WIN OW-SHADE PULLEY.
Application filed July 21, 1925. Serial No. 45,140.
This invention aims to provide novel means for guiding and belaying the cord whereby a window shade or other closure 1s controlled.
Figure 1 shows in bottom plan, a device constructed in accordance with the invention, parts being broken away and parts appearing in section;
Figure 2 is an elevation wherein the pulley is viewed edgewise;
Figure 3 is a side view of the pulley;
Figure 4; is an elevation o1 the complete device, the casing being in operative position, and being turned through an arc of about 90 from the position of Figure 1;
Figure 5 is an elevation of the base, a part thereof being in section,
The numeral 2 designates a cup-shaped casing within which is located a base 4t having a thinned edge 14:, the casing 2 being crimped upon the thinned edge 1 of the base, as at 15, the casing 2 being prevented from turning by means of securing elements 7, such as screws, mounted in the edges 01 the casing and engaging the base e. Thev base t has a central opening 16. A peripherally grooved pulley 3 is located within the casing 2 and rests against the central portion of the base 4, the pulley having an opening 23. A combined securing device and axle 1, such as a screw, passes through the casing 2, through the opening 23 of the pulley 3, and through the opening 16 of the base 4, the rear end of the member 1 engaging a window casing (not shown) and the head of the member 1 engaging the outer wall of the casing 2, to hold the device in the position of Figure t. The casing 2 is provided in its side wall with a circumfer-' cntial slot 10 which tapers as it extends circumi'erentially, the wider end of the; slot being marked by the numeral 5. The wider end 5 of the slot 10 is located a little below the horizontal line passing through the axis of the screw 1, and, from that point, the slot extends about three-quarters of the way around the casing 2, and terminates at a point almost directly above the axis of the screw 1, as shown in Figure 4:. The numeral 11 marks a closure of any kind, such as a curtain, to which is connected one end 015 a flexible element 9. The flexible element 9 is looped into the grooved tread of the pulley 3. When both runs of the flexible element are parallel, the flexible element will pay freely through the wider part of the slot 10, thereby permitting the operator to raise or lower the closure 11, the pulley 3 rotating on the screw 1. The operator can pull the free end of the flexible element 9 laterally a little, as shown in Figure 4, and jam the flexible element in the restricted part of the slot 10, whereupon the flexible element will be held, and the curtain 11 will be retained in any position to which it may have been adjusted.
I claim 1. A device of the class described comprising a cup-shaped casing, a combined securing device and axle mounted in the casing, a pulley located within the casing and journaled on the securing device and axle, the pulley having a grooved tread, and the cats ing being provided with a circumferentially extended and circumterentially tapered slot alined with the grooved tread of the pulley.
2. A device of the class described, constructed as set forth in claim 1, and further characterized by a base within the casing, and against which the pulley bears, the securing device an'd axle passing through the base.
In testimony that I claim the foregoing as my own, I hereunto set my hand.
ZEN AS H. WILLIAMS.
