Claims.

My invention relates to a new and useful push button automobile engine ignition and starter system and has for one of its objects to provide a Combination of electrical elements to be semiautomatically actuated in a preselected sequence to complete a prearranged ignition circuit and a complementary starter circuit.

Another object of the present invention is to produce a push button automobile engine ignition and starter system comprised of a dial having ten push button circuit closers numbered one to nine and zero, in combination with an electromagnetic selector unit capable of completing an ignition and a complementary starter motor upon pressing a preselected combination of three of the push button circuit closers.

Another object of this invention is to provide, in a device of the character mentioned, ten differently indexed button circuit closers capable of producing a selective total of seven hundred twenty different three-button combinations. Preferably the buttons are numbered from one to nine and zero, inclusive, and the different three-button combinations are produced without using any double or triple combinations such as 331, 455, 545 or 666, etc.

Another object of the invention is to provide an arrangement of circuits and also a particular arrangement of button circuit closers whereby certain preselected buttons must be actuated in a predetermined sequence to close an ignition circuit and a complementary starter motor circuit, and the operation of other button circuit closers will not close said circuits or will completely open or neutralize said circuits if either is partially or wholly closed, thereby nullifying any highly improbable progress an unauthorized person may have made towards solving the combination by experimentation.

Another object of the invention is to provide a control or master switch in the main circuit whereby authorized persons, such as garage attendants, to operate the automobile without knowledge of the combination necessary to close the ignition circuit and partially complete the starter motor circuit.

A further Object of this invention is to provide means for readily, quickly and easily changing the preselected combination of circuit closing buttons required for closing the circuits whereby use of the automobile by an unauthorized person ma be frustrated even though such person may have surreptitiously learned of the former combination.

A still further object of this invention is to produce a coaxial armored conductor to hinder tampering with the installation or to short one of the circuits, due to attempted tampering, whereby operation of the automobile will be prevented.

With the above and other objects in view this invention consists of the details of construction and combination of elements hereinafter set forth and then designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same I will describe the construction thereof in detail referring by numerals to the accompanying drawings forming a part hereof, in which: i

Fig. 8 is a top plan view thereof.

Fig. 9 is an end view of the same.

Fig. 10 is a rear view of Fig. '7 showing the connection with the partly broken away arm or lever of a twin armature.

In carrying out my invention as herein embodied l5 represents the push button dial, including a panel I6 of insulating material having a plurality of stationary contacts I! mounted thereon, preferably ten in number and equally spaced apart in a circle. For purposes of illustration said stationary contacts I! each comprises a large headed screw having the shank projected through the panel IS with the head resting on the obverse face of said panel and a nut 58 screwed on the shank for cooperation with the reverse face of the panel [6.

On the obverse face of the panel l6 also is mounted the hub of the multiple spring contactor 39 including a plurality of resilient fingers 2%? in a different plane to that of the hub of said contactor. The fingers 20 are equal in number a? to the stationary contacts H and overlie the latter normally in spaced relation thereto but capable of being individually flexed into engagement with their respective stationary contacts.

The panel 16 with its contacts H and the multiple spring conta-ctor !3 are mounted on a suitable support 2| and are held in place by appropriate means 22, such as one or more nuts. The aforementioned parts are enclosed by a cover 23 in which are mounted a plurality of push buttons 24, equal in number to the contacts I! and the fingers 23 of the resilient contactor l9. Said push buttons 24 are arranged in juxta-position to the fingers for cooperation therewith to flex said fingers and cause them to engage their respective contacts I? as the push buttons are individually forced inwardly against the action of the fingers. Each push button has an indicating mark 25 thereon, preferably a numeral, and since I have shown the group of buttons and their associated groups of circuit closing elements as being ten in number the indicating marks are depicted as the numerals one to nine, inclusive, and zero. The cover 25 is detachably connected with the support H by a removable fastening means 26.

Certain of the contacts I! are connected in series by means of links 21 of electric conductive material which are of proper length to bridge a gap between two adjacent contacts and each link has a hole 28 at each end for registration with the shanks of adjacent contacts or with the shank of one contact and a screw 29, Fig. 3, which may fasten together the contiguous ends of two links, when said attached ends have been disconnected from a common contact H, for a purpose to be presently described.

The push button dial [5 is mounted in any suitable locality within an automobile, as on the steering wheel post, and has a master snap switch 30, Fig. 1, connected thereto and interposed in one of the controlling circuits of the electromagnetic selector unit.

A source of electricity 3!, such as the battery of an automobile, has one pole thereof, as the negative pole, connected by a conductor 32 with one side of the ignition system (not shown) of the automobile engine and thence to the other pole of the battery, as through a suitable ground, said other or positive pole of the battery being illustrated as grounded at 33.

The resilient multiple switch [9 is connected by a branch conductor 34 with the conductor 32. The conductors 32 and 34, in particular, are of the coaxial armored type, specifically illustrated in Fig. 4, wherein the electric conducting wire 35 is covered with an insulating jacket 36 and the latter surrounded by a coiled spring steel armor 3'! which is also electrically connected in the ignition circuit as represented by the ground 38.

The elect-ro-magnetic selector unit 39, Fig. 1, includes a suitable casing or housing 40 in which are located two tiltable mercury circuit makers and breakers 4! and 42 which can be identical in construction wherefore the description of one will suifice for a complete understanding of the structure and operation of both.

Each mercury circuit maker and breaker includes a hollow bulbous body 43 mounted on a crank 44 suitably journalled in the housing 40 whereby the rotation of said crank will oscillate or tilt the body 43.

At a suitable location in the body is one pair of complementary spaced terminals 45 and 46 which project outside of the body for connection with proper conductors. Also mounted in the body at a location, a considerable distance from the first pair of terminals, is mounted a second pair of complementary spaced terminals 41 and 48 which likewise project outside of the body for connection with proper other conductors. The body of each mercury circuit maker and breaker has, if desirable one or more baflles 43, Fig. '7, to provide one or more restricted passageways 50 for the flow of a quantity of mercury 51 in the body 43 from one location to another or from one pair to the other pair of terminals during the tilting actions of the circuit makers and breakers.

A pair of individual electro- magnets 52 and 53, Fig. 6, is associated with the mercury circuit maker and breaker 4| and similarly another pair of individual electro- magnets 54 and 55 is associated with or mounted in cooperative relation to the other circuit maker and breaker 42.

The pole pieces 53 of the individual electromagnets are appropriately shaped for coaction with the twin oscillating armatures each comprised of oppositely projecting armature leaves 51 and 58, one on each side of an armature pivot 59. Each twin oscillating armature has an arm or lever 60 as a unitary part thereof and said arm or lever has a longitudinal slot 6|, Fig. 10, for registration with the outer free end of the crank 44 whereby the oscillation of a twin armature will impart a similar or alternate tilting motion to the respective associated mercury circuit maker and breaker. To retain the armature structure and its respective circuit maker and breaker in either of the extreme tilted positions and assist in swinging them past the center during oscillation, a spring 62 has one end attached to the crank and the other end to the arm or lever to urge the crank outwardly within the slot 3| with relation to said arm or lever.

It is desirable that a three button combination be utilized for completing the ignition circuit and the complementary starter motor circuit in order to obtain seven hundred twenty combinations utilizing any preselected three buttons in each combination. Therefore, as an illustrative example, I have shown, Figs. 1 and 3, the links 21 disconnected from the contacts [1 associated with the buttons indexed 2, 6 and 9 and the ends of adjacent links which are disconnected from said contacts as being attached to each other by the fastening devices 29. This leaves all seven of the other contacts I! connected in series by the links.

A conductor 63 leads from the contact I! associated with button 2 to one side of the starter motor (not shown) and a feed conductor 64 leads from one side of the battery as through the ground 65 to one side of the master switch 30 and from the other side of said master switch leads a conductor 66, Figs. 1 and 6, to the terminal 4! of circuit maker and breaker 4| as an element of the electro-magnetic selector unit 39. From the companion terminal 48 leads a conductor 67, Fig. 6 to the terminal 47 of the circuit maker and breaker 42 while from the companion terminal 48 of said circuit maker and breaker 42 leads a conductor 68, Figs. 1 and 6 to the other sides of both the ignition system and the starter motor, said conductor constituting to common line to both said ignition system and starter motor.

Assuming that the contact I! associated with the button indexed 6 is one of those to be used then a conductor 6! leads from such contact to the terminal 45 and from the companion terminal 45 leads a conductor 1|, Fig. 6, to one p le of the electromagnet 52 while from the other pole thereof leads a conductor TI to the conductor 66 in which the master switch 30 is interposed. Where the other contact to be used is the one associated with button indexed 9, a conductor 12 leads from said contact to the terminal 45 of the second circuit maker and breaker 42 and from the companion terminal 48 of said second circuit maker and breaker 42 leads a conductor 13 to one pole of the clectro-magnet 54 while from the other'pole of said magnet 54 leads a conductor 14 to the conductor 51.

The dial circuit including the other seven contacts l1 comprised of said other seven contacts and their connecting links 21 is in communication with one pole of each of the electro- magnets 53, 55 through a conductor 15 and a branch conductor 16, respectively. For purposes of illus tration, the connection at the dial is shown as leading from the contact 11 associated with the button indexed 'I." The other pole of each o the electro- magnets 53, 55 is connected by a conductor 11 and a branch conductor 18 with conductor 51 which is common to both circuit makers and breakers 41, 42.

The illustrated apparatus is shown as set to operate upon the actuation of the buttons indexed 6, 9 and "2 in that order. When the parts are in neutral positions the master switch 38 is open or in the ofi position and the circuit makers and breakers 41, 42 are in the dotted line positions so that the mercury 51 is bridgin the gap between the terminals 45, 46 in both circuit makers and breakers 41, 42;

To complete the ignition and starter motor circuits, the button indexed 6 is pressed first which will complete a circuit from the positive side of the battery 3i via the grounds 33 and B5. conductor 64, master switch 30, conductors 6B and H, electro-magnet 52, conductor 10, the terminals 4G, 45 and the mercury of the circuit maker and breaker 4|, conductor 68, the contact t1 associated with the button indexed 6, the resilient multiple fingered contactor l8 and the conductors 34 and 32 to the negative side of the battery. This will energize the magnet 52 and attract the armature 51 to move the latter from the dotted line position, Fig. 6. to the full line position to tilt the circuit maker and breaker 4i and cause the mercury to flow away from the terminals 45, 46 and to the terminals 41, 48 of said circuit maker and breaker 4!.

The opening of the last above described net circuit will deenergize the magnet 52 to p vent the same from burning out and simultaneously partially close the ignition circuit from the positive side of the battery 3| via the grounds 3, i5, conductors 64, master switch 30, conductor terminals 41, 48 and the mercury of circuit maker and breaker 4i and conductor 51 to the terminal 41 of the circuit maker and breaker 42.

By subsequently pressing the button indexed "9 a magnet circuit can be completed from the positive side of the battery 3! via the grounds 33, 65, conductor 64, the master switch 30, conductor 56, terminals 41, 48: and the mercury of circuit maker and breaker 4|, conductors 61, 14, the magnet 54, conductor 13, the terminals 46, 45 and the mercury of circuit maker and breaker conductor 12, the contact 11 associated with h button indexed 9, the multiple fingered resilient contactor I9 and conductors 34, 32 to the negative side of the battery 3|. This will energize the magnet 54 and attract the armature 51 associatcdwith said magnet 54 to move the latter from the dotted line position to the full line position and tilt the circuit maker and breaker 42 to cause the mercury to flow away from the terminals 45, 46 and to the terminals 41, 48 of said circuit maker and breaker 42.

The opening of the circuit through the magnet 54 will deenergize the same to prevent it being burned out and will complete the ignition circuit, and partially close the starter motor circuit, from the conductor 61, Fig. 6, previously conditioned for carrying the electric current, through the terminals 41, 48 and the mercury of the circuit maker and breaker 42, through conductor 68 to the positive side of the ignition system and through the latter to the conductor 32 back to the negative side of the battery 3|.

The ignition circuit now being in condition for supplying current to the ignition system the engine may be operated. The closing of the positive side of the ignition circuit necessarily closed the same side of the starter motor circuit because it is common to both. By pressing the button indexed 2 said starter motor circuit will be completed from the positive side of the starter motor through the same to the negative Side thereof and'thence via conductor 63, the contact I1 associated with the button indexed 2, the multiple fingered contactor l9 and conductors 34, 32 back to the battery. Upon completion of the last mentioned circuit the engine will be turned over by the starter to start said engine. The button indexed 2 is held down as long as necessary or desirable for operating the starter and may be pressed as often as necessary without again touching the other buttons of the combination until such time as the circuits may be broken or neutralized.

Whenever the automobile is parked in a. public garage or parking lot the attendant may be shown which button to use for operating the starter and the master switch 30 turned off. This will open the ignition circuit and stop the en Thereafter, the engine may be started when desired by merely turning on the master switch and pressing the starter button which, in the example above described, is the button indexed 2.

When parking at night or on the street, for instance, any button other than those indexed 6, 9 and 2 is pressed which will open the circuits or neutralize the entire system. Assuming that the button indexed 5 is pressed then a circuit is completed through the contact l1 associated with said button indexed 5, the multiple fingered contactor 19, the conductors 34 and 32, the battery 3!, the grounds 33 and 65. conductor 64, masts switch 30, conductor 66, the terminals 41, 43 and the mercury of circuit maker and breaker 4!, conductors 61, 11 and 18, magnets 53 and 55, conductors 15, 16 to some one of the contacts 11, such as the one associated with the button indexed 7, the links 21, to the contact l1 associated with the button indexed 5. This will energize both magnets 53, 55 and attract their respective armatures 58 to tilt the circuit makers and breakers to open the ignition and starter motor circuits and condition the magnet circuits of the magnets 52, 54 for future operation as above outlined.

It will now be apparent that the three indexed button combination to which the dial is set must be operated in the exact sequence of the setting or the system will not function. When any one of the indexed buttons not used in the combination is pressed, purposely or accidentally, the circuits are opened and the engine will be stopped, if running, or prevented from being started. If one or two of the correct buttons are actuated and incorrect second or third ones pressed, the apparatus will not function and the actuation of an incorrect second or third button will immediately neutralize the system circuits. Therefore, any highly improbable progress an unauthorized person may have made in solving the combination by experimenting with the buttons without the consent of the owner will be nullified.

The dial can be set to operate on any one of seven hundred twenty, three-button combinations if ten buttons are employed in the dial and without using any one button more than once in the combination setting. The three-button combination can be readily changed by merely disconnecting cooperating links 21 from any one, two or three of the contacts I? and fastening the disconnected ends together by a screw 29, Fig. 3, and replacing any previously disconnected links on their respective contacts H.

Should anyone try to tamper with the installation by attempting to cut an armored conductor, the armor should thwart such an attempt but if successful in cutting through the armor, the tool will cause a short circuit through the armor 31 and conductor wire 35 which would neutralize the circuits in the selector unit 39 located in some rather inaccessible place in the automobile.

Of course I do not wish to be limited to the exact details of construction herein shown and described as these may be varied within the scope of the appended claims without departing from the spirit of my invention.
