.SPIECIFICATJION- forming' part 0f Letters-Patent N0. 516,921, dated March 20, 1894,.

Application filed .Tuly 20, 1893. Serial No. 481,007. (No model.)

To @ZZ whom it may concern.-

Beit known that I, JOSEPH DARLING, of Baldwin, in the county of Butler and State of Pennsylvania, have invented a new and useful Improvement in Curtains, of which the following is a specilication.

My invention is an improvementin curtains and especially in the fixtures and the invention consists in the special construction, com binations and arrangements of parts as will be hereinafter described and pointed out in the claims.

In the drawings-Figure l is a perspective Vlew of my curtain as in use. Figs. 2 and 3 are detail views of the opposite ends'of the curtain and the'brackets at such ends. Figs. 4 and 5 are detail sectional views illustrating the ratchet guide, andY Figs. 6, 7 and 8 are de-y tails views.

The curtain A is fixed to the roller B which may be of the Hartshorn or other self rolling type.- At one end the roller B is journaled to the bracket C while its other end is fixed to the bracket D. The bracket C is suspended on a cord E and is formed with an inwardly projected arm C having at its extremity a pad or cushion C2 which bears against the wlndow frame and prevents any denting or marring thereof. This is important as the said bracket C is simply suspended by a cord and it with the connected end of the curtain lWill be blown away from the window by even a light breeze and will drop back and hammer against the window frame marring the same considerably in'a short time. This is avoided by furnishing the pad which cushionsI the blow and avoids injury to the Window frame.

The cord E extends up from the bracket C over a guidesF at one side of the top of the frame thence across to the opposite side of the frame and over a guidefand thence down and connects with a cord G. This cord G is wound on or around a guide H is carried thence up over the guide f and thence down and connected with the bracket D. The

other end of cord G extends up from guide H and is also connected with the bracket D the connection being preferably effected through the medium of the spring I which is shown as a coil spring and operates to give tension to the cord G. at all times and thus enable the certain operation of the curtain thereby. It will be understood that the curtain may be caused to ascend or descend by properlymanipulating the cord. To facilitate the lifting of the curtain I make the guide Hin the form of a ratchet drum with its ratchets so facedv that when the cord is moved to raise the curtain said ratchets will slip while if moved in the opposite direction, that is to lower the curtain it will lock the rachet from turning so that the downward movement ofthe curtain is retarded by the friction of the cord upon the guide H. This will be best understood from Figs. 4 and 5. If moved in the direction indicated in Fig. 4 the ratchet will lock the guide from turning so the cord -must beslipped along the guide, while if the cord be moved in the direction indicated in Fig.5 it will be seen that the ratchet will slip, the guide thus rolling and permitting the curtain to be easily raised while the weight ot' the curtain and fixture aids in lowering the same.

The bracket D is of special construction vbeing formed with the main plate l having at its outer end the forwardly projected lug 2 having the seat 3 for the angular stud of the roller and having at its inner end the upper and lower arms 4 and 5 which project up and down approximately at right angles to the plate l and the operating cord is connected with said arms 4 and 5 near their extremities.

This construction and arrangement is important for several reasons. It permits by reason of the plate l the'extension of the curtain outwardly beyond the operating cords and permits it to be made to fully cover the window. Another advantage resulting from this construction is that the arrangement of the plate l and arms 4 and 5 constitutes practically a double bell crank lever enabling the operating cord to exert leverage to sustain the bracket and curtain in position.

The curtain is secured rigidly in its seat in the bracketD by means of the spring pawl latch I which is fixed at one end t' to the bracket and projects at its other end partly over the outer endor side of the seat 8.

It will be seen that if the square end of the curtain roller be inserted inl said seat 3 from the inner side of the bracket it will be locked firmly by the point of the springlatch IOO operating like a pawl against the side of the stud as will be best understood from Figs. 6 and 7. The square stud can however be conveniently released by slipping the point of a screw driver or other suitable instrument under the free end of the pawl and pressing the same outward clear of engagement with the roller stud.

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

l. An improvement in curtain hangers consisting of the curtain, the cords on which said curtain is suspended and aratchet guide around which the operating cord is passed without being fixed to it and from which the cord extends whereby said guide will turn in one direction of movement of the cord but will lock during the opposite movement of the cord and require the cord to slide upon it during such movement all substantially as set forth and for the purposes specified.

2. A curtain bracket provided with a seat for the roller stud and having a pawl latch fixed at one end and projected at its opposite end adjacent to said seat whereby to engage the side of and lock the roller stud from endwise movement out of its seat all substantially as and for the purposes set forth.

3. A curtain bracket composed of the main plate having at its outer end a forwardly projecting lug provided with a seat for the roller stud and with devices for locking such stud in said seat, the main plate being provided at its opposite or inner end with arms projecting up and down at approximately right angles to the main plate and adapted for the connectionof the cord lengths allsubstantially as and for the purposes set forth.

4. A curtain bracket consisting of the main plate having at its inner end upwardly and downwardly projecting arms and provided at its outer end with a forwardly projected lug having a seat for the roller stud and a latch pawl fixed at one end and projecting at its other or free end partly over the seat in the lug whereby to engage the side of the stud all substantially as set forth.

5. The combination with the roller the operating cords and the guides of the bracket having a main plate provided at its inner end with upwardly and downwardly projecting arms, to which the operating cord isconnected, and having at its outer end a forwardly projected lug having a seat for the roller stud and devices for locking such stud in said seat all substantially as set forth.

6. A curtain bracket substantially as described provided with alug having an opening forming a seat for the roller stud and provided along the outer side of said lug with aspring plate xed at one end and having its other end free and arranged and adapted to engage the side of the stud, all substantially as described, whereby the stud may be inserted through its bearing opening past the point of the spring plate but will be locked against detachment by the pawl action of said plate, as and for the purposes set forth.
