WILLIAM EDGAR LEA, of Runcorn, in the County of Chester. IMPROVEMENTS
IN OR APPERTAINING TO BOILERS OR WATER HEATERS FOR HOUSHOLD AND OTHER
PURPOSES."
This Invention has for its object a boiler not liable to explode, one that can be
taken in and out without injuring the brickwork, and one of a cheap serviceable
character. It consists:-1st. Of two pipes joined at a series of preferably equi-
distant points in their length, and at one of their terminations by transverse pipes
preferably at right angles. This apparatus I place at the back of the grate, and
prefer to allow the gasses to pass through between and round the cross tubes. At
the junctions I prefer to round the upper parts of the joints between the cross pipes
and the vertical ones, so that water can more easily pass into and out of the cross
pipes to or from the main or entrance and exit pipes. The lower part however of
said joints I make angular, so as to cause the water to be more naturally diverted
in part into the cross pipes. These pipes can be wrought and built up with elbows
and unions, or be solidly cast in one piece of cast iron, brass, or other material. To
the two main pipes I attach the entrance and exit pipes, or sometimes I attach one
or more of these boilers and make the water circulate through all; one being at
the back, the other two at the sides, or two at the back of one large furnace.
To assist in getting out the core from the transverse pipes, and also to more easily
clean out the apparatus, I place plug holes preferably alternately on each side on the
D

page_text: main pipes opposite the ends of the cross pipes. These plug holes are plug with
screws with squared heads so as to be easily removed when desirable.
Besides acting merely as a household boiler, this apparatus will be found appli-
cable for warming greenhouses, heating hot water pipes, and other kindred uses.
SPECIFICATION in pursuance of the Conditions of the Letters Patent filed by
the said William Edgar Lea in the Great Seal Patent Office on the 30th July
1878.

IN OR APPERTAINING TO BOILERS OR WATER HEATERS. FOR HOUSEHOLD AND OTHER
PURPOSES."
This Invention has for its object a boiler not liable to explode, one that can be
taken in and out without injuring the brickwork, and one of a cheap, serviceable
character. It consists-1st. Of two pipes joined at a series of preferably equi-
distant points in their lengths, and at one of their terminations by transverse pipes,
preferably at right angles. This apparatus I place at the back of the grate, and
prefer to allow the gases to pass through, between and round the cross tubes. At
the junctions I prefer to round the upper parts of the joints between the cross pipes
and the vertical ones, so that water can more easily pass into and out of the cross
pipes to or from the main or entrance and exit pipes. The lower part however of
said joints I make angular, so as to cause the water to be naturally diverted
in part into the cross pipes. These pipes can be wrought and built up with
elbows and unions, or be solidly cast in one piece of cast iron, brass, or other
material. To the two main pipes I attach the entrance and exit pipes, or some-
times I attach one or more of these boilers and make the water circulate through
all, one being at the back, the other two at the sides, or two at the back of one
large furnace.
To assist in getting out the core from the cast transverse pipes, and also to more
easily clean out the apparatus, I place plug holes, preferably alternately, on each
side on the main pipes opposite the ends of the cross pipes. These plug holes
are plugged with screws with squared heads, so as to be easily removed when
desirable.
Besides acting merely as a household boiler, this apparatus will be found appli-
cable for warming greenhouses, heating hot-water pipes, and other kindred uses.
DESCRIPTION OF DRAWINGS,
In which like letters refer to like parts in all Figures.
Fig. 1 shews an elevation of my improved boiler cast in one piece. A are the
upright pipes; B, the transverse ones; E, the plug holes above referred to for
cleaning and other purposes; D, D, return and flow sockets; the connections can be

page_text: made any way, so long as the water is free to circulate through the boiler. Fig. 2,
section of same.
Fig. 3, view of boiler with part removed, arranged diagonally so as to form the
bridge to the furnace. In this, A is the upright pipe; B, the transverse ones; D,
flow socket and pipe; D', cock on same; F, fire-grate.
Fig. 4, view of same kind, but the boiler placed upright.
Fig. 5, side view of several boilers connected together by the flow and return
sockets.
Fig. 6, transverse section of the same, shewing the arrangement of elbowed pipe G
which I prefer for coupling several boilers together.
The arrows shew the direction of the escape of the products of combustion through
the flue or uptake.
It will be seen that the tubes A might be inclined from the perpendicular, or be
formed spirally, and also that the tubes B might be similarly formed, but this is
only a modification of my Invention.
Having now described my Invention, and the best mode known to me of
carrying it into effect, I wish it to be understood that what I believe to be new
and desire to claim under the herein-before in part recited Letters Patent is,-
1. A boiler for heating water for domestic and other purposes, composed of two
or more simple upright or inclined pipes or tubes connected to each other by
horizontal, inclined, or other tubes at approximately right angles thereto, so
that the water or other fluid is free to circulate through the whole either way
for the purposes described.
2. The combination of the tubes or pipe A with the pipes B, plug holes and
plugs E, and outlets and inlets D, D, for the purposes described.
3. The general arrangement of apparatus for heating fluids for warming and other
purposes, substantially as described.
In witness whereof, I, the said William Edgar Lea, have hereunto set my
hand and seal, this 23rd day of July, in the year of our Lord 1878.
