AUTOMATIC LIGHT-SWITCH.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application tiled February 23, 1907. Serial No. 358,839-

To all whom it may concern:

The contact members l1 and t2 are connected to the lie it known that l, Ilnxnv Enwanns Kixo. a citi- I terminals of a lighting circuit lt including a battery Zen of the lfnitcd States. residing at liunkie. in the parish of Avo velles and State ot' Louisiana. ha e iuvented a new and usel'ul Automatic Lightmwitcn, which the following is a specification.

This invention relates to automatic alarms and more particularly to an electric switch especially designed tor use in connection with an alarm clock tor automatically closing a lighting circuit at prea etermined intervals.

The object ot the invention is to provide a switch including 'a pair ot contact; members one ot which is arranged in the path of movement of the hammer ot an alarm clock or similar device so that when the alarm sounded the hammer will move the adjacent contact to circuit closing position and thus light the lamps.

A still further object ot the invent ion to generally I improve this class ot' devices so as to increase their utility. durabilit and etliciencv.

With these and other objects in view the invention consists in the construction and novel combinai ion and arrangement, of parts hereinatter tully described. and illustrated in the accompanving drawings, it being understood that various hanges in term. proportions and minor details ot' construct ion may be resorted to within the scope of the appendet'l claims.

in the accompanying drawings forming a part of this speciticatimt: Figure l a front elevation of an electric switch constructed in accordanc with my invention showing the movable contact, in position to be engaged by the hammer of an alarm clock. a rear elevation ot the casing or housing showing the relative position of the contact members. Fig. I} is a longitudinal sectional view taken on the line S- 3 of Fig. 2. Fig. t is a transverse sectional view taken on the line 4-4 of Fig. 2.

Similar numerals of reference indicate corresponding parts in all ol the figures ot the drawings.

The device comprises a casing or housing 5 designed [or attachment to a wall or other suitable support and provided with vertically disposed lugs 6 having perforations tormed therein for the reception of screws or similar tastcning devices 7 whereby the casing may be conveniently supported on the wall.

The casing 5 is provided with a pivoted cover or closure 8 having a spring catch or similar fastening dcvice 9 secured thereto and adapted to engage the top l of the casing for locking the cover in closed position. The opposite end walls of the casing are provided with alined openings in which are seated bearing collars or .1

sleeves 10 adapted to receive a pair of contact mem bers 1] and 12, there being bushings l3 formed of rub- 115 and one or more incamlescent, lamps to. tact member it is relatively stationary while the member .12 is mounted tor longitudinal movement within the casing or housing and is provided with a terminal head 17 which extends in the path ot movement of the vibrating hammer 18 of an ordinary alarm clock, indicated at it).

The head i7 is cccentrieal1y mounted on the adjacent end ot' the movable contact, l2 and is preferably provided wlili a. disk 20 tormtd oi rubber or other suitable yiclt'lable material adapted to receive the impact of the hammer 1S.

Secured to the inner wall of the cover or closure 8 is a strip ot metal 3t having a laterally extending tlangc 22 dctining a pocket tor the reception ot an insulating block 225, the latter being prt-t'erably termed of glass or other suitable material and having a convex tact adapted to bear against the curved or deflected end j) of the stationary contact member l l.

The tree or inner end or" the movable contact member 12 is provided with a laterally extending lip 2t; adapted to engage the defl cted end 25 of the stationarv member it and thereby close the lighting circuit win-n the contact 12 is moved longitudinally by engagement with the hammer 18 ot' the alarm clock.

in operation the clock, is set to sound the alarm at any pre-determincd period and the movable contact l2 arranged in the path of movement of the hammer IS. as best shown in Fig. :1 of the drawing When the alarm is sounded the hammer l8 will strike the head l7 ot' the movable contact and t'orce the latt r longitudinall in engagement with. the llattened end ot' the stationary contact l'l tints autolmiticallv closing the circuit and lighting the lamp or lamps. in order to extinguish the lamps it is merely necessary to exert a longitudinal pull on the head or linger piece 17 when the contacts will be separated and the lighting circuit broken. i

Attention is called to the tact that by having the instilatiug block 43 t'ormed with a convex lace and the flattened end of the stationary contact Ill bent to conform to the contour ol the lace ot' the block, the contact 12 when moved to circuit closing position will ma kc a wipe contact with the member it and thus insure a good electrical connection between the two. it will also be observed that when the detlccted endof the movable contact 12 engages the inclined end ol' the stationary contact the end 20 ot the movable contact will be lore-ed outwardly thus exerting a sprin action on the stationary contact and serving as an additional means l'or holding both contacts in circuit closing position. 3y having the insulating block 23 arranged within the pocket and the latter secured to the pivoted wall or closure-8 when said block becomes broken or otherwise injured from rough usage or from any other cause-the same may be he coni readily detached by moving the door or closure 8 to open position and removing the block through the open end of the pocket, as will be readily understood.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary.

Having thus described the invention What is claimed is:

1. An electrical switch including co-acting contacts one of which is provided with a terminal head having a cush ioning member secured thereto, an energized circuit the terminals of which are secured to the contacts, an insulating block bearing against and forming a support for the adjacent end of one of the contacts, and an alarm clock having a vibrating hammer adapted to engage a head of the adjacent contact for moving the latter to circuit closing position.

2. An electrical switch including a casing, relatively stationary and movable contacts extending through the walls of the casing, one of said contacts being provided with a terminal head, an insulating block disposed within the casing and engaging one of said contacts, an energized circuit connected with the contacts, and an alarm clock the hammer of which is adapted to engage the head of the adjacent contact for moving the latter to circuit closing position.
