WINDOW-SHADE ADJUsTI-:R-

SPECIFICATION forming part of Letters Patent No. 790,703, dated May 23, 19.05.

Application filed February 14, 1905. Serial No. 245 ,564.

To LZZ whom, 2125 may concern: v

Be it known that l, WILLIAM C. ORGAN, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Window-Shade Adjusters, of which the following is a specification.

My invention relates to a means for adjusting window-shades with relation to thewindows to which they are attached so that such shades may be bodily raised or loweredwvitli relation to the window-opening andby such movements either placed at the top of the window or at some point intermediate of its height and independentof the rolling and unrolling of the shade.

My invention consists in tubular guides fixed to the lower part of the window-frame and rods slidable in said guides connected together at the top and having sockets for the reception of the pivot and non-turnable pins, respectively, of what are known as spring shade-rollers.

My invention comprises details of construction, which will be more fully explained by reference to the accompanying drawings, in which- Figure lis a perspective View of my invention. Fig. 2 is a section of one end of the shade-roller and the socket-piece.

Various devices have been employed by which shade-rollers may be placed at different heights with relation to the window-opening, the object being to provide for the entire cutting oif of the light when the shade is unrolled from the top of the window or for the admission of light above the shade when the roller has been lowered below the top of the window.

My invention is designed to provide animproved and easily-adjustable device for this purpose which is especially applicable to spring shade-rollers.

As shown in the drawings, A i`s a windowframe of any description.

2 represents Vertical tubes fixed to the casing at any desired point with relation to the moving sashes. These tubes are preferably fixed inside of the inside stops and may extend from the bottom upward to one-half or less of the height of the window-opening. Within these tubes rods 3 are slidable, and upon the upper ends of the rods are fixed the blocks or end pieces 4. These blocks 4 are here shown as connected by a rod 5, which may have right and left screw-threads at its opposite ends and may thus bescrewed into the blocks, the screw-threads terminating in shoulders which will limit the distance to which the rod is screwed, so that the rods 3 will stand parallel and slide freely within the guide-tubes 2. Below vthe rod 5 openings are made in the faces of the blocks 4. One of these openingsis cylindrical and is adapted Yto receive the pivot-pin 6 of the shade-roller ingly flattened or rectangular opening in the block 4'at that end, so that the shaft to which the spring is fixed is held stationary, while the roller is turnable upon it.

The shade 9 has the usual cord or chain 10 fixed to its lower bar, so that it may be pulled down by the chain, and is held at any point of adjustment by the pawls usual to this class of shade.

11 is a cord having one end connected with the center of the bar 5, passing up over a pulley 12 and thence down, and having at its end a ring or other connection, as at 13, by which the cord may be operated. The pulley 12 is of that class having a notch in one side and adapted to bind upon the cord and hold it at any point when the cord is drawn out of line and to one side of the pulley. By means of this cord it` will be seen that the bar 5, with the sliding rods, and the heads' 4, in which the shade is journaled, may be raised to the top of the window, and when at this point the shade may be pulled down to exclude all the light` or the rod may be lowered until the top of the shade is at any desired point above the ends of the guide-tubes 2, and theshade may thus be suspended at any desired point between the top of the window and ,the upper ends of the guide-tubes. Thus when the shade IOO is in this position by pulling it down the light would be excluded to any extent from the lower part of the window` while any desired amount of light may be allowed to enter from the top of the shade.

The device is easily applied to windows and is very simple and effective for the purpose desired.

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

1. The combination with a window or like frame of fixed tubular vertical guides, rods slidable in said guides having heads upon the upper ends, a shade-roller having its bearings in said heads, a pulley fixed at the top of the window-frame, and means whereby the heads and the shade may be raised or lowered with relation to the window-opening.

2. A shade-roller attachment for windows consisting of vertical tubular guides fixed upon each side of the lower part of the windowframe, rods slidable in said guides having heads at the upper end, a connecting-bar by which said heads are united, a cord having one end centrally attached to said bar, a locking-pulley in the top of the window-frame over which said cord passes whereby the slidable frame may be raised lowered and iixed at any point, and a shade-roller having bearings in the heads of the sliding bars below the transverse connecting-bar.

3. A shade-roller attachment for windows consisting of vertical tu bular guides lixed upon each side 0f the window-easing` a frame consisting of two vertical rods slidable in said tubes having a transverse connecting-bar at the top, a shade-roller having its ends supported in said frame below the transverse bar, a cord centrally connected with the bar, a locking-pulley fixed to the top of the windowcasing over which said cord passes, and an attachment at the opposite end of the cord by which the shade-carrying frame may be raised or depressed.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
