A New or Improved Pipe Joint.
We, WILLIAM GEORGE EVANS, Engineer, of 3 Frith Road, Leyton Road,
Leytonstone E. and MARTIN EDWARD BROOKE, Engineer, of 81 Westdown Road
Leyton Road, Stratford, Essex, do hereby declare the nature of this invention to
be as follows:-
:―
This invention relates to improvements in pipe couplings and the same is carried
out in the following manner.
I provide two caps or unions. One cap is provided with an external thread, and
the other cap is provided with an internal and corresponding thread. The other
ends of the caps or unions have conical or tapered apertures, through these
apertures the ends of the pipes to be connected pass.
Each of caps or unions is provided with suitable packing such as rubber rings.
Between the packing and over the ends of the pipes a bevelled ring is placed. A
bevelled gland is employed in one of the caps.
When the two caps are screwed upon one another. The packing is tightened
around the pipes on each side of the bevelled ring through the medium of the
gland & caps or unions, aforesaid.
The whole arrangement of the gland, packing & ring is enclosed in the two caps
or unions.
The conical or tapered apertures in the caps or unions allows of a
certain amount of vibration, the larger diameter of the aperture being towards the
outside of the ends of the cap.

COMPLETE SPECIFICATION.
A New or Improved Pipe Joint.
We WILLIAM GEORGE EVANS and MARTIN EDWARD BROOKE 3 Frith Road
Leyton Road Leytonstone, Essex, 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:-
This invention relates to couplings for connecting pipes together & consists in
providing a ready means of coupling or connecting the ends of pipes together and
the same is carried out in the following manner.
Referring to the annexed drawing
Figure 1, is a longitudinal section of my invention in position.
Figure 2, side elevation of same.
a&a are the pipes to be connected, is a cap or union having the external
thread c on same which engages in a corresponding internal thread formed on the
cap d. e is any suitable packing such as rubber rings encircling the pipes a & a³.
is a metal ring which encircles the pipes a & a¹ at their junction ; this ring is
bevelled at as shown. i is a gland having the bevelled end and conical or .
tapered aperture k. The cap has also a tapered or conical aperture 1. It will
be seen that by screwing the cap d upon the cap, the gland i forces the packing e
against the pipe a & a & also against the sides of the ring and sides of the cap b,
thus making a tight joint. The tapering or coning of the apertures k and I allow
of a certain amount of vibration of the pipes a & a'.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combined construction and arrangement of the various parts substantially
as described and shown.
2. A pipe coupling, consisting of two caps or unions having screw threads at one
end and apertures at the other, a gland with or without a bevelled edge, a bevelled
ring, which is placed over the junction of the ends of the pipes to be connected, said
ring having packing or rubber rings on each side of same and encircling the pipe to
be connected, substantially as described and illustrated.
