lo (gli whom it may concern.;

Re it. known that I. Sinontmn CHIGER. a euhject of the Emperor of Austria-Hi'ingfary, residing at 65 Kurfrstendamm, Berlin, (lrer-- many, merchant@ have invented new and' use- `t'ul linprovements inEleetrie Time-Switches; ot which the following .is a specification.

The invention. relates to electrical time -uitehea which are applicable to clocks t'or timing the operation'ot alarma or for time contro-lling` other operations. rIhe'said time switch is adaptedto he operated hy the ordinary clock hande, and haa'tor its principal object.' to enabley any ordinary clock to he converted into an alarm clock.

.Wemding to Vthe, invention Ia movable lwitch contact piece is arranged to he moved hy a. cloek'haud in -a closed curved path aroundthe .axis otrotation ot such hand. luto this path fixed contante may he ineerted` at any desired place which contacta on being' engaged by the'movahle Switch contacty close the electric circuit ot an alarm loell or other device. 7 f

The improved Switch may readily he. oontructed' in 'such a-mauner that' the distances or periods between the lpoints at which the alarm' is to he given may he altered as de-l 'aired loi,v 'verysiinple manipulations.v The apparatus may. for instant-e, he arranged in. auch manner to eauae a-nfala'rm to he `given at a 'certain hour of the day and at the `Same hour during' the' night-or it `may he set for soundingzin alarm at acertain hour' ot the, day only or otthe nig'ht *only` alao it may be adjusted ao as to produce alarms at ditferent times duringr the ila-y and during the night. Tho improved device alo enables the time -atYhiCh an alarm ia to be given tohe set Several daye in advance.

ln the aecmnpanying` drawings a construe` tional t'orm ot the improved device ia illustrated by way of example. Figure l is a tront elevation partly in seetion. Fig. .2 ia crois Section on theline A in Fig. 1.

The device is preferably placed in frontof the dial a of the lclock and comprises4 an annular or (liek-Shaped frame r! arranged eoncentrically with the arhor ot the clock hands and f'. et which 7) is the hour hand while o is the minute hand. lu the Jframe flia slid- Patented July f3, 1951.2. 1911'. serial No. 621.595.

ably mounted the niovalole switch eont'aet o ivhich is actuated hy the hour hand In,

The 'Contact e may as Shown. he' formed ot bent Wire with an outer bent tinger portion adapted to bear uponthe tace ot the. insula- .tion annulus (Z, an intermediate portion adapted to move in the mouth ot a groove f. an end vportion adapted to move Within the inner recessed portion f/ 7 1I ot theI groove. and an .outstanding fork tor engaging the hour hand 2).- The contact piece is thus Lluioed in the' cam Agroove formed in the inaulation Vannulus d1 xed on the disk f7 .which `groove so p' .controls themoveinent'of the eoutaetvpieee.

Thetwo Walla of the groovethus consiat ot' "insulating material, one ot the walls heingf provided with a reeeea g into which the con- 'tae't piece lengage and the `oppoaite wall heing provided with a reeeas la. in which lietay a conductor 2' each ot which iQ adapted to he y rubbed by the Switch Contact e. the conductor z' as shown. may conveniently he a flange or rib on the disk fl. rl'he conductor ia connected to one terminal ottne circuit hy toggle links an. These linka are shown connected to a` lug or arm m1 on tliefliak a7.. The terminal is mounted on a plate a ieh may be fixed`near to' the periphery ot the dial plate by a clamping device or any other' suitable means.. The other' terminal n of the' circuit which is also mounted on the plate n is-conneoted by toggle links yo with a projection f] of a metal ringI r fixed to the `traine,V

(I but insulated troni t'he conductor as. .eeen Clearly in Fig. 2. y

Thel metal llring 1" is provided on its oir-- eumference': with projections in whieh are formed slots I nt'ront ot these projections are arranged Contact-pieces or rods nl and il:

which are received in Suitable more or less ra dial hole@ in the1 insulating material. The, Section td the left hand side ot Fig. 1 iataken in'a plane parallel With-the plane ofthe dial ao as to display these holes. The outer end ot each Contact rod or pin if or 7/2 is bent to torni a hoo-k which. when a rod it fully incerted may paez= into the appropriate Slot hetu'een the two parts ot the projeetion s the' 'hooked end: heine` canied toy toueh auch parte and thus makingl eontaet/wltl'i the metal ring' r.: lVheu auch a contact rod ig pulieslnouie. inthis wav the inner end thereof pi'of into `the recess fj of the guide groove f so as to l'ie inthe path of the movable switch con'- ta'ct e driven by the clock hand. The path in which the contact e is moved by the clock hand is generally closed on itself' and' may in itssimplest form be constituted by a circle.

It may however also .have the form of a.

therefore impossible for the contact e to peri form twice in succession a movement in the outer convolution or 1n the Inner convolution but it is constrained to move firstinthe one loop and then in the other. This is clearly to be'seen from-F ig. 1 for as the conjtact e comes around the inner loop toward six oclock it is given such a set as will direct it into the outer loop, and when it comes laround the outer loopt'oward the same point it is given such a set as will direct it back into the inner loop.

The outer convolution of the guide groove f may be traversed b v the contacte during the day, while the inner convolution may be traversed during the night, or vice versa. When the contact rods u1 and 'u2 are in their inoperativev position, that is to'say when they are pulled out of the grooves g, the electrical circuit of an alarm or other device 'cannot be closed. If however a contact rod u2 be pushed in Aso that its hooked end comes into the slot t of the corresponding projection s as seen at.nine oclock in Fig. 1 the inner end of the contact rbd projects sutiicientlv .into the groove 4g to engage with the movable switch contact e upon the-latter being' brought opposite the.co ntact piece u2 byV the movementI of the clock hand. As the contact e is constantly bearing upon the 'flange 2' it is lobvious that this engagement with the rod'u2 will electrically connect the disk (I and ring r so that the gap previously open between the` te1minals l and o .is now closed.

Any desired number of contacts u1 or u2 may be used. it is. essential that'those edntacts al which project intovthe inner convolution4 of the guide groove shall not pass throughA tliouter convolutionof the guide groove, Vor t least that they shall not lie in the; path of the movable contact e when the latter is traversiugthe)outer convolution of the guide groove. as ,otherwise these coitacts ulmwouldestablish lcontactwithfthemoyable 'tact .e moves, in the 'If both contacts u1 .larly at intervals of Contact e at intervals of l2 hours. On the other hand the contacts u? which are intended to establish contact;l with the movable contact piecewhen the latter moves in the outer convolution should not project into the inner convolution. From Fig. l it can easily be seen that the contacts u2 correspond with the outer` convolution while thecontact-s u1. correspond with :the inner convolution. The contacts u1 are 'in ade somewhat'thin-ner than contacts u2 so that theylie somewhat to the rear of the contacts u2 and are not 'toubhed by the movable piece e when the latter moves in the outer convolution. The contact between the mov'able switch contact e and the-contactslul'is therefore made only'when the coninner convolution. Owl-ng to therods u1 being thinner than t e .rods u it` is convenient to cause the thinner ends of the rods u1 to enter holes in little contact blocks a3 which latter lie in thepath ofthe Contact c whereas the rodsl Vu2 being thicker their-extremities actually lie themselves in the path of the contact c.

If it be assumed that the contacts u1: close the circuit at a certain time of the day the"- corresponding contacts u2 will if brought into operative position close the circuit .12 hours later and therefore during the night.` and u: of a pair are pushed home the alarm will be given regu,- 12 hours. If only one conta-ctof a pair Abe pushed home the alarm will be given at intervalsof. 24 hours.

The toggle links 7J and m are arranged in .a plane-behind theclock hands and serve forfacilitating the fixing of the device on clocks of various diameters.

It will be understood that when applyiilg the device to a clock of smaller diameter the. links will fold so as to contain a moreacute angle, while with a clock of large diameter the links will open so as to contain an obtuse angle and allow the'plate u to beI moved lfartl1caf-away from the center of the clock dial@ Further facility in fixing the device .to clocks of various shapes is afforded by making the outer ,pins c slidable in the tubular terminal sockets Z and 0, so that the plate n may be easilj7 adjusted inthe direc-v tion perpendicular to the plane of the disk .(Z, `Set screwsx serve to firmly securethe pins v in the lsockets'after the adjustment has taken place. The plate n. may of course be fixed to a'ny desired part of the peripheral portion of the dial plate or the clock casing. The terminals Z o are suitably connected in the .circuit containing the battery and the alarm bell but theseiconnectious are not shown as they are obvious to :tn vbod)y skilled in the art.

The frame d nla'y be made conveniently in tivropart'siso'as to enable the same to -be fixed behindgthe hands without necessitating the 130.

removal of the latter. 'The'frame (Z ma)v hifwjer be inserted into the dial plate., or may form .part of the same if desired.'
