ELECTRIC SWITCH.

Specification of Letters Patent. Application filed October 4, 1913. Serial o 798,321.

Patented July .21, 1914.

To all it may concern: Be 1t-'-'-l'rnown that I, RISAKU Ismail-um, a subject of the Emperor-of Japan, residing at Seattle', .in the county of-King and State of Washington, have invented certain new and useful Improvements in Electric Switches, of which following isa specification. This invention relates to improvements in electriciswitches, and has for its object the provision of time controlled devices for actuating; said switch'at. any predetermined hour and, minute of. the day.

r;-."The'apparatus may be employed in any situation where a time-controlled switch is desirable but it is articularly applicable for automobile use in ighting the sideand taillights thereof where the car is left standing in; an. exposed. position, as in a street, and it.

isinconvenient for the owner to be present to turn on. the lights.

In the present drawings is illustrated an embodiment of my invention particularly adapted to automobile service.

- With the "above objects in view, the invention consists in the novel construction of an electric switch and the combination and adaptation therewith of time-actuating devices, as will be fully explained in the following specification, illustrated in the accompanying drawings, and finally set forth:

in the pended. claims.

In said drawings, Figure 1 is a view intront elevation of an embodiment of my inviews of. the same with the switch elements shown in open and closed positions, respectively, Figs. 4 and 5 are .detached detail? perspective views of elements of the invention.

Referring to said views, the reference numerals 2 and 3 designate front and back walls, respectively, of a casing, including an upper vertically arranged switch compartment 4 and a lower motor compartment 5.

Said compartment d is lined on its rear side and bottom dividing the two said compartmentswith-insulating material 6 in which are fixedl positioned terminals 7 and 8, respective y, of an electric circuit A plunger 9 of non-conducting material 1s arranged for vertical reciprocatiive movements.-

copper or other good conducting material is ing its lower end 10 extended forwardly below sald plunger in vertical alinement with bridge to close the gap between said-terminals when the plunger is in its lowermost position. Terminal 7 includes a leaf 7 resiliently. protrudinginto the path of said plunger while end 10 of the bridge strip 10 is curved to afford yielding electricalconnec- 'tions at the respective oints. A vertically lower end to said plunger and slidably ex-. tends through an aperture in the top of the casing 1 where it is provided at its extremity withv a knob 11 An extension spring 12 is coiled about said stem within compartment is secured at one end in a recess at one side of said compartment 4 and formed at itisflpposlte end with a convex port-ion 1-3.}I wh'ich in said plunger for yieldingly securing the plunger in ill-operative condition in the upis fitted having its dial. 19 at actuate the trigger aforesaid. Thespindle vided with a gear-wheel 21 which communicates its rotary motion through intermediate gear-devices 22 to agear wheel 23 integral with a, hub 2d rotatably mounted upon a mandrel 25, see Fig.5. Said mandrel is provided at rearextremity with a squared arranged stem 11 is rigidly secured at its is adapted to engage within a depre's's'ion 14 16. Said members are hingedly con- W'thin said motor compartment the fnontotnflie. casing.

Strip 10 thus serves as a 4- having its ends bearing upon sald-casing. top and the plunger, respectively, tendin to press the latter downwardly. A flat-spring 13 per portion of compartment 4, as indicated end 26 to accommodate aturning key (not shown) and at its frontend extends outside of said dial 19 where it is provided with a pointer 27 in connectionwith a minor dial :28 upon said dial face 19. Within said compartment 5 a pin 29..projects at right angles from said 'mandrel and coacts with a cam face 30 upon the forward end of said hub 24:. -Member 15 of said trigger is secured at 15 to the frame of the clock and extends,

-jum' s outward under the pressure exerted by t e spring-member 15. he latter similarly springs outwardly and such movement causes the tripping of the plunger thereabove, as will be present-1y explained The continued rotation of the hub causes the pin to-wipe upon the inclined portion 33 and, by reaction, thrust; the hub and member 15 inwardly to their original position.

The ordinary inoperative position of the device is indicated in dotted lines in Fig. 2 with the spring 13 engaging the depression 14 holding the plunger in its uppermost position. hen it is desired to pre-arrange that the lights shall be turned on at a given time, the mandrel 25 is adjusted until the pointer27 indicates the selected hour upon the minor dial '28. The plunger 9 is then pressed downwardly out of engagement with said spring-l3 until it rests upon the wing 16 of the trigger, being then as shown in full lines in Fig. 2. At the proper time, the rotation of the spindle 20 by the clockwork similarly rotates the hub 24 bringing the notch 33 into register with the pin 29. As aforesaid, the trigger member 15 is then released and draws forwardly sufliciently at its upper end, as indicated in Fig. 3, to release the plunger which descendsthrough force of its gravity and the spring 12 bridging thetwo terminals 7 and 8 completing the circuit A an'd lighting the lamp or lamps thereon. The continued rotation of the hub 24 and the spring-pressed engagement of the pin 29 on the inclined portion 33 of said cam-face causes the spring member 15 to recede to its original and normal position withthe wing lfiprojecting within said compartment 4 in the path of the plunger. Should the plunger be in its lowermost position wherein saidelectric circuit is closed when said wing is reenter-ed within the cas lines in Fig. 3, through its engagement with said depression 1st and a spring 34 is provided at its connection with the member 15 to return the wing to its normal horizontal position as soon as the interference is withdrawn. The plunger is desirably rovided with a roller or other anti-friction evice 35 at its forward lower edge where it is supported by said wing 16 whereby the force required to withdraw said wing when suitably actuated is reduced to a minimum.

'The lights are extinguished by raising the plunger to its elevated inoperative position, or they may be turned off by a snap or other suitable switch (not shown) in a three-way system of wiring. In the present example, the circuit A is shown including a battery B and a lamp C while D indicates a supplementary circuit having a switch E whereby the lamp may be lighted independently of the time-controlled devices shown. Also itwill be understood that while I have described my invent-ion as a unit it may be duplicated or units included to correspond to the requirements of the user. It is found usually desirable to provide separate switch devices for the side-lights and for the taillights of an automobile, hence in the illustrated embodiment the apparatus is shown in Fig. 1 as including duplex switch devices designated by the same or corresponding reference numerals and operated by the same clock-mechanism. Thus the member 15 is shown branched at its upper end and supports two elements 16 and associated parts and the casing contains two compartments 4 each containing separate circuit terminals and operative mechanism, as will be readily understood.

Having described my invention, what I claim, is 4 1. The combination with a suitable timecontrolled mechanical motor, a notched cam driven thereby, a pin coacting with said notched cam limiting the movements of said cam longitudinally of its shaft, a springtrigger urging said cam into engagement with said in, and a wing hingedly connected to the i i'ee end of said trigger efiected in reciprocative movements by the said longitudinal movements of the cam, of a switch closing element adapted to be supported in its open position by said wing in one of the extreme positions of the win and tripped to close when said wing is withdrawn.
