ADJUSTABLE CURTAIN-FIXTURE.

SPECIFICATION forming part of Letters Patent No. 776,285, dated November 29, 1904.

Application filed March 14, 1904. Serial No. 198,041. (No model.)

To (all whom it may concern:

Be it known that we, EMIL G. ALBER and FRANK E. H nnencitizens of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Adjustable Curtain-Fixtures, of which the following is a specification.

This invention relates to improvements in adjustable curtain-fixtures; and our object is to provide a simple device for adjusting curtains vertically, so the latter may be readily lowered from the upper portion of a windowframe for the admission of air and light when desired.

The invention consists in the novel construction, combination, and arrangement of parts hereinafter described, and pointed out in the claims, and in order that it may be fully understood reference will now be made to the accom panying drawings, in which Figure 1 represents a broken front elevation of a window-casing provided with our improved fixtures. Fig. 2 is an enlarged vertical section of one of the fixtures, taken on line H II of Fig. 1. Fig. 3 is a broken detail perspective view of the upper portion of one of the fixtures looking from the rear and showing the means for locking the bracket-bar from downward movement. Fig. 4is a broken de tail perspective view of a portion of the back plate forming part of the invention. Fig. 5 is a broken detail perspective view of the lower portion of one of the fixtures with back plate removed. Fig. 6 is a detail perspective view of the lower portion of the back plate, the bracket-bar, and handle for operating the latter.

In carrying out our invention we employ a pair of curtain-fixtures, which being duplicates we will for convenience proceed to describe but one of them.

1 designates a back plate provided at its opposite ends with apertures 2 for the reception of tacks or screws whereby it is secured to window-casing 3. Said back plate is provided with a series of inwardly-extending projections 4 and a pair of marginal flanges 5, formed integral with its longitudinal sides.

6 designates a bracket-bar slidingly arranged between fianges 5 and provided at its lower end with a handle 7, carrying a spring member 8, the inner reduced end of which extends through a slot 9 in the face of bracketbar 6 for a purpose hereinafter described. The lower end of bracket-bar 6 is provided with a transverse roller 10, which travels on the window-casing when the bar is raised or lowered, and thus prevents scratching or otherwise marring the finish of the casing. The upper portion of bracket-bar 6 is provided with a spring-pawl 11, adapted to engage any one of projections 4, and thus prevent the bracketbar 6 from slipping downwardly beneath the weight of bracket 12, secured to its upper end, and curtain 13, carried by the brackets; but said spring-pawl will permit the upward movement of bar 6 by freely sliding over the upwardly-inolined portion 4 of projections 4. When it is desired to lower bracket-bar 6, springpawl 11 is held clear of the upper square ends of projections 4 by spring member 8 through the instrumentality of a pawl-operating bar 14, having an aperture 15 near its lower end for the reception of the reduced end of spring member 8, and a slot 16 near its upper end, through which the lower free end of the spring-pawl projects. By depressing the inner portion of the spring member into contact with handle 7 bar 14 is drawn downwardly, so that the upper edge of slot 16 will contact with and press the free end of the spring-pawl out of line with projections 4, so that the bracket-bar may be lowered to the position desired. Bar 14 is operatiyely secured to bracket-bar 6 by guides 17, formed integral with the latter. The upward movement of bar 6 is limited by shoulders 18 on handle? contacting with the lower ends of flanges 5.

From the above description it is apparent that we have produced a curtain-fixture which is simple in construction, inexpensive to manufacture, and easy to operate. It is also apparent that the brackets 12 can be adjusted to retain the curtain-roller in a horizontal position, and thus prevent the curtain from rolling upwardly thereon at an oblique angle, which occurs when the roller is secured in other than a horizontal position.

' Having thus described our invention, What We claim, and desire to secureby Letters Patent, is-

1'. A curtain-fixture Consisting in a back plate having inwardly-extending projections, a bracket-bar slidingly secured to said back plate, a pawl secured to the bracket-bar and adapted to engage the projections one at a time, and a pawl-operating bar slidingly secured to the bracket-bar.

2. A curtain-fixture consisting in a back plate having inwardly-extending projections, a bracket-bar slidingly secured to said back plate, a handle attached to the lower portion of said bracket-bar, a spring-pawl secured to the upper portion of the bracket-bar and adapted to engage the projections, one at a time, and a pawl-operating bar slidingly secured to the bracket-bar.

3. A curtain-fixture consisting in a back plate having inwardly-extending projections, a bracket-bar slidingly secured to said back plate, a handle secured to the bracket-bar and adapted to engage the projections, one at a time, a pawl-operating bar slidingly secured to the bracket-bar, and a spring member carried by the handle and engaging the pawloperating bar.

4:. A curtain-fixture consisting in a back plate having inwardly-extending projections, marginal flanges formed integral with the longitudinal sides of the back plate, abracketbar slidingly secured to the back plate, atransverse roller secured to the lower end of the bracket-bar, a paWl secured to the upper portion of the bracket-bar and adapted to engage the projections, one at a time, and a pawl-operating bar slidingly secured to the bracketbar.

In testimony whereof We affix our signatures in the presence of two Witnesses.
