Improvements in Woollen Condensing Machinery.
We ALFRED MARSDEN and ALFRED LAYCOCK both Woollen Manufacturers, and
ALFRED STEPHENSON, Carding Engineer, all of Tower Mills, Turnbridge, Huddersfield
in the County of York, do hereby declare the nature of this invention to be as
follows:-
Our invention consists in the construction and employment of an additional pair of
rubbers which operate upon the thread immediately it passes from the rubbers
hitherto employed.
pair
To carry out our invention we pass the fibres after leaving the cards first through
the ordinary single or double rubbered or double doffer condensers, and up to this
stage the process and mechanism are precisely similar to those hitherto in use, except
that narrower rubbers (between the centre lines of the rollers) may be employed.
After passing through the first rubbing process the fibre passes to another of
rubbers the rollers of which are mounted in the same horizontal plane as the first
pair. The second pair of rubbers is geared to run at a greater speed than the first
pair whereby a slight drawing action takes place between the two pairs of rubbers and
this action combined with the quicker speed of the second rubbing process produces a
finer, rounder, and more solid thread than is found to result in the process hitherto
in use.
The relative speeds of the two pairs of rubbers is regulated to suit different
classes of materials by means of change wheels adjusted to the roller spindles of the
rubbers.
As before stated we employ rubbers narrower between the centre lines of the rollers
than those hitherto in use, whereby leathers of the required size of more uniform
surface and containing fewer faulty places can be obtained than when leathers of
larger size are required, the resulting work is therefore more evenly rubbed and
uniform, and the thread being more symmetrical and finer, a larger quantity is
contained on each condenser bobbin.

Improvements in Woollen Condensing Machinery.
WO ALFRED MARSDEN and ALFRED LAYCOCK both Woollen Manufacturers, and
ALFRED STEPHENSON, Carding Engineer, all of Tower Mills, Turnbridge, Huddersfield
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 :-
Our invention consists in the construction and employment of an additional pair of
rubbers mounted upon a condensing machine for the purpose of further operating
upon the woollen thread immediately after it leaves the first pair of rubbers.
To carry out our invention we cause the fibres, after leaving the cards, to pass first
through the ordinary single, or double rubbered, or double doffer condensers, and up
to this stage the process and mechanism are precisely similar to those hitherto in use,
except that shorter rubbers (measured between the centres of their rollers) may be
employed. The fibres after being rolled and pressed together into the form of a
thread by the first pair of rubbers, then pass to a second pair, the rollers and leathers
of which are mounted and operate by preference in the same horizontal plane as the
first nair

page_text: This second pair of rubbers is rotated and reciprocated horizontally by similar
gearing to that hitherto employed for the actuation of rubbers, but is by preference
geared to run at a greater speed than the first pair, whereby a slight drawing action
takes place between the two pairs of rubbers, and this drawing combined with the
quicker speed and more thorough treatment caused by the use of the extra pair of
rubbers, results in the production of a finer, rounder, and more solid thread, than can
be produced by the single rubbing process hitherto employed.
The relative speeds of the two pairs of rubbers are regulated to suit different classes
of materials by means of change wheels interposed in the gearing by which the rubbers
are driven.
As hereinbefore stated we are enabled to use rubber leathers shorter, and therefore
of smaller size, than those hitherto in use, whereby leathers of the required size, of
more uniform surface, and containing fewer faulty places can be obtained than when
the leathers are required to be of larger size; the work produced by the rubbers is
therefore more uniform and evenly rubbed, and the resulting thread being finer and
more symmetrical in form, a larger quantity is contained upon the condenser bobbins
than has hitherto been practicable.
In order to enable iny invention to be fully understood I will proceed to describe
the same with reference to the accompanying drawings in which Figure 1 represents
a sectional elevation of a sufficient portion of a woollen condensing machine to illustrate
our invention, and Figure 2 represents a plan view of the same. Similar letters refer
to similar parts in both figures.
The first pair of rubbers which receives the fibres from the cards is represented
at A. A. From these rubbers the threads pass between guide wires which project
downwards from the guide rail G, whereby the threads are kept apart and prevented
from running together.
The guide rail G is suspended between the two pairs of rubbers by quadrants
jointed to the pillars H which are fixed upon the side frames F of the machine, and by
means of a handle the guide rail can be raised to allow access to the threads between
the rubbers.
The threads after passing under the guide rail G are received between the leathers
of the second rubber B. B. by which they are further formed and consolidated into a
round thread, and from these second rubbers the threads M and N are conducted to
the surface rollers and J, half the number (alternate threads) are received by the
upper surface roller C, being held apart by guide wires upon the rail E; the lower
threads N pass between guide wires upon the rail L to the surface roller J. The
threads pass from the surface rollers on to the condenser bobbins D and J, which are
actuated by friction with their respective surface rollers in the usual manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
claim is,
1. In a woollen condensing machine, a second pair of rubbers to receive and
operate upon the woollen thread after it has been operated upon by the first pair of
rubbers, substantially in the manner described and represented
2. In combination with the rubbers of an ordinary condensing machine, second or
extra pairs of rubbers to follow each first pair in operating upon the thread after the
first rubbing process, in the manner substantially as described and represented.
3. The general arrangement of rubbing mechanism applied to a woollen condensing
machine as described and represented in the accompanying drawings.
