Improvements in Condenser Carding Engines.
I, ARTHUR HARDWICK, Foreman of Spen Valley. Carpet Works, Liversedge,
in the County of York, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in condenser carding engines, the
object being to so construct such engines, that a greatly increased quantity of
fibre and better slivers are doffed from the cylinder, and there is less liability of
one sliver mingling with or coming into contact with another as was heretofore
the case when the slivers were removed adjacent to one another. The invention
consists in so arranging and combining the doffers and condensers or rubbers with
the cylinder that as the fibre is removed in the form of slivers by the doffing
rings, one portion or end is doffed at one point or plane, and the adjoining portion
or end is doffed at a lower or higher plane or point on the cylinder.
According to this invention I employ three ring doffers one above the other
and each doffer has its own set of rubbers or condensers. The top ring or doffer
removes the fiber in the form of a sliver from the cylinder, and the bottom ring
or doffer removes a like sliver from the adjoining portion of the cylinder, whilst
the second or middle ring or doffer removes a sliver from a portion of the cylinder
adjoining that removed by the bottom ring or doffer. By the construction above
described it will be seen that the cylinder is effectively and thoroughly doffed and
at the same time the several slivers are kept as far as possible from one another.

Improvements in Condenser Carding Engines.
I, ARTHUR HARDWICK, Foreman of Spen Valley Carpet Works, Liversedge,
in the County of York, 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 improvements in condenser carding engines, the

the case when the slivers were removed adjacent to one another. The invention
consists in so arranging and combining the doffers and condensers or rubbers with
the cylinder that as the fibre is removed in the form of slivers by the doffing
rings, one portion or end is doffed at one point or plane, and the adjoining portion
or end is doffed at a lower or higher plane or point on the cylinder.
Such being the nature and object of my said invention the following is a com-
plete description of same, reference being had to the accompanying drawings, in
which:-
Fig. 1 is an end view of so much of a condenser carding engine as is required
to illustrate this invention and shewing the positions of the respective doffers.
Fig. 2 is a diagramatical view shewing the positions and arrangements of the
respective rings of the three doffers.
According to this invention I employ three ring doffers 1, 2, and 3 one above
the other and each doffer has its own set of rubbers or condensers 4, 5 and 6.
The first ring 8 of the top doffer 1 removes the fibre in the form of a sliver from
the cylinder 7 and the first ring 9 of the bottom doffer removes a like sliver from
the adjoining portion of the cylinder 7 whilst the first ring 10 of the middle
doffer 2 removes a sliver from a portion of the cylinder 7 adjoining that removed
by the first ring 9 of the doffer 3, and the next or second ring 11 of the top
doffer 1 removes a sliver from the portion of the cylinder adjoining the last men-
tioned one removed by the first ring 10 of the doffer 2 and so that the whole
surface of the cylinder 7 is doffed or stripped in the form of slivers, the slivers
stripped by the rings on one of the doffers being kept a considerable distance apart.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is: -
(1) A condenser carding engine having three doffers 1, 2, 3 each provided with
its own rubbers and the doffing rings of the doffers arranged in the manner and
for the purpose herein described.
(2) The cylinder 7 having three doffers 1, 2, 3 with their rings arranged in the
manner and for the purpose herein described and substantially as illustrated by
the annexed drawings.
