ELECTRICAL APPARATUS.

Specification of Letters Patent.

Patented Feb. 10, 1920.

To all whom it may concern:

Be it known that I, JOSEPH BIJUR, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented a new and Improved Electrical Apparatus, of which the following specification is a full disclosure.

This invention relates with regard to its more specific features, toelectrical apparatus for the lighting and starting of automobiles and the like.

One of the objects thereof is to provide simple and practical apparatus of the above nature in which the current is economically used. Another object is to provide a convenient and reliable arrangement whereby the unauthorized use of a car may be prevented. Another object is to provide means in connection with apparatus of this nature whereby injury to the parts is prevented under all conditions of use.

Other objects will be in part obvious from the annexed drawings and in part indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combinations of parts, and in the unique relations of the members and in the relative proportioning and disposition thereof; all as more completely outlined herein.

The accompanying drawing, in which is shown one of various possible embodiments of this invention, is a diagrammatic plan.

In this drawing there is indicated at 1 an internal combustion engine connected as by the sprocket chain 2, or other power transmitting device, with dynamo electric apparatus 3. The latter apparatus preferably takes the form of a dynamo electric machine adapted either to turn over the engine to start it or to be driven therefrom as a generator and supply current to the battery, hereinafter referred to.

Leading from one of the brushes of the dynamo 3 is a conductor 4 which has connected therein an electro-magnetic charge indicator 5. This indicator or meter is of a well-known type and in the preferred form merely registers whether the storage battery is being charged, discharged or floating, in accordance with the position of the needle relative to the indices 5, 5" or 5, This device, the precise construction of which forms no part of this invention, may be termed a meter, it being understood that this term is used in a broad sense to comprehend any electro-magnetic indicating or registering device. The conductor 4 terminates in a contact block 6 and a conductor 7 leadin from the above terminal of the dynamo 1s connected with a contact block 8, these contacts being preferably arranged along the arc of a circle and separated by an insulating block 9.

Leading from the remaining terminal of the dynamo is a conductor 10 which is connected with one pole of a storage battery 11, the remaining pole of which is connected by a conductor 12 with a movable contact 13 formed upon the arm 14 of a rotary switch pivoted at 15 and actuated as by the thumb-piece 16. The contact 13, in its range of movement, passes from a dead contact 17 over an insulation block 18 and thence successively to the parts 8, 9 and 6. It is to be particularly noted that this movable contact is of such length that in traveling in the above direction it bridges the contacts 8 and 6, as indicated in dotted lines at 19, and thus maintains connection with the conductor 7 until it has made connection with the conductor 4.

The arm 14 is carried past the pivot 15 and bears at its opposite end a movable contact 20 which traverses an arc comprising contacts 21 and 22, spaced by the insulating member 23, and also a member 24 which serves to support the contact-2O at its upper range of movement. It may be noted that this range of movement is limited, as by suitable stops 25 and 26, and that there is provided to turn with the switch arm an angular plate 27 having fiat surfaces which successively rest against the flattened portion 28 of spring 29 in the positions in which the contact 13 rests upon contact 17, contact 8 and contact 6. In this manner, the switch member tends to occupy one of the above three positions of rest, and if desired a lock device 29 may be provided to secure it in the off position shown in full lines in the drawing.

There is shown at 30 an ordinary magneto, the primary circuit of which is completed through the usual interrupter 31 and the secondary circuit of which leads through a distributer 32 and the spark plugs 33. This magneto, which may indlcate any .A connection to ground from the primary circuit of this magneto leads through contact 21, as indicated at 3%, and through a conductor 35 to the contact 22, these contacts being connected by the member 20.

With the parts in the normal off position shown, in which they may be locked if desired, the contact 20 bridges contacts 22 and 21, thusshort-circuiting the interrupter and rendering the magneto inoperative. In this manner it is assured that the engine cannot run with the switch in the position shown, even 1t it be cranked by hand, and

the car is safe-guarded against unauthorized use.- Also, if the switch be opened after theengine is started and circuit thus broken with the battery 11, the system is guarded from an undue rise of voltage by the automatic stopping of the engine.

In the use of this apparatus, when it is desired to start the engine the switch is turned to bring contact 13 into engagement with contact 8. This action breaks the shunt about the interrupter 31 and permits current to flow from the battery 11 through the dynamo 3, undiminished by being forced to traverse the meter 5. In this manner the meter is not subjected to the necessarily large current employed in running the dynamo 3 as a motor to start the engine, and, furthermore, this current is not cut down and wasted. After the engine is started, the

switch is turned further until contact 13 comes into engagement with contact 6, interruption of the circuit being prevented as already described. The apparatus now runs in the ordinary way, with the dynamo 3 charg ng the battery 11, the meter being in use. When it is desired to stop the engine, the switch is merely returned to its normal off position, as shown in the drawing.

It will thus be seen that there is provided apparatus in which the several objects of this invention are achieved.

As many changes might be made in the above 'onstruct on, and as many apparently d ii'erent embodiments might be made of this invent on without departing from the scope thereof. it is intended that all features herein des"ribed or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having thus revealed this invention, I claim as new and desire to secure the following combinations of elements, or eouivalents "engine to start it, means connecting said dynamo with said engine, a storage battery, 'an indicator, a conductor leading to said dynamo independently of said indicator, a conductor leading tosaid dynamo through said indicator, and means adapted to connect said battery successively with said conductors in the above order tostart said engine and to charge said battery, said last means being formed to maintain connection with said first conductor'until it has made connection with said second conductor.

2. In apparatus of the class described, in

combination, an internal combustion engine, a storage battery, dynamo electric apparatus connected With said engine, means adapted to connect said battery to said apparatus through one conductor to cause it to turn over and start said engine and through another conductor to receive current from said apparatus after said engine is started, said means being formed to maintain connection with said first conductor until it has made connection with said second conductor, said second conductor being serially connected between said battery and said dynamo electric apparatus, a magneto connected to serve as a source of current for ignition of the charges of said engine, and means adapted to maintain said magneto operative upon said battery being connected to said apparatus and to render it inoperative upon said connection-being broken.
