INVENTOR, ,77/43? CIJZZeT;

Patented Apr. 5, 1932 PATENT OFFICE MAX CUTLER, OF LOS ANGELES, CALIFORNIA ALL-ELECTRIC AUTO COMBINATION LOCK Application filed October 8, 1929.

This invention relates to means for con trolling the starting, the ignition and the stopping or killing of internal combustlon motors such as are employed for the propulsion of various classes of vehicles, such as automobiles, water-craft and aircraft.

More directly the invention relates to an all electric system having operative devices which must be set at predetermined positions according to an index system incorporating a numbered index.

It is an object of the invention to provide an all electric control apparatus incorporating a plurality of control wheels and knobs adjusted to predetermined positions and having calibrated dials for indicating and facilitating adjustment to positions by the authorized person possessing the requisite index combination for co-relat-ive Wheels and knobs.

It is an object to provide an electric system including means for the completion and for the interruption of several electrical circuits employed in the operation and control of an internal combustion motor, such for instance as the ignition circuit and the circuit of an electric starting motor for the engine.

A further object is to provide an all electric, index and combination control means of 30 simple, practical and substantial construction and effective and reliable in operation and whereby the initiated person may quickly and easily set the control parts to the requisite position for the several functions.

An additional object is to provide a combined dial and index combination controlled and electrically operative apparatus which may be readily installed and combined with the plant or motored vehicle which is to be supplied with the novel control.

Figure 8 is a diagram of the control system as combined with indicated ignition and starter-motor circuits.

Figure 9 is a diagram showing the closed ignition circuit through its magnetic switch.

For a description of the electrical apparatus reference is made to Fig. 8 wherein is shown graphically the general electrical system as combined with a source of current as from a battery 2 from which a positive line 3 leads directly or indirectly to a binding post 4:. From this binding post leads a wire 5 to a plane faced switch bed or a plate 6 of insulative material having a contact pin 7 whose head is flush with the face of the plate 6 and to which pin the wire 5 is connected.

Bearing against and sweeping over the face of the plate 6 is a brush or arm 8 whose outer tip is arranged to swing onto the contact pin 7 as the arm is turned by its rotative shaft 9, by means later described.

From the switch arm 8 leads a wire 10 to a flush-head contact 11 in a second or intermediate contact insulative bed or plate 12 and on which turnably sweeps switch arm 13 operative by its shaft 14; the tip of the arm being engageable during its rotation with the flush-head of the contact 11.

From the intermediate switch arm 13 eX- tends a wire 15 electrically connected to a flush-head contact 16 in the ultimate or cardinal insulative bed or plate 17 which has a switch arm 18 turnable by a shaft 19 to sweep in an orbit so that the tip of the switch arm 18 can be brought to position over but not against the contact 16 until, by a pull on knob 52, it is drawn in against and completes a circuit on the contact 16.

The switch arm 18 is electrically connected by a wire 20 to the core of coil 24 which acts as a conductor in series with an armature 25 and is connected to a binding post 21 to which is electrically connected an ignition circuit 22 including the usual spark coil and spark plug elements which are shown conventionally. An object of the wire 20 is to energize coil 24 to draw over armature 25 MM. the ignition circuit through core of co l wire 23' and binding post 21.

From this it will be seen that there is provided a plurality of circuit controlling or master switches each turnable, independent of the other to engage relative contacts so that when all of the switches have been cor- 'rectly engagedwith the contacts the ignition circuit is completed through a line 27, armature 25, core of coil 24, wire 23, and binding post 21 to the ignition circuit 22.

The circuit line is connected by a branch 23 to an electro-magnet 24 whose armature 25 is normally open from the conducting core under action of a spring 26. The armature 25 is connected by the line 27 to the bus binding post 4. The electroanagnet 24 is connected by a line 28 to an armature 29 (waich is normally grounded as later described) and normally held out by its spring 30 (insulated as to armature 29) from an electro-magnet 31 which has a line 32 leading to a flush-head contact 33 fixed in the cardinal contact Plate 17 and in the orbit of the tip of the switch 18. The electro-magnet 31 has a grounded line 32' here shown as connected to a bracket 33 to which the spring 30 of the armature 29 is connected; the bracket having anadjusting and contact screw 34 engaged by the open armature 29 so that in open position the circuit of the electro-magnet- 24 is through the line 28, armature 29, screw 34 and to the grounded bracket 33. i

It will be seen that when several master switches, 8. 13 and 18 have been properly adjusted and the latter'mored, by knob 52, in momentarily to engage its contact 16 and to close the line 20, the circuit of coil 24 closed, the coil 24 is energized and its pole attracts armature 25 whereby current passes through the core of the magnet 24 to a. line 23 and thence to the ignition circuit 22. It will be seen that the ignition circuit 22 will remain closed by armature 25 so long as magnet 24 remains energized, though the switch 18 breaks contact on 16, because coil 24 is now energized by a circuit including wire 3, post 4, wire 27 closed armature 25, core of coil 94 wire 23 and shunt circuit wire 23 through 2829-30: 33 to ground. Thus, when the switches 8, 13 and 18 are closed, wire 5 feeds tl161001l 24 to close ignition circuit 22 through i start the motor, turns it to a position over,

but not engaging, a contact head 35 flush with the plate 17 and in the orbit of the out-ofcontact tip of the switch 18; the contact being connected by a wire 36 to a binding post 37 to which is electrically connected a suitable starter-switch 38 controlling a starter-motor 39 by which the engine, not shown, is turned over. Now by pulling in the switch 18 current is fed through wire 36, post 37, starter switch 38 to the starter motor 39. The switch 18 is always a positive potential as long as the armature 25 is feeding the ignition current, since it is connected to armature 25 by wire 20, line 23, to core of coil 24, to armature 25 and line 27 to battery.

For the purpose of stopping the engine the switch 18 is turned to the requisite position ready to engage the contact 33 whereby the magnet 31 is energized and draws over the armature 29 and breaks the ground circuit of coil 24 at the contact screw 34 thus deenergizing the ignition control magnet 24 and releasing the armature 25 so that the ignition circuit is thus broken between armature 25 and core of coil 24, the armature 25 being pulled open by spring 26.

For the purpose of rendering difficult the selection of the positions of the controlling switches 8, 13 and 18 at the proper places concurrently the switches are conceal .(l in a shell or box 40 and their shafts extended forwardly to and through a front panel 41 adapted to be mounted in a convenient position in front of an instrument board 42 to which the switch box 40 may be appropriately fastened as by bolts or screw 43.

In the present embodiment the switch arm 8 has its shaft 9 extended forwardly through the panel 41 and provided with a knob 44 which has a calibrated flange 45 whose calibration registers with a pointer or mark 46, Fig. 7, on the panel. Anyone knowing the index number on the flange 45 for bringing the switch 8 to correct position on contact 7 will merely turn the knob 44 to bring the dial number opposite the mark 46.

The switch 13 is secured on a tubular shaft 14 on whose outer end is secured a wheel 47 having an index flange 48 whose numbers are to be registered with a guide or mark 49 on the panel 41 to bring the arm 13 to the correct position on the contact 11 on the plate 12 which is fixed to the wall of the box 40.

The shaft 19 of the switch arm 18 passes through the tubular shaft 14 and is insulated therefrom by a tube or hearing 49. The contact plate 17, of the arm 18, is spaced. inwardly from the contact plate 12 and a spring 50 interposed between the plates serves to press the switch arm 13 firmly against its plate 12, and so hold the index wheel 47 frictionally in place.

The switch arm 18 is normally placed out of contact with its plate 17 by a spring 51. The outer end of the switch shaft 19 is provided with a knob 52 to which is secured a pointer 53 which is registerable with suitable index numbers as the dial 48.

In the operation of the device, a person knowing the correct index combination numbers, simply turns the knob 44 to registerthe effective index number of flange 45 with the mark 46 at which setting the switch 8 will be moved onto the contact 7. The index wheel 47 is then turned to register the proper index number with the mark 49 to bring the switch arm 13 into register with contact 11. For energizing coil 24 to draw over armature 25 and thereby closing the. ignition circuit the knob 52 is turned to bring the switch arm 18 over its contact 16. hen the several switches have been properly registered according to the code of numbers then the knob 52 ispulled outwardly so as to draw the switch 18 against the contact 16 by overcoming spring 51 and as soon as the electrical contact is made the ignition is closed by engagement of armature 25 on core of coil 24 even though the knob 52 is released. Since the armature 25 has been attracted to the magnet 24 (whose circuit is shunted through 23-+2833) and closes ignition circuit through the line 23 the next step is to turn the knob 52 to bring the switch arm 18 over the contact 35 and then pull the knob 52 forward to bring the switch against the contact 35 and thus close the starter switch device 38.

To finally stop or kill the engine, the knob 52 is turned to register with the contact 33, Fig. 8, and is then pulled to engage the arm 18 with the contact 33, whereupon the electrical magnet 31 is energized and its armature 29 breaks the ground circuit of switch coil 24 at contact screw 34 thus de-energizing magnet 24 and releasing its armature 25 and breaking the ignition circuit through line 23 Since the several contacts 7, 11, 16, 35 and 33 are all flush with the surfaces of the insulative plates 6, 12, 17 the tips of the brushes on switch arms will glide over the surfaces without feel efiiect through the knobs so that a' person not knowing the combination numbers cannot position the switches by the sense of touch.

The electro-mechanical, secret-index combination device is shown as combined with a manual brake lock, Fig. 1', including an electro-magnet having a line 61 to the ignition post 21 and being grounded at 62. This magnet attracts an armature 63 pivoted at 64 and having ahook latch 65 pulled down by a spring 66 into the path of action of a locking lug 67 fixed a'djustably on the end of a brake rod 68 operative by a lever 69.

When the brake is set by the rod the lug 67 passes under the latch 65 and cannot be released to free the brakes until the magnet 60 is energized to pull over the armature 63 and thus lift the latch. Preferably the magnet 60 is energized concurrently with the ignition circuit and holds'the lock open until the ignition is killed. The brake can be set or released at will while the ignition is on.

The dial panel is provided with a start symbol ST and a kill symbol K. As soon as the driver has set all the combination dials and knobs to effect starting of the engine and has started the engine then the driver may immediately jumble the index devices to prevent the combination beinglearned by any one else. If the engine is stalled for any reason the driver may turn the control knob 52 to the symbol ST and immediately start the engine without resetting the combination devices; the symbol being so positioned that the switch will be brought to the right position on the starting circuit contact. The kill symbol K is so positioned that the control switch can instantly be turned to the ignition circuit breaking contact as will be desired when vehicle is driven to the curb without setting of the control combination elements.

It will be seen that when the ignition circuit is broken through use of the symbol K position that it will be necessary to again set the proper combination of dials and knobs before the ignition circuit can be closed and the engine started.

Fig. 9 shows how the armature arm 25 is held closed against tension of its spring 26 by its energized magnet-core 24 whose coil is ex cited by current from 2, 3, 4, 27 23, 23, to- 28 to ground 2933.

The master switch 18 is yieldable against its spring 51 which keeps it out of contact with 16 at all times unless pulled to contact by knob 52. The ignition current runs on the closed magnetic switch 25.
