PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Rapid Water Heating by Gas or
the like.
We, JOHN FREDERICK SIMMANCE, 40, Weltze Road, Hammersmith, W., Civil
Engineer, and JACQUES ABADY, 18, Rockley Road, West Kensington Park, W.
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
66
In apparatus for heating water rapidly by gas, petroleum, spirit &c. &c..
known as
"water heaters or geysers we propose arranging the incoming
jet of cold water so that it travels for a sufficient distance along the path, and in
the same direction as the outgoing products of combustion (thus acting as a
jet or spray exhauster) and falling when its impetus is expended into a receptacle
provided. From thence the water passes into the heating chambers or spaces
and coming in contact with the heated products or with surfaces exposed to the
products and flame heat becomes rapidly raised in temperature and passes away
through a convenient conduit for use. By these means the products can be
drawn through the various heating chambers or spaces, which chambers or
spaces can thus be multiplied so as to extract all the heat from the products-parts
of which heat has hitherto necessarily been left in them for ensuring their making
their own exit.
By the arrangement we propose the exhaust is mechanical and not by gravity.
For an apparatus in which it is required that the products of combustion
shall not come in contact with the water to be heated we propose attaching to a
convenient external part of the outlet flue a small turbine (in a suitable case) the
spindle of which will be geared through a stuffing box if necessary with an
exhausting fan in the flue itself. The incoming water will first work this turbine
& thus actuate the exhausting fan after which, its impetus being lost it will
pass away to the heating apparatus & be raised in temperature.
For supplying the heat to the heating chambers we propose utilising for gas,
the form of burner described by Kern in his Specification No. 294, January 5th,
1897 or we may use any good form of Bunsen or white-flame gas burner, or a
suitable flame obtained by the combustion in a good burner of petroleum, spirit,
acetylene or the like.

In apparatus for heating water rapidly by gas, petroleum, spirit or the like
known as water heaters ΟΙ geysers we propose arranging the incoming
jet of cold water so that it travels for a sufficient distance along the path, and in
the same direction as the outgoing products of combustion (thus acting as a
jet or spray exhauster) and falling when its impetus is expended into a receptacle
provided. From thence the water passes into the heating chambers or spaces
and coming in contact with the heated products or with surfaces exposed to the
products and flame heat becomes rapidly raised in temperature and passes away
through a convenient conduit for use. By these means the products can be
drawn through the various heating chambers or spaces, which chambers or
spaces can thus be multiplied so as to extract all the heat from the products-parts
of which heat has hitherto necessarily been left in them for ensuring their making
their own exit.
By the arrangement we propose the exhaust is mechanical and not by gravity.
For an apparatus in which it is required that the products of combustion
shall not come in contact with the water to be heated we propose attaching to a
convenient external part of the outlet flue a small turbine (in a suitable case) the
spindle of which will be geared through a stuffing box if necessary with an
exhausting fan in the flue itself. The incoming water will first work this turbine
and thus actuate the exhausting fan after which, its impetus being lost it will
pass away to the heating apparatus and be raised in temperature.
For supplying the heat to the heating chambers we propose utilising_for gas,
the form of burner described by Kern in his Specification No. 294 Jan. 5th
1897 or we may use any good form of Bunsen or white flame gas-burner or a
suitable flame obtained by the combustion in a good burner of petroleum, spirit,
acetylene, or the like.
Fig. 1 shows our invention (in sectional elevation) as applied to a common form
of water heater in which the water is allowed to come in contact with the products
of combustion. The cold water enters at A and issues in the form of a jet along
the outlet pipe B. Its impetus being lost the water falls to the bottom of the
pipe B and runs back into the heater where its temperature is raised by its
coming in contact with the heated gases.
Fig. 2 shows our invention (in sectional elevation) as applied to an ordinary
coil form of water heater in which the water is not allowed to come in contact with
the products of combustion. In the apparatus illustrated the water passes along
a spiral tube or coil which is heated by the gas, oil, or spirit burners.
The cold water enters at A and fills (or it may be impinges upon) the buckets.
of the turbine B, causing it to revolve.
The spindle of the turbine passes through a stuffing box C, which prevents any
water from escaping into the outlet pipe, and is fitted with a bevel wheel D.
This wheel gears into another bevel wheel E, to the spindle of which is fixed
an exhausting fan F. The cold water after passing through the turbine causing
it, and consequently the fan F, to rotate, flows down the tube G, and into the
heater, where, passing through the spiral coil H it is raised in temperature and
passes out at the outlet I.
Fig. 3 shows a side elevation of the same heater but with the side of the
turbine removed.
Fig. 4 in elevation shows our invention attached to a flue elbow, which can be
socketed upon the flue nozzle of a heater.
Fig. 5 shows an adaptation of the Kern burner (Specification No. 294 Jan. 5th
1897) to the base of a gas water heater.
The jet shown in Fig. 1 may be single or consist of several apertures, and may
be fitted on any convenient part of the outlet flue. But we lay no claim to the
use of a jet or spray in the interior of the water heater, defining the words

page_text: outgoing products of combustion as referring exclusively to those products
which have left the heater proper and have entered into the outlet flue as shown in
the drawings.
We may couple the spindle of the turbine B, Figs. 2, 3, & 4, direct to that of the
fan when their relative positions and the speed required render this advisable or
we may use any form of gearing such as sprocket wheels and chains, or any train
of wheels.
We may obviously use the exhausting fan arrangement on a heater of the first
described species. The turbine may be over or under shot and may carry buckets
at its periphery or blades.
We also propose to use in connection with suitable forms of water heaters
the form of atmospheric burner described by Kern in his Specification No. 294
of 1897, as shown in Fig. 5.
Having now particularly described & ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is: -
66
(1) The use of an aspirating jet or an exhausting fan in the outlet flues of water
heaters or geysers," the jet being formed, & the fan worked by the water supplied
to the heater before such water has come in contact with the means provided for
heating it.
(2) The use in connection with water heaters of suitable construction of the
form of atmospheric burner described by Kern in his Specification No. 294 of 1897.
Dated this 7th day of April 1899.
