Improvements in Water Heating and Circulating Apparatus.
I, WILLIAM MAYCOCK, of 2 Burnham Terrace, Clarence Street, Southend-on-
Sea, in the County of Essex, Plumber, 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 has reference to the improved construction hereinafter described.
with reference to the accompanying illustrative drawings of water heating and
circulating apparatus of the kind in which water is heated in a boiler by means
of a lamp and is caused to circulate by a suitable arrangement of pipes.
Figs. 1 and 2 shew respectively a central longitudinal section and a cross section
of my improved heating and circulating apparatus with oil lamp in elevation.
Fig. 3 is a plan; and
Fig. 4 a horizontal section on the line A A of Fig. 1, the upper section of the
boiler being removed.
The boiler, which is constructed of suitable material that is a good conductor
of heat, for example copper, is formed in two connected main sections or parts
arranged one above the other at a short distance apart, the lower section 1 being
constructed with short fire-tubes 2 through which some of the flame and products
of combustion from the lamp pass into the space 3 between the two sections,
some passing also up the sides of the lower section; the flame and products.
travel over the surface of the upper section 1ª to a suitable chimney 4.
This boiler is supported on a stand or stove 5, the lower portion of which is of
cast iron and so forined that air is readily admitted to the lamp which is arranged
within said stand or stove and the upper part of which is of sheet metal and forms
an enclosing wall around the flame. The lamp may be of any suitable construction,.
and may have any desired number of burners or wicks there being three in the
example shown. The boiler is enclosed in a sheet metal casing 7 which is open
at the bottom and is supported at 7" upon the stand 5 as shewn in Fig. 2. The
casing projects downwardly to somewhat below the level of the wicks of the
lamp, and carries the chimney. The two sections of the boiler are connected as
follows:-8 is a nipple; it is screwed into correspondingly screw-threaded tubular
bosses 8 8b suitably secured to the upper and lower sections respectively of the
boiler.
9 is the outlet from the top of the upper section of the boiler to the circulating
pipe 9 and 10 is the inlet from the said circulating pipe to the lower section of
the boiler. The latter section is formed with a downwardly projecting portion 1b.
arranged outside the stand 5 and in which the inlet 10 is formed, so that
the cooler water will always enter the boiler at the lower part thereof. Thus the
circulation of the water through the boiler is facilitated.
The casing 7 is formed with inwardly projecting side and end partitions 11
and 11 respectively. The partitions 11 extend almost to the sides of the upper
section of the boiler, and to their inner edges are attached corrugated deflecting
plates 12, which extend the full length of the boiler so that a narrow passage is
formed between the sides of the upper section of the boiler and the said deflecting
plates. Between the said deflecting plates and the casing the partitions 11 are
formed with slots 13. The partitions 11ª extend slightly beneath the ends of the
upper section of the boiler so as to carry the same, and are formed with per-
forations 14. The partitions 11 & 11ª rest upon the stand or stove 5 and thus
support the casing 7.
When the lamp is alight, the flames therefrom impinge upon the bottom of the
lower section of the boiler and the hot gases and products of combustion pass, as

page_text: indicated by the arrows through the fire-tubes 2 into the space 3 between the
upper and lower sections, and also around the sides of the lower section, and thence
flow through the passages between the deflecting plates and the sides of the upper
section, finally escaping along the top of this section to the chimney.
Small portions of the products of combustion pass out from the ends of the space
between the upper and lower sections 1ª and 1 of the boiler at points below the
partitions 11 and pass through the perforations 14 on their way to the chimney.
The current of air which, (when the lamp is alight) will be drawn by the chimney
draught upwardly through the lower part of the casing 7, the slots 13 and
perforations 14 and the upper part of the casing, will carry away through the
chimney any unpleasant gases or vapours that may be given off by the lamp.
The circulation of the water through the boiler is indicated by dotted arrows in
Fig. and will be readily understood on reference thereto.
15, 15 are sight holes glazed with talc or mica in the stand 5 and casing 7
respectively and through which the lamp flames may be inspected. 16 is a tightly
fitting door in the upper part of the casing 7 for facilitating the fixing of the
upper section 1ª of the boiler.
As will be evident the details of construction might be modified; thus, there
might be more than one lower section such as I have described, and there might
be more than one lamp.
Apparatus constructed according to this invention is adapted for heating water.
and causing circulation thereof through a coil or coils of pipes for heating green-
houses, offices, and other purposes, also for heating and causing the circulation
of water through pipes connecting the boiler or boilers with a hot water reservoir
or reservoirs for supplying baths, lavatories, and the like.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a water heating and circulating apparatus of the kind herein referred to,
the improved construction of boiler comprising sections such as 1 and 1ª relatively
arranged and connected together substantially in the manner hereinabove described
and illustrated.
2. In a water heating and circulating apparatus of the kind mentioned, the
combination of a boiler such as referred to in the preceding claim with an enclosing
casing constructed and arranged substantially as described.
3. Water heating and circulating apparatus constructed and arranged as shewn
in and described with reference to the accompanying drawings.
Dated this 25th day of August 1893.
