of which hangs down far enough to be Within easy reach of any one desiring to raise or lower the curtain roller. controlling cable is wound upon the supporting roller in the opposite direction from the supporting cables so that when the supporting cables are paid 'out the controlling cable is -Wonnd up, and vice versa. It Will thus be curtain. roller may be held in any position to which it may have been adjusted by fastening qthejfree end of the controlling cable to a stationary support; as, for example, by Wrapping it stud o secured to the cass ing. Then it is desired to lower the shade roller' the' controlling` cable is unfastened and ispermtted to b c Wound slowly uponl the supporting roller as the Weight of the curtain roller causes the supporting roller to 'be rotated1v Similarly, when it is desired to vraise the curtain roller., a pull-is exerted upon tie controlling cable and, as it is unwound 'frmn the supporting roller, the latter is rotated in a direction to Wind up the suspending cables. i f

It is sometimes"preferable to have a more secure lockingmeans than that afforded by fastening theloiver end of the controlling cable antlfthcrefore I have" associated with the-supporting roller `a paivl and ratchet devce' \vlii ch normally prevents the support` ing roller from turning in 'the direction ivhiclipermits-,the curtain roller to descend. This may conveniently be'accomplished by with toothed flanges lJ which constitute ratchet' ivheels, and mounting upon the reasing p aWl Q-Which ith the teeth. In the :rrrangemontv shown the pau-l lis made U- shaped, the yoke g drinn M from end to'end. Iso shapethe p aivl that the yoke voverlies the controlling cablejnst after itleaves the drum so that by pulling the controlling cableoutwardly it will engage with the pavvl and lift it clear of the ratchet teeth. Normally, therefore, the supporting roller is locked by th'ef'pawl. When it is desired to raise or lower the enrtain'roller', the paWl ,is released in the manner described and the supporting Vrol-ler then vrotated by pulling upon theV controlling cable. or is permitted to be turned backwardundcr the Weight of the the .controlling cable One of the drumson may be made adjustr'ollers may be obtained when the parts are `first placed in posi-tionand may thereafter l )en 1aintai1 ied in case one of the suspending cables stretches more than the other. In vtl held more upon the supporting roller one or set screws d. By loosening the same the hook from jumping "epd ofthe cable F to the upper end `of the `posite end of the curtain extending across the which Ithe suspend 1cv arrangementshown, the vdrum I) is lts movements up and down the Window;

l will be held firmly in its adjusted positions;

and will operate freely both in its bodily verticaLmovements an in its rotary movements' even though the casing. may be un- -trne 'or Warped so as to bring the-tracks out of para] lismg Without permitting the roller to tal f'in case one end should become unfastened and Without permitting any of the moving parts to come incontact with the Woodwork so as to deface the same. To this end I connect one end of -t-he curtain roller to the slide K in'- such a manner that it is locked thereto and is held against 'axial movements. This may conveniently be accomplished-in the manner disclosed in my prior application, Serial No* 544,819,1iled February. 19, 1910,- the slide K having a slot l: int-o which extends a hook l on' the adjacent. end ofthe roller,

and there being a dog 7c pivoted to the slide above the hook in a' position to prevent l out of. place. By connecting the lower dog, the dog is always held in its locking position by the Weight of the curtain roller and in a movable bearmg member which is free to shift its positionaxially of the roller from and towardthe for any variation in the distance between the tracks. I have-illustrated the movable bearing member as being in the formof va leaf R Which-lies ybetween the slide I and the adjacent end .of the curtain roller and is hinged at its upper end to the slide .at-r so as to be free to swing about -a horizontal axis extending at right angles to the axis of the curtain roller.v Near its free end the mem-berR is provided with a key-hole slot S which isfadapted to1'eceive a headed curtain. The op-' roller is supported 100 slide I so-as to compensate journal T projecting fromthe adjacentend ofthe curtain roller. The member T may conveniently take the form. ofa headed screw Whose hea-d t will lpassthrough the large portion s of the slot but will not pass f through the narrow yportion s. The curtain roller is mounted at this end by slipping the member T through -the enlarged portion of the slot in the supportingv member'.

and thenI letting .the roller drop untilv the journal member rests. in the lower end-,of the slotas indicated .in Figs. 2v `and 3. The `neck of the'keyeh'ole slotmaybe arranged diagonallyof the member R andtangenti-al to theenlargement sso that it would bef' dillicult for the dentally detached.

When' the curtain roller lis shifted up 4or journal to become 4.accidown it-,followsthe configuration 'of the track H because it is interlockedtherewith. Should either track be out ,of true so as to lbring the two tracks out of parallelism,rr the end of the roller adjacent to the track Gr` will move toward and recedel from this track as the roller is carried up and down; the member R` swinging about its hinge so as to vary thev angle which it makes with the slide upon-which it is supported and affording a proper support for the adjacent end of the roller so that the roller may j turn freely in raising or lowering the curthe Woodwork and all of the movable supporting parts lie between the end of` the roller and the track so that as the end of the roller moves toward the trackI it is Iprevented from coming in contact with the Woodi Y work and therefore cannot scratch or othersu "ortinblih'e same. I l5.11111' c `mb nation, a le Wise lmar the woodwork. It Will thus be seen that the curtain roller is supported firmly and yetlexibly so that it doe not become cramped or' locked against move# ment in case the windoiv casing has become `Warped so as to make the tracksu'nevi` `n.

It .will also be seen that in case the oppo te end of the roller becomes disengaged from its supporting meana'thelen'd mounted upon the swinging plate or hanger will prevent the roller from lfallin down entirelyv because Athe journal on t e head will' engage with the rear side of the hanger and will bring the' roller to rest after the free end has dropped a predetermined distance, j
