Improvements in Utilizing the Waste Heat of Gas and Combustion
Explosive Motor Engines for Heating Water.
I, HENRY SUTCLIFFE the Firm of Wright Sutcliffe & Son Sanitary Engineer,
Adelaide Street Gibbet Street, Halifax, County of York do hereby declare the nature
of this invention to be as follows:-
This invention relates to Improvements in utilizing the waste heat of gas and
combustion explosive Motor Engines for heating water. In Engines constructed,
according to the said specification, a " Double-shell-boiler-Exhaust-Box," is applied in
which is inserted a coil of pipe which is connected to the "Double-shell-boiler-
Exhaust-Box," or to main circulating pipes. The "Double-shell-boiler-Exhaust-box"
is connected with the exhaust pipe of the Engine, so that the heat, (which in the
ordinary exhaust box is blown away as useless) is, by means of the circulating pipes
which are connected to top and bottom of "Double-shell-boiler-Exhaust-box" used
for purposes of water heating.
According to another arrangement, the inlet and outlet of water chamber, of
cylinder of the Engine, is connected to the "Double-shell-boiler-exhaust-box" with
pipes, whereby the hot water from the water chamber of Engine Cylinder, is
connected to the main circulating pipes, or, may be worked separately, for water-
heating purposes.
Another plan, is to connect the "Double-shell-boiler-exhaust-box" or chamber of
Engine Cylinder, either one or both, to any existing Hot Water Apparatus, whereby
the whole of the heat is used for, water heating purposes.
Dated this 4th day of October 1886.

Improvements in Utilizing the Waste Heat of Gas and Combustion
Explosive Motor Engines for Heating Water.
I, HENRY SUTCLIFFE of firm of Wright Sutcliffe & Son Sanitary Engineer, Adelaide
Street Gibbet Street, Halifax in the County of York, 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 :-
This invention relates to improvements in utilizing the waste heat of gas and
combustion explosive motor engines, for heating water in engines, constructed
according to the said specification, a double shell boiler exhaust box, in which is
inserted a coil of pipe, which is connected to the double shell boiler exhaust box, or
to main circulating pipes. The double shell boiler exhaust box is connected with the
exhaust pipe of the explosive motor Engine, so that the heat (which in the ordinary
exhaust box is blown away as useless) is by means of the circulating pipes which are
connected to top and bottom of double shell boiler exhaust box used for purposes of
water heating.
According to another arrangement, the inlet and outlet of water chamber of
cylinder of the explosive motor Engine is connected to the double shell boiler exhaust
box, with pipes whereby the hot water from the water chamber of explosive motor
Engine Cylinder is connected to the main circulating pipes or may be worked
separately for water heating purposes.
Another plan is to connect the double shell boiler exhaust box or chamber of
explosive motor engine cylinder, either one or both to any existing hot water
apparatus whereby the whole of the heat is used for water heating purposes.
Such being the nature and object of my said invention, the following is a complete
description of the same, reference being had to the accompanying drawings forming
part of this specification in which Fig. 1. is a sectional elevation of a double shell
boiler exhaust box. A is the interior into which the heated gases which enter at F
through the elbow pipe K 1. are conveyed. C is the inside shell of the boiler exhaust
box, and D is the outside of boiler exhaust box, and E is the double shell, forming the
space for heating the outside of the boiler exhaust box of the explosive motor Engine.
B is the space for the water which is to be heated and circulated round the room or
building, and in order to effect this and a quick circulation, and to take the heat out
of the waste gases as they pass through the boiler exhaust box, there is just sufficient
water space allowed to cause a rapid circulation, thus absorbing the heat out of the spent
gases as they pass from the explosive motor Engine through the boiler exhaust box as
indicated by the arrows, and through the outlet G in elbow pipe K which is almost
cold although the gases enter the elbow pipe K 1. at the inlet F at a fervent heat.
This is effected by the large heating surface and sufficient water space, so that by
means of the rapid circulation, the heat is extracted from the spent gases, as they pass
through the double shell boiler exhaust box, as shewn in Fig. 1. of the accompanying
drawings.

page_text: Fig. 2 is an end view of a gas explosive motor engine with a double shell boiler
exhaust box E, attached to the exhaust pipe of engine H connecting with the
passage F of the elbow pipe K 1. through the double shell boiler exhaust box, and through
the holes 1. in the direction indicated by the arrows, as illustrated by Fig. 1. passing
out at the elbow K through the exhaust pipe G to the open air. P is the ball valve
cistern for supplying the water to the boiler exhaust box and cylinder of explosive
motor engine, through the pipe marked O to the return circulating pipes marked T
and V. and V 2. The pipe V2 connecting with the cross tube V 3. as shewn by
Fig. 1, or with a coil, but preferably the former, for dividing and distributing the
water which when heated, flows through the tap S, as shewn at Fig. 2, and returns
through the pipes V and V 2 and tap S 1. The water to prevent over heating of the
cylinder of engine passing through the pipe V the outward flow being by the pipe A 1.
When heat
connecting with circulating pipe U from double shell boiler exhaust box.
is not required (as during the summer months) it is only necessary to close the
taps S and S 1. and open the tap on the pipe R, and the water in the double shell boiler
of which E is the outer shell will evaporate. The heated gases now passing through
the double shell boiler exhaust box, spend into the open air. When the heater is
refilled the tap on the pipe R is left open and the tap S closed. The tap S 1 is opened
slightly, till the boiler exhaust box is charged, when the tap on pipe Ŕ is closed, and
the tap S is opened, the heater is then ready for use. The relief or safety valve X
is fixed on the double shell boiler exhaust box for relief in case of a back
explosion and the tap M on the elbow pipe K 1 is to let out condensed water when
required.
Fig. 3, is another arrangement whereby the ordinary water cylinders, for preventing
the overheating of cylinder of explosive motor engines are dispensed with. The return
flow pipe T supplying the cylinder from the circulating pipes which are supplied by
the ball cistern P 1. and pipe O therefrom, and the water circulated through the
cylinder jacket of explosive motor engine, and issuing by the flow pipe A. The
pipes are fitted round the room or building, on the well known principal of water
heating.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is
Firstly. The improved double shell boiler exhaust box for utilizing the waste heat
from gas and combustion explosive motor engines, for heating water, and other liquids,
substantially as and for the purpose herein described.
Secondly. Utilizing the waste heat from gas and combustion explosive motor
engines, for heating water and other liquids, in combination with the improved

gas and other
combustion explosive motor engines, cool, and utilizing the heat substantially as, and
for the purposes herein described.

operating, substantially as and for the purposes herein described.
Fifthly. In combination, with the double shell boiler exhaust box, of gas and
combustion explosive motor engines the relief or safety valve, substantially for purpose
herein described
