IMPROVED WINDOW-SHADE FIXTURE.

TO ALL WHM IT MAY CONCERN: l

Be it known that we, FREDERICK A. SEBORN, DAVID R. DUNLAP, and JOACHIM F. C. GEIST, of Zanesville, inthe county of Muskingum, 1n the State of Ohio, have invented a new and improved Fixture and lCombination for Raising and Lowering Window-Curtains; and we do hereby declare that the following is a full and exact description thereof,reference being had to theaccompanying drawings, and the letters of referencemarked thereon.

The nature of our invention consists in so'arranging the curtain, roller, and pulleys with the cords, that the curtain may be rolled either from the bottom to the top, or from the top to the bottom, or in both directions at the same time, so that the upper sash may be lowered, andthe current of air pass unobstructed over the curtain and. roller, or the lower one may be elevated, andthe current pass unobstructed into the room, or both may bedone ut tho same time. i A y The advantage of this invention, to secure perfect ventilation from the top, and at the same time close thev lower part ofthe window, must be obviousto all, and this perfect ventilation from 'the top can besecured without the disagreeable consequence, resulting from stationary rollers, of having the curtain either fixed to the sash, or, if not soxed, permitting the current o'fa'ir passing through the opening caused by lowering-the upper sash blowing the curtain into the room.

To enable others skilled inthe art Ito make and use our invention,we proceed to describe its construction and operation. p v v The accompanying drawings represent an ordinary window, so constructed th'at the upper sash may be lowered by weights or springs, and the lower one elevated in the same manner; and they show that the upper sash is lowered, and also show the curtaiuand roller marked in the drawings A. The pulleys are one at each upper corner of the window, and-are markedB BA. The cords are marked respectively,C C, E E, and F, .and the small hooks attached to the ends of the roller marked D D. f One of the cords C is lattached to the hook D, at one end of the'roller, and the otherat the other end. They are-then 4passed over the pulleys B B, andkcome together and are fastened to the small button marked G; on the side or casing of the window. By liftingthe cords C C from their fastening on the button G, the roller A'will fall or be lowered, and by pulling 'che cords downpthe roller will be raised. The cords E E pass once, around the roller at or near eah end, in a little'groove for the purpose, and are fastened a't'the top and'bottom of the window. As the roller falls or isA lowered, the cords E E, by being thus passed around the roller, as already stated, cause vthe roller to revolve, and thus roll the curtain from the top downwards. When the ourtain is elevated to the desired height, and the cords C C fastened .to keep it in its place, by pulling the cord F, the roller revolves, and the curtain is raised 'from thebottom, the hooks D Dbeing so fastened to the ends of the roller as to permit it to revolve. Y I

Instead of having the pulleys B B fastened to the upper corners of the window-frame or casing, they may v be placed in a moulding or bar which may be fastened acrosst'he window, either for the purpose of being more v ornamental or more'couvenient, as' may be desired. l

The' cords E E, not only in passing around the roller, actin rolling the curtain, but also serve to keep the same in its place. l i

We are awaro that a cord similar to the cord C has been employed by Tanner and Gorton and 'other`s,'to

raise and lower both ends of the upper roll at once; and we are also aware of G. M. Whites patent, dated August 7, 1866, inwhich a fixed rope, running around one end of each: roll, is employed'for the lpurpose of4 rota-ting the rolls as they are raised and lowered. We are also aware that a cord, F, operating to Iloll up the curtain, has been used ever since curtains were made. We do not claim theseA different parts by themselves, but simply the combining of them all together in a single device, whereby they are made to operate each in connection with the other, andthe advantages of all are utilized to the` fullest extent.

What We claim as new, and desire to secure by Letters Patent, is- The arrangement of the cord C, pulleys B B, roll A, fixed cord E, and cord F, substantially as shownv and escribed.
