GAS HEATER
Hart, Los Angeles, Calif.
Application June 1, 1936, Serial No. 82,681
7 Claims. (Cl. 126—8'5)
My invention relates more particularly to a
type of gas heater which can be used as a port
able heater and moved from place to place, or
which can be permanently connected with the
5 gas supply in a room, and which stands above
the floor in the manner of a stand lamp and so
constructed and arranged that it develops a cir
culating heat current and also a radiated heat
directed downwardly and outwardly toward the
10 ?oor area surrounding the heater.
Amongother objects of my invention are: to
provide in a gas heater of the character referred
to, an improved burner, preferably in sections and
related so as to function as a circular burner unit,
yet composed of a plurality of sections each of
which receives its supply of gas and air and mixes
it for combustion at the discharge outlet of the
burner; to provide in connection with a gas
H
burner an overhanging heat radiating element of
(20 refractory material of the radiant type and
adapted to be heated by the combustion of the
gas mixture thereunder whereby to cause a de?
nite radiation of heat downwardly and outwardly
from said element or elements; to provide in a
£25 gas heater of the type referred to a construction
and arrangement of hood or body which is kept
cool around its outer surface, thus reducing any
danger to a minimum and preventing possibility
of ?re from contact of ?ammable material there
L30 with; to provide in combination with a gas burner
or heater of the character referred to an im
proved thermostatic control for regulating the
gas supply to the burner according to a pre
determined temperature which it is desired to
35 maintain; to provide a gas heater of the char
acter referred to having a supporting base casting
of such weight relative to the top and body there
of that there is little or no chance of its being
overturned from accidental contact therewith; to
40 provide a construction and arrangement which
permits of its being disassembled into small com
pass for packing and shipping; and, in general,
to provide an improved gas heater of the char
acter referred to which is practical, ei?cient,
45 economical and ornamental.
In order to fully explain my invention, I have
illustrated one practical embodiment thereof on
Figure 4 is a plan view looking down on the
base or feet and the thermostat control, taken
on line 4—4 of Fig. 1.
Referring now in detail to the drawing, I have
shown a base casting 5, having the legs or feet, 5
6, S, the top socket ‘I, and the dial supporting
parts, 8, 8, with a dial 9 supported therein, with
a revoluble dial indicator Ill, on the upper end
of a rod I I, threaded at its lower end through a
bracket-like member I2, forming a part of a ‘
thermostat, designated as a whole T.
Said thermostat T includes a casting I3, se
cured up under the base casting 5, with small
screws, as at I4, and having therein two gas
passages I5 and I6, leading to and from a cham 15
ber I'I, formed by a diaphragm I8, provided in
its center with a diaphragm gasket I9 positioned
and adapted to close the passage I5 to said cham
ber H’, as shown. Supported immediately be
neath said diaphragm I8 and adapted to engage
and move it is a thermostat wafer 20, attached
at its under side to a lever 2 I, pivotally supported
at 22 in the casting or bracket I2, with the outer
end of said lever 2| positioned under the end of
said threaded rod II, as shown. A sheet metal
housing 23 encloses the parts of said thermo
stat, as indicated, said housing having the vent
openings 23' around its lower end for tempera.
ture influence of the thermostat wafer. A gas
supply pipe 24 connects with the gas passage I5,
and this pipe 24 can be either pipe or hose, as
desired.
Screwed into the thermostat casting I 3, is a
vertical pipe 25, jointed at 26, to permit its being
taken apart. This pipe communicates with the
gas passage I 6 in the casting I3, as indicated.
A tubular shield 21 is placed down over the pipe
25 and seated in the socket l in the base casting
5, as shown. The upper end of the tubular shield
2‘! has seated thereon a cap 28, with opening
therethrough for the gas pipe 25, and it also is
formed to receive the lower end of an upper tu
bular shield 29, as indicated. Into the upper end
of the tubular shield 29 is ?tted a tapering collar
38, screwed on the upper end of the pipe 25, and
operating to force the tubular shields 2'! and 29

the base casting I6, and giving rigidity to the
now describe:
supporting structure and the base.

turned bead-like edges of said re?ector and shade,
and held in place by a screw bolt 35 up through
the outer ends of the arms 32.
Screwed down upon the top of the casting 3!,
is a triangular casting 3?, having its center open
to receive the tapered screw end of the gas pipe
25, and having gas passageways extending 3i’
outwardly through its three arm portions, as
10 seen in Fig. 2, and also in Fig. 1. The outer ends
of said arm portions are shown upturned or pro
vided with jet nozzles, as at 38, and are formed to

slots 132, at which the combustion takes place
around the full circle of the three burner bodies,
as shown.

Supported by means of small, brackets, 43, to
25 the inner middle part of the re?ector 33, is a
hollow shell-like structure 44, providing air space ,
insulation above the burner.
Suspended under
this shell member M, by a bolt 45, is a supporting
member 4-6, having its outer edge formed to sup
port the lower ends of radiant elements 47, the
upper ends or edges of which are supported by
means of struck-out lips 48, around the outer
edge of the lower member of the shell 44. Said'
radiant elements are of segmental form and when
35 placed together form a conical surface with the
usual small projections 41’ on their overhanging
surfaces. Supported around the burner head
4|, upon the arms 32, is a wire screen 49, for

that the burner is of the Bunsen type, is fastened
securely and will remain burning evenly.

of the sectional burner and enough distance be

tioned where the cool air is always more noticeable
near the floor and where it will function more
effectively to regulate the temperature of the
room according to the desire of those using it
and it can be set to function automatically to
maintain a predetermined temperature.
-I am aware that changes in the general con
struction and - arrangement of my improved
heater can be made without departing from the
spirit thereof, and I do not, therefore limit my
invention to the embodiment thereof shown and
described, except as I may be limited by the
hereto appended claims.
I claim:
,
base, a gas supply pipe having its lower end an
chored in said base and standing upright like a
stand lamp, a gas burner mounted on the upper
end of said pipe, a heat radiating member of 30
inverted'conical form supported by said pipe
centrally above said burner and adjacent there
to, whereby to be directly heated thereby, and
a surrounding shade supported by said pipe at
its upper end around said burner for re?ecting 85
radiated heat from said radiating member.

'
I have worked out a construction and arrange
ment of the several parts of my heater so as to
get the proper amount of heat radiated down
45 wardly and outwardly and the proper amount
of heat going up through the heater andcreat
ing a circulating current of heat, and also the
re?ected heat from the reflector. Consequently
my heater can be placed near furniture, close
50 to a wall or even against lace curtains without
any danger therefrom. The screen 49, not only
serves as a protection from the possibility of any
of the radiant elements falling out of place, and
as a protection to prevent children getting to
55 the ?ame, but the screen is an important factor
in preventing too much heat being radiated
downwardly.
The reflector 33, which is preferably made of
aluminum, is placed at just the proper angle to
60 reflect the heat outwardly in. all directions and
to the body of a person sitting close to the heater,
thus making for comfort. The outer shade or
body 34 is so placed with an inch or more space
for air between it and the re?ector 33, that said
65 outer shade 34 is always cool. The insulating
shell 44 above the burner and the radiant seg
ments prevents too much heat from passing up
ward through the center of the heater, and al
though a curtain or other article might be
70 blown over the top of the heater, it will not be
burned or damaged.
The base casting structure is suf?ciently heavy
relative togthe top part of the heater that it will
right itself even though it be tilted to an angle
75 of 25 degreesyand even though knocked over
