PROVISIONAL SPECIFICATION.
Heating Drying Cylinders by Gas in Place of Steam.
JOHN MONKS 22 Lucas Road Chorley Lancashire Calico Printer ROBERT
NEWLAND BUSH 74 Pall Mall Chorley Coal Merchant do hereby declare the
nature of this invention to be as follows:-
--
Invention consists of gas tube or tubes with jets, inside cylinders to heat the
same, where steam was formerly used and is at present in use.
The machine to which our invention is applied consists of a number of cylinders
which are used for drying cloth of all descriptions.

Heating Drying Cylinders by Gas in Place of Steam.
We, JOHN MONKS of 22 Lucas Road Chorley, Lancashire, Calico Printer, and
ROBERT NEWLAND BUSH of 74 Pall Mall, Chorley, Coal Merchant; 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 :-
Our invention relates to improved means of heating the cylinders of machines
used for drying fabrics and the like.
It consists in the employment. of a gas tube or tubes having a number of jets,
such tube or tubes being arranged inside the cylinder in a convenient position
for heating same.
To clearly explain our invention reference is made to the accompanying drawings
in which one manner of carrying same into effect is illustrated.
In these drawings
Fig. 1 is a longitudinal section of a cylinder heated in the manner described
above.
Fig. 2 is an end view of same.
Fig. 3 is a cross section on the line - Fig. 1, and
Fig. 4 is an elevation showing an arrangement of a number of cylinders in a
framework with a fabric running over same.
.
The gas pipe a has connected to it a branch pipe b.which passes into a shell
or cylinder A and forms a part of the axle on which said cylinder is supported.
The pipe is fixed in a bushing c on which can loosely revolve a spider d
which forms the end of the drum or cylinder A. A corresponding spider at
the other end revolves loosely on the bushing c¹ fixed on a shaft b'. This
shaft carries bosses e e, an extension e¹ of which abuts against the bushing c
and encloses the end of the pipe b. The space between the ends of the pipe b
and shaft b forms a gas chamber with which connects pipes if which supply
gas to the pipes 9 9 9 provided with burners or orifices. The ends of the
pipes g may have a Bunsen device for mixing air with the gas. The pipes y
TQ; 7

page_text: are supported by discs h h secured to the bosses ee, such discs being connected
by an inner shell so that the gas burns in a space which is enclosed by the
discs hh the shell i, and cylinder A the heat being thereby confined to a
comparatively small space so that it may act most effectively upon the shell or
cylinder A, which it will be seen revolves freely while the pipes f, g, discs h,
and shell are stationary. Air to support combustion will enter through the
space left between the discs h and cylinder A through which also the products
of combustion will escape. A number of cylinders arranged as above may be
combined in a framework as shown in Fig. 4.
•
With the arrangement above described or a similar arrangement whereby the
cylinders are heated by gas a considerably greater heat than with steam heating
can in practice be obtained, the cylinders require no packing at the bearings as
in steam heated cylinders and consequently they are able to revolve more freely
around their axles, so that the power required to pass the fabric over them is
considerably less.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The improved means of heating drying cylinders by gas substantially as
.described.
2. The general arrangement and combination of parts forming the improved gas
heated drying cylinders substantially as described and illustrated.
