2 Claims. (Cl. 257-241) This invention relates to automobile heaters and more particularly to such heaters as are generally attached to the exhaust manifold of an internal combustion for utilizing the heat of the exhaust gases for supplementing the normal heat of the water in the cooling system as it circulates between the cooling system and the radiator heater of the automobile.

An object of the present invention is to improve generally upon such types of heaters; the object, intent and purpose of the invention being to provide a device of this character which may be readily interposed between the exhaust manifold and the exhaust conduit of the internal combustion engine, and also readily connected with the water system for supplying water to the radiator of the automobile heater at a temperature which will be effective for raising the temperature in the interior of the automobile body.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a view showing generally the application of the invention.

Figure 2 is a horizontal sectional view taken substantially on the line 2-2 of Figure 1.

Figure 3 is a vertical sectional view taken substantially on the line 33 of Figure 2.

Figure 4 is an end elevational view of the water heater, and

Figure 5 is a vertical sectional view taken sub stantially on the line 5-5 of Figure 3.

Referring more in detail to the drawings, it will be seen that in accordance with the present invention, the preferred embodiment thereof consists of a water heater indicated generally by the reference numeral 5 and adapted to be connected, as shown, and hereinafter more fully described, with the internal combustion engine, the water cooling system of the engine, and the radiator of a conventional automobile heater for supplementing the normal heat of the water in the cooling system by causing the water in the cooling system to absorb heat from the exhaust gases as the water passes to the radiator of the automobile heater.

In the embodiment illustrated, the heater 5 embodies a casing 5 of suitable dimensions and design and formed with an internal integral formation 6 that forms a heating chamber opening through one side of the casing 5- as at I, and as clearly shown in Figure 5.

For mounting the casing 5 of the water heater, there is provided a bracket 8 in the form of a single casting that embodies a tubular section 8 adapted to be interposed in the connection between the exhaust manifold III of the internal combustion engine II and the exhaust pipe l2 as shown in Figure 1. To this end the tubular part 9 of the bracket 8 is provided at its respective opposite ends with apertured flanges I3 through the medium of which and bolts or other suitable fastening elements the tubular part 9 of the bracket is secured in the connection between the exhaust manifold I0 and the exhaust pipe i 2.

The bracket 8 also embodies a substantially hollow formation l4 that forms a by-pass opening at its respective opposite ends into the bore of the tube 9 adjacent the upper and lower ends of the tube, and intermediate said ends having an opening 15 that registers with the opening 1 provided in the side of the casing .5 for the heating chamber 8.

At the opening 15 the bracket 8 is provided with an apertured flange I8 through the medium of which and bolts or other fastening elements H the :racket 8 is secured to the water heater casing The casing 5 of the water heater 5 receives water from the circulating system of the internal combustion engine through the medium of a hose connection l8 between the water pump l9 of the internal combustion engine and an intake nipple 20 that extends down into the casing 5 from the top thereof as shown in Figures 1 and 3.

The heated water from the casing 5 of the water heater is delivered to the radiator of a conventional automobile heater 2| through the medium of a flexible hose 22 that at one end thereof is connected with an outlet nipple 23 that projects upwardly through the top of the heater casing 5, and at its opposite end is connected to the inlet nipple 24 of the radiator of the heater 2!.

The outlet nipple of the radiator of the heater 2| is connected with the water circulating system of the internal combustion engine through the medium of a return conduit 25 as shown in Figure 1.

From the description of the invention thus far it will be seen that the heat of the exhaust gases diverted into the heating chamber 6 will serve to materially raise the temperature of the water in the casing 5 and when the water in the casing 5 is heated sufficiently, circulation of that water is induced; the water flowing through the hose connection or conduit 22 into and through the radiator of the automobile heater 2| and from which the heat is distributed into the vehicle to be heated by the usual fan (not shown) and which forms a part of such heater 25.

For controlling the supply of the exhaust gases to the heating chamber 5, or for sending the exhaust gases around the heater as desired, there is provided in the by-pass it a butterfly valve pivoted as at 26', and operable from the instrument board of the vehicle by means of a link 2? connecting the crank arm of the valve pivot 26' with the crank arm of an operating shaft and a control rod 29 that is connected at one end thereof to a second crank arm on the aioremen tioned shaft it). The shaft 28 is iournaled in suitable bearings at provided therefor on the top of the water heater casing Thus it will be seen that when the valve is in the position suggested by full lines in Figure 5,

exhaust gases will pass into the heating chain her at for heating the water in the casing 50; of the heater 5, and when the valve 2G is in the position indicated by broken lines in Figure 5, the exhaust gases are shunted around the heater so as to pass directly through the tubular mem her 9 of the bracket 28 from the exhaust manifold it to the exhaust pipe i 2. v

It is thought that the manner of installation, the operation, and utility and advantages of an automobile heater embodying the features of the present invention will be had by those skilled in the art without further detailed description thereof.

It is also to be understood that while I have herein illustrated and described the preferred embodiment of the invention, I claim all such forms of the invention to which I am entitled in view of the prior art and scope of the appended claims.

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