WALTER PORTER, of Stratford House, Tyndall's Park Road, Bristol, House
Agent, and EDWARD COLSTON JOSEPH, of Portsea Lodge, Chestfield Road.
Bristol, House Agent, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to a new or improved appliance for connecting water,
steam, gas, and other pipes, also bars, rods, cables, and similar articles, thereby
dispensing with the soldering or tapping which is at present employed in making
pipe and rod fastenings.
Our invention consists in making a tubular covering or socket, which is screw-
threaded, and a suitable number of tapered slots cut near the ends, which will
permit the extremities to be compressed by running sockets or tapered nuts which
are worked over the ends when the pieces of pipe or material to be united have
been inserted a central boss with square or angular sides is made on or fastened
to the outside of the socket, by which it is held tightly by a spanner while the
teper nuts are turned over the slotted ends; the central boss may be in one piece
or made in two parts, one screwing laterally into the other, thus forming a
supporting union; the internal surface of the socket is lined with oft metal (like
lead), leather, rubber, asbestos, or other suitable packing, the interior being
grooved in places to keep the lining firm; the lining may be first inserted in the
socket in one piece, or may be made in two parts, one of which, like a thimble, is
put over the ends of the pipes to be united, and the pipes with the thimbles thercon
are put inside the slotted ends of the socket, and then when the rumming sockets
are tightened over the fixed socket, the lining will be so firmly pressed into the
pipe or other material, that a perfect grip will be formed, and a thoroughly steam
tight joint be made.
The sockets may be made either straight, T, or elbow-shaped, as may be
preferred.

COMPLETE SPECIFICATION.
A New and Improved Grip or Union for Pipes, Bars, Cables, Rods,
and the like.
We, FREDERICK PARLOUR, of 11, Belle Vue, Clifton, Bristol, Plumber,
WALTER PORTER, of Stratford House, Tyndall's Park Road, Bristol, House
Agent, and EDWARD COLSTON JOSEPH, of Portsea Lodge, Chesterfield Road,
Bristol, House Agent, 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 new or improved appliances for connecting water,
steam, gas, and other pipes, also bars, rods, cables and similar articles, thereby
providing a much readier means for attaching these goods than is at present used
for this purpose.

page_text: Our invention consists essentially in making a tubular socket, the ends of which
are split by cutting taper slots in them, so that they become collapsible, and when
the tubes, or other articles, to be united are put in the socket, the slotted ends are
pressed inwards by screwing a taper collar over each end of the socket, which
firmly grips the tubes or other goods put therein.
Our invention will be further described in connection with the accompanying
sheet of drawings, in which
Fig. 1 represents a screw-threaded cylinder, on the outside of which is a central
boss, either made on or fixed to the cylinder;"
Figs. 2 and 3 are collars which are screw threaded on the interior and slightly
tapered to fit over the slotted ends of the cylinder;
Fig. 4 is a vertical section across the central boss, showing a tube in its position
in the socket; and
Fig. 5 is an exterior view of the socket and collars with pipes inserted and
connected.
A is the cylinder, screwthreaded and having a suitable number of taper slots a
cut in the ends, a central boss B is attached to the cylinder, this may be in one
piece as shown, or in two parts, one screwing into the other, thus increasing the
Strength of the grip or union; Care collars or running sockets, shown in position
ready to be placed over the slotted ends of the cylinder, the interior of the sockets
being screwthreaded, and slightly tapering towards the outer ends, so that the
further they are worked on the cylinder, the greater will he the pressure on the
tubes D or other articles to be united. To equalise the pressure on the tube, and
also to form a packing, a thin lining, E, of soft metal, (such as lea1;, leather,
rubber, asbestos, or the like, is placed in the interior of the cylinder, grooves being
formed therein for the purpose of retaining the lining in position: the lining may
be made in one piece, reaching from end to end, or in two pieces, one being placed
over the end of each of the tubes to be joinesi, like a thimble, and then the two
ends with the thimbles on them, inserted in the socket.
The various parts being provided as described, their operation is as follows:
The ends of the tubes or other articles to be joined are brought together, and the
collars placed over them, the ends are then put in the socket and made to meet,
or nearly so, under the central loss, the lining having been either put in the socket
or over the ends of the tubes, the tapered collars Care then worked over the slots,
and by means of spanners, one holding the central boss, and the other turning the
nuts of the collars, the joint is made steam or water tight, and will resist an
enormous amount of pressure.
Instead of the cylinder being made straight, as shown, it may be made T or
elbow shaped, the supporting bosses being put in the necessary positions to
strengthen the cylinder. For repairing water pipes that have burst, the cylinder
and boss and collars are divided longitudinally in two parts, and placed round the
pipe, the collars being re-fastened by hooks and studs, just as locking nuts are
instened, by this means a joint can be made without removing the pipe.
For garden, fire, and other flexible hose, a thin metal tube is attached to the
interior of the socket, projecting beyond its extremities, leaving a circular groove
between the tube and the socket: the hose is put over the tube and pushed into
position, and the collars will press the slotted ends on the hose while the small tube
resists the pressure, and thus forms a perfectly watertight joint.
If preferred, instead of making the collars C with a tapered interior, the
socket A may be tapered towards the ends and the interior of the collars be made
uniform throughout, but the result of using them in this form is not so satisfactory
as when following the method previously described.
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 :-
The provision of a grip or union for pipes, bars, cables, rods, and similar articles,

page_text: to form a reliable joint, consisting essentially of a cylinder made compressible at
the ends by slots cut therein, and tightening the same by tapered screw collars or
similar mechanical means; substantially as and for the purposes herein set forth
and described, and illustrated in the accompanying drawings.
Dated this 19th day of December 1893.
