T0 aZZ whom it may concern:

Be it known that I, JAMES A. LYONS, a citizen of the United States, residing at Fountain City, in 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.

Myinvention relates to curtain-fixtures,and particularly to thatclass of window-curtain fixtures in which provision is made for the vertical adjustment of a horizontal springroller upon which the curtain or shade is rolled, the object being to secure light and ventilation from above the curtain when desired.

In the accompanying drawings, Figure 1 is a front elevation of a fixture embodying my improvement. Fig. 2 is an endelevation of the construction shown in Fig. 1. Figs. 3, 4, 5, and 6 are detail views of one end of the yoke which supports the curtain-roller, Fig.

6 being a section on the line 6 6 of Fig. 3.

Figs. 7 and 8 are sectional elevations of the pulleys over which pass the cords by which the curtain-roller and yoke are suspended. Fig. 9 illustrates a sheet-metal blank from which the brackets for the yoke are made.

Referring to said drawings, 1 is the window- 2 is the curtain-roller. 3 is a yokebar. 4 4 are brackets applied to the ends of the yoke-bar and having bearings for supporting the shade-roller in the usual manner,

said brackets and yoke-bar together forming a yoke. 5 and 6 are cordsextending from the yoke-bar, the cord 6 passing over the pulley 7 and thence over the pulley 8 and the cord 5 passing over the pulley 8. Said two cords are joined at 9, and from 9 a cord 10 passes downward along the window-casing and is adjustably secured in a suitable fastening device 11. From this description it will be un-' 'derstood that by drawing said cord 10 downward the cords 5 and 6 will be drawn upward and that the upward movement of the cords 5 and 6 involves the upward movement of the yoke-bar 3 and the roller 2. The cords 5, 6,

and 10 may be of any suitable form, and, in place of what is usuallytermed cord, braid, wire, or chain may be used. -The fastening device 11 maybe of any suitable form adapted to engage the cord 10 at such points as may which it should go.

be desired. It may be secured to the win (low-frame in any suitable manner. The form shown is a tube, (preferably flaring at each end,) through which the cord passes. The lower portion of said tube is provided with a V-shaped notch, into which the cord 10 may be drawn. To facilitate the engagement in said notch, the cord 10 may be provided with knots 10.

The pulley 8 may be of any desired form. The'drawings show said pulley seated in a housing composed of the base 8 and the upper and lower webs S", a lateral web 8, and front wall 8. The purpose of the lateral web 8 is to limit the downward movement of the curtain when the cord 10 becomes accidentally released or when the person operating the curtain inadvertently allows the cord 10 to move upward farther than is required to lower the curtain to the lowest point to It will be observed that the cords 5 and 6 pass on opposite sides of 7 said web. Hence they cannot descend farther 7 5 when the point of junction has been brought against said web. The upper and lower portions of the pulley-housing are symmetrical. This construction permits the use of the same housing. at either upper corner of the window. By inverting the pulley 8 it be- By making the housings in this form the cord -10 may be located at either side of the window. If said cord were to be placed at the right-hand side of the window, the cords 5 and 6 would exchange places with each other. p j

Obviously, so far as other portions of my improvements are concerned; anysuitable eyes or staples might be substituted for the I pulleys illustrated by the drawings.

The bracket 4 is composed'of the foot 4*,

The sleeve 4 surrounds the end of the yoke-bar 3, and the foot extends vertically downward and has 5 its lower end bent slightly forward. The upright 4 extends outward across the adjacent end of the roller 2 and forms a bearing for said roller. A wire is folded upon itself,

as shown in Fig. 6, to form the eye 4 and the guard 4 A portion of said eye and said guard lies within the sleeve 4 above the upper edge of the yoke-bar 3 This construction is used as a convenient. method ofproviding an eye at the end of the yoke and a guard in frontof said sleeve, said eye being for the passage of the cord 10 or the cord 12 and said guard being for the passage of the cord 5 or 6. The sleeve t" binds said Wire immovably. The cords 5 and 6 may be attached to the yoke-bar in any suitable manner. For the purpose of rendering said yoke and roller more stable I prefer to attach the cord 5 to the upright 4 near the bearing of the curtain-roller in order that when the curtain is being drawn downward by turning said roller there will be little tendency to tilt the yoke and roller. In the drawings I show said attachment formed in the aperture f. The guard 4 is a further means for preventing the backward tilting of the yoke. To prevent wear by contact with the guard, the portion of the cord from the upright 4 through the guard may be wire. In the drawings, 10" is such a wire. This has at one end a hook extending through the aperture 4 and at the other end an eye 10 for the attachment of the main portion of the cord. Said wire is preferably bent adjacent to said eye sufficient to bring the wire forming said eye into a plane to which the cord is perpendicular in order that the main portion of the cord may be extended from above through said eye and knotted beneath the latter. When made in this form, the entire knot forms a bearing against the wire surrounding said eye and during the operation of the fixture there is but slight, if any, friction or movement of said knot upon the wire surrounding the eye. Hence there is but slight'tendency to wear or cut the fiber of the cord. I have found this construction much more durable than a construction involving the resting of the body of the cord across the wire. If the eye 10 were transverse to the direction of the cord, the engagement between the main portion of the cord and the wire of the eye would be at only one side of the cord and would, as I have learned by tests, be readily out.

The sole function of the cord 12 is to serve as a stay for the yoke and roller. At its lower end said cord may be secured by a fastening device 11, preferably a duplicate of the fastening device at the opposite side of the window. At its upper end it may be fastened in any suitable manner. The drawings show a wire arm 13, having an eye 13 at one end and a hook 13 at the other end of proper form to extend around the web 8 of the pulley-housing, whereby said arm is held firmly in the horizontal position, as shown in Figs. 1 and 7. When said arm is made in this form, it is adapted to be applied to either pulley, according to whether the cord is placed at the right-hand or at the left-hand side of the window. Obviously said arm may be made of sheet metal.

It will be observed that all of the devices entering into the structure as described may be manufactured at small cost. The shaderollermay be of the ordinary form; the yokebar is an ordinary stick of wood; the brackets 4 are made up from stamped sheet-metal blanks; the eye 4 and the guard Pare formed from a single piece of wire; the arm 13 is formed from a single piece of wire; the pulleys, while answering every requirement, are very simple, and ordinary curtain-cord will answer for the cords 5, o, 10, and 12.

The apparatus would be operative without the eyes 4 and guards 4 but by their use greater stability may be attained.

It will be observed that lateral movement of the roller and yoke may be prevented by connection with only the cord 10 and the omission of the cord 12; but in that case winds might blow the opposite end of the roller and yoke forward away from the window.

The nature of the blank, as illustrated by Fig. 9, will be readilyunderstood. The main rectangular portion marked 4 constitutes the sleeve 43 when folded upon the dotted lines a ct a. The part 4 constitutes the foot, and the part 4 constitutes the nprightafter it has been bent into the upright position upon the dotted line b. The apertures 14- and 14" receive the bu ffer-cord, as described in the next following paragraph. The part t may be bent in either direction with reference to the plane of the blank. Bending itin one direction will form a right-hand bracket, and bonding it in the opposite direction will form a left-hand bracket.

A buffer-cord 14 may be applied to each bracket 4 for the purpose of preventing noise and scratching during the movement of the yoke. Said cord is so placed as to bear against the window-frame and prevent the metallic bracketfrom touchingsaidframe. Thedrawings show a hole 14 through the foot 4 just below the sleeve of the bracket. Said cord extends from the rear through said opening and then upward and rearward around the sleeve and down behind the foot and then forward through the aperture 14". Each end of the cord maybe knotted to preventit from passing through the adjacent aperture.

The apertures 4 14, and 14" may be stamped in the forming of the blank shown by Fig. 9, and the cord is a simple and economical material to constitute such buffer, and the application of said cord is a simple operation.

I claim as my invention- 1. In a curtainfixture, the combination with the yoke bar, brackets, and curtainroller, of cords, 5, 6, and 10, guides for said cords at the upper portion of the window and a guide for the cord, 10, on the end of the yoke, a suitable device for fastening said cord, 10,.a guide-cord, 12, and a guide for said cord at the adjacent end of the yoke, substantially as described.

2. In a curtain-fixture, the combination with the yoke-bar, brackets, and roller, of cords, 5, 6, and 10, and two pulleys, one of which has a housing composed of a base, 8, and the upper and lower webs, 8", and a lateral web, 8, and front wall, 8 said lateral web being located between said cords, 5 and 6.

3. In a curtain-fixture, the combination with the curtain-roller, yoke having cordguides at its ends, cords, 5, 6, and 10, and pulleys, 7 and 8, of an arm, 13, applied to the housing of one of said pulleys, a cord, 12,

and a fastening device for the lower end of.

of'a wire folded to form the guard, 4, and secured within the sleeve of said bracket, substantially as described.

7. In a curtain-fixture, the combination with the yoke-bar, 3 and sleeved bracket, 4, of a wire folded to form an eye and the guard, 4 and' secured within the sleeve of said bracket, substantially as described.

In testimony whereof I have signed my name, in presence of two witnesses, this 10th day ofJune, in the year'1902.

JAMES A LYONS.
