page_text: LETTERS PATENT to Edward Brooke, of Huddersfield, in the County of
York, Brick and Tile Manufacturer, for an Invention of "IMPROVEMENTS IN
DRAIN PIPES OR SANITARY TUBES, AND IN THE MEANS OR METHOD OF
"
PROVISIONAL SPECIFICATION left by the said Edward Brooke at the Office
of the Commissioners of Patents on the 10th December 1880.
EDWARD BROOKE, of Huddersfield, in the County of York, Brick and Tile
Manufacturer. "IMPROVEMENTS IN DRAIN PIPES OR SANITARY TUBES, AND IN
THE MEANS OR METHOD OF FORMING THE JOINTS THEREOF.'
Firstly. These improvements consist in forming one or more horizontal ribs or
bars on the outside of the cylindrical parts of sanitary pipes, so that when the
pipes are laid in the drain or opening, they will rest true and form a solid bed of
themselves. Instead of the ribs extending from end to end of the pipe they may
be corrugated.
Secondly. The improvements consist in the means of forming the joints of such
pipes, and this is accomplished by introducing on the spigot and in the socket of
the pipes a preparation of cement or other suitable material (either in a liquid or
other state) in the form of segments or parts of circles of the same radius or
diameter of the pipe, so that when put together they will fit each other and form a
permanent joint.

the said Edward Brooke in the Great Seal Patent Office on the 10th June
1881.
EDWARD BROOKE, of Huddersfield, in the County of York, Brick and Tile
Manufacturer. IMPROVEMENTS IN DRAIN PIPES OR SANITARY TUBES, AND IN
THE MEANS OR METHOD OF FORMING THE JOINTS THEREOF."
Firstly. These improvements consist in forming one or more horizontal ribs or
bars on the outside of the cylindrical part of sanitary pipes, so that when the
pipes are laid in the drain or opening they will rest true and form a solid bed of
themselves. If preferred, the ribs may consist of corrugations formed longitudinally
of the pipe.
Secondly. The improvements consist in the means of forming the joints of such
pipes, and this is accomplished by introducing on the spigot and in the socket of
the pipes a preparation of cement or other suitable material (either in a liquid or
other state) in the form of segments or parts of circles of the same radius or
diameter of the pipe, so that when put together they will fit each other and form
a permanent joint.
In order that my Invention may be more fully understood I hereto annex a
Sheet of Drawings illustrative thereof.
Figs. 1 and 2 represent elevation and section of a pipe having four ribs A formed
on the outside thereof. These ribs are of the same height as the socket of the pipe,
and extend nearly the whole length thereof, leaving a portion of pipe at one end
to enter the socket of the next pipe.
In Figs. 3 and 4, I represent elevation of section of a pipe in which the ribs
take the form of corrugations along the sides of the pipe.
In either construction of pipe the ribs form a support or bed which prevents the
pipes from giving way at the joints if laid on uneven ground.
The second part of my Invention is illustrated in Fig. 5, which represents the
socket of a pipe, in which are placed segments of cement or other packing to secure
a tight joint between the socket and spigot.
I lay no claim to the use of cement between the socket and spigot except in the
form of segments, as herein shewn,
In witness whereof, I, the said Edward Brooke, have hereunto set my hand
and seal, this Third day of June, in the year of our Lord One thousand
eight hundred and eighty one.
EDWARD BROOKE. (L.S.)
