while providing for ventilation either below or above .thelshade;

A further object is to provide easy means for changing the range of vertical adjustment of the shade holder, from a part only,

. to the entire vertical length of the window.

The object also is to provide an exceedingly simple device which will be inexpensive to manufacture, easy to install, even by.

inexperienced persons, and one that is durable and not likely to get out of order in use.

I accomplish the above and other objects which will hereinafter appear, by the mech anism illustrated in the accompanying drawing, in which Fig. 1 is a perspective view of my invention operatively applied to a window, and in position at the top of the frame. Fig. 2 is a front elevation of a window on a smaller scale than that ofFig. 1, but showing the entire window with the shade and support in about the same position as shown in Fig. 1, in which the shade is covering the major upper portion of the window. Fig. 3 is a like view of the window showing the shade roller holder below the parting rail of the lower sash, and the shade entirely opposite the lower sash. Figs. 4 and 5 are details showing the construction of the eyelet by which the holding and adjusting cord ofthe shade roller holder is fastened to the-latter and Fig. 6 is a cross section of the roller holder showing the construction of the clamping band thereon.

Like characters of reference indicate like parts in the several views. f

The shade 7 is mounted on a spring-actuated'roller (not shown) havinga round pin'8 at one end of the roller and a flatsided' one 9, at the other; all of usual construction. ertical brackets '10 and 11, to support pins 8 and 9, respectively, are

formed out of strap netal. .1 Thelower ends of said brackets are bent out atright angles to form guiding ears. 12, 12, which are perforated, and through the perforations vertical guide-wires 13, '13, are threaded, in the mannerfshown. Thewires are fastened to the respective screw- eyes 14, 14, screwed into the top 15, of the windowframe, and also to screw- eyes 16, 16, screwed into the sldes of the frame, and the wires, after bei-ng threaded through the perforations of said ears, are drawn taut between their screw-eyes. p

The straps from which the brackets 10 and llare formed are bent at right angles at the tops of the brackets in the opposite direction from that of their respective ears and are continued to form suitable spacermembers 17 and 18, which are joined by a connecting bar 19, made out of the same strap material.

'The spacer- members 17 and 18, are adjustably secured to the connecting bar 19,

by loops 20, 20, formed of strap metal bent 7 around the parts in the manner shown in Fig. 6, with the ends of the strap bent out at right angles to the body-portion forming parallel ears which are drawn together by tightening a nut on a screw-bolt 21, passed This forms a.

through holes in said ears. clamping band by which given adjustments of the spacer-members and connecting bar are held. I

Holes are formed through the spacermembers 17 and 18, preferably as close to their respective brackets as possible in order to secure a direct support, and in these holes the eyelets 22, 23, are fastened. A cord, wire, or other suitable flexible cable 24 has one end fastened to the eyelet 22 It is then threaded through the screw-eye 14 and carried thence across and through the screw- .eye 14 from which a length sufficient to come within'easy reach of a person desiring to raise and lower the shade, and for fastening same to a suitable bracket 25, depends from the screw-eye 14'. A second cable 26 is fastened to the eyelet 23, and is passed thence through the screw-eye 14 from which The ends, of the two depending cable lengths may be tied together if desired, but at any rate, they are manipulated together to raise andlower my roller supporting device with roller and shade attached. The latterjparts are in; fact suspended from alength equal to that of cable 24 depends. V

screw- eyes 14,14 by cables 24 and 26; their weight will move them to the, bottom of the window or as far as'the" guide wires 13, 13,

and lower screw-eyes l6, 16,will let; them go, when the cables are released, and any" desired position is retained by fastening the cables to' bra'ck'et25. The shade is rolled upon the roller and .u-nrolledctherefrom to the desired length in the usual manner, my

invention having only to do with the verti- 'cal adjustment of the roller itself.

Vhile Iha-ve described the best emb'odimentofmy invention now known to me it is obvious thatmany minor changes may be made and I. therefore do not desire to be limited any more than isrequired by the jappendedwlaimb 7 In awindow-shade roller holder, a pair of brackets formed out of strap metal in a separate piece foweachbracket whichis bent outwardly at the lower ends of the brackets to fonnguide-ears, said ears being per- -forat,ed,;and said strap pieces being bent inwardlyiat the upper ends of the brackets to form spacer-.niembers, a connecting bar "lap ping Tth'e" ends of said spacer-members,

, clamping loops binding the lapped ends togather, a pair of screw-eyes attached to the window frame one above each bracket, a pair of screw-eyes attached each to a'slde of the window frame at the lower limit of travel of the shade-roller holder, guide wires re- 7 to the other end of the holder and passing up and through the nearest screw-eye'over that end and "then across'and'through the last-named-screw-eye, and means for making the dependingen'ds of the two cables fast. 7

Signed at lndianapolis, Indiana, thisthe 25 day of March, 1921.
