i I Application filed July 22,
, declare the following to be a full, clear, and
. automobile of standard construction.
exactj description of the invention, such as willenable others skilled in the art to which it a pertains to make and use the same.
Edy-invention has for its object to rovide a simple and efiicient hot air heater for automobiles whichutilizes the waste gas of the exhaust of the engine; and to such ends, generally stated, the invention consists of the novel construction and combination of parts hereinafter described and defined in the. claims. a r The inventiomas applied to automobiles, is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views- Referring to the 'drawings'; v 4\ Figure, 1 is; a side elevation with some parts broken away and some parts sectioned, showing my improved heater applied to an 1F ig. 2 is a view partly in plan and partly in'horizontal section on the line 2-2 of Fig. '1, showing the heater and the' main and branchexhaust pipes; 1 7 .Fig. 3 is a perspective partly in full and partly in section, showing the heater and illustrating the manner in which it is applied to the floor ofthe automobile;
Fig. 4; isa horizontal section'through the heater approximately on the line 4-4 of Fig.3;and
Fig. 5 isa view correspond ng to Fig. ,1 but illustrating a slightly modified form of theheater. v
Of the parts of the automobile it is only desirable for the purposes of this case to particularly note the automobile body 6, the floor 6 thereof, the internal'combustion en'- gine 7 exhaust pipe 8 and mufiler 9.
The heater shown iii Figs. 1 to 4, inclusive, is a rectangular structure made up of a box-like outer shell 10 closed at its bottom but open at its top and formed with outturned flanges. 11 secured by nut-equipped bolts or screws 12 to the floor 6*, said floor being provided with a large rectangular opening 13 of the size of the interior of the spaced Specificationof Letters I atent. Pafiented Deg, 20, 1921.

said outer shell. This opening 13 is covered by an open grate or. perforated plate 14.
which will prevent the lap robe or any other article of any considerable size from dropping into the casing 10. The casing 10 is set With'its sides at angles of forty-five degrees to the longitudinal and transverse axes of the automobile body, and in its front sides, near its closed bottom, itis provided with air intake ports 15.
Located Within the outer casing 10 and from the bottom and sides thereof and from theregister plate 14, is a box-like rectangular inner shell'16 through which rectangular hot air tubes -17 are passed. The;
The sections 18 of abranch exhaust pipe are extendedthrough openings in the front and rear corners of the shell 10 and are welded, or otherwise secured to the margins of the correspondingly formed holes in the front and rear corners of the shell '16. The
ends of the branch exhaust pipe 18 are coupled into the main exhaust pipe 8 by means of Y couplings 19. Aswitch valve 20 (see Fig. 2) is preferably placed in the front V coupling 19 and provided with anextended lever or hand piece 21 shown only in Fig.
1, by means of which said valve may be set inthe position shown in Fig. 2, so. as to throw the exhaust through the heater, ormay be set into a position to cut out the heater and throw the exhaust entirely through the main exhaust pipe.
It is important to note that the rectangular lines 17, as well as the sides of the easing 10 and shell 16 are setobliquely to the line of travel of them'achine and to the sides thereof, and moreover, that the said fines are staggered so that the hot exhaust gases between the front channels will be deflected against the angular corners of the rear flues.
By this arrangement, therefore,-the exhaust gases are deflected back and forth and caused to come into contact with all of the surfaces of all of the fines, as well as into contact with the four Walls, top and bottom of the inner shell 16. This combined with theway in which the outer shell 16 is spaced either through said Y pipe 19 will form theouter casing 10, gives ,a maximum heating eiiicienoy- The air drawn in through the ports 15 will, in part, be drawn through the fines, and in part circulated upward through the space between the shell 10 and casing 16, and thus the air will be heated before it is delivered into the car. Moreover, it is important to note that the air intake ports 15 have less cross section, and hence, less air conducting capacity than the fines and air passages through the heater. This prevents the cold air from being drawn too rapidly into the heater and retards the flow of air long enough to insure proper heating thereof before it is introduced'into'the car.
The outer casingand heater shown in lFig. 5 are like that previously described, except that they are elongated so as to provide a large number of rectangular flues 17 and so as to form theouter shell 10 with parallel side portions 10 and the inner shell 16 with side walls 16 having i -shaped indentations 16 lln this arrangement, an exhaust bypipe 19 connects the two direct pipe sections 18; and a pivoted valve 20' is provided for directing the hotexhaust gas, at will, or through the inner shell of the heater. heatershown in Fig. 5 will work like the heater shown in the other views, except that it will have more heating capacity and is, therefore, better adapted for large oars.
Obviously, a heater of the kind described.
may be cheaply made and very easily installed in a car already in use. its application requires simply cutting a hole in the floor of a car-and applying, in the main exhaust pipe, the coupling for the branch exhaust pipe of the heater which is to be attached.
