Fig. 11 is a perspective View of an assembly embodying a portion of the present invention and comprising a bearing member, bracket, insulating disc and connecter carried thereby, and showing the relationship of a spring detent carried by the bracket, and operatively related to the bearing member for retaining the connecter in contact engaging position.

Referring to the drawings, it will be observed that the illustrative embodiment of the invention is shown in conjunction with a spark coil indicated as a whole by the numeral 15 and comprising a body portion of insulating material 16 having the usual electrical contacts 17 mounted thereon, and that the present invention associated with the coil comprises a housing indicated as a whole by the numeral 18 surrounding the body of the coil 15 and extending a substantial distance beyond one end thereof.

The housing 18, in the present instance, comprises a tubular member 19, a flanged collar 21 secured thereto by means of rivets 22, a relatively heavy ring 23 secured to the flange of the collar 21 by means of rivets 24 (Fig. 2) and a facing or finishing ring 26 secured to the ring 23 by means of screws 27 (Fig. 3), the flange ol' the collar 21 having ears 25 (Figs. 2 and 4) formed thereon for securing the device to a suitable support as, for example, to the instrument board of a motor vehicle.

Mounted in the housing 18, in spaced relation with respect to the adjacent end of the coil 15 and contacts 17 mounted thereon, is a bearing member 28 secured against angular displacement with respect to the housing 18 by means of annularly spaced projections 29 (Fig. 4) formed on the adjacent edges portion of the tubular member 19 and extending into annularly spaced notches or recesses 31 (Figs. 4 and 11) formed in the edge of the bearing member 28.

Rotatably mounted in the bearing member 28 is a hollow shaft 32 (Figs. 2 and 7) having, at one end thereof, a reduced portion 33 on which is mounted, at one side of the bearing member 28, a bracket 34 having a centrally positioned aperture formed therein to receive the reduced end portion 33 of the shaft 32, and having radially extending recesses into which a portion of the reduced end 33 is forced to provide a driving connection between the shaft 32 and the bracket 34 in a manner to insure rotation of the bracket 34 with the shaft 32, as clearly shown in Figs. 2 and 7.

Formed on the bracket 34 are a plurality of annularly spaced substantially parallel arms 36 adapted to be positioned in annularly spaced notches or recesses 37 formed in a disc 38 of insulating material (Figs. 2, 8 and 11) adjacent a centrally positioned aperture 39 formed in the insulating disc, the ends of the arms 36 being bent outwardly as indicated at 41 in Figs. 2 and 11 for securing the disc 38 against displacement with respect to the bracket 34.

Mounted on the disc 38 by means of fingers 42 engaging annularly spaced recesses 43 formed in the periphery of the disc 38 (Figs. 2, 3 and 11) is an electrical connecter indicated as a whole by the numeral 44 formed of current conducting material and provided with a plurality of spring fingers 46 having contact surfaces 47 formed thereon adjacent the free ends thereof and adapted for engagement with the contacts 17 of the coil 15. The connecter 44 is also provided with a centrally disposed opening or aperture 48 (Figs. 2 and 1l) adapted to receive the outwardly bent portions 41 of the arms 35 in a manner to space the arms from the connecter and to maintain the connecter completely insulated from the bracket 34.

It will be observed that by such an arrangement the connecter 44 is rigidly mounted on the insulating disc 38 in spaced relation with respect to the bracket 34, and that the resiliency of the spring lingers 46 serves to urge and maintain the contact surfaces 47 in engagement with the coil contacts 17 when in contact therewith.

Secured to the opposite end of the hollow shaft 32 at the opposite side of the bearing member 28 is a nn supporting member 49 having a laterally extending iin 51 (Figs. 3 and 4) mounted or formed thereon in radially spaced relation with respect to the axial line of said shaft 82, the fin supporting member 49 being secured to the shaft 32 by means of struck out portions 5() formed on the shaft engaging radially extending recesses formed in the member 49, as clearly shown in Fig. 2.

It will be observed from the foregoing description that as the 1in supporting member 49 and hollow shaft 32 are rotated in the bearing member 28, the bracket 34, insulating disc 38 and electrical connecter 44 will be rotated therewith in a manner to rnove the contact surfaces 47 of the connecter 44 into and out of engagement with the coil contacts 17 as clearly shown in Fig. 5 where the contact surfaces 47 are out `of engagement with the contacts 17, and in dotted lines in Fig. 8 where the conta-ct surfaces 47 are in engagement with the coil contacts 17.

For rotating the connecter 44 to move the contact surfaces 47 into engagement with the contacts 17 of the coil 15, a bearing or cam plate 52 is secured to the housing 18, preferably to the facing or icinishing ring 25 thereof by means of screws 53 (Figs. l, 2 and 8) and mounted adjacent the outer or exposed side of the plate 52 is a rotatable actuating member indicated as a whole by the numeral adapted to cover the screws 53 when in normal position, and having a laterally extending portion or trunnion 55 extending through a circular aperture 57 formed in the plate 52 clearly shown Fig. 2. At the opposite side of the bearing or cam plate 52 and secured to the laterally extending portion or trunnion 55 of the actuat" member 54 by means of a pin 58 is a beari 59 having a step portion extending radi y beyond the aperture 57 at one side of the plate 52 and having a reduced portion extending into the aperture 57 to obtain a bearing therein as clearly shown in Figs. 2 and 3. Mounted on the bearing disc 59 in radially spaced relation wih respect to the central or axial portion thereof is a stud or lug 61 positioned to overlap and engage the fin 5l on the fin supporting member 49, as clearly shown in Figs. 3 and 4, when the actuating member 54 and bearing disc 59 are rotated in a clockwise direction (Figs. l and 4).

ft will be observed from the foregoing description that with the parts described in their respective positions shown in Figs. 1 to 7, inclusive, and Fig. l1, the rotation cf the actuating member 54 in a clockwise direction indicated by the arrows 62 in Fig. 1, to position shown in Fig. 8, the bearing disc 59 by reason of the pin 58 will be rotated and the stud 81 mounted thereon, by reason of its engage-nent with one edge of the iin 51 on the nn supporting member 49, will rotate the hollow shaft 32, bracket insulating disc 38 and electrical connecter 44 and move the contact surfaces 47 thereof into engagement with the coil contacts 17 as shown by dotted lines in Fig. 8, thereby establishing an operative connection between the contacts of the spark coil. After establishing this connection and upon releasing the actuating member 54, the stud 6l, bearing disc 59 and actuating member 54 will be returned to their initial or normal position shown in Figs. 1, 4 and 6 by a spring 63 (Figs. 2, 3- and 6) having one of its end portions positioned in a socket formed in the hub of the bearing dise 59 as illustrated in Fig. 6, and its opposite end portion hooked around a bolt 64 mounted in the bearing or cam plate 52 (Figs. 2 and 6).

For retaining the contact surfaces 47 of the connecter 44 in engagement with the coil contacts 17 after the actuating member 54 has been released and returned to its normal or initial position by the spring 63, as above described, a

fiat spring 66 is provided and shown, in the present instance, as formed integrally with the bracket 34 and extending outwardly and laterally therefrom. The iiat spring 66 is provided at its outer free end with a detent or dog 67 adapted to enter and extend partially through a radially positioned aperture 68 formed in the bearing member 28 (Figs. 3, 4 and 11). When it is desired to disconnect the contacts 17, a release plunger 69, slidably mounted in an aperture 71 formed in the bearing or cam plate 52 and having its inner end portion extending into and partially through the aperture 68,` may be pressed inwardly by the operator in a manner to push the `detent 67 out of the aperture, after which a spring 72 (Figs. 2, 3 and 4) having one of its end portions extending through and secured to a lug 73 mounted on the 1in supporting member 49, and its opposite end secured to a bolt 74 mounted on the bearing member 28, will act to rotate the iin supporting member 49 and hollow shaft 32, thereby returning the bracket 34, insulating disc 38 and connecter 44 to their initial or normal positions, with the contact surfaces 47 out of engagement with the coil contacts 17 as shown in Fig. 5, the return movement of the parts being limited to a predetermined amount by a stop lug 76 carried by a portion of the bearing member 28 and extending into the path of a pair of laterally extending projections 77 and 78 formed on the bracket 84 as clearly shown in Fig. 7, the engagement of the projection 77 with the lug 76 serving to position the contact surfaces 47 of the connecter 44 between the coil contacts 17 as illustrated in Fig. 5.

For securing the device in inoperative position and against operation by unauthorized persons, a lock mechanism is provided and shown in the present instance as mounted in the actuating member 54. The lock member of the present structure includes the bearing or cam plate 52 having a concentric cam surface 79 and an eccentric cam surface 81 formed adjacent its edge portion, see Figs. 1, 2 and 8, the said cam surfaces being adapted to be engaged by the end portion 82 of an arm indicated as a whole by the numeral 83 and pivotally mounted intermediate its ends on a pivot pin 84 carried by the actuating member 54, the opposite end portion 86 of the arm being adapted to engage a rectangular notch 87 formed in one edge of a locking bar 88 slidably mounted in the actuating member 54 as clearly shown in Figs. 1, 2 and 10. A spring 89 is wrapped around the head of the pivot pin 84 and operatively related to the end portion 82 of the arm 83 and to a portion of the actuating member 54 in a manner to urge the end portion 82 of the arm toward and into engagement with the cam surfaces 79 and 81, as shown in Figs. 1, 2 and 10.

The slidable locking bar 88 is provided on its opposite longitudinal edges with a plurality of longitudinally spaced recesses or notches 91 adapted to receive lugs 92 formed on a plurality of tumblers 93 (Figs. 1, 3 and 9), certain of the lugs 92 being shown in Fig. 1 as normally out of engagement with the notches 91 and certain other of the lugs 92 being shown normally in engagement with the notches formed in the slidable locking bar 88 for controlling the position thereof to prevent unauthorized operation of the device.

For controlling the position of the tumblers 93, a plurality of push buttons 94, 95, 96, 97, 98, 99, 100, 101 and102 are slidably mounted in and positioned on opposite sides of the actuating member 54 and operatively related to the respective tumblers 93 by an annular groove and lug connection indicated at 103 in Fig. 9, the push buttons being adapted to be pressed inwardly against the action of springs 104 which normally hold the buttons in their distended or outward positions. It will be noted by reference to Fig. 1 that the lugs 92 of the tumblers 93 controlled by the push buttons 94, 100 and 97 are normally positioned in certain of the recesses 91 formed in the locking bar 88, thereby preventing a sliding movement thereof, and that by reason of the relationship and position of the pivoted arm 83 (Figs. 1 and 2) with respect to the locking bar 88 and the eccentric cam surface 81, any attempt to rotate the actuating member 54 in a clockwise direction (Fig. l), to move the contact surfaces 47 of the connecter 44 into engagement with the coil contacts 17, will be resisted by the eccentric cam surface 81, thereby preventing unauthorized operation of the device. It will be observed, however, that by pressing the push buttons 94, 100 and 97 inwardly, the lugs 92 on the tumblers 93 controlled by the push buttons 94.-, 100 and 97 will be moved out of engagement with their respective notches of the locking bar 88 and permit the bar to slide longitudinally of the actuating member 54 asV the end portion 82 of the pivot arm 83 is cammed or moved outwardly by the eccentric cam surface 81 and onto the concentric cam surface 79 when the actuating member 54 is rotated in a clockwise direction as indicated by the arrows 62 in Fig. 1, thereby permitting the actuating member 54 to assume the position shown in Fig. 8 and `moving the contact surfaces 47 of the connecter 44 into engagement with the coil contacts 17, after which as previously explained, the contact surfaces 47 may be maintained in coil contact engaging position by the spring actuated detent 67 engaging the aperture 68 formed in the bearing member 28, and upon releasing the push buttons 94, 100 and 97, the actuating member 54 will be returned to its normal or initial position shown in Figs. 1, 2 and 3 under the influence of the spring 63 in the manner previously described, and by reason of the end portion 82 of the pivot arm 83 being maintained in contact with the cam surfaces 79 and 81 by the spring 89, and the engagement of the end portion 86 of the arm with the rectangular notch 87 formed in the locking bar 88, the bar will be moved longitudinally to its normal or initial position, at which time, the springs 104 will act to move the push buttons 94, 100 and 97 outwardly in a manner to position the lugs 92 of the tumblers 93 associated therewith in the adjacent notches or recesses 91 formed in the opposite edges of the locking bar 88. A more complete description of the structure relating to the locking bar, tumblers and push buttons, and the operation thereof may be obtained by reference to my patent for locking device, No. 1,652,644, issued December 13, 1927.

If found desirable, the lock mechanism carried by the actuating member 54 may be rendered inoperative to secure the connecter 44 against rotation, as, for example, when parking the vehicle in a garage or the like, where it might be necessary for attendants to operate the engine of 'the vehicle, and for this purpose, a lever 106 is pivotally mounted on the cam plate 52 by means of a pivot pin 107, and is provided adjacent one of its ends with a hand crank 108 by which the lever may be readily rotated about its pivot, while the opposite end of the lever is provided with a laterally extending projection 109 adapted to eX- tend into the path of the actuating member 54 when the lever 195 is swung to the position illustrated in Fig. 8, thereby forming a stop for limiting the return or counterclockwise movement of the actuating member 54 as viewed in Fig. 8, and preventing the end portion 82 of the arm 83 rorn reaching a position adjacent the extreme lower end of the eccentric cam surface Sl. Such a limited movement of the member 5e and end portion 82 of the arm 83 prevents suicient longitudinal movement or" the locking bar 88 with respect to the actuating member 511 to en able the lugs 92 of the tuinblers 93 to enter the notches 9i of the locking bar 88 and thereby secure the bar against endwise movement.

It will be observed that by the arrangement described, the projection ille will prevent moveinent of the actuating member 54 to its horizontal, normal or lock fr position, but will permit movement of member 54 to an extent which Will permit the contact surfaces e7 to be disengaged from the coil contacts 17, and that a garage attendant, although not knowing the proper combination or buttons to be pressed in order to release the lock mechanism, may rotate the actuating member 5ft and contacts li7 into engagement with the coil contacts l'l, thereby enabling hir to operate the vehicle, after which the plunger` 69 may be moved inwardly to force the detent 67 out of the aperture 6o formed in the plate 28 and permit the spring 72 to rotate the connecter in a counterclocliwise direction (Fig. 8) and move the contact surfaces 47 out of engagement with the coil contacts 17.

.T t will be observed from the foregoing description that the present invention provides a novel construction and arrangement for operating a connecter and for sec rely locking the connecter against operation by unauthorized persons.

Obviously, the present invention is not limited to the recise construction and arrangement shown and described as tie same may be variously modiiied. Moreover, all they features of the invention need not be used conjointly as the same may be used to advantage in variously different combinations and sub-combinations.
