Figure 6 is a vertical central section, anu,
Figure 7 is a plan of the cesspan-receiving hopper, that is, of the hopper which is
provided over the main furnace for receiving the cesspans and for facilitating the
emptying of same.
Figure 8 is a central longitudinal section of a certain attachment which I propose to
apply to the larger forms of my apparatus to facilitate the discharge of refuse into it
as hereinafter described, and,-
Figure 9 is a section of part of a pair of the inclined plates upon which the refuse
to be destroyed is fed.
Similar letters of reference indicate the same parts in all the figures.
AA (Figures 1, 2 and 9) represent the inclined plates upon which as hereinbefore
mentioned the refuse to be destroyed is discharged whilst B represents the fire-place
wherein the necessary heat is generated for converting such refuse into gases and
steam. These latter pass through the flue C into the lower part of the gas-producer
or incandescent fuel holder D which is preferably situated at the other end of the
apparatus and is provided with a fire-door d, fire-bars d' and ash-pit d. In passing
through the mass of incandescent fuel in this gas-producer, the gases and steam are
converted into carbonic oxide gas, which then passes through a flue E leading from the
top of said gas-producer down into a large combustion chamber F where said carbonic

page_text: oxide gas is completely consumed by admitting a small quantity of either hot or cold
air but preferably the former through a conveniently arranged damper ƒ whilst the
products of combustion pass along a flue g into a conveniently arranged chimney or
iron funnel G.
The liquid contained in the material under treatment passes over the lower ends of
the plates A around the downwardly and rearwardly curved edges a thereof (as
clearly illustrated in Figure 3) and drops down on to a tray H resting on a bed of
sand which is provided beneath said plates just above the combustion chamber F.
By this means l'ensure a more rapid evaporation of such liquid than has been the
case with destructors as hitherto constructed, whilst the steam arising therefrom is
utilised in the combustion of the refuse by passing it with the other products of
combustion through an incandescent mass, as hereinbefore described.
I provide the gas producer D with a water-jacket I and if the natural draft of the
destructor is not sufficient, I lead a steam pipe i (Figures 1, 3 and 4) from above
the water line in a steam and water reservoir I connected with such water-jacket
into the chimney G, whereby an increase of draft may be provided for, as will be well
understood, whilst the steam and water in said water jacket may be utilised for
cleansing the cesspans or other receptacles (either within the hopper J or otherwise)
in which the refuse is conveyed to the destructor, a pipe being led from the steam
pipe in order to obtain a supply of live steam therefrom, whilst another pipe 2 leads
from below the water line in said reservoir 1'. These two pipes both lead into a
suitably arranged and constructed nozzle or injector whereby the mixture of steam
and water may be discharged into the cesspan or other receptacle to be cleansed.
receiving hopper J for the latter may (when cesspans are intended to be emptied
into the destructor) be arranged and constructed as illustrated in Figures 1, 3, 4,
and 7, that is, with a holder j for said pan mounted upon an axle having a crank-
handle at one end whereby said holder together with the pan can be turned over
bodily to empty the contents of the latter on to the topmost inclined plate A which
may if preferred or if found desirable be protected by brickwork from the intense heat
of the flames. In order to prevent the cesspan from falling out of the holder j, the
arms of the latter may be bent inwards near their ends (as shown at j*, Figure 6) to
form clips to support said pan.
A
The lid of the hopper J is arranged to slide over said hopper and to fit closely
thereupon, and it is made high enough to enable the lid of the cesspan to be lifted
up into it by depressing the outer end of a long lever whose inner end is hook-
shaped and is adapted to engage with a cross-shaped loop or handle je upon said cess-
pan lid when the lid 3 of the hopper is slid into position. The fastenings of the
cess-pan lid are of course loosened when the cesspan is placed within the hopper J,
then the inner end of the lever jo is caused to engage with the loop upon said lid
which is then raised clear of the cesspan by depressing the outer end of said lever and
can then be held in such position by engaging the outer end of said lever under a
suitably arranged spring or other retaining clutch or catch whilst the cesspan is
being turned over to empty its contents into the furnace.
If preferred, instead of using this arrangement, the device illustrated in Figure 8
may be adopted. It consists of a chamber K provided over an opening L in the roof
of the destructor, said opening being closed by a sliding plate which can readily be
removed when it is desired to empty a tip truck for instance into the destructor. In
order that said truck may be conveniently run into the chamber K, rails k¹ are provided
which are turned up at their inner ends to limit the travel of the truck which when in
position alongside the opening L may be enclosed in the chamber K by lowering the
door which latter may if preferred be arranged to slide instead of being hinged as
illustrated. The truck may be tipped from the outside of the chamber K by any
convenient means, after which the sliding plate k can be closed and the truck removed
from the chamber K.
If found desirable, the material upon the topmost plate A may be raked off same
when it has dried sufficiently and be allowed to fall on to the fire-place B thereby
effecting a considerable saving in the fuel required.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is :-
First. In a destructor for town and other refuse such for instance as excreta, offal,
house waste or garbage, the employment of a number of inclined plates (such as A)
upon which the refuse to be destroyed can be fed, each of said plates having its lower
edge curved downwardly and rearwardly (vide a Figures 1 and 9) in order to separate
the liquid from the solid parts of such refuse and to allow the former to fall on to a
heated tray (such as H) whereby it will be converted into steam substantially as and
for the purposes specified and as illustrated in said Figures 1 and 9 of my
drawings.
Second. In a destructor for town and other refuse, such for instance as excreta,
offal, house waste or garbage, the employment of a tray (such as H) resting upon a
sand bath or body of sand (such as h), on to which tray the liquid from such refuse
can fall, said tray being exposed to heat preferably both above and below same in order
to rapidly convert such liquid into steam, substantially as and for the purposes specified
and as illustrated in my drawings.
Third. In a destructor for town and other refuse such for instance as excreta, offal,
house waste and garbage, the employment of a gas producer or incandescent fuel
holder (such as D) for converting the gases and steam arising from such refuse into
carbonic oxide gas, said producer or holder being provided with flues leading the one
from the main furnace (that is from the one wherein the refuse is first incinerated,
that is, converted into gases and steam), whilst the other leads to a combustion
chamber (such as F) where the final destruction of such gases is effected: substantially
as and for the purposes herein described and explained and as illustrated in my
drawings.
Fourth. In a destructor for town and other refuse such for instance as excreta, offal,
house waste and garbage, the combination with a hopper or receiver (such as J) of a cess-
pan holder (such as 1) supported upon an axial support (such as j¹) provided with a crank
or other handle (such as ), together with some suitable means for securing a cesspan
or other similar receptacle in said holder, the whole being so constructed and arranged
that said cesspan or other receptacle may be readily placed therein and be turned
upside down to empty the contents thereof into the destructor: substantially as and
for the purposes specified and as illustrated in Figures 1, 3, 4, 6 and 7 of my
drawings.
