COMPLETE SPECIFICATION.
Improvements in connection with Cylinders for Drying Textile
Fabrics or the like.
We, JOHN BROAD JACKSON and GEORGE BENTLEY both of Lodge Bank
Works Bury in the County of Lancaster Engineers do hereby declare the nature of
our 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 relates to improvements in connection with cylinders heated by
means of steam for drying textile fabrics or the like and has for its object to
provide means for readily and efficiently removing from the cylinders water of
condensation which collects therein.
According to our invention we cast onto the inner side of the end or ends of the
drying cylinder a metal bucket or buckets or receptacles each bucket being
preferably formed heart shaped or expanded towards the circumference of the
cylinder and contracted towards the axis thereof where it terminates in a pipe or
nozzle opening into a hollow trunnion on which the cylinder revolves. The said
bucket or receptacle is provided with an aperture towards its base or part adjacent
to the periphery of the cylinder through which as the cylinder revolves the water
of condensation enters and is delivered through the central nozzle and hollow
trunnion to the exterior of the cylinder.
The shape of the bucket or receptacle may differ from that we have described
provided it be so formed as to be capable of receiving the water of condensation in
whichever direction the cylinder may revolve.
Instead of casting the bucket in one with the cylinder the said bucket may be
attached by bolts screws or otherwise to the drying cylinder.
When the cylinder is in a position so that the entrance to the bucket is below
the surface of the water of condensation the pressure of steam acting on the water
will force the water from the cylinder through the bucket and trunnion to the
exterior thereof whether the cylinder be rotating or stationary.
In the accompanying drawings we have shewn the means we preferably employ
according to our invention for removing water of condensation from a drying
cylinder. Figure 1 is an end view of a drying cylinder with a bucket attached
thereto and Figure 2 is a side elevation.
Onto the inner side a of the end of the drying cylinder A we cast a bucket B
preferably of the shape shewn in the drawing being expanded at 6 towards the
circumference of the cylinder and contracted towards the axis thereof and
terminating in a pipe or nozzle b opening into the hollow trunnion C on which the
cylinder A revolves. The bucket is provided with an aperture 6 through which
the water of condensation enters. D is a balance weight secured to the cylinder A
for counteracting the weight of the bucket B.
When the cylinder A revolves, the water of condensation enters the bucket B
at the aperture 6 and is delivered through the nozzle b and hollow trunnion C to
the exterior of the cylinder. When the aperture 2 is below the surface of the
water of condensation the pressure of steam acting on the water will force it
through the bucket B to the exterior of the cylinder whether the cylinder be
rotating or stationary.
Figures 3 and 4 shew a modification in which the bucket B is secured to the
inner side a of the end of the cylinder A by means of bolts 63 passing through
flange pieces cast on the bucket and screwing into the said cylinder end. By this
means a bucket may be readily removed if required and replaced.

page_text: 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 drying cylinder for textile fabrics or the like a bucket or buckets formed
on or secured to the inner end or ends of the said cylinders and provided with a
feed aperture and communicating with a delivery nozzle all being constructed or
arranged substantially as herein before described.
2. In combination with steam heated drying cylinders a bucket formed as
described and cast on the cylinder end substantially as hereinbefore described and
shewn in Figures 1 and 2 of the accompanying drawings.
3. In combination with steam heated drying cylinders a bucket formed as
described and bolted screwed or otherwise fastened to the cylinder end substantially
as hereinbefore described and shewn in Figures 3 and 4 of the accompanying
drawings.
Dated this 13th day of November 1894.
