This invention relates to automobile coolers .
and has for its primary object, the provision of
The upper part of generator lbfhas a chamber
formed therein, within which is disposed a series ,
'a novel burner-'for cooling apparatus used for - of downwardly inclined baille plates to direct the
conditioning the normally closed-compartment of
5 anautomotlve vehicle, whether it be for _the pur
pose- of refrigerating said compartment or for
conditioning the air therein so that the same Willbe rendered comfortable for the passengers occu
pying the same.

Another important object of this invention is
the provision of _automobile cooling apparatus,
having as a part thereof, a generator which in
,cludes heating means that employs part of the
' fuel from the fuel supply system for the motor,
I 15 the supply of which is both manually and auto
matically controlled by means within the com
4
partment of the automobile.

A further object of this invention is to provide
cooling apparatus for automobiles which has as
.20 a part thereof, a unique generator comprising
parts which employ both electrical energy and a
condensate back to the lower part of generator'
40. wherein is disposed the novel heating means. 5
This heating means 46 is used to heat coils 48
which are in connection with theälower part'of
an evaporator through the medium of a conduit
EIL‘ The open end of coiled conduit 60 is di- ‘
rected against the underside and spaced from the 10
cap 62 which is normally submerged in the water
or other absorbing agent within generator 40.
Burner I6 comprises a coil 64 which terminates
in an upwardly _d_irected’nozzle 56, from which
the gasinea fuel is projected after passing' 16
through-sa‘id coils 54. A portion of coils 6I is
surrounded by heating coils 58 which are` re
moved from the end of pipe 50 forming'nozzle 56
a suilicient distance so that generating a gas will
be insuredV Prior to the liquid fuel reaching. 20
nozzle |56. This coil 54 receives its fuel from a4
part of the fuel -supply for the automobile motor, . source of fuel supply for nozzle 56 through a ,
-such employment being through the medium oi’
specially formed and novel valve and switch ele
25 ments, to the end that operation of the entire
cooling apparatus is rendered easy to start and
, stop and ismade automatic between these times
and during. the continued operation of the appa
ratus.

With the foregoing general objects in view and
with minor objects in mind that will be made
_clear during the course of the following speciñca
tion, one form of the invention will be described
L_ by reference to the accompanying. drawing,
'
wherein:

Fig. 1 is a partially diagrammatical, fragmen
tary view through the lower portion of the' gen
erator of an automobile cooling apparatus and
showing its’connection with a manual control lo
" 40 cated on the instrument board.
_ Fig. 2 is an enlarged, diagrammatical, sectional
view through the~ thermostatically controlled
valve which is actuated by compartment tem
perature to control the supply of fuel.v
Fig. 3 is a centralsection through the manu
conduit 62, within- which is interposed a thermo
statically controlled valve 64. This valve 64 is
always partially open and when a change of tem- 25 '
perature takes place within the compartment be
ing conditioned, valve 64 is further opened or
partially closed, as the case might be. The valve
stem of valve 64 is reciprocated 'as the tempera
ture within said compartment is changed. 'This 30
~`action takes place because ofthe increase or de
crease in volume of the gas within thermostat 66 '
which acts upon the diaphragm in connection
with the valve stem as shown in Fig. 2. Such
thermostats are of the commercial type and well 5
known in the art.
.
»
It is notable that this thermostat 66 should ‘bel
positioned within the compartment being condi
tioned by the cooling apparatus of -which the
burner, shown in Fig. 1, is a part. If the tem
perature in the compartment increases, thermo
0
stat 66 will act to open valve 64 to cause a greater _
amount of fuel to reach burner 66 thereby to
speed up the flow of refrigerant'through the cool
ing apparatus for the purpose of lowering the 45
temperature in the compartment to the desired
'
Fig. 4 is a cross section through the same,
degree. When the temperature is lowered ther-l
taken on line VI-VI of Fig. 5, and
mostat 66 will serve to close valve64. Thus valve

6l will be opened and closed to speed or retard
