To all whom, t may concern: i

Be itA known that I, FRED L. BAILEY, "a citia new and'useful Improvement'in Window- Shade Adjusters, of whichthe followingisaJ full, clear, and exactdescription, referencei being had to the accompanying drawings, which are made a partof this specification.

My invention? relates to improvements in the mechanism for lowering'or raising the roller which ordinarily carries the window# shade; and it consists of features of novelty, which will be more fully and perfectly pointed out in they following description, in which Figure 1 shows the window-casing and the shade-adjuster in place with window-shade attached, part of the shade being broken away to more fully show the mechanism ofthe adjuster. Fig.` 2 shows a detail View of one end of the adjuster-frame. Fig. 3 shows an end view of the detail in Fig. 2. Fig. 4 shows a detail guide-rail, the use of which Will be subsequentlyv pointed out. Fig. 5 is a detail cross-section on line 5 5 of Fig. 2. Fig. 6 shows a modification ot' the adjuster-frame. Fig. 7 is a horizontal cross-section on line 7 7 of Fig. 6. Fig. 8 shows a second modication of the adjuster-frame. Fig. 9 is a cross-sectionon line 9 9 of Fig. 8. Fig. 10 shows an alternative form for attaching the lower roller of the adjuster-frame.

The window-casing 1 'has secured on either side a vertical guide-rail 2. This guide-rail is made of metal in the form of a small anglebar, as is clearly shown in cross-section, Fig. 5. A top view of rail 2 is shown in Fig.' 4." These guide-rails 2 extend from the `top of the inside of the window-casing to the window-sill at the bottom. Between these rails is arranged a rigid carrier supporting at its upper end the shade-roll. This carrier,which will be called the adjuster, consists of a triangular frame 3, having small grooved rollers 4 at the upper and lower corners. These rollers 4 engage the guide-rail 2, and the two frames 3 are separated and held rigidly apart by a rod 5. This rod 5 `passes through a collar G on eachof the triangular adj uster-frames and is held secure by a small set-screw orother means of clamping. The sleeve 6 is made so that the rod 5 can pass serai No. 641,723. oro model.) v

through it, in 'this,my adjqsnngthe width `between`the nrollers 4 on thetwo sides of the window.' VA small angle-bracket,7` is secured to the upper partof each of theadjuster- -frames j`and extends out, as shownin Fig. 3, clear overthe frame 3. These brackets support the 'shaderoller8, on which the curtain 9 is rolled. These brackets 7 are madewith a longitudinal slot l0 in their base, so that theyv maybe adjusted to the exact length of the shade-roller 3.A The entire adjuster-:frame -is held infits'relative vertical position by the spring-catches 11, which engage small recessholes 12 in the guide-rail 2. These springcatchesf 11 are released by the cord 13, which passes through an opening in the rod 5 and over a small pulley 14 at the top ofthe win- 1 7o j. The operation of this adjuster is as follows:

dow-casing.

APresuming the window-shade to be in the position indicated in Fig. 1, iirst it fis desired to raise the window-shade to the top of the window. The cord 13 is grasped and gently pulled. It first releasesthe catches, 11 from the holes 12 in the guide-rail 2. Next, further tension put on cord 13 raisesthe adjusterframe vertically. The rollers 4 travel in the guide-rails 2. When the window-shade is high enough, the cord 13 is released. The adjuster-frame will then descend until the catches 11 meet the first of the holes 12, into which they will enter, therebyarresting the downward course of the adjuster-frame. Of courseif Vthe catches 11 happen to be opposite any of the holes 12 when the cord 13 is released they will at once enter such holes 12. It it is desired to lower the top of the window'- shade, the cord 13 is rst tightened enough to release the catches 11. Then cord 13 is gently released, allowing the adjuster and windowshade to descend. The weight of the ad `juster-frame and window-shade being much greater than the strength of the small springs which force the catches 11 into their respective openings 12, the catches will remain dis` engaged so long as there is even a slight tension on cord 13; but so quick ascord 13 is entirely released the catches `11 will at once engage in the nearest opening 12.

Vhen the window frames or casings are not of sufficient depth to place angle-rails, as shown in Figs. 4 and 5, inside the casing,

IOO

then in order to make this invention available in such cases asmall raised rail 15, such will also be found a modified form of catch 11, operating by gravity instead of by spring.

In the rail 15 (shown in Fig. 6) will be found a modiiied form of orifice for the catch 11 to engage with, consisting of a small triangular notch 16. Window-case 1- originally for the use of this form of WindoW-shadeadjuster, a groovedY `rail 17, such as is shown in Fig. 9, may be A mortised into the inside of the casing. In 4 this groove thesmall rollers 4, which iny this case need not be' grooved, Will travel. The

Weight of the adj uster-t'rammand Window-- shade may be counterbalanced by Weight 18,

moving on the inside of the 'casing -1 inV a manner similar to the counterweights for an ordi-- nary Window. Instead of catch 11 being used friction -springs 19 are intended to press against the bottom of the groovedl rail-17,v forming sufficient resistance 'to maintain the frame in any desired position, which can be .l

done by a cord secured tothe cross-bar 5,. f.

In this Way the Window` Where it is desired toplan the` passing over a pulley`14, similar to the cord 13, and also a cord attached to 5 and' hanging directly down. (Not shown.)

Fig. 10 shows a modified form ofl securing the lower of the small rollers 4 by a spring 20, the object of this being to allow for slight unevenness in the rail 2.

Having fully described my invention, the combination I claim is as follows:

1.v In a Window-shade adjuster, the combination of a rod having brackets at either end, the same being laterally adjustable, rollers mounted atthe upper and lower extremities of the brackets, 'guide-rails secured to the Window-frame for engaging the rollers anda catch for holding the frameat any desired position, and shade-roller brackets mountedv upon a frame for holding the shade-roller substantially asdescribed. i

- y2. The combination -ina Window-shade ad- -a -j ust'er of a rod 5, brackets-23; means for adjusting the brackets 3' laterally on the rod 5,

rollers 4 mounted a-t the upper andloWereX- tremities ofthe brackets,guide-rails 2 secured to the Window-frame, brackets 7 for f holding the shade-roller, the-roller y8 for hold# ing the shade andthe catches 11 for securing f the' -frameat any desired position, snbstan-4J tially as described. l Y
