WILLIAM G. MAB/ROW, OF'NARRAGANSETT PIER, BJ-IOIDE ISLAND, AND JOH N M. BIDDLE, OF WASHINGTON, DISTRICT OFCOLUMBIA.

' TIME-CONTROLLED SWITCH FOR ELECTRIC LIGHTS.

To all whom it may concern:

Be it known that we, WILLIAM C. MAR- now and JOHN M. BIDDLE, citizens of the United States, and residents, respectively,

of Narragansett Pier, in the county of Washington and State of Rhode Island, an of Washington, in the District of Columbia,

have invented new and useful Improvements in Time-Controlled Switches for Electric Lights, of which the following is a specification. 7

Our invention relates to time controlled switches for electric lights, and pertains more particularly to means for automatically lighting the electric lamps of automobiles at a predetermined time.

j The object of our invention is to produce a device for automatically lighting electric lamps at a predetermined time.

A further object thereof is to produce a device attached to an alarm clock of conventional form adapted to be set for automatically closing the electric circuit from a suitable source of supply for lighting elec- Y tric lamps at a predetermined time, and a still further object thereof is to produce amore simple, cheap and efiicient device of said character than has heretofore been attained.

To these ends, and for others as will hereinafter appear, our invention includes the combination and arrangement of component parts tobe herein described and more particularly pointed out in the claim.

In the accompanying drawings in which like reference characters indicate .similar parts, Figure 1 is a diagrammatical plan view of our invention applied to an automobile; Fig. 2 is a front" view ofour clock and circuit closerattached thereto; Fig. 3 is a top plan view of the time controlled escapement for actuating the circuit closer;'Fig. a is atop plan view of our circuit closer and electrical contacts; Fig. 5 is a back view 01' our clock controlled switch actuating apparatus and circuit closer; Fig. 6 is a transverse sectional view of our circuit closer taken on the line 6-6 of Fig. 4, and. Fig. 7 is a detail perspective view of the switch plate carried on our circuit closer.

Referring now to the drawings, thenumerals 1, 2 and 3 designate electric lamps connected with the circuit wires A and B leading from a source of supply C. The circuit wires, as shown, are broken and attached to the posts 4: and 5 adjacent to each Specification of Letters Patent. P m t a S t, 21,1 15

other and of conducting material, which posts are adapted to be electrically connected and disconnected to illuminate and darken the lamps as hereinafter described.

Our apparatus for connecting and com- -pleting the electrical circuit between'the posts 4: and 5 comprises the plunger 6 car ried in'the lateralcase-7 attached tothe 'case a longitudinal slot in the lateral case 7 and bearing against its inner wall.

As shown in the drawings, the inner end of our plunger is adapted to be engaged and pressed outwardly by the spring actuated pivoted finger 12 mounted on the frame 13 of an alarm clock of conventional form. Said finger is provided with a notch 12' adapted to engage one end of the pivoted trigger 14 to hold the finger out of contact with the plunger when the electrical circuit is open, which trigger is adapted to be tripped by the rotation of the cog wheel 15 connected with the opposite end of the trigger l t by the rod or pitman 16 eccentrically attached to the cog. Said cog 15, as shown, is mounted on the clock frame and meshes with the idler cog-wheel 17. The latter wheel 17 is adapted to be engaged by and mesh with the wheel 19 when the latter wheel 19 is moved outwardly at a predeterminedtime at which the mechanism controlling said cam may be set. The means for actuating said wheel 19 are of conventional form, and as they form no part of our inven- 4: and 5, by which action the finger 12 is 110 sot a clock 9. Said plunger is preferably pushed backward to engage the trigger 14:- The clock mechanism may be set for release at a desired time, the action of which Will trip the trigger 1i and allow the springpressed finger 12 to move the plunger out Wardly and contact the switch plate with the poles 4: and 5, and thus complete the electric circuit through the lamps connected therewith.

Having thus described our invention, What We claim as new and desire to be secured by Letters Patent, is

A mechanism for making electrical contacts comprising a pair of fixed contacts, a slidable bar having a switch plate therein adapted to contact with and close an electrical circuit through said fixed contacts, clock mechanism, a spring-actuated finger for moving said bar and switch plate into closed contact with said fixed contacts, a trigger for holding said finger out of actuating contact with said movable switch, a normally dormant gear on said clock mechanism connected With said trigger, and means connected With the clock mechanism for actuating said trigger actuating gear at a predetermined time. 7
