Specification of Letters Patent.

Patented Feb. e, 1906.

Application filed September 26, 1905. Serial No- 280,l 14..

To all whoin it may concern:

Be it known that I, EMMA M. RUFF, a citizen of the United State s, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new, and useful Improvements in Window-Shade Brackets; 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 tov which it appertains to make andu'se the same.

For shade-rollers of the type known as spring-rollers I have produced supportingbrackets of novelconstruction'having special r5 adaptation which permits the brackets to be fixed in any desired position in the window and the rollersubsequently i noun'ted in the brackets. This is the usual way with brackets of the ordinary shade-rollers; but so far as I know and can find no brackets have been produced that will allow the pair to be fixed preparatory to mounting the spring roller shade in which an angleug is mounted in a slotted bracket to control the action of the roller-sprin and in the claims appended hereto I wil point out in connection with the accompanying drawings the precise construction which constitutes my improvement.

Referrin 'to the drawings, Figure 1 shows 0 a portion of the spring-roller and its an le-lug and pin-bearings, the slotted bracket or the angle-lug and the bracket for the bearing-pin having a airlof holes to suit the adjustment of the rol er in the. difierentslots of the slot- 5 ted bracket,'tl1e brackets being in depending positions. Fig. 2 is an identical view showing the brackets in reversed positions. Fig.

3 shows the slotted bracket in a horizontal" position. i

In Figs. 1 and 2 the roller-lug and pin are in the positions they respectively occupy in alinement with the slot and the hole of the brackets when the roller is mounted, the

o en-ended slot being provided for changing 4,5 t e mountin of the roller to suit different positions of the brackets. Each bracket is .a plate of suitable len th and has an enlarged 'end, he other end 0? each terminating in an attaching-screw. The bracket for the angle- 5o lug of the'roller has a plurality of intersecting slots, one of which is open at the edge of the bracket, and the bracket for the revolving pin has a pair of holes, and the relation of the slots and the holes for the adjustment of 5 5 the roll-supports I will .now describe Referring to the slotted bracket, the slot 1 stands radial to the center of the bracket and opens at the .edge of the plate where its en; larged. end joins the edge of the shank 2. This open slot terminates in a recess 3 standing towardthe enlarged end of the bracket, and also into a slot 4, standing about in alinementwith the'recess and inchned toward the shanl while a slot 5, in alinement with the 0 en slot, stands toward the enlarged end of tlEe bracket, the slots and the recess intersecting in an opening about the center of the enlarged end of fh'e bracket, and these slots by reason of the-advanta e of the open slot and. the recess allow the bracket to be fixed in three different positions. The changin of the angle-lu 6 from one slot to the ot er. will necessari y change the center of the angle-lug in relation to the'center of the revolving bearing-pin 7 in the other bracket, and to maintain the alinement of thetwo centers in the dilierent positions of the brackets I provide the bracket of the revolving pin' with a pair of holes 8 9, so that in changing the angle-lug in the slots the revolving pin will be also changed in the holeto support the pin in alinement with the center of the angle-lug, and thereby cause the roller to run true and even, and for this purpose it will be noticed that the hole 8 is in the center of the bracket and the other hole 9 is eccentric to said center, being so placed that its center will coincide with the center of the angle-lug when it is chan ed into the slot 4, wlnle the center hole 8 wi l coincide with-the center of the angle-1n when placed in the other slot 5. It will there ore be understood that in setting the angle-lug in the slot 5 the pin at the other end of the roller will be set in the centerhole f its bracket, and in setting the angle-lug in the otherslot 4 the revolving pin must be set in the eccentric hole 9, so that the center of the bearings ofthe roller will always be in alinement.

In the position of the bracket as a hanger, as in Fig. 1, the angle-lug will be inserted into and through the 0 en slot to its seat in seated in the same slot 5, while in the position of the bracket seen in Fig. 2 the angle in will be passed into the slot 4, and to pernut this adjustment of the angle-lu the recess 3 is provided to allow the angleug to be turned from the 0 en slot first into the recess and then-intpf its e'aring in the slot 4, and

this way the open-ended slot and the recess form the means whereby the roller is mounted in the brackets after they have been fixed in their proper positions in the frame.

It will be understood that in whatever position the bracket for the angle-lug is placed the open-ended slot will always stand in a position opposite the pulling force of the shade upon the roller and will always tend to bind antl hold the lug in its proper slot. The dotted lines indicate the shade upon the roller and the arrows the direction of the winding of the shade. Figs. 1 and 2 illustrate how easy it is to mount the spring-roller after the brackets have been fixed by inserting the angle-lug in the open-ended slot of the slotted bracket.

I-claiin l. A bracket ""Jr a shadeaoller, consisting of a plate enlarged at one end, its other end terminating in an attaching-screw, said enlarged end having a central slot open at one end, a slot eccentric to the center slot cornniunicating at right angles with its open end, a recess communicating at right angles with said'open end at the other side of the central slot, and an open slot communicating with the eccentric slotand the recess in alinernent with the central slot, for, the purpose stated.

2. A bracket for shade-roller, consisting of a plate enlarged at one end, its other end terminating in an attaching-screw, said enlarged end having a central slot open at one end, a slot eccentric to the center slot cornrnunicating at right angles with its open end at one side, a recess communicating with said open end at right angles to the other side of said central slot, and. an open slot conirnuni-L eating with the eccentric slot and said recess in alinernent with the central slot, in combination with a companion bracket having a pair of openings one central and the other eccentric thereto, for the purpose stated.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
