IMPROVEMENTS IN WATER HEATING APPARATUS
Year: 1885

page_text: We, JOSEPH SHELDON STUBBS, and SHELDON HAROLD STUBBS, both of Long-
sight, Manchester, Engineers, do hereby declare the nature of our invention for
"IMPROVEMENTS IN WATER HEATING APPARATUS," to be as follows:-
The improvements relate to water heating apparatus for use in various
manufacturing purposes, public baths, hotels, steam laundries, the providing of
hot water for work people's tea, or other beverage, and similar requirements; and
have for object the providing of such heated water free of rust, sediment, or other
impurity either in large or small quantities, without cisterns or like causes of
detriment to the water.
To accomplish this and to effect our improvements, we construct
coil of copper,
galvanized iron, or other metal not subject to much corrosion, which is fitted in the
steam space of any suitable steam boiler. This coil (or it may be coils) is connected
at each end thereof to suitable pipes passing through the boiler plates, one of
which is joined up to the cold water supply, and the other to a receiver fixed
outside the boiler, and which may be placed at any desirable point.
This receiver is thereby always filled with water, and thus condenses any steam
which may have been generated in the coil or coils inside the boiler, and is fitted
with a suitable tap, or taps, for delivering the hot water as required.
The receiver is also connected with the cold water service by means of a valve
or tap for the purpose, so that the temperature of the water before drawing may
be lowered if requisite and so rendered suitable for use; to facilitate which a
thermometer may be added to the receiver in any suitable manner,

We, JOSEPH SHELDON STUBBS, and SHELDON HAROLD STUBBS, both of Long-
sight, Manchester, Engineers, do hereby declare the nature of our invention for
"IMPROVEMENTS IN WATER HEATING APPARATUS," 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 water heating apparatus for use in various
manufacturing purposes, public baths, hotels, steam laundries, the providing of
hot water for work people's tea or other beverage, and similar requirements; and
have for object the providing of such heated water free of rust, sediment, or other
impurity, either in large or small quantities, without cisterns or like causes of 1
detriment to the water.
To accomplish this and to effect our improvements, we construct a coil or system
of pipes composed of copper, galvanized iron, or other metal not subject to much
corrosion, which is fitted in the steam or water space, or both, of any suitable steam
boiler. This coil or system (or it may be coils or systems) is connected, at each end 1
thereof, to suitable pipes passing through the boiler plates, one of which is joined
up to the cold water supply, and the other to a receiver fixed in any convenient
position outside the boiler. This receiver is thereby always filled with water and
thus condenses any steam which may have been generated in the coil or system of
pipes inside the boiler, and is fitted with a suitable tap, or taps, for delivering the a
hot water as required. The receiver is also connected with the cold water service by
means of a valve or tap for the purpose, so that the temperature of the water, before
drawing, may be lowered if requisite and so rendered suitable for use; to facilitate
which a thermometer may be added to the receiver in any suitable manner.
But that the improvements may be better understood, we will by the aid of the
accompanying drawings proceed more fully to describe means employed by us.
DESCRIPTION OF Drawings.
Figure. 1. represents a longitudinal elevation, partly in section, of one form of
boiler fitted with the internal portions chiefly of apparatus in accordance with our
invention; and Figure. 2. a front elevation of such boiler with the apparatus
attached, chiefly the external portion.
The same letters indicate corresponding parts wherever they occur.
a, a, is the
boiler, and b b the coil or system of pipes within, which may be in the steam space
as shewn, or in the water space or both. cc is the inlet for cold water, and d d
the outlet from the boiler for the hot water to pass to the receiver. This d d is
connected with the receiver e e, a hollow vessel of any suitable form and size, which
has the cold water supply also attached at ff, for the purpose of letting down the
water to the requisite temperature, for which purpose the thermometer g g may be
attached. From the receiver e the delivery pipes may convey the water to any
convenient point with tap or taps attached.
Variations in detail may be made, such as the length and form of the coil or
avstem of nines within the boiler. the nosition and form of the receives outside the
4

without departing from the peculiar character of the invention.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
The employment of a coil or system of pipes, or more than one, within a steam
boiler, attached to and in combination with a receiver vessel outside, for the
purpose of supplying hot water, for the uses, and in manner, substantially as shewn
and described.
