I, RICHARD PAUL FISHER, of Claughton Villa, Brincliffe Edge, Sheffield, in the
County of York, Commercial Traveller, do hereby declare the nature of my said
invention for "IMPROVEMENTS IN PIPE JOINTS," to be as follows:—
This invention relates to an improved joint for connecting water, gas, and other
pipes of a like nature and consists of a short tube cut longitudinally through the
centre having projections two on each side the tube, which when the parts are brought
together take the form of a wedge.
When it is desired to form a joint the two parts are placed round the pipe, and two
keys having a wedge shaped groove are slid along the projections, one on either side,
from the narrow ends thereof until the said parts are forced tightly together.
To prevent an escape from the joint the said parts will be lined with india rubber,
asbestos, or other suitable yielding material.
The joint as above described will be made of cast iron, or other suitable metal and
to any required size.

page_text: I, RICHARD PAUL FISHER, of Claughton Villa, Brincliffe Edge, Sheffield in the
County of York, Commercial Traveller, do hereby declare the nature of my said
invention for "IMPROVEMENTS IN PIPE JOINTS" 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 an improved joint for connecting water, gas, and other
pipes of a like nature and consists of a small tube cast in two or more parts each part
being furnished with two or more projections, which when the said parts are brought
together assume the form of a wedge. These wedge shaped projections are formed
with the taper ends diagonally opposite to each other, and to make the joint secure
two or more keys having wedge shaped grooves are slid or forced along the projections
from the narrow end thereof until the two or more parts are brought tightly together;
the taper ends of the said projections being diagonally opposite as before stated
constitute a lock.
Before coupling the pipes with the joint the two ends are placed into a broad or
narrow india-rubber ring, or by preference are wrapped round with canvas or other
suitable material for the purpose of preventing the packing which fills the remaining
portion from getting into or between the ends of the pipes. The said joint may be
packed with either india-rubber asbestos, red and white lead with spun yarn, or other
suitable material but by preference with red and white lead with spun yarn.
Or, one half or portion of the said joint may be cast to one end of the pipe so that
the other part or portion will only have to be placed over the pipe and wedged as
before described.
As a modification this joint may be utilised for coupling a broken shaft exactly in
the same way as for coupling pipes.
This joint may be either plain inside or corrugated for the purpose of giving bond
and holding the packing securely in position and is of great value in case of
an escape.
I will now proceed to explain the details of the construction and application of this
invention, reference to the different figures illustrated in the accompanying drawings
being made by the several letters thereon represented.
Fig. 1, is a front elevation shewing the ends of two pipes A and B and one half of
the corrugated joint C each half being grooved at I, also the india-rubber ring or
canvas D, and the packing E.
Fig. 2, is a front elevation shewing the coupling of a broken pipe or shafting and
the section of two round india-rubber rings, F, F.
Fig. 3, is a plan shewing the joint coupling two pipes A, B, whereon is the
wedge shaped projections Gover which is the wedge-key H securely closing the
said joint.

page_text: Figs. 4 and 5 are plans shewing the joint as applied to different bends or T pieces
others of which are to numerous to illustrate.
Fig. 6, is a front elevation of the wedge key H.
Fig. 7, is a plan shewing the underside of the wedge-shaped groove corresponding
with the wedge shaped projection on the joint.
Fig. 8, is a plan of fig. 6.
Fig. 9, is an end elevation of fig. 6.
Fig. 10, is an end elevation of the joint C, shewing the wedge key H on the
projection G also section of the pipe B.
Fig. 11, is a section in elevation shewing the joint as divided into four pieces.
The materials used and the general details of the construction of this invention are
the same as are usually employed in the manufacture of the pipes to which it will be
attached and may be made to any required shape or size.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
Improvements in joints for coupling or connecting the ends of water, gas, or
other pipes also for repairing same including broken shafting by making the said
joints in two or more parts having thereon wedge-shaped projections, and which
said joints are fastened tightly over the said pipe ends by means of two or more
wedge keys being slid or forced along the said wedge-shaped projections sub-
stantially as herein before, specified, described and as illustrated by the accompanying
drawings.
