PROVISIONAL DIECIFICATION.
Improvements in the Construction and Manufacture of Hot Water
Boilers.
I, BENJAMIN GREENWOOD SMITH, of Stannary Street, Halifax, in the County
of York, Brass and Iron Founder, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the construction and manufacture
of hot water boilers for domestic purposes the object being to construct à boiler
having a large heating surface and one which can readily and quickly be scaled "
and cleaned inside by removal of incrustation. Boilers constructed as hereinafter
described combine the advantages of boilers or heaters having a coil or coils of
pipes but obviate the objection that the interior of a coil cannot be cleaned.
The invention consists of a boiler constructed of a series of tubes or pipes placed
at angles to and connecting with one another and provided with hand holes or
plugs at points from which the interior can be cleaned.
According to this invention the boiler is made of a series of pipes or tubes one
series being placed parallel to one another and the other preferably at right
angles thereto, the whole constituting a boiler or heater made of a series of pipes
or tubes which present a great amount of surface to the fire or heating agency.
At or near the point of intersection of one pipe with another I place a screw plug
or cap which can readily be removed and the interior of the adjacent portions of
the tube or tubes cleaned. The improved boilers may be made of copper, brass,
iron, or a combination of these, and may be cast in one piece or made in several
parts brazed or welded together.

COMPLETE SPECIFICATION.
Improvements in the Construction and Manufacture of Hot Water
Boilers.
I, BENJAMIN GREENWOOD SMITH, of Stannary Street, Halifax, in the County
of York, Brass and 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:—
This invention relates to improvements in the construction and manufacture
of hot water boilers for domestic purposes the object being to construct a boiler

page_text: ..
having a large heating surface and one which can readily and quickly be scaled
and cleaned inside by removal of incrustation or sediment.
Boilers constructed as hereinafter described combine the advantages of boilers
or heaters having a coil or coils of pipes but obviate the objection that the interior
of a coil cannot be cleaned..
The invention consists of a boiler constructed of a series of tubes or pipes placed
at angles to and connected with one another and provided with hand holes or
plugs at points from which the interior can be cleaned. The boiler when in
position is preferably covered with a perforated guard plate or shield.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the annexed drawings, in
which:-
Fig. 1 is a front view of the improved boiler.
Fig. 2 is a side view of the boiler in position in a grate.
Fig. 3 is a view of a shield or cover for preventing the boiler tubes from being
covered with ashes.
According to this invention the boiler is made of series of pipes or tubes, one
series 1 being placed parallel to one another and the other 1^ preferably at right
angles thereto, the whole constituting a boiler or heater made of a series of
pipes or tubes which present a great amount of surface to the fire or heating
agency. At or near the point of intersection of one pipe with another I place a
screw plug or cap 2 which can readily be removed and the interior of the adjacent
portions of the tube or tubes scraped and cleaned.
The upright tubes 1* of the boiler are supported in brackets 3 (only one of which
is shewn) limed or fixed into the brickwork 4. The upright tubes may have
projections 4 cast on them for keeping the boiler off the brickwork 4 and thereby
allowing any flames or products of combustion to wrap round the boiler. The
boiler is covered up by a perforated shield or cover 5 (shewn in section in Fig. 2
and front elevation in Fig. 3) to prevent as far as possible ashes or dirt from
clogging up the boiler tubes, and at the same time to allow the flames and heat
to pass through the perforations 7. The shield or cover 5 can be readily removed
for cleaning the boiler, as it simply rests in a nick or groove 8 in the brackets 3,
and the upper edges rest against the brickwork 4. At 6, 6 are inlet and outlet
pipes connected with the boiler and both at the top or upper portion of same.
The improved boiler is cast in iron, copper, or other metal, and in one piece,
and the plug holes then tapped for the reception of the plugs or caps 2, and
when it is desired to clean the interior of the boiler it is only necessary to remove
the plugs or caps 2 and all parts of the interior can be easily cleaned and if
necessary scraped.
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
(1) The improved boiler or water heater as herein described and substantially
as illustrated by Figs. 1 and 2 of the accompanying drawings.
(2) A boiler consisting of a series of tubes or pipes parallel to one another and
connected by tubes or pipes at an angle thereto, each tube or pipe having an
independent screw or plug inlet by which its interior may be cleaned, as herein
described and substantially as illustrated by Fig. 1 of the annexed drawings.
