I WILLIAM RICHARDSON of Saint Johns Street Mansfield in the County of
Nottingham Managing Director of the "Meadow Foundry Company Limited
Mansfield do hereby declare the nature of my Invention for IMPROVEMENTS IN
JOINTS OR COUPLINGS FOR PIPES 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 a new system of joint or coupling or mode of making
the joints in pipes or tubes of cast iron or other material and their connections
for hot or cold water, steam, rain water conductors, soil ventilating shafts, sewers
and other purposes where perfectly tight and sound joints are required with india
rubber or other suitable material. The object being to provide a simple and
ready method of connecting or securing together tightly and soundly the ends of
pipes, tubes or their connections and which shall admit of the connected pipes,
tubes or connections being set in any position by allowing the complete rotation
on its own axis of each pipe tube or connection.
To carry out this Invention reference being had to the accompanying Drawings
I cast or fit on and near the male or spigot end of and extending wholly around
the pipe tube or connection a collar or projection "A" Figures 1 and 2 of two
different diameters or where more suited to the requirements I form the joint face
of the shape shewn at "L" in half section Figure 10 or of the shape shewn
at "K" in half section Figure 11 (or I provide a loose ring and collar clip or
flange to form such collar or projection as hereinafter described) such collar or
projection "A" I make either approximately square with the axis of the pipe
tube or connection similar to the shape sliown in Figure 1. or I make it recessed
or hollowed at the back or reverse side to the joint face similar to what is shown
in Figure 2 and which it is obvious may be of any other shape in the said recess
or hollow, or there may be a projection wholly around the reverse side to the joint
face of such collar or projection which may be of a variety of shapes in such
projection the object being to form a grip to the securing bolt and nut when the
slotted tabs or lugs "D" Figures 2 and 4 are used and so prevent the same-slipping
away from its position.
The female or faucet end "B" Figures 1. 2. 8. is made large enough internally
to receive a portion of the said collar or projection "A" on the male or spigot end
Ls shown in sections 1: 2; and 8 together with the packing "J" of india rubber or

other suitable material and may be of the same diameter internally for the whole
of its length or I make it of two or more different diameters in its length internally
after the manner shown in Figures 1. 2. and 8 to correspond with the said
collar "A" or as previously described after the manner shown in Figures.10, and 11.
On the outside of the said faucet "B" I cast two or more lugs or tabs "C"
Figures 1 and 3 with holes of sufficient size to receive the bolts as shown and
which keep the bolt heads securely in position against the square back of the
collar "A"
or I cast two or more slotted lugs or tabs "D" Figures 2 and 4 on the
outside of the faucet as shown; the bolt passing through the said slot and being
securely held in position by the recess or projection at the back of the collar "A
Figure 2 as before described. To secure the two joining ends of pipes tubes or
connections Figures 1 and 3 together I employ either an ordinary bolt and nut "E"
as shown flat under the head of the bolt or a special made bolt of any shape on the
outside of the head may be used for example those shown in Figures 5. 6. and 7 but
I do not confine myself to these. And to secure the two joining ends of pipes tubes
or connections Figures 2 and 4 together I use a special made bolt and nut "F" of
the shape shown or any other similar shape capable of acting in a similar manner
in conjunction with the recessed hollowed or other shaped back part of the collar
or projection "A" Figure 2 forming the grip to the bolt as before described.
Where more convenient a separate flange ring or clip may be used to fit behind the
said collar or projection "A" Figures 1 and 2 so as to bear up against the said
collar or projection; the pipes tubes or connections being drawn together by the
bolts and nuts passing through the holes or slots in the said flange ring or clip and
through the corresponding holes or slots in the lugs or tabs "C" and "D" Figures 1
and 2 and screwed up.
For securing rain water pipes, soil pipes or ventilating shafts or for other similar
uses to buildings lugs or ears may be cast on the pipes or independent lugs or ears
may be secured to the pipes tubes or connections by the bolts and nuts. used for
making the joint, passing through the same as shewn in position at "M" Figure 10
and which may be cast on or attached to either the collar on male end as shown or
the socket on female end of the pipe tube or connection.
.In order to use up waste pieces of pipes or pieces that may have been cut off
longer lengths and having the ends quite plain I use a loose collar, clip or
flange "G" Figures 8 and 9 having the internal diameter larger at the front or
portion nearest the joint face than at the back part and slightly larger at such back
part than the external diameter of the pipe tube or connection. Such collar clip or
flange "G" as regards the back or reverse side to the joint face may be either as
shown in the collar or projection "A" Figures 1 or 2 or it may have lugs or tabs
with bolt holes or slots in same to correspond with the holes or slots in the lugs or
tabs "C" and "D" Figures 1 and 2. I also use a metallic ring "H" wedge
shaped in section about the same diameter internally as the external-diameter-of-
-the pipe tube or connection and externally for part of its length of similar diameter
and shape to the internal diameter of the collar clip or flange "G" terininating of
the same diameter and is for the same purpose as regards the making of the joint
as the front or joint face portion of the collar or projection "A" Figures 1 and 2 or
as shown at "L" Figure 10 or at "K" Figure 11 namely to force the india
rubber or other packing against the seating or seatings in the faucet "B." The
said metalic ring being divided or cut through one side only, so as to impart
elasticity to the same and for the purpose of increasing. its elasticity it may be
further divided partially in several places after the manner shown by the dotted
lines "O" Figure 8 or in any other similar manner having the same object.
By the use of this metalic wedge shaped ring in conjunction with the loose collar
clip or flange "G" as the two pipe tube or connection ends are drawn together
there is a corresponding latteral pressure on the pipe tube or connection by the
loose collar clip or flange "G" being drawn on the wedge shaped metalic ring "H"
the end of the waste or cut pipe being thereby firmly and permanently held in
position.

page_text: 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
1. The employment of the collar or projection "A" Figures 1. 2. 10 & 11 or
other similar shape as described whether cast or fitted on the pipe tube or
connection and the peculiar and special character of the bolts employed and also in
conjunction with the lugs or tabs "C" and "D" and the loose collar clip or
flange to bear against the collar or projection "A" as described by which each of
the joining pipes tubes or connections may be secured in any position on its own
axis substantially as set forth.
2. The employment of the loose collar clip or flange "G" and the wedge shaped
metalic ring "H" substantially as and for the purpose set forth.
