ldclaims.

This invention relates to window shades and more particularly to that class of shades commonly known as Venetian shades.

The object of the invention is to provide a slatted pull shade, the individual slats or panels of which extend vertically of the window and may be convenienty adjusted at any desired angle with respect to each other so as to control the amount of light entering a room between said slats and also the direction of said light rays, while, at the same time, permitting clear visibility in all directions between the individual slats when the shade is in either lowered or partially lowered position.

A further object of the invention is to provide a slatted shade having vertical slats or panels formed of durable flexible material whereby to permit the shade to be attached to and wound upon a standard curtain roller, the lower ends 29 of the slats being pivotally mounted on a transverse end bar so that by rotating or. partially rotating the pivoted ends of the slats, the lower portions of said slats will be twisted to the right or the left and thus present different artistic 25 effects with or without the standard opaque curtain as a background. A further object is to provide the curtain roller with spacing members for guiding the individual slats or panels on said roller when raising so or lowering the shade and also to insure proper and uniform spacing of the several slats.

A further object of the invention is to provide a decorative shade of vertical flexible slats which are constantly held under tension and which may 35 be disposed so as to display opposite surfaces of the slats at the top and bottom of the shade.

- A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efliciency.

The slatted shade forming the subject-matter of the present invention is adapted to be positioned either inside or outside the window jamb in front of the usual opaque pull curtain, and in -Figure 1 of the drawings, the window is indicated .at 5, the pull curtain at 6, and the improved slatted shade at 1. The slatted shade may be made of any durable flexible material, but it is preferred to construct the same of regular pull shade cloth, the opposite faces of which are of contrasting colors so as to give the artistic effects hereinafter referred. to. The device comprises a plurality of individual vertically disposed slats or panels 8, the upper ends of which are secured in any suitable manner to a spring roller 9 mounted in standard brackets ill at the upper end of the window frame, as shown. Slidably mounted on the curtain roller 9 are spacing members II preferably annular in shape and of sumcient size to form guiding partitions or barriers between the individual slats 8 when the latter are wound upon the curtain roller. The terminal spacing members [2 are preferably provided with lateral flanges i3 which are secured to the curtain roller by tacks or similar fastening devices It so as to prevent movement thereof. The spacing members 12 and fianges l3 serve to insure proper and uniform rolling of the slats as they prevent piling up of the slats on each other or overlapping at the sides of the shade when the shade is raised. Secured to the lower end of each slat or panel ii is a reinforcing clip l5 preferably formed of sheet metal and which serves to reinforce the slats and prevent raveling of the lower ends thereof. The clips l5 are substantially V-shape in cross section so as to embrace opposite sides of the slats and the material constituting the lower ends of the slats is preferably rolled or folded to prevent raveling and secured within the clips by pressing or denting the metal to form bar ll having spaced bolts ll extending vertically therethrough with their lower ends threaded for engagement with suitable clamping nuts II. The upper end of each bolt II is bifurcated, at III, to receive the reinforcing clip on'the adjacent slat and to which it is secured by a bolt or rivet 2|. The portions of the bolts l8 passing through the bar I! are devoid of threads so as to permit said bolts to rotate within the bar l1 and thus allow for twisting or angular adjustment of the lower ends oi the slats oi the shade. The slats the space between the slats relatively narrow so that when the shade is pulled down, the slats will form an effective closure for the interior 01'- a room and prevent the entrance of sunlight therein. Inasmuch as the slats l are iiemzible,

slats may be twisted at any angle of inclination with respect to each other so as to control the amount of light entering a room between said slats and the direction of said light rays. For illustration, the slats on one side of the medial longitudinal line of the shade may be adjusted so that they incline towardssaid line and the slats on the other side adjusted at a difierent angle or all of said slats may be adjusted at the same angle, the arrangement of the parts being such that any desired adjustment may be eifected at a moments notice merely by turning or twisting the lower ends of said slats. I

In Figure 3 of the drawings the lower ends of the slats have been given a halt turn so that the space between the lower ends 01' the slats is relatively wide, while the upper ends of the slats remain substantially in contact with each other, the turning of the slats imparting a twisting movement thereto, as will be readily understood.

When the opposite surfaces of the material 0! which the shade is formed are of contrasting colors, very pretty and artistic eilects may be produced by completely rotating the lower ends or the panels, as shown in Figure 4, and thisvefi'ect will be materially enhanced when the opaque pull curtain Ii is in lowered position. However, it is not necessary that the pull curtain be in lowered position as very striking lighting eiiects may be obtained within a room by allowing the light rays to pass between the slats when the latter are adjusted, as illustrated in Figure 4. Many different artistic effects may be obtained by rotating or partially rotating the lower ends of the individual slats and further detail description thereof is deemed unnecessary. Secured to the bar I1 is a coiled spring 22 to which is attached a pull cord 23 to facilitate raising and lowering of the shade. The lower end of the pull cord fastens in a spring clip 2! secured to the window sill so as to hold the slatted shade under tension. It will here be noted that inasmuch as the slats or panels I are secured to the spring roller 8, the slatted shade may be raised and lowered in a manner similar to an ordinary pull shade and turning or tangling of the slats is eflfectually prevented by means of the spacing members II. It will further be noted that the spring roller acts as a tension device for the upper ends oi the slats use the slatted shade, saidshade may be com-' pactly wound upon the'roller 9 by releasing the pull cord from the clip 24 and exerting a slight downward pull on said cord. Conversely, the

slatted shade may be lowered to any desired position of vertical adjustment with respect to the window by again manipulating the pull cord 23 and after adjustment oi the shade has been eiifected, holding the shade in adjusted position by inserting the pullcord in the spring clip. As the winding of the flexible slats on the spring roller is in a direction opposite to that oi the winding of the standard shade or curtain 6, ample space is provided between the parts to permit proper operation or the slatted shade.

It will, of course, be understood that the Venetian shades may be made in diiierent sizes and of any desired material without departing from the spirit of the invention.
