\ "The Schedule referred these Lettersy Patent and making parl: of the same.
i To alliwlwm 'it may concern L I l l f Beit knownthatLr-Onnnnns R. RAND, of Du-y buque, in the county" of Dubuque and` the State of Iowa, `have invented anflmprovement for Locking Device for Window-Cords and I do hereby declare the followingto'be e; full, clear, and exact,description` of the same, reference beingfhad to the accompanying drawing forming partof this specificatiomin which- 'Figure l,"` Sheet'` I, lis an elevationj of`a window,

` 's l `liigure-S, `Sheet 1I, is allongitndinal' section of the' `locking device, andslioiving ,the cord released. l
l Eignre4, Slieet I'I,;is a` longitudinal `section of the llocking device, `vvitl.( ,tl1e` operatingcordsl locked in` r11, y Similar letters indicatelikeparts. I
placeyand t, t t Y i is` anend elevation of the same.
; jM-y invention ,liaszfor lits object to provide an improved device for locking` the operating cords of win'-` j i dow-"sashesand blinds .in position, to hold the sashes r 0r blndseither `rinsed orflowered; and to this end A i `The invention consists f in the construction of the f locking deviceyto behereinafter morejfnlly described;
d', l the. operating cords, ipassing y over pulleys in sill through the` flanges fr. .r
The, ease is divided into two longitudinal compartments by the partition S, each provided -with a grcoved roller, T T',a clamping-lever, U, a lockingpawl, U, andan India-rubber spring, V.
The looking-pawls are vpivoted to thelower edge -of the case, with-"their forward serrated ends immediately beneaththe rollers T, and `theirrear ends resting upon the springs V.
lhepawls U' bear upon the rear ends ofthe levers,
and when thrown into position shown in iig. 4, cause the serrated end of the levers to clamp the operating cords against the roller T, as shown, and when occupying theposition shown in iig. 3, release the 'operating cords, and allow this to move freely upon the rollers 'Il T". v
The Vtension ofthe springs V holds the `serrated ends of the` levers-from contact with the cords and rollersY when the .pawls occupy the position shown in fig. 3. `Having thus described my invention, v l What I claim as new therein, and desire to secure by Letters Patent, is f j The locking device, consisting of the case B, pivoted lever U, rollers T T', pawls UV', and springs V, all arrangedand operating substantially as described, for Y the purpose specied.
