IMPROVEMENTS IN SEWER AND DRAIN PIPES
Year: 1876

page_text: LETTERS PATENT to George Augustus Frederick Fowke, of the Conservative
Club, in the County of Middlesex, for the Invention of "IMPROVEMENTS IN
SEWER AND DRAIN PIPES."
Sealed the 28th March 1877, and dated the 5th October 1876.
PROVISIONAL SPECIFICATION left by the said George Augustus Frederick
Fowke at the Office of the Commissioners of Patents on the 5th October 1876.
GEORGE AUGUSTUS FREDERICK FOWKE, of the Conservative Club, in the County
of Middlesex. IMPROVEMENTS IN SEWER AND DRAIN PIPES."
My Invention has for its object improvements in the pipes above named, whereby
I obtain better effects.
The fault of the ordinary drain pipes now in universal use is, owing to their
construction, a liability to displacement, and a consequent stoppage in the drainage.
Now to obviate these defects I purpose to adopt mainly the following arrange-
ments: The pipes constructed according to my Invention are similar in dimensions
to those at present in use, but the ends instead of being cut at right angles to the
length of the pipe are cut obliquely, the result being that the series of pipes when
laid down literally become a continuous splice.
To cut pipes into lengths according to my Invention all that is required is that
the wires of the machine in which pipes are ordinarly made shall not, as at present,
be at right angles to the length of pipes being made but obliquely thereto.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said George Augustus Frederick Fowke in the Great Seal Patent Office on
the 5th April 1877.
GEORGE AUGUSTUS FREDERICK FOWKE, of the Conservative Club, in the County
of Middlesex. "IMPROVEMENTS IN SEWER AND DRAIN PIPES."
My Invention has for its object improvements in the pipes above named, whereby
I obtain better effects.
The fault of the ordinary drain pipes or pipe tiles now in universal use is that
owing to their construction or formation there is great liability to displacement, and
a consequent stoppage in the drainage. Now to obviate these defects I purpose to
[Price 4d.]

page_text: Fig. 1 is an elevation of a portion of a machine for manufacturing the pipes.
Fig. 2 is plan of series of pipes arranged according to my Invention without
sockets.
Fig. 3 shews the pipes arranged with sockets.
In cutting the pipes according to my Invention (the pipe having been first con-
structed or made by the ordinary method) I proceed thus:-The pipe a, Fig. 1, is
shewn as issuing from the machine on to stage b. On each side of the stage, and
secured thereto, are guides d arranged obliquely to the stage. In these guides d
work the rods or slides e to which the wires for cutting the pipe are fixed. Any
number of slides with corresponding guides may be used (in Fig. 1 four are shewn).
The guides are preferably joined together. For the purpose of facilitating the
work, and raising and lowering the rods or slides and wires, a chain is attached, as
shewn (which passes over a pulley), and a weight attached to the end thereof.
To cut the pipes all that is required is to work the slides, which are made to
ascend or descend by the guides in an oblique direction, the wires cutting the pipes
in manner shewn in Fig. 2.
The principal feature of the continuous splice drain pipe is the diagonal or
oblique make, which will apply to sewer and drain pipes of all sizes and shapes,
socketed or unsocketed. It is to be understood that the pipes can be constructed
by other method or machine, and the pipes can be cut to the oblique angle in
manner before described; or if desired the pipes may be moulded to the shape and
angle required.
Having now particularly described and ascertained the nature of the said Inven-
tion, and in what manner the same is to be performed, I hereby declare that I
claim in respect of the said Invention the oblique splice or joint, substantially as
the same is herein-before set forth and described; but I lay no claim to the
machine herein-before mentioned and described, as machines which will accomplish
the object and effect of my said Invention may be adopted and used.
In witness whereof, I, the said George Augustus Frederick Fowke, have
hereunto set my hand and seal, this Fourth day of April, in the year of our
Lord One thousand eight hundred and seventy-seven.
