0b flea/a I BY J 72 ATTORNEY.

Patented June 17, 1930 Jenn HEALD, or PASADENA, cnmronnm winnowsnnnn Application filed May 27,

This invention has relation to window sun shades and refers particularly to improvements in ventilating roller shades.

The general object of the invention is the provision of a roller shade of simple and inexpensive construction, which is capable of arresting sunlight and at the same time to admit an abundant supply of air. With this object in view my invention consists in the combinations hereinafter fully described and illustrated in the accompanying drawing, of which: v

Fig. 1 illustrates a ventilatingroller shade embodying the invention, 1

Fig. 2 is across sectional end elevation of the structure, and v Fig. 3 shows a modified form of device,

The structure of my invention comprises a shade roller 1 of any well known standard construction, to which two rows of overlapping strips of shade cloth 2, 3 are attached. These strips may all be alike. The strips 3 are first mounted on. the roller in uniform spaced relation, whereupon the strips 2 are fastened on top of the former in similar spaced relation but so that each strip 2 covers a space between two ofthe strips 3. V

A spreader bart is placed between the two rows of strips in close proximity to the roller, and this bar may conveniently be hung on the pivots of the shade roller, substantially as indicated in the drawing, or it may, of course, be mounted on the windowframesupporting the roller, in the proper relation thereto. .The lower ends ofthe strips are fastened to a suitable cross bar 5 in any convenient manner.

The spreader bar 4: and the bottom bar 5are preferably made the samewidth and may be as wide as the roller so as to aiford ample space between the two rows of strips.

The width of the strips in relation to the widtlrof the openings, betweenthe strips should be so proportionedthat no slanting ray of sunlight may pass through the openings of the two rows. As the two rows of strips are shown in Fig. 1 such rays may pass through the space6 and'the space 7, but this is done merely for. the sake of clearness of illustration. In actual practice, where itis'desired to cut out sun rays entirely, the opensae. seal No. 366,244.

ings between all thestrips must be so narrow relative to the width of thestrips that this cannot ha'ppen. 1 The structure of Fig. 3 comprises twoshade rollers 10,11, one mounted directly abovethe other and each carryingone row of strips 12, 13; The rollers and stripsmay all "be alike, the only dilference'between the two being, that the strips on'one rollerare mounted clockwise and on the other anticlockwise, whereby an effect isproducdsimilartothat above described. Inthis case no spreaclerbar is re quired, but as an extra roller with its mountings is needed; this structure is,perhaps, not

as inexpensiveias the one above described. y 'lheadvaiitage of this modified device is that each of the shades maybe operated independent of the other. In case more light is desired, the one may be lowered more than the other. Also that one maybe replaced without disturbing the other.

Because of the many different widths of windows it is common practice to trim the sideedges of the shade cloth to the size desired, leaving such trimmed edges unpro--:

'tected and apt to unravel. WVith my device it is possible to carry strips of standard sizes and, where there is a variation of a few inches in the Width of the shades, to vary the space between the strips slightly. If, for example, a one-yard shadeis required, four six-inch strips may be employed in each .row with three-inch spacing between the strips, and one three-inch space at one end of each row. Should now a thirty four inch shade 1 be required, it is only necessary to reduce each space by one-half inch, all the strips remaining the same.

m OF

It is also possible with my device to use i strips of different colors and ornamentations,

andtherfeby to provide a great number of desirable decorative eifects not obtainable in ordinary shades without incurring great expense.

Iclaim:

v 1. In a sunshade device, tworows of strips of shade cloth, each of which is fastened to a roller of the device at one end and to a 1 apart and so related that the strips of one row cover and overlap the spaces bet-ween. the strips of the other row, and means maintaining one roW spaced apart from the'other row.

2. The combination with a shade roller, of a row of shade cloth strips mounted on said roller and uniformly spaced thereon, a second row of strips mounted on the roller to cover the spaces between the strips of the first row, means mounted'close'to the roller for maintaining the two rows of strips spread apart, and a cross member to which the free ends of the strips are fastened, the strips of the two rows being bent around said mem-f her from opposite sides.

3. The combination With a shade roller, of two rows of shade cloth strips mounted on said roller, the strips of one-row covering and overlapping the spaces between the strips of the other row, a member hung on thepivots of the roller and capable of maintaining the two rows spread apart, and a member to Which the free ends of both rows of strips are fastened from opposite sides.

, 4. In a roller shade, two rows of shade cloth strips forming two barred curtains positioned one behind the other, the strips of'one curtain covering the spaces between the strips of the other curtain, meansonwhich said curtains are Wound for raising andlo wering,

and means maintaining the two curtains spaced apart. 7 I In testimony 'whereof I have hereunto affixed my signature. 7 JOHN HEALD.
