windovy at will without UNITED STATES To all whom it may concern:

Be it known that 1, WILLIAM H. RICHMOND, of Mount Pleasant, in the county of Isabella and State of Michigan, have invented an Improvement in Curtain-Fixtures, of which the following is a specification.

The nature of my invention relates to new and useful improvements in the construction and operation of curtain-fixtures, by means of which roller-curtains are suspended in front of the window, wound or unwound upon a roller actuated by a spring, and adjusted to cover any portion of the window at will.

With spring -roller curtains as commonly used the roller is journaled in suitable brackets secured to each side of the window-frame, at the top thereof. In this case it is impossible to prevent the admission of sunshine through the lower partof the window without drawing the curtain down to cover the entire Sometimes these spring-rollers are attached to the bottom of the window-frame, and the curtain is drawn up to cover the window by means of a cord running over a small pulley at the top of the frame. In this case the top of the window cannot be shaded without shading the whole of it. Others who desire to shade any part of the being compelled to shade the whole employ two curtains secured to two separate spring-rollers, both being journaled at or near the vertical center of the frame, the one being designed to pull down to cover the lower part of the window, and the other to pull upward to cover the upper part of the same. As each of these curtains acts independently of the other, it will readily be seen that the upper or lower or center part of the window may be shaded at will, and that the brackets in which the rollers are journaled are rigidly secured to the window-frame.

The object, therefore, of my invention is so to construct curtain-fixtures that by the employment of one curtain with a spring-roller, which is journaled in brackets which are not rigidly secured to the window-frame, the window may be shaded in any desired part without shading other parts.

The invention consists in the peculiar construction and operation of the necessary means WILLIAM H. nrornuonn, or MOUNT PLEASANT,

to accomplish the desired result, as more fully hereinafter described.

In the drawings, Figure 1 is a perspective View of my invention applied to a windowframe. Fig. 3 represents the two levers detached fronri the frame and from each other. Fig. 2 represents, in perspective, the movable brackets in which the ends of the spring-roller are supported. the opposite ends of the spring-roller.

Like letters indicate likeparts in each figure.

In the accompanying drawings, which form a part of this specification, A represents a spring-roller for curtains, one end being provided with a flanged head, a, as shown, to retain the journal b in engagement with the slot 0 in the bracket B, in which the journal re volves. The opposite journal, b, is squared on two sides, as shown at d, to engage with the rectangular slot 6 in the bracket (1, and terminates in a T-shaped head, h, to retain the end in its engagement with said bracket. These brackets B O are suspended, as shown in Fig. 1, from cords i and i. The cord z, to which the bracket G is suspended, passes up and around a small sheave, 7a, (a wire loop or eyebolt would answer,) to change the direction of the cord. This cord then passes over the holderD,through the groove m thereof. This holder is rigidly secured to the top of the window-frame, as shown, and its lower end terminates in a projecting lip, a. The cord t, to which the bracket B is suspended, passes up and around the similar sheave and then over the lever E, through the groove 0 thereof. This lever is pivotally secured to the holder or fixed lever D by a bolt or screw passing through the holes 19, which, when the two levers are in place, are coincident. a loop, 8, through which both cords 11 and 11 pass, and their free ends may be secured to a tassel, t, common to both. The lip it enters the groove 0, and the weight of the curtain or roller hanging upon the upper end of the pivoted lever E compels the lip to gripe or so impinge against the cords z 13, before they pass through the loop 8, as to prevent their slipping.

If it is desired to pull the spring-roller upward, pulling upon the cords will force the lower end of the lever E away from the lip Fig. 4. is a perspective view of This lever is also provided with IO readily adjusted to any brackets B 0, having slots 0 6, described, substantially as and specified.

2. As a means of securing the cords i 1." in position, the fixed leverD,provided With groove m and lip n, and the pivoted lever E, provided with groove 0 and guide-loop s, substantially as and for the purposes set forth.

3. In combination, the brackets B (J, suspended by the cords 27 i, the sheaves k k, and levers D E, constructed as described, with a spring-curtain roller, substantially as and for 3 the purposes described.

and allow the cords to run freely. After drawing the roller to the position desired, slacken up the tension on the strings, and the weight of the curtain or rolleris thrown upon the upper end of the pivoted lever. Compelling it against the lip secures the cords again.

The curtain F, hung upon the spring-roller, which may be of the ordinary construction, except as hereinbefore described, may be as desired position as where the brackets are rigidly secured to the window-frame.

What I claim as my invention, and desire to secure by Letters Patent, is
