porting part, with which members there arel associated lone or more adjustable parts -provided with suitable mountings or .brackets for the roller carrying the 'shade `or other part adapted to be Wound thereon. A

Although my invention is equally capable of use for mounting maps, tracings, and the like, I shall conne. my description to the more general use-viz., that of removably supporting adjustable window-shades-it being understood that my invention as claimed is not limited to any one speciiic use.

It is the common experience in mounting Window-shades or changing them about that not a little difiiculty is found in iitting the rollers and fastenings for the separate windows, and when such shades are to be transposed it usually becomes necessary to change the shades upon the different rollers or it them to new rollers.

In appliances which have previously been constructed for .accomplishing the adjustment of curtain-fixtures it is found that the fixed member or support commonly must be made too Wide to it upon the ordinary window-casing where such devices are usually mounted. Moreover, it is desirable that the. adjustablemember shall be securely locked while in use, but may be readily released by a single finger of the person removing or adjusting the window-shade. Accordingly I have provided a structure wherein a relatively narrow slide and supporting-bracket adapted to be secured upon any casement is equipped with a vertically-acting plunger operating against-a sprin normally to lock a toothed or notched sli e-bar bearing the bracket in any of its positions of adjustment,

I While bein@V readily releasedby pressure upon the thum -piece lying slightly above the level of the curtain. TheA features of this construction will be best appreciated by making reference to the accompanying sheet of drawmgs, illustrating the same, whereof- Figures I and .II are front viewsof right and left hand fixtures containing my invention. Fi III is a side view of the left-hand fixture ig. IV is an enlarged front view of the latter, partially inl section. Fig. V is a vertical sectional view on the same scale, showing the left-hand xture. Fig. VI is a view, partially broken away and designed to show the use of an adjustable fixture witha stationary bracket and an intermediate'supf. ported roller.

Throughoutv 'the several figures of this sheet of drawings I have employed the same character of reference to indicate similar parts.- MN

Referring particularlyy `to the `first type shown, it is seen that both the right and left handadjustable iixturesare supplied with 5 escutcheons or slides a, which are designed to be screwed to the woodwork of the window or door openin in a convenient location- Within a recess formed in the escutcheon. is provided a spring c, acting against a plun, ger d, equipped with a detent e. ThisI detent extends within the slide portion f of the escutcheon and engages teeth provided upon the extension-bar g, which mounts at its end either theright or left bracket h. By employing two of these devices it is apparent that a wide range of adjustment for the brackets is secured, which may be increased as desired by lengthening the toothed extensionbar. However, it is quite as practical and ordinary demands are met by employing a stationary bracket s in association with one of my adjustable fixtures, as indicated in Fig. VI

n, will be seen that the left-hand fixtureis 95` fitted to receive the flattened pivot part of the well-known spring-actuated roller r, and

when adjusted therebetween it is impossible for the roller and its pivot part to become accidentally unseated from its bracket even roo when the curtain is suddenly released and iiies up under the tension of the spring.

From a consideration of the foregoing it will be seen that the shield or slide member a is of as narrow construction as it is possible to 1o 5 make it and secure sufficient bearing for the extension-bar g, so that it may be screwed upon the :narrowest Wooden casing. The plunger d, with its thumb-piece, is readily actuated by a si ngle finger of the user for the 11o purpose of releasing the extension-rod g, which, however, is securely held under normal conditions in its adjusted position by means of the tooth e and spring c. The spring is conveniently and e'ectively positioned within the bore or recess b, so that it is not liable to become broken or lost, and the device as a whole is simple, compact, and cheaply constructed, as it must be in order to compete with stationary iXtures upon the market.

Having now described theieatures of my invention, claim as new, and desire to secure by Letters Patent, the following:

l. The combination with a base member provided with a lateral slide f, and an intersecting opening I), of a toothed extension-bar g, normally positioned within the slide, a bracket or support-7L, mounted upon said bar, a spring c, positioned in the lower portion of the opening l, and a vertically-acting plunger part d, equipped with a lateral detent e, and disposed Within the opening b, above the spring whereby the toothed extension-bar is normally held in its position of adjustment, substantially. as set forth.

2. In an adjustable roller support or iX- ture, the combination with a xed member adapted to be Secured in position for support and provided with a transverse slide or way, of a toothed extension-bar longitudinally movable therein, a bracket carried thereby, and a manually-operated locking member 'adapted to secure the adjustable parts fixedly together; comprising a vertically-movable plunger having a lateral detent e, and a spring normally forcing said detent into engagement with the toothed extension-bar, substantially as set forth.

3. In an adjustable roller support or iixture, the`v combination with a iiXed member adapted to be secured in position for support and provided with a transverse slide or Way, of an extension-bar longitudinally movable therein; the same having a rack along its lower edge, a bracket carried thereby, a manually operated locking member; the same comprising a vertical plunger extending above the supported shade-roller with a laterally and inferiorly positioned detent adapted to engage the extension-bar from beneath, and a spring acting thereon normally under tension adapted to secure the adjustable parts iiXedly together, substantially as set forth.

Signed at Cleveland, Ohio, this 6th day of June, A. D. 1906, in the presence of the undersigned Witnesses.
