ELECTRIC-LIGHT BRACKET.

To all whom it may concern: v

Be it known that we, ALBERT F. ANDER- SON and CHARLES W. Amvrs'rno vo, citizens of the United States, residing at Tacoma, in the county: of Pierce and State of Washington, have invented a new and useful Electric-Light Bracket, of which the following is a specification.

This invention relates tobrackets, for electric lights and has for its objects to provide an adjustable support for the light, by means of which the light can be placed in a and such that the light having been thus placed it wi: remain in said tain these and other objects by the devices, and arrangements illustrated in the accompanying drawing in which- Figure 1 is a side view showing the bracket extended horizontally from the wall; Fig. 2lslrows the same bracket folded and swung against the wall; Fig. 3 is a section showing the spring clamp; and Fig. 4 is a diagrammaticview showing the bracket in two extended positions to lllustrate the j stment thereof.

vertical axis, and its end on which the electric light is carried is adapted to occupy any position radially between the inner and outer limits thereof and any vertical position within a great area.

Referring now to 1 is secured to the wall or other support by The four screws 2 are arranged in pairs along a vertical line, each passing through the eyes formed in the ends' of suitable yoke pieces 3, said yoke pieces being raised from the surface of the plate 1 by suitable'washers 4. The yoke the eyes and may suitably be These yoke pieces which the brack't Around each yoke piece 3 a metal strip 5, is passed to form the hinge of the bracket. To one of these strips 5 is pivotally secured a bar 6, while a similar pair'of bars formed in their .ends made of heavy wire.

are each pivotally secured to the ends of two equal bars 9 which are pivotally joined in their centers, and which are in turn pivotally secured at their other ends to other similar bars 9,-all said bars 9 acting together to form an extensible bracket.

(PATENT 'oFFTiOE. Y

A screw-adjusted spring clamp passes through the slots 8 in the bars6 and 7 and holds their outer ends in whatever position they may be placed in.v This clamp consists of a bolt 10 passing through the slots 8 one of the bars 7 by its head 11 and having a thumb-nut 12 at its other end and a Washer 13 between the thumb-nut and the other bar between the thumb-nut 12 and the washer 13 and is adapted to be compressed by the thumb-nut and to press the tween the two bars 7, thus holding them all in the adjusted position and yet allowing them to be moved therefromwhenever de- .sired [without touching the thumb-nut. If, however, the bars 6 and 7 tendto slip out of the said adjusted. position, the thumb-nut tween is sufficient -to hold them. A goose the end bars l6 16 being only one-half-as long as the bars 9, by means of a spring clamp similar to the clamp above described. We prefer to form the pivots of the bars forming the bracket hollow, as shown in the drawings, and in this case the electric cord 17- passes through the upper. pivot joining the bars 7 to the first bar 9. and then down the said bar 9 and through the pivot at its lower end to the other side-of the bracket and following the second bar 9 to the pivot at its upper end, and so on following a set of said'bars 9 from end to, end of the bracket and passing "from side to side thereof, and it secured to the end thereof. I 5 however, solid pivots are used, the saidxcord follows the same course but is kept on one side'thereof and is secured at the pivots by any suitable means.
