HEATER.

Application filed October 11, 1926. Serial No. 140,910.

This invention relates to heating devices for motor vehicles and the primary object is to provide a simple, practical and efficient attachment whereby the heat emanating from thecustomary muffler of the exhaust pipe may be conveniently utilized for heating the interior of the car. A further obj ect is to provide a heater which can be very quickly and easilyinstalled, and which may be installed without first removing or chang ing the mufiler, or in any way altering or disfiguring the car, except for the making of a hole in the floor board, through which the heater pipe is projected from the heater shell proper. Further and more specific 0bjects will be disclosed in the course of the following specification, reference being had to the accompanying drawing, in which:

Fig. 1 is a perspective view of the heater, before being secured in place.

Fig. 2 is a central sectional elevation through the heater and also showing parts of an automobile to which it is attached.

Fig. 3 is a front elevation of the heater shown in Fig. 1.

Referring to the drawing more particularly and by reference characters A designates the floor of a motor vehicle having a seat B, a muffler C, and the exhaust pipe D, which connects the muffler with'the exhaust manifold of the engine (not shown) all being of common and well known construction and arrangement. a

The heater consists primarily of a shell or sleeve 4, which surrounds the mufiler C and extends, with its front end, forwardly thereof. The shell is longitudinally split at its under side where ithas-two overlapping edges 5, so that it may be opened to dro over the pipe D, after which it is moved bac over the Inufiler, as shownin Fig. 2. The'rear end of the shell 4 is tightened about the rear end of the mufller shell, and is there secured by a clamping strap 6 having a bolt 7. Similarly the forward portion of the shell 4 is provided with a clamping strap 8 having a bolt 9. One of the flanges 5 has a lip 10, for engagement with the adjoining flange, and thus prevents the forward end of the shell from being clamped by 89, to

less than a predetermined diameter. The normal front end diameter of the heater shell is greater than the normal rear di ameter, with a result that the shell is rearwardly tapered, and provides a rearwardly tapering annular passage between itself and the mufiler, and this passage is utilized for the heating of the air, by the mufiler body, as it passes to the car body.- I

The substantially cylindrical portion of the heater, forward of the mufiier, isprovided with an'inclined deflector plate 11, which is elliptical, in plan, so to fit snugly in the embossed rim 12 of the shell. This plate is preferably made in two sections, secured together as at 13, so that it may be se cured over the pipe D without removing. the mufiler, and is ,of course provided with a central elliptic aperture 14, to accommodate the pipe l). Directly above the plate 11 the heater shell at is provided with an. opening up through the floor A of the car. The up per end of the pipe 16 is provided with a damper '17, of any common and well known construction, for regulating the quantity of warm air into the car. f v

The lower end of the deflector plate 11 is horizontally cut, as at 18, so as to provide a segmental opening 19, through which the incoming or cold air passes. Y

The construction and method of installing the heater should now be clear. The use or operation may be briefly described, as follows: As the car moves forward the cold air striking the deflector plate ll'is directed downwardly and rearwardly to the opening 19, and from it is swept rearwardly and about the muffler by which it becomes heated. It then passes forwardly and up through the pipe 16 and damper 17 to the interior of the car.

described my invention, what I claim to be new and desire to protect by Letters Patent is: i

. 1. A heater for a motor vehicle having an exhaust pipe and a muffier atthe rear endthereof, comprising a shell surrounding the muffler and extending forwardly thereof, an inclined deflector plate arranged within the forwardly extended portion of the heater shell and forn'iing with said shell a heating chamber, and having an air inlet at a rearward point into said chamber, and a pipe connecting the shell with the floor of the car,

2. A heater for a'motor vehicle having an exhaust pipe and a muliler at the rear end thereof, comprising a longitudinally split shell, a clamping band for securing the rear end of the shell about the rear end 01'' the mufller, the shell being Wider toward its other end so as to form a tapering annular passage between itself and the body of the mufiler, a deflector in said other end of the shell for directing incoming air into the lower end of the passage, and a pipe connecting the upper part of the shell with the body of the vehicle.

3. A heater for a motor vehicle having an exhaust pipe and a mulller at the rear end thereof, comprising a longitudinally split shell, a clan'iping band for securing one end of the shell about one end of the mulller, the shell being wider toward its other end so as to form a tapering annular passage between itself and the bod oi the mulllcr, a deflector in said other end of the shell for directing incoming air into the lower end of the pars sage, a second clamping band about an int ermediate portion oi the shell and being operative to assist in holding the deflector in place, and means for directing heated air from the shell into the vehicle.

4-. A. heater for a motor vehicle having an exhaust pipe and a mother at the rear end thereof, comprising a longitudinally split shell, a clamping band for securing one end of the shell about one end of the mulller, the shell being wider toward its other end so as to form a tapering restricted passage between itself and the body of the mullier, a deflector in said other end of the shell for directing incoming air into the lower end of the passage, a second clamping band for securing said deflector plate in the shell, and means for directing heated air from the shell into the vehicle, said shell having an elliptical groove For receiving the deflector plate.

5. A. heater for a motor vehicle having an exhaust pipe and a mutllcr at the rear end thereoi, comprising a longitudinally split shell, a clamping band for securing the rear end of the shell about the rear end of the mufller, the shell being wider toward its other end so as to form a tapering annular passage between itself and the body of the mulller, a deflector in said other end of the shell for directing incoming air into the lower end of the passage, and a pipe connecting the upper part of the shell with the body oi the vehicle, said deflector plate having an opening through which said incoming air may pass.

(3. A heater tor a motor vehicle having an exhaust pipe and a mulller at the rear end thereof, said heater comprising a tapered shell the rear portion of which surrounds the mulller so as to form an annular heating chamber thereabont, said shell extending beyond the forward end of said mulllcr to form an air passage, a deflector member in the forward end of the shell for directing air into the lower portion of the passage, and means for delivering heated air from the air passage into the vehicle, said deflector member having a central aperture for receiving the exhaust pipe.

7. A heater for a motor vehicle having an exhaust. pipe and a muiller at the rear end thereof, said heater comprising a tapered shell the rear portion oi which surrounds the mulller so as to form an annular heating chamber there-about, said shell extending beyond the forward end of said mother 10 lorm an air passage, a del'lector member in the forward end oi the shell for directing air into the lower portion ol the passage, and means for delivering heated air from the air passage into the vehicle, said deflector member being sectionally formed so as to facilitate securin it about the exhaust pipe.

8. A heater or the character described comprising a rearwardly tapering shell, the same being longitudinally split so as to be adjustable in diameter, a pair of clamping bands about the shell, an inclined deflector plate, having a central opening, secured in the forward end oi the shell, a warm air delivering pipe extending from the shell, directly above the deflector plate, said dctleetor having an opening at its rear end for the introduction of cold air into the heater shell.

In testimony whereof I aflix my signature.

GEORGE W, WHTPPS.
