WINDOW-SHADE ADuUsTER.

SPECIFICATION forming part of Letters Patent No. 777,671, dated December 20, 1904.

Application filed March 26,1964. Serial No. 200,110.

To {all} whom t may concern:

Be it known that I, ERNEST T. FRY, a citizen of the United States, residing at Mount Jackn son, in the county of Shenandoah and State of Virginia, have invented certain new and useful Improvements in VVindow-Shade Adjust ers, of which the following is a specilication.

This invention relates generally to windowshades, and particularly to means for vertically adjusting' the shade-rollers and with them the shades themselves- It is well known that it is a great conven ience in the use of window-shades to be able to readily and quickly adjust them and their supporting-rollers to bring the rollers nearer to or farther from the top of the windows.

The object of the present invention is to provide improved means whereby a window-shade roller may be thus adjusted in order that light may be admitted above the shade or air permitted to flow freely into or out of the room to regulate the temperature or change the air therein.

With this object in view the invention consists in the improved construction, arrange ment, and combination of the parts of such an adjusting device, all as fully described hereinafter and afterward specifically pointed out in the appended claims.

In order that others may be enabled to construct and use my invention, I shall now proceed to fully describe the construction and operation of its several parts in connection with the accompanying drawings, in which Figure l represents in front elevation part 0f a window-frame with my invention in place thereon, the shade and roller beingI shown raised in full lines and lowered in dotted lines. Fig. 2 represents in side elevation part of the frame with the shade and rollerin their lower positions. Fig. 3 represents in detail 1n side elevation one of the bracket-arms, part thereof being broken away. Fig. 4L represents in detail the hook for retaining the shade and roller raised. Fig. represents in detail the hook for retaining' the shade and roller lowered. Fig. 6 represents in front elevation the window-:frame with the top broken out and the lower part broken away, showing the rolleroperating means -vertically adjustable on side rods. Fig. 7 represents in side elevation one of the side rods with a slidable rockshaft bearing thereon, the rod being partly broken out. Fig. 8 represents in detail part of the operating-rod and its angular end.

Like reference characters niark the same parts wherever they occur in the several ligures of the drawings.

Referring specifically to the drawings, 1 indicates the top, and 2 and 3 the sides, of thc window-frame, which may be of any suitable form or size.

At 4f 4 are secured to the sides of the frame I suitable bearings, which may be ordinary screw-eyes or staples. to support a rock-shaft 5, which carries at each end an arm, as at 6 and 7, capable of being turned to the upper position, as shown in Figs. 1 and 6, or the lower position, as shown in Fig. 2 and in dotted lines in Fig. l. rIhese arms form rollersupporting brackets, the arm 6 being provided with the usual round hole to receive the rigidly-attached pintle 8 and the arm 7 with a T-shaped recess or notch 9 to receive the angular spring-impelled pintle l0 of any ordinary spring shade-roller 11. The arms 6 and 7 may be made integral parts of the rockshaft 5; but I prefer to make the arm 7 separate therefrom and secured rigidly thereon in any suitable manner-such. for instance, as by means of a set-screw IQ-the shaft entering a hole 13 in said bracket-arm 5.

By mounting the shade-roller in the bearings in the usual manner the shade and roller may be adjusted near to the top l of the frame by turningI the bracket- arms 6 and 7 into ver tical positions along the sides 2 3 of the frame, so that the shade will cover the extreme upper portion of the window, or they may be adjusted to their lower position by turning the bracket downward, bringing the roller to a position about the distance of two lengths of the bracket-arms below the top of the window, so that light and air may be admitted through the upper part of the window. It being necessary to hold the shade-roller 11 in either its upper' or lower position the bracketarm 7 is provided with a vertical slot 14, eX- tending from the hole 13, in which the rockshaft is secured, nearly to the notch 9, which forms the bearing for the angular pintle 10 of the roller, as best shown in Fig. 3.

At 15 is indicated an elastic wire or metal rod provided with an eye 16 or other suitable handle at its lower end and with an arm 17, bent at a right angle to its upper end andannularly grooved near its outer end, Jforming a shoulder 18, a head 19, and a reduced stem 2O between them.

At 21 I show an upturned hook and at 22 a straight hook, both secured in the frame, the former at the height of the bracket-arm 7 when raised to its highest position and the latter in position to engage the wire or rod 15 when in its lowest position. The reduced stem 20 is of a suitable thickness to slide freely in the vertical slot 14, and the parts are assembled by slipping said stem into said slot from thehole 13 in arm 7, which receives the rock-shaft, securing the rock-shaft in its bearings and in said opening, thereby preventing the escape of the stem from the slot and mounting the shade-roller 11 in its bearings in the bracket- arms 6 and 7. Normally the roller would assume its lower position, as

'in Fig. 2, in which the reduced stem 2O ot' arm 17 will hang in the end of the slot nearest the shade-roller bearing and the rod 15 lie against the side of the frame, being held slightly oi the frame by the eye or handle 16 at its lower end, when it may be secured against easy displacement by springing it under the straight hook 22, whereby the shade and roller will be held against flapping or swinging outward under the influence of wind entering the window when open.

To adjust to and maintain the roller in its upper position, it is only necessary to withdraw the rod 15 from under the hook 22, push it upward, thus turning the rock-shaft and carrying the roller upward until the arm 17 can be engaged over the upturned hook 21.

In order to permit of the adjustment of the height of the shade-roller beyond the limit of about twice the length of the bracket- arms 6 and 7, I provide heavy wires or rods 23 in staple form, having angular ends 24, formed as pins, by which I secure the rods in place on the frame, upon which rods I mount slidable blocks 25, provided with openings 26 to form bearings for the rock-shaft 5, which blocks may be vertically adjusted and secured in any positions on said rod 22 by any suitable meansas, for instance, set-screws 26. By the vertical adjustment of the rock-shaft (mounted in these slidable bearing-blocks) the limit of adjustment of the shade-roller may be increased at will to the extent of the length of the rods.

Vhile I have specifically described the construction and arrangement ofthe various parts composing my invention, I do not limit myself to such specific constructions and arrangements, as many slight changes therein or variations therefrom might be made Without departing from the spirit and scope of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is#
