switch for controlling the current which. is.

to be utilized by one or. more translating devices and also to the manner in which the switch is connected to the translating devices whereby two or more ofsaid devices may be connected in either series or parallel, or so that one device only may be utilized, or so that all the devices may be out out of the circuit at the will of the oplines.

it is obvious that any'other devices which depend upon the electric circuit for their source of energy may be utilized and it. is

also obvious that a greater number of translating devices than two may be utilized as long as they are assembled in two groups;

and Wherever in the claims two translating devices called for it is to be. understood that they are to cover arrangements in which there are tivo single translating de aft) vices, or two groups of translatingdevices or one single translatingdevice and a' group of translating devices.

The two translating devices are designated by A and B and these are connected in a manner to be hereinafter described to the tour-way switch C. The switch C has the insulating base D upon which are. secured-tho four stationary contacts a, b, c' and d, which may be referred to as contacts one, two, three and four, also carried by the base is a movable member, the turning plug E. --lhis turning plug carries three insu latecl metallic segments or bridges 8, s 8 which may be referred to as bridges one, two and three, which act ,as contact connect ing members or bridges, any one of which .will electrically connect any two contacts with which it is in engagement. The contacts have portions with which the ends of the segments or bridges engage when electrically connecting the contacts. All of the engaging portions of the contacts are arranged in two planes which are at difi'erent elevations. it will be noted tliaf contact ahas only one engaging portion a and that at the higher elevation; that contact I) has two engaging portions b' at thc'higher elevation and 0- at the lower; that contact a has only one engaging portion and that at the lower elevation; and that contact d has two engaging portions '(l at the higher elevation and (I at the lower elevation. It will also be noted that segments has ends arranged to engage only the contacts in the 100 lower In order to make clear the manner in 1 which the switch is connected to the lamp and the way that the segments or bridges connect the different contacts so that the desired results can be obtained reference is made to the diagrammatic views shown inlines indicated by F and F.

In Fig. 7 the plug E has been turned 90 from the off position so that it is in what is termed the high position and the current passes from F to engaging contacts of contact 0, over line 1 through translating device B, over line 2, 3, 4; to the engaging part d of contact d, over segment or bridge 8 and contact engaging portion a of contact a, to line F. The current which passes to engaging portion a divides at this point and part'passes over a segment or bridge 8 to engaging portion b of contact Z), from thence over line 6, 9, through translating device A and from thence over the same route'which the current over line 2 from B passes in transit to F, which route is line 1%,4, engaging portion d of contact 03, segment 8, engaging portion a of contact a to line F. It will be seen that this causes both A and B to receive 'the full strength of the current and that these de vices are connected in parallel. By turning the plug 180 from off-position we have the connections according to Fig. 8 which corresponds to the MDM position of the switch Which is the position when only one translating device is to be used. The current in this case comes from F, passes over engaging portion 0 of contact a, segment- .9 engaging portion (Z of contact (i, over line 5, 3 and 8 to translating device A and from thence over line 9 and 7 engaging portion b "of contact Z) se ment a en a ing I a a: V1 b a c portion a of contact a to lme 1* By turning the plug 270 from ofl? position We have the condition according to Fig. 8 which corresponds to the low position of the switch. In this position the translating devices are in series the current from F passes through engaging portions 0 of contact 0, to line 1, through translating device B, over line 2, 8, through translating device A, over line 9, G, to the engaging portion if of contact '1), over segnjicnt 3 through engaging-portion a of Contact a to line F.

Several of the claims include reference characters therein but it i s to be understood that sjuchreference characters "do not limit the subject matter thereof to the exact construction referred to and shown and described in the specification.

It is obvious that various modifications may be made without departing from the spirit and scope of my invention.
