PROVISIONAL SPECIFICATION.
Improvements in Earthenware Pipes.
I WILLIAM GLEAVE 31 Shaw Road Heaton Moor Stockport Lancashire
Agent do hereby declare the nature of this invention to be as follows:-
:-
This invention has for its object improvements relating to earthenware pipes,
when jointed by means of cement.
Pipes made in accordance with my invention have one or more taper or cone
shaped collar rings on the outside of the spigot end, and one or more taper or cone
shaped collar rings inside the socket end, so that when two pipes are placed together
for jointing, an annular cavity is formed, and a tight joint upon the cone surfaces.
For convenience in manufacture the collar rings are made in composition and
truly cylindrical.
The socket may be provided with holes to allow the cement to be poured into
the annular cavity.
Pipes constructed in this form are more easy to joint than pipes with parallel
joint rings, as the taper spigot end will enter the socket with more clearance, and
the conical surfaces assist to guide it to its right place for making the cement
joint.
The taper rings form a somewhat similar device to friction clutch gear, the
spigot end resembling the male clutch and the socket end the female clutch.
Thus a sound joint is made, and the jointing may be performed by unskilled
workmen.
It is obvious that when more than one collar ring is formed upon the ends of the
pipes, that the ring nearest the spigot end must be less in diameter, than the second
ring, and the second ring less than the third, if three collar rings are made upon
each end of a pipe, to allow the spigot end to pass inside the socket, and the rings
in the socket must correspond.
Two collar rings on each end of the pipes will however be found sufficient for
most purposes.

COMPLETE SPECIFICATION.
Improvements in Earthenware Pipes.
WILLIAM GLEAVE Shaw Road, Heaton Moor Lancashire, Agent, 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 has for its object improvements relating to earthenware pipes
when jointed by means of cement.
I will now describe the nature of my said invention by the aid of the accom-
panying drawings which more clearly elucidate the character of my invention,
without repeating the words in my Provisional Specification.
Figure I is a longitudinal section through socket and spigot ends of earthenware
pipes, showing joint with taper collar rings and cement.
Figure 2 is a cross section showing spigot inside socket.
Figure 3 is a longitudinal section through socket and spigot ends of earthenware
pipes showing joint with two pairs of taper collar rings and cement.
Figure 4 is a cross section of pipes made like Figure 3 with spigot inside
socket.

page_text: In Figure 1. a represents a section of spigot end of the pipe inserted into the
socket showing thickness of earthenware, b the socket end of the pipe also in position
when the joint is made, c represents the composition taper ring on the spigot end
and d represents the composition taper ring on the socket end forming a joint
between the two taper composition rings, e represents the cavity filled with a
cement ring, making a firm watertight joint.
When jointing two pipes they are placed into position as shown in Figure 1 and 2
and a band of plastic clay or any material, which will prevent waste of liquid
cement, is placed round the circular opening with a space on the top side to allow
the liquid cement to be poured into the cavity.
When cement is used in a stiff mixture it may be placed into the cavity by a
trowel or other handy tool in which case the clay band is not required.
When more than one set of taper rings are employed the pipes are made with
socket and spigot ends as shown in Figure 3, a represents a section of the spigot
end of the pipe inserted into the socket, the socket end of a pipe also in position
when the joint is made, c' represents a composition taper collar ring near the end of the
spigot and c² represents a second composition taper collar ring a short distance up the
spigot. drepresents a composition taper collar ring at the bottom of the socket
and d² represents a composition taper collar ring near the mouth of the socket
leaving a short space between d¹ and d and the same distance is allowed between
the composition rings on the spigot, e represents a collar ring of cement which is
poured into the annular cavity through a hole in the socket.
When the pipes are placed together for jointing as shown in Figure 3 and 4
there is an annular cavity as shown, filled with cement at è.
It will be seen that a temporary joint is made between the taper composition
rings on the spigot and socket euds of the pipes when placed together, whilst the
annular cavity formed is filled with cement finally making a firm joint.
A second annular cavity may be formed by another set of composition taper rings,
the pipes having longer spigot and socket with a short distance between the rings
and holes for pouring in cement.
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 :-
1. Earthenware pipes made with one or more composition taper rings on the
spigot end and one or more composition taper rings inside the socket end, as shown
and described.
