Improvements relating to Drying Cylinders, Rollers, and
Revolving Articles to which Steam or other Vapours or Liquids
are Supplied.
I, SAMUEL MILNE, of 4 Oxford Street, Newington, in the City and County of
Edinburgh, Engineer, do hereby declare the nature of my invention to be as
follows:
This Invention relates to improvements in connections for admitting steam or
other fluid into and letting water out of hollow cylinders, rollers and the like.
The connection is more particularly suitable for the drying cylinders and rolls
used in the manufacture and finishing of paper, but it can be used for any other
purposes where vapours or liquids are admitted into and ejected from any hollow
revolving article.
The object of the invention is to provide in an improved form a connection
having the inlet and outlet on the same connection at same end of cylinder and
to have no loose parts internally, that is, that all parts fitted or placed inside
revolve with the cylinder or roll.
The improved connection is constructed as follows:-
An outer case having inlet and outlet branches and formed to receive the re-
volving stem, packing gland and fittings, and having a chamber round stem to
admit steam from inlet branch to interior of stem. The stem, which is hollow, is
formed with ports or openings to admit the steam to interior. A ring is fixed on
it to retain the packing clear of the ports, and the outer end is formed to receive
the central tube and to bear against the case which is made to suit. The central
tube is fixed to stem at one end, and fixed either to a pan or to roll at other end
as the case may be.
By this means the central tube revolves with cylinder or roll and stem and there
can be no connection between the inlet and outlet branches on casé except through
the central stem.

COMPLETE SPECIFICATION.
Improvements relating to Drying Cylinders, Rollers, and other
Revolving Articles to which Steam or other Vapours or Liquids
are Supplied.
I, SAMUEL MILNE, of 4 Oxford Street, Newington, in the City and County of
Edinburgh, Engineer, do hereby declare the nature of my 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 :-
This Invention relates to improvements in connections for admitting steam or
other fluid into and letting water out of hollow cylinders, rollers and the like.
The connection is more particularly suitable for the drying cylinders and rolls

page_text: used in the manufacture and finishing of paper, but it can be used for any other
purposes where vapours or liquids are admitted into and ejected from any hollow
revolving article.
The object of the invention is to provide in an improved form a connection
having the inlet and outlet on the same connection at same end of cylinder and
to have no loose parts internally, that is, that all parts fitted or placed inside
revolve with the cylinder or roll.
And in order that my said invention and the manner of carrying same into
practice may be properly understood, I have hereunto appended an explanatory
drawing illustrating my improvements.
The improved connection is constructed as follows:-
An outer case A having inlet and outlet branches A' and A³ respectively and
formed to receive the revolving stem 13 packing gland B' and fittings, and having
a chamber B2 round stem B to admit steam from inlet branch A to interior- of
stem B. The stem B which is hollow, is formed with ports or openings 6 to admit
the steam to interior.
A ring is screwed on stem B after gland is on and fixed
with a pin be so as to retain the packing clear of the ports b and the outer end, B
of stem B is formed to receive the central tube C and to bear against à liner A3
in the case A which is made to suit, the part B3 being formed less in diameter
than the main part of stem. B by depth of screw thread. The central tube C is
screwed to stem B at the end B and in the case of cylinders and such like of
large diameter is bent and secured at its inner end, to a pan or scoop secured to
inner surface of cylinder which lifts the water at each revolution of cylinder and
discharges it through the pipe C and outlet A2. The stem B is bolted or fixed
to the part D which is the end of cylinder or roll as the case may be.
By this means the central tube C revolves with cylinder or roll 1) and stem B,
and there can be no connection between the inlet and outlet branches A¹ Aª on
case A except through the central tube C.
In the case of rolls and the like having small bores the central tube C would be
straight and be used as the inlet, and the steam carried by it to the further end
of roll D, the water being discharged through the ports b in the stem, the inner
end of the tube C being secured to a plug or a ring within the roll and perforated
to allow the steam to escape to heat the roll.
Having now particularly described and ascertained the nature of my said n
vention and in what manner the same is to be performed I declare that what I
claim is
First. In combination with drying cylinders, rollers, or other revolving articles,
an apparatus having the inlet and outlet openings on the same connection at same
end of cylinder, and having no loose parts internally, substantially -as- herein
described in reference to and shown in the accompanying drawing.
Second. A connection for drying cylinders, rollers, or other revolving articles,
in which the internal pipe is secured to the revolving stem, so that same revolves
with the cylinder or roll, substantially as herein described in reference to and
shown in the accompanying drawing.
Third. A connection for drying cylinders, rollers, or other revolving articles
in which the stem is formed with ports or openings, so that one connection between
interior of stem and case is made through the body of the stem, and the other
through the end of the stem, substantially as herein described in reference to and
ehown in the accompanying drawing.
