EXTENSIBLE SHADE-HANGER.

SPECIFICATION forming art of Letters Patent No. 517,750, dated April 3,1894. I Application filed October 11, 1893. Serial No- 487,856. (No model.)

To all whom it may concern:

Be it known that I, JACOB JOSEPH, a citizen of the United States, residing in Shamokin,-in the county of Northumberland and State of Pennsylvania, have invented certain part of this specification, and in which- Figure 1 is a perspective view of my extensible and adjustable hanger. Fig. 2 is a top or plan view. Fig. 3 is a rear view of a portion of the hanger. Fig. 4 is a transverse sectional view on line mm in Figs. 2 and 3. Fig. 5 isa detail view of the hinged clasp or clamp. g

Like letters of reference designate corresponding parts in all the figures.

This invention has relation to extensible hangers for window-shade rollers, and my improvement consists in the novel construction and combination of parts of an all-metal adjustable hanger as will be hereinafter more fully described and claimed.

On the accompanying drawings, the letter A denotes one of the slidable bars,'and B the other parallel bar, both being made of metal (preferably malleable strap-iron), of suitable dimensions to give the necessary stiffness and rigidity to the device without making it un-,

necessarily heavy. These bars are flat, as shown on the drawings, and are bent at right angles at their outer ends, so as to form an elbow A on bar A, which has a centralaperture a for the insertion of the tenon or pivot on the shade roller (indicated in dotted lines), while the other elbow B of bar B has a slot 1), adapted-to receive and forma bearing for the squared tenon at the other end of a springroller. The outer ends of these elbows or bearings A and B are bent inwardly, as shown more clearly in the top View, Fig. 3, to make room for the projecting ends of the roller pivots or trunnions, when the roller is placed in the hanger, in theposition shown in dotted lines. At its other or inner end, the

flat bar A is made with a rectangular loop-C,

which is bent or deflected outwardly so as to make room for the insertion of bar B; the

end piece a of this loop being thinned out to bar B is made with a terminal loop or bail D at its extreme inner end, of 1 precisely the same size, shape, and construction as the loop 0 appertaining'to bar A and for the same purpose, viz: the insertion and holding ofthe slidable bar A. It will thus be seen, that bars A and B areconnected, movably, to each other by the deflected end-loops O and-D, in such manner that they can slide upon one another in the direction of their length, so that the compound bar, comprising" the two slidable parts or sections A and B, may be extended, as shown in dotted lines, to correspond to the length of the shade-roller.

In practice, it is best first to adjust the hanger to fit the roller, and after this has been done, the hanger is placed in its proper position in the window frame or casing, and fastened securely by means of screws or nails inserted through holes, at d, punched or drilled in the slidable arms A andB for that purpose.

After the'hanger has been properly adjusted to fit the shade-roller, the'slidable parts A and B are locked together by means of a hinged friction clamp or clasp E, having an extension F by which it is fastened, bya rivet f, upon the front side of the bar A; the riv eting being loose enough, however, to permit the clasp to turn on it as upon a hinge or pivot. This clasp is made of spring steel, with its sides'or flaps e e bent slightly toward each other, as shown ,in Fig. 5, and one of said flaps on its inner side formed with an inwardly projecting rib g, which is adapted to engage any one of a series of equidistant notches or depressions'G, G, in the rear side of bar B. These notches are simply equi-disor back upon bar A until the clasp has been again raised, so as to disengage the rib g from its appropriate notch G.

In order to prevent the squared springtenon of the roller from slipping out of its bearing in arms B B, the slot 1) is made with a lip, 11', overhanging the opening or inlet to the slot, so that the roller cannot become accidentally dislodged or displaced from its bearings in the adjustable hanger.

It will be seen that myimproved extensible or adjustable hanger is made exclusively of metal (iron), in a form (flat bar-iron, or strapiron) in which this comes in the marketfrom the rolling-mills and foundries, so that the bars A and B require no other manipulation to adapt them for my hanger than the formation of the elbow-bearings A and B, the slidableloops C and D, and punching the holes (1 d for the insertion of the permanent fastening nails or-screws. The only other part is the pivoted friction-clasp E, which'can be stamped out of a thinsheet of suitably tempered spring steel,:and is easily bent to its proper shape. This hanger can be made,

. shade rollers, thecombination with the slid able bars A and B, provided respectively, with the elbow bearings A and B deflected loops 0, D, and apertures cl, d, and one of said barsformed on its outer side with a series of equidistant notches, of the spring clamp E, hinged to one of said bars and provided with an inwardly projectingrib g,

adapted to engage with said notches, substantially as described.

In testimony that I. claim the foregoing as my own I have hereunto affixed my signature in: presence of two witnesses.

JACOB JOSEPH.
