Improvements relating to the Utilization of Waste Gases from Gas Engines for Heating Purposes.

page_text: Improvements relating to the Utilization of Waste Gases from Gas
Engines for Heating Purposes.
I HENRY NIELD BICKERTON, of 6 Richmond Street, Ashton-under-Lyne, Gas
Engineer, do hereby declare the nature of this invention to be as follows:-
The improvements relate to the utilization of waste gases for heating purposes,
such improvements being applicable more especially to works and other places
where a gas engine is employed, and have for object to obtain a ready means of
heating water, food or other material, in a simple and effective manner, by the
exhaust from such gas engine.
To accomplish this and to effect my improvements, I provide a casing of suitable
form, by preference cylindrical, and of cast iron or other suitable metal, and
furnished with an inlet and outlet for the passage therethrough of heated gases.
Within this casing, I place an inner cylindrical or other vessel, of copper or
other suitable metal, and of such thickness as to permit of ready heating, which
cylindrical vessel may be capable of removal from the outer casing, or, if preferred,
be attached as a fixture, and is caused to project through the top cover of the outer
casing, which cover is provided with suitable luting to prevent the escape of the
gases. A sufficient space is provided between the outer casing and this inner
vessel for the free passage and action of the exhaust gases.
A two-way valve is provided at the gas inlet of the apparatus, whereby the
gases, when not required for heating may be deflected into a branch nipe outside
the apparatus, which branch pipe is by preference carried up beside the apparatus,
and connected to the exit pipe of the heater or otherwise.
The internal copper or other cylinder, which is suitable for liquids, may have
an outlet pipe carried through an opening in the outer casing, and a tap provided
for drawing off. The cylinder may also be provided with a lid or cover.
I also prefer to cast or form an inner compartment or chamber within the outer
casing, for the purpose of heating solids and other matters, and in which
compartment is a door or other communication with the exterior of the apparatus.
Variations in detail may be made, such as in the method of connecting the pipes
to the heater, the form and material of the outer casing, inner vessel and com-
partment, and in the method of attaching and jointing the various parts, without
departing from the peculiar character of the invention.

I, HENRY NIELD BICKERTON, of 6 Richmond Street, Ashton-under-Lyne, Gas
Engineer, 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 improvements relate to the utilization of waste gases for heating purposes,
such improvements being applicable more especially to works and other places
where a gas engine is employed, and have for object to obtain a ready means of
heating water, food or other material, in a simple and effective manner, by the
exhaust from such gas engine.
To accomplish this and to effect my improvements, I provide a casing of suitable
form, by preference cylindrical, and of cast iron or other suitable metal, and
furnished with an inlet and outlet for the passage therethrough of heated gases.
Within this casing, I place an inner cylindrical or other vessel, of copper or
other suitable metal, and of such thickness as to permit of ready heating, which
cylindrical vessel may be capable of removal from the outer casing, or, if preferred,
be attached as a fixture, and is caused to project through the top cover of the outer
casing, which cover is provided with suitable. luting to prevent the escape of the
gases... A sufficient space is provided between the outer casing and this inner
vessel for the free passage and action of the exhaust gases.
A two-way valve is provided at the gas inlet of the apparatus, -whereby the
gases, when not required for heating may be deflected into a branch pipe outside
the apparatus, which.branch pipe is by preference carried up beside the apparatus,
and connected to the exit pipe of the heater or otherwise.
The internal copper or other cylinder, which is suitable for liquids, may have
an outlet nipe carried through an opening in the outer casing, and a tap provided
for drawing off. The cylinder may also be provided with a lid or cover.
I also prefer to cast or form a compartment or chamber within the
casing, for the purpose of heating solids and other matters, and in which
compartment is a door or other communication with the exterior of the apparatus.
But that the improvements may be better understood, I will, with the aid of
the accompanying drawings proceed more fully to describe means employed by
me. :

DESCRIPTION OF DRAWINGS.
Fig. 1, is a vertical section, and Fig. 2. an elevation, of apparatus arranged
according to one form of my improvements.
The same letters indicate corresponding parts wherever they occur.
a. is the outer casing of the apparatus, provided with an inlet a¹. and outlet a
for the passage of the heated gases, which are allowed free action within the
annular space b.
+
c. is the inner vessel, suitable for liquids, and which, in the example shown, is
capable of removal from the outer casing a. i,
Suitable luting d. is provided to prevent the escape of gases through the cover
of the outer casing.
**:
A two-way valve, not shown in the drawings, is provided at e. whereby the
gases may be deflected, when desired, into the branch pipe f. in connection with
the exit pipe 9...
The internal cylinder or vessel.c. may have an outlet pipe, carried through a

page_text: hole in the outer casing (as shown in dotted lines) and provided with a tap c' for
diawing off.
1. is a cover for the cylinder c.
k. shows one form of compartment or chamber for heating food or other solid
matters, such compartment surrounding the upper portion of the cylinder c., and
receiving its heat therefrom, by radiation; but I may situate such compartment
within the lower part of the apparatus, if desired, in which case an opening thereto
would be formed in the outer casing a. and the vessel c. would be arranged so as to
leave the necessary space to accommodate such compartment.
11. are doors or covers for the compartment k. Variations in detail may be
made, such as in the method of connecting the pipes to the heater, the form and
material of the outer casing, inner vessel and compartment, and in the method of
attaching and jointing the various parts, without departing from the peculiar
character of the invention.
Having now particularly described and ascertained the nature of my saiu inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
In apparatus for utilising waste gases from gas engines, for the purpose of
heating water, food or other material, the combination of an outer casing, an inner
cylinder or vessel, and a compartment for solids, arranged in manner and for the
purpose substantially as herein shown and described.
