This invention'.v relates vto improvementsjin window shade apparatus, and has. for its primary object the? sustaining of a. window shade in amanner to insure its correct location relative to ya window at all times by apparatus characterized by its simplicity and inexpensiveness of production. j

A further object is the adaptation ofthe structure possessing the qualifications above recited to windows of varying sizes.-

With these and further object-sin. viewas will in part hereinafter become" apparent and in part be stated, the invention com* Y prises certain novel constructions, combmations and arrangements of parts as :subsequent-ly specified and claimed. f

In the accompanying drawings,- Figure 1 is a view'in front elevation of an apparatus embodying the Vfeatures of 'the presentinvention, Vparts being broken out for the saving of space. Figure 2 is a topplan view thereof. Referring'rto the drawings vby numerals', 1 indicates a substantially U-shaped bracket plate preferablyformed of sheetV metal, either as a stamping or from a strip of Inaterial, the bracket plate being provided-with a vertically upwardly `opening .slotf2 formed transversely in the plate `sl'l'bstantially lmidway of its length and having upstanding legs extending from the portion in `which the slot 2 is formed. Said legsfterminate in offset portions or feet 3, 3, formed Ywith apertures 4, 4 adapted to receive appropriate anchorage means, such as nails or screws..l For purpose of anchorage of said feet to an overhanging portion of a window frame, the legs of the bracket plate 1 may be twisted, as shown in the drawing, to cause the feet 3 to outstand, that yis extend in a'- direction away from each other, but, of course, the presence or absence of such twist is a matter of selection and adaptation ,to

the particular type of window frame.

The bracket plate 1 is thus designed to Vbe anchored to the overhanging portion of the window frame and to depend therefrom in a manner to receive and sustain an engaging pivot from a bracket rod 5. The rod 5 is preferably formed of a strap of metal haviner midway of its length an offset sectiontl digposed to contact with the outer face of the lower portion of the bracket plate 1 and to thus sustain the main'portion of the rod clear of the; slot72. The

5 spaced from the` bracket. A 7 ex;

tends 'laterally Vfromjthe offset portion v6 f through the slot 2 and rests against the bot-- tom thereof, andis provided with an .ap-

propriate head y'8 for 'retaining the bracketl rod 5 in'engagement with the bracket plate 1.y LItlisobvious, of course, that the rod '5.

may `beidetached by merely :being lifted. until' the pivot pin 7 'is moved'vertically upwardly hereinafter stated. `Each terminal portion 9 consists of a strip of appropriate material,

such as sheet metal, stamped or .otherwise formed to shape. Each terminal portion 9` `has a section ylappingithe `respective end 'portion ofthe-prod 5 and slidingly engage` otherwise' suitably anchored portion `v9 at'each end, each being a duplicatefof the other except for the receiving' apertures for the shade roller terminals,.as;

in 7 Jin `practice y ingthe same, La plurality of tabs .10, 10, be-

ngiffomed onach terminal Portion 9 and bemg' bentxiaboutthe respective edge vP01.

tions of the `rod 5 #tov `retain the said rod and. respective send portion 9 `in engagement while allowingfree longitudinal shiftingof;

the respective terminal portion l9 along the engaged portion. of rod 5. Each terminal' `portion 9, beyond the/respective endof the rod 5, eXtendsdownWa-rd and is bent to form a hook-like portion 11 terminating in an upstanding `bracket 12. One of the brackets 12 is formed kmerely `with .an .aperture adapted to receive the usual, extended journal or trunnion 13 of the shade roller 14, while the other bracket 12 is formed with the usual slot for receiving the flat, extended terminal 15 of the shade roller 14, it being understood, of course, that the extended terminal v15 is'of the .usual vconstruction con# `nected to an internal spring of the well known commercial type for elfecting return rotation of the shade roller 14 when it is de sired to roll the shade thereon. The bracket plates 12, 12, may, of course, be otherwise apertured or formedras 'required to receive any particular type of shade roller terminal.

In operation, the bracket plate 1 1s janchored to the over-hanging. portion of the window casing or frame by appropriate eor ' tures 4, and the bracket rod 5 is mounted pivotally on the bracket plate 1. The terminal portions 9 are then adjusted longitudinally with respect to the rod 5, preferably to such location that each terminal portion 9 overlaps the engaged end portion of rod 5 to substantially the same extent asr does the other terminal portion 9 so as to produce an exact balance and cause the coin-A pleted structure to maintain by gravity a' substantially horizontal position While resting on the pivot 7.Y The shade roller 14 with its shade, not illustrated, is then mounted in the bracket plates 12, and the structure is ready for use. It should be noted that if the actuating `spring ofroller 14 (not illustrated) causes that end of roller 14 to be slightly heavier' than the opposite end portion, or if one end portion of the roller 14 with its shade is slightly heavier than the other for any reason, an eilective balance can readily be obtained by an appropriate adjustment of the terminal portions 9. g. The

terminal portion 9 at the heavier end portion of roller 14 is merely adjusted slightly from the pivot 7, and the other terminal portion 9 correspondingly adjusted in a direction away from the pivot 7, but at all times such adjustment, when required, Will be usually only very slight. Yet, the construction is such as to lend itself effectively to a nicety of balance so that a canted position of the parts will not occur. The shade is operated substantially the same as the ordinary shade, except that should a careless operator cause the shade to assume a slightly angular relation to the roller 14, the parts Will adjust themselves by gravity to a balanced position Whereas the bracket rod 5 -Will be slightly out of the horizontal and .supporting parts thereby to assume their Y normal horizontal position.

This application is a division of my parent application, Serial No. 533,795, filed February 3, 1922, Patent No. 1,546,565, July 21, 1925 and covering improvements in Wintol dow shade apparatus. -Three other divisional applications from said parent application are copending herewith, of which two contain broad claims relative to this application, and this application contains claims sufliciently broad to read upon the showing in the third of said other divisional applications.

What is claimed is f 1. In Window shade apparatus, the combination of a U-shaped bracket plate adapted to have its legs anchored to afhorizontal overhanging surface, a flat bracket rod having an ofset intermediate portion contacting withand pivotally engaging the bracket plate, and shade roller sustaining means carried by said bracket rod.f

2. In Window shade apparatus, Vthe combination of a U-shaped bracket plate adapted to have its legs anchored to a horizontal overhanging surface, the plate having a vertical slot opening upwardly intermediate its ends, a flat bracket rod'having an offset poi'- tion contactingv With the bracket plate and pivotally engaging the same through said slot, and shade roller sustaining meansl carried by said bracket rod. l

In testimony whereof I aiiiX my signature.
