An Improvement in Cremating Apparatus.
I, HAROLD IMRAY of No. 28 Southampton Buildings, Chancery Lane in the
County of London, Patent Agent, do hereby declare the nature of this invention
to be as follows:-
Several arrangements of cremating apparatus have been proposed or are in use.
In one arrangement the body is placed on a refractory plate and pushed into a
furnace chamber whence, after incineration, the plate is withdrawn to collect the
ashes. This method involves considerable difficulties and has therefore been
practically abandoned. According to another arrangement, the body is placed on
a stationary grating through which the ashes are intended to drop to a receptacle
below. In this arrangement, if the openings of the grating are small, a large
portion of the ashes does not drop through them, and if they are large, fragments
of the body, only partially consumed, drop through. In another arrangement the
body is placed on a-corrugated furnace bed presenting hollows to receive the ashes,
which are afterwards removed by a rake fitting the corrugations of the bed. In
this arrangement notwithstanding these corrugations, the incineration of the under
parts of the body goes on too slowly, and the corrugations interfere with the proper
raking out of the ashes.
This invention is intended to remedy the defects of the methods hitherto in use,
by adopting a construction of the following description. The furnace chamber is
divided into two compartments, an upper and a lower compartment, by a grated
partition on which the body is laid. The flames or hot products of combustion
from a furnace enter the lower compartment, or there may be a number of gas
burners arranged in the lower compartment, so that the flames and hot gases pass
up through the grating, acting on all parts of the body, the waste gases and fumes
escaping by flues from the upper compartment. When the incineration is complete,
a rake passed along the grating drives through an opening into the lower compart-
ment such portion of the ashes as may have rested on the bars, and another rake
passed along the floor of the lower compartment pushes all the ashes thence into an
urn or receptacle placed at the mouth of a descending channel at the end of the
compartiment.
Suitable mechanism is provided to open the door of the cremating chamber, to
move the body or coffin on to the grating, and to close the door.

COMPLETE SPECIFICATION.
An Improvement in Cremating Apparatus.
I, HAROLD IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in
the County of London, Patent Agent, do hereby declare the nature of this inven-
O tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
Several arrangements of cremating apparatus have been proposed or are in use.
In one arrangement the body is placed on a refractory plate and pushed into a
furnace chamber whence after incineration, the plate is withdrawn to collect the

practically abandoned. According to another arrangement, the body is placed on
a stationary grating througli which the ashes are intended to drop to a receptacle
below. In this arrangement, if the openings of the grating are small, a large
portion of the ashes does not drop through them, and if they are large, fragments
of the body, only partially consumed, drop through. In another arrangement the
body is placed on a corrugated furnace bed presenting hollows to receive the
ashes, which are afterwards removed by a rake fitting the corrugations of the bed.
In this arrangement notwithstanding these corrugations, the incineration of the
under parts of the body goes on too slowly, and the corrugations interfere with the
proper raking out of the ashes.
This invention is intended to remedy the defects of the methods hitherto in use,
by adopting a construction of the following description.
The furnace chamber is divided into two compartments, an upper and a lower
compartment, by a grated partition on which the body is laid. The flames or hot
products of combustion from a furnace enter the lower compartment, or there may
be a number of gas burners arranged in the lower compartment, so that the flames
and hot gases pass up through the grating, acting on all parts of the body, the
waste gases and fumes escaping by flues from the upper compartment. When the
incineration is complete, a rake passed along the grating drives through an opening
into the lower compartment such portion of the ashes as may have rested on the
bars, and another rake passed along the floor of the lower compartment pushes all
the ashes thence into an urn or receptacle placed at the mouth of a descending
channel at the end of the compartment.
Suitable mechanism is provided to open the door of the cremating chamber, to
move the body or coffin or to the grating, and to close the door.
Figure 1 of the accompanying drawings is a longitudinal and Figure 2 is a
transverse section of a creating apparatus according to this invention.
The hody or coffin is placed in the chamber A on the grating B of refractory
material, the door C being then closed.
Underneath the grating is a smooth floor D on which the ashes drop through the
interstices of the grating. A rake E pushes such of the ashes as remain on the
grating down the opening G, and another rake F pushes the ashes along the floor D
to the passage H by which they descend to the urn I.
When gas is employed as combustible, jets J are arranged as shewn under the
grating B and the products of combustion escape by flues I above the grating.
The jets may be arranged so as to throw the greatest amount of heat on the trunk
of the body which requires the most burning. Instead of gas, flame or highly
heated products of combustion from an external furnace may be supplied to the
chamber under the grating B.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is
Cremating apparatus consisting of a furnace chamber divided into an upper and
a lower compartment by a refractory grating on which the body is laid, the lower
compartment having a smooth floor to receive the ashes and being provided with
gas jets or flame and the upper compartment having flues for escape of products of
combustion, substantially as described.
