EXHAUST-HEATER FITTING FOR MOTOR-PROPELLED VEHICLES.

To all whom it may concern:

Be it known that I, CLYDE Sr PELTON, a citizen of the United States, residing at Cleveland Heights, in the county of Guyahoga and State ofOhio. have invented a certain new and useful Improvement 111 Exhaust-Heater Fittings for Motor-Propelled Vehicles, (Case G,) of which the following is a full, clear, and exact description, reference being had to the accompanying draw- Tly invention relates to motor driven vehicles and es ecially to vehicles driven by internal com ustion engines. More articularly my invention relates to the taklng and the control of the exhaust gases from engines of this type for the purpose of heat- 1n the tonneau of the vehicle.

%)ne object of my invention is the provision of means for taking exhaust gases simultaneously from two or more exhaust pipes leading from the propelling engine whereby both or all of the pipes may be caused to supplly a heater located in the vehicle body. e exhaust pipes may lead from a single engine unit or from the engines of a twin set. In the application to a vehicle drivenv by a twin engine unit, my 1nvention has an additional and particular advantage in that the heating gases are taken from each engine of the twin engine unit in such a manner that the back pressures remain substantially the same on the two engines and aperfect balance is maintained between them. In carrying out my invention the two or more exhaust pipes are caused to lead into a common member and the exhaust ases for. heating purposes are deflected 30m the, common exhaust member past the mullier to the radiator, the exhaust pipes between" the --en e and the member being symmetrical y arranged with reference thereto to insure equal reslstances 1n the exhaust circuits More articularly still the exhaust pipes are paral el arranged and dis posed in close proximity to each other, and the common exhaust member has passages registering at one end with the exhaust pipes and converging together at the other end into a single passage, the exhaust gases for heating purposes being taken from the sin le passage.

l or a better understanding of the above enumerated advantages of my invention relatively to each other and when the Specification of Letters Patent. P t Jam 1921 Application filed March 24, 1917.

Serial No. 157,243.

and of others which will appear hereinafter, reference maybe had to the drawings accompanylng this specification, Figure 1 of which is a side view, with certain parts broken awa-y, of a mufiier with connections to engine and attachments tothe vehicle floor; Fig. 2 is an enlarged sectional view of the devices illustrated in Fi 1; Fig. 3 is an enlarged plan view thereo The drawings illustrate a mufller and attachments for use with either a single engine unit or a twin engine, the propelling engine unit not being illustrated. The two ex aust pipes from the engine are parallel arrangedand lead. to inlets 1 of the exhaust recelvlng member 2 which member serves also as the head of the muffler 3. As set forth more particularly in my application filed on even date herewith, the head 2 is provided with an opening 4 on the top theresistances in their passage to the central passage of the head 2. Since the exhaust gases encounter substantially equal resistances in the exhaust circuits the back pressures in the pipes remain substantially unchanged propelling engine is a twin unit the balance between the two engines is therefore unimpaired. The attachment 5 is preferably a special fitting devised by me and covered in the above noted application which is adapted to be substituted for the plate covering the opening when the heating system is to be installed. This attachment comprises a disk valve 6 mounted for rocking movement on an axis passing through the plane of the disk, and this disk is adapted to project down into the central passage of the head 2 toward the engine unit and thereby deflect a portion of the exhaust gases out throu h the branch fitting 5 to a radiator located in the tonneau of the Vehicle. The branch fitting 5 has a flexible pipeconnection 7 leady illustrated in Fig. '1.

I The mufller shown in these drawings comprises an outer cylindrical casin a central smaller tube 8 located therein an communicating with the central passage in the head 2, and an intermediate tube 9 located between the two. The tubes 8 and 9 are formed with perforations at opposite ends 10 interposed between one side of the tube 9 and the outer casing. I have here shown a second flexible tube 11 controlled by a valve 12 leading from the tube 8 to a second heater 13 also located above the car floor. Both heaters are illustrated as provided with discharge fittings 15.

While I have set forth my invention in the specific manner required by the patent statutes it is understood that the claims hereto attached are intended to cover the various forms my invention is capable of assuming, and are not to be limited in'scope except as is required by the prior art.

Having thus described my invention, what I claim is:

1. In a vehicle propelled by an internal combustion engine, the combination with two exhaust pipes leading from said engine, of a fitting having a single passageway with which both pipes communicate, the wall of said passageway being formed with an open-- ing symmetrically arranged with reference a to said pipes and adapted to receive a branch connectlon leading to a heater.

2. In a vehicle propelled by an internal combustion engine, the combination with two exhaust pipes, of-a fitting having a single passageway w1th which both pipes communicate, thewall of said passageway being formed with an opening symmetrically arranged with reference to said pipes a branch fitting connected to said first fitting and communicating with said opening, and a valve in said branch fitting having a part adapted and arranged to obstruct the passage through said first fitting when the valve is opened and so deflect gases into said branch.

3. An exhaust fitting for engine propelled vehicles comprising a member having a single passageway for communicating with a to the radiator connection on the floor lateral opening communicatin gsmgle passageway and surroun ed by a fiat ,flange whose'plane is parallel to the plane mufiler and a pair of diver g passageways terminatin in sockets or the reception of twin e aust pi es, said passage ways being symmetrical y arranged with reference to said members whereby the back pressure in said exhaust pipes are maintained substantially the same, said member having an opening in its side, and a branch fitting adapted to be secured to said opening comprising a valve for deflecting a porn tion of the gases from said member.

',4. In a vehicle pro elled by an internal combustion engine, tie combination with two exhaust pipes, of a common 'member to which said plpes are connected, said member having an opening in its side symmetrically arranged with reference to said ipes whereby back pressures onvsaid engine are maintained substantially the same, and a branch fitting adapted to be secured to said opening comprising a valve for deflecting a part of the gases from said member for the purpose described.

5. An exhaust fitting for engine propelled I vehicles, comprising a member having a single passageway for communication with a muffler and a pair of diverging passageways terminating in sockets for the reception of twin exhaust pipes, said member having a with said which includes the axes of both pipes and whose face forms a seat adapted to receive a platewhereby the opening may be closed or a branch fitting communicating with the opening. v

6. An exhaust fitting for en ine propelled vehicle comprising a member aving a pair of converging passageways mer ing with a single passageway, said mem r having means whereby twin exhaust pipes can be secured thereto in communication with said converging passageways respectively, and other means whereby said single passa eway can be placed in communication with-t e interior of a muffler, and the wall of said single passageway being formed with an openmg symmetrically arranged with respect to said converging passagewa s.

In testimony whereof, I ereunto afiix my signature.
