ELEGTIRIC-SWITCE-TMING .kfi AT'US.

To all iliom t mag/concern.'

Be ity known thaty l, ALBERT Error-inn nomia, ol' indianapolis, county ot Marion, and State of indiana, have invented a certain useful Electric-Switchffiming Apparatus; and .l do hereby declare tha-t the `Eollowing is a full,clear, and exact description thereof, reference being had to the accompanying drawings.

This invention was made particularly for the purpose of opening electric light-ing ein cuits in stores and the like and closing the circuits at certain hours in the day or night, and aside from the novel switch controlling means, la .further feature of the invention is the provision of an eighhday clock arranged in connection with the remainder oie, the mechanism so/that said clock will open and close the switch automatically for eight days without. any attention on the part of 'any person. Thus the lights in a store or store window can by such clock arrangement be turned on, say at (3:00 p. m. each day and turned oil' at l1 0G p. ni., and this will occur on Sundays, holidays and all other times without any presence or attent-ion of any person. Hence, as compared with prior devices which had to be turned oil' and on each day by an individual, there great saving of money well greater regularity in the lighting ot' a store or store window.

The nature of the invention will loe understood lfrom the accompanying drawings and the following description and claims.

ln the drawings Figure 1 is a front. elevation of the apparatus with the door of the switch box removed, and showing the position of the parts when the switch and elec; trie lighting circuit are` open. Fig. 2 is the saine/showing the position of the parts when the switch andy lighting eircuitare closed. Fig. 3 is an elevation of `the magnets and associated parts viewed ifrom the line 3-3 oi 1.

| an elevation of a portion of the gearing in the clock for controlling the 12-hour 'and 24- hour hands. Fig. 9 is a section on the line 9-9 of Fig. S. Fig. 10 is a plan 1ieW of one of the switch arms on the clock. F ig. 11

is a section on the line 11-11 of Fig. 10.V

12 is a diagram of the wiring of the circuits for controlling the main switch.

The main or lighting circuit includes the wires 10 and 11. and the switch l2. This circuit is controlled by the clock 13 through the intervention'ot' the switch actuating denice 14, so that when the Switch is in the position shown in Fig. 1, the lighting circuit is open and maintained in open condition. and when the parts are in the position shown in Fig. 2, 'the light-ing lcircuit is i closed. To regulate this switch an eight-day clock is used with only the following gchanges: it. 24l-hour hand 15 is provided so ftliat at one time during each 24 hours its outer end will engage the outwardly projecti ing pin 1li on the switch closing bar 17 and also later will engage thecorresponding pin .1G on the outer end of the switch opening 1 bar 153.A

The QLl-hour hand 15, therefore, comes in engagement once in every 24 hours L with cach of the bars 17 and 18 in the order named. The gearing in 'the clock is :nodilie'd, as shown in Figs. 8 and 9, for driving the Ql-ho-ur hand 15. This ar angenr'ent is combined with the means for driving the 12- hour hand 20, but geared so that the Q4l-hour 'hand 15 will move only half as fas-t as the .is secured on the shaft lil-hour hand 20.

The Q-lioui' hand 15 is secured on a shaft 23, which is mounted about the 12-hour hand shaft 22, and on the latter a gear 24 is secured which meshes with a large gear 25, so that the latter will be driven. ny the 12- hoiir hand gear at exactly half the-speed of the oear Q4. A gear Q6 is secured on a shafti to which a car 25 is secured and meshes with the Eil-hour hand gear 2S, which 22. Since the wheels 25 and ZS are of the saine diameter, the shaft. .32 will be driven only at. halt the speed of the shaft 23. A

The hars 17 and IS are made alike but both so as lo be lengthelied or shortened. This is accomplished. by making each of said bars out ot two overlappinginter-engaging strips, but For convcnieiuo cach pail' of strips is herein called a bar. One end of the bar 1T is tulcrunicd to a. pin 3U. and one nin flir-l the clock.l ich har has a pin in one ef the series in vthe diei oi' the "i the center therec' the hai-s .y articular time 2 the circuit clesio close tl e circuit opening hair 1&5 circuit at about 11:00

A ratchet Wheel T9 is secured on the shalt 75 and rese/iis the haci: Wall ci the cabinet. rEhe needle bar el., is loiifger'tlian the hars (30 and (i2, and the licei er said har (51 has :i spring (36 ceniicctcd with it, ivhici rims down te the nin "5T fastened ie the casingA :ine arranged so as to lend te throw the switch to its closingy positieii. 'The other end of the lever (il pi :jects beyond the cross bei.' l2 Ol the siii'l'ch frame for .some distance and it has a r'cli'ci (3S on it. 'lhe bars (SO and (32l of the switch engage the terminals .nd 7l. secured in said plate lr6-li and with. which the wires l() and il of the main er lighting circuit lire resivicctiifely ceiiiiected.

The main switch lever (5l is connected with the lever '-15 ot (he clock circuits by a link 72, sc that the inaiii switch will centrel and Operate thc switch for the clock circuits hv nmviiigg`l the latter against. ene contact when the iiifiiii switch closed, and against the other contact when the iiiaiii switch is opened, as shown iii l and 2.

The niain switch. is operated hy :i threearni switch actua/ting device Us. lt

lcosely mounted oii i shaft. T5S which is mounted iii any suitable manner .in the cahinet and which curi-ies a'pin wheel TG, and a operates on said pin wheel and.

power is transmitted from said shaft through said ratchet. wheel te the arms 14 hy a. pawl S0 iiiountedoii the arms 14 with its ends pressed into engagement with the ratchet Wheel hy a spring Si. also mounted on the arms lll. After the Weight 78 has 1 run down, in the course et eight clays, it is -i'veund up by merel;7 pullingdown on the free end et the chain. The arms 14 `are iiiciiiited so that their ends will engage the `roller 5S on the main switch lever 61 and more it from the closingg-- position shown in Fig'. 2 te the open position shown iii l.

The forward movement of the switch actuai'ing` arm 14 is i'irst-Vstc'pped by the shoulder en the stop lever 8G iilcriiined it one `end te the cahinet it 87. cie said lever 8G is held by strip lever 88 The upper end fulcriimed at 92 at its ether eiid i o the frame n ate S9, which is secured to the cabinet,

litigi'. The stop lever 86 has also another shenlder SO adapted to caytch 'the end of zin arm 14;. and on that occasion the upper end elf the lever 86 is stopped sind held hy trip lever lil tulcriinied to the frame Sil'hy a Inin The trip levers 88 and 91 are parallel. with each other and similarly inciiiited en the 'trame plate 89 end lie on each side of a projection 9S which separates them. They are lifted or actuated hy the armatures Qdiand 95 which lie respectively Iunder the cores of the magnets 3G and lll,

find are fiilcriimed at one end to the frame plate 89, and when either of sind armatures is lifted, e pin 9G on the turned down ends nooners of the armatures engages the undersides of the trip levers 88 and 91, respectively, and lifts them out of holding engagement with @therend of the lever 86, which is wide enough 5 to be engaged by either trip lever.

toward the lever 86 than the corresponding" shoulder on theother trip lever. Hence the shoulder 100 on the trip lever 88 will hold the lever 86 so that its shoulder 85 will engage and stop the end of the arm 14, as shown by dotted lines in Fig. il, but when the trip lever 88 is lifted, thenthe arm 14 can move farther until it engages the shoulder 90 on the lever 86, and at that time the upper end of the lever 86 will be held by the shoulder 100 on the trip lever 91, which is slightly fart-her back than the shoulder 100 on the lever 88, as appears by full lines in Fig. 4A. Therefore, the sto-p lever 86 stops the arms 14 twice, once in order to hold the main switch in open position, as shown in Fig. 1, and which is brought about by the clock circuit being closed by the bar 18, thus energizing the magnet 41 and lifting the trip lever 81 from the position shown in Fie'. '2, whereupon the weight .78 will move the arms 14 and the main switch to the position shown in Fig. 1. It will stay there until Ithe time for the main circuit to be closed and when the 2L1-hour hand reaches the bar 17, the other clock circuit will be closed and the magnet 36 energized, which will lift the lever 91 and let the arms 14e pass from the position shown in Fig. 1 to the position shown in Fig. Q, and then the main switch will close and stay closed until the d-hour hand reaches the bar 18.

The spring 195 secured at one end to the cabinet pushes. with its other" end against the lever SGand tends to force it toward the 'arms 14. "The'pins 96 hold the trip levers 88V and 91 in such position that the backward movement of the upper end of the lever 86 will always cause' it to pass under the projecting ends of the trip leversand against the most forward shoulder 100 whichl;` on the trip 91. As the arms 1/1 turnthey engage a spring 97 mounted in connection with the lever 86 and pass beyond its free end against the shoulder 85, and then the free end of the spring 97 snaps behind the :1r-rn 14 which is'notched at 98 and prevents any return movement of the arrnslt during rewinding of the weight 78.

It is not necessary that the invention should be limited to any particular means for 'actuating the arms 14, although the weight and chain are convenient, nor to the particular construction of the other parts so long as they perform the functions in the manner indicated. The main switchcom trois the switch 15 so that it puts the properclocl( circuit in condition to be closed by the 2li-hour hand when the time cornes; s

The bars 1'? and 18 on the clock can be shifted to any' desired space or part so that the main or lighting circuit will be opened Jfor the desired period of time.; This period of tiniemay be any fraction o1 24 hours.

Provision is made for closing the `main or lighting circuit independently or' the clock. This is by means of the hand-operated switch construction 110, see Fig. 2,'secured to the side of the casing, which is connected by the wire 11?. with the wire 35 and is also connected with the wires 110 and. 140, and wires 116 and 117 lead from it to the bat tery through the wire 52. The details of this switch construction are indicated in diagram in Fig. 12. r1`here is a magnet 11e connecting the Wires 410 and 140, and, there- `tore, constantlgY in the circuit controlled by the cloclr arm 18. This magnet has an armature switch 111 tulcrumed at 118 and adapted when released from the on-lever 180 to drop down into engagement with the contact 119 which is connected by the wire 112 with the wire 35, and therefore, the cir cuit controlled by the clock arm 17. The on switch lever 128 is fulcrunied at 121 and a hoolr 122 on the lower end adapted to engage the armature switch 11,1 and hold it out or'. engagement with its Contact 119, and this locking position 01"' the lever 12() is maintained by the spring 123. Therefore, when said armature lever 111 is down into en*V gagement with contact 119, current will pass from the battery 51, wires 52 and 11?, armature lever 111, contact 119, wires 112 and 85, to magnet 36. There is also an o1-- switch 115 which is adapted to engage contact 113 connected with wire l10, and the switch 115 is connected with the wire 52 by the wire 116. Therefore, whenfthe oli-switch 115 is operated, current will pass from battery 51 through wires 52 and 116, switch 115, contact 11B, magnet 11e, `wire 111 to the magnet 111, etc., and that will not only operate the 'means controlled hf; the switch closing circuit and in which they magnet 4l is situated, but will also energize the magnet 114i and cause4 it to litt-he armature switch out of engagement with its contact 119 as to be caught hy the notch 122 on the on switch lever 128. That will open the circuit controlled by the oirswitch lever and/Still turn the parts to their normal posit;` n. This hand-operated switch n1echanism,ho'.v ever, is such that it does not interfere with the cloclt in controlling the clock circuits.

Thus, il? the main or lighting circuit hhs been closed hv' pushing the on-loutton of the hand-operated switch, the clock at 11:0@ p. in; will put the lights out, for as soon as the circuit controlled ny the clock arm.18 is closed, it. will energize the magnet 1111- and c imm 1 The Clock 21 :iii pm adapte i 2.
