CONSOLIDATED CAR-HEATING COMPANY, INC., ALBANY, NEW YORK, A. CORPO- BATION OF NEW YORK BUS HEATING srs'rmu Application filed February 2, 1926. Serial No. 85,500.

The invention'will'be hereinafter fully set forth and particularly pointed out in the claims.

My invention is shown diagrammatically in the accompanying drawing.

My invention relates to means for heating vehicles, particularly busses, which are equipped with hydrocarbon engines. The source ofv heat which I employ is that derived from the re-combustion of the exhaust from the aforesaid engine, and, in the present case,

- I utilize that heat in asteamboiler wherefrom steam pipes convey the steam to suitable radiators on both the lower and upper decks of a bus, or other place Where heat is desired in a railway car, boat or other vehicle.

Referring to the drawing, R represents the body of avehicle to be heated. A represents the'exhaust manifold of a hydrocarbon engine of the internal combustlon type and B the exhaust pipe leading therefrom and terminating at b in a suitable nozzle for deter- ..mining the velocity of the outflow. C is a sleeve surrounding tube B but of larger diameter into which atmospheric air is drawn for the re-combustion. The sleeve 0 is continued by a tube D which is closed at its left end, but-is perforated by a multiplicity of holes which give the effect of a wire screen,

permitting the outflow of (gas but preventing the entry of the flame.

at its right, while outside of the tubes D and E is the casing F from the left end of which the hot gases emerge throu h the tube H. In

.- operation the exhaust which supplies fuel for the burner I divert them from pipe H into utside of tube D 1s a baflie tube E closed at its left end but open a branch pipe S, from which I pass them into the flues of a tubular boiler J. After the heat has been abstracted by the water in the boiler the waste products pass by pipe V into the final exhaust pipe W. At the junction of pipes H and S I place a damper K by means of which the products may be diverted wholly or partlyinto pifie S or the exhaust pipe W; This damper may be manually controlled by a lever 1 on the instrument board/of the vehicle, but in the event of an undesired steam pressure in the boiler a diaphragm located within a diaphragm chamber L subject to the steam pressure acts through lever P to close damper K against pipe S, as

shown by dotted lines, thereby diverting the 7 hot productsfrom the boiler and into the exhaust pipe W. While the damper may be operated by the hand leyer K independently of diaphragm L, so long as the diaphragm is more or less inactive, the full force of the steam upon the diaphragm will close the damper by moving the hand-lever backwards. By this means the boiler is adequately protected against surplus pressure, although an ordinary safety-valve N may be added if desired/ From boiler J a steam pipe 0 rises from which branch pipe 0 may go to the heat-distributing radiators on the lower deck of the vehicle and, if desired, a second pipe 0 may. lead to similar radiators on the upper deck. Both 0 and 0 will drain back into the boiler. v

What I claim as new and desire to secure by Letters Patent is:

1. In a heating system, the. combination with a boiler provided with a heating chamber, and a radiator located in the space to be heated and connected with said boiler, ofa device for reburning exhaust gases of an internal combustion engine, an exhaust pipe for said reburned gases, a duct joining said exhaust pipe and leading to the heating chamber of said boiler, a damper located at the junction of the duct with the exhaust pipe to selectively control delivery of reburned gases to said boiler or to said exhaust pipe, and means connected with the boiler for actuating said damper.

2. In a heating system, the combination with a boiler provided with a heating chamber, and a radiator located in the space to be heated and connected with said boiler, of a device for reburning exhaust gases of an internal combustion engine, an exhaust pipe for said reburned gases, a duct joining said exhaust pipe and leading 'to the heating chamber of said boiler,- a damper located at the junction of the duct with the exhaust pipe to selectively control delivery of reburned gases to said heating chamber or to said exhaust pipe, means connected with the boiler for actuating said damper, and

means for manually operating said damper independently of the first mentioned actuating means.

3. In a heating system, the combination withra boiler provided with a heating cham- 'ber and a steam generating chamber, and

a radiator located in the space to be heated and connected with said steam generating vchamber; of a device for reburning exhaust" gases of an internal combustion engine, an exhaust pipe for said reb'urned gases, a duct leading from said exhaust pipe to the heating chamber of said boiler, a damper located at the junction of said duct with the exhaust pipe to selectively control delivery of reburned gases to either, and meanscontrolled by the pressure in said steam generating chamber .for automatically damper. p v
