There was no switch at the basement door and it was difficult to find the droplight in the dark. Instead of going to the expense of placing A switch, the contrivance illustrated and described was rigged up and proved equal to the requirements.
A 7/8-in. piece of wood was cut about 6 in. long by 2 in. wide and a recess made at one end for the socket, as shown. A 1/8-in. hole was drilled in the center, about 2 in. from one end, and another, large enough to receive the projection from a pull socket, about 2 in. from the other end, or the end to be used as the bottom of the block. A clamp made of spring brass, as shown, was screwed securely to the board, to clamp the socket firmly. A wire was passed through the small hole and stretched across the room from the door at a height to bring the light about 6 ft. from the floor. Then the socket was clamped to the strip with the chain passed through the hole cut for it. The cord attached to the chain was run to the door casing, passed through a screweye and weighted with a nut or some light object, to keep it taut. To light the lamp or put it out only a pull on the string was necessary.
The light can be slid along on the wire from one end of the room to the
