Innoxious the Gases or Vapors from Sewers and the like.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to that system of destroying and expelling noxious gases
from sewers and drains, in which a furnace is employed at some point in the
ventilating draft-pipe, which is connected at its base with the drain or sewer, and is
elevated into the open air.
The object of this invention is to construct an improved furnace for the above-
named use, substantially as below described and claimed.
In the drawing forming a part of this specification, Fig. 1, is a vertical section of
the furnace, and a cross section of the drain or sewer on line 11 in Fig. 3. Fig. 2,
is a side elevation of a change from Fig. 1, with one side enclosure removed. Fig. 3,
is an end view looking from a point at the right of Fig. 1. Fig. 4, a vertical section
showing a change in configuration from Fig. 2; and Fig. 5, is a horizontal section
on dotted line 22 in Fig. 4, looking from a point above.
Referring to the letters marked on the drawing, D represents either a drain-pipe in
the basement of a building, which pipe leads out, and connects with the main sewer,
or it may serve to illustrate the sewer proper.

page_text: In Figs. 1 and 3, A is a pipe connecting at one end with the drain, or sewer, D,
extending upward, thence turning laterally and connecting with one end of the
furnace, B, at the upper side of said furnace. On top of the furnace, at the opposite
end, the draft-pipe, C, is connected with the furnace.
This draft-pipe in use of course extends into the open air in the ordinary manner of 5
sewer ventilating pipes.
The pipe, C, in the several figures is here shown broken.
At c are shown a series of gas burners, only one being shown in Fig. 4, located
at such a position that the top of the flame or flames comes below a horizontal plane
touching the point, r, in the several figures, and hence below the entrance of the 1
passage-way for the following gases from the drain or sewer into the furnace. The

through the furnace, is never below a horizontal plane which would touch the point, r.
Thus we have only one entrance for the flowing gases into the furnace, and that single
entrance at one of the vertical ends of the furnace, and on a plane above the flame or
flames, and only one exit at the opposite upper end of the furnace on a vertical plane
beyond the flame or flames.
The flame, or flames, is guarded from any sudden rushes of the gases or air up the
passage-way from the drain or sewer, from whatever cause, by the right-hand wall of
the furnace extending to a plane above the flame, in Fig. 1, or by the separating
partition,, hereinafter described, (shown in Figs. 2 and 4).

.
The flow of the gases through the furnace is between the top. of the flames and the
horizontal wall of the furnace. Thus the gases flow over immediately near to,
and beyond the flames, on their way out of the draft-pipe, C. The rising heat from
the flames prevents the flowing gases lowering out of their defined course, and what
are not destroyed by the first flaines are still acted upon by the heat of the succeeding
flames over which they flow.
The suction-draft from the drain, or sewer, D, and the expelling-draft up pipe, C,
are as natural and successful as the draft of an ordinary fuel-stove having a hearth
and stove-pipe.
By employing a single passage-way into, through, and out of the furnace as herein
defined, we secure better results in the draft, and are enabled to draw more noxious gases
into the furnace, and to concentrate their flow, in a manner to destroy them more
effectually than by the employment of any other furnace known to us.
These facts we have found by actual and extensive experiments and tests.
The construction in Fig. 2, is provided with a separating-wall, ¹, between the
passage-way, A¹, and the flame-chamber.
The same wall appears in Figs. 4, and 5. This wall, or partition, r, extends
laterally connecting with the side walls of the furnace, and also connects with the
bottom wall, and terminates at the upper end at a horizontal plane above the flames
leaving a space between said upper end, and the roofing-wall of the furnace. This is
considered as an equivalent to Fig. 1, but one plan will be found convenient in some
instances, and the other in other instances, according to the location of the sewer o
drain at the place where the furnace is attached.
In Fig. 4, only one flame is shown, but the same vertical passage-way for the flow
of the gases appears, and also the upper-wall of the furnace forming a roof entirely

this roofing-wall they are turned laterally and flow over, and past the flame befor
passing up the draft-pipe. The upper wall extends to, and connects with, the base o
the draft-pipe, C.
Fig. 4, shows a furnace of less dimensions and capacity than the others in Figs. 1
and 2, designed especially for small drain pipes. The space in the furnace below th

page_text: flame is greater in Figs. 1, and 2, than in Fig. 4; but this is regulated in accordanc
with the needed space in the chamber.
The furnace, should have no means of entrance, or openings in the walls, but what
are provided with means to keep them closed, to prevent the escape of noxious gases
into the building when the flames are not burning. But we make no claim to this
feature, per se.
At a is shown a gas-supply pipe, the burners, c, extending upward from the same.
Having now particularly described and ascertained the nature of our said invention
and the manner the same is to be performed as communicated to me by my foreign
correspondents I declare that what I claim is-
On a system of destroying and expelling sewer gases by means of a furnace and
flame therein, a furnace in which a suitable number of burners are located on such a
plane as will leave a narrow space between the top enclosure of the furnace and the
top of the flame, one end of this space, at one of the ends of the furnace beyond the
flame, having an exit immediately into the draft-pipe connecting the furnace at this
end, in connection with the entrance passage-way separated froin the furnace-interior,
and leading from the sewer to the top of the opposite end of the furnace, and thence
laterally opening into this end of the space beneath the top inclosure, substantially as
set forth.
