PROVISIONAL SPECIFICATION.
Improvements in the Method of and Means for Heating and
Circulating Water.
We, WILLIAM HENRY BUSHELL, Managing Director of the Tubular Bath Boiler
Company Limited, of 184, Gray's Inn Road, in the County of London, and THE
TUBULAR BATH BOILER COMPANY LIMITED, as aforesaid, do hereby declare the nature
of this invention to be as follows:-
In hot water circulating systems as heretofore constructed and arranged the water
flows from the ordinary cistern into a hot water tank which is connected by circulating
flow and return pipes with the boiler. The water is heated in its passage through
the boiler and is drawn off from an expansion pipe connected to the upper part of the
hot water tank, or off the hot water flow pipe from boiler. Although this system is
otherwise well adapted for heating and circulating water, after a time the interior
of the boiler and the circulating pipes become choked with the sediment or furry
deposit resulting from the precipitation of the lime or other solid particles contained
in the water which is constantly circulating through them.
The object of this invention is to construct and arrange water heating and
circulating apparatus so as to prevent the furring of the boiler and circulation
pipes.
This object we accomplish by so arranging the apparatus that the water from the
cistern flows into the hot water tank where it is heated by a coil connected by
circulation pipes to the boiler. These circulating pipes are connected by a branch
pipe, having a stop cock and a syphon trap therein, to a pipe leading from a liquid
supply tank beside the cistern. The boiler and the pipes connecting same to coil,
are first filled, preferably by placing in the empty liquid tank sufficient liquid of a
non-furring character, and opening the stop cock in the branch pipe, the air displaced
froin the boiler and coil, by the entering liquid, passing off through an ordinary air
vent pipe turned over the liquid tank. The cold water cistern may now be filled
with water, which flows into and fills the hot water tank the latter being provided
with an expansion pipe leading to the sink, lavatory, bath and other supply in the

ordinary way. The apparatus is then ready for immediate use.
started the apparatus is continuous, the liquid in the coil circulating continuously
through the boiler and through the coil and its connecting pipes heating the water
contained in the hot water tank outside the coil as the liquid passes therethrough
back again to the boiler.

We, WILLIAM HENRY BUSHELL, Managing Director of the Tubular Bath Boiler
Company Limited, of 184, Gray's Inn Road, in the County of London, and THE
TUBULAR BATH BOILER COMPANY LIMITED, as aforesaid, 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 :-
In hot water circulating systems as heretofore constructed and arranged, the water
flows from the ordinary cistern into a hot water tank which is connected by circulating
flow and return pipes with the boiler. The water is heated in its passage through
the boiler and is drawn off from an expansion pipe connected to the upper part of the
hot water tank, or off the hot water flow pipe from boiler. Although this system is
otherwise well adapted for heating and circulating water, after a time the interior of
the boiler and the circulating pipes become choked with the sediment or furry deposit
resulting from the precipitation of the lime or other solid particles contained in the
water which is constantly circulating through them.
The object of this invention is to construct and arrange water heating and
circulating apparatus so as to prevent the furring of the boiler and circulation
pipes.
This object we accomplish by so arranging the apparatus that the water from the
cistern flows into the hot water tank where it is heated by a coil connected by
circulation pipes to the boiler.
Such an arrangement of apparatus is shown in the accompanying drawings wherein
A represents the cistern, B the hot water tank, C the coil therein, D and E the flow
and return circulation pipes, and F the boiler. These circulating pipes D and E are
connected by a branch pipe G, having a syphon trap therein, to a pipe J leading from
a non-corroding liquid supply tank K.
The boiler F and the pipes D and E connecting same to the coil, are first filled,
preferably by placing in the empty liquid supply tank K sufficient liquid of a non-
furring character. The air displaced from the boiler and coil by the entering liquid,
passes off through an ordinary syphon air vent L from flow pipe D to top of coil,
which vent L is then turned over the top of the liquid tank K. The cold water
cistern A may now be filled with water, which flows into and fills the hot water
tank B, the latter being provided with an expansion pipe M leading to the sink,
lavatory, bath and other supplies in the ordinary way. The apparatus is then ready
for immediate use. When once started, the apparatus is continuous, the liquid in
the coil C circulating continuously through the boiler F and through the coil and its
connecting pipes D and E, heating the water contained in the hot water tank B,
outside the coil, as the liquid passes therethrough back again to the boiler.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. Apparatus for heating and circulating water comprising a circulating system of
pipes and a hot water tank such as B in which is a coil such as C connected by
circulating pipes D and E to a boiler such as F said circulating pipes D and E being
connected to a non-corroding liquid supply tank such as K and furnished with a vent

described with reference to the accompanying drawing and for the purpose stated.
2. The method of and means for heating and circulating water substantially as
herein before described and illustrated in the accompanying drawing.
