- SUMMARY OF THE INVENTION A card formed of insulating material provided with a plurality of ball contact members which extend out each face of the card for electrical contact with the electrical contacts of a lock. The electrical contacts of the lock are connected in such a manner and related to the contact of the card that when proper mating of the card with lock occurs the motor vehicle is permitted to operate, but when improper mating of a card and lock occurs a warning signal is sounded.
The primary object of the invention is to provide a lock system actuated by a contact carrying card such as to give a warning signalwhen the wrong card is inserted into the lock.
Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings.

FIG. 2 is an exploded sectional view, taken along the line 2-2 of FIG. I, looking in the direction of the arrows;
FIG. 3 is a horizontal sectional view, taken on the line 3-3 of FIG. 2, looking in the direction of the arrows;

FIG. 5 is a vastly enlarged fragmentary sectional view, taken on the line 5-5 of FIG. 4, looking in the direction of the arrows.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference numeral indicates generally a combination card key and lock system constructed in accordance with the invention.
The system 10 includes a lock 11 formed of insulating material and having a generally rectangular shape. The lock 11 has a flange 12 formed on one end thereof for securing the lock II to a steering column 13 of a motor vehicle.
A relatively thin generally rectangular pocket 14 opens into the lock II and extends nearly all the way therethrough. A plurality of contact buttons 15 embedded in the insulating material forming the lock 11 so that their inner ends coincide with the surface of the pocket 14. The plugs 15 are provided with insulators 16 on their outer face and electric circuit wires 17 extend therefrom in a manner to be described.
A combination key card 18 is formed of plastic or any non-conducting material and has a plurality of conducting or non-conducting balls 19 secured between the opposite sides of the card 18 in such a manner as to cooperate with the plugs 15 on opposite sides of the pocket 14 to complete a circuit there-between.
For convenience of description the contact balls 19 are lettered A, B, C, D, E and F and similarly the contact plugs 15 in the lock 11 are lettered A, B, C, D, E and F both in FIG. 1. The card 18 may have anyone of the balls 19 either omitted or formed of nonconducting material so as not to complete a circuit between adjacent plugs 15 with the card 18 inserted into the lock 11.
The wires 17 may interconnect any of the plugs 15 lettered A, B, C, D, E and F to provide the desired circuit. In the lock 11 as illustrated in FIG. I the contacts A and D, contacts C and F and contacts F and E on the upper side of the lock are interconnected and the contacts B and C, A and D and D and F are interconnected on the lower side of the lock. To establish the desired circuits the balls B, C, and E in the card 18 are formed of conducting material while the balls A, D, and F are formed of non-conducting materials or omitted. Inclusion of conducting balls A, D, and F will cause the alarm to be sounded even if balls B, C, and E are properly included.
A wire 21 connects the contact B on the upper side of the lock 11 to the plus side of a battery 22. A wire 23 connects the plus side of the battery 22 to the contact D on the upper side of the lock 11. A wire 24 connects the contact D on the lower side of the lock 11 to a relay 25. The relay 25 actuates a switch 26 and a switch 27 for reasons to be assigned. A wire 28 extends from the relay 25 to the negative side of the battery 22. A wire 29 extends from the contact E on the lower side of the lock 11 to a hand control switch 30. A wire 33 connects the switch 30 to the switch 27 connected by a wire 34 to the load 35. A wire 36 extends from the load 35 to the negative side of the battery 22 through the wire 28.
A wire 38 extends from the positive side of the battery 22 to a horn 39 which is connected on its opposite side by a wire 40 to the switch 26 and from there by means of a wire 41 to the negative side of the battery 22 through the wire 28. A pair of jumper contacts 42 are connected across the switch 30 so as to permit the connection of jumper cables from a hot battery with the switch 30 open when the battery 22 is discharged and when auxiliary electrical power is needed.
In the use and operation of the invention the card 18 is inserted into the pocket 14 with the contact balls 19 making contact between the plugs 15 on the opposite sides of the lock 11. With the card 18 inserted a circuit is established from the wire 21 to the top contact 158 through the ball 19B, bottom contact 158, bottom contact 15C, ball 19C, top contact 15C, top contact 15E, ball 19E, bottom contact 15E; closing the hand switch 30 provides a circuit through the switch 27 to the load 35 to permit the vehicle to be operated. If any of the balls A, D, and F are formed of conducting material a circuit is established through the wire 24 to the relay 25 which closes the switch 26 to the horn 39 and opens the switch 27 to deprive the load 35 of electric- The card 18 may have any one of the balls A, B, C, D, E and F formed of conducting material, nonconducting material or omitted and the lock 11 is provided with suitable circuits to sound the alarm of the incorrect card is inserted therein and to provide electricity to the load when a card having only the correct combination of conducting balls is used therein.
Having thus described the preferred embodiment of the invention it should be understood that numerous structural modifications and adaptations may be resorted to withoutdeparting from the spirit of the invention.
What is claimed is:
1. in an electric combination card lock for a system, an electrically actuated alarm and an electrically energized engine, a lock formed of insulating material and having a generally rectangular shape, said lock embodying a relatively thin card receiving pocket extending substantially all the way therethrough, a plurality of spaced contact elements embedded in the lock on opposite sides of said pocket and said contact elements coinciding with the surfaces of the pocket, insulators on the outer surfaces of said contact elements, electric 4 circuits separately connecting at least one of said contact elements to an electrically actuated alarm circuit and at least one other of said contact elements to an electrically energized engine circuit, a relatively thin flat key card formed of insulating material insertable in the pocket of said lock, a plurality of selectively conductive and nonconductive balls rigidly mounted in said key card between opposite sides of the card with each ball extending from opposite faces of said card, said card with said conductive balls being adapted to electrically interconnect at least some of the contacts in the pocket of said lock to complete a circuit to said alarm, to said engine, or to both said alarm and said ongine, and a hand control switch battery electrically connected in said circuits.
