SHADE-ROLLER FIXTURE.

Application filed April 16, 1926. Serial No. 102,531.

desired, the shade being" moved in'one direction by gravity and in the opposite direction `by the unwinding of a cord from a spool, retaining means being associated with the said cord to hold it and the shade in the required adjusted position. The retaining means is operable by pressure to release the cord and is actuated by a spring to automatically grip and hold the cord which passes between cooperating jaws.

`Wliile the Ldrawings illustrate a preferred embodiment of the invention it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits, thereof, reference is to be had to Vthe following description and the drawings hereto attached, in which,

Figure lis an elevational view of a window provided with upper and lower shades, including control means embodying the invention,

Figure 2 is an enlarged sectional view on the line 2 2 of Figure 1, of the retainingmeans for holding the shade roller operating cord in the required adjusted position,

Figure 3 is a sectional view on the line 3--8 of Figure 2, looking in the direction of the arrows,

Figure 4 is a detail perspective view of the cord holding jaw and the cooperating plunger and spring, and

Figure 5 is a detail view in perspective of a modilication adapted for a single shade.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters. c

The numeral 1 designates the framev or Casement, of a window which, in the present instance, has associated therewith an Vupper shade 2 and a lower shade 8. A cord 4 is connected at one end to the reinforced end of the upper shade 2 and passes over a guide pulley 5 at the top of the window frame or'casement 1 and has a weight 6 attached to its lower end, said weight serving to normally raise the shade 2 when the latter is released from the restraining means.

Each of the shade-rollers 7 is provided at one end with a spool or drum 8 and a flange 9 to prevent interference of the shade with the operating cord. The spool 8 may 4form a `part of the shade roller or be separate therefrom and attached thereto in any determinate way. When formed separate from the shade roller, the spool may consist of a casting which is secured to they roller by the flange or head at one end and which is provided at its opposite end vwith a journal 10, for pivotally supporting the rollerv in the accustomed Away. vAn operattion by means of the mechanism shown most clearly in Figure 2.

The retaining means for gripping or holding the operating cord 11 comprises a casing`12 which is closed at one end and open at the other end. The closed end is supplied with an outer flange 13 in which are formed openings to receive screws or fastenings 14, by means of which the device is secured to the window frame or easement. sides of the casing 12 are cut away, as indicated at 15, to receive the projecting ends of jaws 16 and 17, between which the operating i cord 11 is adapted to be gripped.` A plunger 18 lhas a loose fit in the casing 12 and projects through an opening in the outer closed end thereof to admit of pressure being exerted thereon to eifect a release of the cord 11. The jaws 16 and 17 are mounted upon the plunger 18, the jaw 17 being fast thereto and the jaw 16 loose. An open coiljspring 19 mounted Vupon the plunger 18 normally urges the same forwardly whereby to grip the cord 1l between the jaws. The spring 19 is Opposite ving cord 11 is associated with each of the `shade is held in'the'required adjusted posi- 11.Yassociatedwith the lowerishade o lleased said shade automatically lowers-y by .Ay plate 23 closes the outer yend of the casing 12 and is setfin a rabbet and retained'in place by .upsetting the projecting end of the ,ca-sing. Forward movement yof the plunger '18 is limited-by the closed .end ofthe casing 12and when pressurefis exerted upon the :pro-jectingend 'of the' plunger the jaw 17 is "moved rearwardly, thereby `releasing the ,cordsll which are free to move to admit `oi' the desired adjustment of 'the' shades. hen Qthe operating cord 11 associated with the upper -sha'de2' is vreleased said shad'eis raised by theweight 6. rlhe upper `shade 2 vmaybe lowered by vpi'illing upon thelower end ofthe operating cord llass'ociated there- "with V This iinwinds 'the cord from the spool and'wiiids the shade 2 upon' the roller, the

V,projecting end portion of the shade vbeing held extended by the weight 6 and 'cord t in a mannerwell understood. When the cord 'is rere'a-son of its lower. weightedend gravitating. The shade 3 maybe raised by pulling uponthercord 11 associated therewith, where- -'byy said cordy is unwound from the spool v8 andthe shade vwound upon the roller to which'thespool is connected. '1n the event of one vshade only being employed the operating eordcoa'cting therewith is gripped between the jaws`16 and 17, the latter being provided with a single groove V20, as shown iny Figure 5,;and the plunger 18 having a 'slot 21 for the 'cord to pass through. The plunger` and aws shown in Figure 5 will be moi'ui'ted ina case substantially as shown in Figure 2 and the operation is the same as ierein indicated.

Having *thus described the invention, I claim:

`1. A cord vholder `of the character specilied, comprisingv a. casing, a plunger therein, jaws carried by the plunger, the one being fast thereto and the other loose, said jaws projecting` through an opening in the side of the casing, and a Coil spring mounted upon the plunger and exerting a pressure against theiixed jaw' to normally hold the plunger andjaws in forward position.

2. A cord holder of the character vspecified, comprising a casing having openings .in opposite sides, a plunger therein, jaws mounted upon the' plunger'and movable torwardly therewith togrip vthe cord' therebetween,'the outer aw being'loose to vadmit'of the inner jaw moving rearwardly withthe plunger to release the cord, and ja spring wardly. l Y

3. A cord holder of the character specified, comprising a casing having openings in opposite sides, a .plunger "within the casing, fixed and movable-jaws carriedlby the plunger and having opposite endsL projecting through the openings in thesides of the casing anda spring mounted upon the plunger and Vengaging the fixed aw to normally hold the plunger and jaws in forward position.

4c. A cord holdercomprising a vcasing o pen at vits. outer end and slotted in .opposite sides, a plate closing the outer end ofthe casing and the slots in the sides thereof, apair of jaws extending across the casing and through the slots in the sides thereoia 'plunger 'inounted inthe casing and the plate closing the outer end ther'eof"aiid having'thegjaws thereon, and a spring mounted on the plunger and housed within the casing, zand normally urging the 'plunger'and aws outwar-dly.

In testimony whereof I ,my signature.
