26 Claims.

This invention relates to an internal combustion engine including means for starting the engine and. aiding the functioning of the lubricating system thereof under conditions which would.

larly under such adverse starting conditions as those which obtain at low temperatures, by utilizing the heat generated by the combustion in an auxiliary internal combustion engine to preheat the cooling medium in the main engine and in any other parts desired, such as the carburetor fuel pump, etc.

Another important object of my invention is to provide means to preheat and circulate the lubricating oil under greater than normal pressure to the various bearings, thereby assuring thorough lubri.cation,`prior to, during, and after starting the main engine, as Well as promoting easy starting.

Another important object of `this invention is to provide simple and efficient means for charging the storage battery of the main internal combustion engine at any time or place Without resorting to any outside source of supply of electrical energy.

Another important object of the invention is to provide means for supplying additional energy other than that from the storage battery for starting purposes, by operating the auxiliary internal combustion engine to drive the electric generator of the main engine as a motor-generator set to assist the said storage battery in supplying electric energy .to the electric starter motor and ignition coils during the starting period.

Another important object of the invention is to provide means for supplying a higher voltage, for ignition purposes, than is obtainable from the storage battery during the starting period, by inserting resistance means in the circuit between the generator and the junction of the battery and starter motor circuit, and by connecting the primary of -the main engine ignition coil between the aforesaid resistor and electric generator.

Another important object of the invention is to provide meansfor driving the oil pump, by means of the electric starter, to supply oilv to the main engine bearings, etc., prior to starting the main engine,4 ,When it is not desired tooperate the auxiliaryengine to circulatezthe oil prior to starting the main engine, the oil pump may be operated, without the functioning of the auxiliary engine, merely by operating the electric starter in the reverse direction `iust long enough to establish oil pressure, prior to operating the electric starter in the normal or forward direction to start the main engine. This feature is very desirable in Warm weather and particularly when the main engine has been standing overnight after having been operated at fairly high temperature, in which case the bearings are quite dry, because the oil which was thinned at high temperature lo has drained from the bearings. While, under such conditions, the starting conditions are not severe enough to require operation of the auxiliary engine, it will greatly prolong the life of the bearings if the oil pressure in the bearings is established by merely spinning the oil pump, by

operating the electric starter in the reverse direction, for a moment, prior to starting the engine.

A still further important object of my invention is to provide means to preheat the storage battery,

by operating the electric generator by means of the auxiliary engine, prior to starting the main engine. Aside from the chemical energy which will be stored in the battery, during operation of the generator, some of the generated electrical energy, in overcoming the electrical resistance of the battery, will be transformed into heat energy which will raise the temperature of the battery. While it is not generally known, it is a proven fact that with a given resistance load, as for example, the starter windings, the output of a battery, during cold Weather, will be greatly increased if preheated. Hence, it follows that the preheated battery Will supply the electric starter and ignition coils with an appreciably greater amount of electrical energy.

In addition to facilitating starting of the main engine the auxiliary engine may be used to circulate the medium used in car heaters for heating the interior of the vehicle particularly when the main engine is not in operation. While such a car heater for the interior of the vehicle is not shown, it may be of any type and may be connected to any desired point in the system Whether it beof the cooling-Water or hot-air type.

Further, the auxiliary engine may be operated to drive the water pump, oil pump, and generator at a higher speed than that corresponding to the main engine speed to increase the circulation of the cooling medium, the pressure of the oil and hence the `supply to the bearings, and the amount of current to provide sufiicient circulation of cooling medium, oil Supply, and electric current.

The accompanying gures together With the description of the construction and operation of the apparatus embodying my invention are to be understood to be illustrative only and for the purpose of making clear the nature` and manner of employing the invention, and that the invention is` not to be regarded as limited to the precise mechanism illustrated nor to any detail thereof. Voltage'and current regulators of any kind may be employed depending upon the electrical apparatus used and the operating characteristics desired.

The exhaust gas may be utilized to heat any part of the main engine and any method, other than employing an exhaust gas chamber surrounding the auxiliary engine water jacket, may be used to transfer the h eat of the exhaust gas to the cooling medium of the main engine.

Referring in' detail to the drawings, the numeral I refers generally to a conventional starter motor wound so as to be capable of being operated -in reverse. and forward directions. In the forward or normal direction the starter drive engages the flywheel of themain engine tostart the same, and in the reverse direction the starter motor acts to start the auxiliary engine through the cooperation of the over-runningmclutch 2 connected to the auxiliary ,engine shaft 2a. This overrunning clutch engages only when the starter motor is operated in the reverse direction. The

` numeral 3 refers to the crank case of the auxil- Alary engine, and the numeral 4 refers to another oppositely placed over-running clutch which connects the opposite end of the auxiliary engine shaft 2a to the water pump shaft 4a, the water pump being designated by the numeral 5. The

members which will permit similar action, where-1y by the generator, cooling medium pump, or oil pump, ormore than one of these elements, can vbe driven faster than at corresponding main engine speed or while themain engine is not running.

The numeral 6 refers generally to the intake pipe of the cooling medium pump which is jacketed by a casing I0 to form an annular chamber heated by the cooling medium` or cooled by the cooling medium in the pipe 6 for heating or cooling the oil which is l'ed thereinto by the pipe I2 from the main engine crank case I2a, and dischargedby means of the pipe 9 which is connected to the intake of the oil pump 1. The oil pump outlet pipe 8 carries the oil to lubricate the main engine and auxiliary engine if desired. The oil pump shaft 1a is directly coupled to the shaft of the generator I3. It will`be observed that in the oil cooling or heating chamber II which is dened by the jacket Ill and the pipe 6, the oil may be cooled when too hot, and warmed when the engine is cold to facilitate starting.

vThe numeral I4 refers to an over-running pulley which is mounted on the generator shaft and connected to the fan assembly I6a by the belt I4a trained over the pulley I4 and the fan assembly pulley I5a, whereby the generator, the oil pump, and the cooling medium pump, are

` normally driven by the main engine as it is operating under normal circumstances. Of course, where the generator drive is through gears or through a belt other than that which drives' the fan, a suitable overrunning arrangement of the connection to the generator may be provided for, without invention. The overrunning pulley I4 engages the shaft vof the generator only when the generator is being driven by the main engine.

'Ihe numeral I6 designates a by-pass pipe between the radiator outlet I1a and the radiator inlet pipe I8a, the outlet pipe I1a being directly connected to the cooling medium pump intake 6, andl the radiator inlet pipe I8a. being directly connected to the by-pass thexmostatically operated valve I9 at the top of the radiator I1. The numeral IllIl designates generally the cooling medium jacket and head of the main engine.

Referring in particular to Figure 2, the numeral 2| generally designates the combustion chamber of the auxiliary engine, the numeral 22 the cylinder Wall, the numeral 23 the cooling mediun chamber which connects with the cooling medium pump through the pipe 34, and the numeral 24 designates the outer wall of the cool- ?ing chamber which serves as the inner wall of the exhaust gas heating chamber. The exhaust gas heating chamber is generally designated 25 and has the outer wall 26. The passage 21 connects the exhaust port 28 to the exhaust 'gas chamber 25.

The numeral 29 designates a valve which is arcuate in form and rotatable and is capable of being positioned to permit the exhaust gas from the exhaust port 28 to flow directly to the exhaust pipe 30 or` instead through the passage 21 to the exhaust gas chamber 25 and thence to the exhaust pipe 3l. The exhaust pipe 30 connects directly with the exhaust port 28 when the valve 29 is in sucha position that it closes the passage clutch 4 engages only when the auxiliary engine'i 21. The exhaust pipe A3l connects both the exis running faster than the shaft 9S 11h? WMS! haust pipe 30 and the exhaust gas chamber 25 to the mainengine exhaust manifold or to any other desired point.

The numeral 32 generally designates the spark plug of the auxiliary engine.

The pipe 33 connects the auxiliary engine cooling chamber with the cooling chamber or cooling medium water jacket of the main engine, directly or indirectly, depending upon whether or not the cooling medium is to be employed for warming or cooling elements additional to those shown, such as fuel pumps, carburetor, or a heater for the interior of the automobile, and the like. The pipe 34 connects the cooling medium pump 5 to the auxiliary engine cooling chamber 23. While an auxiliary engine of the two-stroke-cycle type is shown, I desire to include within the scope of the invention an auxiliary internal combustion engine of any type and construction.

Referring to Figures 9 through 11, thestorage battery is designated 35, the numeral 36 designates the armature winding of the starter motor, and the numeral 31 the series wound eld of the starter motor. The numeral 38 designates the ignition coil of the auxiliary engine, the numeral 39 the contact breaker of the auxiliary engine primary ignition circuit, the numeral 40 the contact points ofthe auxiliary engine primary circuit, the numerali4| the contact points of the ignition switch of the auxiliary engine, and the numeral 42 the movable element of the auxiliary engine ignition switch.

The numeral 43 designates a contact mounted on but insulated from the auxiliary engine ignition switch, the numeral 44 a contact connected to the electrical conductor 49, they numeral 45 a contatrconnected to the conductor 51, and the numeral 46 a resistor connecting the starting switch contacts 41 and 48. The numeral 41 designates the contact on the stationary contact on the starter switch, the numeral 48 another stationary contact on the starter switch, and the numeral 49 the conductor which short circuits the resistor 46 when the auxiliary engine ignition switch 42 is open, thereby causing contact 43 to short circuit contacts 44 and 45.

The numeral 50 generally designates the movable contactmember of the starter switch, the numeral 5| the insulator between the contact 50 and thev contacts 54 and 55. 'Ihe numeral 52 designates a stationary contact to which one end of the field winding of the starter motor is ',connected, and the numeral 53 another stationary contact similar to the stationary contact 52, the former being connected to the opposite end of the field winding of the starter motor. The numeral 54 designates a contact which short connects the contacts 53 .and 56 when the starter switch is in the position shown in Figure 10, for starting the main engine.-

Thenumeral 55 designates a contact which is adapted to connect the contacts 52 and 56 when the starter switch is in the position shown in Figure 9 for starting the auxiliary engine. The numeral 56 designates a contact which is connected to one of the brushes of the starter motor, the remaining brush, which is of opposite polarity being grounded as shown. The numeral 51 is a conductor connecting the breaker point of the element 6| with the contact 41.

The numeral 58 generally designates the main engine ignition switch, the numeral 59-the'main engine ignition coil, and the numeral 60 the rnain engine distributor.

The numeral 6| generally designates the generator cut-out of the main engine, the numeral resistor 46.

ignition coil during the starting, if the auxiliary engine ignition switch 42 is in the positionshown in Figure 9. It will be readily seen that with the auxiliary engine ignition switch open as shown in Figure 9 the insulated contact 43 short circuits the contacts 44 and 45, thereby short circuiting the 'I'his permits the battery terminal voltage to be impressed across the primary 4f the main engine ignition coil during the starting. However, if the auxiliary engine is operating whil\ the main engine is being started it will be seen` that the switch 42 is in such a position that contacts 4| are closed and the contacts 44 and 45 arei open, thereby inserting the resistor 46 in the electrical circuit. 'I'his resistor, while permitting the generator to supply some current to the starter motor thereby assisting the storage battery, will permit a higher voltage to be available for the primary of the main engine ignition coil than would be available ordinarily from the battery. This facilitates starting, particularly in cold weather. The resistor 46, however, may be omitted where the generator or the regulator or both are properly designed to warrant its. omission.

It will be obvious from the foregoing that the auxiliary engine may be operated while the main engine is running, to pump a greater amount of cooling medium through the cooling system, a-

greater amount of oil or of oil under greater pressure, and that this arrangement may also be utilized for causing the generator I3 to turn at a higher rate than it is ordinarily turned by the fan belt or gear connection with the main engine, for charging the battery of the automobile at a greater rate than would ordinarily be the case at the speed at which the main engine is running. When the main engine is cold and it is desired to start the same, the cooling medium will be heated by the auxiliary engine being put into operation before d starting the main engine, and this cooling medium which is being heated by the auxiliary engine will be circulated by the cooling medium pump 5 through the cooling system of the main engine and any other parts to be heated by said cooling medium, and at the same time the oil may be pumped from the crankcase of the main engine through the oil heating chamber and under a greater than normal pressure to insure its circulation in the main engine before, during and after starting of said main` engine, and similarly the generator may be operated to assist the battery to supply a greater than ordinary amount of current to the starter motor, thereby assisting the turning over of a stiif engine, and to furnish a greater than ordinary amount of current for ignition purposes for the starting of the main engine. As soon as the main engine starts, which is effected by the usual adjustments of the throttle spark and choke, by operating the starter motor in the normal direction, the starter switch is released, thus allowing the starter motor drive to disconnect from the main engine. Once the main engine has started and has begun to run at a greater relative speed than the auxiliary engine, the over-running pulleyV I4 will connect the elements with which it is operatively associated and this condition willremain until the auxiliary engine be operated at such a speed as to be turning over relatively faster than the main engine, in which case the over-running pulley I4 will overrun and the over-running clutch 4 will come into action to pump the cooling medium and the' oil at the desired rate, as well as drive the generator at an increased rate. By reason of these arrangements, driving the automobile on which the main engine is mounted at low speed may be facilitated by a relatively greater circulation of the cooling medium and of the lubricating medium, and this maybe supplemented by a relatively greater current supply to meet the greater demands of low speed driving.

may be operated toY automatically close the pipe 30 while the cooling medium is cold and close the passage 21 to the exhaust gas heating chamber 25 when the cooling medium is hot. The valve 29 may be operated automatically by connecting it operatively by means of the rod 29', to the arm 20 of the thermostatic valve 20, or to a pressure valve, (not shown) connected at some point in the pipe I6, the said pressure valve being actuated by the pressure within the pipe I6.
