JOHN B. ALBERT, OF BRIDGIEPORT, CONNECTICUT.

IGNITION-SWITUH LOCK FOR AUTOMOBILES.

Application filed August 31, 1923.

To 017 whom it may concern.

Be it known that 1, JOHN B. ALBERT, a citizen of the United States, residing at the city of Bridgeport, county of F airfield, and State of Connecticut, have invented certain new and useful Improvements in Ignition-Switch Looks for Automobiles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap' aertains to make and use the same.

This invention relates to an ignition look for automobiles, but more particularly has reference to the peculiar structure and operation of a permutation locking mechanism whereby the ignition circuit may be opened or closed at the will of the operator.

Another object of the invention is to prevent theft of an automobile by driving it while operating by its own power and ignition system.

Furthermore, the invention aims to provide a simple but eiiicient mechanism for bringing about the desired results.

In the accompanying drawing Figure is a front elevation of the improvement as it appears when in position for use.

Figures 2 and 3 are detail elevations of opposite sides of one of the combined bush ing and auxiliary disk structures.

Serial No. 660,285.

Figure 12 shows diagrammatically the ignitition circuit, and

Figure 13 is a section at the line 13-13 of Figure 11.

Similar numerals of reference denote like parts in the several figures of the draw- 111g.

1 is a frame within which the various parts are assembled. 2 is a shaft journaled in the front of the frame and in the back plate 3 of the frame, and 4c are bushings loosely supported around the shaft and capable of free rotation.

Each of these bushings has rigid therewith and at opposite ends hubs 5, (5, from which extend respectively straight and hook fingers 7, 8. Loosely supported around each bushing is an auxiliary diskfi, and between the side faces of this disk and the hubs 5, 6, are concavo-convex spring washers 10, and the ends of the bushings are crimped inwardly. so as to clamp these washers with considerable friction against the disks 9, so that it will be clear that the bushings may be revolved independently of the disks, provided the latter are hold stationary, while the entire structure may be revolved if the disks are released.

There are as many of these combined bushings and auxiliary disks as desired, but four of them are shown in the drawings this number being quite sufficient.

Secured to the rear portion of this shaft so as to always move therewith is a master disk 11 which has extending from its outer face a stud 12.

The hook fingers above specified. are at the front endsof all the bushings with the exception of the outermost bushing, while the straight fingers specified are at the rear ends of all the bushings. In other words, each auxiliary disk is fianked by straight fingers at the rear and hook fingers at the front with the exception. of the outermost auxiliary disk in the instance of which. latter there is no finger whatsoever in front ofthe disk because it is not necessary as will be obvious.

From the foregoing description it will be clear that when the shaft is revolved, the stud 12 of the master disk will strike the straight finger of the innermost disk and revolve the latter which will cause the hook finger of this disk to contact the straight finger of the next disk and revolve that disk also, and so on, so that each disk will be successively picked up and revolved.

It will likewise be clear that if the auxiliary disks are all held stationary during this revolution of the shaft then the bushings themselves will be successively revolved.

Each auxiliary disk has in its periphery a gate 13, and in the periphery of the master disk 11 is a gate 14 one wall of which is beveled for the purpose hereinafter explained.

Pivoted around a cross pin 15 extending through the frame is a lever 16 from which depends a dog 17 one face of which is beveled and the other straight, said dog adapted to enter the gate 14 in the manner and for the purpose hereinafter to be explained, and likewise pivoted around the cross pin 15 is a lever 18 which is bent at right angles to form a cross bar 19 that extends immediately above the disks 9, the free end of this cross bar being secured to the lever 16, so that it will be clear that the levers 16, 18, and the cross bar 19 constitute a skeleton frame which is pivoted around the cross pin 15. v

Pivoted to the free end of the lever 16 is a vertically disposed bar 20 of insulating material, and pivoted to the lower extremity of this bar is the front end of a switch 21 the rear extremity of this switch being pivoted within a block 22 of insulating material.

23 is a terminal of the ignition circuit which terminal is secured upon the insulation block 22, and this terminal is likewise included in the circuit for the self starter, these circuit connect-ions being quite ordinary but being more specifically referred to hereafter.

The rear or pivoted endof the switch 21 is electrically connected in circuit with the battery as will hereafter be more particularly referred to, so that it will be clear that when the switch structure, which includes the switch proper and the levers 16, 18, cross bar 19, and insulated bar 20, is elevated, theignition circuit will be broken, and when said switch comes in contact with the terminal 23 said circuit will be closed.

24 is a coil spring which surrounds the cross pin 15, one terminal of which spring is elongated and bears on top of the cross bar 19 while the other terminal bears upon the frame 1, the function of this spring being to always urge the switch structure toward the auxiliary disks 9, so that the cross bar will, when the gates of the disks are alined, enter these gates and cause the switch to contact the terminal 23.

25 are brake shoes having extending therefrom pins 26 which latter pass loosely through the frame, and 27 are coil springs around the pins and between the frame and shoes the function of these springs being to always urge the shoes into contact with the peripheries of the auxiliary disks with sufficient pressure to prevent the rotation of these disks except when the latter are driven positively.

28 is a dial having an upward extension 29 within which is secured, as by soldering or otherwise, a socket 30 for the electric light.

The shaft 2 extends concentrically through the dial and has affixed to its outer end a manipulating knob 31 which carries an index 32. 1

33 is a small electric light secured within the socket 30 and electrically connected by a conductor 34 to a. terminal 35 which latter is secured to the insulation block 22.

36 is a switch lever pivoted around the shaft 2 and having its lower extremity extending within a recess a in a block 38, which latter has on its lower face a shoe 39 made of some good conductor of electricity which shoe has a toe portion 40 that forms the front face of the block. 41 is a plate like wise made of a good conductor of electricity and fixed upon the floor of a cut out portion 37 of the block 22 immediately beneath and always in contact with the shoe 39, and this plate has a flanged portion 42 which extends against the inside wall of said recess.

43 is any suitable conductor extending from a battery and connected to a terminal 44 that extends within the insulation block 22 and is in contact with a conducting pin 45 which is also in contact with the flange 42, so that it will be clear that the plate 41 and consequently the shoe 39 are always in the battery circuit.

46 is the pivot pin of the switch 21 and this pin is made of a metal of good electrical conductivity and extends through the insulation block 22 into contact with the terminal 44 so that it will be evident that the switch is likewise in circuit with the battery.

Extending from the upper extremity of the switch lever 36 through an arcuate slot 47 in the dial plate is a. stud 48 to the outer extremity of which is aflixed a thumb piece 49, whereby the switch may be swung to and fro on its pivotal point so as to throw the block 38 with its toe 40 in contact with the terminal 35, or to slide the block so as to separate said toe and terminal, as the case may be.

Extending from the terminal 23 is an electrical conductor 50 which goes to the ignition and from the latter to one pole of the battery, the conductor 43 leading to the other pole, and 51 is an electrical conductor extending from the terminal 23 to the self starter and thence to the ignition.

Of course, it will be readily understood that the exact circuit as shown is immaterial since it may be varied as to details. The

diagrammatic View at Figure 12 will clearly show the various circuits.

The provision of the electric light is merely for the purpose of enabling the operator to see the dial in the night time and this latter has nothing whatever to do with the construction and operation of the parts nec essary in practicing the invention.

In securing the parts to the dash A of an automobile, an opening 52 is cut in the dash and the frame inserted therethrough from the front, the socket 30 being simultaneously inserted through a suitable opening 53 likewise cut in the dash. A cover 54 is then placed over the parts from: the inside and secured by means of screw bolts 55 driven through the dial plate and cover and engaged with nuts 56 at their free ends.

But it is really immaterial how the device is secured to the dash since it is quite understandable that the mere seourement of the device is a matter that may be varied according to the desires of the user.

In changing the combination, the gates are first brought into alinement by the manipulation of an old combination, which latter causes the switch structure to enter the gates in the manner hereinbefo-re described. A key 57 is then inserted through perforations 58 that are in each auxiliary disk and which have been alined simultaneously with the alining of the gates.

Referring to Figure 7', the key is shown-inserted within the perforations in the auxiliary disks, only one of these perforations, of course, appearing, and the key is provided with an elongated bit 59, which, in this Figure of the drawings, is positioned immediately preparatory to the turning of the key so that this bit will strike against the lever 16 and thereby elevate the switch structure free of the gates in all of the disks.

The key is inserted through a suitably shaped key hole- 60 which is out both in the back plate 3 and in the cover 54, and the major portion of the length of the key con sists of a circular rod as shown more partic ularly at Figure 9, while the bit of the key projects from the rod, so that when the rod portion of the key has been inserted through the perforations in the auxiliary disks, the bit will be immediately beneath the lever 16, so that when the key is given a quarter turn the bit will operate toraise the switch structure in the manner before explained.

After this operation of the key the master disk will be free and can be revolved while the auxiliary disks will all be held stationar by the key itself. I

caring in mind that the auxiliary disks are friction tight on the bushings, the knob 31, is then manipulated, thereby causing the stud 12 of the master disk to strike the straight finger of the rearmost bushing so to revolve the latter, and during the revtit olution of this bushing its hook finger will come in: contact with the straight linger of the nextbushing and revolve the latter also whi.v will cause the hook finger of the same to strike the straight finger of the next hushing and likewise revolve it and cause the hook finger of this last named bushing to strike the straight linger of the outermost bushing and revolve the latter.

The operator manipulates the knob 31 any desired number of times toward the left and stops with the index 3.2 opposite the desired number on the dial. This determines the relative positions of all" the fingers when the index is registered in this manner.

The operator then turns a desired number of times to. the right, which wiil cause a similar revolution of the bushings, and stops with the index registering with any suitable number on the dial, and this operation is continued according to the number of permutations desired.

this setting of the combination above described the gates in the auxiliary disks will be held in alinement by the key, and the cross bar 19 will beimrnediateiy above these alined' gates, while the dog 17 will be supported on top. of the periphery of the master disk.

After a combination has been obtained in this manner the operator withdraws the key, but the switch structure will not enter the gates so. as to edect contact with the terminal 235 because such structure is held in elevation owing to. the fact that the dog 17 is resting upon the periphery of the master disk 11,. but when this disk is turned either tor the right or to the left, as the occasion may demand, until thegate 14: comes be neath the dog, the switch structure will drop and contact of theswitch with the terminal will then be effected.

When the owner of the car wishes to. render the latter safe as against theft he ma nipul'ates the knob to the right, thereby throwing the dog 17 out of the notch 14 and thus elevating the switch structure and cansing the gates in the auxiliary disks to. be thrown out of alinement.

When the car owner again desires to use his car he manipulates the same combination, heretofore determined by the rotation of the bushings, which will again bring the gates in the auxiliary disks all in alinement below the cross bar 19', and he then turns the master disk tov the right or left untit the dog 17 enters the gate 14.

Should the car owner desire to manipulate the combination at night he merely operates the switch lever 36: to close the circuit for his light in the manner above described.

In the manipulation to arriveat a combination the permutations of which have already been obtained, the auxiliary disks iii;

will be revolved with the bushings owing to the frictional union between them, but none of the auxiliary disks can be revolved except when such revolution is brought about by the contact of the stud of the master disk or the contact of hook fingers with straight fingers, because the bearing of the brake shoes will prevent any revolution of the auxiliary disks except by positive means.
