BEARING-BRACKET FOR VERTlCALLY-ADJUSTABLE SHADE-ROLLERS.

$PEGIFICATION forming part of Letters Patent No. 697,114, dated April 8, 1902.

Application filed April 13, 1901. Serial No. 55,744. (No model.)

To all whom it may concern.-

Be it known that I, CALVIN P. THOMAS, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Bearing-Bracket for Vertically-Adjustable Shade-Rollers, of which the following is a specification.

This invention relates to apparatus for hanging window-shades, and has for its object to provide improved means for adjustably supporting the shade-roller so that it may be conveniently raised and lowered and also to provide an improved form of rollerbracket for use in conjunction with the elevating means.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings,and particularly pointed out-in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without cleparting from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a front elevation illustrating the present apparatus in use for supporting a shade-roller. Fig. 2 is a detail end view of the shade-roller with the adjacent roller-bracket thereon. Fig. 3 is a detail perspective view of the bracket removed. Fig. 4 is a detail perspective view of the adjustable clamp for holding the curtain-sup porting cord. Fig. 5 is a detail sectional view thereof. Fig. 6 is a detail sectional view of the adjusting device for the clamp-guide. Fig. 7 is a detail end View of one of the rotatable guide-tighteners.

Like characters of reference designate corresponding parts in all of the figures of the drawings. As shown in Fig. 1 of the drawings, the shade-roller 1 is hung from the opposite ends of a looped supportin g-cord 2, which is passed through the respective guide-pulleys 3, that are mounted in the looped brackets l, secured to the upper portion of the window-frame.

For the connecction of the spring-actuated pintle or journal of the shade-roller to one end of the supporting-cord there is provided a roller-bracket comprising a bowed springrod member 5 (shown in Figs. 1, 2, and 3) and having the opposite terminal eyes 6,which are designed to slidably receive the upright guide rod or cord 7, that is secured to one side of the Window-frame'in any ordinary manner. This spring member isembraced by a flat link member 8, that is bowed reversely with respect to the former member and is provided with a longitudinal slot 9 for the reception of said former member, the pintle of the roller being clamped between the two members. To apply the bracket, the opposite ends of the spring member are pressed inwardly by the thumb and forefinger of the hand, so as to bring the sides thereof closer together, and thereby permitof thelink mem her being slid laterally inward, so as to readily.

receive the pintle between the two members, after which the spring member is released, whereby the opposite ends thereof spring out wardly, and thereby force the link member .snugly into contact with the pintle to clamp the latter between the two members. The bracket slides freely upon the guide 7, so as to prevent turning thereof, and the adjacent end of the supporting-cord is secured to the upper terminal-eye or at one side thereof, as

a laterally-projected open-ended and opensided pintleseat, which is projected through the slot in the other member, whereby the inner open side of the seat is closed and the inner open end is unobstructed. Furthermore, when the member 5 has been compressed between the fingers and then released the opposite ends thereof spring outwardly, thereby forcing the plate or link member outwardly and clamping the springpintle between the two bracket members, so as to hold the pintle fixed against rotation.

The intermediate looped portion of the supporting-cord 2 is passed outwardly through the pulley that is opposite the spring-actuated pintle of the roller and hangs downwardly at the side of the window-frame.

For the adjustable support of the supportin g-cord, so that the roller may be raised and lowered, there is provided a cord-holder, consisting of a clamp formed by a doubled or folded springstrap, as at'11, the opposite ends thereof being bowed outwardlyin opposite directions,as at 12,to form substantially semicircular jaws, each of which is provided with the opposite terminal and alined perforations 13 and 14. A stop-plate 15 is located between the spring members of the clamp or holder and just above the bowed jaws thereof, said plate having opposite terminal projections 16, that extend outwardly through corresponding perforations 17 in the spring members, said projections being provided with perforations .18 to correspond to those in the adjacent jaws.

For the support of the clamp there is provided a pair of parallel guides 19, formed by a doubled wire passed through the looped bracket of the adjacent roller 3 and extended downwardly across the window-frame,the opposite ends of the wire being connected to tension devices applied to the frame. The clamp lies between these guides, with the latter passing loosely through the alined perforations of the part 15 and the jaws, whereby the normal outward tension of the spring members of the clamp frictionally grips the guides between the sides of the spring members and the plate 15, and thus adjustably support the clamp upon the guide. The looped portion of the supporting-cord 2 is passed between the spring members and is thereby adjusted with the clamp or cordholder. It will be understood that the bowed jaws form finger-pieces for convenience in pressing the spring members inwardly to release the grip thereof upon the guide.

Each lower end of the wire guide is seated in a diametric groove or seat formed in the head of a rotatable fastening and tension device 20, carried by a block or bracket 21, that is secured to the window-frame, so that by turning the tension devices by means of a screw-driver the wire-guide may be conveniently maintained tight.

What is claimed is 1. In a windoW-shade-hanging apparatus, the combination with an upright guide,' of a roller-bracket comprising oppositemembers, of which one member has opposite slidable connections with the guide, and an intermediate laterally-projected pintle-seat, and the other member has an intermediate slot through which the pintle-seat is projected, and a shade-roller having a spring-actuated pintle seated in the seat and rigidly clamped between the members of the roller-bracket.

2. A shade-roller bracket comprising oppo site reversely-bowed members, of which one has a longitudinal slot, and the other is a spring'member having its intermediate portion projected through the slot from the convex side of the first-mentioned member, and also provided with opposite terminal guideopenings, the opening between the intermediate portions of the two members forming a pintle-receiving seat.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

CALVIN P, THOMAS.
