PROVISIONAL SPECIFICATION.
Improvements in Back-washing Machines for Use in the Treatment
of Wool or other Fibrous Substances.
We, JAMES RAMSDEN HOYLE and HEBDEN COLBURN both of the Firm of
Hoyle and Preston of Keighley in the County of York, Machine Makers, do
hereby declare the nature of this invention to be as follows, that is to say :-
It relates to improvements in that class of back-washing machines wherein the
drying-drums are mounted on bearings which are carried or supported by having
one of their respective ends or extremities fixed to the framework of the machine,
and our said invention cousists in so constructing said bearings and drums and
arranging them in such a manner that while ample support is afforded to these
latter, the steam for heating them is brought into direct contact with their
peripheries thus the radiation of the heat therefrom is more effective in its actions
on the wool or other fibres being treated, than has heretofore been the case when
this type of machine has been used.
In accordance with our invention the bearing for the drum is fixed to the
framework of the machine from which it extends laterally into a space made
concentrically within said drum in order that a hollow shaft or sleeve fixed to and
within the drum, may rest thereon to form the drum's support.
This hollow shaft leads into a chamber or cavity formed within the extended
end of the drum so that steam passing through this sleeve and cavity may be
conducted to an annular chamber made in contiguity with the drum's periphery
by which means said periphery alone intervenes between the steam and the wool
or other fibrous substance which said drum carries and which has to be thereby
treated.
To enable the steam to circulate freely within the drum an outlet pipe is fixed
to extend longitudinally within the sleeve and to enter the cavity in the end of
the drum.

Improvements in Back-washing Machines for Use in the Treatment
of Wool or other Fibrous Substances.
We, JAMES RAMSDEN HOYLE and HEBDEN COLBURN both of the Firm of
Hoyle and Preston of Keighley in the County of York, Machine Makers, 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, that is to say :-
It relates to improvements in that class of back-washing machines wherein

page_text: the drying-drums are mounted on bearings which are carried or supported by
having one of their respective ends or extremities fixed to the framework of the
machine and our said invention consists in so constructing said bearings and
drums and arranging them in such a manner that while ample support is afforded
for these latter, the steam for heating them is brought into direct contact with
their peripheries, thus the radiation of the heat therefrom is more effective in
its actions on the wool or other fibres being treated, than bas heretofore been the
case when this type of machine has been used.
In the accompanying sheet of drawings which is iilustrative of our invention :-
Fig. 1 is a side elevation of a sufficient portion of a back-washing machine to
show the application thereto of our invention.
Fig. 2 is a longitudinal section of a drum, its bearings and parts in connection
therewith, constructed and arranged in accordance with our said invention.
In carrying our invention into effect we secure the bearing a for the drum b to
the framework c from which it extends laterally into a space d made concentrically
within said drum b by its inner walls being formed as shown in order that a
hollow shaft or sleeve f fixed to the walls b' and within the space d may rest upon
these bearings a to form the support for said drum b, the centre of gravity of
which is thus arranged to lie or fall nearer the fixed than the extending end of
the said bearing a.
This hollow shaft f leads into a chamber or cavity 9 formed within the extending
end of the drum so that steam entering the sleeve by the pipe h and passing
through same as shown by the arrows k, into the cavity g may thus be brought
into direct contact with the periphery of the drum b by reason of the cavity g
extending into the annular cavity gl around the central or inner walls b', by which
means said periphery alone intervenes between the steam and the wool or other
fibrous substance which said drum b carries on its outer surface during its process
of treatment.
To enable the steam to circulate freely within the drum ban outlet pipe m is
fixed to extend from the stationary plug p through the sleeve f into the space or
cavity g through which any water of condensation etc., may be conducted away by
means of the continuation pipe s.
Rotary motion is imparted to the several drums in the well known manner,
these said drums b being geared together through their respective wheels t as is
well understood.
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. In a back-washing machine, a drum formed and constructed as described
and bearings for supporting said drum in combination substantially as specified.
2. In a back-washing machine, a drum having its internal walls arranged so
that an annular cavity is formed concentrically with the drum's periphery
substantially as herein specified.
3. In a back-washing machine, a drum constructed so that it may be supported
by a sleeve secured to it in such a manner that the centre of gravity of said drum
and sleeve when in position will fall nearer to the fixed end of their bearing or
support than to the extending end of same substantially as specified.
