Description
E. E. VMULLER VEHICLE HEATER June 24, 1930.
Filed Jan. 24, 1928 l ln/vento@ il Zef/f APatented June 24, 1930 UNITED STATES ERNEST E. MILLER, 0E :DAVID CITY, NEBRASKA vEHIcLE HEATER A `Application filed Ia'nuaryi 24, 1928. Seriall No. 249,154.
This invention relates to heaters for vehicles propelled by internal combustion engines, and more particularly to 'a device of Vthis character, which employs hot water as a heating mediumr An important object of the invention is to provide a heating system of this type in which the engine cooling system. forms a source of supply for the water used in the heater in which the construction and ari accordingly the system has but a small effect upon the vordinary operation of the cooling system.
These and other objects I attain by the construction shown in the accompanying drawing, wherein for the purpose of illustration is 'shown a preferred embodiment of my invention a d wherein Figure 1 is a/longitudinal sectional view through a vehicle showing a heating system constructed in accordance with my invention applied thereto;
Figure 2 is ,a` horizontal sectional viewA through the radiator of the system;
Figure 3 is a section through the check valve.
Referring now\ more particularly to the drawing, theI numeral' 10 generally designates a water jacketed internal combustion engine, ll'the radiator thereof and 12 and 13 the usual lower and' upper tubes connect- `ing the radiator ,and the water jacket of the engine. The tube 12 may or may not include the usual circulation pump 14. The numeral 15 designates the exhaust manifold of the` engine and 16 that portion thereof which inclines downwardly and rearwardly to pass beneath the floorboards 17 of the vehicle to the usual muiiier (not shown). In accordance with my invention, I provide a tube 18 which is coiled about this' downwardly inclined portionv of the exhaust pipe. The lower end of the coil 18 is connected with the tube 12 through a check valve 19, while the upper end thereof is connected by a pipe 18a with a radiator 20. This radiator may be of any suitable type and is at present shown as a container having abaille y21 extending from oneend thereof at its center` to a point adjacent the opposite end, thus dividing ,the casing so as to provide a compartment of U-form in plan. The pipe 18a extends to one end of the compartment of the radiator 20, and a pipe 22 extends from the other end of the compartment to the tube 13. It will be obvious that the connec tion between the lower end of the coil 18 and the tube 12 of the cooling system should, where the pump 14 is employed, be connected between this pump and the radiator 11. The coil is preferably surrounded by a shield 23,
lWhile the connection lbetween the upper end of the coil and. the heater should vbe insufrom the tube 12. Thus, the coil 18 will be v continually filled with water which, when heated, will expand to the radiator 20, and this without a continuous circulation .of the water from the cooling vsystem of the automobile engine. An operation of this type is particularly desirable where the heating system is applied to autmobiles whose engines employ the thermo-syphonic system of. cir' culation. Attention -is directed to the fact that by the construction hereinbefore illustrated, the radiator 20 is arranged at a level below the upper end of the coil, so Ithat there will be no direct thermo-syphonic circulation inl the heating system.` A cut-olf is provided between the eoil and radiator, as indicated at25, and between the coil and check Valve 19 a drain valve 26 is preferably installed Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention. I do not limit myself to such specific structure except as hereinafter claimed.
I claim:-
In combination with the inclined exhaust manifold portion and the water cooling radiator of an internal combustion engine,
va Coil surrounding said manifold portion,
a pipe extending from the lower end of the radiatore to the lower end of the coil, a check valve in said pipe and seating in the direction of the radiator, a heater casing arranged in a horizontal planefintersectinlgr the coil and provided with a passage of U-form in plan, a pipe extending downwardly from the upper end of the coil to one end of the casingfpassage, and a pipe extending downwardly from the other end of the easing passage and then upwardly to the upper end of the radiator.
ln testimony whereof I hereunto aflix my signature,
' ERNEST E. MILLER.
