Improved Apparatus for Heating Greenhouses and other Buildings
with Gas.
I GEORGE LEE of 102 Grosvenor Road Bristol, in the County of Gloucester Gas-
Engineer, do hereby declare the nature of this invention to be as follows:-
The Apparatus consists of three vertical Cylenders A B (Fig. 1 any convenient
distance apart, connected with horizontal pipes. At the bottoms of the Cylenders A
and B are Gas burners, the heat from which rises and passes along the pipe D into
the Cylender C, through which it descends and passes along the lower pipe E to the
point F thence to the outside of the building through the pipe G. The air for
supplying the Gas burners is brought in from the outside of the building through
the pipe H. The inlet and outlet pipes may be carried along or underneath the floor
as may be convenient. On the top of each Cylender is a cover with a rim which
fits into a trough I Fig. 2 filled with sand to form a seal against the escape. of
noxious fumes into the house. For Greenhouses the covers take the form of basins J
Figs. 1 and 2 to hold water for evapouration.
For lighting, the covers are removed and the light applied with a taper.
A small glass eye K for inspection is provided in each generating Cylender.
A smaller heater is constructed by dispensing with the Cylender B and connecting
the Cylenders A and C with the pipes as in Fig. 3.
Figures 2 and 4 are sections of Figs. 1 and 3. The arrows indicate the direction
of the air currents.

page_text: I GEORGE LEE of 102 Grosvenor Road Bristol, in the County of Gloucester,
Gasfitter and Plumber, 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 the following description of this invention I refer to. the drawings left with the
provisional specification.
The Apparatus consists of vertical cylinders A. B. C. Fig 1. connected with
horizontal pipes D. D. H. E. At the bottoms of the cylinders A and B are gas
burners. The heated air generated in the Cylinder A, rises and passes through the
pipes D D. Also the heated air from the burner in the Cylinder B rises and passes
together with that from the Cylinder A into the Cylinder C. through which it
descends and returns through the lower pipe E. to the point F (which may be in
any part of the pipe E) thence to the outside of the building through the pipe G.
The air for supplying the burners is brought in from the outside of the building
through the pipe H which communicates with the bottoms of the Cylinders A and B.
The inlet and outlet pipes may be carried to the outside of the building on a level
with the pipes E and H. or along the floor or underneath the floor as may be
convenient.
On the top of each cylinder is a cover having a rim which fits into a trough I.
Fig. 2 filled with sand or other material to form a seal against the escape of noxious
fumes into the house. If necessary these covers take the form of basins J. J.
Figs. 1 and 2, to hold water for evapouration.
For lighting the covers are removed and the light applied with a taper.
A small glass eye K. Figs. 1 and 3 for inspection is provided in each generating
cylinder.
A smaller apparatus is made by dispensing with the Cylinder B. and connecting
the Cylinders A and C. with the pipes as in Fig. 3.
Figs. 2 and 4, are sections of Figs. 1 and 3. The arrows indicate the direction of
the air currents.
I make this apparatus partly of sheet iron and partly of cast iron, or wholly of
sheet iron, or wholly of cast iron, or of any other metal or other material.
I do not confine myself to any number of vertical or generating Cylinders, or to
any length of horizontal pipe, neither to any particular form of burner.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1st. Any form of Gasheating Apparatus by which the products of combustion are
conveyed direct to the highest point, thence through any length of pipe at the end
of which it is made to descend and return along a lower pipe to be discharged at or
below the level of the burner.
2nd. Any form of Gas-heating Apparatus by which the light is applied to the
burners by removing a cover from the top.
3rd. Any form of Apparatus the distinctive features of which are comprised in the
foregoing statement.
