This invention relates to motor vehicle heaters, and more particularly to that type of motor vehicle heater wherein the hot water of the cooling system of the motor is circulated through a radiator mounted within the vehicle body.
The important object of the invention is the provision of means for utilizing the wasted heat of the exhaust gases, to increase the heat of the water circulating through the radiator, thereby increasing the heating capacity of the radiator to the end that an exceptionally large radiator may be used to facilitate the heating of buses or the like.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawings:
Figure l is an elevational view illustrating a motor vehicle equipped with a radiator, and illustrating the system, forming the essence of the invention,
Figure 2 is a sectional view through the exhaust manifold of the motor, illustrating a pipe, through which hot water circulates, as formed integral therewith.
Figure 3 is a sectional view taken on line 33 of Figure 2.
Figure 4 is a sectional view through an exhaust manifold, illustrating a pipe as positioned there- Referring to the drawings in detail, the reference character 5 designates an internal combustion engine which is provided with the usual exhaust manifold 6 and radiator 1 through which the cooling liquid of the internal combustion engine circulates, to maintain the engine cool.
The reference character 8 designates a heater, which is in the form of a radiator, mounted within the vehicle body, the radiator being supplied with hot water from the cooling system of the internal combustion engine, through the pipe 9 which is tapped into the water jacket of the internal combustion engine. A pipe H) connects with the pipe 9, through the valve housing I I. Connected with the valve housing Ii, is a flow pipe [2 that extends downwardly and connects with one end of the water-heating pipe l3 which is formed integral with the exhaust manifold 6.
One end of the pipe I3 is connected with the valve housing is, through the pipe I5. This valve housing M is in communication with the exhaust end of the radiator 8, through the return pipe It.
The reference character I! designates the return pipe of the system, and as shown, connects with the valve housing M at I 8, the opposite end of the pipe i! being connected with the return pipe l9 of the engine cooling system.
The reference character 20 designates a drain pipe which is also connected with the valve housing l4, whereby the cooling liquid may be drained from the system. The valve operating in the valve housing H, is indicated by the reference character 2!, and is provided with a groove or passageway 22 so that the valve may be moved to establish communication between the radiator 8, pipe l2 and pipe 9, so that the cooling liquid may pass through the pipe l3 to be heated by the exhaust gases passing through the exhaust manifold. The plug 23 of the valve operating in the valve housing M, is provided with a passageway 24 and a passageway 25. The construction of this plug 23 is such that it may be moved to establish communication between the pipe l3 and radiator, through the pipe H5, or it may be rotated to a position to cut off the flow of cooling liquid through the pipe l3, should it be desirable to decrease the heat. In this way it will be seen that the circulation will be through the cooling system of the motor, through pipes 9, l6, l1 and the radiator 8.
The valves are controlled by means of the control rod 26 that extends to a point in proximity to the operators seat, whereby the operator may have easy access thereto. The rod25 connects with the bell crank lever 21 that connects with the valve operating in the valve housing II, the bell crank lever 27 being connected with the rod 28, that in turn connects with the arm 29 of the valve plug 23. Thus it will be seen that by operating the rod 28, the valves may be moved to establish circulation between the radiator 8, water jacket of the motor vehicle, and return pipe i1, independently of the pipe [3. If it is desired, the rod 26 may be operated to establish communication between the pipes 9 and I3 to the end that in addition to the cooling liquid being heated by the heat of the cylinders, the Water will be heated by the exhaust gases passing through the manifold 6, to a higher degree of temperature prior to the passage of the water through the radiator 8, thereby greatly increasing the heating capacity of the radiator 8.
As shown by Figure 4 of the drawings, the pipe which is indicated by the reference character 30, is one which has been positioned in the usual exhaust manifold, which is indicated at 3!. It will of course be understood that in using a pipe of this character, the pipe is used to convert the usual exhaust manifold for use with applicants system. The pipes 12 and I5 will be connected with the ends of the pipe 39, in the same manner as shown by Figure 2 of the drawings.
What is claimed is:
The combination with the water cooling system and exhaust pipe of a motor vehicle internal combustion engine; of a heating system comprising a radiator mounted in the Vehicle; a water heating pipe within the exhaust pipe, the ends thereof extending through the Wall of the exhaust pipe; a first supply pipe and a first return pipe connecting the ends of the water heating pipe with the cooling system; a second supply pipe connecting the radiator with the first supply pipe at the junction of the first supply pipe and the water heating pipe; a second return pipe connecting the radiator with the first return pipe at the junction of the first return pipe and water heating pipe; a valve at the first mentioned junction arranged to provide communication between the first supply pipe, the water heating pipe and the second supply pipe in one position, and between the first supply pipe and second supply pipe only in another position of the valve; and a valve and drain pipe at the second mentioned junction, arranged to provide communication between the second return pipe and the water heating pipe only in one position, and independent communication between the first and second supply pipes, and the water heating and drain pipes respectively in the other position of the valve.
