ADJUSTABLE SHADE-ROLLER.

Application filed June 28, 1919.

To all whom it may concern lie it known that I, EDWARD L. FLEMMING, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylmnia, have invented certain. new and useful Improvements-in Adjustable Shade-Rollers, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to a shade roller, and more particularly to an extensible roller that can be easily ad usted to fit windows or window frames of different widths.

The object of the invention is the construction of an expansible roller which is provided with simple and efficient means for allowing a shade to be tacked or fastened to the roller throughout its length, irrespective as to the adjustment or length of the roller.

With this and other objects in view, my invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereimifter specifically de scribed, illustrated in the accompanying r lrawings, and more particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a longitudinal, sectional view of a roller constructed in accordance with the present invention, showing a shade attached thereto.

Fig. 2 is a longitudinal, sectional view of the roller, with the shade removed, showing the sliding parts of the roller somewhat closely together to illustrate more clearly the adjustment or expansible principle of the roller.

Fig. 3 is a perspective view of the piston device of the roller.

Fig. 4 is a sectional view of the hollow, primary section of the roller.

Referring to the drawings by numerals, 1 designates the hollow, primary section, and 2 the piston device.

The hollow, primary section is provided with a wooden plug or closure 3 extending into the section 1 at 4, and. a tack 5, extending through aperture 6, serves to hold the plug in the outer end of easing or section 1, and also serves to partly attach the shade 6 to the roller (Fig. 1). A suitable bracket pintle 7 is attached to plug 3. The casing or section 1 is provided. with a plurality of apertures 8 intermediate its ends, preferably near its middle, and said section is also provided with an aperture 9.

Specification of Letters Patent.

Patented Ma, 25, 1920.

Serial No. 307,312.

The piston device comprises a body 10, a primary piston 11 of a reduced dimension compared with body 10, and an auxiliary piston 12 is attached to the outer end of the primary piston 11 by a flexible connection, cord 13, for instance; the cord 13 is attached by a tack 1 1 to the extreme outer end of the piston 11, and said cord is attached by tack 15 to an end of the auxiliary piston 12.

Suitable means, as a coil spring, can be placed within the end 16, attached to the outer end of body 10, and to this extreme outer end 1.6 is secured an ordinary pintle '17- to engage a bracket. I make no specific claim to the means for rewinding my roller, as any means known. to the art may be uti lized in constructing my roller for rewind.- ing the same.

The operation ofthe device is as follows: The auxiliary piston 12 is placed in the hollow casing or section 1, and pushed i11- wardly by the outer end of the primary piston 11, the aliixiliary piston 12 being pulled mitwardly by the flexible connection 1?, being attached to the primary and auxjiliary pistons, so that the auxiliary piston 12 can be accurately placed under the apertures 8, whereby tack 18 can be passed through the shade 6 and into the auxiliary piston (Fig. 1), affording an excellent securing means for the tack; then the primary piston can be adjusted within the hollow section. 1 to obtain the desired length for accommodating the roller to a given window or window frame. Several adjustments of the piston device within the hollow section 1 can be obtained, hence making it possible to secure a number of adjustments of the roller to different size or width. windows. The auxiliary piston 12 always affords an excellent foundation or fastening means for the tack 18, whereby the shade 6 can be fastened securely throughout its width to the roller, as a tack 19 is passed through the aperture 9 of the section 1 and into the primary piston (Fig. 1), and tacks 20 are used to fasten shade 6 to the body of the piston device.

I have found from actual experience with my improved roller, that the direct connecting of the auxiliary piston by a flexible means to the primary piston produces a marked advantage in allowing the adjust ment of the piston device upon the hollow casing and affording satisfactory means for supporting tacks securely upon the metal portion or section 1 of an cxpansible or extensible roller.

In carrying out my invention, 1 may find that certain minor changes or alterations will be desirable, and I reserve the right to make such alterations or changes as shall appear to one prisinga body, a primary piston secured to said body and being of a reduced size com- :pared with the body, an auxiliary piston, a

flexible connection fastened near its ends to the contiguous ends oi the prlmary and auxiliary pistons, said primary and auxiliary pistons positioned within the primary seetion, and fastening means extending through the apertures of the primary section and into the primary and auxiliary pistons for securing the same in adjusted positions within the primary section.

2. In a device of the class described, the combination of a hollow casing or section, said section provided with an aperture near its center, a piston device including a body and a primary piston, said primary piston extending into the hollow section, an auxiliary piston in said primary section, and means cooperating with said primary and auxiliary pistons for placing the auxiliary pistonbcneath orin alinement \viththe aperture of the primary section whenthe piston device is adjusted u'ponthe'primary section.

In testimony whereoii l. liereunt'o aifiix my signature.

EDWARD LAWRENCE manure.
