PROVISIONAL SPECIFICATION.
Improvements in or relating to Wool Rubbing and Condensing
Apparatus.
We, JOSEPH HENRY ROBERTSHAW, of 14 Union Street, Ravensthorpe near
Dewsbury in the County of York, Scribbling Overlooker, and WILLIAM
HARTLEY, JOHN HARTLEY, and LISTER HARTLEY, trading as Hartley
Brothers of Bridge Street Leather Works, Ravensthorpe aforesaid, Curriers
and Leather Merchants, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to improvements in the rollers of condensers for use in the
woollen trades and in rubbers therefor.
Hitherto it has been customary to make the iron or wooden rollers of the
machine known in the woollen trade as the condenser, parallel and to cover it or
them with leather, which coverings are, usually termed "condenser rubbers."
Now the object of the present invention is to construct either the roller or its
"rubber" so as to prevent the threads operated upon from running into each other,
and to prevent the "rubbers" from puckering and at the same time producing a
more even thread.
According to this invention we either make the rollers undulated or with several
curved parts formed in its length or with projections or rings at suitable distances
apart; or on the inner surface of the rubber we place or fix any desired number of
strips of any suitable material such as for instance, leather, felt, paper, woollen or
cotton material, india-rubber or it or their equivalents. The strips may be of any
suitable width and thickness and are fixed on the rubbers parallel to each other at
suitable distances apart and when the rubbers are fixed on the rollers, the strips
are arranged to pass or wrap round the periphery of the roller at or about a right
angle to its length. The strips may also be bevelled on each edge.
When an undulated or curved roller is used a rubber with or without the above
mentioned strips may be used, but when the strips are used we prefer, though not
necessarily so, to employ a roller with a plain or parallel periphery.

Improvements in or relating to Wool Rubbing and Condensing
Apparatus.
We, JOSEPH HENRY ROBERTSHAW, of 14 Union Street, Ravensthorpe, near
Dewsbury, in the County of York, Scribbling Overlooker, and WILLIAM
HARTLEY, JOHN HARTLEY, and LISTER HARTLEY, trading as Hartley
Brothers, of Bridge Street Leather Works, Ravensthorpe aforesaid, Curriers

page_text: and Leather Merchants, 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 improvements in wool rubbing and condensing
apparatus and relates particularly to the rollers of the condensers and in rubbers
therefor, which are employed for rubbing or reducing the "slivers" of wool or
other materials into threads.
Hitherto it has been customary to make the iron or wooden rollers of the
machine known in the woollen trade as the condenser, parallel, and to cover it or
them with leather, which coverings are usually termed "condenser rubbers."
Now the object of the present invention is to construct either the roller or its
"rubber
so as to prevent the threads operated upon from running into each other,
and to prevent the "rubbers" from puckering and at the same time producing a
more even thread.
"
In the drawings hereunto annexed we have given several examples of how this
invention may be carried into practice without departing from its principle.
The framework and other working parts of the wool rubbing and condensing
apparatus being of well known construction are omitted from the drawings.
Fig. 1 is an end elevation and Fig. 2 a sectional elevation of the condenser
rollers and rubbers constructed according to this invention.
Figs. 3 to 7 are sectional or other elevations of rollers constructed according to
this invention.
Like parts in all the views are marked with similar letters of reference.
A, A, A, A, A¹, A', A', are the condenser rollers which may either be
constructed with perfectly plain and parallel peripheries, say, as shown at. Figs. 1
and 2, or with their peripheries curved or undulated at one, two, three or more
parts a extending in a longitudinal direction, say as shown at Fig. 6.
When this
is the case the lower rollers A' would have their peripheries curved or undulated in
the opposite direction, that is to say if the curves or undulations a of roller A were
concave, the convex portions a' of roller A' would be arranged to correspond with
the concave portions of roller A., or vice versa, but at the same time to permit of a
rubbing action taking place. Or the peripheries of the rollers A and A¹ may be
curved or corrugated say as at Fig. 5. Or perfectly plain and parallel rollers A A'
may be employed as at Figs. 1 and 2, or a parallel roller, such as shown at Figs. 3
or 4 may be employed, having any desired number of rings or projections a² fixed
to or formed on the periphery either with bevelled edges as at Fig. 3 or with
straight edges as at Fig. 4. When the rings or projections a are fixed to the
periphery of the rollers A, A', they may be formed of any suitable material such
as for instance leather, felt, paper, woollen or cotton material, india-rubber, or it or
their equivalents.
Bis the rubber which is usually formed of leather with its ends scarfed together
to form an endless band when paid over and around the rollers A A', as shown at
Fig. 1. On the inner side of the rubber B is placed or fixed say in a longitudinal
direction any desired number of strips 6' of any suitable material such as for
instance, leather, felt, paper, woollen or cotton material, india-rubber, or it or their
equivalents. The strips may be of any suitable width and thickness and are
fixed on the rubbers B say parallel to each other at suitable distances apart and
when the rubbers are placed in position on the rollers, the strips 6 are arranged to
pass or wrap partially round the periphery of the rollers A. A₁ at or about a right
angle to its length or axis. The strips b' may also be bevelled or straight on
each edge.
When projections are formed on the periphery of the rollers A A¹ the
projections on the rubbers B may be, though not necessarily so, dispensed with
or rice versa. Instead of the herein described rollers being mounted in bearings
capable of being reciprocated only to and fro, they may, when desired be so
mounted in their bearings so as to be capable of adjusting themselves to the varying

page_text: thicknesses of material whilst at work, springs or equivalent means being employed
for retaining them to their work.
It will readily be understood that the same results may be attained by either
forming the projections and recesses or hollows on the rollers A A' or on the
rubbers themselves, and by forming or providing for a concave or series of concave
portions to be formed in the peripheries of the rollers and rubbers when at work,
the threads are prevented from running into each other, and the rubbers are also at
the same time prevented from puckering, and a more even thread is produced.
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 :-
1. The improvements in or relating to wool rubbing and condensing apparatus
consisting essentially of the means such as herein described for producing the series
of projections and concaves or recesses on the surface of the rubbers when at work
as and for the purposes set forth.
2. In wool rubbing and condensing apparatus such as herein described and
illustrated the rollers such as A. A¹ having an irregular periphery formed by
providing therein one or more concaves or recesses, as and for the purposes set
forth.
3. In wool rubbing and condensing apparatus such as herein described and
illustrated, the rollers such as A A¹ having a series of rings or projections such
as a² fixed to it or their peripheries as and for the purposes set forth.
4. In wool rubbing and condensing apparatus such as herein described and
illustrated the rubber B having a series of say longitudinal strips b' fixed say
parallel to each other on the inner surface of the rubber so that when the rubber is
at work, the said strips will be at or about a right angle to the length or axis of the
rollers as and for the purposes set forth.
5. The combination in wool rubbing and condensing apparatus, of the rollers A A¹
having either plain and parallel peripheries or irregular peripheries formed
substantially as herein described and illustrated with rubbers 13, with or without
projections 6 formed on or attached to their inner surfaces, as and for the purposes
herein set forth.
