H i

50 The upper and. lower longitudinal edges Formed on the free of i this pivoted 1 00 lll locking bar are the opposed cam portions 17 that function in the manner to be presently described in detail.

Suitable finger-engaging projections 18 are formed on the outer edge of the pivoted locking bar 1% adjacent the respective cams 17 whereby to manipulate the locking bar.

When the parts are arranged as shown in the drawing it will be observed that the looking bar 14: is disposed vertically and one end is disposed against the stop 11 while the other end rides over the beveled portion 13 of the tongue 12 and this tongue prevents casual movement of the pivoted locking bar.

\Vhen in this position, the cam portions 17 cooperate with the inner faces of the respec tive curved flanges 3 thus forcing the slide plate 7 against the base plate 1 and further maintaining the tooth in locking engagement with one of the grooves or serrations 5 w 'fixed position on the base plate, a stop formso that the fixture is locked in its properly adjusted position.

By grasping a finger piece 18 and turning the locking bar in one direction, the same is moved out of engagement with the flanges 3 and then the fixture is free to slide along in the guideway.

It will thus be seen from the foregoing description, that I have orovided an adjustable shade bracket that can be readily and easily adjusted and there will be absolutely no possibility of the shade fixture becoming loose from its properly adjusted position.

Furthermore due to its simplicity, the shade bracket can be constructed at a very low cost and the same will be strong and durable.

WhileI have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claims.

hat I claim as new is: i

1. In a shade bracket of the class described having a stationary base, the upper and lower ends thereof being bent over to form spaced flanges which are spaced from the front face of the base plate to provide longitudinal guideways, the combination of, a shade fixture including a slide plate adapted to move along the front face of the base plate in the guideways, a bracket arm extending from the slide plate, a locking bar pivoted intermediate its ends on the slide plate, and opposed cains formed on the respective ends of the locking bar for cooperation with the inner faces of the respective flanges to lock the slide plate against the front face of the base plate and maintain the shade fixture in fixed position on the base plate, a stop forming member extending outwardly from the base plate and against which one end of the locking lever is adapted to engage when in locking position, and a spring tongue struck out tudinal uidewa s the combination of a shade fixture including a slide plate adapted to move along the front face of the base plate in said guideways, a bracket arm extendin from the slide plate, a locking bar pivoted intermediate its ends on the slide plate, and opposed cams formed on the respective ends of the locking bar for cooperation with the inner faces of the respective flanges to lock the slide plate against the front face of the base plate and maintain the shade fixture in -1ng member extending outwardly from the base plate and against which one end of the locking lever is adapted to engage when in a locking position, and a spring tongue struck out from the opposite portion of the slide plate for engagement with the other end por tion of the locking lever to prevent casual movement of the locking bar, and a finger engaging projection formed on the outer edge of the locking bar inwardly of the respective cam for use in manipulating the locking bar to move the same into an operative or inoperative position.

In testimony whereof I aflix my signature.
