PROVISIONAL SPECIFICATION.
Improvements in and relating to Hot Water Boilers.
I, BENJAMIN FOWELL, Hot Water. Pipe Fitter, Romiley, Cheshire do hereby
declare the nature of my said invention to be as follows:-
My improvements relate to boilers for supplying hot water to the pipes of
horticultural and other buildings.
In accordance with my invention the boiler is fitted with the usual grate and
lined with fire brick and is supplied with fuel by preference through an aperture
through the top.
In the centre of the furnace and arranged vertically is a tube or pipe the ends of
which pass out at the top and bottom through the shell of the boiler and are each
provided with flanges or couplings to effect the connection with the hot water
pipes.
The tube or pipe is made interchangeable so as to agree with the size of the hot
water pipes. By so disposing the vertical tube or pipe a constant and uniform
flow of water is obtained at a considerable less cost than heretofore.
To prevent the tube burning out it may be surrounded with fire clay.

COMPLETE SPECIFICATION.
Improvements in and relating to Hot Water Boilers.
I, BENJAMIN FOWELL Hot Water Pipe Fitter, Romiley Cheshire, do hereby
declare the nature of my said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention consists of an improved boiler for supplying hot water to the hot
water pipes or other heating apparatus of horticultural and other buildings.
On the accompanying drawing
Fig. 1 is a front view of my improved hot water boiler and Figs. 2 and 3
transverse sectional views respectively.
In accordance with my invention the boiler consists of a pipe of large area or,
by preference, a pair of small pipes A, A which are situated in a furnace B as
illustrated, and are in communication with the hot water heating apparatus
aforesaid, being provided with flanged extremities C to make the necessary
connections thereto.
The upper ends of the pipes A extend through the side or, by preference, the
top of the furnace, and the lower extremities through the grate into the ash pit &
to the outside through the plate D as illustrated.
The furnace B is provided with a fire brick lining E encased in the metal sides
and ends F which are held together by the angle or corner pieces G, and said
furnace is fitted with the grate or fire bars H which is or are formed to allow room
for the pipes A to pass through.
The tubes or pipes A are made up of the several parts shewn in transverse
section Fig. 4 which are held together by the socket connections H' and by means
of the rods and bolts I. The furnace is provided with a door J through which
the fuel is supplied and also with a door or set of sliding doors K for removing the
ashes from beneath the fire grate. L is the flue for the escape of smoke.

page_text: A boiler made up and constructed in the manner aforesaid will give a constant
and uniform flow of hot water throughout the system of hot water pipes or other
heating apparatus at a considerable less cost than heretofore.
Three tubes may be employed as shewn in Fig. 5 braced or grouped together as
illustrated, the several members being secured by the vertical rods 1 (shewn dotted)
and the transverse bar or rod M, which latter rests upon the bend or breech of
each of the vertical pipes.
The pipes are made interchangeable so that they may agree with the size of the
hot water pipes to which they are to be joined. In order to remove the pipes for
this purpose the pipes are uncoupled at C, and the top and side or back of the
furnace and the fire bars are removed allowing the pipes to be drawn out and
permitting the new pipes to be placed in position.
The fire bars are made independent of each other so that any one may be shaken
to clear the fire, the front extremities of said bars extending some distance beyond
the front face of the boiler for this purpose (see Fig. 3).
The pipes or tubes A, A may be surrounded with fire clay to prevent them
burning out.
Having thus 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 :-
.
1st. A hot water boiler consisting of metal pipes or tubes A, A, placed in a
furnace B, with their upper extremities passing, by preference, through the roof
of said furnace with their lower extremities passing through the special fire
grate H, and both of said extremities terminating in suitable connections for
connecting them to hot water heating apparatus substantially as hereinbefore
described and illustrated on the accompanying drawing.
2nd. The general construction and arrangement of parts constituting my
improved hot water boiler substantially as set forth and illustrated.
Dated this 7th day of April 1893.
