I CHARLES DAMON YATES of 24 Tunstall Road, Brixton in the County of
Surrey Engineer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN APPARATUS FOR SUPPLYING STEAM AND HOT WATER FOR COOKING AND
OTHER PURPOSES," to be as follows:-
My Improvements consist of a feed cistern and boiler.
In carrying out my invention I proceed in the following manner :-
The cistern consists of an Iron or other Metal case made of any suitable shape
to contain water, in which there are two chambers (in addition to the main body
or principal compartment of the cistern) in the interior of the Main Iron Case.
The larger one of the two chambers is a receiver of cold water which is supplied
from the main, passing through a back pressure Ball-valve to resist any back
pressure from steam forming in the after named boiler. The smaller chamber of
the two is formed by a partition fitted direct over the outlet hole from the cistern
to the boiler, and constitutes with the side of the cistern a box of oblong shape
from the top of the outlet hole to nearly the bottom of the cistern covering the
outlet hole and leaving a passage of say about three inches by about one inch
debouching to the bottom of the principal compartment of the cistern. This
smaller chamber also forms a check of any back pressure of water or steam.
Upon the top of the outside case is fixed a safety Lever valve and weight having
a passage in connection with the feed cistern and through it with the boiler, in
both of which there is an equal pressure of steam, the lever-valve forming a safe-
guard against any other pressure of steam generated in the boiler and cistern
combined.
The boiler consists of two circulating chambers, one or more steam chests and a
coil or coils of pipe or piping. The water passes through the outlet from the cistern
into the bottom chamber which is of an annular or tubular but truncated conical
form having an opening through its centre for the passage of the heated air and
an annular V shaped recess extending up from the bottom of the chamber so
that the annular or tubular water space assumes a ☐ section. The heated air
in addition to ascending through the central passage also penetrates into the
V shaped recess so as to act through its walls on the centre of the flowing

page_text: water, which passing from the chamber through a coil or coils, tube or tubing
of any suitable shape, enters the upper chamber preferably of a truncated conical
form and having a bottom by preference of a dome or other equivalent shape.
This chamber also has a central opening through which the heated air passes, and
impinges upon its walls and also upon a steam chest above, from which I insert a
pipe or pipes making a connection into the main body or principal compartment of
the feed cistern, so that the steam passes from the Boiler into the feed cistern,
thus giving an equal pressure of steam in the feed cistern as in boiler as above
described. The boiler is plentifully supplied with water for the generation of
steam without the aid of an injecting pump or use of float stone.
The above Boiler is incased in an Iron (or other) jacket and is heated either
by Gas Oil or Fuel.

I CHARLES DAMON YATES of 24 Tunstall Road, Brixton in the County of
Surrey, Engineer, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN APPARATUS FOR SUPPLYING STEAM AND HOT WATER FOR COOKING AND
OTHER PURPOSES" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
My Invention relates to Apparatus for supplying in an economical and expe-
ditious manner, steam and hot water for cooking and other purposes, among which
purposes is included the use of steam as a motive fluid; and the Invention consists
in the combination with a steam generator or boiler of a feed cistern consisting of
a cold water receiver, the supply to which is regulated by a back pressure ball
valve, a main compartment with which the cold water receiver communicates and
a chamber partitioned off from the main compartment and containing the outlet
to the steam generator or boiler; also in a steam generator consisting of two
circulating chambers connected by coils and of one or more steam chests, the whole
constructed and arranged substantially in the manner hereinafter described.
And in order that the said Invention may be perfectly understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the two figures on the accompanying sheet of drawings, the same letters of reference
indicating corresponding parts in both the figures.
Figure 1 of the accompanying drawings represents a sectional elevation of a feed
cistern and steam generator or boiler constructed and arranged according to my
said Invention and Figure 2 is a sectional plan of the same corresponding to
Figure 1.
A is the cistern consisting of the cold water receiver a the main compartment b
and the chamber c.
The
The cold water receiver a is supplied from the main, the water entering through
a back pressure Ball-valve d to resist any back pressure from steam forming in
the boiler B to which the main compartment b is connected, the cold water receiver a
being in communication with the main compartment 6 through openings e e.
chamber c is formed by a partition f fitted directly over the outlet hole g from the
cistern A to the water space of the boiler B and constitutes with the side of
the cistern a box of oblong shape from above the top of the outlet hole to nearly
the bottom of the cistern covering the outlet hole and leaving a narrow passage
debouching at h to the bottom of the cistern. This chamber c also forms a check
of any back pressure of water or steam. Upon the top of the outside case i of the
cistern is fixed a safety Lever Valve and weight k, the said valve having a passage
in connection with the feed cistern from which is a pipe m leading to the steam
space of the boiler, so that there is an equal pressure of steam in the feed cistern
and boiler, the lever valve k forming a safe-guard against any other pressure of
steam generated in the boiler and cistern combined.

page_text: The boiler consists of two circulating chambers no, one or more steam chests p,
and a coil or coils q of piping. The water passes through the outlet and pipe g
from the cistern into the bottom chamber n which is of an annular or tubular but
truncated conical form having an opening through its centre for the passage of
the heated air from the furnace or burner C and an annular V shaped recess 8
extending up from the bottom of the chamber. The heated air in addition to
ascending through the central passager also penetrates into the ✓ shaped recess 8
so as to act through its walls on the centre of the flowing water which passes
through the chamber n and from such chamber through the coils q to the upper
chamber o. This chamber, which may be of a truncated conical form with a concave
bottom, also has a central opening u through which the heated air passes and
impinges upon its walls and also upon the steam chest p above, with which the
'chamber o communicates through openings t.
From the steam chest extends
the pipe m leading to the cistern, so that the steam passes from the Boiler into
the feed cistern thus giving an equal pressure of steam in the feed cistern and
boiler as above described.
By the arrangement of cistern described the boiler is plentifully supplied with
water for the generation of steam without the aid of an injecting pump or use of
float stone.
A supply of water raised to an elevated temperature may be drawn off for any
required purpose from any convenient point of the apparatus as for example at U
and the steam generated may be delivered from the steam chest p through a pipe
or connection wor it may be taken from the top of the cistern or from the pipe m
if desired.
The boiler is enclosed in a casing x and is heated either by gas, oil or solid fuel
a gas burner C being shewn in the example illustrated.
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
1st The combination, with a steam generator or boiler, of the feed cistern, con-
sisting of the cold water receiver a, the main compartment b, and the chamber c,
all constructed, connected and arranged substantially as and for the purpose herein-
before described.
2nd A. steam generator or boiler, consisting of two circulating chambers connected
by coils, and of one or more steam chests, the whole constructed and arranged
substantially as and for the purpose hereinbefore described.
