IMPROVEMENT IN SANITARY AND OTHER PIPE JOINTS
Year: 1885

page_text: GUY HARRY THYNNE Land Agent 11 Great George Street Westminster do
hereby declare the nature of my invention for IMPROVEMENT IN SANITARY AND
OTHER PIPE JOINTS to be as follows:-
Whereby air & water tight joints can be made without the aid of skilled labor
or cement of any kind The socket of the pipe has a groove formed all round its
inner side shewn by E on the elevations & sections The other end of the pipe is
shaped as a truncated cone D with two projecting beaded shoulders or pins C,
A stout band of india rubber or other material B is fitted over the truncated
cone D
To make the joint the truncated cone end of one pipe is passed into the
socket of the next pipe the beaded pins being passed through the two notches F
in the socket till they reach the groove E on its inner side when a slight turn of
the pipe will lock the two together & press the collar of india rubber or other
material B tightly against the sides of the socket forming an air & water tight
joint.

Improvement in Sanitary and other Pipe Joints.
GUY HARRY THYNNE 11 Great George Street Westminster Land Agent do
hereby declare the nature of my invention for IMPROVEMENT IN SANITARY AND
OTHER PIPE JOINTS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of this Invention is to construct the ends of metal earthenware and
other pipes so that they may be locked together at the joints by placing the end

page_text: of one pipe within the socket of the adjoining one and then by giving a turn or
screw separation is prevented unless desired and the joint by the use of india
rubber or other material is effectually sealed against the leakage of fluids, soil or
gas and also when ordinary stopping is used to prevent the pipes being drawn
asunder.
The collar or socket A. A see figure 1 & 2 of the pipe is made with a front
rim F F and a grooved and curved inner side E to E¹. The shape and thickness
of the collar or socket being necessarily modified to suit the material it is made of.
In the front rim F F two or more notches or openings are made to admit the
splayed or bevilled pins fins shoulders or lugs C. Ċ on the other end of the pipes
being passed through them into the collar or socket.
The other end referred to sometimes called the "spigot end" of the pipe is
formed either as a truncated cone or continuously parallel as D D fig. 1. 3 and
upon this there are formed two or more rounded splayed or bevilled pins fins
shoulders or lugs C. C connected together by a band or fillet C¹ fig. 3 formed in the
material of the pipe.
The locking of the joint is effected by the rounded, splayed or bevilled pins fins
shoulders or lugs being passed through the notches or openings in the front rim of
the collar or socket and then turned or screwed as inclined planes and they in
conjunction with the band or fillet push or force the india rubber washer or
gasket or other material B figure 1. 3 against the interior of the collar or socket
of the pipes thus forming a sealed joint preventing the leakage of fluids Boil
or gas.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I claim:
1st The method of rendering the joints of metal earthenware and other pipes
impervious to the leakage of fluids, soil or gas by locking the pipes together when
made as already specified and described by me by inserting the end of one pipe
into the collar or socket of another pipe and then turning or screwing them
thereby preventing one being withdrawn from the other and compressing the
india rubber or other material within the collar or socket thus forming a sealed
joint.
2nd I also claim the method of locking metal earthenware and other pipes
together for the purpose of preventing their being drawn asunder as specified and
described by me but omitting the india rubber or other material when not desired
to make it absolutely impervious to leakage of fluids, soil, or gas.
