To all whom t may concern: e
Be it known that I, Jonson DUNLOP, a citizen of the United States, andresident of Floral Park, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Window- Shades, of which the following is a specication. l l
This invention relates to window shades," and my improvements refer particularly to the novel construction and arrangement of a window shade relativelyto the window it serves whereby either orboth the lower and upper portions `of the window maybe ein` posed or obscured, to anydesired degree.`
Briefly expressed, my invention comprises the employment of an ordinary spring roller having attached thereto a shade longerthan the length of `the window. This spring roller is revolubly mounted in bearings lo-` cated at the window sides about midway the length of the window, and a plain roller is engaged with the shade above the spring roller, so that the shade passes from the spring roller, up over` the plain roller, and -thence downwardly, below thespring roller, to cover the lower portion of the window. The plain roller is mounted in bearings which are slidable upon fixed guides located at the sides of the window, and slidable pnl` ley means are provided whereby cords engaged with said plain roller may draw it upwardly, against the tension of the spring roller, for purposes of covering more or less the upper portion of the window. e, e
The lower end of the shade has ineans which frictionally engage the guides to hold the shade in an adjusted position, these frictional means being releasable to permitthe shade to be drawn downwardly against the tension of the spring roller, or to allow said shade to draw up under said spring tension.
Other features and advantages of my said invention will hereinafter appear. ln the drawing: y
Figure `1 is a view, from the interior, of a window equipped with my improved shade; Fig. 2 is ai side view thereof, on an enlarged scale, and
Fig. 3 is a further enlarged detailed View ofa lower corner frame and shade. e y y My invention comprises the use of an ordinary spring `roller l, having attached thereto, in the usual manner, a shade 2. The spring roller 1, instead of being mounted at the upper end of the window, as is usual, is mounted in `brackets or bearingsgw-S, whiehinay be secured about centrally of the window length or` height, respectively at the opposite sides of the window frame 4:. Rigidly mounted at Jthe respective sides of the window `frame are guide rods 5,a`s by the upper"` and lower brackets 6, and a plain roller 7, revoluble inhangers 8, 8a, is by said hangers loosely engaged with the rods, and slidable vertically thereon. `The roller 7, which, islocated above the roller 1, is engaged under the shade" 2, whichY latter wraps` over saidroller 7 and extendsldown `wardjly,"preferably behind the roller 1, to a pointbelowsaid roller l, where said shade is provided with `a lower stiffened terminal portion." rlhe stiifening may comprise a board 9 suitably secured to the lower end of the shade. e .The hangers at oneside of the window is engaged witha cord l0 that passes over an upper pulley 11, said cord extending from said pulley, across the top of `the window, and over a pulley `12l`at the opposite upper side of the window, said cord 10 thence eX- tending downwardly to a lower sheave engaging` device 13.
The pulley 12 is a twin pulley, to aecom-` modate in onegroovethe cord 10, and in the other groove a second cord 11i, ythat branches from cord"l0,.and connects with thehanger 8% Hence the upward fold of the shade may, `through the medium of roller 7 and `cords 10, 14:, 'be drawn upwardly to cover. the upper portion ofthe window, or a portion of the window part thereof,.fro1n the center up, against the roller 1, to thus expose the entire lower half of the window, or which may be drawn by hand, against the tension of the spring roller, down to any desired lower position, to cover either a part or the whole of the lower half of the window.
,Anchorage means are necessary for the lower shade portion, to hold it against displacement when the upper portion is being raised by the roller 7 Therefore I provide frictional devices which may be in the form of L-shaped plates 15, secured at the opposite ends of stiffening vmember 9, and having vertical slots 16, to receive, respectively, the guide` rods 5. Under tension of the spring roller these slots 16, at their rear, upper, and forwardouter edges, bind with frictional purchase against the guide rods, and thus retain the shade in a desired set position. But, by canting forwardly the plates 15, as through the medium of a lug or handle 17, carried .by .the stif:l terminaly portion of the shade, this frictional binding engage-V ment can be released, so that the plates 15, then held with their sl-otsl free -upon the guide rods, may with the shade be moved up or down.
`-Hence, the upperv andv lower portions of the shade are adjustable independently of each other, but it isa condition of the operation of the upper portion thatl the'A lower portionbe anchored. The cord 10, which operatesthe upper shade portion, freely engages the sheave 13, which latter. is journaled in a` bracket 18; and said cord may be frictionally caught between the sheave and bracket to thus restrain the said upper shade portion. against the winding up action -of the spring rollen-.said oord being released when it is desired to opcrate` said upper shade portion.
A spring cushion isiprovided, as in the form of the helical springs 19, 19, mounted on the guide rods 5, just above the position occupied by the spring roller 1, said springs 19, 19, being adapted to receive the impact of the hangers 8, 8a, in case the cord 1() should be let loose against the shade winding action of the spring roller, in which event thehangers and roller 7 would be retracted suddenly toward roller 1. Variations may be resorted to within the spirit and scope of my said invention, and parts thereofl used without others.
1. An improved window shade having a spring roller, bearings therefor Xedintermediate the top and' bottom of the window i served, a shade carried by said'roller, and
means for moving an upper portion of saidshade above said rollen-while permitting the lower portion of said shade to be moved below saidroller, whereby the upper and lower portions of the window may independently be partially or wholly obscured or exposed.
2. In an improved window shade, in combination, a spring roller carrying a shade, means for mounting said roller upon a window frame, means for anchoring the lower end of said shade, and means for moving upper portions only of said shade relatively to said roller to cover `or expose the window above the location of said roller.
3. In an improved window shade, in combination, a spring roller, carrying a shade, a window frame, means for mounting said roller in a fixed position intermediate the top and bottom of the window frame, vertical guide means at the sides of the said window frame, a plain roller slidably engaged with said guide means and located above said spring roller, whereby the shade may pass over said plain roller and depend below said spring roller, means for anchoring said shade at its lower end, and means for moving said plain roller vertically with the upper portion of said shade.
f 4. In an improved window shade, in combination, a spring roller, a shade upon said roller having a stiff, terminal portion, means for moving upper portions of said shade relatively to said roller, iiXed means for mounting said roller upon a window frame, intermediate the top and bottom thereof, guide means l at the sides of the window frame, and releasable means of frictional engagement between said terminal portion and guide means.
5. In an-improved window shade, in combination, a spring roller, a shade upon said roller having a stiff, terminal portion, means for moving upper portions of said shade relatively to said roller, fixed means for mounting said roller upon a window frame, intermediate the top and bottom thereof, guide rods for location at opposite sides of said window frame, and slotted members on said terminal portion having loose, canted engagement with said guide rods, the tension of said spring roller, in retracting said shade, thereby tending to straighten said terminal portion, and causing said slotted members to have frictional purchase upon said guide rods.
6. In an improved window shade, in combination, .a spring roller carrying a shade` a window frame, means for anchoring the lower end of said shade, vertical guide means at the sides of said window frame, a plain roller slidably engaged with said guide means, and located above said spring roller, whereby the shade may pass over said plain roller'and depend below said spring roller, cord and pulley means to actuate said plain roller to move the upper portion of the shade against the tension of the spring roller, and
