CURTAIN-FIXTU RE.

SPECIFICATION forming part of Letters Patent N o. 739,129, dated September 15, 190B. Application filed August 22, 1902.A Serial No. 120,722. (No modeLl T0 a/ZZ whom it Wawy concern: v

Be it known that I, HENRY D. WHIPPLE, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Curtain-Fixtures, which improvement is fully. set forth in the following specification and shown in the accompanying drawings.

My invention relates to curtain fixtures generally; and it has for its main object an iinproved method of hanging and controlling the curtain-roller.

Another object of the invention is to con-V struct theframe holding the curtain-roller so as to be adjustable as to length or distance between the heads.

A further object of the invention is to form the heads of the roller-carrying frame with enlarged bearingsurfaces to glide smoothly along the window-casing with the least friction and minimum abrasion.

Other objects and advantages of the invention will be brought out and made to appear in the following specification, reference being had to the accompanying drawings, forming a part thereof, the invention being more particularly pointed out in the claims.

Figure l is an inside front elevation of awindow with my improved fixture attached in place, parts being shownin various positions by full and by dotted lines. Fig. 2 is a front elevation of parts at oneV end of the roller-frame,more fully showing the construction. Fig. 3 is a vertical cross-section of the roller-frame, taken on the broken dotted line 3 3 in Fig. l, showing the inner face of the end plate or head. Fig. 4 is a similar crossseetion of parts on the dotted line 4 4 in Fig. 2. Fig. 5 is a side elevation of the device seen as indicated by arrow 5 in Fig .1, further showing the constructionof the parts and the manner of hanging the curtain-roller, parts beingbroken out and other parts shown in various positions by full and` by dotted lines. Fig. 6 is an elevation, partly in longitudinal section, of parts at one end of the curtain-roller, showing interiorV parts.

A in thedrawings is theeasing of the window, a b being, respectively, the upper and th 5o lower sash.

B is a blank upper roller resting in hangers c c, secured to the casing A at thetop, provided with an ordinary ratchet CZ and detent-pawl e. The pendent cord f for turning the roller B is secured to the latter to Wind thereon in the usual manner.

g g are suspending straps or bands for the curtain-roller O, held in a light horizontal frame D beneath the primary upper roller B. These straps or bands take onto offset parts h h of the frame D and pass at the rear side around the roller B on seats t' i, the cord f passing onto the front side of the roller B.

From this description of the parts it will be.

understood that if the cord f be pulled-downward at any time it will .turn the roller B for ward, and so wind up the bands g g and raise the roller-frame D and the curtain-roller O, with its curtain E. It will also be observed that if the cord be slightly pulled in a manner to raise the pawl eoff of the ratchet d, as appears by dotted lines in Fig. 5, and then allowed to slip through the hand the weight of the frame and the lower roller O will turn the roller B backward, the frame, with its roller, thus descending by gravity, as from the position shown by full lines in Fig. l to the position shown by dotted lines, shading another and lower part of the window. The ratchet d is placed on the roller B so the pawl normally prevents the descent of the roller O and the curtain, these being permitted to descend only when the pawl is lifted off of the ratchet by means of the cord, as stated. By

these means the curtain roller O may be brought opposite or4 in front of any part of the window from top to bottom.

The roller-frame D is formed of .two substantially crescent-shaped metal end plates or heads 7c l, connected by horizontal rods m n in a vertical plane, the plates or heads being vertical and occupyingplanes at right angles with the plane of the casing A of the window. The ends of the rods are threaded and pass through openings in the heads, each rod being provided with screw-nuts o 0 outside and inside of each, plate, as shown in Fig. 2, the

nuts being set firmly against the platesto give The roller C is of common construction in curtain-fixtures, being hollow, as shown in Fig. 6, with an axial rod p, provided With a spiral revolving spring 7'. The wooden cylindrical body t of the roller is provided With a ferruled head s, pierced by the rod p, and in which it has bearing, the rod being adapted to turn independent of the body t. The spring r is attached at 011e end to the rod and at the other to the head s to control the relative motions of the parts p and t. The rod is formed with an expanded part u, and the head s is provided with the usual pivoted dogs c o, engaging said part u to act against the spring and keep it normally from turning the rod. The latter is formed with a fiat head w, adapted to occupy a rectangular opening in the plate 7s, Fig. 3, in the usual manner, the roller having an axial journal Figs. 2 and 4, at its opposite end, occupying a corresponding opening in the head Z. Vith the parts thus'constructed the curtain E may be more or less unrolled from the roller C to cover more or less of the window and also moved as a body in vertical directions to cover any particular part of the Window, high orlow. The heads clof the frame are furthermore formed with expanded parts y y, Figs. 2, 3, and il, to meet and glide with minimum friction along the casing A as the roller-frame is moved vertically along the window-casing in the act of shifting the curtain up or down before the window.

lVhat l claim as my invention, and desire to secure by Letters Patent, is-

l. In a device of the character described, a light frame comprising heads formed with extended parts y, rods connecting the said heads, a roller carried in said frame, a curtain mounted on the roller, an upper roller held to turn in ixed bearings at the top of the Windowcasing, means for suspending the lower roller from the upper roller, means for normally preventing the descent of the lower roller, and means for actuating said means to permit of the lowering of the lowermost roller, substantially as and for the purpose specified.

2. In a device of the character described, the combination with the casing, of hangers secured thereto at the top, a blank upper roller resting in said hangers and provided With a ratchet and pawl, a pendent cord for turning said roller and adapted to swin g thereon, a curtain-roller suspended beneath said upper roller, suspending-straps for said curtain-roller, a light horizontal frame carrying said eurtainroller,said straps engaging oisets in said frame and passing to the rear side of the upper roller, Said frame being formed with expanded parts to glide along said casing as the roller-frame is moved vertically, substantially as described.

In witness whereof I have hereunto set my hand, this 20th day of' August, 1902, in the presence of two subscribing Witnesses.

HENRY D. VHIPPLE.
