moving through said retort is destroyed by burn
ing, whereby at the termination of the process,
1;,- the resulting product or refuse is of a sanitary
nature which may be disposed of without injury
to the public‘health, comfort and convenience.
Other objects of the invention are to provide an
incinerator that will be superior in point of sim
00 plicity, inexpensiveness of construction, positive
“‘
ness of operation, and facility and convenience in
use and general efficiency.
In this speci?cation and the annexed drawings,
the invention is illustrated in the form considered
. to be the best, but it is to be understood that
the invention is not limited to such form, because
it may be embodied in other forms; and it is also
to be understood that in and by the claim fol
lowing the description, it is desired to cover the
0: invention in whatsoever form it may be em
bodied.
In the accompanying drawings:
Fig. 1 represents a side elevation of an in
cinerating plant constructed in accordance with
CD 2.1 my invention.
Fig. 2 is a plan View of Fig. 1.
Fig. 3 is an end elevation of Fig. 2.
Fig. 4 is a section taken through Fig. 1 on the
~10
line 4-4.
Fig. 5 is a section taken through Fig. 2 on the
line 5—5.
In detail the construction illustrated in the
drawings comprises an elevated ramp I, running
from the ground level to an elevated dumping
5 platform 2, whereby trucks loaded with garbage,
refuse and the like, may be driven onto the plat
form and the contents of the said truck dumped
into a series of collection bins 3 which lie directly
below’ the platform 2, each of said bins having
50 inclined and downwardly converging bottom walls
which terminate in a discharge chute 4 at the
bottom thereof. The discharge end of the bins 3
overlie the upper run of an endless belt 5, a por
tion of which runs in a pit 8 beneath the bins 3.
55 The remaining portion of the belt 5 is inclined
matically feeding the refuse to be disposed of, into
the retort 9.
The retort 9 is cylindrical in shape and the 15
outside thereof is provided with rings lB-—I 0 which
are supported in bearings I |—H to permit rela
tively free rotation of the said retort. A gear I2
is provided around the retort and in meshing
engagement with a driving pinion IS on a motor 20
14, said last mentioned unit forming the 'pro
pulsion means of the retort. The entrant end of
the retort 9 is at a slightly higher elevation than
that of the discharge end thereof, and said en
trant end of the retort is rotatably journaled on 25
one side of a casing l5, and the said casing and
retort at the point of connection are open to
communication with each other. The casing l5
may be termed an explosion chamber as will later
appear from the description of the invention. The 30
discharge end of the retort 9 abuts in rotatable
relationship against one side of a combustion
chamber 18, and with which the interior of said
retort communicates. The refuse that is dis
charged into the entrant end of the retort 9, 35
due to the slope of the said retort and the rota
tion thereof, gradually works its way through
the length of said retort. As the refuse is pass
ing through the retort it is subjected to heat
developed by a furnace l8 and thence through a 40
pipe or conduit it into the combustion chamber
16. The refuse itself contains sufficient combus
tibles that will ignite with the application of heat
thereto, and if necessary, either a gas or oil burner
20 located in the heating box IE may be used to 45
develop flames to generate additional heat to that
coming from the boilers ll. A temperature of
from 1200° to 4000" F. may be created in the re
tort and such a temperature range is suf?cient
to completely destroy all of the garbage and
rubbish moving through said retort. The com
bustible nature of the refuse itself supplies a
goodly portion of the ?re necessary to destroy
the rubbish, and. the rotary movement of the 55
"2, 107,507
2
retort insures that all of the said ‘refuse will be
completely burned=
The smoke and products of combustion given
off by the burning refuse, flows in a natural path
toward the casing l5, and any gases given off dur
ing the burning of the refuse which may be of a
combustible nature and which may explode, thus
creating a pressure within the retort in excess of
a capacity which may be accommodated by the
retort, is allowed. to escape through expansion
door 22 provided on the chamber l5. Such ex
pansion would be momentary and as soon as the
pressure would be relieved from the retort, the
doors would automatically close. However, in
order to pull the smoke, names and the gases of
combustion through the retort, I have provided a
pipe 23 in communication. with the chamber I5,
which pipe, at its other end, connects with a wash
er 24 for washing the solids and toxic gases out of
20 the smoke, ?ames and products of combustion. A
pipe 25 leads from the washer 24 to a suction fan
26, and from the suction fan a conduit 27 com
municates with, the furnace l8. The suction fan
26 sucks or pulls the gases, etc., through the re
' tort and washer, and discharges any heated gases
which may remain back into the furnace 58, at
which point a portion of the gases is directed into
an upper compartment 28 of the furnace l8, and
the rest into a lowerrcompartment 29, where the
gases are burned and completely destroyed. The
heat generated thereby is utilized for preheating
gases contained in the compartment 28 where
from they are reconveyed to the combustion
so
chamber IS. The combustion which takes place
in the compartment 29, being of-a high tempera
35
ture, is forced through the boilers H and isthere
by utilized for generating steam. The gases are
drawn through the boilers and out into the atmos
phere by means of a fan 33. The entire system of
40 furnace, combustion chamber, retort, explosion
chamber and washer comprises 'a closed circuia
tory system and the refuse passing through said,
retort is burned or destroyed under a forced draft.
In order to eliminate any obnoxious fumes es
caping to the atmosphere from the collection
45
of without injury 'to the ‘public health, as ash re
mover 35 being provided beneath the combustion
chamber l6.
With my system of incineration, the garbage
and refuse is completely disposed of without any
part of portion of the products of combustion giv
en off during the incineration escaping into the
air in the form of soot or smoke as is commonly
the practice. In my apparatus the continuous re
circulation of a certain amount of the used gases 10
of combustion creates an economy in the opera
tion of the entire plant, and materially reduces the
amount of fuel necessary to effect efficient incin
eration. Furthermore, the operation of my in
cinerator is odorless in that the obnoxious gases
given off during the incineration are captured and
put through a washer, after which the remainder
of said gases are returned to the furnace and re—
circulated.

'
In order to care for the intense heat developed
in my retort, I have lined the same with ?reproofe
or other desirable refractory materials, it being
necessary because of the forced draft system and
the intensity of the heat developed, to construct
the apparatus of material which will not break
down under the temperatures used.
.
Having thus described this invention, what I
claim and desire to secure by Letters Patent is:
In an apparatus for destructively disposing of
garbage; a combustion chamber; an inclined ro
tary retort for advancing the refuse to be burned
toward said combustion chamber; means in c0m~
munication with the end of said retort opposite
said combustion chamber for feeding ,thereinto
materials to be burned; an explosion chamber in .
communication with said last mentioned end of
said retort; a furnace; a passageway connecting
said furnace with the combustion chamber; a con- »
duit connecting the said furnace with said ex
plosion chamber; a blower for maintaining cir
culation through the conduit, passage way, com
bustion chamber, retort and explosion chamber,
said blower creating a forced draft circulation
through the system; means for moving the refuse
through the retort in moisture extracting relation 45
chamber 1, I have provided a pipe 33 which, at one ' with the ‘not gaseous products in opposite rela
50"
end, communicates with the collection chamber
‘I, and at its other end with the pipe 23. The draft
created'in the pipe 23 by the fan 26 will draw all
obnoxious gases into the pipe 23 and further into
the furnace l8.
7
By the time the refuse which enters the retort
is discharged out of the discharge end of the same,
into the combustion chamber l6,,it falls on the
' floor of said'chamber in the form of an ash or
similar innocuous product which may be disposed
40
tion to the direction of movement of the products
of combustion therethrough; means for contin
ueusiy burning in and venting to the atmosphere
through the furnace a selected portion of the gas
given off in the reduction of the refuse; and means
for discharging from the‘combustion chamber the
final products resulting from the termination of
the incineration process.
