Improvements in or relating to Drying Cylinders,
JACOB BRIDGE, Ironfounder, Machinist, Tinplate Worker and Coppersmith,
Paradise Works, Accrington, do hereby declare the nature of this invention to
be as follows;-
In the construction of what are called cavity drying cylinders used in the drying
of yarns or woven fabrics it is necessary to connect the space or cavity by means
of tubes or pipes to the centre shaft on which the cylinder is carried, in order to
feed such cavity with steam and also for the purpose of carrying off the water
caused by condensation. These pipes are called respectively the inlet and outlet
pipes. Hitherto they have been made of ordinary metal piping preferably bent to
allow for expansion and contraction of cylinder, but as in practice the couplings
or connections where these are joined to cylinder body and centre shaft are a
constant source of trouble through leakage caused by expansion and contraction
when steam is turned on or off.
I propose to remedy this by applying the flexible metal tubing now used for
many other purposes in the place of ordinary straight or bent pipes.
The present arrangement of couplings or connections at each end of pipes may be
used the same as used at present for the ordinary piping or may be of any other
kind, my invention relating merely to the application of the flexible tube in place
of the rigid or ordinary tube.

Improvements in or relating to Drying Cylinders.
JACOB BRIDGE, Ironfounder, Machinist, Tinplate Worker, and Coppersmith,
Paradise Works, Accrington, 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; -
In the construction of what are termed cavity cylinders used in the drying of yarns
or woven fabrics, it is found necessary for the purpose of conveying the steam from
the centre shaft to the cavity portion (the surface of which the yarns or fabrics
come in contact with) to use solid metal tubes of a more or less cranked shape
to allow of expansion and contraction and in like manner such tubes are used
for the purpose of carrying away the water caused by condensation from the
cavity portion to the centre shaft. The aforesaid inlet and outlet pipes as they

page_text: are termed are secured to the cavity portion by means of metal connections,
and the whole being of so rigid a character are a constant source of trouble by
causing leakages at the connections, owing to the inability of the materials to
adapt themselves to the expansion and contraction which takes place in the
working of these cylinders.
+
I purpose to remedy these defects by making the said inlet and outlet pipes
of flexible metallic tubing wholly or in part as may be thought necessary, and in
order that my invention may be properly understood and readily carried into effect,
I will proceed to describe the same by the aid of the accompanying drawing which
shews the aforesaid inlet and outlet pipes to be made with only a part of the
flexible tubing.
A is the inside body of cavity cylinder.
B is the centre shaft.
C are the solid metal tubes or pipes.
1) are the metal unions or connections.
E.is the flexible metal tube which is screwed and soldered in the metal elbows F.
Also variations in detail may be made without departing from the peculiar
character of my invention such as in the shape of the pipes or tubes, and where
only a portion of the flexible metal tube be used, it need not necessarily bear
the same relationship to the centre shaft & cavity portion as shown on drawing.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
Pipes or tubes made of flexible metal wholly or in part for conveying the steam
and water from and to centre shaft to the cavity as described and shewn.
