PROVISIONAL SPECIFICATION.
Improvements in Woollen Condensers.
1, CHARLEY CLAY, of Luddenden Foot Mills, near Halifax, Yorkshire, Woollen
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to the double doffer condenser carding engine, which
doffers are provided with rings of card teeth leaving intervening spaces, the card
teeth on one doffer being opposite to the space on the other doffer. Both these
doffers work in contact with the ordinary "swift," the periphery of which is
covered with card teeth, but the combined doffers will strip all the fibre off the
swift.
In constructing a double doffer condenser according to my invention, I place in
contact with each doffer a stripper for stripping the fibre off the rings of the said
doffers in the form of detached slivers, which are afterwards conducted to a dividing
roller working in conjunction with another stripper employed to strip the detached
slivers from the stripper first mentioned. The divider and second stripper after-
wards conduct the slivers to a pair of rubbing belts, the axles of the rollers of such
belts being in a vertical line one above the other.
By attaching to each doffer the parts as above described, two sets of slivers are
rubbed into threads at the same time; and as two doffers and two sets of rubbers
are employed, it follows that there is a greater space between each thread than
would be the case if all the threads were formed by the same rubbers, consequently
re is more working or rubbing space for each thread. The threads are also
nder and more evenly formed, in addition to which the double doffers ensure all
the fibre being removed from the swift, whereby more even yarn is produced than
hitherto.

COMPLETE SPECIFICATION.
Improvements in Woollen Condensers.
I, CHARLEY CLAY, of Luddenden Foot Mills, near Halifax, Yorkshire, Woollen
Manufacturer, 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 has reference to the double doffer condenser carding engine, which
doffers are provided with rings of card teeth leaving intervening spaces, the card
teeth on one doffer being opposite to the space on the other doffer. Both these
doffers work in contact with the ordinary "swift," the periphery of which is
covered with card teeth, but the combined doffers will strip all the fibre off the
swift.
In constructing a double doffer condenser according to my invention, I place in
contact with each doffer a stripper for stripping the fibre off the rings of the said
doffers in the form of detached slivers, which are afterwards conducted to a dividing
roller, working in conjunction with another stripper employed to strip the detached
slivers from the stripper first mentioned. The divider and second stripper after-
wards conduct the slivers to a pair of rubbing belts, the axes of the rollers of such
belts being in a vertical line one above the other.
In order that my invention may be fully understood, I herein make reference to
the accompanying drawings illustrative thereof.

page_text: Fig. 1 shews my improvements applied to a condenser carding engine, and
Fig. 2 shews the gearing for giving rotary motion to some of the parts hereafter
described.
C
A is the swift of a condenser carding engine, with which work the double
doffers B and C having rings of card teeth thereon at equal distances apart, the
card teeth on one doffer being opposite the intervening spaces on the other doffer
so that the whole of the fibre is stripped off the swift by the said doffer, all arranged
in the ordinary manner. In combination with each ring doffer is a pair of
strippers a, a, and b, b', and dividing rollers c and d, the strippers a and removing
the fibre, in the form of parallel detached slivers, from the doffers B and C, whilst
the strippers a and remove such detached slivers from the strippers a and b and
place them into the grooves in the dividing rollers c and d which ensure the perfect
division or separation of the slivers before they enter between the condenser
rubbers e and The axles of the rollers of such rubbers are arranged in a vertical
line one above the other so that the slivers are brought into contact with the upper
and lower belts at the same time, whereby there is no reciprocatory movement of
the said slivers previous to the rubbing action, as is the case at present. The
condensed slivers, after leaving the rubbers, pass in the ordinary way through the
raddles g, h, and are wound upon the condenser bobbins k, l.
The condenser rubbers receive rotary motion from the shafts of the doffers by a
train of wheels D, and the strippers a¹ and and dividing rollers c and d receive
their motion from the strippers a and b, which are in turn driven from the opposite
side of the machine, or the parts may be driven by other suitable arrangement of
gearing.
By attaching to each doffer the parts as above described, two sets of slivers are
rubbed into threads at the same time, and as two doffers and two sets of rubbers are
employed, it follows that there is a greater space between each thread than would
be the case if all the threads were formed by the same rubbers, consequently there
is more working
or rubbing space for each thread. The threads are so rounder
and more easily formed, in addition to which the double doffers e
fibre being removed from the swift, whereby more even yarn is peed than
hitherto.
Having now particularly described and ascertained the nature of m
tion, and in what manner the same is to be performed, declare
claim is
The combination with the swift of a woollen condenser, of a pair o
with their accompanying sets of strippers, dividing rollers, and conde
the axles of such rubbers being in the same vertical line, all arranged
in the manner and for the purposes substantially as herein shewn and
