PROVISIONAL SPECIFICATION.
An Improved Method of Forming the Joints of Pipes for Steam,
Water, and other Fluids.
1, JAMES GEORGE STIDDER, of 66 Waddon Old Road, Croydon, in the
County of Surrey, Sanitary Engineer, do hereby declare the nature of my said
invention to be as follows:-
The object of my invention is to supplement the ordinary screw sockets and
analogous devices as applied to pipe joints, with an elastic packing ring, and screw
collar, for the purpose of rendering the same fluid tight under all pressures.
In carrying out my invention, I form annular recesses in the ends of the sockets,
or equivalent coupling devices, in which recesses I fit rings of copper, lead,
asbestos, rubber, cord, or other suitable material, with or without the addition. of
red lead and the like, as required. I also fit the pipes with corresponding screw
rings or back nuts, having annular projections suitable for entering the recesses in
the sockets, and compressing the elastic material.
When the screw rings and sockets or coupling devices have been placed upon
the ends of the pipes to form a joint, the elastic packing is inserted in the ends of
the sockets. The rings or back nuts are then screwed up to the sockets so as to
compress the packing, until the joint is rendered perfectly fluid tight.

COMPLETE SPECIFICATION.
An Improved Method of Forming the Joints of Pipes for Steam,
Water, and other Fluids.
I, JAMES GEORGE STIDDER, of 66 Waddon Old Road, Croydon, in the
County of Surrey, Sanitary Engineer, do hereby declare the nature of my said
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 my invention is to supplement the ordinary screw sockets and
analogous devices as applied to pipe joints, with an elastic packing ring, and screw
collar, for the purpose of rendering the same fluid-tight under all pressures.
In carrying out my invention, I form annular recesses in the ends of the sockets,
or equivalent coupling devices, in which recesses I fit rings of copper, lead, asbestos,
rubber, cord, or other suitable material, with or without the addition of red lead
and the like as required. I also fit the pipes with corresponding screw collars or
back nuts, having annular projections suitable for entering the recesses in the
sockets, and compressing the elastic material.
When the screw collars and sockets or coupling devices have been placed upon
the ends of the pipes to form a joint, the elastic packing is inserted in the ends of
the sockets. The collars or back nuts are then screwed up to the sockets so as to
compress the packing, until the joint is rendered perfectly fluid tight.

page_text: And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is an elevation and Fig. 2 a sectional elevation of my improved joint.
Figs. 3 and 4 are end views of the socket and screw collars or back nuts,
respectively.
a is one end of a socket or equivalent coupling device, into which the pipe or
barrel is screwed. An annular recess c is formed in the end of the socket in
which recess I fit a ring of asbestos, copper, lead, rubber, cord, or other suitable
material with or without the addition of red lead and the like, as required. The
pipe or barrel b is fitted with a screw collar or back nut e formed with an annular
projection suitably shaped for entering the recess c in the socket a and compressing
the packing d, the back nut e being screwed up until the joint is rendered perfectly
fluid tight.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
The improved method of forming the joints of pipes for steam, water and other
fluids, substantially as herein before described and illustrated by the drawings.
