PROVISIONAL SPECIFICATION.
An Improved Hot Water Boiler for Heating Greenhouses, Vineries,
Conservatories, and other Buildings.
I WILLIAM STUTTLE of 13 Butler Street Greenheys Manchester in the County of
Lancaster Iron founder do hereby declare the nature of this invention to be as
follows:-
I make my improved boiler of an upright cylindrical form externally, and formed
of copper, having a cast iron base. Inside the external copper cylinder is an internal
cone (also of copper) tapering upwards and the cavity between the copper cylinder
and cone forms the water space, the two being joined together at top and bottom by
a ring.
The inside of the cone forms the fire place, a cast iron grid being placed at the
bottom and at the upper end (which is open) I have a cast iron ring to which I fix an
extended feeding tube to contain a supply of fuel.
To the outside of the copper cone, and in the water space I fix a number of
radiating plates of copper which serve to conduct and radiate the heat so as to obtain
an increased heating surface.
The chimney or flue is taken from the fire place through the boiler near to the
bottom so as only to leave such a depth at the bottom as may be required for the fire
and not to burn the fuel above. This flue is enclosed in a water casing in connection
with the boiler so as to prevent loss of heat, and it may be fitted with cross pipes and
radiation plates if required.
Across the front of this flue two small upright tubes are fitted to prevent the fuel
from entering the flue, and the cast iron base is fitted with a fire door and ventilator.
The top of the extended feed tube is provided with a cover and a cast iron or sheet
iron continuation of the flue forms a chimney, or leads to a chimney as the case
may be.

I WILLIAM STUTTLE of 13 Butler Street Greenheys Manchester in the County of
Lancaster Iron Founder 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 :-
The objects of my invention are to economize the cost of the manufacture of hot
water boilers used for heating purposes and to increase or improve their heating
qualities.
The nature of my invention and the manner in which the same is to be carried into
practical effect will be readily understood on reference to the annexed sheet of
drawings and the following explanation thereof.
Fig. 1. is a vertical section through the improved boiler and flue. Fig. 2 a
horizontal section of the same and Fig. 3. a front elevation.
I make my improved boiler of an upright cylindrical form externally as shown
at a, a and formed of copper having a cast iron base b, b. Inside the external copper
cylinder a, a is an internal cone c, c (also of copper) tapering upwards and the
cavity d, d between the copper cylinder a, a and cone c, c forms the water space the
two being joined together at top and bottom by rings e, e and f, f.
I may here remark that (if preferred) the cylinder a, a and cone e, e may be made
of plate iron or mild steel.
The inside of the cone c, c forms the fire place, a cast iron grid g, 9 being placed at
the bottom and at the upper end (which is open) I have a cast iron ring e, e to which
I fix an extended feeding tube h, h to contain a supply of fuel.
To the outside of the copper cone c, c and in the water space I fix a number of
radiating plates i, i of copper which serve to conduct and radiate the heat so as to
obtain an increased heating surface.
The chimney or flue k, k is taken from the fire place through the boiler near to the
bottom so as only to leave such a depth at the bottom as may be required for the fire
and not to burn the fuel above.
This flue k, k is enclosed in a water casing 1, 1 in connection with the boiler, so as to
prevent loss of heat, and it may be fitted with cross pipes m, m and radiation plates n, n
if required.
Across the front of this flue k, k two small upright tubes o, o are fitted to prevent
the fuel from entering the flue k, k and the cast iron base b, 6 is fitted with an ash pit
door and ventilator.
The top of the extended feed tube h h is provided with a cover p, p, and a cast iron
or sheet iron continuation of the flue k, k forms a chimney or leads to a chimney as
the case may be. 9, 9 is the flow pipe and r,r the return pipe for the circulation of
the hot water.

page_text: This pipe is made with a forked branch **, ** extending about three parts round
the boiler and communicating therewith by a number of small holes.
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 :-
First. The radiating or heat conducting plates i, i round the body of the boiler.
Secondly. The water tubes o, o at the mouth of the flue next the fire to prevent the
fuel from falling into the flue.
Thirdly. Attaching the flue or chimney near to the bottom of the boiler (instead of
at the top) so as to confine the combustion to the bottom layer of the fuel.
Fourthly. Encasing the lower end of the flue or chimney with water and providing
the same with radiating plates n, n and cross tubes m, m to economize the waste heat
of the flue.
Fifthly. Fitting or forming the return water pipe with a forked branch extending
about three parts round the boiler and communicating therewith by a number of
small holes, all being constructed substantially as and for the purposes herein before
set forth and illustrated by the drawings annexed.
