Complete Specification Accepted, 23rd Mar, 1889
We, HARRY SKELTON, of 50, Lower Kennington Lane, London, in the County of
Middlesex, Engineer, and BENJAMIN SUTCLIFFE, of Clifton, Brighouse, in the
County of York, India Rubber Merchant, do hereby declare the nature of this
invention to be as follows:-
The object of our invention is to provide an improved joint for connecting parts
through which steam or fluid under pressure is required to pass, while such parts are
able to move in relation to each other.
For this purpose we employ packing of the form described in the specification of
Letters Patent No. 1547 dated 1st February 1887, granted to Thomas Grimshaw
and the above named Harry Skelton, in which the efficiency of the joint is ensured by
causing the pressure of the fluid to act upon the outer surface of such packing.
In carrying out the present invention we form one of the parts through which the
fluid is required to pass with a circular flange or collar beyond which a circular
elongation or nose extends. The other part through which the fluid is required to
pass is provided with a flange at its upper end, and such upper end has a bore or
socket larger than the elongation of the first part, such bore extending down for a
distance somewhat less than the length of the elongation above referred to, when it
becomes narrower so that the elongation will engage and practically fit the reduced
bore when it is inserted therein.
The packing of the form described in the specification of the Patent above referred
to, is inserted in the enlarged bore of the second part; its flange resting upon the
flange of the socket, and its body extending within the latter, but leaving a certain
space between its outer surface and the inner surface of the socket, so that the fluid
under pressure may enter such space and act upon the outer surface of the packing.
The flange on the part first referred to is of smaller diameter than that of the
flange at the top of the socket which it enters, and between its under surface and the
top of the flange on the packing a thin plate, preferably of brass, is interposed, so
as to prevent the flange on the first part from bearing directly upon such packing.

page_text: A cap or cover is slipped over the top of the flange of the first part, its lower end
being recessed to receive the flange of the socket, and bolts are then passed through
the cap or cover and also through the flange of the socket, and serve to secure the
whole together, but as the bolts do not pass through the flange of the first part, the
two parts are free to turn in relation to each other.
The elongation of the first part may fit the reduced bore of the second part
sufficiently freely to enable the fluid to pass up behind the packing, or a passage may
be formed leading from such reduced bore to the socket, for such purpose.
The bore of the packing is such as to enable the elongation of the first part to pass
through same, and when the fluid pressure is acting upon the outer surface of the
packing it forces its inner surface firmly in contact with the outer surface of the
elongation, and thus prevents the fluid from passing up between the two, while at
the same time the two parts are perfectly free to revolve in relation to each other.
The packing may be of india rubber, gutta percha, or of the material known as
"Woodite," or of any other suitable material, and may vary according to the nature
of the fluid the parts are intended to convey.
The above form of joint will be found of great advantage in the case of presses
provided with hollow pressure plates which are required to move in relation to each
other, and at the same time to receive suitable cooling or heating media; and also
in the case of revolving heating or cooling cylinders; and in fact it may be applied
generally in all cases where two parts are required to move in relation to each other
while steam or fluid is being conveyed from one to the other.

page_text: We, HARRY SKELTON, of 50, Lower Kennington Lane, London, in the County of
Middlesex, Engineer, and BENJAMIN SUTCLIFFE, of Clifton, Brighouse, in the County
of York, India Rubber 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 :-
The object of our invention is to provide an improved joint for connecting parts
through which steam or fluid under pressure is required to pass, while such parts are
able to move in relation to each other.
For this purpose we employ packing of the form described in the specification of
Letters Patent No. 1547 dated 1st February 1887, granted to Thomas Grimshaw
and the above named Harry Skelton, in which the efficiency of the joint is ensured
by causing the pressure of the fluid to act upon the outer surface of such packing.
In the accompanying drawing, Fig. 1 is an elevation, and Fig. 2 a plan view
partly in section, showing the invention applied to a press.
In carrying out the invention we form one of the parts A through which the fluid
is required to pass with a circular flange or collar B beyond which a circular elonga-
tion or nose C extends. The other part D through which the fluid is required to pass
is provided with a flange E at its upper end, and such upper end has a bore or socket E¹
larger than the elongation C of the first part, such bore extending down for a
distance somewhat less than the length of the elongation C, when it preferably
becomes narrower at E³, so that the elongation C will engage and practically fit the
reduced bore when it is inserted therein.
The packing F of the form described in the specification of the Patent above
referred to, is inserted in the enlarged bore E¹ of the second part D, its flange FI
resting upon the flange E of the socket E³, and its body F extending within the
latter, but having a certain space between its outer surface and the inner surface of
the socket E', so that the fluid under pressure may enter such space and act upon
outer surface of the packing.
the
The flange B on the part A is of smaller diameter than that of the flange E at the
top of the socket E', and between its inner surface and the top of the flange F' on
the packing, a thin plate G, preferably of brass, is interposed, so as to prevent the
flange B from bearing directly upon such packing.
A cap or cover H is slipped over the top of the flange B of the part A, its lower
end H being recessed to receive the flange E of the socket E¹, and bolts I are then
passed through the cap or cover H and also through the flange E of the socket E¹,
and serve to secure the whole together, but as the bolts do not pass through the
flange B of the part A, the two parts A and D are free to turn in relation to each
other.
The elongation C of the part A may fit the reduced bore E* of the second part
sufficiently freely to enable the fluid to pass up behind the body F2 of the packing,
or a passage may be formed leading from such reduced bore to the socket E', for such

page_text: The bore of the packing F is such as to enable the elongation C of the part A to
pass through same, and when the fluid pressure is acting upon the outer surface of the
body F' of the packing it forces its inner surface firmly in contact with the outer
surface of the elongation C, and thus prevents the fluid from passing up between the
two, while at the same time the two parts are perfectly free to revolve in relation to
each other.
The packing may be of india rubber, gutta percha, or of the material known as
Woodite," or of any other suitable material, and may vary according to the nature
of the fluid the parts are intended to convey.
The above form of joint will be found of great advantage in the case of presses
provided with hollow pressure plates which are required to move in relation to each
other, and at the same time to receive suitable cooling or heating media, the accom-
panying drawings illustrating the application of the invention to such a press. In
this case three of our improved joints are employed, the one X connected to the tube
or conduit V conducting the cooling or heating medium; a second one Y connected
to the hollow pressure plate W; while pipes or tubes R and S leading respectively
from the flexible joints X and Y, are themselves connected together by the third
flexible joint Z.
A similar arrangement of flexible connections is provided between each plate W
of the press and the conduit V, so that such plates will be free to move in relation to
each other and to the conduit V, while maintaining free communication with such
conduit.
The invention may also be applied in the case of revolving heating or cooling
cylinders; and in fact it may be applied generally in all cases where two parts are
required to move in relation to each other while steam or fluid is being conveyed from
one to the other.
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 :-
The improved flexible joint consisting in a circular flange B formned on one of the
parts to be connected together, and having an elongation C projecting therefrom, and
entering the socket E¹ formed on the other part, such socket terminating in a flange E
of larger diameter than the flange B of the first part, the packing F being inserted
between the two flanges B and E, with its body extending into the socket E¹ so as to
leave a space round such body, the whole in combination with a cap or cover H and
bolts or other suitable means for securing same to the flange E, substantially as
specified.
