IMPROVEMENTS IN APPARATUS FOR HEATING AND CIRCULATING WATER
Year: 1884

page_text: I FRANKLIN HOCKING of 16 Spellow Lane, Liverpool, in the County of
Lancaster, Engineer, do bereby declare the nature of the said Invention for
IMPROVEMENTS IN APPARATUS FOR HEATING AND CIRCULATING WATER to be as
follows:-
My Invention retates to that class of apparatus for heating and circulating water,
in which the heated water flows from the upper part of the apparatus and the
cooler water is returned to the lower part of the apparatus; then re-heated and
recirculated, whether the apparatus is applied to the heating of water in a cistern,
or receiver, or in a length of piping.
The apparatus consists of a series of tubes, arranged round a central tube of
larger size; the outlets of the tubes are choked, so as to proportion the outlet to the
amount of the products of combustion. These tubes are contained within a casing
and between a top and bottom tube plate. The tubes may be choked by being
made tapered, or by having their outlets contracted, or partially stopped. The
upper part of the casing is provided with a branch for the outlet of heated water
and a branch at the lower part is provided for the return of the cooler water. The
apparatus is surmounted by a water cistern, which forms a cover to the top tube
plate. The underside, or bottom of the cistern is domed upwards, and the inner
edge is provided with a gutter to receive the condensed vapour, which is
occasioned by the vapour of the products of combustion coming in contact with
the cooler surface of the dome. A pipe is provided to lead the condensed vapour
into the return pipe of the apparatus. The cistern is provided with a lid, or cover
in which there are holes for the final escape of the products of combustion into the
atmosphere, or into a pipe leading to a chimney, or other outlet.
Instead of the dome cover above described a plain hood, with a gutter, may be
used through which the waste products of combustion are led away. The cistern is
filled with water and is connected to the return pipe of the apparatus and acts as a
supply and to keep the apparatus full.
When gas, or oil is used as the combustible, the apparatus is placed over a
chamber, which contains a "Bunsen," or other gas burner, or an oil burner, the

page_text: heat from which passes up through the tubes of the apparatus. When solid fuel
such as coke is used, the apparatus is placed over a chamber in which is a fire grate
and the central tube is used as a feeding tube to the fire grate and it is surmounted
by a supply box from which the fuel is fed through the central tube onto the grate
bars, the products of combustion passing up through the side tubes with the
contracted outlets. The apparatus is provided with a dome and cistern cover, or a
hood as before described through which the waste products of combustion are
conveyed to a chimney or other outlet.

I FRANKLIN HOCKING of 16 Spellow Lane, Liverpool, in the County of
Lancaster, Engineer do hereby declare the nature of the said Invention for
IMPROVEMENTS IN APPARATUS FOR HEATING AND CIRCULATING WATER and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My Invention relates to that class of apparatus for heating and circulating water,
in which the heated water flows from the upper part of the apparatus and the
cooler water is returned to the lower part of the apparatus; then re-heated and
re-circulated, whether the apparatus is applied to the heating of water in a cistern;
or receiver, or in a length of piping.
The apparatus consists of a series of tubes arranged round a central tube of
larger size; the outlets of the tubes are choked so as to proportion the outlet to the
amount of the products of combustion. These tubes are contained within a casing
and between a top and bottom tube plate. The tubes may be choked by being
made tapered, or by having their outlets contracted, or partially stopped. The
upper part of the casing is provided with a branch for the outlet of heated water
and a branch at the lower part is provided for the return of the cooler water. The
apparatus is surmounted by a water cistern which forms a cover to the top tube
plate. The underside, or bottom of the cistern is domed upwards, and the inner
edge is provided with a gutter to receive the condensed vapour, which is occasioned
by the vapour of the products of combustion coming in contact with the cooler
surface of the dome. A pipe is provided to lead the condensed vapour away. The
cistern is provided with a lid, or cover in which there are holes for the final escape
of the products of combustion into the atmosphere, or into a pipe leading to a
chimney, or other outlet.
Instead of the dome cover above described a plain hood may be used through
which the waste products of combustion are led away. The cistern is filled with
water and is connected to the return pipe of the apparatus and acts as a supply and
to keep the apparatus full of water.
When gas, or oil is used as the combustible, the apparatus is placed over a
chamber, which contains a "Bunsen," or other gas burner, or an oil burner, the heat
from which passes up through the tubes of the apparatus. When solid fuel such as
coke is used, the apparatus is placed over a chamber in which is a fire grate, and
the central tube is used as a feeding tube to the fire grate and it is surmounted by
a supply box from which the fuel is fed through the central tube onto the grate
bars, the products of combustion passing up through the side tubes with the
contracted outlets. The apparatus is provided with a dome and cistern cover, or a.
hood as before described through which the waste products of combustion are
conveyed to a chimney or other outlet.
The beforegoing being the nature and purposes of my Invention, I will now
proceed to describe more in detail how the same may be carried out into practical

heating and circulating water, where gas is used as the combustible.
Figure 2 is a plan shown in section through X X Figure 1.
Figure 3 is a sectional elevation of an apparatus according to my Invention for
heating and circulating water where solid fuel, such as coke is used as the
combustible.

J.
An apparatus constructed according to my Invention consists of a series of
tubes a arranged round a central tube b of larger size; the upper ends, or, outlets
of the tubes a are choked, by providing the tubes a with covers, or caps a¹ with a
central hole c of smaller diameter than the tube a. The tube 6 as. shown in the
example Figures 1 and 2 is also provided with a contracted outlet d. The tubes a
and bare contained within a casing A and between top and bottom tube, plates &
and h. Instead of choking the tubes a in the manner shown in the Drawing, they
may be choked by being made of taper form as shown at Figure 14. The upper
part of the casing A is provided with a branch B for the outlet of heated water and
the lower part of the casing A is provided with a branch D for the return of the
cooler water.,.
'
The apparatus illustrated at Figures 1 and 2 is surmounted by a water cistern E
connected to the casing A. by a pipe g. The,underside, or bottom of the cistern E
is domed upwards and is provided with a pipe k for the escape of the. products of
combustion and the inner edge is provided with a gutter i to receive the condensed
vapour which is occasioned by the vapour of the products of combustion coming in
contact with the cooler surface of the underside of the cistern E. The pipe ¹ is
provided to lead, away the condensed vapour from the gutter i. The cistern E is
provided with a lid, or cover E¹ in which there are holes for the final escape of the
remaining products of combustion into the atmosphere. The products may be led
to a chimney, or other outlet.
Instead of the dome cover and cistern as above described, a plain hood Ei
provided with an outlet pipe k as shown at Figures 2 and 4 may be used and the
cistern E may be arranged in any convenient position, or adjacent to; and connected
by a pipe to the casing A.
.
The apparatus illustrated at Figures 1 and 2 is shown arranged over a combustion
chamber F and heated by a Bunsen gas burner H and is shown provided with the
outlet and inlet pipes B and D which may be connected to a system of piping, or
other hot water apparatus through, which heated water is required to be circulated.
It will be evident that the pipes B and D can be dispensed with and the casing. A
provided with a draw off tap and the apparatus used as an ordinary hot water
apparatus.
The apparatus illustrated at Figures 3 and 4 is shown arranged over a fire grate F
provided with fire bars H and a door H¹: This apparatus is designed for burning
coke, or solid, fuel, which is supplied through the central tube b; which in this case
is left open at the top and provided with a hopper b¹ through which the fuel can be
supplied through the tube b onto the grate bars H.
