To all whom it may concern,.-

Be it known that I. JAMES A. LYONS, a citizen of the United States, residing at Knoxvillein the county of Knox and State of Tennessee, have invented a new and useful Improvement in Curtain-Fixtures, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to curtain-fixtures, and particularly to that class of window-curtain fixtures in which provision is made for the vertical adjustment of a horizontal spring-roller upon which the curtain or shade is rolled, the object being tosecure light and ventilation from abovethe curtain when desired.

The present invention is an improvement 'n upon the invention whichis the subject-matter of Letterslatent of the United States Nos.

739.889 and 7 39,890, granted to me Septemloer 29, 1903.

In the accompanying drawings', Figure 1 is a front elevation of a fixture embodying my improvement. Fig. 2 is an end elevation of the construction shown in Fig. l'. Fig. 3 is a front elevation of one of the upper supporting devices. Fig. L is a side elevation of the structure shown in Fig. 3 looking toward the right. Fig. 5 is a side elevation of the structure shown in Fig. 3 looking toward the left. Fig. 6 is aperspective'view of the cord-supporting stirrup shown in Figs. 3, 4, and 5. Fig.

7 is a front elevation of the right-hand portion of the roller-supporting yoke. Fig. 8 is' an end elevation of the structure shown in Fig. 7. Fig. 9 is a vertical cross-section on the line 9 9 of Fig. 7 looking in the direction of the arrow. Fig. 10 is a section on the line l0 10 of Fig. 7. Fig.- l1 is a plan of the structureshown by Fig. 7. 12 is an enlarged front elevation of a fastening device. Fig.. 13 is a s1m1lar side elevation. 1

cords are joined together by knotting or in any other suitable manner. The cable 10 thus formed is extended downward along the window-casing and adjustably secured to a suitable fastening device 11. Obviously the cable l0 may be a single cord. From this description it will be understood that by drawing said cable downward the supporting-cords 5 and 6 will be drawn upward and that such upward movement involves the upward movement of the yoke 3 and the' roller 2.

The cords 5 .and 6 and the cable 10 may be of any suitable form, and in place of what is usually termed-cord braid, wire, or chain may be used. The fastening device l1 may be of any suitable formadapted to engage the cable 10 at such points as may be desired, and said fastening device may be secured tothe windowframe in any suitable manner. The form shown is a tube, (preferably flaring at each end,) through which the cable passes. The lower portion of said tube `is provided with a V-shape notch llc, into which the cable l0 may be drawn. The knots 10 on said oable facilitate the engagement of the cablein said notch. Said fastening device is shown in enlarged detail in Figs. l2 and 13.

The supports 7and 8 may be of any desired form adapted to support and guide the cords In the drawings 1 have shown pre- 5 and 6. ferred forms, consisting, respectively, of an ordinary roller-

bracket

7a and 8 and a onepiece wire stirrup 7b and 8l. the bracket 7 L being appliedto the upper portion of a windowl f ed outof its stationary brackets and moved down into myyoke and the Stirrups applied tosaid stationary brackets without changing the latter and without attaching any other mechanism to the upper portion of the window-casing, said wire stirrups being in themthe former is adapted for the left-hand side and the latter for the right-hand side of' the window; but making said stirrups right and left is only a matter of preference and not essential. Adetailed description of the stirrup 8b is suiicient for both. Atits middle it has the downward U-shape fold 8C to be applied to the left-hand side of the adjacent bracket. The forward arm is bent laterally toward the left and downward to form a hook 8d, adapted to extend through the bearing B of the adjacent bracket. The rear arm of said U is bent laterally and downward, so as to extend across the rear portion of said bracket` and thence downward to form an inverted-U- shape hook or fold 8e, embracing the two sides of the upper portion of said bracket. Then made in the form thus far described, said stirrup is complete for the supporting and guiding of the cords 5 and 6. To also adapt said stirrup to support the upper end of the adjacent guid e-cord, the portion ofthe wire forming the hook 8e is extended laterally and then upward to form a U-shape hook 8f. In the stirrup 7b the lateral direction of the hooks 7, 70, and 7f,(corresponding, respectively, to the

hooks

8d, 8e, and 8f) is toward the right.

The brackets 4 are integral with a foot 4, and said foot is integral with a sleeve 4h, surroundingthe yoke-bar 3a. Said sleeve may be secured at any position along' the length of theyoke-bar by means of a nail or screw or similar device 4, extending through the sleeve 4b into said bar, preferably from above.

The yoke is provided at each end with a suitable passage for the lower ends of the su pporting-cords. Such a passage may be conveniently formed by forming in the yoke-bar 3*, preferably in its lower face, a channel 3b, where the sleeve 4b surrounds said bar, and the adjacent cord 5 or 6 extends downward across the end of the yoke-bar and thence laterally through said channel and sleeve. Said channel is preferably formed along the entire length of the yoke-bar in order that the brackets 4 may be moved horizontally upon -said bar to tit any length et" shaderoller, the portion of said bar extending beyond the sleeve 41 being then cut otl". This construction is of practical` value, because it adapts a yoke-bar of maximum length to be applied to windows of any width. 4

The cords 5 and 6 after passing through the sleeve 4b., as already described, may be secured in any suitable manner so as to suspend the yoke horizontally.- I have found it desirable to provide an adjustable attachment for the lower ends of said cords in order that lthe yoke may be readjusted at any time when one end becomes lowered by the stretching ot' one of said cords 5 and 6 or when itis desired to raise or lower the entire yoke relative to said cords, as when the knots 10 do not engage at the right elevation to bring the shade to the exactdesired loweror upper limit. ln the drawings, 11" is a clamp ln'n'izontally adjustable upon the yoke-bar, and the end ol the cord is attached to said clamp. Said clamp may be constructed in various forms; but for the sake of economy I prefer to make it ot' a single piece of wire, as shown by the drawings. rlhe main portion of said clamp is U form and embraces the bottom and sides of the yoke-bar, while the upper end ol each uprig'ht arm of the U is bent laterally away from the adjacentcord to iorm an arm 1 1, bea ring upon the upper face of the yoke-bar. 'l`he adjacent supporting-cord is tied to the lower portion of said clamp. The construction described adapts said clamp to engage or grip said bar when strain is put upon said cord. The upper point oi engagement is between the ends of the arms 11l and the upper tace of the yoke-bar, and in order to augment such engagement said ends are preferably made angular or pointed. \Vhen the clamp is engaged by the hand and inclined, as shown in the drawings, it may be readily moved in either direction on said bar. Having these clamps as a part oi the apparatus, it is unnecessary to take pains to have the two supporting-cords 5 and 6 precisely equal in length from the

supports

7 and 8 downward or to have said supports precisely in the same horizontal line. Said supports may be placed only apj'iroximately in the same horizontal line and said cords may be only approximately even in length when they are applied to the yoke, and then they may be accurately adjusted by means oi said clamps alter the shade is in place.

A guide-cord 12 is placed at each side oi the window-casing, the upper end ol each cord being secured to the adjacent hook 7f or 8f and the lower end being secured to any suitable stationary device attached to the windowcasing. The drawings show a stirrup 123 secured to the lower end of each ol said cords and said stirrups extending around a nail 14, which 4extends horizontally outw ard from the window-casing. Said stirrup is preferably formed of a single piece et' wire bent into U form, with the upper portion nearly closed and the upper ends ofthe wire bent laterally -in the plane of the stirrup to lorm hooks 13" to be`engaged by a loop l2, formed on the said guide-cord. As ameans for securing the yoke Bslidably to said guide-cords, wire loops 15 are applied to the sleeve 4", as shown in detail by Figs. 7, 8, 10, and 11. Said guide consists of a single piece of' wire folded upon itself and around the rear, bottom, and a portion of the front ot' said sleeve and extending through apertures 4ll in the loot 4", by which construction said guide is eilecti rely secured to said yoke. The upper end olt said guide is preferably curved rearward, as clearly The guide-cord extends shown by Fig. 8.

'shade-roller.

throu'gh said loop and behind rsaid sleeve'and foot. rIhe yoke is free to move up and down upon said cords` but is held by them against lateral movement. While sliding up and down each foot 4 bears only against the adjacent guide-cord and the loop 15 does not make contact with the window -casing, be-

cause the weight of the shade and roller tilt the upper portion of the yoke outward away from the window, so that said guide-loop clears the window-casing.

The importance of the several portions of my present invention consists in their simplicity and economy in manufacture. The

stirrups

7 and 8 can be manufactured at very small cost and with simple tools or machines, and they make possible the suspension of the shiftableshade-roller from the ordinary stationary brackets, as above indicated. A maximum length of yoke-bar having the channel 3b may be readily fitted to any length of The clamps 11b are made of wire and are of a form suited to economical manufacture, and the form of said clam ps is such as to permit the easy application of the supporting-cords. This may be accomplished by merely looping the supportingcord through the clamp, as shown by Figs. 7 and 9, and the stirrups 7 and 8a are adapted for the-attachment of the upper end of the guidecords after said ends have been tied to form an ordinary loop 12b, and the stirrups 14: are of such form as to adapt them to be secured to the lower end of the guide-cord after Ythe latter has been tied to form a loop 12, Additional tension may at any time be given to either of said guide-cords by giving its loop 12 additional turns around the hooks 13a.
