A New or Improved Tubular Water Heating Apparatus for Heating
Greenhouses, or for kindred Purposes.
I, ALFRED HARRISON, Heath Road, Runcorn, Cheshire, Accountant, do hereby
declare the nature of this invention to be as follows:-
The apparatus comprises a number of metal tubes, preferably of wrought iron,
united by, and fixed into one common water-way at each end.
Each water-way, made preferably of cast iron, is formed of two parts. The
inner or end plate is provided with socket holes corresponding with, and into
which the tubes fit.
The second plate or cover fits against the end plate with a washer between.
The water space is provided by the inner plate, or the outer plate, or both
being made hollow.
The apparatus is held and pressed together by a bolt or bolts passing through
one, two, or more of the tubes, and through suitable holes provided in the outer
plates of the water-ways. Nuts are employed as usual, or any other suitable
tightening arrangement for the bolts.
The joints in the sockets into which the tubes fit, are made water-tight with
washers, preferably of indiarubber.
These joints may be protected from the action of the fire by so placing the
heating apparatus on the brickwork of the fireplace, that the water-ways will
project outside or beyond the brickwork.
The shape of the apparatus, and the number and size of the tubes may vary
according to the size and power of the apparatus required.
The flow and return pipes may both be fixed in one water-way, or the flow at
one end, and the return at the other of the apparatus.

ALFRED HARRISON, Heath Road, Runcorn, Cheshire, Accountant, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The apparatus comprises a number of metal tubes preferably wrought iron,
united by and fixed into one common water-way at each end.

page_text: Each water-way made preferably of cast iron is formed of two parts.
The inner or end plate is provided with socket holes corresponding with and
into which the tubes fit.
The second or outer plate is made hollow in order to provide water space.
The second plate of each water-way is placed against the end plate with a
washer made of indiarubber or suitable material between, and the whole appa-
ratus is held and pressed together by a bolt or bolts passing through one two or
more of the tubes and through suitable holes provided in the outer plates of the
water-ways. The nut or nuts are screwed up against the outer plate.
The two plates of each water-way are provided with lugs through which suit-
able bolts with screwed nuts are passed to ensure. rigidity.
The joints in the sockets into which the tubes fit are made water tight with
fire resisting cement or other suitable material.
The joints may be protected from the action of the fire by so placing the heating
on the brickwork of the fireplace that the water ways will project beyond or out-
side the brickwork on each side of the fire.
The number and size of the tubes may vary according to the size and power
of the apparatus required.
In the accompanying drawings
Fig. 1 is a front elevation.
Fig. 2 is an end elevation.
A is the water tube.
B is the bolt to compress the apparatus together.
C is the inner plate of the water-way.
D) is the outer plate of the water-way.
E is the lug.
F is the washer between the plates.
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:-
1st. In a tubular water heating apparatus the use of bolts with screwed nuts
passing through the water tubes to compress the whole apparatus together, thus
providing for expansion and contraction, the bolts being subject to the same
variation as the tubes in consequence of being enveloped by the water in the
apparatus.
2nd. In a tubular water heating apparatus as aforesaid, the employment of a
water-way on each side of the fire such water-ways being made with two plates
or castings jointed with indiarubber or other suitable material, and made rigid
by bolts with screwed nuts passing through lugs as herein described..
Dated this 2nd day of June 1900.
