Complete Specification Left, 13th Apr., 1891-Accepted, 16th May, 1891
PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating Water by Steam.
We, WILLIAM MATTHEWS, JOSEPH YATES, and WALTER YATES, all of
Todd Street Manchester in the County of Lancaster, Gas and Ventilating
Engineers, do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for heating water by means of steam.
In an apparatus constructed according to these improvements the water is heated
in a calorifier or closed vessel into which steam is admitted, the steam, or preferably
the water, being contained in the calorifier within a coil, so that there is no actual
or direct contact between the water to be heated and the steam. From the
calorifier the water passes to a circulating cylinder which is also a closed vessel and
which is connected with the reserve tank or cistern.
The hot water may be withdrawn from the pipes leading from the calorifier to
the circulating cylinder, and the water resulting from the condensation of steam in
the calorifier may be caused to return to the boiler by gravity or when this is
inconvenient or impracticable, it may be withdrawn by means of a suitable steam
trap.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Heating Water by Steam.
We, WILLIAM MATTHEWS, JOSEPH YATES, and WALTER YATES, all of
Todd Street, Manchester, in the County of Lancaster, Gas and Ventilating
Engineers, 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 apparatus for heating water by means of steam.
In an apparatus constructed according to these improvements, the water is heated
in a calorifier or closed vessel into which steam is admitted, the steam, or preferably,
the water, being contained in the calorifier within a coil, so that there is no actual

calorifier the heated water passes to a circulating cylinder which is also a closed
Vessel and which is connected with the reserve tank or cistern.
The hot water may be withdrawn from the pipes leading from the calorifier to
the circulating cylinder, and the water resulting from the condensation of the
steam in the calorifier may be caused to return to the steam generator by gravity,
or when this is inconvenient or impracticable, it may be withdrawn by means of a
suitable steam trap.
We will describe in what manner we may carry our invention into practical
effect with reference to the accompanying drawing which represents an apparatus
constructed according to our improvements partly in section and partly in
elevation.
In the drawing, A is the calorifier which consists of a strong steam tight vessel con-
taining the coil B. Steam is admitted to the interior of the calorifier by suitable
pipes which it is not necessary to shew in the drawing. C is a steam trap of any
suitable construction by means of which the water arising from the condensation

page_text: of steam in the calorifier is removed. As already set forth, when the condensed
water can run back by gravity to the steam generator, the steam trap will not be
required. D is the circulating cylinder, K the reserve cistern, and E, F, G, H, the
pipes connecting the calorifier, circulating cylinder, and reserve cistern, and which
pipes are arranged in a similar manner to the corresponding pipes of an ordinary
water heating system in which a circulating cylinder is used.
The hot water may be withdrawn from the apparatus through taps I I in the
pipe E, or in a pipe leading from the reserve cistern.
J is a trough or sink for catching waste water.
If the water is to be heated in the calorifier by means of steam contained in the
coil, the pipes E and H instead of being connected with the ends of the coil B are
merely connected with the interior of the calorifier, the ends of the coil being con-
nected respectively with the steam inlet and condensed outlet pipes.
Having now particularly described and 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―
An apparatus for heating water constructed and arranged substantially as herein-
before described with reference to the accompanying drawings.
