HOT-WATER APPARATUS."

PROVISIONAL SPECIFICATION left by the said Walter Chapman Burder

IMPROVEMENTS IN BOILERS FOR HOT-WATER APPARATUS."
My improved boiler may be made of cast or wrought iron, and consists of a
water chamber in the form of a saddle closed at its upper end, or the said water-
chamber may be made of any other suitable shape. The front of the boiler, which
forms also the furnace front, may be hollow and form part of the water chamber, or
may be made of a solid plate. The said front is secured to the boiler by bolts and
nuts, india-rubber or other suitable washers being inserted between the said front
and the other portion of the boiler to ensure a tight joint. When the said front is
bollow, communication is obtained by means of two or more holes in each part,
through which the water circulates. The fire-box or chamber is thus enclosed on
all sides by a water space or chamber. The said front is provided with openings
for the feed-door, ash-pit door, and cleaning door, and an opening is also formed
either through the said front or other convenient portion of the boiler for fixing a
smoke-flue or chimney. Sockets are cast or fixed upon the boiler in convenient
positions for connecting the hot water pipes.
The advantages of this boiler are that it may be fixed inside a greenhouse or
other building without danger of fumes or smoke escaping, as although the boiler
is inside the building the furnace front is outside, and all stoking is done from the
outside. A great saving is also effected as the heat from the boiler is utilized
instead of being wasted, as is the case with all other forms of boilers.

My improved boiler may be made of wrought or cast iron, and consists of a
water chamber A in the form of a saddle closed at its upper end, or the said water
chamber may be made of any other suitable shape. The front B of the said boiler,
which forms also the furnace front, may be hollow and form part of the water
chamber, or it may be made of a solid plate. The said front B is secured to the
boiler by bolts and nuts. When the said front is hollow communication between
the said front and other portion of the boiler is obtained by means of two or more
holes in cach part through which the water circulates, india-rubber or other
suitable washers being inserted between the said front and the other portion of the
boiler to ensure a tight joint. The fire-box or chamber C is thus enclosed on all
sides by the water-space or chamber A. The said front B is provided with
openings for the feed-door D, ash-pit door E, and cleaning door F, and an opening
is also formed either through the said front or other convenient portion of the
boiler for fixing a smoke-flue or chimney G. Sockets H are cast or fixed upon the
boiler in convenient positions for connecting the hot-water pipes; I are the fire
bars, and J is the baffle plate.
The advantages of this boiler are that it may be fixed inside a greenhouse or
other building without danger of fumes or smoke escaping, as although the boiler
is inside the building, the furnace front is outside, and all stoking is done from the
out-ide.
A great saving is also effected, as the heat from the boiler is utilized
instead of being wasted, as is the case with all other forms of boilers.
Having thus fully described my said Invention and shown how the same may be
conveniently and advantageously carried into practice, I claim,―
The improved boiler for hot-water apparatus, constructed substantially as herein
described and illustrated by the accompanying Drawing.
In witness whereof, I, the said Walter Chapman Burder, have hereunto set
my hand and seal, this First day of June, in the year of our Lord 'One
thousand eight hundred and eighty two.
WALTER CHAPMAN BURDER. (L.B.)
