advantages of the invention will become apparent to the reader of the following specification.

In the drawings: Figure 1 represents a fragmentary side elevational view of the engine portion of an automo bile with its parts broken away -to show the heater installed.

Figure 2 is a top plan view of the radiator.

Figure 3 is a vertical sectional view through the boiler.

Figure 4 is a horizontal sectional View on line ftof Figure 3.

Referring to the drawings, wherein like numerals designate like parts, it can be seen in Figure 1 that the numeral 5 generally refers to the automobile construction which includes the usual cowl wall B to the rearward side of which is secured the radiator structure generally referred to by the numeral l'.

The numeral 8 generally refers to the boiler, while the numeral 9 denotes the reservoir.

The exhaust manifold is denoted by the reference 9 and has the exhaust pipe lil extending therefrom. The boiler 8 is interposed between portions of the exhaust pipe IIJ and consists of the outer shell I I and the internal shell I2 spaced from the shell II. This spacing of the shells is maintained through the use of upper and lower necks I3-I4 extending from the internal shell I2, the outer ends of these necks Iii-I4 being hanged as at I5 and these flanges overlaip the central portions of the ends of the outer shell, the parts being suitably secured together such as by welding. Threaded apertures are formed in the anges of adjacent portions of the outer shell II for receiving screws I5 which connect the flanges IB of the upper and lower portions of the pipe I0 to the upper and lower ends of the boiler. Of course, the two spaced shells II and I2 form a dead-air space for insulating the chamber formed by the inner shell through which the exhaust gases pass as they leave the upper portion of the pipe It to reach the lower portion of said pipe.

Into the upper portion of the shell I2 extends the pipe line I6 connecting to the vertical water coil Il in the shell I2. The lower end of this coil Il extends outwardly of the shell I2 and shell II to form the line I'i to the reservoir 9. The lower portion of the reservoir 9 is of the hopper type, while the top is open .and a drain 10 cock I8 is provided in the lower portion of the line II.

The radiator 'l is shown in` Figure 2 and consists of an elongated shell I9 supported by brackets 20 on the back board 2l located on the cowl wall 6. The pipe line Iii extends into the shell I5) and through the longitudinal partition 24 therein which terminates in the shell I9 in spaced relation to one end thereof to allow .a by-pass 22.

The shell IQ is thus divided into the side with which the pipe line I5 communicates and the side with which the return line 22 communicates, the line 22 extending to the top of the reservoir 9. A duct line 23 extends from the radiator tothe reservoir 9 so that excessive steam from the radiator to the reservoir. This line 23 connects with the radiator at a point adjacent the point where the inlet pipe IG discharges into the radiator as will be seen in Figure 2. This pipe 23 extends upwardly and then downwardly to form ya loop with its discharge end extending into the water in the reservoir. Thus, if an excessive amount of steam is formed at the inlet end of the radiator this steam will pass into the pipe 23 where practically all of the steam will be condensed as it enters the looped portion and this water of condensation will be returned to the system, the hot water flowing through the radiator, of course, returning to the reservoir through the pipe 22. This pipe 23, therefore, acts to remove steam or an excessive quantity of steam from the radiator and condenses the steam -so that the water in the system will not boil away as fast as it would if this pipe 23 is not used.

The shells I I and I2 can be formed in any suitable manner to permit the insertion of the coil Il though I prefer to form the shells in sections which will permit the coil to be put in place after which the sections of the shells are welded together.

While the foregoing specification sets forth the invention in specic terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departcan escape 2 ing from 4,the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A heating system for a motor vehicle comprising a boiler including a Water receiving coil, means for heating the coil by the products of combustion from the motor, an elevated Water containing reservoir, a pipe connecting the lower end of the reservoir With an end of the coil, a radiator, an inlet pipe connecting the other end of the coil with the radiator, a third pipe connected with the radiator adjacent the point Where the inlet pipe delivers the fluid into the radiator and said third pipe extending upwardly to a point above the reservoir Where the pipe is formed with a loop, 5

with the pipe extending from the loop partinto the reservoir and below the Water level thereof and a return pipe connecting the radiator with the .top of the reservoir.
