PROVISIONAL SPECIFICATION.
Improvements in the Jointing of Stone-ware or Earthenware Pipes.
JOHN GEORGE KIRTLEY No. 9 Saint Thomas Street Bishopwearmouth in the
Borough of Sunderland do hereby declare the nature of this invention to be as
follows:-
My invention particularly applies to the spigot and faucet joint generally used
in this class of pipe, and for the purposes of my invention I make the spigot end
of the pipe with two raised rings one placed flush with the end of the pipe, and
the other at a convenient distance away from it so as to form a recess between them
into which when the pipes are placed in position for jointing liquid cement or other
suitable material for making the joint may be poured into the recess before
mentioned through one or more openings or holes in the faucet end of the jointing
pipe. The rings are made a working fit to the faucet, so that they may prevent
the jointing material from escaping from the recess, and thus spoiling the joint,
and are placed preferably flush with the spigot end of the pipe and the other at
such a distance from it that when the pipes are placed in position for jointing it
may be flush with the faucet end of the jointing pipe, but I do not bind myself
exactly to this position nor to the size of the recess between them, nor to the shape
of the rings on the faucet end of the pipes.

Improvements in the Jointing of Stone-ware or Earthenware Pipes.
1, JOHN GEORGE KIRTLEY, of 9 St. Thomas Street, Bisbopwearmouth,
Sunderland, in the County of Durham, Sanitary Engineer, 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:-
This invention relates to improvements in the jointing of stone-ware or earthen-
ware pipes and I will fully describe it with reference to the accompanying drawing
which shows partly in section and partly in elevation a jointed pipe of the spigot
and faucet type but it will be observed that on the end of the spigot pipe S I form
two annular enlargements 3 so as to leave a suitable recess 4 there between. In the
faucet end of the pipe S¹ I form one or more openings 5 which opening or openings
when the pipes are fitted together is or are designed to come opposite the recessed
space 4 before alluded to.
The enlargements 3 are made a working fit to the faucet so as to prevent the
jointing material from escaping from the recess 4 and thus spoiling the joint.
The drawing shows a suitable arrangement and disposition of the parts which
may be more or less varied without departing from my invention.
The inner surface of the faucet and the outer surface of the spigot where the
recess occurs may if desired be slightly serrated or notched so that when the cement
grout or other like jointing material is poured into the opening or openings at 5 it
fills up the recess and is unable to escape therefrom and after hardening the joint
will be found to be a perfect one.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
Forming on the spigot end of a pipe two enlargements adapted to enter and be
a working fit in the faucet end of a corresponding pipe thus forming a recess into
which the jointing material can be poured through an opening or openings in the
faucet substantially as and for the purposes herein set forth.
Dated this 26th day of February 1896.
