IMPROVEMENTS IN THE ARRANGEMENT AND CONSTRUCTION OF EARTHENWARE PIPES FOR CARRYING. OFF RAIN WATER, APPLICABLE ALSO TO OTHER PURPOSES.” PROVISIONAL SPECIFICATION
Year: 1876

page_text: LETTERS PATENT to John William Dennison, of King Street, Cheapside, in
the City of London, Architect, for the Invention of "IMPROVEMENTS IN THE
ARRANGEMENT AND CONSTRUCTION OF EARTHENWARE PIPES FOR CARRYING.
OFF RAIN WATER, APPLICABLE ALSO TO OTHER PURPOSES.”
PROVISIONAL SPECIFICATION left by the said John William Dennison at
the Office of the Commissioners of Patents on the 28th February 1876.
JOHN WILLIAM DENNISON, of King Street, Cheapside, in the City of London,
Architect. *IMPROVEMENTS IN THE ARRANGEMENT AND CONSTRUCTION OF EARTHEN-
WARE PIPES FOR CARRYING OFF RAIN WATER, APPLICABLE ALSO TO OTHER
PURPOSES."
This Invention relates to improvements in pottery or earthenware pipes, whereby
certain shaped pipes of stoneware or similar material can be made (in conjunction
with certain shaped brackets or clips of terra cotta or similar material) practicably
available for conveying rain water from roofs of buildings and for other similar
purposes. For this purpose projections are formed upon the outside of the upper
or socketted end of each pipe with lugs and a projecting tenon or guard on the rim
of the socket. An indentation is also formed upon the lower or spigot end of each
pipe.
Brackets or clips of suitable form having a recess or sinking are built or let into
the building to which the pipes are applied.
The application to buildings will be as follows:-The brackets, which will occupy
the same space as an ordinary stretcher brick, are to be built in at any suitable
distance apart as the work proceeds, or in old buildings they may be inserted when
required.
The pipes, of any suitable size or length, are then fixed one above the other, and
before finally lowered into place each pipe is turned half ronud. Each pipe has
thus an independant bearing upon its own bracket, and whilst any length of
pipe can be readily taken out by being raised and turned half round, the whole
stack of pipes is doubly interlocked and immoveable by the force of wind or

page_text: otherwise. The pipes may be of various diameters and of convenient lengths,
and any that are bent in burning may be used for drain pipes so as to utilize the
same without loss.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said John William Dennison in the Great Seal Patent Office on the 25th August
1870.

OTHER
This Invention relates to improvements in pottery or earthenware pipes, whereby
certain shaped pipes of stoneware or similar material can be made (in conjunction
with certain shaped brackets, clips, or supports of terra cotta or similar material)
practically available for carrying rain water from roofs of buildings, and for other
purposes.
The application of my improved earthenware pipes and brackets to buildings will
be as follows, reference being made to the Drawings hereunto annexed and to the
figures and letters marked thereon:For the purpose of carrying my improvements
into practice projections are formed upon the outside of the upper or socketted end
of each pipe, as shown at A, A, Figures 2 and 3 of the Drawings, and open brackets,
clips, or supports of suitable form having a recess or sinking, or both recess and
sinking, as at B, B, Figure 1, are built or let into the building to which the pipes
are applied.
The brackets, which will as a rule occupy the same space as an ordinary stretcher
brick, are to be built in at any suitable distance apart as the work proceeds, or in
old buildings they are inserted where required.
The pipes, of any suitable size or length, are then fixed one above the other into
the brackets, as shown in Figures 4 and 5, and the joints left dry and open, or
stopped round according to the purpose required.
Each pipe has thus an independent bearing upon its own bracket, and whilst
any length of pipe can be readily taken out (by raising it and the one above it, and
turning them partly round) and replaced, the whole stack of pipes is doubly inter-
locked and immoveable by the force of wind or otherwise. The pipes may be of
various diameters and of convenient lengths to suit the dip required, and any pipes
that are bent in burning may be used as drain pipes so as to utilize the same
without loss.
It will thus will be seen that by my improved mode of constructing and applying
pipes of imperishable incorrosive materials, in conjunction with open brackets, clips,
or supports of similar materials, as herein-before described, they can be used advan-
tageously (especially in inaccessible parts of buildings) in substitution for metallic
pipes and clips, and they can be fixed firmly without any accumulating weight, and
at the same time in such a way that any single length of pipe can be readily taken
out and replaced without disturbing the remainder of the stack.
Having thus fully described the nature of my Invention, and the manner of
performing or carrying the same into practice, I would have it understood that I do
not intend to limit myself to the exact details herein-before described so long as the
main features of my Invention are retained, but what I claim is,―
First. The improved construction and arrangement of earthenware pipes A, and
brackets or supports B for holding and supporting the pipes used for carrying off
rain water from buildings or for other purposes, substantially in the manner herein-
before described and represented in the Drawings annexed.
Secondly. I claim the improved arrangement and method of mounting, applying,

page_text: and supporting rain water and other pipes, substantially in the manner herein-before
described and represented in the Drawings annexed.
In witness whereof, I, the said John William Dennison, have hereunto set my
hand and seal, this Twenty-second day of August, in the year of our Lord
One thousand eight hundred and seventy-six.
