This invention relates to heating devices in general, and more particularly to heating devices adapted for use on automobiles.

It is highly desirable in connection with il the manufacture and use of automobile heati l which may be conveniently assembled, which may be conveniently installed, and which is accessible for inspection, renewal, cleaning or repairing.

Other and further objects of this invention Y' 20 will be apparent as the same becomes better understood from an examination of the specification and claims in connection with the accompanying drawings, wherein- Fig. l is a fragmentary View, partly in w25 section, of an automobile provided with a heating system embodying this invention;

Fig. 2 is an enlarged fragmentary plan view of the heater;

Fig. 3 is a section taken on the line 3 3 80 of Fig. 2;

Fig. 4 is a section taken on the line 4 4 of Fig. 3;

Referring to the drawings more particu- 5 larly, reference character 8 designates the body of an automobile in the floor of the rear of which is secured a heater generally designated by the reference character 9. This heater is supplied by means of a pipe 11 con- 50 nected through the intermediary of a valve 1929. Serial No. 363,145.

12 to the exhaust pipe 13 leading from the engine of the automobile. This valve 12vmay be of any suitable type, but is preferably such as shown in Fig. 6 and comprises an elbow 14 in the form of a casting having an inlet 15 and an outlet 16. This casting 14 is strapped tothe exhaust pipe 13 with its inlet 15 opposite an opening 16 formed in said pipe. A valve plate 17 resting upon a shoulder 18 formedintegrally with the kcasting 14 in the inlet 15, is adapted to close said inlet and is secured upon a transverse shaft 19. This shaft 19 is provided outside of the casing 14 with an operating arm 21, which may be actuated to swing the plate 17 to open position, shown in dotted lines in Fig. 6, whereby eXhaust gases from the engine may be admitted to the casing 14 and the pipe 11 leading to the heater. The front end of the pipe V11 is secured in the outlet 16 of the casing 14 by means of a set screw 22 provided with a locknut ,23.

A link bar 24 hinged at its lower end to the arm 21 is flanged atits upper end and threaded to a rod 25. This rod 25 extends through the floor of the automobile and is provided with a manually operable knob 26 in position to be conveniently operated by the driver for adjusting the valve plate 17 to open or closed position, or any intermediate position depending upon the amount of heat desired. A threaded member 27 is also provided on the rod 25 and a spring 28 interposed between said member and a supporting plate 29 for Jche knob 26 imposes sufficient pressure on said member 27 to cause sufficient resistance to the turning of said rod whereby the same will not move from adjusted position on account of the vibration of the automobile.

rThe heater 9 comprises an elongated annular member 31 outwardly flanged at its upper edge, as at .32, whereby itmay be suspended from the Hoor of the automobile, and inwardly flanged as at 33 on its lower edge to retain the parts hereinafter described which constitute the heating element of the heater.

A shell 34 in the form of an inverted channel member closed at its ends forms a partition within the heater 9, the lower side of which comes in contact with the exhaust gases from the engine and the upper side of which comes in contact with the air within the member 31. The lower side of the channel member or shell 34 is closed by a plate 35, a layer 36 of asbestos, or other heat insulation material, and a second plate 37. The plate 35 is provided with a plurality of longitudinally spaced upwardly struck aligned integral bafies 38 and 38 and the plate 37 acts to reenforce said lirst plate. These battles are provided with openings 39 tor the passage ofthe exhaust gases which are admitted through an inlet opening 4l at one end of the heater and which are discharged through an outlet .opening 42 at the other end of the heater.

The bailles 38 are each provided with a recess 43 at their respective upper peripheries and extend in close proximity to the inner walls of the shell 34 whereby a substantial proportion of the gases are caused to flow in relatively close proximity to the upper wall of said shell in the vicinity ot said recess.

The opening 41 is provided with a threaded deflector member 44 for receiving the pipe l1 and which extends through the plate 37 and the insulation material 36, and is provided with a hollow elbow or guide portion 40 which is situated in an aperture formed in the plate 35 by the upwardly struck battle 38 and which extends above the plate 35 with its delivery end spaced just suflicient close to said baiie to allow the desired portion of the gases to escape between said end and bale and pass around the periphery of the baiiie while the remainder of the gases pass through the opening 39. In this connection attention is invited to the fact that battle 38 is shaped differently from the bai'lies 38 in that the major portion of its periphery is spaced from the wall of the shell 34. In addition to apportioning the amount of gases desired to flow along the upper inner periphery of shell 34 and the amount desired to flow through the openings 39, the member 44 acts to prevent errosion of the shell by the relatively highly heated gases admitted to the inlet of the heater. The bailie 38a thus cooperates with the member 44 to restrictthe flow of gases into the shell and to distribute said iow thereby acting to some extent as both a safety valve or reducing valve and a distributing valve arrangement for the gases. A threaded member 45 without the elbow or guide is provided in the opening 42 for an outlet pipe 46.

An upwardly dished cover 47 is hinged by means of hinges 48 to the top of the member 3l and forms an air chamber with the inner walls of said member and the upper side of the shell 34. This air chamber is heated by radiation from the shell 34 and the heated air is adapted to circulate through openings 49 in the cover 47 to the interior of the automobile.

In manufacturing the heater, the plates 35 and 37 are assembled with the intervening layer 36 ot insulation material and are secured in position with respect to the shell 34 by means of a bead or flange 5l formed along the edges of the latter. These parts 34- to 37, inclusive, are thus self-contained and may be conveniently attached to the member 3l by insertion from the top thereof and retained by beads 59 one on either side of said member for holding said parts against the flange 33.

The cover 47 being hinged to the heater body, access to the interior thereof may readily be obtained for insi'iection and cleaning, and even for removing the self-contained parts 35 to 37, inclusive, by merely springing the side walls of the member 3l outwardly to release said parts from the beads 52.

By causing a si'lbstantial proportion of the. exhaust gases to flow through the recesses 43 in close proximity to the upper wall otl the shell 34, which is relatively close to the top of the heater, increased eiiiciency thereof is obtained.

Other advantages will be apparent without further description.
