AN IMPROVED JOINT FOR SEWAGE AND OTHER PIPES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I JOHN PARSONS of Garnett Street Netherfield, Carlton, in the County of
Nottingham Clerk of Works do hereby declare the nature of my invention for
AN IMPROVED JOINT FOR SEWAGE AND OTHER PIPES to be as follows:—
The pipes are to be used for sewage drainage and other like purposes. With the
object of effectually obtaining a perfect and watertight joint I use various kinds of
Bitumen Asphalte or any other suitable quick setting substance.
There being great probabilities (when using any of these substances) of not
properly filling the joints of ordinary pipes, I make the pipes as follows.
Each pipe has a socket at one end, which socket I divide into three or more
equal or unequal parts forming segments of a circle and having such a space
between each segment as may be necessary for the admission of the jointing
substance.
On the inside of these segments of the socket a wedge shaped or other suitable
sinking is formed for increasing the strength of the joint. On the edges of the
segments of the socket, wedge shaped or other suitable sinkings are made at
intervals and being at right angle to the sinking inside the socket segments.
The other or insertion end of each pipe has a sinking corresponding with the
sinking in the socket segments, running round the outside of the pipe on that
portion of it intended to enter the socket of a pipo.
In fixing the pipes in position and to regulate the space in the socket to receive
the jointing substance I use small wedges or other packing pieces made of earthen-
ware or other hard material and these are inserted in the sinkings on the edges of
the socket segments.
In applying such jointing substances as asphalte Cement-mortar or similar
substances I use a small rammer with a flexible handle for the purpose of
compressing such substance as it is being applied.

I, JOHN PARSONS of Garnett Street Netherfield, Carlton in the County of
Nottingham Clerk of Works do hereby declare the nature of my invention for
AN IMPROVED JOINT FOR SEWAGE AND OTHER PIPES and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The pipes are to be used for sewage drainage and other like purposes. With
the object of effectually obtaining a perfect and watertight joint I use various
kinds of Bitumen, asphalte or any other quick setting substance. There being
great probabilities when using any of these substances of not properly filling the
joints of ordinary pipes I make the pipes as follows viz-Each pipe has a socket
at one end which socket I divide into three or more equal or unequal parts forming
Begments of a circle and having such a space between each segment as may be
necessary for the admission of the jointing substance.
On the inside of these segments of the socket a wedge shaped or other suitable
sinking is formed for increasing the strength of the joint and also for increasing the
space for receiving the jointing substance.
On the edges of the segments of the socket small wedge shaped or other suitable
sinkings are made at intervals and being at right angles to the sinking inside the
socket segments.
The other or insertion end of each pipe has a sinking. corresponding with the
sinking in the socket segments, running round the outside of the pipe on that
portion of it intended to enter the socket of a pipe. In fixing the pipes in position
and to regulate the space in the socket to receive the jointing substance I use small
wedges or other packing pieces made of earthenware or other hard material and
these wedges are inserted in the sinkings on the edges of the socket segments-the-
sinkings holding the wedges in position. In applying such jointing substances as
asphalte or Cement-Mortar or other similar substance I use a small rammer with a
flexible handle for the purpose of compressing the jointing substance while being
put in.

Bocket and in which small wedges are placed to hold the pipes in position while
being jointed.
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
The improved joint for sewage and other pipes in its entirety as herein before
described in this specification and as delineated in the said Drawings.
