CURTAIN-SHADE ADJUSTER.

SPECIFICATION forming part of Letters Patent No. 752,318, dated February 16, 1904.

rppnmion nea. october i2, 190s.

To LZ/Z whom, it may concern: Y

Be it known that I, THoMAs'VVnrr'r, a citizen of the United States, residing at Lexington, in the county of Fayette and State of Kentucky, have invented a new and useful Curtain-Shade Adjuster, of which the following isa specification.

This invention relates to devices -for suspending window-shades at any desired point transversely of the-window-opening, and has and easily applied and operated device whereby the shade-roller may be adjusted bodily to dow and the shade unrolled to cover the whole or a portion only of the window-opening; andthe invention consists of certain novel features of construction, as hereinafter shown and described, and specified in the claims.

In the drawings illustrative of the invention, in which corresponding parts are denoted by like designating characters, Figure 1 is a View of a window with the improvement applied. Fig. 2 is an end view, and Fig. 3 is a side view, enlarged, illustrating the construction more fully. Fig. 4 is an end view of theV curtain-roll detached.

The improved device may be applied to any of the ordinary spring curtain-rollers in coinmon use and to any size of such devices and to any size of window or structure or design of casing, and for the purpose of illustration is shownvapplied to a conventional form of window-casing 10, having the usual sash 11.

Attached to the casing at each side above the sash are cord-guides, such as screw-eyes 12 13, through which cords 14 15 pass and connected by one end to a ring 16, from which a single cord 17 extends downwardly to a catch 18 on the casing convenient to the hand of a person on the floor of the room.` By this arrangement it is obvious bothl the'cord portions 14: 15 may be drawn through' the guides 1213 by operating the single-cord portion 17 and held at any desired point by inserting the single-cord portion in the catch 18.

Attached by one end at 19 to the lower end Serial No. 176,735` (No model.)

of the cord portion 15 is a'bracket or hanger 20 of elongated form and having a hub 21 at its lower end provided with a transverse circular aperture for the circular or revolving pintle 22 of a curtain-roller 23, and similarly connected, as at 24,110 the end of the cord portion 14 is a similar bracket or hanger 25, having an elongated hub 26 at its lower end, through which an elongated transverse aperture 27 is formed for the flattened stationary pintle 28 of the curtain-roller. 4

The hub 26 is provided with a set-screw 29, operating in the aperture 27 to secure the hat pintle 28 i'nnrnovably therein. The elongated aperture 27, it will be noted, is inclined to the longitudinal plane of the bracket or hanger, so that the iiattened pintle 28 is correspondingly inclined to bring the gravity-pawls 30 31 in the end of the roller into the best position to quickly act upon the cavities formed for them in the pintle in the rear of the flattened portion iu the usual manner. The pawls operating entirely by gravity, the pintle 28 Amust be held precisely in proper position to receive the pawls as they fall inwardly, (otherwise they would not be eiiectiva) and the rela- 'tive positions of the' cavities and the flattened exterior portion which enters the aperture in the bracket is such that the iiattened portion must necessarily bev supported at an angle to the vertical or at an angle to the longitudinal plane of the bracket which hangs in a constant vertical position. The inclined position of the pintle and the means whereby'this position is constantly maintained is therefore an `important feature of the invention and renders the bracket 2O to prevent the bracket from becoming detached from the roller.

The cord employed may be of any suitable quality or size and of any suitable strength to resist the strains to Which it will be subjected.

The bracket members Will be of metal of suitable strength and may be plated or other- Wise ornamented or protected.

The catch 18 for supporting the free end of the draw-cord portion 17 consists of a Wire formed with a return-bend and secured at one end by a staple 34 and at the other end by a screw 35, With freefend 36 of the return-bend curved outward to form a resilient receptacle for the cord, as shown. By this simple means the cord portion 17 is detachably held and may be very quickly attached and detached When required. The roller 23 may. thus be very quickly moved bodily longitudinally of the Window-opening and supported at any desired point and the curtain unrolled to any desired extent to cover or fshade any desired portion of the Window-opening.

Having thus described the invention, What is claimed is- In an adjustable curtain-fixture, a bracket suspended by one end and free to swing at the other end, the free end having a laterally-extended hub provided with a rectangular aperture arranged at an oblique angle to the longitudinal plane of the bracket, for supporting the flattened pintle of a curtain-roller, and a set-screw operating longitudinally through said hub to engage-the edge of said pintle and maintain the roller immovably in position.

In testimony that I claim the foregoing as my oWn I have hereto aHXed my signature in the presence of two Witnesses.
