' Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed lay 25, 1900. Serial No. 484,973.

To all whom it may concern:

Be it known that I, CARL WOWRA, a citizen of the United States and residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in CurtainPole Hangers, of which the following is a complete specification.

This invention relates to improvements in curtain pole hangers and more particularly to a curtain pole han er of that class adapted to lower the pole wIxen it is desired to remove the curtain from or place it upon the pole. Heretofore curtain pole hangers of this class have ,been devised but they have usually been provided with cords and pulleys for the purpose of raising and lowering and supporting them in their adjusted positions. In such constructions it is necessary that the cords be kept properly adjusted to hold the hangers in true relation to each other, and it is also necessary to secure the cord after thecurtain has been adjusted to prevent further movement.

The object of this invention'is to provide a curtain pole hanger adapted to raise and lower the curtain with out the use of supporting cords or other similar devices which it is necessary to secure to hold the curtain in its adjusted position.

It is also an object of the invention to provide a curtain pole hanger adapted to be locked in its lowermost position, and which,

when released, will automatically return to its upright position and carry the curtain upwardly to its position in front of the window or other opening which it is to screen.

It is a still further object of the invention to provide a device in which the tension of the raising mechanism may be adjusted to regulate the folding movement of the hanger so as to adapt it to curtains of different weights.

The invention consists of the matters hereinafter described in the specification and more fully pointed out and defined in the appended claims.

, In the drawings: Figure 1 is a perspective view of a window provided with a pair of curtain hangers embodying my invention. Fig. 2 is a fragmentary, side elevation, partly in section, of one of the hangers. Fig. 3 is a fragmentary, front elevation of the hanger showing the arm in elevated position and the casing in section. Fig. 4, is an end elevation of the slidable collar. Fig. 5 is a perspective view of the ferrule for the curtain pole.

ta-in pole hanger indicated as a whole by B and on which the curtain pole C is hung. Sa1d hangers are identical in construction so that a description of one will sufiice for both, and, as shown more clearly in Fig. 2, 12 indicates an attaching plate of any preferred construction and material adapted to be rigidly engaged to the wall or other su portat one side of the window. Near ti de bottom of said plate is a forked stud b which is riveted or otherwise rigidly secured thereto, and ivoted in the fork of said stud is a threade adjusting bolt b Adjustably engaged on said bolt is an arm. B, which may be of any preferred construction but which, as shown, comprises a plurality of telescoping sections secured together by means of collars b 'on the overlapping ends of the sections and having set screws 1) which extend therethrough into engagement with the inclosed ends of the. sections. In the rear end of said arm is rigidly engaged a nut Z) which has threaded engagement with said bolt and isprovided with a flange which projects laterally beyond the arm. Slidably engaged on said arm is a collar D having apertured lugs cl thereon between which is pivoted one end of a joint bar d, the other end of which is pivoted to a lug 03 near the upper end of the attaching plate I). Said bar d is provided with a central joint which breaks downwardly, and when the two sections of the bar are in alinement, as shown in Fig. 2, the arm B, bolt 6 and stud b are held in approximately axial alinement. On each side of said arm B is a connecting hard, the forward ends of which are pivoted to the sides of the collar D by means of pins 0Z Said bars extend rearwardly and upwardly and are pivoted to lugs d on the plate 6 and which are located. above the stud b. A coiledspring E is carried on said arm and engages at one end against the flange of the nut 12 and at the other end against the collar D, and acts nor-.

mally to force the collar longitudinally of the arm. A casin F, which, as shown, is open at its ends an on one side, incloses the rear portion of said arm and is pivoted at its rear end to ears f on said plate slightly above the stud b, and at its forward end is provided in its sides with slots f through which the pins d extend to support the forward end of the casing. On the forward end As shown in said drawings: A indicates a window, at either side of WlllCh 1s a curof said arm is a hook G, having a bearin seat g thereon, formed by the inturned en y of the hook at one end, and by a shoulder at the other, and slidably engaged therein 5 is a ferrule H adapted to support one end of the curtain pole. Said ferrule is provided with a T shaped member adapted to slidably engage on said seat and the shank h of said T shaped member is slotted to receive the hook G therethrough, and the ends of the cross head it are slotted to straddle said hook so as to. prevent the ferrule from swing ing laterally, but permitting it to slide on said seat when the arm B is operated. Any preferred means may be provided to look the arm in upright position but, as shown in Fig. 3, a notched catch I is enga ed to the plate 6 near the top thereof, an a curved leverI is pivoted on the plate on the opposite side of the arm from said catch, and 1s adapted to be turned in front of the arm when the latter is raised and to engage in said catch.

The operation is as follows: When it is desired to adjust the curtain J upon the pole, or to remove it from or place it u on the pole, the arms B are swung downwar ly, as shown in Fig. 1, thereby lowering the polesufliciently to enable a person to reach it from the floor. When in this position the spring E is under tension and'is exerting pressure against the collar D, but the joint bar d being now straightened out prevents movement of the collar and consequently prevents the arm. from returning to its upright position. When however the joint (1 of said bar is pulled downwardly the arm is turned upwardly out of alinement with the stud b and the spring acting on said col- .40 lar tends to force the latter longitudinally of the arm. Inasmuch as the connecting bars d tend to prevent the collar from moving farther away from the plate I), and inasmuch as they are pivoted at their rear ends above the pivotal point of the arm, they act to swing the arm inwardly against the plate as the spring forces the collar longitudinally of the arm. This action is caused by the fact that when the bars 03 assume an upright position the distance between the pivotal point of the arm and the collar is greater than when the arm is down, thereby permitting expansion of the spring when the arm is raised and contraction when it is lowered. The tension of the spring may be r ated by adjusting the arm on the'bolt 6 When the arms assume an upr' ht osition the T members of the ferrules slide in the bearin g of the hooks G and thereby retain their vertical positions.

Obviously the arms B may be. adjusted to make them any desired length and obviously also many details of form and construction may be varied without departing from the principles of my invention.
