to provide a practicable-means for permitting a shade roller tobe brought bodily to any desired position below thetop of a window, whereby the shade can be caused to cover any desired portion ofthe window, either at the top or bottom or part way between.

The invention also involves improved means whereby, the roller can be rotated and raised and lowered in such a way as to be controlled by the manipulation of the shade itself, so that byraising and lowering the shade in a certain manner the shade can either be rolled up on the roller or the raised or lowered bodily.

The invention also involves improvements in the details of the supporting and guiding a means for the shade roller, and in the means for controlling the rotation andreciprocation thereof and in other features of con- Further objects and advantages of the invention will appear hereinafter. i

side casings. It is shown as applied to a box casing. As illustrated the side casings 10 are provided with a pair of opposite cylindrical sockets 11 for receiving cylindrical casings 12. These casings have soldered to the inner end thereof a flat projection 9 extending into the wood and secured by screws 8. Each of these casings is provided with a drum 13 on which is wound a flexible 'connectionli shown in the form of a metallic tape, but it will be obvious that any other desired flexible connection can be used. Inside the drum and so wound up that when free to operate it will rotate the drum in a direction to entirely wind up the flexible connection thereon is a coiled spring 15. This is fixed atone end to the drum and at the other to the stationary shaft 16. On the back of this drum is a one-toothed ratchet wheel 17 rotating with the drum and having a flat surface 18 adjacent to the tooth 19 thereof. A gravity pawl 20 is shown fixed on the casing 12 in such position that as the drum with the ratchet wheel is rotated in the direction of the arrow in Fig. 8

at a slow speed, the pawl will be caused to catch in the tooth 19 at every revolution so that the fie rible connection will be stopped at definite points. However, if the device is manipulated so as to permit the spring to rotate the drum and wheel rapidly the surface 18 willgive the pawl a throw over the tooth .19 so that the drunr will continue to rotate. and the flexible connection will conis well-known in shade rollers proper. It will be understood, of course, that both of these devices are designed in the same way but that they .are'right and left handed. However they are so designed thatthey will both. catch at the same time when the two flexible connections are raised together as they are designed to be. i

The I only thing required. is that this spring shall slotsorguides23 and 24 respectively, shown as being located in the casing. The holder 21 is provided with a non-cylindrical slot 25 therethrough for a non-cylindrical spindle 26,0f a shaderoller 2'7.v Thisshade roller is be weaker than the springs 15, a matter that is controlled, of course, in the selection of the latter. The holder 22 is provided with a cylindrical passage for a cylindrical spindle 31 of the shade roller. 'Both of these holders are provided with side flangeswhich operate in the undercut guides, as will be obvious, to keep them therein. The spindle 31 is provided with a non-circular portion 32 driven into the wood of the roller to hold it rigidly therein, the purpose of which will appear hereinafter.

The outer end of the spindle 31 is provided with a diametrical open ended slot 33, This is to receive an e'dgewise movable bar 34 as indicated in Fig. 4-, This bar is mounted to bear at its ends on pair of spring members 35 and .lS'IlOlT- m'ally forced into the dotted lined position in F 5 by theseand a spring 36 on a screw 3'7, secured to the bar in offset position. :By

screwing up a wing nut 38 on the screw,

however,- these. parts can be brought up to v he full line position in Figs. 4 and 5. The bar is" guided by pins 39 passing through transverse slots l0 in the ends of thebars. In operatiorni let it be assumed that the parts are inthe position shown in Fig.2,

withthe pawls 20 located against the teeth 19' so as to hold-the shade roller in position.

the bar 34 is in the full line position, Figs. 2, l and 5,;it is obvious that it will 'prevent the rotation of the spindle 31 and consequently of the shade roller itselt. This is whythe projection 32 is provided Now it will be obvious that a pull on the shade cannotunwind the shade on its own roller, but will simply result in lowering the roller as a whole along the guides. Thisis done in a way that will be readily understood, .the pawls 2O controlling the position at which the roller is left Now if it is desired to raise or lower the Shade on its roller without moving the roller, the bar 343 is.

moved out, of' the slot 33 by loosening the wing. nut 38 and allowing the springs to force it backQ When this is accomplished and the bar is in the. dotted lineposition the manipulation of the shade will have the usual ellect in raising and lowering it due to the ordinary spring-ratchet in the shade roller',,a:nd it canhave no'efl ect to raise and lower the shade roller because the spring in will be i seen therefore, that the manipulat on of the device is extremely simple and that it is a. very. easy matter to bring the shade toany desired pos tion so as to cover any desired portion, of the window and yet there arev few parts which are likely to get.

2. The combination of a shade roller spindle having a slot, abar having a thin edge for entering the slot in the shade roller spindle, s aringl's for pushing said bar away from the spindle, and a screw and nut for moving it in opposition to the springs.

3. The combination of a casing having a vertical slot therein, undercut along both sides and having acylindrical socket at the top, a: holder slidable in the undercut portion of the slot, a cylindrical casing mounted in said socket, having a flat projection thereon extending into'the wood of the casing to keep it stationary, a winding drum in the cylindrical casing having means for raising said holder, and a shade roller having a spindle supported by theholder.

L- In a shade roller device, the -combination of a vertically movable pair oi holders for the ends of a shade roller, yielding means for elevating said holders, a shade roller having a springratchet, device by which the roller can be held from rotating,

In a shade roller device, the combination of a vertically movable shade roller adapted to be held at different elevations, said shade roller having means whereby the shade thereon can be wound on and off the roller and held in difierent' positions with Copies of this patent may be obtained for respect thereto, a spindle on the roller having an open ended slot in the end thereof,

a bar movable edgewise into said slot, re-

an open ended slot in the end thereof, and

means for entering said slot to prevent the rotation of they roller.
