Such an ar- 2. ontsaidmemberflvisa contactportioni t2 with rangement is bulky and inconvenient, and is the which'thejspring'at itslfree'endrhascontactionzocsource of trouble and annoyance each time a lamp casion, said portion I 2 being connected intcathm is to be replaced. Again, the commonly used lamp primary circuit by a wire l3. Again, a wire I4 is connected to and between the receptacle 4 and one side of the secondary coil, not shown, of the transformer, while a wire 15 connects the other side of the latter with the receptacle 4'. Through the connections described, or part of them, it is evident, of course, that the primary circuit can be opened or closed by the spring 9.

Attention is now drawn to the fact that, as shown, the receptacles 4, 4 due to the coiledwire form thereof are expansible axially by the insertion of the lamp 5. In Figure 3 it is observed that when not under stress the receptacle 4 is a compact cone, the convolutions thereof substantially abutting each other, and that the spring 9 of the circuit breaker is normally distant from the contact portion I2, the primary circuit, therefore, being open. However, when the lamp 5 is seated in said receptacles 4, i the coils of both these members are expanded as shown in Figure '7 from the fact that the distance between the apices of the cones when the latter are unsprung is less than the length of the said lamp. In mounting the lamp one end thereof is first nested in the receptacle 4', sufficient pressure being exerted to permit the other end to pass to the center of the receptacle 4 and brought into the line therewith whereupon the receptacle 4' which is under stress will push the end at said receptacle 4 of the lamp into that receptacle for seating, and the apex of the cone will be moved toward and against the strip l0, and by the latter spring 9 is forced into intimate contact with the conducting portion I2, closing the previously open circuit.

It is to be understood, of course, that the receptacles 4, 4 may be identical in respect to reaction under stress, and that they are so spaced that the receptacle 4 and the pressure exerted by the receptacle 4 will be sufficient to bring about circuit closing.

While the particular structure of the receptacles described answer admirably the purpose intended it is possible to use some other form yielding like results. Thus it is not the intention to be confined necessarily to What has'been shown and described in respect thereto. The same may be said in respect to other parts herein described.

In placing the circuit breaker 8, 9 in the primary circuit all current flow through the secondary coil of the transformer, 01- through any other electric system used, as earlier noted herein, is avoided naturally, so that no chance harm can be done to the latter by current flow were the circuit breaker otherwise connected during an interval when the lamp may not be in place.

I'claim:

1. Means for mounting a lamp and for closing a circuit therethrough, including in its construction, and in combination with the primary and secondary coils of a transformer, a normally open circuit breaker connected in circuit with the primary coil, a receptacle erected adjacent the circuitbreaker normally free thereof, part of said receptacle being yieldably extensible toward said circuit breaker adapted to abut upon the same to close the primary circuit therethrough by a lamp inserted at one end into said receptacle, and means to maintain elastic pressure endwise uponthe lamp in the direction of said circuit breaker to maintain closed relation thereof, said receptacle and said means being connected with the secondary coil, closing the circuit through said lamp.

2. Means for mounting a lamp and for closing a circuit therethrough, including in its construction, and in combination with the primary and secondary coils of a transformer, a normally open circuit breaker connected in circuit with the said primary coil, a receptacle erected adjacent the circuit breaker normally free of the same, part of said receptacle being yieldingly extensible toward said circuit breaker and to abut upon the same to close the circuit therethrough by introduction of one end of a lamp into said receptacle, and a second receptacle at the other end of the lamp, the same adapted to exert a yielding pressure on said lamp in the direction of said circuit breaker to maintain a closed primary circuit, both receptacles being in circuit with said secondary coil'through said lamp.

3. Means for mounting a lamp and for closing a circuit there-through, including in its construction, and in combination with the primary and secondary coils of a transformer, a normally open circuit breaker connected in circuit with the P mary coil, a receptacle erected adjacent the circuit breaker normally free thereof, said receptaole consisting of a helix of spring wire, part of said receptacle being yieldably extensible toward said circuit breaker adapted to abut upon the same to close the primary circuit therethrough by a lamp inserted at one end into said receptacle, and means to maintain elastic pressure endwise upon the lamp in the direction of said circuit breaker to maintain closed relation thereof, said receptacle and said means being connected with the secondary coil, closing the circuit through said lamp.

i. Means for mounting a lamp and for closing a circuit therethrough, including in its construction, and in combination with the primary and secondary coils of a transformer, a normally open circuit breaker connected in circuit with the said primary coil, a receptacle erected adjacent the circuit breaker normally free of the same, said receptacle consisting of a coned helix of spring wire, part of said receptacle being yieldingly extensible toward said circuit breaker and to abut upon the same to close the circuit therethrough by introduction of one end of a lamp into said receptacle, and a second receptacle at the other end of the lamp, the same adapted to exert a yielding pressure on said lamp in the direction of said circuit breaker to maintain a closed primary circuit, both receptacles being in circuit with said secondary coil through said lamp.
