WINDOW-SHADE FIXTURE.

SPECIFICATION forming part of Letters Patent No. 642,468, dated January 30, 1900.

Application filed November 2, 1899. Serial No. 735,625. (No model.)

To all whom t may concern:

Be it known that I, MATTHEW A. MARR, of the city ot New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved l/Vindow- Shade Fixture, of which the following is a full, clear, and exact description.

This invention relates to improvements in Window-shade lixtures of the class in which the roller carrying the shade kis-adapted to be moved up and down with relation to the Window-casing, so that light may be admitted over the top while the shade closes over or partly over the lower portion of the window; and the object of the invention is to provide a fixture the brackets and guide-rails of which are so constructed that there can be no lateral play of the brackets or any displacement of their axial relation to each other, thus insuring an easy and even adjustment of the shade-roller.

A further object is to provide a simple means for preventing an accidental displacement of'the roller from its brackets; and a still further object is to provide the roller with a longitudinal spring-yielding bearing to permit of its automatic adjustment to possible varying widths betweenthe side rails of a window-casing.

I will describe a window-shade fixture embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an elevation showing a fixture embodying my invention applied to a windowcasing. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section showing a means for permitting longitudinal adjustments of the roller. Fig. 4 is a side view of one of the brackets, and Fig. 5 is a cross-section of a guide-rail made of sheet metal.

Referring to the drawings, 1 designates a roller of the usual spring form and to which the shade 2 is attached. A block 3, extended through one end of the roller and having connection with the spring in the roller, is seated in a bracket 4t and is held from accidental displacement from the bracket by means of a set-screw 5, engaging in a tapped hole in the bracket and impinging against the block. This screw also holds the block from longitudinal movement in the bracket. At the opposite end a bearing-pin 6 is designed to rotate in a bracket '7, and on the outer end this pin has a head 3 to prevent its movement inward relatively to the bracket. The bearing-pin 6 hasa spring-yieldinglongitudinal movement relatively to the roller 1. As here shown, a spring 9 surrounds the bearing-pin within the roller, the said spring bearing at its outer end against a plate 10, secured to the end of the roller and through which the bearing-pin is movable, and at the other end the said spring bears against a pin 11, passed through the bearing-pin. A pin 12 is passed through the roller 1 and through a longitudinal slot 13 in the bearingpin. This construction will permit the bearing-pin to move longitudinally, but will cause it to rotate with the shade-roller. The object of the spring-yielding bearing-pin is to permit of longitudinal adjustment to accommodate the fixture to possible varying distances be-V tween the side rails of a window-sash from its top to its bottom, as sometimes occurs by the settlin g of a building.

The brackets 4 and 7 are substantially of similar construction and may be of cast metal or stamped. Each one has an inwardly-extended arm 14 at its upper end and an inwardly-extended arm'15 at its lower end, these arms being respectively above and below the parts in which the block 3 and bearing 6 engage, so that the brackets will be prevented from tilting forward under the weight of the shade. The arms 14 and 15 have vertical substantially V-shaped openings in which correspondingly-shaped guide-rails 16 engage, these guide-rails being secured to the opposite side rails of the window-sash. The guiderails have their inner surfaces 17 made lat and bearing closely against the flat wall of the openings through the arms 14 and 15, and as the rear and front walls of these openings engage with the web portion of the rails it is obvious that there can be no lateral play of the brackets relatively to the rails, as occurs when round or substantially round guiderails are employed. The rails may be made IOO of solid metal, as indicated in Fig. 2, or they may be made of sheet metal bent into form, as indicated at 18 in Fig. 5.

From the bracket 7 a cord 19 passes overa roller 20, arranged in the upper portion of the Window-sash at one side', thence overa pulley 21 at the other side, and then down to a connection with a clip 22, and from the bracket 4 a 'cord 23 extends over the pulley 2l, and thence through openings in the clip 22, which secures the cords together in such manner that they will pull evenly upon drawing downward on the cord 23. Obviously by drawing up on the cord 23 the roller carrying the shade will be moved upward, and by loosening the strain on the cord the Weigh-t of the shade and its roller will move the shade downward. When the shade and its roller are properly adjusted as to height, the cord 23 is att-ached to a suitable cleat 2l on the window-casing.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a window-shade fixture, a roller, guiderails, brackets mounted to slide on the guiderails, a pin having longitudinal spring-yielding connection with the roller at one end, and a head on the pin adapted to engage the outer side of one of said brackets, the tendency of the spring being to draw the pin inward, substantially as specified.

2. In a Window-shade fixture, guide-rails, brackets mounted to slide on said guide-rails, a roller, a bearing-pin extended from said roller, a pin extended through the roller and through a longitudinal slot formed in the inner end of the bearing-pin, a spring arranged Within the roller, and surrounding the bearing-pin, said spring having a tendency to cause an inward movement of the bearing-pin,

and a head on the outer end of said pin for engaging with the outersurface of the bracket in which the pin is supported, substantially as specified.
