The light bracket shown is both ornamental and useful and can be swung from one side of the room to the other in an instant, a feature that is of great value in a dimly lighted kitchen. It can be made of either brass or soft iron, but, for the sake of convenience, the description will be for one made of brass.
Procure four pieces of brass, 1 in. wide, 1/8in. thick and 7 in. long, and bend them to the shape shown at A. These are to form the ceiling bracket. A 3/16-in. hole is drilled in the end of each piece to be against the ceiling. The other end is bent slightly concave and soldered to a brass collar, B, which is threaded on the inside. This collar must be of such a size that it will screw on the end of a brass pipe, C, 1 in. in outside diameter. The length of this pipe should be 18 or 20 inches.
The base D of the bracket is made of a brass bar, 1/8 in. thick, 1/2in. wide and 45 in. long, a scroll being turned on 6 in. of its length at the globe end, and 3 in. of the other end turned up at right angles and soldered to a ring made of 1/16-in. brass that acts as a bearing around the pipe.
The upper brace E is made of 1/16-in. brass, the same width as the base piece and about 48 in. in length. Each end is turned into a scroll and then riveted or soldered to the base D and to the upper brass ring. The space between the base D, the brace E, and the pipe C is filled with any style of scroll or other brace that may suit the taste of the maker, but the base D must be at right angles to the pipe C before the scroll is fastened in place.

A cap, F, is screwed to the lower end of the pipe, to keep the bracket in place. Ordinary flexible light cord is used to connect to the light which is swung to the scroll end of the base. - Contributed by F. L. Matter, Portland, Oregon.
