This invention relates to a new and improved irture for the'cord of a window shade, the fixture containing a knob Aor pulley'around which theflowerpart of the cordpasses,'and by adjusting whichK-the cord may be stretched when necessary, and always kept in a proper taut state.

This case is secured byscrews or nails, b, to the-side 'of the window frame, and in .the slot or'openingc there'is -tted a slide, B, which is considerably shorter than the slot 01' opening, in order that thezformer may work up and down inthe latter a requisite distance, the sides of the slot or opening serving as'guides .for the slide. To the exteriorcf theslide B there is attached a knob or Ipulley,'C,- around which the lower-part of the shade cord'passes, and th'e inner `side of the slideB is provided with'a rack, c, into which a screw, CX, gears, said screw being on a rod, D, fitted within the case A, and havinga thumb-wheel, E, on its lower endat the outer side ofA the case A.
