PROVISIONAL SPECIFICATION.
An Improved Greenhouse Heater and Propagator adapted for use
with Oll or Gas Fuel.
I, HARRY PERCY PHILLIPS, of 308 Victoria Road, Aston, in the County
of Warwick, Designer, do hereby declare the nature of this invention to be as
follows:-
My invention consists of an improved greenhouse heater and propagator adapted
for use with oil or gas as fuel, and its object is to obtain greater economy in
the consumption of fuel with simplicity of construction and efficiency of
action.
In carrying my invention into effect I arrange a metal or other vessel, with
two water pipes, an upper and a lower one, connecting to a second vessel or
feeder.
Water fills both pipes and fills or partly fills both vessels, and, when heat is
applied continuous circulation proceeds, the heated water flowing along the upper
pipe and returning when cooled to some extent by the lower pipe.
The first mentioned vessel serves as boiler or heater and it has passing through
it one or two flues in which burn oil or gas lamps. The flues pass above the water
level but do not pass right through the boiler or heating vessel and the hot products
of combustion pass into the space above the water and impinge upon the bottom of
a propagating pan so as to heat the water in the pan and so warm the prepared
soil above and the plants placed in pots or other convenient receptacles. In one
arrangement the water is enclosed and the ends of the flues pass through a metal
plate or diaphragm into a chamber formed above this plate, the top being the
bottom of the propagating pan.
P.
The hot air discharges by an outlet pipe conveniently placed, and the waste heat
of the lamp or lamps is quite sufficient to heat a propagator of considerable
dimensions.
*
When oil lamps are used for supplying heat, I prefer to arrange them on
levers so that they may be readily raised into position and lowered. when
necessary for filling or trimming purposes. Slides however may be used instead
of.levers.
The vertical, flues serve as funnels to the oil lamps and are made of suitable
diameter to act instead of the usual glass funnels, used for petroleum or hydro-
carbon lamps. When gas is used as fuel ordinary jets of flame may be adopted,
but I prefer a Bunsen burner or burners.
...
The apparatus is provided with a suitable stand to raise it to a convenient
height and a cover is supplied to the second vessel to enable water to be supplied.to
make up for loss by evaporation.
The propagatory box is arranged to be lifted off the pan and the pan detaches
from the boiler or heater allowing free access to the flues; for.cleaning.

An Improved Greenhouse Heater and Propagator adapted for use
with Oil or Gas Fuel.
I, HARRY PERCY PHILLIPS, of 308, Victoria Road, Aston, in the County of
Warwick, Designer, 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 :-
My invention consists of an improved greenhouse heater and propagator adapted
for use with oil or gas as fuel, and its object is to obtain greater economy in
the consumption of fuel, with simplicity of construction and efficiency of
action.
Referring to the accompanying sheet of drawings
:-
Figure 1 is a sectional elevation of one arrangement.
Figure 2 is a horizontal section through the line c, y Figure 1.
Figure 3 is a section of another arrangement and
Figure 4 is a section as in Figure 3 but with a modified swivelling hot air
'chamber.
In carrying my invention into effect I arrange a metal or other vessel A, with
two water pipes B, C, an upper one B and a lower one C, connecting to a second
vessel or feeder D.
Water fills both pipes B, C, and fills or partly fills both vessels A, D, and when
heat is applied continuous circulation proceeds, the heated water flowing along
the upper pipe B, and returning when cooled to some extent, by the lower
pipe C.
The first mentioned vessel A serves as boiler or heater, and it has passing
through it one or two flues E, E in which burn oil lamps F, F or a gas lamp G or
lamps. The flues E, E pass above the water level but do not necessarily pass
right through the boiler or heating vessel, although so shown in Figure 1, and the
hot products of combustion pass into the hot air space H above the water and
impinge upon the bottom of a propagating pan I, so as to heat the water in the
pan, and so warm the prepared soil above and the plants placed in pots or other
convenient receptacles. In one arrangement as shown at Figure I the water is
enclosed, and the ends of the flues E, E pass through a metal plate or diaphragm
into a chamber H formed above this plate, the top being the bottom of the
propagating pan.
The hot air discharges by an outlet pipe K conveniently placed, and the waste
heat of the lamps or lamp is quite sufficient to heat a propagator of considerable
dimensions.
When oil lamps are used for supplying heat, I prefer to arrange them on levers
or rests so that they may be readily raised into position and lowered when necessary
for filling or trimming purposes. Slides however may be used instead of levers as
shewn at L.
The vertical flues E, E serve as funnels to the oil lamps F, F and are made of
suitable diameter, to act instead of the usual glass funnels, used for petroleum or
hydro-carbon lamps. When gas is used as fuel ordinary jets of flame may be
adopted, but I prefer a Bunsen burner or burners, as shown at G Figure 3.
Figure 2 is a section on .c, y (Figure 1) and the tubes E, E are shown as well
as the vessel A.
In the modification shown at Figure 3, a single flue or tube E is adopted through
which pass the products of combustion from the Bunsen burner E, but the other
parts are the same as in Figure 1 and are similarly lettered.
The apparatus is provided with a suitable stand to raise or lower it to n
convenient height, and a cover M is supplied to the second vessel D, to enable
water to be supplied to make up for loss by evaporation.

page_text: The propagatory box N is arranged to be lifted off the pan I, and the
pan I detaches from the boiler or heater A allowing free access to the flues for
cleaning.
In Figure 4 the single flue arrangement is shown as at E Figure 3, but the lot.
air chamber H is constructed to swivel round carrying with it the pan I and
box N if desired. The top of the vessel A is closed and the chamber H
placed loosely upon it so that the outlet K may be carried out at any convenient
point.
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 :-
1. A greenhouse heater and propagator arranged substantially as herein before.
described with reference to the accompanying drawings.
2. A greenhouse heater with attached propagator with propagator mounted above
the heater and heated by the waste heat, substantially as described reference being
had to the accompanying drawings.
3. A greenhouse heater with attached propagator, the hot air box supporting
the said propagator being arranged to rotate or revolve to set the discharge pipe
desired position as described.
