AUTOMOBILE-HEATER.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed December 13, 1920. Serial No. 430,396.

T 0 all whom it may concern:

Be it known that 1, LnsLIE C. MILNER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Automobile-Heaters, of which the following is aspecification.

The object of this invention is to collect the heat radiating from the exhaust manifold of an automobile and discharge it by the advance movement of the car and drive of the radiator fan back into the car to warm the passengers.

A further object is to provide means for installation and assembly in many cars of the present popular design without cutting passageways especially for it, and to provide easy, quick, and simple means'for installing the device in cars already in use or made.

I accomplish the above, and otherobjects which will hereinafter appear, by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a view in side elevation of my invention and the associated parts of an automobile in which it is shown assembled. Fig. 2 is a top plan view of the invention detached from the car. Fig. 3 is an end elevation looking toward the rear of the car.

respective opposite directions from the dotted line 4-4, 54-5 of Fig. 2.

Like characters of reference indicate like parts in the several views of the drawing.

In the drawing, 6' are the engine cylinders, 7 the exhaust manifold, 8 the fan which draws atmospheric air in through the radiator (not shown) and discharges it rearwardly longitudinally of the exhaust manifold, 9 is the dash, 10 the coil box supported by the dash and 11 is the floor of the body of the car. In some of the most popular cars the dash extends over the adjacent end of the engine and a dished metal segment 12 completes the closure between the interior of the ca body and the indent in it for the engine. This segment has a flange with holes for screws by which it is easily removed, and when removed it provides the necessary opening into the body of the car from in front where the manifold is located. By cutting away a portion of the segment plate 12 in the .vertical plane of the exhaust manifold there is sufiicient room for the passage into the car of a hood conveying heat radiated from the exhaust manifold. This hood is in two transversely divided parts 13 and 14. The part 13 is open at the bottom for its entire length to receive the manifold by being pushed down over it. Its lower edges when it is in place are substantially horizontal, but the roof which is semicircular in cross section slopes from the end next the fan upwardly toward plate 12 in order to pass into the car body and to help the airflow. The sides of 13 are substantially parallel, the one next to the engine being somewhat shorterthan the outer one because of the glands from the engine cylinders to the exhaust manifold upon which this side rests. The lower edge of the outer side of the part 13 is turned in to form a stiffening flange 15 and riveted to theinner wall of this side are the depending ears 16, 16, which are clamped under the adjacent members 17 of the engine. The end of the part 13 is flared outwardly at 18 to form a funnel the better to collect air driven backby the fan 8, and rearwardly sloping finsor b'ailie plates 18 are provided in the upper portions of the part 13 to increase the distance of travel of the ai in contact with the hotmanifold and to more completely i nix the hot and cold air.

The part 14 of the hood is high enough to receive the expanded rear end of 13 and form a dead air pocket over the downwardly bent discharge end of the exhaust manifold. and its tapering walls are closed at the lower as well as lateral and top portions to form a dead-air pocket and to direct the heated current of air to its discharge at its rear through the segment plate 12. The member 13 extends rearwardly of and below the exhaust manifold 7 into contact with the downwardly bent discharge end of the latter to increase the size of the dead air pocket.

The end of part 13 is madeoblique at 19 to correspond with andcontact the sloping bottom of part 14 as clearly shown in Fig. 5.

A receptacle 19, here shown as cylindrical but which may be suitably formed-in other shapes is fastened by suitable means, here shown as screws 20, 20, to the segment plate 12, and may be removably secured as shown, to allow of disconnectionin shipping, and the like. The wall of the receptacle next to the plate'12 has an opening through which the small end of part 14 discharges into the interior of the receptacle. A joint is preferably made here by. forming a series ceptacle wall that would be otherwise cut away, and bending them out and inside of the part 14 where their contact with the walls of the latter makes the joint more secure. This joint may be made still more secure by soldering on the outside. The receptacle is long enough to afford. ample distribution of the hot air inside the car and for the discharge of the air a horizontal series of holes is provided which is closed by asliding damper-plate 23, having registering holes that may be brought opposite the holes in the receptacle wall when it is desired to discharge hot air into the car.

In practice I have found it more convenient to the user to furnish the device with segment plate 12 already cut and attached so all he will have to do is to remove the original plate that comes with the car and replace it with the new one with my device fitted and attached to it. VThis is done with the -part 13 detached after which the assemarms 17.

bly is completed by slipping part 13 into place and clamping the ears 16 under The fins 18 may be omitted in tion what I claim as new and wish to secure by Letters Patent of the United States, is

1. In an auto-car, the combination with a )assen er bod and an internal combustion engine having an exhaust manifold, said engine and manifold being located outside of the body, of a heat distributing receptacle located within the body, damper means inthe wall of the receptacle, and a hood in two separable parts one of which discharges into the heat distributing receptacle and extends to the adjacentend of the manifold and the other part of which extends formost cases 1n climates where great severity of weather wardly fromthe first part and envelops the top and sides of the manifold.

2. In an auto-car, the combination with a passenger body, an internal combustion engine in a compartment in front of the body separated therefrom by a partition, and a hood discharging heat from the engine compartment into the body, of a plate forming part of said partition between the body and said I engine compartment through which plate the hood passes and to which plate the hood is fastened.

3. In an auto-car, the combination of a body, an internal combustion engine in a compartment in front of the body, a plate closure between the body and engine compartment, a heat distributing receptacle within the bodyremovably secured to the plate, and a hood discharging the heated air from the engine compartment into the receptacle. I, 4. In an auto-ca the combination of a body, an internal combustion engine in a compartment in front of the body, a plate closure between the body and engine compartment, a heat distributing receptacle within the body removably secured to the plate, and a hood discharging the heated air from the engine compartment into the receptacle, said hood being in a plurality of parts connected by'telescopic joints.

5. In a heater for automobiles, the combination with a body of an internal combustion engine having an exhaust manifold, a heat distributing receptacle in said body, and a hood in two parts one of which parts is fas tened to the distributing receptacle and the other of which parts is connected with the first part and also surrounds the top and sides of the exhaust manifold, said hood being separable into its parts adjacent that end of the exhaust manifold which is nearest the receptacle.

I LESLIE C. MILNER.
