IMPROVEMENT lN RACKS FOR CURTAIN-FIXTURES.

Specification forming part of Letters Patent No. 137,320, dated April 1, 1873; application filed March 13, 1873.

To all whom it may concern:

Be it known that I, JOSHUA PUsEY, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Window-Shade Racks, of which the following is a specification:

Figure l is a front view, and Fig. 2 a side view, in outline, of my rack, which is composed of two distinct parts: First, a piece of metal, A, about one-sixteenth inch thick, struck out from sheet metal or cast, as preferred, and provided with a longitudinal slot, B, one-eighth inch or more in width, and series of alternate slots or notches G of same width as slot B, into which they open. Slots 0 are slightly inclined upward, and are, preferably, enlarged circularly at their upper or closed ends. At the extremity of slot B is a large opening, D, slightly, greater in diameter than button K, Fig. 2. A is seoured to the window-frame W by screws or nails S. The part of A traversed by slots B and 0 sets off from W, as shown in Fig. 2. The second part ofmy rack is a sheave, E, which is provided with a shank, L, shown in dotted lines, Fig. 2, and a button or knob, K, Fig. 2.

Button K is passed through opening D. Cord H, which goes around the shade-roller above, (not represented in the drawing,) is passed around E. The shank of the latter is then slid into any one of slots 0, as desirable, in order to secure the proper degree of tautness of cord H. Sheave E may be readily shifted from one slot to another by pressing the same downward and sidewise when it is required to tighten the cord.

As the window-shade is raised or lowered the sheave rotates, and it is not apt to become displaced accidentally.

The advantages of the shade-rack hereinbefore described are efficiency, cheapness, and simplicity.

I claim- The arrangement of plate A, provided with slots B and (l, and the sheave E, or its equivalent, provided with shank L and button K, substantially in the manner and for the purpose set forth.

JOSHUA PUSEY. Witnesses:
