NlTED STATES CHARLES W. KIRSCH, OF STURGIS, MICHIGAN.

CURTAIN ROD.

Application led January 29, 1920. Serial No. 354,816.

To a?? whom t may con-cem.

Be it known that I, CHARLES W. KIRsoH, citizen of the United States, residin at Sturgis, in the county of St. Joseph and tate of Michigan, have invented certain new and useful Improvements in Curtain Rods; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which'it appertains to make and use the same.

This invention 4has for its object to provide an improved curtain rod and more particularly to provide a curtain rod consisting of two equal opposed parts pivotally mounted on opposite sides of a window frame, each of which is adapted to have a curtain or drape suspended therefrom to be normally positioned substantially parallel with the window sashes and to be swung outwardly upon opening the window or when it is desired to cleanvthe same so as to be out of the path of. draughts of air entering or leaving the'windows and to prevent soiling of the curtains or drapes while washing the windows.

The present invention relates more particularly to means for latching o'r firmly holding the curtain rods in normal position while permitting ready movement thereof to their outward position without placing any considerable strain upon the curtains or drapes suspended from the rod and by means of which it is adapted to be operated.

The invention consists in features of construction and combinations of parts hereinafter fully described and particularly claimed.

In the accompanying drawings illustrating suitable embodiments of the invention:

Figure 1 is a fragmentary viewV front elevation of a window frame equipped with a pair of curtain rods constructed in accordance with the invention.

Figure 2 is a fragmentary top plan View of the window frame and curtain rods mounted thereon.

Figure 3 is a perspective View of one of the end members of the curtain rod and a bracket in which it is pivotally mounted.

Figure 4 is a plan section on the line 4,-4 of Figure 1 showing the rod and bracket detached from the window frame.

Figures 5 and 6 are sectional views similar to Figure 4 showing modified forms of construction.

Each of the members of the complete curtain rod comprises the bracket A consisting of a plate of sheet metal having a plurality of projections B provided with openings for the passage of nails or screws for securlng said Aplate to the window frame or the llke, and which is also equipped with a palr of opposed parallel anges C in the outer ends of which a pivot vpin D is mounted.

Suitably secured to the plate A is a fiat sprmg E, the body ortion of which lies flatupon said plate. ne end of said spring E 1s bent to project outwardly from the plate A and provides an ogee curved forma-y y tion or tongue F which is very flexible and is adapted to engage the curved end portion Gr of the flange H integral which is with the curtain rod member I. The latter is formed of sheetmetal and presents a fiat outer face or web having overturned side flanges J and bein C-shaped in the cross-section as shown in Figure 3.l The said member I is provided with two arms extending substantially at right angles to each other, the outer arm K being adapted to telescopically receive an extension memberI L such as is shown in Fi ures 1 and 2.

he outer or free end portion of the tongue F of the spring E is normally positioned near the pivot pin D than the outermost convexv face of the projection G of the flange H of the rod so that as the rod is turned in one direction to the position shown in Figures 1 to 4 inclusive, the said convex face of the tongue G will be sprung past the outer end portion of the tongue F. The free end portion of the latter will then i bear upon the free end Iiortion of the tongue G to retain the flange and rod member I firmly in position shown in said Figures 1 to 4. When it is desired to turn the rod from the positions shown in said ligures so that the extension member L and arm K will extend substantiallyl perpendicularly to the window frame or the plane of the plate A, the curtain or drape suspended from the rod will be drawn back and tension imparted to the extension member L to overcomethe resistance vof the tongue F of the spring to the passage of the tongue G of the flange whereupon the rod will readily turn to the desired position and will be easily returned to its normal position in the same manner.

While I have shown the preferred construction embodying the invention in Figures- 1" to 4 inclusive, such construction may be variously modified and suitable exemplary modications are illustrated in Figures 5 and respectively.

In Figure 5 Will be noted that the rod member I is devoid ofthe flange H- and tongue G and that it terminates at `a` point spaced from the plate A. The latter car- `rles aflat spring M which-is bent to pro vide a curved stop formation N against which the web of the inner end of the rod member lying betweenthe pivot pin D and plate A normally abuts. The curved portion N is continued in a double ogee curved formation which provides a convex shoul;

der O over which the inner end of the member I must be sprung in turning the rod to and from the position shown in Figure 5 in an obvious manner. The extreme free end portion P of said-spring normally bears upon plate A and will move slightly 1ongitudinally along the same as the convex portion O is depressed or forced toward the plate A under the infiuence of the pressure exerted thereon by the passage of the end of the rodV member I over the same.

In Figure -6,.the plate A is shown as provided at one end with an ogee curved tongue or flange Q projecting outwardly from the outer face of the plate A and extending substantially perpendicularly to the flanges C. The said tongue or flange Q presents an outer. convex face R over 'which the ogee curved, -free end portion S of the spring T which is riveted or otherwise rigidly secured to the flange U, corresponding to the ange `I-I shown in Figures 3 and 4, is adapted to ure 6 is identical with that shown in the remainin figures.

While gl have shown the preferred em` bodiments of the invention in the accompanying drawings, it will `be understood, of

course, that such embodiments may be changed and varied in details without departing from the invention as -defined in the appended claims.

I claim as my invention: v The improvements herein described l prising a sheet metal bracket provided with two parallel forwardly extending projections, an angle member pivoted at the free end, of one of its legs between said pro' jections toswing horizontally, and means for yieldingly retaining said angle member in normal. position comprising an integral extension' onthe anglememb'er bent at ri ht rangles past the pivotal connection, its ree end curved outwardly, and a flat spring secured at one end to the bracket and extendy ing between said projections and having its free end curved outwardly to engage the free end of the projection on the angle member, as and for the purpose specified.-
