Specification of Letters Patent.

Application filed January 16, 1912. Serial No. 671,460.

utilizing the heat from the exhaust thereof.

The invention relates also to a particular form of radiator to be used with such means.

Herein I show only two forms of the invention in which the exhaust pipe of the motor is surrounded bya suitable water jacket or heater connected to radiators in the cab of the automobile, but it is understood that other forms may be used without departing from the scope of the invention as claimed, and that the heating means may be used for inclosures other than the cabs of automobiles.

In the accompanying drawing Figure I is a side elevation partly in section showing the heating means applied to an automobile; Fig. 2 is a sectional view taken on the line 22 of Fig. 1, parts being broken away; Fig. 3 is a vertical longitudinal sectional view of one form of water jacket; Fig. 4 is a similar view of another form of water jacket, and Fig. 5 is a horizontal sectional view of a detail, taken on line 55 of Fig. 2.

Referring more particularly to the drawing, the heating arrangement is shown applied to an automobile having a body or cab and a motor provided with an exhaust pipe 12 and a mufiier 14 which may be supported in any usual or convenlent manner. At a convenient point between the ends of the exhaust pipe, a water jacket or heater 15 is inserted. This heater may, as shown in Figs. 1, 2 and 3, comprise a cast metal water jacket provided with a central opening 16 (Fig. 3) into which the exhaust pipe is screwed as shown, and a water space 17 completely surrounding the central opening. The hot exhaust gases pass through the central opening 16 and communicate heat to the water or other conducting fluid in the space 17 the water passing in at the openin 1 8 and out through the opening 19. instead. of the heater shown in Fig.

3 other forms may be used, for instance, the heater 15 shown in Fig. 4. This heater 15 consists of a main drum 16, tubesheets 17 and tubes 18 connected atopposite ends to the exhaust pipe 12 by suitable heads 19 forming end chambers 20. The hot gases pass through the exhaust pipe, the'cham- Patented Sept.1, 1914.

bers 20 and tubes 18' to the muliler, while the water circulates in the space bounded by the drum 16, the sheets 17 and the tubes 18, passing in at the opening 21 and out throughthe opening 22. Both forms of heaters are provided with suitable drain cocks, as shown. The openings 18 and 19 of Fig. 3 (or the openings-21fand 22' of'Fig. 4) are provided with connecting pipes 21 and 22 respectively, having branches 23 and 24, and 25 and 26, respectively leading to the foot-warmer 27 (Fig. 1) and the radiator 28 (Fig. 2), in the cab or body of the automobile. The return branch 25 is connected by means of the pipe 28 with the expansion tank 29.

In order that-the radiator tubes 30 of the radiator 28 may remain horizontal so as not to interfere .with the circulation of water therein when the automobile is tilted to one side as when the automobile is resting at the curb of a street, the radiator 28 is suspended by a ball-and-socket 31 or othersuitable connection so that there maybe transverse pivotal movement relative to the automobile. Springs 32 hold the radiator 'against jarring or too sudden movement from side to side, while suitably secured spaced members 33 (Figs. 2 and 5) prevent a swinging movement from front to rear. In order to permit said transverse pivotal movements,

suitable flexible connections 34 and 35 are.

inserted in the pipes 24 and 26 near where they connect with the radiator. Suitable valves 36 and 37 are provided for said radiator and the foot-warmer, respectively.

The operation of the arrangement is as follows: Water is poured into the expansion tank until the water-jacket, radiator,

foot warmer, and all connecting pipes are entirely filled. The heat of the exhaust passing through the water-jacket heats the water therein and causes the water to circoils. The excess of water due to the expansion caused by the heat is stored in the expansion tank. If the wheels on one side of the automobile stand in a gutter or other depression "of the street, the radiator will ,culate in the foot-warmer, and radiator swing on its ball and socket joint and maintain a proper level in the radiator tubes, thus insuring a good circulation in the coils.

I claim as my invention:

1. Ina vehicle, the combination with the body, of a water heater, a radiator in the body, and pipes connecting the heater with the radiator, said radiator being pivotally supported at the upper part thereof to permit lateral swinging of the same, said pipes being provided with flexible connections v near where they join the radiator. e

2. In a vehicle, the combination of a Water heater, a radiator in the front part of the cab; a foot warmer in the lower part of the .cab, and pipes connecting the heater with the foot warmer and the radiator, said radiator being pivotally suspended to' permit transverse pivotal movement, said pipes being provided with flexible connections near where they oin the radiator.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
