To all whom it may concern: the other to put them all out and the other to Be it known that I, CHARLES E. SORIBNEE, a leave the individual lamps subject to control citizen of the United States, residing at Chiby the individual switches or keys of the difcago, in the county of Cook and State of Illiferent lamps.

But

Fig. 3 is a View of a chandevidual switches b. If, however, both of said 5 lier which may be provided with circuits as switches c d should be open then all the lamps shown in Fig. 2. Fig. t is a modification of a would necessarily be extinguished. Morethe switching device at the controlling station over, if both contacts 0 cl should be closed to adapted to assume three different positions, main B all the lamps a would be lighted be- 50 one position serving to light all the lamps, cause the individual switches b have each 10 only two positions; each must rest upon one contact or the other. Thus by means of the switching device and the circuits illustrated a very large number of lamps may be controlled at a single station; that is to say, all the lamps may be lighted or all may be extinguished, or each lamp may be left subject to the control of its individual user.

I have sometimes used only one lever of the switching device in connection with a chandelier, this arrangement sometimes being found most convenient when it is desired to light at once the whole chandelier or such of the lamps thereon as may not have been lighted by the use of the individual switches. This modification is illustrated in Figs. 2 and 3.

The mains A and B may be the same as shown in Fig. 1.

The lamps c c and c e are connected at one terminal with main A and at the other with an individual switchf, the individual switches being indicated atff and f f. These switches fhave each two normal positions each resting either upon one or upon the other of its pair of contacts. One of these contacts of each pair, in this instance the left, is permanently connected with main B; the other contact of each pair is connected with a switch g adapted to make and break connection with said main B. Now itis evident that when switch g is closed to main B the unlighted lamps as ff will be lighted. This arrangement in chandeliers is especially convenient since it is sometimes desirable to have only one lamp lighted for a time and afterward it may be desired to illuminate by lighting the remaining lamps.

As shown in Fig. 3 the switch g is preferably placed in some convenient position un-. der the chandelier; the individual switchesf may be placed at the different lamps and may be in the usual form of keys now used in connection with incandescent lamps.

It is evident that in place of separate levers c d as shown in Fig. 1 a single switch 7L may be used provided with two prongs with contacts suitably arranged. This switch 7L has three normal positions. \Vhen turned to the left the contact will be closed only to the main B while the contact (Z will be open. When in its upright or central position both contacts 0 (1 will be open to main B and when the switch is turned to the right both contacts c d will be closed to main B.

As shown in Fig. 5 the lamps are arranged in separate groups between the mains A and B.

By means of the switching device i it is evident that all the lamps of both groups may be positively controlled. \Vhen, however, only one of the circuits 2' 7c is connected with the main B the individual groups of lamps Z on will be subject to the control of the switches a 0 respectively. Thus my system may be extended as desired.

My invention admits of various other modifications which would readily suggest themselves to those skilled in the art and I therefore do not limit myself to the construction shown.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1. The combination with two mains of trans lating devices arranged in multiple are between them, said separate translating devices being provided each with an individual switch at one terminal adapted to be connected with either one of two branch circuits and a switching device included in said branch circuits adapted to open or close either or both of said branch circuits, whereby all the translating devices may be simultaneously brought into circuit or disconnected therefrom or left to be controlled by the individual switch thereof, substantially as and for the purpose specifled.
