaton, in the county of York, Card Manu-
facturers, do hereby declare the nature of our invention for "IMPROVEMENTS IN
CONDENSER STRIPPER RINGS AND IN APPARATUS EMPLOYED IN THE MANUFACTURE
THEREOF" to be as follows:-
This invention relates to certain improvements in condenser stripper rings and
has for its object the construction of the rings in such a manner, that the wide
blank space usually found between the teeth at the place where the rings are jointed
is obviated.
Hitherto the foundation for the rings has been made in long lengths, set with
card teeth in ordinary machines, and then cut into lengths and sewn together, by
which method a blank space is left between the teeth at the junction.
According to our invention we splice the rings before they are "set," and in order
to set the spliced rings with card teeth, we add two additional fluted rollers placed
above the ordinary fluted rollers and bend the crooker arms so as to project into
the interior of the ring for operating on the teeth The front additional roller is
cut away in the centre to below the depth of the flutes for clearance of the crowns
of the teeth, and the back roller is geared with the taking up shaft, mounted in
slotted brackets and fitted with two narrow fluted rollers which are kept in contact
by means of springs with each side of the ground of the stripping ring.
The teeth are set in the ground for a short distance and then removed, when
the remainder are set, and on the removal of the ring from the machine, the teeth
are replaced in the holes, thus completing the stripper ring with card teeth.

We, JOHN SELLERS, and RICHARD SELLERS of the firm of Robert Sellers and
Sons, Prospect Mills, Scholes, Cleckheaton, in the County of York, Card Manu-
facturers, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to certain improvements in condenser .stripper rings, and
has for its object, the construction of the rings in such a manner, that the wide
blank space, usually found between the teeth at the place where the rings are
jointed, is obviated.

Hitherto the general method has been for the foundation to be made in long
lengths, set with card teeth, in ordinary machines, and then cut into lengths and.
sewn together, by which method a blank space is left between the teeth at the
junction.
The invention consists in splicing the rings before they are set with card teeth,
adding to the ordinary machine two additional fluted rollers, and arranging the
crooker arms so as to project into the interior of the rings for operating on the teeth
as they are set.
In the accompanying drawings, Fig. 1 represents such portions of the front
elevation of an ordinary card setting machine as are required to describe our
improvement, which is added thereto. Fig. 2 is a section through line a. b.—Fig. 3
a plan of the crooker arms shewing the direction in which they are bent, and Fig. 4
an enlarged view of the additional rollers.
The brackets A, commonly called the inclines of the machine, are of the usual
construction, except that provision is made for the two additional fluted rollers B
and C; the former roller is reduced in diameter to below the depth of the flutes for
clearance of the crowns of the teeth, and the shaft is extended to the outside of the
framework for the reception of a pulley D, around which is wound a cord having
a weight attached to the end, for the purpose as hereinafter described.
The narrow fluted rollers C are larger in diameter, and the shaft is kept in the
journals formed in the brackets A, by means of the springs E which are mounted
on the top shaft S, and when brought over to the position shewn, keep the shaft
and rollers in the requisite position; or in addition to the said springs, the side
bars F may be used as a support or stay to the shaft of the narrow fluted rollers C,
the side bars being held against the shaft journals by spiral springs.
The shaft of rollers C is geared with the take up shaft H by the spur wheel and
pinion G and G₁; the said shaft H being operated in the usual manner, is fluted
between the brackets at H, and in contact with the last mentioned roller, we use
the usual narrow rollers H2 mounted on the brackets and supported by the square
shaft in the usual manner.
The rings for the foundation may be made of leather, vulcanized indiarubber, or
other well known material, and are jointed and spliced before the card teeth are

page_text: set, and in order to put the spliced rings into the machine, the springs E and side
bars are moved so as to liberate the narrow fluted rollers C; the ring is then
placed upon the rollers, which are put back into the journals and secured as before
described; and the ring is also placed between the roller H and the narrow
rollers H, which, in conjunction with the additional rollers B and C, cause the ring
to travel as the card teeth are being set; the weighted cord around the pulley D
turning the shaft and rollers B.
The teeth are set in the ground by the machine in the ordinary manner, and bent
to the necessary angle by the crookers K, which are operated in the usual manner,
and bent as shewn so that the rings can be put into or removed from the machine,
without having occasion to disturb the same when once set; thereby ensuring the
teeth of all the rings being bent to the same angle.
On commencing a ring, when a few rows of card teeth are set, they are removed
from the foundation, and the remainder set, when on the removal of the ring from
the machine the teeth are replaced in the holes; thus completing the stripping
ring with card teeth without having a blank space between the teeth at the
junction, as is the case when the foundation is sewn or jointed in the usual
manner.
We are aware that attempts have been made to set jointed stripper rings with
card teeth, but the arrangement of the crookers have been such, that it has been
necessary to remove one of them every time a ring was put into, or removed from
the machine; thereby necessitating much labour and a difficulty in obtaining the
same angle to the teeth in the various rings.
Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:-
Card setting machines in which additional rollers B and C are fitted, and the
crooker arms K bent for the purpose as herein before described.
Card setting machines fitted with additional rollers B and C, and driven by
gearing G and G', all arranged substantially in the manner and for the purpose as
hereinbefore described.
