10 Claims. (Cl. lith -97!) The present invention relates to control devices and in particular to a variable or pluralcircuit device used in combination with a control switch, such as an electrolier and its wall switch.

One object of the invention is to provide for both remote and local control of the device and especially of sub-circuits in the device, such as the outlet circuits of an electrolier.

A particular object of the invention is to provide for such controls of the plural. circuits on a two-wire system, such as that commonly used in wiring electroliers.

A more special object is to provide for the remote or local control of an actuating member.

The nature of the invention as well as other objects and advantages of the same will be clearly understood from the following description of the devices shown in the accompanying drawing in which Fig. 1 represents an electrolier having a plurality of outlet circuits with two wires leading to the electrolier, one of them including at a re- Silt mote location the wall switch.

Fig. 2 represents a plural circuit electrolier having three wires leading thereto, commonly known as a two-circuit electrolier, with two switches. for the circuits, power to one switch being under the control of the other switch.

Fig. 3 is a modmed relation oi the two-circuit electrolier wall switches with each switch independent of the other.

In Fig. l a source of power 10 has one side connected by wire Iii directly to an electroiier. 'lhe other side 12 passes through a remote control switch 13 as in a wall. The remainder oi the figure is represented as the complete electroher and it contains a distributor for a plurality of outlet circuits and means to actuate the dis-.- trilcutor by power changes in the cinauit ll-i2 leading to the electrolier.

in the present instance the distributor comprises a rotary contact device illustrated diagrammatically by a disk or drum 14 arranged to close various circuit switches a, b,c, d, and e which control lamp outlets A, B, C, D and E between the line wires 11 and 12. One half of the disk or drum as a cam-like structure 15 particularly designated in order to indicate that all of said lamp switches may be open at the same time by arranging them semicircularly about the drum or disk in an inoperable relation to the dead half of the disk or drum.

Motive power for the switch actuator 14 is supplied by some sort of impulse motor, that is,

one which gives an impulse whenever there is a particular sort of power change in the circuit. In the present instance the power change relied upon is the opening and the closing of a local circuit, that is, one within the electrolier in association with the motive device.

An electromagnet 16 is connected across the line 1112 through a resistance in the form.- of a lampl? in one of the electrolier outlets, and through a local control switch 18, which is of a type normally closed or automatically closing. An armature 19 carried on an arm 20 pivoted at 21 is normally held withdrawn from the electromagnet by a spring 22. The arm carries a pawl 23 which actuates a ratchet wheel 24 step by step. The ratchet wheel turns the disk or drum by a suitable connection such as a common shaft 25.

By repeated operation of either switch 13 or 18 the switch actuator can be moved to change Z5 the number oi lamps that are lighted from a single one to a maximum in succession or in any combination in which the switches are actuated. Actuation by opening switch 13 will cause all the lights to flicker, but actuation from the 86* I local switch 13 will cause only the light 17 to flicker, and when this light used herein as a resistance is dispensed with or the resistance is otherwise provided for, no flickering will occur. The light 17 is desirably used both as a. lamp and as resistance for the reason that it serves as signal that current flows through the impulse motor.

in Fig. 2 two-circuits are provided from the remote control station, one being used as a so motor circuit and the other as a lamp circuit. A power source 30 is connected directly to the electrolier to provide a common return 31. An-

.other line 32 passes through. a switch 33 and then splits into two branches, one of which is a wire 34 for the light circuit and the other a wire 35 for the motor circuit containing also a con trol switch so.

in the electrolier there is a suitable motor, which may be such as that described for Fig. 1, but which is preferably of the continuously operating type as distinguished-from the impulse type. Such a motor is designated at 37. As this type is usually of a high speed character, I have illustrated speed reduction gearing between the motor and a switch actuating element 38. The gearing comprises a large gear 39 turned by a worm 40 on a motor shaft 41. Lamp circuits F, G, H, I, J and K with suitable switches are related 'to the actuator in any desirable manner. A local motor control switch 42 is connected across the two lines 34 and 35 so that the lights may be changed from the electrolier itself. By this arrangement all lights may be extinguished or lighted from either station independently.

In Fig. 3 a modified circuit is shown for controlling the electrolier. There are illustrated a source 45, two teed wires 46 and 47, the latter forming two branches which are a motor circuit 48 and alight circuit 49 with the respective switches 50 and 51.

It is to be notedparticularly that in the device of Fig. 1 there are sixteen teeth on the ratchet wheel and that at each opening of the motor circuit the wheel is advanced one-sixteenth oi a revolution, and that this angular advance corresponds with the angular arrangement of the lamp switches about the actuator. Thus, when lighting or extinguishing of the lamps takes place, one operation of the impulse motor will operate on one light, and successive operations of the impulse motor will successively operate on the series of lights.

The present invention may be embodied in a unitary device as a motor-operated distributor for insertion into electroliers already installed, in which case the wall switch'would be no part of the added combination. It is to be understood that various changes may be made, such for example, as the substitution of a reciprocable ratchet member or actuator, without departing from the present invention as expressed in the appended claims. It is also to be understood that the invention is not limited to use in electroiiers and that devices other than lamps may be operated by the device of the present invention.
