WINDOW-SHADE.

EIDECIFICATIQN formmg part of Letters Patent No. 669,321, dated March 5, 1901.

Application led March 24, 1900. Serial No. 10,078. KNO mOdel-J To all whom, it may concern..-

Be it known that we, DAVID R. HOLWAGER and EDWARD MARSHALL, citizens of the United States, and residents of Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Vindow-Shades; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which il. appert-ains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l ot' the drawings is a perspective View of the invention as applied. Fig. 2 is a detail sectional View illustrating the operation of the lever K. Fig. 3 illustrates the lever K in detail. Fig. 4 isa transverse seclion of our curtain-roll, showing the curtain. Fig. 5 is a longitudinal section of the curtainroll. Fig. o is a detail view of slide E.

Our invention has relation to windowshades; and it consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings the letter A indicates a window-frame to which the shade is applied.

B represents a window-shade, to the middle ot' which is secured a roll C transversely, said roll being preferably made of pasteboard.

D D represent the upper and lower sticks of the shade. Y

E is a slide for the ratchet e, which is attached to said slide. The slide is provided with perforations at ct ct for the lateral wire guide F, which extends vertically from the top to the bottom of the window-frame, being attached by its ends to screw-eyes b b or other fastenings. To the end of the roll C'is attached a pawl device c of ordinary construction, its spring c being Within the roll, as shown.

I-I indicates a trip-cord hanger, which is secured to the top of the window-frame at its middle portion. The hanger is provided with two bosses or rollers 7i h in its upper portion between its parallel walls, and below said rollers, pivoted to said walls near their outer edges, is a drop-lever K, which has a loop 7o at its outer end. The inner arm of the lever when in nearlyhorizontal position is designed to engage a cord a', which is attached to a screw-eye at the middle of the upper stick of the shade. This cord passes over the small rollers 71 h and down through the loop la of the catch-lever K. l

The shade having the roller attached to it at its middle portion is arranged for very rapid action, as it will roll up VAor unwind both the top and bottom portions of the shade at the same time, the roller and its bracket rising or falling as the shade is wound or unwound therearonnd. It is easily accessible,when necessary, for readj ustment. It is not apt to pull loose from the shade when the latter is drawn down in a hasty manner, as it is not attached fixedly to anything except the shade.

The entire shade, with its roller, can be raised or lowered to any part of the window by manipulating the cord z. When the cord is pulled down, it draws down the outer end of the lever K and is then free to pass, so that the shade can be pulled upward or allowed to fall downward. Vhen the cord is freed, the catch-lever falls back and engages the cord, holding it against the back wall of the hanger, so that the shade is retained in position. Therefore a curtain of any vertical extent can be arranged at any part of the window by a simple manipulation whenever desired.

The guide-wire and slide connecting the roll to the window at the side hold the shade in such a manner that it will bring it back to position when disturbed by the hand or by the action of wind.

It will be noted that owing to the fact that our curtain and its roll are freely suspended from the operating-cord and owing to the check-lever controlling such cord both halves of the curtain may be wound around or un- Wound from the roll at the same time to decrease or increase the width of the curtain by a simple manipulation of the suspensioncord, the lower half of the Curt-ain being held stationary, or by pulling upon and releasing the lower halt' of the shade and that the curtain as a whole and itsroll may be raised or lowered to shade any part of the window by simply manipulating such suspension-cord.

IOO

Having described this invent-ion, what We claim, and desire to secure by Letters Patent, is-

l. A window-shade, comprising a curtain, a roll having a square pintle and secured to the middle portion of said curtain, spring devices for winding or unwinding both halves of said curtain at the same time around or from said roll, asuspension-cord for said curtain and roll, means for preventing the square pintle of said roll from turning when the curtain is Wound or unwound and a check-lever for controlling the movement of such oord by manipulation of such cord, whereby said roll, and the curtain as a Whole, may be raised or lowered to any point in the Window, and both halves of the curtain Wound or un Wound around or from said roll, by a simple manipulation of such cord, the lower half of the curtain being held, or by pulling upon and releasing the lower half of the curtain, substantially as specified.
