Improvements in Boilers for Hot Water Circulation, also for
Kitchen Ranges and Laundries.

SAMUEL WILSON Riversley Rothsay Road Bedford, Gentleman, do hereby
declare the nature of this invention to be as follows:-
My invention relates to boilers both for high and low pressure for general
warming or heating by means of hot water circulation, also for heating water for
domestic and other purposes. The object of my invention is to get more heating
surface on the boiler, whether made of cast or wrought metal, so as to get better
results than heretofore in more rapid generation of heat, greater economy in fuel,
and in making the boilers durable. The boilers can be made any shape, but I
propose to use rectangled ones, and by preference I place them in casings made of
metal or other fireproof material and so arranged that the heat can circulate all, or
nearly all, over the surface of the boiler, before it escapes into the chimney. If it
is found desirable to get more heating surface on the boiler, whether in a casing or
otherwise, I propose, in the case of cast boilers, to cast ribs on the face of the
boiler in the part or parts of the surface and in such number, dépth, or thickness
as thought most desirable. When the boiler is made of wrought metal, these ribs,
if not worked, dovetailed, or welded on, can be secured to the face by means of
bolts, screws, or pins.
I also propose to apply the same principle to stoves for heating or hot water
circulation, by placing the boiler in a metal or other fire-proof casing, & on the
top of it or in connection with it, to place a radiating cistern or tank, tubes, or
circulating pipes.
In these stoves I propose by préference to raise the fire so as to get in a back
flue plate with an adjustable door under the fire to clean out the flue under the
boiler as in the case of my pateut grate 13078,-/93. This door I so arrange that
hot air can be admitted into the flue in such a way that it will stimulate the
draught and help to consume the smoke by mixing with the products of
combustion.

I, SAMUEL WILSON of Riversley Rothsay Road, Bedford, in the County of
Bedford, Gentleman, do hereby declare the nature of this invention and in what
manner the
the same is to be performed, to be particularly described and ascertained
in and by the following statement:
My invention relates to boilers both high and low pressure for general warming
or heating by means of hot water circulation, also for heating water for domestic
and other purposes. The object of my invention is to get more heating surface on
the boilers whether made of cast or wrought metal so as to get better results than

making the boilers more durable.
The boilers can be made any shape, but I propose to use rectangular ones, and
by preference I place them in casings made of metal or other fireproof substance
and so arranged that the heat can circulate all, or nearly all over the surface of
the boiler, before it escapes into the chimney. If it is found desirable to get more
heating surface on the boiler whether in a casing or otherwise I propose in the
case of cast boilers to cast ribs on the surface on the part or parts, and in such
number, depth or thickness as thought most desirable. When the boiler is made of
wrought metal these ribs if not worked, dovetailed, or welded on can be secured to
the surface by means of bolts, screws, or pins. I also propose to apply the same
principle to stoves for heating or hot water circulation, by placing the boiler in a
metal or other fire proof casing on the top of it to place a radiating cistern, tubes
or circulating pipes. In these stoves I propose by preference to raise the fire so
as to get in a back flue plate with an adjustable door under the fire for cleaning
out the flue under the boiler as in the case of my patent grate No. 13078, 1893.
This door I so arrange that hot air can be admitted into the flue in such a way
that it will stimulate the draught and help to consume the smoke by mixing with
the products of combustion.
The fire for heating these stoves I propose shall be a close one where the air for
combustion can only enter the fire through the bottom or grate. This bottom or
grate can be placed above, on the level, or below the bottom of the boiler as found
most advantageous but so as to get in the flue plate as before described, and on
which the back of the bottom or grate shall rest, the flue plate and bottom to be
placed a distance from the face of the boiler so that a little of the fire will drop.
down behind it, and in front of the boiler.
To heat the air before entering the fire to increase combustion 1 form the bottom
or grate of thin taper bars from a quarter to half an inch thick at the top and
tapered almost to a point at the bottom, these bars to be from one inch to two
inches deep according to the size of the fire so as to heat and admit as much air as
possible into the bottom of the fire. A portion of this hot air I admit into the
boiler flue at an opening at the top of the adjustable door and also at the back of
the bottom or grate which is so constructed that the air will pass over it and mix
with the flame or fire at the entrance of the boiler flue thereby consuming the coal
and smoke that fall down into the flue consequently intensifying the heat under the
boiler.
The accompanying drawings will further describe my invention.
Fig. No. I is a rectangular boiler in position in a metal casing.
Fig. No. II is the top and front plates of the casing as I propose to make it, but
if desired the side plates can alone be used and in the case of kitchen ranges the
top or hot plate will form the cover or top of the casing.
Fig. No. III is a rectangular boiler with the ribs secured to the side and ends,
these ribs can be connected together with one or more cross plates and cast
altogether, or if made of wrought metal can be secured to the cross plate or plates
first and then these plates can be screwed or otherwise fastened to the surface of
the side, end, or bottom of the boiler as desired so that the ribs come in contact
with the boiler to convey the heat to it. In cast boilers the ribs will be cast on
the boiler.
Fig. No. IV is a section of a boiler with the ribs on the ends and bottom.
Fig. No. V, is a section of the stove showing a ribbed boiler A in a metal
casing C.
D shows the close fire in front of the boiler. E the bottom or grate. F, is the
flue plate with the adjustable door in it which is placed at a little distance from
the front of the boiler with the bottom or grate resting on it at the back.
G. G. are the doors that close in the front of the bars and the opening to clean out
the fire when required. H, is the door over the opening where the fire is supplied
with fuel. This stove can be raised or supported on brickwork, on legs, or placed

page_text: on the floor as required. The pipes connecting the flow and return to the boiler
can be put in the boiler where desired. Over, or round, or close to the casing can
be placed a cistern, hot water tank or radiators connected with the boiler for
heating purposes for halls, rooms, conservatories &c., or if used for public or other
buildings the heated water can be conveyed where required in pipes.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. The fixing or placing of boilers for kitchen ranges, laundries, & hot water
circulation in a casing of metal or other fireproof substance so as to heat the
whole, or most of, the surface of the boiler substantially in the manner and for the
purpose herein-before described.
2. The casting or placing of ribs or corrugations on the surface of the boiler so
as to increase the heating surface substantially and in the manner herein-before
described.
3. The construction of stoves with plain or ribbed boilers in a casing or
otherwise with a close fire in the manner and for the purpose herein-before
described.
