Improvements in and connected with Apparatus for Burning
Garbage and House Refuse.
I HENRY EDWARD NEWTON of The Office for Patents, 6 Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, do hereby declare the
nature of this invention to be as follows:-
-
The object of this invention is to provide a simple and efficient apparatus for
destroying street sweepings, garbage, house refuse, and other refuse collected by
the scavengers' carts in towns.
In carrying out this invention, the refuse is discharged onto a table in a suitable
room, where it is sorted roughly. From this table it is conveyed in any convenient
manner to an inclined shoot, which will be closed at both ends by suitable doors.
From this shoot, the refuse falls onto the inclined grate of a furnace in a chamber
below. From the back of this furnace rises an inclined flue which passes in close
proximity to the inclined shoot, and also the sorting chamber or room, and enters
the ashpit of a second furnace used to heat boilers, with which furnace a chimney
is connected.
In the sorting room is placed a ventilator, which is in connection with the
inclined flue, and by which all effluvium arising from the refuse is drawn away and
destroyed by the heat in the flue.
The draught of the furnace may be increased by means of steam jets below the
bars, and the gases and dust passing from the second furnace, may be cooled,
condensed, and deposited, by means of a condenser, in which jets of steam and
water are arranged to act alternately in separate compartments, through which the
gases and dust are caused to pass.
The refuse is dried in the inclined shoot by the waste gases rising from the
furnace, which waste may also be used in combination with a proper supply of air,
to fire the second furnace, and all gases arising from the drying refuse in the shoot
are carried off to the flue in any convenient manner, and destroyed in the second
furnace.
"The steam produced in the boiler of the second furnace, may be used for
treating the gases as above described, or for giving motive power to suitable
engines for any purpose, the machines being situate in a room in front of, or by
the side of, the sorting chamber, and communicating, therewith, so that a draught
through the engine room may be produced by the ventilating apparatus in the
sorting room, and thus the engine room is kept free from dust and dirt.
Dated this 3rd day of July 1894.

Agents for the Applicant.

Garbage and House Refuse.
I, HENRY EDWARD NEWTON, of The Office for Patents, 6 Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, 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 :-
The object of this invention is to provide a simple and efficient apparatus for
destroying street sweepings, garbage, house refuse, and other refuse collected by
the scavengers' carts in towns, as well as other noxious organic matter.
In the accompanying drawing:-
Fig. 1 is a longitudinal sectional elevation of the entire apparatus. Fig. 2 is a
partial sectional plan on lines x x and y y of Fig. 1; and Fig. 3 is a sectional
elevation on the line 1-2 of Fig. 2.
A is a shed, into which the carts containing the refuse enter, either direct from
the ground level, or by means of a ramp or inclined road, as is now well understood
with reference to this class of apparatus.
In the floor of this shed are a series of shoots or hoppers, B, each of which
serves to guide the refuse tipped from the carts onto a table C, placed in what is
termed the sorting room D, where the refuse is roughly sorted, so as to remove
articles or substances which are obviously non-combustible, or likely to be unaffected
by heat.
The table C may be so arranged that its front end may be lowered in order to
tip the refuse into a hopper a, one side of which is formed by a sliding door a',
a rising lid a closing in the top. a³ are gutters in the floor of the hopper, by
which any excess of moisture in the garbage may drain off to a suitable pipe.
The sliding door a' gives access to an inclined shoot E, which is set at such an
angle that the refuse will be discharged therefrom automatically, that is to say,
without any extraneous help, in the way of raking or otherwise. The shoot E is
provided at bottom with a hinged or other door b, which, when closed, retains the
refuse in the shoot until it is dry, and when opened, allows it to fall into the
destructor furnace G. The door may be closed, and supported, when closed, by a
'chain, or it may be operated by a lever handle on the pivot, or in any other
convenient manner.
The furnace G is provided with an inclined grate, the inclination of which is
such, that the refuse, as it drops from the inclined shoot E, will fall well to the
front, and the necessity for raking it forward, as in the present type of destructor
furnace, is obviated.
H is an inclined flue leading from the furnace G to a horizontal flue H', and the
shoot E practically forms the top of this flue. The shoot E will thus become
heated by the waste heat arising from the burning refuse in the furnace, & the
refuse, which is retained in the shoot E, to form a subsequent charge for the
furnace, is almost completely dried, prior to being deposited on the grate by
the opening of the lower door b, and will therefore spread itself more evenly
over the fire, and burn with greater facility than it would if it contained
moisture.
During the drying of the refuse in the shoot E, noxious vapours will obviously
arise, and these are drawn off by means of a steam or other injector J through an
opening in the upper part of the top of the shoot E, near the sliding door a¹,
and through the small flue 62, which conveys them to the injector J, by which the
vapours are driven into the ashpit of the furnace G, whence they pass with the'
injecting medium into the fire, and are destroyed.

page_text: This is the arrangement which is preferred, but the noxious vapours may be
made to pass direct to a steam generator furnace, to be presently described.
G' is a second destructor chamber provided with a charging shoot G³, closed at
its upper end by a suitable lid. This second chamber, which is shewn at Figs. 2
& 3, has no grate, and it is heated by the fires in the furnaces on each side of it,
after the manner of a retort. The offal or other refuse placed in this chamber G¹,
is thus incinerated, & the fumes or vapours arising therefrom pass through
openings in the side walls of the shoot G, into the flue H.
In practice, a series of destructor furnaces, varying in number according to the
requirements of the district in which the apparatus is used, are ranged side by
side, but in most cases it will be found useful to employ the destructor chamber G₁
between two destructor furnaces G.
It will be obvious that both chambers G G¹ will be provided with doors, by
which the clinker, etc., may be discharged from time to time.
When there are a series of furnaces, the horizontal flue H¹ will be common to
all, and this flue will be in connection with the ashpit of the furnace of a steam
generator K, of any convenient form; consequently all the gases arising from the
destructors will have to pass through this second furnace, where all the noxious
properties will be destroyed.
The products of combustion from the steam generator furnace, before passing
to the chimney, are treated in a purifier L, consisting of chambers formed by
vertical walls having openings alternately at top & bottom, so that the gases will
be caused to take a zigzag course.
The chambers are thus alternately uptake and downtake chambers, and the
entrance to the purifier is at the bottom of the first uptake chamber.
The uptake chambers are provided at bottom with steam jets e, which inject
steam upwards, while each downtake chamber is provided at top with a rose or
jet, injecting water, preferably in the form of spray, downwards.
By these means, not only a forced draught is induced in the purifier L, which
will react throughout the whole apparatus, but at the same time the products of
combustion will be thoroughly washed, and further deodorised, so that when the
vapours enter the chimney shaft or uptake M, they will be quite inodorous &
innoxious.
N is a ventilator placed in the sorting room D. and by the action of which, the
air in the sorting room is kept wholesome. The ventilator will be driven from
the engine room P, and will, by means of a discharge pipe N¹, connect with the
horizontal flue H¹, or other convenient part of the apparatus.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed (as communicated to me from
abroad), I declare that what I claim is :-
1. Utilizing the heat developed in a garbage-destructor furnace, to dry a fresh
charge of garbage placed in a charging shoot or hopper, and also to carbonise or
