PROVISIONAL SPECIFICATION.
Improvements in or relating to Joints for Earthenware Pipes.
I, MATTHEW YARROW, of 36, Rutland Grove, Bolton, in the County of Lancaster,
Building Surveyor, do hereby declare the nature of my said invention to be as
follows:
This invention consists of improvements in or relating to earthenware pipes pro-
vided with spigots and faucets or sockets and is designed to make a perfectly tight
joint in a quick and ready manner, thereby enabling an earthenware pipe, sewer,
or conduit to be effectively and quickly laid so that the ground or earth may be
filled in or made good in the least possible time. The socket or faucet of the
earthenware pipe is tapered internally to allow of easy access of the spigot of the
connecting pipe, and is provided internally with a concaved or other analogous
recess corresponding with a concaved or similar recess to that on the outer diameter
or face of the spigot or faucet. The spigot or faucet is provided with one or more
indents or grooves on each side of the concaved or other analogous recess to receive
strands of picked oakum and the like to make a tight joint and to prevent the
escape of cement when poured into the aforesaidi recesses to joint or connect the
earthenware pipes together. The upper side of the socket is provided with a suit-
able inlet to allow of cement being poured into the recess and a slot to allow of
the escape of air displaced by the admission of cement. To give a firm footing
to the pipe the underside of the socket is provided with a flat bearing surface
moulded on or formed with the same in any convenient manner.
Dated the 15th day of December 1897.

earthenware pipe is tapered internally to allow of easy access of the spigot of the
connecting pipe, and is provided internally with a concaved or other analogous
recess corresponding with a concaved or similar recess to that on the outer diameter
or face of the spigot or faucet. The spigot or faucet is provided with one or more
indents or grooves on each side of the concaved or other analogous recess to receive
strands of picked oakum and the like to make a tight joint and to prevent the
escape of cement when poured into the aforesaid recesses to joint or connect the
earthenware pipes together. The upper side of the socket is provided with a suit-
able inlet to allow of cement being poured into the recess and a slot to allow of
the escape of air displaced by the admission of cement. To give a firm footing
to the pipe the underside of the socket is provided with a flat bearing surface

DESCRIPTION OF DRAWINGS.
Fig. 1 is a sectional longitudinal elevation of earthenware pipes showing my
improved joints sealed and unsealed. Fig. 2 a longitudinal plan of Fig. 1. Fig. 3
a transverse section through line A B in Fig. 1, and Fig. 4 a transverse section
through line CD in Fig. 2.
E is the earthenware pipe; H spigot; I socket or faucet; K indents or grooves;
L inlet for cement, and M flat bearing surface.
.1
The socket of faucet I of each earthenware pipe E is tapered internally as shown
in Fig. 1 to allow of easy access of the spigot H of the connecting pipe. The
socket or faucet I is provided internally with the concaved recess corresponding
with the concaved recess P disposed on the outer diameter or face of the spigot H.
The spigot H is provided on the outside with one or more indents or grooves K on
each side of the concaved recess P to receive strands of picked oakum and the like
to make a tight joint to prevent the escape of cement when poured into the inlet L
to joint or connect the earthenware pipes E together. The upper outside of the
socket or faucet I is provided with the inlet L of sufficient length to allow of the
cement S being poured down one side to enable air displaced thereby to escape up
the opposite side, thus making a perfectly tight cement joint. To give a firm foot-
ing to the earthenware pipes E when laid in the ground the underside of the socket
or faucet I is provided with the flat bearing surface M moulded or formed on the
same in any convenient manner.
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
In combination with earthenware pipes the general arrangement and construc-
tion of the socket or faucet I provided with the inlet L and the internally concaved
recess to receive the spigot H having the concaved recess P for receiving the
cement S to joint the pipes together, and the indents or grooves K for the purpose
specified, substantially as described and as illustrated in the drawings.
