Application filed March 18. 1912. Serial No. 684.369.-

Toall whom it may concern:

.Be it known that I. CARL H. BIssnLL, of Syracuse, in. the county of Onondaga and State of :New York, have invented a cer- Cluster Lamp- Socket, of-which the following is a specification.

This invention relates to incandescent electric lamp sockets and one of the objects thereof is the production of a cluster or plural lamp socketwwhich is particularly .Other objects will appear throughout the specification.

The invention consists in the combinations and constructions hereinafterset forth and. claimed.

In describing thlS invention reference. is had to the accompanying drawing in which like characters designate corresponding parts inallthe views.

Figure 1 is a plan of one form of my lamp a sectional view on line A A Fig. 1. v Figs. 3 and 4. are sectional views taken on the plane of line BeB, Fig. 2, the-connection for. a drop light being ShOWIlzlH Fig. 3 and for a switch in Fig.4. Figs. 5 and v6 are opposing face views ofithe bodyx and-cap 1 of the lamp socket.

This cluster-lamp socket comprises, gen- ,erally, a. hollow body openatone side,.a plurality.- of sockets associated with thebody, sideof the body lamp contact terminals in the sockets, conductors withimthe bodyconnecting like terminals of the sockets and .feed or plug terminals carriedbytthe cap and electrically connected respectivel .tothe conductors. In the illustratedmeml iodiment of my cluster socket,

.mea-ns..is provided by which another elec- .trical appliance may be connected in series with the conductors'between one of the feed orpl ug-terminals and said conductors if the switch, or may be com necteduin multiple-with the conductors, if the; appliance is a -.lamp.

9 and 10 are, respectively, the centrallandouter feedor plug terminals, the outer .terminal being mounted on .the periphery ofia central, projecting, cylindricalboss lllrising. from the-outer tace ofthe cap .4. .The central terminal 9--serves to hold,.th,e.-.c ap and bodyutogether and, .as here shown, comprises a screw, the.head.of which -is.located on the-end of the: boss 11 and theJlower threaded end of -.which Jturns into the threaded opening 12 of the yoke 8', the screw extending through, an enlarged opening 13 formed in the yoke] and axially alined with the screw threaded opening-12.

Ueshape. in,- gen eral outline, one branch of which is interposed between the terminal plate 22 on the inner face of the cap 4, and the other branch of which yieldingly contacts the upper face of the yoke 7 and conducts the current from the screw 1.) to the conductor 7.

25 is a removable link or clip electrically connecting the pair of screws 18, 19, said clip at one end extending under the head of the screw 18 and at its other end extending under the head of a screw 26 threading into the hollow screw 19.

As thus far described when the plug terminals are turned into a feed socket the current will pass'to or from the outer plug terminal 10 through one of the lugs 15, screw 18, link 25, screw 19 and conductor 24, yoke 7, terminals 5 through the lamps to the terminals 6, conductor 8 and central plug terminal 9.

27 and 28 are the opposite arms or wires of the branch circuit adapted to be connected in series between the plug terminals and the lamp terminals, or to be connected in multiple with the lamp terminals. When the arms 27, 28 of the circuit are connected in series with the lamp terminals, a snap switch is attached thereto for making and breaking the circuit to the lamp terminals, 5, 6, and one of the arms of such circuit as the arm 27 is connected to one of the binding devices of the pair of terminal members or screws 18, 19 as the binding device 23 of the screw 19, and the other arm 28 of the branch circuit may either be connected to the other binding device 21 or the screw 18 when the link 25 is removed, or may be connected to a binding device 29 projecting from the conductor 8. In the latter case the branch circuit is connected in multiple with the lamps and is designed to be connected with an incandescent drop lamp. The branch circuit extends outwardly through the opening 80 located between the sockets 3. In order to relieve the binding devices 21,, 28 and 29 of the weight of the wires 27, 28 and appliances, the wires are looped through holes 31 in the cap.

This lamp socket is particularly advantageous in that it consists of but few parts, which are easily assembled, and in that the parts are easily accessible, and further in that-either a drop lamp or a snap switch may be used in connection with the socket.
