Year: 1872

page_text: LETTERS PATENT to Henry Stott, of Greetland, near Halifax, in the
County of York, Cotton Warp Maker, for the Invention of "In-
PROVEMENTS IN VENTILATING SEWERS AND DRAINS."
Sealed the 7th May 1872, and dated the 13th February 1872.
PROVISIONAL SPECIFICATION left by the said Henry Stott at the
Office of the Commissioners of Patents, with his Petition, on the
13th February 1872.
I, HENRY STOTT, of Greetland, near Halifax, in the County of York,
Cotton Warp Maker, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN VENTILATIng Sewers and DRAINS," to be as follows:-
This Invention consists in connecting sewers and drains by pipes with
the furnaces of steam boilers or other furnaces where there is a strong
draught or high chimney. For this purpose I enclose the ashes place
by a door and introduce or connect the pipe from the sewer or drain to
the ashes place in any convenient manner. In some cases or places
I may dispense with the sewer or drain traps for the purpose of admitting
a sufficient supply of air.

filed by the said Henry Stott in the Great Seal Patent Office on
the 13th August 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
STOTT, of Greetland, near Halifax, in the County of York, Cotton Warp
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of February, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Henry Stott, Her special licence that I,
the said Henry Stott, my executors, administrators, and assigns, or such
others as I, the said Henry Stott, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN VENTILATING SEWERS
AND DRAINS," upon the condition (amongst others) that I, the said Henry
Stott, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Stott, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement and accompanying Sheet of Drawings (that is
to say:
-
This Invention consists in connecting sewers and drains by pipes with
the furnaces of steam boilers or other furnaces where there is a strong
draught or high chimney. For this purpose I enclose the ashes place
(by a door) and introduce or connect the pipe from the sewer or drain to
the ashes place in any convenient manner. In some cases or places

page_text: I may dispense with the sewer or drain traps for the purpose of admitting
a sufficient supply of air.
Such being the nature and object of this my said Invention, I will now
proceed to describe the same in detail, and in order that the Invention
may be clearly understood I have hereunto annexed a Sheet of Drawings
illustrative thereof, and have marked the same with figures and letters
of reference, the same letter referring to the same part in the various
views.
At Fig. 1 is shewn elevation of main sewer or drain steam boiler
and the connecting pipes.
Fig. 2 is a side clevation of steam boiler and connecting pipes, the
main sewer or drain being in section.
"
وو
A is the main sewer or drain; B, B, are pipes connecting the ashes
places C, C, of the furnaces D, D, with the sewer or drain A. The said
"ashes places
are enclosed as shewn by doors E, so as to exclude air
other than that drawn by the draught of the furnace and chimney from
the sewers or drains. In some cases in order to thoroughly exhaust the
noxious gases contained in the sewers or drains it may be necessary to
admit an additional supply 'of atmospheric air to the sewers or drains,
this I effect by or through the gulley pipes F, in which case the "trap'
of the gulley will be dispensed with. In all cases however it will be
observed that the furnace to which a sewer or drain is connected for the
purpose of ventilation or removing the noxious air, gases, or vapours
therefrom the connections must be so arranged that the furnace can
only receive its supply of air to support combustion from such sewer or
drain (except when the doors E are open for the removal of the ashes),
consequently it must of necessity be continually exhausting the said
sewer or drain of the air, gases, or vapours, and which must also pass
through the fire and thereby be consumed or purified in their passage
and before again mixing with the common atmosphere.
Having thus described the nature of my said Invention, and shewn by
Drawings in what manner the same is or may be performed or carried
into practical operation, I would have it understood that I do not con-
fine myself to any particular construction or arrangement of the pipes
or connections to be used, but I claim connecting sewers or drains with
furnaces in such manner that any such furnace can only be supplied

page_text: with air to support combustion from the sewer or drain to which it is
connected.
In witness whereof, I, the said Henry Stott, have hereunto set my
hand and seal, this Tenth day of August, in the year of our
Lord One thousand eight hundred and seventy-two.
