Referring to the drawings in detail the numeral 1 indicates the clock casing which is provided with the usual frame 2 for. receiving, the clock train as indicated in dot. and dashlines as shown in Figure 8. and this frame also has arranged therein and formedwith a sleeve keyed to the hour hand arbor, a gear: 3 which meshes with similar gears 4 and 5v disposed upon opposite sides thereof and mounted for rotation on. stub shafts 6 and '7 which includes p art of the settingmechanism of the switch actuating mechanismwhich will be presently described. The stub. shafts 6, and? are. each provided with knurled finger pieces 8 which. are secured to the. projecting ends thereof. as best shown in Figure 9. whereby these shafts can be rotated as will be readily apparent, and fixed to the shatt 6. is a dog, 9 while the shaft 7 has fixed thereto a dog 10. Secured to the stub shafts 6. and 7 are ratchets 11 whichare provided with. pawls 12 secured to the gears 4, and 5.

Pivotally mounted in the. frame 2 in a manner whereby their lower ends are. arranged in the path. of the rotation of the dogs 9. and 19 are arms 13: and 14 respectively. The arm 13 is provided with a rounded upper end which terminates in a substantially V-shaped' detcnt 15. While the arm 14;- is of substantially bell crank shape in configuration and also terminates in a substantially V-shaped detent. The lower ends of these arms 13 and 14 are held in the path of the dogs. 9 and 10v through Y stub. shaft21, and formed on theopposite end.

of said sleeve20 is a gear29 which is fixed to v a large disk 23 formlng one side Wall of a housing for a spring 24,. The oppos te, side disk25, which hiiormed therewith ahuh 2,6.

also having connection-with the spring 24: and

stubshaft. 2.1 as best shown in Figure-5. of the drawings. This last mentioned disk is pro.- vided with tongues 27 arranged circumferentially onone side thereofas shown in Figure. Land which cooperates with elongatedlsnd stantially rectangular shaped recesses 28 provided in a gear 22 which has formed there with the small disk 18. The stuh shaft 21 is provided with a linger "niece 30 whereby the spring be wound thereon .for a purpose which will be presentl described. Arranged upon opposite sides of the stub shaft 21 are arhors 31 and which have secured thereto pinions S3 and The pinion 33 meshes 'ith the 22, while the pinion 3% meshes with the gear 29 as host shown in Figure of the drawings. Each of these arbors 31 and have also secured thereto cam members 35 and 36 respectively which cooperate with studs 3? laterally extending from the sub tantial tl-shaped arm 38 formed on the switch operating member as best shown in Figure 10. lhe hod portion of this arm 38 is pi 'vidcd with slots through which pass screw bol 10 for sec 'ing said arm for slidahle moven i t o one 51 it portion of the frame 2, T 16 outer end of the arm terminates in a right angled bent portion 11 which has secured tiereto through the ir trumentality of a screw bolt- 2 an elongated insulating block 9 Uilt.

10 which as shown is circular in cross section and provided with a groove n formed in its upper surface. This insulating block ertends into a laterally disposed casing 45, fixed to the clock casng as shown Figure 3 and which has insularing material 16 arranged therein. The insulating material 16 is provided with a circular here to accommodate the block 13 as well as a metallic piece l? of circular cross section which is fixed to the block for n'lovement therewith as will be readily apparent. The insulating material is furth r provided. with aligned vertical bores through which pass binding posts 48 having their inner ends terminating in head 49 curred to follow the curvature of the ire of the insulating material and arranged in s a 'ed relation for pas age of the metallic piece in a manner whereby said piece will ch nge the heads for closing a circuit. Ari-air d in the aligned bores of the insulating material it; are coil springs 50 which re iii) the binding posts in their innermost positions for engagement with the metallic piece or the insulating block the case may be which will be readily apparent. The head it) of the upper binding post 18 is provided with :1. depending rih 51 disposed to be received in the groove 4+1 or a similar groove 52 which registers with the groove 44 as best show in Figure 10 of the drawings. v

The clock is provided with the usual dial 53 through which passes the arbor for the hour hand as well as the arbor for the minute hand as suggested in Figure 1 of the drawings, and arranged on the dial 53 are dials 54: and through which passes the shafts 6 and 7 respectively. Fixed to the projecting ends of these last mentioned arbors are hands associated with the numerals on the dials 5 1 and 55 which are provided with the words Oil and On respectively as shown. Fixed to the hour and minute arbors respectively are the appropriate hands for cooperation with the numerals of the dial f8.

The circuit for the switch is disclosed in Figure 11, and extending from one of the binding posts 48 is a conductor 56 having electrical connection with a parking lamp 5? in the present instance, and also electrically connected to the parking lamp is the opposite conductor 58 which is connected to a source of electrical energy 59 from which extends a conductor 60 connected to av conductor 61 having its ends electrically connected to the op posite binding post and to one side of a manually control switch 62, while the opposite side is electrically connected to the conductor 56 through the instrumentality of a conductor 63.

From the above description and disclosure in the drawings, it will be obvious that I have provided a time controlled switch that is adapted to operate at predetermined times for illuminating and extinguishing lamps, and in the present instance the switch is shown in circuit with a parking lamp of an automobile as shown in Figure 11, and if it is desired to have the switch illuminated ata certain time, the shaft 7 is rotated for p0- sitioning the hand thereof with respect to the numeral on the dial 55, it depending of course what time it is desired to illuminate the parking lamp. For instance, if it is desired to illuminate the parking: lamp at four oclock, the switch 62 is closed and the hand of the arbor 7 is set at four oclock as shown in Figure 1, and if it is desired to extinguish the parking lamp at seven oclock the hand of the arbor 6 is set at seven oclock as shown. Of course, the spring 2 1 is wound about its shaft 21 through the medium of the finger piece 30. hen the gear 3 rotates the gear 5 of the shaft 7, to arrange the dog 10 for engagement with the arm 18, the dog will move the detent- 15 out of the V-shape notch of the disk 18 and therefore release the same so that the spring 24 will rotate the gear 22 which will in turn rotate the gear 33 and cause the cam member to engage the adjacent stud 37 and slide the arm 38 as to position the metallic piece -11? in contacting engagement with the binding posts 48 as shown in Figure 3 of the drawings an d thereby closing the circuit to the parking lamp 5?. The switch will remain closed until seven oclock at which time the gear 3 will. have moved the gear t in a position so that the dog 9 will engage the arm 14 for moving the detent 15 thereof out of the l-shape notch of the disk so that the spring 24: will at that time rotate the gear 29 which meshes with the gear 34 secured to the arhor 32 and this 'arbor will cause the cam i'nember 36 to engage the adjacent stud 37 of the arm 38 and posilihj tion' the metallic piece out of engagement with the heads of the binding post and arrange the insulatingblock between the heads 49 and thereby open the circuit to the parking lamp. From the above description, it will be further seen that the spring will operate either of the gears 22 or 29 alternately as each are secured to the spring as set forth.

The detcnts prevent movementof the disks 18 and 19 until the detents areentirely removed from the V shaped notches of these disks'by the dogs 9 and 10 which are ar ranged so as not to entirely remove the detents until the dogs snap off the ends of the arms 13 and 14. The detents allow. only one revolution of the disks 18 and 19, as the springs 16 for the arms 13 and 14 force the detents back into the notches after such revolution The gears 33 and 34, are rotated by the arbors 31 and 32 which have secured thereto the cam members 35 and 36 as set forth. The cam members are providedwith curved and straight surfaces as best shown inFigure 3 of the drawings, and are arrangedwhereby the surfaces will be disposed in opposed re lation with respect to each other, with the result when one cam member has moved the switch arm by the engagement of the curved surface thereof with its stud 37, the straight surface of the other cam member is arranged so as to allow its stud to pass toward the curved surface of this last mentioned cam member so that this stud will be arranged in the path of the curved surface of its cam member for reversingthe movement of the switch arm when the last mentioned cam member is moved by its arbor.

It is thought from the foregoing descrip tion that the advantages and novel features of my invention will be readily apparent.
