VERTICALLY-ADJUSTABLE SHADE HANGER.

Application filed November The invention relates to vertically adjustable shade hangers and has for its object to provide a hanger carried by a window frame and provided with means whereby a shade roller may be adjusted to various positlons 1n a vertical plane for allowing light to pass through the Window frame above or below the shade, thereby allowing the sun or light to be cut out in any desired position and at the same time obviating the necessity of excluding all of the light orsun.

it. further object is to provide a vertically adjustable sh ade hanger comprising brackets secured to the inner sides of the window frame adjacent the upper end thereof and a shaft connecting sprockets within said brackets, said shaft being adjustable 111 hr: 1th for accommodating the device to various widths of frames and at the same time forms means whereby the sprockets will simultaneously rotate when a pull is imparted on either of the relatively long sprocket chains which extend. over the sprockets. Also to provide means whereby a shaderoller may be supported from brackets carried by one of the sides of the sprocket chains.

A further object is to provide the sprocket carrying bracl tets with lugs adapted to be received in one of the links of the sprocket chains for holding the shade in any adjusted position.

With the above and other objects in View the invention resides in the combination and arrangement of parts as hereinafter set forth, slum ii in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without dcpartiiig from the spirit of the 1nvention.

In the drawings:

Figure 1 is a perspective view of the windbw vfran'ie showing the device applied thereto.

Figure 2 is a side elevationcf one of the brackets of the shade hanger showing the sprocket therein and the s arocket chain.

Figure 3 is a side elevation of the shade hanger bracket on the other side of the window frame.

Figure 4 is a perspective view of the ad justing rod.

Figure 5 is an enlarged front elevation of the vertically adjustable shade hanger.

Referring to the drawings, the numeral 1 designates a conventional form of window 5, 1925. Serial No. 66,977.

frame, 2 the lower sash and 3 the upper sash thereof. Secured to the inner faces of the vertical sides of the window frame 1 adjacent their upper ends are casings 4, in which casings are disposed sprocket wheels 5. Sprocket wheels 5 are provided with angularly shaped shafts 6, which extend through apertures in the casings 4, and into an angular shaped sleeve 7, therefore it will be seen that when either sprocket is rotated, the other sprocket will simultaneously rotate therewith. Extending over the sprockets 5 are sprocket chains 8, which are relatively long and extend to a point adjacent the lower end of the Window frame 1 where they may be easily grasped by the operator. The ends 9 of the sprocket chains are secured to hooks 10 of cished members 11, and which dished members are provided with conventional shade pintle receiving apertures 12 for the reception of the piutles 13 of the shade roller 14:, which shade roller is of a conventional form and is provided with a shade 15, therefore it will be seen that when the roller 14: is adjusted to a desired elevation the operator may manipulate the shade 15 to cover the lower portion of the window without obstructing the passage of light through the upper portion of the window.

Casings 1d at the front and rear sides thereof are provided with lugs 16, which after the adjustment of the device are received in any of the links of the sprocket chains 8 upon an outward" movement of the sprocket chains as shown in dotted lines in Figure 2, therefore it will be seen that the weight of the shade roller and the shade 15 will prevent disengagement of the lugs 16 with the chain until a downward pull is imparted on the vertical portion of the chain which does not support the shade roller. It will be noted that lugs 16 are disposed at op posits sides of the casings 4, consequently either casing may be secured on either side of the frame thereby obviating the making of-right and left handed casings. Pintles 13, if desired may be provided with pins 17 for preventing the same from coming out of the apertures 12, incident to any side movement of the dished members 11.

From th above it will be seen that a vertically adjustable shade hanger is provided whereby a shade roller may be adjusted to various elevations for covering any portion of a window, the device is simple in construction, the parts reduced to a minimum and the device easily and quickly applied to a conventional form of Window frame Without varying the construction thereof.

Theinvention having been set forth what is claimed as new and useful is A vertically adjustable shade hanger comprising a casing having its lower end open,

a rotatable sprocket Within said'casing, the front and rear sides of said casing bemg open 10 from its bottom upwardly to substantially the horizontal center of the sprocket, a linked chain extending over said sprocket, the opposite sides of the casing at the upper ends of the openings in the front and rear sides thereof being provided with downwardly and outwardly curved lugs adapted to be received within the respective links of the chain when said chain is moved outwardly.

In testimony whereof I afiix my signature.
