PROVISIONAL SPECIFICATION.
Improvements in or relating to Condensers for Preparing Fibrous
Materials.
We, BENJAMIN ALFRED DOBSON, Machine Maker, of Kay Street Works,
Bolton, in the County of Lancaster, and WILLIAM ASHFORTH OPENSHAW,
Cotton Waste Spinuer, of Hill Fold Mills, Astley Bridge, Bolton aforesaid, do
hereby declare the nature of this invention to be as follows:-
Our improvements relate to that portion of the condenser where the sliver is
wound on the bobbin and consists chiefly in the substitution of a number of small
bobbins or tubes in place of a single long bobbin or a single long bobbin and two
small end or waste bobbins as at present.
These bobbins may or may not have flanges at their ends and are driven from
the surface of a roller or drum or any convenient number of rollers or drums in
any suitable arrangement. The bobbins are preferably held in position by suitable
guides or brackets attached to any stationary part of the machine and in cases
where the bobbins have no flanges a quick traverse guide is applied for the purpose
of cross winding and so firmly building the ends.
We do not bind ourselves to the number of bobbins to be used in one machine as
they may be varied according to the number of ends from the condenser.
By the use and application of these improvements we save a considerable amount
of waste and time and largely increase the production.

Improvements in or relating to Condensers for Preparing Fibrous
Materials.
We, BENJAMIN ALFRED DOBSON, Machine Maker, of Kay Street Works,
Bolton, in the County of Lancaster, and WILLIAM ASHFORTH OPENSHAW,
Cotton Waste Spinner, of Hill Fold Mills, Astley Bridge, Bolton aforesaid, 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:-
Onr improvements relate to that portion of the condenser where the sliver is
wound on the bobbin and consist chiefly in the substitution of a number of small
bobbins or tubes in place of a single long bobbin or a single long bobbin and two
small end or waste bobbins as at present.
These bobbins may or may not have flanges at their ends and are driven from
the surface of a roller or drum or any convenient number of rollers or drums in
any suitable arrangement. The bobbins are preferably held in position by suitable
guides or brackets attached to any stationary part of the machine and in cases
where the bobbins have no flanges a traverse guide is applied for the purpose of
cross winding and so firmly building the ends.

page_text: And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Figure 1 is a side sectional elevation and Fig. 2 a plan of a condenser to which
our improvements have been applied.
In these views, a designates the doffer, b the doffer comb, c the sliver, d the
dividing roller, ee the leather aprons or rubbers, f the funnel guides fixed on the
traverse rod g, the drum which is driven. in the usual way (not shown), i is a bevel
gear fixed on the drum axle and which drives by a gear j a disc k, the crank
pin on which transmits motion to a slotted lever I fixed on the traverse guide
rod g.
"
All the foregoing parts may be of the usual or any convenient construction and
in themselves form no part of our present improvements, which consist in the
substitution of the series of small bobbius m for the single long bobbin usually
employed either with or without the two small end or waste bobbins.
These bobbins m rest upon and are rotated by the drum h, or it might be by a
series of two or more drums, and the pivots of each bobbin m enter and are
maintained in position by open slots in guides n carried by arms n' fixed adjustably
on a shaft o supported in bearings in a bracket p secured to the frame g.
We do not bind ourselves to the number of bobbins or tubes to be used in one
machine as they may be varied according to the number of ends from the
condenser; and although we have shown bobbins without flanges we wish it to be
clearly understood that bobbins with flanges may be employed; and also the series
of small bobbins may be mounted and guided on the drum or drums in any
convenient manner other than that shown.
By the use and application of these improvements we save a considerable amount
of waste and time and largely increase the production of the machine.
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 arrangement use and application of a series of small bobbins or tubes in
substitution for the usual single long bobbin substantially as herein set forth.
2. The general combination and arrangement of parts embodying our improve-
ments in or relating to condensers substantially as herein described with reference
to the accompanying drawing.
