CURTAIN-FIXTURE Specification of Letters Patent.

Patented March 23, 1909.

Application filed May 19, 1906. Serial No. 317,760.

To all whom it may concern:

Be it known that I, ALEXANDER HANsEN, a citizen of the United States, residing at Dorchester, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Curtain-Fixtures, of which the following is a specification.

This invention relates to curtain fixtures and more particularly to vertically adjustable curtain brackets, the object being to provide a fixture with adjustable brackets so that the curtain can be lowered out of the way to enable the room to be thoroughly ventilated.

Another object of my invention is to provide means for locking the brackets without any danger of the brackets being pulled down when the curtain is operated.

Another object of my invention is to provide'means for operating the brackets so that both can be operated at the same time, thereby preventing the same from wedging when allowed to drop.

With these objects in view, the invention consists of the novel features of construction,

'hereinafter fully described and pointed out in the claims.

In the drawings forming a part of this specification :Figure 1 is a perspective view of my improved fixture showing it attached to the window frame, and the curtain in place. Fig. 2, is an inside perspective view of one of the shade bracket supports. Fig. 3, is an outside perspective view of one of the shade bracket supports. Fig. 4, a

having outwardly extending angled perforated arms A at their top and bottom, through which screws are adapted to pass and secure the plate to the window frame. Projecting inwardly from the top of each plate are spaced apertured ears A between which grooved pulleys B are mounted, for the'purpose hereinafter described. A plate C is secured on the outside of each of the plates A adjacent its upper end, and has a cam-edge C, a square upper edge C having an upwardly projecting pointed lug 0 formed at one end thereof. A pointed lug D is secured to each of the plates A over the plate C, the point of said lug extending down below the point of the lug C. The edges of the plate A are split and punched inwardly adjacent the upper arms forming stop lugs 10 for the purpose hereinafter described.

The bracket is formed out of a plate E having reduced slotted ends E, provided with tongues E and apertured ears E and being bent on the dotted lines E to form acasing shown at E having guide-arms adaoted to work on the edge of the plate A, and be securely held thereon by the tongues E, which are bent inwardly forming guides. A plate F having reduced ends F is adapted to fit in the slots of the ends E and to be secured between the same. The plate F, is provided with a tongue bent to form an eye in which the wire spring G is secured, the ends of the springs bearing against a screw H, secured in the arm H, pivoted on the under side of the plate F. The arm H is provided with an inwardly projecting lug H at its end for the purpose hereinafter described.

One of the casings is provided with a round opening and the other with a slot adapted to receive the ordinary shade roller.

A bracket 1 is secured centrally to the window frame provided with s aced grooved pulleys I, over which the one s of the cord J are adapted to pass, and extend over the pulleys B, and have their ends connected to the a ertured ears E. A rin K carrying a tasse is mounted on the cord The operation of the device is as follows The stationary members or fixtures A are secured to the window casing, and the shade roll is mounted to the movable members E by inserting the ends thereof in the slots in i said members. When it is desired to raise l the curtain from the position shown in Fig. 1,

the operator pulls upon the cord J and moves the brackets or members E upward until the members E engage the fixed stops or lugs 10. On the upward movement of each movable member or bracket E, the lug H engages the cam edge C of the cam plate C, which latter is located with relation to the normal position of the lug H so as to insure said engagement, (see Fig. 4). After the lug H has engaged the cam edge C, further upward movement of the bracket E causes the cam C through its edge C to turn the arm H and place it under the tension of one arm of the spring G (see Fig. 5), which tension acts to snap the lug H over against the lug D as soon as the bracket E has been elevated sufficiently to clear the upper point of the cam edge C, and this takes place in practice when the member E engages the fixed stops 10. he lug D serves as a stop to prevent the spring G from throwing the lug H over and beyond the cam C and to insure the said lug dropping down on the upper edge of the cam plate when the cord J is released. The curtain has now been raised to its highest point and as soon as the operator releases the cord J, the curtain drops by gravity slight distance until the lug H rests upon the upper edge C of the cam plate 0, at which time the said lug is below the end of the lug D and is free to be forced laterally by the arm of the spring G, which is still under tension, until the lug H meets the projection C on the cam plate, against which it is forced by the tension of the spring arm. This position is represented in Fig. 6, and the curtain is thus held in its raised position. When it is desired to lower the curtain, it becomes necessary to first raise it, that is, until the lug H has .cleared the projection G at which time the right hand spring arm, viewing Figs. 4 to 6, has moved the lug H to its central posi tion on the other side of the projection C The lug H and the curtain are now free to be lowered, and on the downward movement of the curtain, the left hand spring arm is placed under tension by the cam plate '0, so that when the lug H reaches the lower end of the cam plate, it is moved laterally toward the right, viewing Fig. 4, so as to bring the lug H into position to again engage the edge. C of the cam plate on the neXt upward movement of the curtain.

From the above description, it will be seen, that when the curtain is left in its raised position, the lug H engages the transverse edge or upper wall C of the cam plate and is held under spring pressure a 'ainst the projection C so that in order to ower the curtain, it is first necessary to raise the same slightly before it can descend; that is, it is necessary to raise the curtain until the lug H clears the projection C on the cam plate. It will also be observed, that the cam plate 0 places the lug H under reverse spring tension on the downward movement of the curtain, so as to insure the said lug being restored to its normal position, that is, to a position in which it will engage the edge C on the upward movement of the curtain. In the present instance, the spring-actuated arm H is carried by the bracket E and moves with the curtain, while the cam plate C and its cooperating lug D are fixed to the plate or bar A, but I do not desire to limit my invention to this particular location of parts.

From the foregoing description, it will be readily seen that I have provided very novel means for raising and lowering the curtain roller, so that it can be readily dropped so that the room can be ventilated without raising the curtain.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1.
