The main advantage of this shade bracket is that a person can lower it for adjusting the shade or in changing curtains while standing on the floor, thus eliminating the use of a step ladder and the danger possibly attending such use.
The front elevation of a window with bracket attachment in position is shown in Fig. 1, and a cross section in Fig. 2. The position of the curtain pole when the brackets are lowered is shown by the dotted lines. A detail sketch of the support end is given in Fig. 3 and one bracket is shown in Fig. 4.
The curtain pole A is fastened to the brackets B with 1/4-in. dowel pins, C.
Ill: the Attachments, Supports and Brackets for Holding both Curtain Pole and Shade Roller
Ill: The Brackets as They are Attached to a Window Casing for Lowering the Curtain Pole
These pins and the pole keep the brackets from spreading at the top, so that a shade roller, D, may have its attachments fastened to the inner sides of the brackets. A small pulley, E, is attached to the window casing above the right bracket and a double pulley is located above the left, cords being passed through them, down along the casing to a point within easy reach, and fastened in any manner desired.
All that is necessary to change the curtains or fix a shade is to loosen the cord and allow the brackets to drop down until they may be easily reached. - Contributed by James F. Napier, Montreal, Can.
