INTERNAL-COMBUSTION ENGINE.

"To all whom it may concern:

Be it known that 1, JOHN Goon, citizen o'f the United States, residing in Brooklyn,

New York, have'in'vented the following described Improvements in InternalrQombustion Engines.

The invention provides a simple means'of,

pendent combustion, and maintain when.

necessary, a proper working temperature in the crank case and cylinder walls of an tomotiveengines, thereby permitting the enine to be readily cranked and started even r in the coldest weather'and without danger of breaking the oil or'water pump if frozen, at the same time serving to eliminate or revent contamination of the lubricating oil 1n the crank case by liquid fuel escaping past the piston rings, and thereby also insuring prompt distribution of thelubricating oil to all the bearings of the engine.

In the accompanying drawings,

an engine as is necessary to comprehend the inventiomwith a diagram of the burner connections for the purposes stated;

Fig. 2 is a partial cross-section of the engine; and

Fig. 3 a-horizontal section on line IIIIII of Fig. 2. 6

These drawings represent a, conventional automobile engine of four cylinders, cast in block and formed with a flame pipe or passage 1, extending from a coupling flange at one end of the block along the side of the block through the several water-jacket spaces of the several cylinders, around the end of the block and back through the jacket spaces on the opposite side to an ofi'- takef'pipe 2 which may be extended to the engine exhaust pipe or elsewhere, preferably outside the engine compartment. Flame and hot combustion products are delivered into this pipe through a fitting 3 from an enclosed urner 4, operated in the present case by a fan 5, the latter being driven by a motor 6 connected to the starting battery and controlled by a switch 7.

'7 [the regulable connection 8, from the float bowl: of the engine carburetor 9, and a spark plug 10*in proper circuit with the Fig. 1 is a side elevation of so much of Application filed May 9, 1919, Serial No. 295,952.

battery and a spark coil 11 serve automatically to ignite the fuel in the enclosed burner whenever the switch is closed to start the fan'motor in operation. Such burnei s as herein shown are known to the art and any suitable type of enclosed mechanism, operated by forced draft or by suction may be used in its stead. When the burner head 4: is in action, flame or combustion products therefrom traversing pipe 1, heat the Water in the jacket space 'or spaces and thereby quickly produce a Working temperature therein. passage 1 can be incorporated in or associated with the jacket structure in a variety of different Ways, to transmit heat to the water therein'or otherwise heat the cylinder wall adjacent the combustion space.

A second passage 12 extends from the fitting 3 alongside of and around the barrels of the several cylinders below their combustion spaces or water-jackets, being substantially parallel to the pipe 1, with anoutlet on the opposite side into the same ofitake pipe 2. A portion of the. flame and combustion products from the burner mechanism traversing this passage heats the cylinder barrels and serves the double function of softening thev lubricating oil on the inner surfaces thereof in cold weather, which establishes a normal condition of lubrication. As in the case of the pipe 1, this passage may also be variously incorporated in or applied to the cylinder structure for the purposes stated.

Still another passage 13 extends from the fitting 3 downwardly around the lower side of the crank case, surrounding the chamber of the oil pump 14 and extending thence under the bottom of the crank case and upwardly on the other side to a connection 18 with the ofl'take 2 as in the case of the other It is obvious that the,

is therefore not likely to be broken thesame way the water pump, being located close to the jacket (but not'herein shown) is similarly protected. 1

- All the passages are desirably made of thin walls and pass through or inheating relation to the engine structure without interfering with other engine parts. 0 e or more of them may be omitted according to the effects required and the fittin 3 may have any desired shape accor ing to the selected location of the burner mechanism, regard being had to the proper distribution of the flame into each passage when a single burner is used to supply themall with flame or combustion products. No attempt is made in the accompanying drawings to illustrate any preferred location of the burner mechanism, controlled by the general designpf the power plant as a whole. which will vary widely in different cases. The cont-rolling switch 7 is preferably located within convenient reach, of the operator so that on such occa-' sions as the engine, may require it the supplemental source'of heat can be brought into action and. used for as long as may be neces-' sary to produce the results desiredf Such? switch may obviously be thermostatically controlledin. any usual manner. Valves 16 and 17 are provided in the fitting 3 so that all of the flame may be delivered to eitherpassage. These valves are indicated in dotted lines in Fig. 1 and are equipped with appropriate exterior crank connections where by they may be set to appropriate positions for controlling the entrance for the flame or combustion products to the passages, as will be understood without description, and it will be plain that all or apredominating part of the entire flame from a single burner may if desired be sent through any passage,

, a the cylinder combustion space as this is obviously' whether the engine be running or not, by a proper setting of bothogf them, and that a single flame may be distributed'in varying proportion to the several passages.
