This invention relates to an improved winmay readily be driven intowoodwork to se- (low-shade fixture and'has for some of its curelyretain the guide-men'iber in place withobjects to provide a structure that may be out the aidof additional fastenings. attached to a window-frame without the Between the two guide-flanges 10, and also use of screws or nails; which maybe readily extending longitudinally, the guide-member adjusted to accommodate shade-rollers of is provided with two parallel but spaced varying lengths;.whose bracket-member ma slits 17 while the metal of said member bebe used at either the right or left end of the tween said slits is pressed outwardly to form roller and to provide a structure of-sheeta spring leaf 18 andvthis leaf midway bemetal that may be produced at low cost. t-we'enits ends has an outward bump or pro lVith these and other objects in view, the 'jection 19, as clearlyshown in Fl 's. 24 and invention is illustrated in the accompany- Softhe drawing.

These recesses- Fig. 9. shows the same in plan or top view. 24, are arranged in a row so as to be in aline- Referring to the drawing the numeral 9 ment, with the ingle projection 19, 011 the designates theguide-member whichis formed s ring leaf 18 of th guide-member beneath from a sheet-metal plate and has turned-over th d th b k t plat i ov d in longitudinal guide-flanges 10, along its opp the guide-plate the spring leaf 18 will yield site sides and down-turned opposite ends 11. as th projection 19 rubs against the under These opposite down-turned ends are corruid f th ba lat o that the aid pr0- gated in a direction at right-angles to the j ti ill S i t th Successive d outer bearing face 12 of the member, and the i as th base-plate i moved lower end of each corrugation 13, is provided Ob iously th t i of th proje tion with a notch 14. 9, in any one of the depressions 24, will lock The lower edge of these corrugated ends 11, the two plates together and the spring leaf has a series of spaced inward bevels 15, on 18 will at the same time press the bracketthe outer side while at the inner side, and al-' plate 22 outwardly against the guide-flanges ternating with the inward-bevels said lower 10 so as to keep the projection 19 entered in r edge also has a series of'outward bevels 16; the depression 24. These alternating bevels 15+16 at the The right-angleend 23 of the bracket-memlower notched edge ofthe ends 11, produces ber 20, extends outwardly from the base-plate;

a series of wedge-like cutting edges which 22 andpreferablyhas a back-turned end26 1 10 7 of base plate 22, as

which lies in parallel relation to the end 23 but is s aced therefrom, as shown in Fig. 6, of tlie rawing.

The end portion 23 of this bracket-member has an outwardl -pressed boss 27 with a squared slot 28 at t e center thereof which slot extends outwardly through the boss to one edge 29 of the bracket-member so as to form a socket for the squared end 30 of the roller shaft. The back-turned end 26 of this same bracket member also has a boss 31 and this latter boss is provided with a sqluared slot 32 which opensat the opposite e ge 33 of the bracket-member. a

It will thus be understood that the two slots 28 and 31 open at opposite edges of the bracket-mem er and that when the end 26 is folded at the side of the end 23 these two slots will be located in the same vertical plane so that if the bracket-member should be reversed in the guide-member one or the'other of the squared sockets 28 or 32 may be utilized to engage the squared end of the roller shaft.

This capability of reversal of the bracketmember in the guide-member materially increases the range of adjustment and enables a very wide shade or a narrow shade to be used without disturbing the fixed guide-memher.

For the purpose of ri 'dity and stifiness, I provide the bracket en s 23-26 with a cen tral stiffening rib 34.

The bracket-member 21, has the same form has the same arrangement of bottom recesses 24 andoutward pro1ections 25,-the only difference' being that s in the outwardly-extend ing arm 35 said end has a complete circular boss 36 with a central perforation 37 to receive the pin ,38on the end of the roller.

Obviously, this bracket-member f 21 may also be reversed end for end in the guide member to give a greater ran e of ad1ustment.

A stiffening rib 39 is a arm 35 of the bracket-member for reenforcin the same.

oth bracket- members 20 and 21 are provided with notches 40 at the base of the arms or ends 23--35 and adjacent to the base plate 22, in order that the arm may clear the guidelugs 10 on the guideanember.

The operation is believed to be obvious without further explanation thereof. 7

Having described my invention, I claim z-- 1. In a window-she tion with a guide-member having out-turned horizontal top and bottom guide-flanges and backturned opposite ends each back-turned end of the guide-member being provided with sharpened edges for entering woodwork at right angles to the out-er face of the guidemember and between said ends the guidemember having a spring-leaf extending parallel with and projecting outwardly between the horizontal top and bottom guide-flanges, of a bracket-member slidably engaging the flanges of the guide member and itself engaged bythe said spring leaf.

2. In a window-shade fixture the combination with a guide-member having inturned guide-flanges along its oppositeedges and between said flanges said member being provided with a longitudinally-extending spring-leaf which projects outwardly, of a bracket-member slidable in the guide-memher between said inturned guide-fianges over the outer side of the spring leaf and means coacting between the outwardly-projecting spring leaf and the bracket-member to lock the latter against longitudinal movement between the guide-flanges.

In testimony whereof I 'affix my signature.
