SHADE ADJUSTER.

"Application filed February 16, 1524. Serial No. 693,286.Y

T0 all whom t may concern:

Be it known that l, Lonis SAoKs, a citizen oit' the UnitedStates, residing at Hempstead, county of Nassau, and State of New York, have invented certain new and useful Improvements in Shade Adjusters, of which the following is a specilication.

This invention relates to adjustable supports for window shades, and has for it's main object to provide means, simple in construction, effective in operation, easily manufactured, and durable in use, adopted to adjust the roll of a window shade so that the upper part of the window or any desired portion thereof may be exposed above the shade, and when the upper sash is lowered permit both air and sunlight to enter the rooms or" a house, and all or any desired portion of the lower` partof the window may be covered by the shade.

1With the foregoing, and other objects in View, hereinafter stated, the invention consists of: the novel construction, combination and arrangement or" parts hereinafter more r specii'ically stated, and illustrated in the accompanying drawings, wherein is shown a device embodying the structure of the invention in its preferred form, but it is to be understood that changes, variations and modifications may be resorted to without departing from the scope of the invention.

ln describing the invention in detail reterence is had to the accompanying drawings which form a part of this specification, and4 wherein like characters of reference indicate corresponding parts throughout the several views and wherein:

Fig.Y 1 is a `front elevation of a window trame and a shade, and a side elevation ot a device embodying the invention.

Fig. 2 is a front elevation of the upper portion of side rails, and carriers upon which the ends of a shade roll are mounted.

Fig. 8 is a vertical section of the side rails and carriers shown in Figs. 1 and 2, with the end o't a. shade roll in side elevation.

Fig. 4: is a transverse section taken on the line of Fig. 3, some of the parts being shown in side elevation, and

vFig. 5 is a side elevation of the upper end of a side rail showing a modification ot the invention.

As illustrated in the drawings, 1 represents a window frame having side rails 2 attached to opposite sides thereof, by means ot screws or otherwise. These side rails are provided with a back plate 3 and side plates t inclined inwardly relative to said back plate.

' The side plates 4 are spaced apart at their free margins so as to expose the front plate. 5 of a carrier for the shade roll. The carrier is also provided with a back plate 6,v and side plates 7 inclined inwardly relative to the back plate and terminating in the front plate 5.

The carrier is also provided with end plates 8, one of which is provided with a bracket 9 to support the end of a shade roll. @ne of the brackets is provided with an aperture 10 to hold the round end or pin 11 of the shade roll and the opposite bracket is provided with an open ended s lot 12 to receive the opposite flattened end ofthe roll pin.

The front and back walls of the carrier are provided with apertures to receive a stud 13, which is provided with a head 14, and the portions of the back plate containing its apertures are embossed as at 15, so that the inner end of the stud may have a bearing on the back plate when the pin is retracted.

The stud 13 is provided with a. transverse aperture adapted to receive one`end 16, of a spring, which bears against the back plate of theA carrier, and with a-slot 17, toreceive the other end 18 of the spring, which bears against the front plate of the carrier, and permits-a limited longitudinal movement 'of said stud, relative to the end of the spring engaging said slot. The loop of the spring is referabl elongated so as to bear against said stud and one end of .the carrier and prevent displacement of the. spring.

The inner end of the stud 13 also engages apertures 18 formed in the side rails, and the side walls of the rails are preferably provided with transverse marks 19, arranged in line with said apertures to indicate the position of said apertures.

lVhen the device is in use, the side rails are attached to opposite sides of the window traine, and the carriers are adapted to be moved longitudinally of said rails to the extent desired.

As shown in Fig. 1, the carriers are so arranged as to bring the shade roll below the top of the window frame, and expose a portion of the upper sash above the roll.

When in such position thev studs 13 are in engagement with the apertures 18 of the side rails, and hold the shade roll securely in position, at the same time permitting the lower port-ion of the shade to be adjusted at any desired height above the sill of the window, as in ordinary use. When it is desired to change the position of the shade roll, the studs 13 are retracted against the resistance of the springfconnected therewith, until the studs are free from engagement with the apertures of the side rails, the shade is then free to be moved up or down into a desired position.

The lines 19 indicate the position of the apertures in the back of the carrier and in adjusting the rollto new position the studs are brought into alignment with the marks 19 of the side'rails, and the outward pull on the pins 13 is then relaxed. The studs 13 then come into engagement with the adjacent apertures of the side rails and hold the shade roll in its new position.

As shown in Fig. 1, the side rails are connected with the side bars of a window frame, but the device, if desired, may be connected with a window in a door in the interior of a house, such as the doo-r of a bath room.

In such cases the'side rails of the support are applied to the side of the door adjacent the window, and the bracket 9 is provided with a twisted neck 20 as shown in Fig. 5.

From the foregoing description, taken in connection with the drawings, the construction, inode of operation, and the several advantages of the construction clearly appear.

It will be observed that by means of such construction, the carriers are rmly held within the rails against lateral or torsional strains, and that the carriers may be provided with side, back, front and end. walls of a single piece of metal, thereby reducing the cost of construction to a minimum, and providing carriers that are strong in construction and light in weight.

It will also appear that although the brackets 9 are made of a single thickness of material, bent out from one end of the carrier, the brackets are relieved of all strain because of the fact that the ends of the roll rod pass between the free margins oi' the sides of the rails, whereby the margins of the rails take up any strains that may be exerted o n the shade roll.

W hat I claim as new and desire to secure by Letters Patent, is: v

1. In a shade support, the combination of apertured rails capable of being secured to a window iframe, a carrier enclosed within and movable longitudinally of each of said rails and including front and back walls, a bracket carried by each carrier and eXtending outwardly from its associated rail for` -to va window frame, a carrier having front and back walls enclosed within and movable longitudinally of each of said, rails and also having a bracket extending outwardly from its associated rail for supporting a shade roll, a stud slidable transversely through the walls offsaid carrier and engageable in one of the apertures in said rail, said stud having a s lot therein, and

a spring interposed between the walls of said carrier and having one end engaged in said stud and its other end projecting in the slot in said stud to permit of relative movement of the stud with respect to the spring when withdrawing the stud 'from the aperture in said rail.

3, In a shade support, the combination of rails capable of being secured to window frame, each rail including an apertured back wall and side walls, a carrier having front, back and side walls enclosed within the walls: of said rail and movable longitudinally thereof, the front and back walls of said carrier being provided with aligned openings and a portion of the back wall surrounding the opening therein being embossed and spaced from the back wall of said rail, and a stud extending transversely of lsaid carrier through the openings in the front and back walls thereof and having a bearing upon the edges of said openings when the stud is in an inoperative position, the inner end of the stud being capable of engagen'ient with an aperture in the back wall of said rail when the stud is in operative position.

In testimony whereof I. have affixed my signature. I
