Original application filed March 24,1917, Serial f lo. 157,23. mvidec'l and this application filed Hay 8,

1920. serial W0. amaze. v

To all wfiom it may mnceru Be it known that It, CLYDE S. PsLroN, a citizen of the l nited States, residing at Cleveland Heights. in the county'of Cuyahogs and State ofOliio; have invented a certain new and useful Improvement in Heaters for Motor-Propelled Vehicles, of

which (he following is a full, clear, and exact description, reference being had to the ac- 0 companying drawings.

This invention relates to motor propelled vehicles, and particularly to the heating of the same by the use of the exhaust gases from the engine which drives the same. The 15 objects of the invention are the provision of a new mode of attaching the heating device tolhe exhaust system; the provision of improved and simplified means for attaching a heater to the rearward end of the vehicle; the provision of means for attaching" the heater directly to the muil'ler in which the exhaust is silenced: While further objects and advantages of ,the invention will be come apparent as the description proceeds. This application, is a division of my earlier application No. 157.243., filed Iilar. 24, 191?.

In the drawings accompanying and form ing a part of this application. Fig. 1 is a side view with certain partsbrolzen away of a nnu'iler with connections to the engine and attachments to the heater; Fig. 2 is an enlarged sectional view of the parts constitulb in; the rearward. end of the muiller; and Fig. 3 is an enlarged plan view of the parts shown iii Fig.2.

Describing the parts by reference characters, the mulller here shown comprises an outer cylindrical casing 1 having and fittings Q-3 secured thereto. The end fitting 2 has a central hub 4 which receives the exhaust pipe 5 leading; from the internal combustion engine (not shown), The end fitting 3 is also provided with a central hub 6 for the reception of the flexible pipe 7 leading to the heater 8 which is carried by the vehicle fioor 9. Running from end to end of the mufller inside the casing 1 is a central tube 10 which communicates directly With the hubs 47 and'6; and likewise secured tothe heads is the longitudinal tube 11 which surrounds the tube 10 but eccentric thereto, so as to leave an increased space 12 adjacent the lower wall of the casing. Ca 1'- ried by the rearward head 3 and projecting a considerable distance into this space is the discharge pipe 13.

The forward end of the tube 10 is formed with a plurality of perforations 15 for the escape of the combustion products as is likewise the rearward end of the tube 11, thus affording not only a sinuous path for the combustion products, but also an air cushion at the rearward end of the tube 10 by Which the impulses received through the pipe 5 are absorbed. By attaching the vehicle this pipe,- the gases are obtained at their maximum temperature, the inertia of their movement tends to force them the more positively into the heater, while the proximity of the muffler to the rearward end of the car enables the attachment of the heater With the smallest possible amount of piping 7.

there is formed between. the hub 6 and tube 7 a valve chamber 16 in which is mounted the butterfly valve 17 carried by the spindle 18 operated by the handle 19, this valve being shown open in full lines and closed by dotted lines in Fig. llhen the valve is closed. the nmiller operates in the same man nor as the usual type of niutller in which the rearward head is formed without any central opening; When the valve is opened the action of the muffler is improved by reason of the decrease of back pressure consequent upon opening another outlet for the gas. The gas escaping through this new passage is cooled and silenced b is of any suitable or desired type.

It will he understood that I do not restrict myself to any particular type of mufiler or to any {articular type or arrangement of controlling valve, or to any other particular feature except as recited in my claims.

Having thus described my invention, hat I claim is; v
