PROVISIONAL SPECIFICATION.
Improvements in Disconnectible Joints and Couplings for Pipes and
the like.
We, ROBERT MARK and WILLIAM MARK, Contractors, 8, Longtown Road,
Brampton, Cumberland, do hereby declare the nature of this invention to be as
follows:
Our invention relates to improvements in disconnectible joints and couplings
for pipes and the like, and in carrying it into effect we proceed in or in about
the following manner :-
We provide near each end of the pipe equi-distantly placed projections some-
what sloped on each longitudinal side and each having its inner end bevelled off
in each direction like a flat "vee" the apex being away from its respective end
of the pipe. For the connecting together of pipes thus prepared we provide a
socket piece having longitudinal grooves at each end of its interior to receive
the projections on the pipe ends. Each set of these grooves open into a cir-
cumferential groove, two of such circumferential grooves being provided inside
the socket for the purpose. Each of the projections thus naturally formed inside
the socket is sloped off on its inner side, and pins or other arrangements are pro-
vided in connection with the socket to enable it to be easily rotated. In use the
projections on the pipe ends are entered into the longitudinal grooves of the socket
and the socket given a partial rotation so as to move the grooves out of coincidence
with the grooves in the sockets, the circumferential grooves allowing the pro-
jections on the pipe ends to pass, and the slopes causing the projections to be
wedged inwards towards the centre of the socket. A resilient or other washer
or packing may be inserted between the ends of the pipes inside the socket and
wedges may be driven into the grooves of the socket so that the upper sides of
the wedges are in contact with the tops of the grooves and the under sides with
the outside of the pipe.

provide near each end of the pipe
We
a equi-distantly placed projections b somewhat
sloped on each longitudinal side c and each having its inner end bevelled off
in each direction like a flat letter V as shown at d, the apex being away from
its respective end of the pipe. For the connecting together of pipes thus pre-
pared, we provide a socket piece e having longitudinal grooves fat each end of
its interior to receive the projections on the pipe ends. Each of these grooves f
opens into a circumferential groove g, two of such circumferential grooves being
provided inside of the socket. Each of the projections h thus naturally formed
inside the socket is sloped off on its inner side and pins or other arrangements
are provided in connection with the socket to enable it to be easily rotated.
In use the projections b on the pipe are entered into longitudinal grooves f of
the socket e, which is then given a partial rotation so as to move the projections b
out of coincidence with the grooves f, the circumferential grooves g allowing the
projections 6 to pass, and the sloping sides d and i causing the pipe to move
inwards towards the centre of the socket e. A resilient or other washer or
packing may be inserted between the ends of the pipes and wedges may be
driven into the grooves f so as to still further tighten up the joint.
The invention is applicable to shafts as well as pipes.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what
we claim is:
1. Disconnectible joints and couplings for pipes and the likes, the said joints
or couplings being provided for by (a) a socket having circumferential grooves
round its interior and longitudinal grooves opening thereinto from the ends of
the socket, the projections thus naturally formed between the longitudinal grooves
having their inner sides sloped; (b) pipe or other ends furnished with equi-
distantly placed exterior projections, destined to enter the above mentioned
longitudinal grooves and to remain in the said circumferential grooves, the sloping
parts of the projections on the pipes or like and those of the parts between the
longitudinal grooves causing the wedging of the pipe or other end towards the
centre of the length of the said socket, (c) a resilient or other washer or packing 3
between the pipe or other ends and (d) wedges to enter the said longitudinal
grooves, the whole substantially as described in the above specification and
exemplified in the accompanying drawing.
2. Disconnectible joints and couplings for pipes and the like, provided for
by a circumferentially and longitudinally internally grooved socket portion into 4
which fit projections provided on the exterior of the said pipe or the like, the
said pipes or the like being retained within the socket by a partial rotation of
the socket, further tightness being obtained by a resilient or other washer or pack-
ing between the ends of the pipes or the like and by wedges driven into the said
longitudinal grooves, the whole substantially as described in the above specifica- 4
tion and exemplified in the accompanying drawings.
3. Disconnectible joints and couplings for pipes and the like provided for and
operating substantially as described in the above specification and exemplified
in the accompanying drawings.
