HEATER FOR MOTOR VEHICLES Filed Feb. 10, 1931 patented Oct. 9 1934 [TED STATES PATEN 1 Claim.
My invention relates to a heater for motor driven vehicles.
The primary object of the present invention is to provide a heater which may be readily installed between the engine block and its inlet and exhaust manifolds without alteration of the connecting parts comprising the power unit, and with a. minimum expenditure of time and labor.
With the foregoing and other objects in view which will appear as the description proceeds, the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein shown without departing from the spirit of the same.
In the drawing accompanying this specification:
Figure 1 is a side elevation of the heater, with parts broken away and in section, showing the heater installed between the engine block-indicated in broken lines-and the intake and exhaust manifolds of the power unit, indicated in full lines;with parts broken away and a section.
Figure 2 is a cross-sectional view of the heater installed between the engine block and the inlet and exhaust manifolds, taken on or about line 2-2 of Figure 1.
Figure 3 is a cross-sectional View of the same taken on or about line 3-3 of Figure 1.
Figure 4 is a vertical longitudinal sectional view,-including a side elevation of a portion of the heater.
Referring now to the letters of reference placed upon the drawing:
A denotes an engine block, B a carburetor, C
a gas inlet manifold, D an exhaust manifold and E the usual fan of a motor vehicle power unit.
The heater F embodies a chambered casting,
divided by a substantially horizontal wall G extending the length of the casting, forming an air heating chamber H above the horizontal wall,-
the air chamber being divided by a plurality of vertical partition walls H spaced apart to provide narrow channels extending rearwardly from the flaring mouth H into which pure fresh air is forced by the fan E of the power unit.
594 Depending from the horizontal wall G of the casting into a compartment I beneath the air heating chamber are a plurality of ribs J, which serve to enlarge the heating surface over which a portion of the exhaust gas .is diverted by the lips L which extend into the path of the exhaust gas as it passes through transverse openings M in a relatively narrow wall N supporting the heater between the exhaust and inlet manifolds, and the engine block. The gases thus intercepted are directed upwardly through the ports 0 into the compartment I above.
In addition to the exhaust passages M, extending transversely through the wall N, are a plurality of inlet ports P, alternately disposed in relation to each other,which respectively couple the inlet manifold C, and the exhaust manifold D, with the cylinders of the engine. The forward end of the heating compartment beneath the air chamber is tapped to receive a downwardly directed exhaust pipe R, open at its discharge end, through which the diverted exhaust gas is released after passing over the ribs J depending from the lower wall of the heating chamber.
T, T are gaskets inserted between the engine 7 block and the supporting wall N and between the latter and the manifolds.
To install the heater, the inlet and exhaust manifolds are disconnected from the engine block and separated sufiiciently from the latter to admit the narrow supporting wall of the heater between the engine and the respective manifolds. Suitable gaskets T, T are then inserted between the engine and the supporting wall of the heater and between the latter and the intake and exhaust manifolds to insure a tight joint. The intake and exhaust manifolds are then engaged to the engine block as before, thereby securing the heater in position.
The rear end of the air heating chamber is then connected by a flexible pipe, not shown, with the body of the vehicle.
Having thus described my invention, what I claim is:
In a device of the character described, a cast 95. ing enribodyin a longitudinally disposed chamber divided by a plurality of partitions into narrow channels in which air may be heated as it passes between said partitions to the body of a vehicle; a compartment below said chamber to receive a portion of the exhaust gases discharged by an internal combustion engine in their passage to an exhaust manifold; a plurality of longitudinally extending ribs depending from the wall dividing the compartment fromI05 no air chamber; a relatively narrow wall integral with the chambered casting, adapted to be bolted between an internal combustion engine block and its inlet and exhaust manifolds, said narrow wall having transverse ports to connect into the compartment below the air heating chamber; said compartment below the air heating chamber at its forward end having a downwardly extending neck open for the discharge of the exhaust gases delivered to the compartment.
