JAMES LLOYD OLIVER, OF BOSTON, MASSACHUSETTS.

Letters Patent No. 109,241, dated November 15, 1879.

IMPROVEMENT I N CURTAIN-FIXTURES. t

The Schedule refen-ed to in these Letters Patent and making part of the lame.

To all to whom these presents shall come:

Be it known that I, J AMES LLOYD Omvnn, of Boston, in the county of Suiolkand State of Massachusetts, have made au invention ot' a new and useful Mode of Mounting or Hanging \Vindow-Curtains, or the same and their' rollers; and do hereby declare the following to be a full, clear, and exact description of my invention, due reference being had to the accompanying drawing making part of this specification, and in which- Figure l is an elevation;

Figure 2, a vertical section; and

Figure 3, a horizontal section of said invention.

This invention has reference to a novel and useful mode of mounting a window-curtain roller, or roller and curtain, whereby the altitude of the saine with respect to the window'is varied and adjusted at pleasure, without interfering with the proper action of its ordinary functions, the purpose ot' suoli an invention being to enable any portion of a window to be left uuobstructed or shaded by the curtain, as the case may be, as well as to allow of free passage of air either above or belowsueh curtain," or at the same time both above and below the saine.

This invention consists in mounting or swiveling eachend of a curtain-roller in a sliding block or 'car-` rier, such carriers sliding upon suitable rails or guides 'applied to opposite sides ot' the window-frame, by

I'neaus of which the Ialtitude of the curtain may be varied, as and for the purposes above premised.

The drawing accompanying and illustrating this de.- scrption of my invention exhibits, at A, the frame of a window, of which b b are the side supports or posts, o the upper cross-bar or tie, and l the sill.

In carrying out my invention in one practical form I aiiix to the inner face of each post b an upright rib or spline, c and c', while sliding upon such ribs Imount two carriers or blocks, f g, the opposite ends of the rollcrh being steppedV or swiveled within these carriers, as exhibited.

Although it may be found in practice that the curtain-roller It will suiice to pioperly connect and secure the carriers j' f/ together, I prefer to unite them by a cross-bar, i, extending across the interior of the window-frame, as shown in the drawing hereto annexed.

rlhe gravity of' the curtain and roller and of the carriers fg may, ofcourse, be counterbalanced by a suit-- able weight or spring in a manner which will be understood by any mechanic.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The sliding curtain-roller carriersa fg, connected as described, in combination with the posts b and ribs or splines c c on the inner faces of the same, said parts being arranged for joint operation, as shown and set forth.

JAS. L. OLIVER.
