iMPROVEMENT IN BRACKETS FCR SUSPENDING WINDOW-SHADE RLLE'RS.

Specicaton forming part of Letters Patent No. 146,385, dated January 13, 1874 application filed March 3, 1873.

To alt whom it may concer-n:

. 'Be it known that I, ALFRED S. DreKrNsoN, of the city of Brooklyn, in the county of Kings and State of New York, have invented certain Improvements in Brackets for Suspending.

Window-Shade Rollers, of which the following is a specification: i

M y invention relates to new an d useful brackets, which are made in such a manner that they can be safely secured to the ends of windowshade rollers, and for the purpose of suspending rollers and shades on or over windows, that they may be raised and lowered with safety, and, for Ventilating purposes, they have. an opening, through which the cords are secured, by which the roller and shade are suspended, one `bracket being secured at each end of the roller, which are designed as a pair for each roller. They are provided with a lateral proj ection or horn to guide the position of the roller and stop the slat or bar in the end of the shade from passing over the roller between the horn.

By these means the usual cross-bar, made of wood and combining the brackets, and the labor ot adjusting` its length and securing the same to the brackets and roller, are dispensed with.

In the annexed drawings, Figure l represents a front elevation of the shade, the roller and i brackets shown dissected, andthe brackets con;-

is a detached vertical cross-section of the roller' and the bracket to which the spring-shaft is attaohed. Fig. 4 is a longitudinal vertical section of the same. Fig. 5 is a detached face view of the bracket on the ri ght-hand end of' the roller, as shown `in Fig. 6 5 Fig. 6, a vertical longitudiual section of the same attach ed to the respecty Fig. 7 is a-perspective view of the left-hand bracket attached to the spring-shaft, as shown in Fig. 4.

.A represents the shadecloth, which has its loose end below the usual bar B. C is the roller upon which the shade winds. It is provided with the spring D and shaft E for winding the shade up, and with the usual pawls F F and notches Gr Gr on the said shaft for stopping the roller. H represents the plate on the end of the roller to which the pawls F are at` the shade and roller are raised and lowered;

K, the cord on the center of the bar at the end ot the shade, for guiding it on the roller. L is the cord-stop for the cord J, and M M are the guide-pulleys on each side of the casing at the top ot the window, over which the suspensioncords I I are passed. N represents the bracket attached to the shaft E, and O the bracket on the right or wood end of the roller. These two brackets have each a lateral projection or horn, l, which extend facing inward and a short distance from the roller and shade. Their ends terminate with a point, and their lower edge is .t

They are sufficiently close to the roller to prcvent the bar B from passing between, and permittin g the shade to unwind when rolled up, as shown in Fig. 3. The bracket N is secured on the lat end of the 1shaft E, and has, for that purpose, a taper flat opening, Q, with the small openin g toward the roller, and isprovided with a set-screw, It, and the pin V. The edge of the shaft E is notched with a le to tit the taper groove in the opening Q. The opposite orlower edge may be led for the set-screw R to rest in, and, by placing the roller-shaft E into the opening Q and turning up the set-screw R, presses the shaft tightly in the bracket hole Q and secures the shaft end of the roller C to the bracket end, as shown in Fig. 6. `The roller maybe provided with a metal plate, T, secured to the end with nails or screws to prevent the screw S from getting loose, `Eachibracket has near its upper extremity a hole, in which the suspension-cords I are secured. Oversaid hole they have a grooved projectioinU, toward the roller ends, for the purpose of4 guiding `the cords I` upward and over from either side of the pulleys* M M, and down, and secured bythe cords J to the cord-stop L, which holds and suspends the roller and shade, as shown.` The cords may The screw-head prevents the P P'may be east on them lower down, opposite be placed through the hole from either side of' the brackets, and pass upward or rest in the groove in one or both brackets at the same time, in order to suspend the roller and shade by the cord J, secured to the-stop L on either side of the Windowcasing, as the ease may be. In order to have the pawls F lock readily in the Shaft E When rolling the shade up, I make the bracket N crooked, and make the hole for securing the cord I to 'recede toward the window-casing in Va Vertical line from the shaft-Y hole Q, asshown. By these means the bracket and roller are kept from twistin g or bein g turned outward by the stiffness of the spring` in the roller, or the Weight of the latter, and, being` suspended off a direct line by t-he cord I, the roller is kept down in position for the pawls to lock on the shaft and stop the roller and shade from Winding up when desired. rIhe brackets N and O I make to pair, and in different sizes to it roller ends now in general use. The horns or below the roller, or placed on the bracket at l any point desired. In applying them to coinmon or ordinary roller ends for suspending, the bracket O is employed, one at each end of the roller, in same manner as shown in Figl.

What I claim as my invention, and desire to secure by Letters Paten t, is-

l. The brackets N and O, provided with the horns P P and grooved projections U U, sub stantia-lly as and for the purpose herein described.

2. The bracket N,Wi th the horn P, the grooved projection U, the hole for the cord I, the opening1 Q, setscreW R, and the pin V, all combined substantially as and for the purpose set forth.

3. The brackets N and O, with the horns P P and the grooved projections U U,'in combi-Y nation with the cords I I, the shaft E, and screw S, with the roller C, substantially as and for the purpose herein set forth.
