Improvements in or relating to Cylinder Drying Machines for
Textile Fabrics and Paper.
We, THOMAS LEVER of 37 Grant Street, Tin Plate Worker, and WILLIAM
HENRY LIPTROTT of 3 Platt Street, Clerk, both of Bolton in the County of
Lancaster, do hereby declare the nature of our said invention to be as follows:-
This invention refers to improvements in or relating to cylinder drying machines,
better known as drying tins or revolving cylinders, heated by steam for drying
textile fabrics and paper, and consists in means for preventing the formation of
coagulated matter or substance, and conveying condensed and other water
therefrom. This we effect by fixing double or other angular buckets therein
provided at each end with spouts connected to a tapered or other hollow centre
with a bell-mouthed or other end and a pipe; the latter fitting into a passage
through the supporting shaft or centre, from whence water is conveyed away in any
convenient manner. The double angular buckets are so disposed that, as the said
tin or cylinder rotates, the condensed or other water that collects therein will be
scooped up and delivered to the tapered or other hollow centre. The spouts in the
buckets are constructed to prevent the water collected flowing back as the tin or
cylinder rotates. In case the drying tin or cylinder is of unusual or other length
it may be strengthened by means of one or more T iron or angle rings secured in
any convenient manner. To enable the water that collects between the said
strengthening rings being passed to the outlet other buckets are employed for
conveying the same to the outlet end of the tin or cylinder.

We THOMAS LEVER of 37 Grant Street, Tin Plate Worker, and WILLIAM

Lancaster, 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 and accompanying drawings
This invention refers to improvements in or relating to cylinder drying machines,
better known as drying tins or revolving cylinders, heated by steam for drying
textile fabrics and paper, and consists in means for preventing the formation of
coagulated matter or substance, and for conveying condensed and other water
therefrom. This we effect by fixing double or other angular buckets therein
provided at each end with spouts connected to a tapered or other hollow centre
with a bell mouthed or other end and a pipe; the latter fitting into a passage
through the supporting shaft or centre, from whence water is conveyed away in any

The
The double angular buckets are so disposed that as the said
tin or other cylinder rotates, the condensed or other water that collects therein
will be scooped up and delivered to the tapered or other hollow centre.
spouts in the buckets are constructed in such a manner as to prevent the collected
water from flowing back as the tin or other cylinder rotates.
To render our invention clearly understood we will now refer particularly to the
annexed drawings in which Fig. 1 represents one end of a drying cylinder A in
vertical section, our improved draining buckets a being shown in position. The
upper bucket and the central receiver are shown in vertical section; the lower
bucket is in side elevation.
In cross section our improved bucket a does not vary materially in shape from
the well known tapered buckets ordinarily used for this purpose, but for the sake
of greater clearness we show a section of the bucket a in Fig. 2, the section being
taken at the line B C Fig. 1. The bucket is composed of a mid feather b
extending from one closed end 6 of the bucket to the other closed end b². The
upper edge of the mid feather is soldered to the interior of the cylinder. The
semi-circular or curved bottom c extends upward for a certain distance only,
leaving an opening through which water and other matters enter the bucket as
the cylinder revolves. The mid feather b prevents the water from dashing out at
the other side of the bucket. The curved bottom c presents longitudinally a double
incline shape the apex c¹ being about the centre of the length of the bucket. Thus
each incline presents a watershed leading to a spout e at each end of the bucket,
the said spouts carrying the water down into the central tapered water chamber f.
The spouts e project a sufficient distance into the chamber to obviate the
possibility of the water getting into the spouts from the chamber when the bucket
is in its lower position. A mouth piece fl on the larger end of the chamber f
projects into the hollow bearing of the drying cylinder and takes away the water
poured into the chamber. As the cylinder A revolves the water is scooped into
the buckets and flows through the spouts e into the central chamber and thence
away through the hollow bearing. With the ample delivery space provided by
the double incline buckets spouts e and central collecting chamber the water is
allowed to get freely away in an almost continuous stream. In addition to water,
"
grease and other foreign matters are picked up and removed by the buckets.
When the drying cylinder is of such a length as to require strengthening, rings
of "tee or angle iron, the vertical webs thereof may be perforated to allow
passage of water towards the ends, or we may employ auxiliary buckets to pass the
water forward to the delivery end of the cylinder A.
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 :-
In a drying cylinder the double incline buckets a with a delivery spout at each
end in combination with the central water collecting chamber discharging through
the hollow bearing of the drying cylinder substantially as described and as
illustrated.
