SHADE-BRACKET.

SPECIFICATION forming part of Letters Patent No. 595,667, dated. December 14, 1897.

Application filed November 24, 1896. Serial No. 613,346. (No model.)

To coZZ whom it may concern:

Be it known that I, GEORGE BELL, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in a Combined Curtain and Shade Bracket and Shade-Actuating Device; 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 tomake and use the same.

This invention relates to a new and useful improvementin a combined curtain and shade bracket and shade-actuating device; and it consists in the construction and arrangement of parts hereinafter described, and definitely pointed out in the claims.

The aim and purpose of this invention are to construct a combined curtain and shade bracket and shade actuating device which can be secured to the ordinary corner-blocks of a window-casing or the casing itself without the aid of screws or other fastening devices and which can readily be removed therefrom. -With this object in view I construct the bracket of a plate of metal with movable inturned ends which are adapted to be forced in to grasp the sides of the corner-block or casing and an arm extending from the plate which supports the curtain-pole and shaderoller and shade-roller-actuating device.

It is also the object of this invention to construct a device which can be easily manufactured and at a slight cost.

These and other objects not hereinbefore specified are accomplished by the construction illustrated in the accompanying drawings, wherein like letters of reference indicate corresponding parts in the several views, and in which- Figure l is a perspective view of a windowcasing with my improved bracket applied thereto. Fig. 2 is a plan view of the bracket and shade-roller detached from the casing, showing the bracket which is provided with the shade-actuating device. Fig. 3 is a plan a view of a portion of the opposite bracket.

Fig. 4 is a section on the line 4 4, Fig. 2.

Fi 5 is a side elevation of the end portion of tile plate, showing the cam. Fig. 6 is a horizontal section through Fig. 5. Fig. 7 is a detail same.

view of the spring-casing and shaft; and Fig. 8 is a side elevation of the casing, parts being in section.

In the drawings,A designates the side pieces of a window-casing, and A the cross-piece.

B designates the ordinary corner-blocks at the upper corners of the casing.

O designates the plates of the brackets. As shown in Figs. 1 and 2, these plates consist of a single piece of metal. One end of these plates is bent inward, as shown at O, and is provided with points 0 for a purpose hereinafter described. The opposite ends of these plates are straight and are provided with sliding clamps D, which are provided with points D: Pivoted to the straight end of the plate is a cam J, which is pivoted to the plate by a screw J, which passes through an aperture J in the plate and is provided with a lever or handle J for actuating the The plate is provided with a series of apertures J in order that the cam may be adjusted laterally on the plate. This cam is adapted to bear against the sliding clamp D. The cam is provided with the serrated portion J to help hold the cam in position when forced up against the clamp. When it is desired to place the brackets on the blocks, the operator places the plate so that it will bear against the front face thereof and the ends 0 bear against the side and the points 0 impinge against the same. The cam is then turned, forcing up the clamp D and the points D against the opposite side of the block, thereby firmly holding the plate and bracket in place. It will be noticed that the plate can be readily secured in place without the aid of fastening devices and without defacing the blocks and can just as readily be removed therefrom.

To more readily withdraw the clamp D, I provide the same with a projection, preferably a small screw d, which engages a segmental groove d on the outer face of the cam. By this engagement when the cam is released it will draw out the clamp from the woodwork.

E E designate the arms extending outwardly from the plate. The inner ends are screw-threaded at E, as shown in Fig. 4, and are adapted to be, screwed in a socket E, which is slidingly secured on the plate 0.

The inner ends of the arms are adapted to be screwed up against the plate. By this construction the arms can be adjusted laterally on the plates to provide for different widths of curtains and windows. This is accomplished by simply unscrewing the arms E and E, so that the sockets can be slid on the plates until the proper adjustment of the arms is had, when the arms will be screwed into the sockets until their inner ends bear against the plate, as shown in Figs. 2 and 4, to firmly hold the parts in place. It will therefore be noticed that the arms also act as a set-screw.

G designates the shade-roller, upon which is secured the shade G in the usual manner. The opposite ends of the shade-roller are provided, respectively, with a squared and round aperture for a purpose hereinafter described.

I designates a casing which is journaled on the arm E by means of an axle K, which is rigidly secured to the casing. This axle passes through the arm E through a round aperture and is rotatably supported on the arm. The end of the axle is squared, as shown at 11, Figs. 2 and '7. This squared portion fits in the square aperture in the end of the shade-roller. The axle is provided with the annular flange H, which prevents the shaderoller from sliding too far on the axle and also keeps the axle from working oil the arm. The arm E is provided with an aperture, through which passes a pin h, which is provided with a rounded end h,which fits into the round aperture in the opposite end of the shade-roller. This pin is provided with an annular flange 7t, which holds the pin on the arm. It will thus be seen that the shaderoller is rotatably supported on the arm E by means of the pin 7L and will rotate with the axle K on the opposite arm E.

M designates a sleeve extending from the arm E and surrounding the axle K. This arm is provided with a rib M for a purpose hereinafter described.

N designates a coiled spring having one end secured to the casing and the opposite end secured to the arm E by means of a pin N. It will soon that the casing I is provided with flanges N, which will protect the spring N.

P designates gravity-pawls pivoted at P to the inner side of the casing 1", as shown in Fig. 8, and which are adapted to engage the rib M on the sleeve M. These pawls are prevented from flying up by turning down the flange of the casing, as shown at P in Fig. 8. The normal tendency of the spring is to raise the shade, which is prevented by the pawls engaging the rib M. \Vhen it is desired to lower the shade, the casing will be moved in the direction of the arrow, Fig. 8, and the pawls will ride over the rib until the shade has been lowered the required distance, when the pawls will engage the rib and hold the shade in its adjusted position. \Vhen it is desired to raise the shade, it is given a sudden downward movement, releasing the pawls, when the spring will raise it the required distance and until stopped by the operator, when the pawls will once more engage the rib and hold the shade stationary.

To the outer ends of the arms E E are secured the pole-holders F, which support the curtain-pole and curtain. (Not shown.)

R designates a brace depending from the arms and which are provided with the ornamental heads R, which rest against the cas ing and help to support the arms and bracket.

If desired, the bracket can be placed vertically on the block, as shown in dotted lines, Fig. 1, instead of horizontally, or any desired height on the casing by arranging the plate so that the points 0 willbear against the side and then pressing down the opposite end, so that the points D on the clamp will impinge slightly in the front smooth surface of the casing and then operate the cam, as before described.

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

1. A bracket for supporting curtain-poles or shade-rollers, consisting of a plate adapted to be secured to a Wl11 (l0\ "casing, a screwthreaded socket slidingly adj ustably secured on the plate passing through the socket, and an arm having its inner end adapted to bear against the plate and provided with a screwthreaded inner portion engaging the threads in the socket, the screw-threads so arranged that the inner end of the arm is adapted to be screwed up against the plate, whereby the arm acts as a set-screw for locking the arm and socket in their adjusted position, substantially as described.

2. A device for supporting a window-shade, consisting of a pair of brackets secured to a window-casin g, a shade-roller having one end rotatably supported on one bracket, a springcasing provided with an axle extending through the opposite bracket and rotatably supported thereon, the axle being secured to the roller and adapted to rotate therewith, a sleeve extending from the bracket surrounding the axle and formed with a rib on its outer surface, a spring having one end secured to the casing and the opposite end secured to the bracket, and a pawl on the casing adapted to engage the rib on the sleeve to lock the shade-roller and casing in their adj usted position, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE BELL.
