3 Claims.

This invention relates to new and useful improvements in a heater for motor vehicles and boats.

The invention contemplates arranging the 5 water and steam heater within the vehicle so:

as to supply heat during the Winter.

A further object of the invention is the provision of a mechanism for automatically controlling the supplying of water to the heater,

10 when the radiator of the motor vehicle is supplied with the water.

Another object in the construction of adevice as described which is simple and durable and which can be manufactured and sold at a rea- 5 sonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth;

In the accompanying drawing forming a material part of this disclosure:-

Fig. 7 is a fragmentary view similar to Fig. 2 but illustrating another embodiment of the 45 invention.

The heater for motor vehicles and boats, ac-

cording to this invention, is used in combination with a motor I having an exhaust III and a water radiator I O for the cooling thereof. In 50 Fig. 1 an automobile II is illustrated equipped with the motor to which the heater, according to this invention, is applied.

The heater comprises a hollow casing I2 with a plurality of air passages I3 from the front to 55 the back, these passages comprising merely tubes, and said casing being adapted to be located in the body of the vehicle as indicated in Fig. 1; preferably upon the dashboard to supply heat to the vehicle.

A fan I4 is adapted to blow atmospheric air through the passages I3. A means is provided for operating the fan. A water coil I5 is arranged in the exhaust I 0 for boiling water, and is connected by top and bottom pipes I6 and I1 respectively with top and bottom portions of the casing I2 for conveying steam and water, respectively.

The fan I4 is supported upon a shaft I8 of a steam turbine I9 mounted within the casing I2. The pipe I6 is connected with the steam inlet for the turbine. The outlet for the turbine is indicated by reference numeral HF and discharges within the casing I2. The details of the turbine will not be given in this specification as they form no part of the invention and steam turbines are generally known. The basic principle is that steam travelling at a velocity is directed by nozzles against buckets on a rotor. The rotor is connected with the shaft I8. This steam turbine comprises the means for operating the fan I4.

The water coil I5 is enclosed in a tube 20 which is attached by couplings 2| and 22 upon the ends thereof, with the exhaust Ill This is possible by first removing a portion of the exhaust pipe and substituting the tube 20 in its place. The tube 20 is of a larger diameter than the exhaust so as to compensate for the compass taken up by the coil I5 and not impair the travel of the exhaust gases. The pipe I6 connects with the top of the coil I5. The coil is either arranged vertically, as disclosed in the form of the invention illustrated in Fig. 7, or at an inclination as shown in Fig. 2. It must have one end at a higher elevation than the other end. .The pipe ll connects with the lower end of the coil. The pipes I6 and I! are connected with the coil I5 by couplings 23.

The exhaust I 0 is provided with a by-pass I I] which extends from a point above the coil I5 to a point below the coil I5. A deflecting valve 25 is arranged at the top junction of the by-pass and the normal exhaust line, and controls the flow of the exhaust gases through one passage to the other. More particularly, the valve 25 is a butterfly valve operated by a handle 26 located upon the outside of the exhaust pipe. In one position, the valve 25 engages upon a seat 21 which is obliquely across the exhaust passage leading to the coil I5. In another posi- 'the coil IE to boil so that the steam passes through the pipe l6 and discharges into the turbine I9, and from the turbine discharges into the top portion of the casing l2. This heats the air tubes and the atmospheric air will be heated from the tubes.

A means is provided for automatically supplying the heater with water whenever the radiator ||l of the vehicle is supplied. This is necessary, as some of the water 30 will be continuously lost due to leakage in the systems and evaporation. A pipe 3| connects the water supply line I! with the water compartment of the radiator l A valve 32 is interposed in the pipe line 3|. This valve is operated by a handle 33. The handle 33 connects with a rod 34 which is slidably mounted in a standard 35 attached on the radiator Ill. The upper end of the rod 34 extends through an opening 36 in the neck of the radiator I and terminates in a vertical portion 34' engaging against the radiator cap 31. A spring 38 acts between the standard 35 and a collar 39 on the rod 34 for normally urging the rod upwards. The rod is restrained by the cap 31. When the cap 31 is removed, as is necessary when water is added to the radiator ID, the rod 31 will be moved upwards by the spring 38. This motion opens the valve 32. The valve normally is closed.

In Fig. 7 another embodiment of the invention has been disclosed which distinguishes from the prior form in two respects. First, the coil I is arranged in the vertical as previously explained. Second, the by-pass Hi is connected by the pipe fittings with the exhaust pipe I 0. Furthermore, a valve 40 is interposed in the by-pass and a valve 4| in the exhaust I0- above the coil l5. Thus, one valve or the other may be opened to direct the exhaust gases either through the bypass or around the coil IS. The valves 40 and 4| are hand operated.

While we have illustrated and described the preferred embodiment of our invention, it is to be understood that we do not limit ourselves to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of our invention as defined in the appended claims.

Having thus described our invention, what we The operation of the device conclaim as new, and desire to secure by United States Letters Patent is:-

1. In combination with a motor having a hot exhaust, a heater casing with air passages from the front to the rear for location in the body of the vehicle, a fan adapted to blow air through said passages, means for operating said fan, a water coil in said exhaust for boiling water, top and bottom pipes connecting the ends of said coil with top and bottom portions of said casing for conveying steam and water respectively to and from the coil and the heater casing, said motor having a water radiator with a removable cap, and a water supply pipe connected with said radiator and controlled with a valve operated by an operator actuated when said cap is removed.
