This invention relates to time controlledA mechanisms, and. aims to provide novel means whereby the circuit to aparkinglight will be completed to light the parking light' at the proper time in the'evening and to break the circuit 4to cut off the light' at the proper time in the morning.

ftrating .the contact ring members in circuit witha source of electric supply.l

`Referring to the drawing in detail,- the reference 'character 5' designates aclock lor a jconstruction especially designed for 4use. on

motor4 vehicles and the type usually sup-. ported in the instrument board of the motor vehicle. The attachment forming the essence of theinventonfincludes a supporting band 6 which isconstructed 'to -be slid over the body portion o the clock ,casing adjacent to the y face of the clock as clearlyshown'by Figure I- Mounted within .the supporting `band 'is :a ring member 7- of a diameter to closelyV t within the band 6,`the ring member 7 being under surface, the contact ring 8 engaging the right angled end 9 of the contact arm 10 of the motor vehicle, is connected.

On the upper surface of the ring member 7 isa contact 'ring segment 12 which is in 8 through thering and ring segment together, it being structed of brousor other insulating masupplied'with a contact ring 8 'secured to its*t understood' that the ring member 7 is con- Forming a part of the member` 7 a' finger-piece 14 that extends through a slot formed in the supporting band 6 so that a person may operatethe ring member 7 to adjust the same, 1n a manner to be hereinafter l'more fully described.

The reference character 15 indicates the outerring member which is-.also constructed of insulating material, the same being supplied with a contact ring 16 securedl to the under surface thereof, the contact member 16 resting on the contact ring segment 12 to receive current therefrom. Pins 17v pass through the contact ring member -15 and contact ring 16, where they connect with4 the contact segment 18 providinga circuit therebetween.

As clearly shown by Figure 2, the under portion of the ring member 15 'is cut away throughout a portion of its diameter so that `the hour hand 19 of the clock'may rest on the contact segment 12.

e member 22-Will swing from' a position 'asshown by Figure 7 to a yposition as shown The ringmember is also. providedwith a groove formed -intermeoliate lits thickness, ,there being provided aguiding finger 21 atthe entrance of thegroove forguiding the hour hand into the groove, 'astliefhouI-.

hand moves in the'usual; mannen At theopposite end of the 'groove 20 is a -rpivoted member 22,-which, is formed with ,a groove 23; forming-a. continuation of the groove 20 'so that as the hand passes through the groove 20 and onto the-member 22, the

by Figure 6 spanning" the space24 to guide the hour hand 19 onto the upper surface of the ring Vmember 15 where the circuit 4is broken. A l

As clearly shown by Figures Gand 7 of I the drawing, the member 22 is pivotally sup,-l

' struction, an adjustment of the lowermost" ported at 25 and i's normally held in a position as shown by Figure 7, or' in a position to be engaged by the hour hand, by means ofthe spring member 2 6, which bears thereL against.

A finger piece' indicated at 27k forms a part of the ring member .15 vand also passes through a slot inthe supporting band .6 so

that this ring ,member ma be adjusted with respect to' the ring 4mem er 7, to vary the time at which .the circuit is'made or broken.

The space 24- which is formed at one end of the contact segment 18,' is' formed' by cutting a notch through' the ring member 15 and-provides means whereby the hour hand may spring back onto the contact seg ment 12 of the 'ring member Z after it has 'passedfrom the contact segment 18., v

Thus it will be seen that due to this conring member may be made so that a greater or less portion of the segmental contact 12 may be provided at the end of the segmental contact 18 to cause the circuit to be closed a greater or shorter length of time.

The lamp is indicated by the reference `character 28 and is in circuit with the ring the main portion of the ring member 7,

breaking the circuit to `the lamp lt 1s obvious that by moving the finger piece le, the ring member 8 may be adjusted to cause the circuit to be broken at, for example five oclock in the morning7 and that by moving the outer ring member 15, the ring member-may be adjusted so that the,V hour 'handwill contactlwith thedsegg The wire 33;-vv ichconnects-withthe ter-'- minal-B, is incircuit'withthe hour hand the .circuit may"A be vctnnplete'd astlie hour 4hand moves over the lse'gme1'1talcontacts,

. 'Assumirigtlattheclock hasbeen set as shown byl Figure 1,',thehour hand moves overthe se'gn'uentalcontactbll completing the circuitv to the lamp as longas theV hour hand engages the segmental contact-18. As

the hour hand lmoves "to, the .upper'endof the segmental Contact 18; and passes into the the space 24 contacting with the segmental 80 `space24,fthe hour 'hand will rmove through contact 12 `which is disposed directly-thercnnder, where the circuitY isagain completed to the lamp, the circuit remaining completed until the hour hand moves ol' ofv the Contact segment 12 at the lower end thereof.

As the hour hand continues to rotate, it will be seen, that the hour hand passes up over the-,member 21 contacting with one ."wall ofthe groove4 of the ring member 15. l whereupon the circuit remains broken. The

hour hand 'continuing to rotate in a clock-4 Wise direction, moves over the member 22 causing the member 22 to swing to a positionjas shown by Figure 6 whereupon the hour hand moves onto the upper surface of the ring'lm'ember 15 until it .contacts withy the segmental contact member 18, whereu pon the circuit is again completed to light t e light.

From the foregoing it will be obvious that the operation is automatic and will Acontinue to light and cut 0H the light atpredetermined intervals, to the end that lthe parking lamp of a motor vehicle may be automati cally lighted in the evening, and automatically cut off in the morning.

We claim: l. In combination with the hour hand of a clock, a switch including upper and lower ring members mounted for rotaryv movementI over the face of the clock, said ring members being constructed of fibrous materiah, a

segmental contact member carried by each ring member, one osaid ring members having a groove, means for' guiding the hour hand from one of the contact segments into the groove, and means for directing the hour hand from the groove to the upper surface of the ring member supplied with the groove. l

2, lln combination with the hour hand of a "clock, a switch including ring members formed of insulating Amaterial supported adjacent to the face of the clock, a segmental contact member carried on the upper surface oi each ring member, a circular contact member on'the under surface of each ring membei', means for completing a-circuit to the i circular contact member of one of the ring members, the circular contact member of the opposite ring member resting on the segmental contact of the first mentioned ring member yto complete the circuit to the segmental contact member of the second mentioned ring member, and means for directing the hour hand from one segmental contact member to the adjacent segmental contace member to complete a circuit.

3. In combination with the hour hand of a clock, a switch including outer and inner circular contact supporting members mounted adjacent to the face of the clock and over which the hour hand moves, said Contact supporting members having Contact members I formed thereon, the outer circular contact supporting member' having a notch to permit the hour hand tov pass from the Contact member of the outer Contact fsupporting member to the contact member of the inner contact support-ing member, said hour contact supporting member having a groove, a pivoted member at one end of Athe groove and` adapted to swing over' the notch to permit the hourl hand to pass over the notch and onto the contact supportingV member.

In testimony that we claim the foregoing as our own, We .have vhereto affixed our signatures.
