same, reference being had to the accompanying drawings, and td'the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates broadly to the class of heating devices for automobiles and further contemplates the provision of a device of this character which is simple in construetion, strong, durable and eflicient in operation and one which can be manufactured and. placed upon the market at a minimum cost. 7

By using the exhaust gases from the engine as a heating medium it is apparent that the cost of operation of the device reduces -it to a minimum and that its provision upon ..a vehicle will not cost any great expense to the owner thereof. It will also beapparent from'the hereinafter ap caring description that my device will so e the subsidiary function of a mufiier, it receiving directly tihe exhaust gases from the engines cyliners. a While I'have designated in the drawings suitable exhaust gas passages and suitable water passages, it is to be realized that water may be introdu'ced through the gas pas- J sages and. the gases through the water pas- 40 sages if such occasion presented itself.

', With the above and other objects in view' my invention consists in such details of construction and in the varrangement and combination of parts as will be hereinafter more fully described and specifically pointed out in the appended claim. In desc" 'bing my invention in detail reference will behad to, the accompanying drawings wherein like characters denote like or corresponding parts'throughout the several views, andin which 2 I Figure 1 isa perspective view of my invention; Fig v 2' is a; sectional view oniline 22 of Fig. 3, and Fig. 3 is a sectional yiew on line 33 of Fig. 2. 1 Reference now'bein'g-had to the details of respectively inner and outer concentrically arranged cylinders spaced apart from each other and intermediate thesame are lugs 16. Each end .ofthe outer cylinder is provided with an opening, one being an inlet opening through which a pipe 20 passes and the other an outlet opening from whichan exit p pe 25 leads. Said outer cylinder is provlded with acircumferential covering 15 of insulating material, and about the latter s a covering of metal 15". Theinner cylinder 14 is provided with a transverse partition 1'8near one end soas to, form a chamber 18 Said partition is perforated for the reception of the open ended fiues 19, which at their opposite ends are mounted in perforations in one end of the inner cylinder..

jacent ends of the inner and outer cylinders,

asshown in Fi s. 1 and 20f the drawings. It will be note that the ends of the tubes 19 are open and are adapted to receive exhaust gases which are conducted through the pipe 20 to the chamber 18 formed intermediate the perforated partition engaged by said pipes 19, and the adjacent end of the inner drum. A pipe 39 passes through the wall of the outer cylinder and eommunicates with theinterior of the inner drum. Water, which is preferably driven by a pump, is

.forced through the pipe 13 into the interior of. the shell 14 and becomes heated by contact with the flues 19 and makes exit through the pipe 39 leadinfrom the upper portion of the shell 14 an" through the wall of theshell15. i m

The hotwater, after passing from the shell 14, passes through ipe.19 by the valve 40, pipes 38, 33 34: an 35, thence by the union 37 and the pipe 36, thence through the union 37 and pipes 33, 34; and 35, through the elbow 32 and pipe 28, through thevalve to the connection 27 and through the pipe 26 back to the pump, thus making a comlete circuitl The gases, after g1ving ofi heat by radiation, make exit throu h the passageway 25 to the atmosphere. f funchamber 30, regulated by the valve 29, thence ml 29 communicates with the yalvecham ber 30, regulated by the Valve 29. The

Valve 29 serves to regulate the flow of water through the pipe 28 and a-suitable faucet 31 is fitted to the pipe 28 through which Water may be drawn from the latter. A pump 12 is mounted upon the shaft 7 in suitable bearings upon the depending bars 3 which are fastened to the frame 1 and a gear wheel 12', driven by a gear wheel 11 fixed to the shaft 6- upon the hanger 3, fastened to the frame. The shaft 6 has a bev- ,eled wheel 10 in-meshwith the gear wheel 9 upon the shaft 8, whereby power is supplied to operate the pum What I claim to be ne izv is In combination with an outer and an inner cylinder, lugs intermediate the-cylinders and spacing the same apart, an apertured partition in the inner cylinder, a pipe passing through the aperture in said partition and through one end of both the inner and the outer cylinders, a series of.openended fiues positioned within the inner cylinder and extending through apertures formed in one end of the latter and the partition therein, a'partition within the outer cylinder having a central opening, a baffle plate within the outer cylinder adjacent to its end spaced apart therefrom, an exit pipe leading from the end of the cylinder adjacent to the baflle plate, and an inlet pipe and an outlet pipe, each communicating with the inner cylinder, as shown and de scribed.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
