On the bottom end of the stem 22 is atsents an ordinary desk telephone instrument, nected thereto by a screw the purpose of which is to permit the assembling of the stem in the interior of the extension. In the lower end of the extension is formed a cavity 28, inthe same is inserted a metallic ring 29, insulated from the body prtion of the ex tension by fiber bushing 30, this ring acting as one of the contact points and it is provided at its under edge with a counter sunk formation acting as a seat for the conical shaped head 27 carried by the stem 22.

By this arrangement, when the hook is elevated the spring raises the head bringing the conical shaped head in contact with the ring '29 thereby closing the circuit and illuminating the bulb located above the dial.

The electrical connection is by meansrof a cord provided with plug inserted into an ordinary socket of the household, and the wiring between the contact and bulb is done in any manner well known to the trade.

The appliance is so constructed as to make it positively safe from shocks, as all manner of contacts are safely protected from communication by the hands.

Where the device is used on box telephones,

the bulb is positioned separately above the dial, and connected to the automatic contact by separate'wiring instead of being arranged on theattachment as hereinshown, but the method of making and breaking the circuit is the same. Some changes maybe made in the,con-
