page_text: We, JOHN ELLÁM, of the Vicarage, Herne Bay, Clerk in Holy Orders, and
EDWARD THOMAS JOHN ADAMS, of Herne Bay, Builder & Surveyor, both in the
County of Kent, do hereby declare the nature of our invention to be as follows:-
Our invention relates to an improved method of jointing iron pipes, more
particularly those that are used as gas and. water-mains.
We retain the well known socket end, forming its inner face, against which the
spigot end is pressed, of sufficient area to produce a seat for a washer.
We form a collar of, preferably, the same external diameter as the socket, on the
spigot end of the pipe but, at a distance from said end about equal to the
internal length of the socket, as well as one or more projections upon the face of
this collar, which take into corresponding notches in the face of the socket.
A pair of lugs is also formed upon each socket and collar, by means of which the
two pipes can be drawn together by bolts after the washer has been inserted. We
form an extension upon the front faces of two lugs to prevent the act of screwing
up being continued after the joint is made.

page_text: We, JOHN ELLAM, of the Vicarage, Herne Bay, Clerk in Holy Orders, and
EDWARD THOMAS, JOHN ADAMS, of Herne Bay, Builder and Surveyor, both in the
County of Kent, 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 an improved method of jointing iron pipes, more
particularly those that are used as gas and water mains.
In order that it as well as the means by which it can be put into practical
operation may be thoroughly understood, we will proceed to describe the same in
detail referring in so doing to the accompanying figures which are to be taken as
part of this specification and read therewith, and in which like parts are marked
with the same reference letter.
Fig. 1 is a longitudinal elevation partly in section illustrating our invention.
Fig. 2 is an end elevation one half being in section.
A is the socket, B the spigot end, and C a face formed inside the socket and
furnishing a seat for a washer D.
The washer may be of any suitable and convenient material.
E is a collar formed upon the spigot end of the pipe at a distance from its end
about the same as the internal length of the socket.
If desired, projections can be formed upon the face of the collar, to take into
corresponding notches in the face of the socket end to facilitate the correct
approximating of the adjacent ends of two pipes.
Fis a second washer.
The faces of the seating of this second washer are plane surfaces, but we prefer
to make the seating of the washer D and the face of the spigot end with projecting
rings of a conical transverse section, between which the washer is wedged, and the
joint made tighter against severe internal pressure.
G, G, are lugs in pairs by which the pipes can be coupled.
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 combination of socket end, internal washer seating, spigot end, collar and
lugs, substantially as described with reference to the accompanying figures.
