CURTAIN-FIXTURE.

SPECIFICATION forming part of Letters Patent No. 673,870, dated May 14, 1901. Application filed March 30. 1899. Renewed April 4, 1901. Serial No. 54,358. (No model.)

To a/ZZ whom, it may concern:

Beit known that I, ARTHUR HARRIS, a citizen of the United States, residing at Dover, in the county of Kent and State of Delaware, have in vented a new and useful Curtain-Fixture, of which the following is a specification.

This invention relates to curtain-fixtures of that class including a shade-roller mounted to be raised and lowered; and the object of the invention is to provide a simple and effective device of the character specified, including means for positively locking the shade-roller in a shifted position, so that the shade thereon can be adjusted without fear of disturbing the roller.

With these ends in View the invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand the invention, I have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a front view of a window-frame of ordinary construction, showing my curtain-fixture applied thereto and representing the shade-roller as being lowered. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal central section through the shaft which sustains the cord-winding mechanism. Fig. i is a perspective view of the catch for the pull-down cord, and Fig. 5 is a similar view of one of the sliding brackets.

Like characters denote like and corresponding parts in each of the several gures of the drawings.

In the drawings I have represented a window-frame 2 of ordinary construction, and the saineV may be provided with the usual sashes.

The opposite side bars of the window-frame support the guides for the curtain-roller 3, which is provided with the shade 4, adapted to be wound thereon through the agency of the well-known spring mechanism, and this roller is supported for vertical movement hy the brackets 5, it being provided with projecting journals extending through openings in said brackets. The brackets consist of duplicate plates, embracing and sliding on the vertically-disposed guide-rods 6, arranged in pairs and secured to the superposed fixed brackets 7, secured to the window-frame at opposite sides of the opening therein. The duplicate plates of the brackets are provided with complementa] curved pockets, which receive the guide-rods 6, and such construction insures the proper movement of the shaderoller as it is raised and lowered, said roller being lowered for the purpose of securing ventilation through the upper part of the window-opening.

The upper fixed brackets 7 support the shaft S, consisting of the rotative section 8 and the fixed or non-rotative section 9, and said rotative section of the shaft is provided near its opposite ends with the spools 10, upon which the cords 12 are adapted to be wound, the opposite ends of the cords being passed through openings in the sliding brackets 5 and knotted to secure them in place. The spools can be secured to the rotative shaft-section 8 in any convenient manner, and said shaft-section is surrounded by the longitudinal sleeve 13, which is lixed tothe spool nearest the stationary shaft -section and which abuts against the shoulder 14 on the rotative shaftsection. The longitudinal sleeve 13 incloses the coiled spring 15, which surrounds the shaft S and the opposite ends of which are secured to said sleeve and to the stationary shaft-section 9. When the shade-roller is in its uppermost position, the sliding brackets 5, which support the same, bear against the xed brackets 7, and when said roller is lowered the winding-spring 15 will be compressed by the rotation of the sleeve 13, which, it will be remembered, is connected to the righthand spool or drum 10, and when the roller is released the spring will serve to rotate the sleeve 13, and thereby the rotative section 8 of the shaft, so as to wind the cords 12 on the two spools and elevate the roller.

Means are provided for locking the roller in its shifted positions, and when the roller is locked the shade thereon can be manipulated to any extent without fear of accidentall)7 releasing the roller. The cord 16 is connected to the right-hand sliding bracket 5 by being passed through an opening in the latter and knotted at its upper end, although it may be IOO otherwise connected, and said cord is provided with a series of stops, as the knots 17 thereon, which are adapted to engage a suitable catch, as 18, secured to the window-frame, whereby .the shade-roller can be held down. The catch 18 consists of a plate having a projection or lug near its center, in'which the notch or recess 19 is formed, which notch or recess is adapted to receive the cord 16, and when one of the knots on said cord is under the projection of the catch the shade-roller will be held down. stops or knots may be employed. The cord 16 constitutes a simple means for lowering the shade-roller, it being understood that when it is grasped and drawn down said roller can be lowered, and the two pairs of parallel guide-rods, upon which the slidable brackets 5 are mounted, serve to properly guide the roller as it moves up and down.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claim may be resorted to without departing from the spirit or sacricing any of the advantages of this invention.

Having thus described the invention, what I claim is- In a curtain-fixture the combination of the Any number of these curtain-roller, of slidable brackets each comprising two plates having oppositely-curved portions at each edge resulting in the formation of two longitudinal bearings, a pair of supporting-rods passed through the bearings of each bracket, each of said brackets having an opening midway between its bearings for the reception of said roller, a second roller rotatably mounted above the irst named roller and having a spring which exerts a constant rotating pressure thereon, cords connected with the second roller and adapted to be wound thereon, said cords having their opposite ends passed through openings in the brackets whereby said brackets maybe raised and lowered as the uppermost roller is rotated, a slotted stud mounted adjacent one of said pairs of rods and a cord passed through Witnesses:
