`with a plate 61 connected with a plate 59.;
`brush 51 into contact with.a plate 60 con-
`nected with plate 58 and brushes 52 suc-
`cessively into contact with plate 59. This
`reverses the direction of the dynamo and
`causes it to drive the engine and car back-
`ward. The above operations are well un—
`derstood by those skilled in the art and are
`all
`in accordance with ordinary and well
`known practice.
`‘
`the power ab-
`Manual regulation—As
`sorbed by the car depends upon the speed as
`well as upon the nature of the surface over
`which it travels it is liable to wide variations,
`but as long as the amount of ower required
`falls short of that developed y the engine,
`the eXcess is utilized in chargingthe second—
`ary battery. As soon, however, as an in-
`crease in propulsion power is required, as Will
`. happen, for example, whenever the car en-
`counters an up-grade, the slackening of the
`speed causes the dynamo to work as a motor,
`thus supplyin
`the engine with the addi-
`tional power w ich it requires to kee up an
`approximately uniform speed.
`It t us fol:
`lows that the speed of the engine is at all
`times dependent, upon the predetermined
`electrical running conditions of the dynamo.
`In the case of internal combustion engines
`of the class herein contemplated it has-hereto—'
`fore been. customary, as one means of render-
`ing available their. maximum poWer, to vary
`.the time of-spark relatively to the speed of
`rotation, and tense for this purpose what is
`known as a sparking cam, the position of.
`which is altered to give what is termed “the
`advance.” Other means may be employed
`for this purpose, but in "the present case I
`have shown means‘for securin a constant
`ratio between the “sparking a vance” and
`the speed of the engine which consists in a“
`connection between‘lever 20 and
`the sparking,

`cam 24, effected by
`means of a rod 25 shown“
`in detail in Fig. 4. By the operation of the
`lever 20 for working the controller 6 a corre-
`sponding change in the position of the cam
`24 will be brought, about for each position
`of the lever, so that the best possible time
`for sparking according 'to the speed will thus
`be assured. Moreover, as the feed of hydro
`carbon liquid into the mixing chamber of a
`carbureter
`is pro ortio‘nal, among other
`things, to the speed of« the engine, it is nec-
`essary, in order to maintain inthe ex losive
`mixture a constant ratio of hydrocar on to
`air, to vary the proportion of air in propor-
`tibn to the increase of s eed.
`. To accom-
`plish this, and to supply the requisite quan-
`tity of air correspon ing

`sition of the lever 20 and admit a properly

`the movement of the said lever 20 serves to
`control simultaneously the, speed, sparking

`the explosive
`charges in re ortion to the work which the
`engine is ca 16 upon toiperform at any given

`'bustion engine, is arranged a throttle valve,
`or obturatcr, 28 ‘of
`the butterfly form
`worked by a Solenoid 29, provided with a
`double Winding. One of these windings is a
`'fine wire 44 in shunt Or derivation to the
`battery terminals, while the other is of coarse
`wire 45 ineludedm in the main circuit of the
`dynamo and battery 5.} The parts above
`described are/designed and adjusted for the
`following operations. The fine wire shunt
`Winding permanently energizes the solenoid
`tending to draw into it the soft iron core 30
`against
`the action of a counter—balancing
`spring 31, but as long as the battery is not
`entirely charged the effective pull of the
`solenoid, due to the magnetizing effect cf the
`shunt winding,.is not sufficient to more than
`partially close the valve 28. The shunt
`winding 44 is, however, assisted by the mag»
`netizing effect of the series coil 45, the di—
`rection of winding of which is such as to add
`its effect
`to that of the shunt while the
`battery is being charged. The combined
`action ,of the two windings, as shown in Fig.-
`8, thus efl’ects a more or less complete closure
`of the valve 28, and a corresponding reduca
`tion of the power of the engine, widen there-

`
`trength compatible with the condition of the
`battery lates. On theother hand,
`if by
`reason 0 an increase in the load, such as
`would ’be due to the car encounterin~ an
`up-grade, the speed of the internal combus—
`tion engine is reduced, the counter electro—
`motive force of the battery will overcome
`the electromotive force of the dynamo, and
`the battery will therefore discharge through
`the latter. The flow of current in-the main
`Winding being then in opposition to'that in
`the shunt,
`the' magnetlzmg effects of
`the
`two partially cancel out, and the force of the
`spring 31 preponderating, will raise the’core
`30 and open the valve 28, as shown in Fig. 6,
`this giving the engine greater power.
`By the use of the system or combination
`' hereinbefore described, the following, among
`other advantages are secured. First, ' the
`gas supply to the engine is controlled and so
`. mamtamed as
`to assure to the battery,
`without unnecessary consumption of fuel,
`the desired uniform condition of charging.
`Second ;
`the charging current is prevented
`from -exceeding the predetermmed and
`propers'trength.i Third; wheneverthepower
`demanded of
`the internal combustion en-
`gine necessitates drawing on the electrical.
`, [the volume of
`energy stored in the battery
`the explosive charges admitted to the en ine
`is increased to a degree that enables the at—
`ter to supply its maximum power. Fourth;
`the most efficient working conditions are
`automatically maintained, so that economy
`in operation' is dependent
`to a much less
`degree on the skill and proficiency of the
`driver.

`
`In the ear herein illustrated, the engine and
`dynamo—motor occupy considerable space
`lengthwise of the frame, so that I have de-
`vised a suspension arrangement by'which the
`bending of the frame of the car will not effect
`the operation of the combined motor and en-
`gine. For this purpose, the motor set is sus—
`pended from three different points on the
`frame, to two of which the dynamo is con-
`nected, and to the, third the engine. This
`sus ension is secured by means of lugs in piv—
`ota bearings and fastening nuts, as shown in
`Figs. 1 and 2, the three points of suspension
`being indicated at 32, 33 and 34.
`Although the magnetic brake is shownand
`described in detail herein in order to exhibit
`
`a complete and operative system, it is not
`claimed in the, present application.
`Having navigdescribed my invention what
`I claim is:
`‘
`1. The comblnaiion with a mixed power
`set-“comprismg anengine of the kind de—
`scribed, a dynamo motor connected there—_
`with and an accumulator in circuit with the
`dynamo motor, of a manually operated con—
`troller for the set, and independent means
`for controlling the power of the engine, auto-
`matically dependent for operation upon the

`7. A propulsion plant comprising in com—
`bination an internal combustion engine, a
`dynamo motor‘ driven thereby,.a secondary
`battery in circuit with the dynamo motor, an
`electrical controller, an' engine ignition de-
`vice, a connection between the same, and the
`lever of the controller, an engine throttle
`valve and a solenoid for controlling the same
`havin two energizing windings, one in shunt
`to an the other in series'with the secondary
`‘battery, as and for the purpose set forth.

`the following elements to wit :—-—an internal
`combustion engine, a dynamo motor driven
`thereby, an accumulator in circuit with the
`dynamo motor, an electrical controller for
`said dynamo motor,‘an engine ignition de-
`vice and an air supplyregulator, both opera-
`tively connected With said circuit—controller,

`axle in said bearings, a driven axle in said
`bearings,,wheels on said axle, an‘ internal
`Combustion engine, a dynamo motor, a shaft
`connecting said engine and dynamo motor,
`an electro—magnet .on said shaft, a power
`transmission shaft, a magnetic element on
`said‘transmission shaft disposed near said
`electrO-magnet, a'n electro—magnet on the
`frame‘ disposed near said electro—magnetic
`element, means connecting said transmission
`shaft with the driven axle, an electrical ac—
`cumulator, an engine control, electrical means
`operating-said control, an ignition device, an
`air supply, means for controlling the same,
`an electrical controller for the dynamo motor
`and a connection between said controller and
`the means for controlling the ignition device
`and the engine air supply as set forth.
