Improvements in Machinery for Condensing Slivers of Woollen,
Cotton, and other Fibres.
We BENJAMIN BOOTH, and JOSHUA BEAUMONT, of Armitage Bridge Mills near
Huddersfield, Yorkshire, Scribbling Engineers do hereby declare the nature of this
invention to be as follows:-
Our invention has reference to machinery employed in condensing or rubbing slivers
of fibre between reciprocatory "rubbers." In constructing a machine for the above
purpose, in accordance with our invention, we employ a series of pairs of rollers
arranged side by side, the speed of each succeeding pair of rollers being quicker than
that of the preceding pair, so that the slivers of fibre removed from the doffing
cylinder and passing between, such said rollers are drawn or draughted.
..
In addition to the series of pairs of rollers having a rotary motion, they have also
imparted to them a reciprocatory motion so that in addition to the fibre being drawn,
it is also rolled or rubbed into a slubbing or thread. In combination with these
revolving reciprocatory rollers we employ one or more pairs of rubbing belts between
which the slubbing passes after emerging from between the last pair of rollers, and
finally the slubbings are received by a cylinder or drum upon which they are
wound.
By employing pairs of rollers gaining in speed one upon the other, a draught is
given to the fibre, and when used in combination with reciprocatory rubbers a finer
slubbing or thread is produced thereby, than can be effected by the condensing
machinery as at present in use. It will be understood that the increased speeds of
the rollers are obtained by employing gear wheels of varying diameters.

Improvements in Machinery for Condensing Slivers of Woollen,
Cotton, and other Fibres.
We, BENJAMIN BOOTH! and JOSHUA BEAUMONT, of Armitage Bridge Mills, near
Huddersfield, Yorkshire, Scribbling Engineers, 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 :—
Our invention has reference to machinery employed in condensing or rubbing
slivers of fibre between reciprocatory "rubbers." In constructing a machine for the
above purpose, in accordance with our invention, we employ a series of pairs of rollers
arranged side by side, the speed of each succeeding pair of rollers being quicker than
that of the preceding pair, so that the slivers of fibre removed from the doffing
cylinder and passing betweeen such said rollers are drawn or draughted..
In addition to the series of pairs of rollers having a rotary motion, they have also
imparted to them an end wise or reciprocatory motion, so that in addition to the fibre
being drawn, it is also rolled or rubbed into a slubbing or thread. In combination
with these revolving reciprocatory rollers we employ one or more pairs of rubbing
belts between which the slubbing passes after emerging from between the last pair of
rollers and finally the slubbings are received by a condenser bobbin or drum upon
which they are wound.
Such being the nature of our said invention, we will now describe the same more
fully, and for that purpose make reference to the accompanying sheets of drawings
TDCI

page_text: illustrative thereof, wherein Fig. 1 is cross section of our improved combination
mechanism, Fig. 2 is a side view shewing how we drive the several parts, and Fig. 3
is plan view of our improved machinery. A represents the framework of the machine
and B a portion of the carding cylinder or doffer from which the fibre is stripped by
the toothed rollers and D. Letter E represents a series of revolving rollers, the
rotary motion of each pair increasing on the preceding pair, such varying speeds
being obtained by the arrangement of toothed wheels F, which contain fewer teeth
necessary for the increased speeds, so that the sliver passing between these rollers is
drawn or draughted, as will be well understood. In addition to these rollers having
rotary motion and gaining in speed one on another, as described, we impart to them
an endwise or reciprocatory motion for the purpose of rolling or rubbing the sliver
into a thread, the end wise motion of such rollers being obtained by means of
eccentrics G and H working within yokes I and J attached to the side brackets L by
which the axles of the rollers are carried, the usual form of broad toothed wheels M
being employed to allow for the end wise motion of the rollers. After the sliver has
been drawn and rolled by the drawing rollers E, it is received by one or more pairs
of endless rubbers N which also have rotary and end wise motion for the purpose of
more effectually rolling and rubbing the sliver into a more perfect thread or
slubbing O, after which the said threads are wound upon the condenser bobbins P to
receive the subsequent processes of manufacture.
Instead of the rubbing belts N operating upon the sliver after the rollers E, such
said rubbers may operate upon the sliver before the rollers E, as shewn in Fig. 4.
By employing pairs of rollers gaining in speed one upon the other, a draught is
given to the fibre, and when used in combination with reciprocatory rubbers a finer
slubbing or thread is produced thereby than can be effected by the condensing
machinery at present in use.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The use of reciprocating drawing rollers E in combination with one or more pairs
of rubbing belts arranged in the manner and employed for the purpose substantially
as shewn and described.
