ADJUSTABLE SHADE-ROLLER;

from the room; to provide a construction in which the usual solid all wood roll is replaced by one of open construction so that in case of breakage or detachment of the operating spring or other injury, it may be repaired readily by any person, whereas now, said rolls are usually thrown away upon the slightest disarrangement of their parts, because they are all concealed and it is a diificult thing to get at the inter or;

to provide; a construction of this kind in which the usual spring operating and ratchet controlled mechanism can be employed so as to avoid increasing the ex-f vide improvements in the telescoping and supporting mechanism-of the roll; to provide an improved supporting bracket and an improved way ofconnecting it with the rod or roll; to provide an improved way of detachably connecting theshade with the roller, taking advantage of its skeleton character for that purpose to provide an improved curtain hanger and supporting connection. therewith; and to provideimprovements in the general construction and.

Specification of Letters Patent. Patented June Application filed October 9, 1919. Serial No. 329.526.

Fig. 4 is a transverse sectional view on the line 4,-4'of Fig. 1; 1

Fig. 5 is a side view of a modification, and Fig. 6 is an end view of the bracket shown in Fig. 5. v

The device is shown in the first four figures as mounted on a pair of brackets 10, each consisting of'a single separate piece of metal with two opposite flanges 11 pro-' jecting therefrom at right angles. Perforations are provided for theholding screws 12 which extend into the edge or end of the casing 13 so that they will not mar the front or exposed face of the woodwork.

The object of having two flanges 11 is simply to make the bracketright and left handed so that it can. go on either side of the framework, the outer flange 11 may not I be needed if this advantage is *not desired.

These brackets being secured in position, the two halves 14: and 15 of a-central telescoping. shaft are "fastened to these brackets in fixed position with respect thereto.v This is done by passing one end through a central perforation in each bracket and fastening the two shaft sections tothefbrackets'by means of screws 16 or It will be observed that these the like. two shaft sections 14 and 15 telescope with respect to each other so as to provide for any necessary adjustment and that they are fixed by their attachment to the brackets so as to be non-rotatable.

After :the telescoping shaft is adjusted to the proper length, it may be, and pre ferably is, fixed inithatposition by tightening up a screw 17 carried by a collar 18 which is otherwise loose on the tube 15. This tube has a perforation through it for permitting *the screw 17 to engage the surface of the othermember 14 of the telescoping shaft. Inthis way, the two parts Mounted on this telescopingfshaft are a plurality of rotatable disks '19 three being shown in the 'present instance. Each of these disks is free torotate independently but they are connected togetherby three telescoping rods 20, so as to formja skeleton framework. It-will be understood, of course, that-I am not limited to the number three,.but I find threeof these rods to be a most convenient number. Each of them together and constitute an consists of a small solid rod extending into a tubular or hollow one, so that they are capable of exactly the same adjustment as the central shaft 141-15 so as to accommodate window frames of any ordinary size.

The two end disks 19 are limited in motion inwardly by a collar 21 and a ratchet collar 22 which may rotate in contact with the brackets if desired. The ratchet collar 22 is the ordinary ratchet usually employed in shade rollers and gravity ratchet pawls 23 are shown for controlling the motion of the shade roller in the usual way. The usual operating spring 24 is connected in stationary position at one end by the collar 25 on the tubular shaft part 15 and is connected at the other end with the central disk 19. This spring thus operates to draw up the shade in the usual way.

On account of this skeleton construction, I am enabled toconnect the shade with the roller in a more convenient and practical manner than has been the case heretofore, and also to make the connection detachable. This is accomplished: by means of hooks 26 sewed or otherwise attached to the end fold or selvage of the shade and passing over one of the adjustable rods 20 as shown at the top of Fig. 1.

The two members 14 and 15' being stationary, I can employ that as a support for a curtain rod and for thatpurpose, I provide a pair of curtain rod hangers 80, each having a set screw extending through the wall of the same against the shaft 15 or 14 so as to hold the hangers 30 in any desired position. Each hanger is provided with a hook in the form of a-wire 33 extending up from it near the end. Each of these passes through a perforation in the end of oneof the two members 34- and 35, which telescope adjustable curtain rod. I 5

In addition to the use ofthe device as above specified, and-its mounting on the outside of a window casing, I have provided means whereby it may be mounted if desired on the inside of the casing andthis I have shown in the form of a pair of spaced projections 1 0 on the outer ends of the two members l liand 15. These projections are adapted'to entertwo segmental perforations 41 in'metal plates 4c2'screwed to the inside surfaces of the window casing 13. This holds the two. parts of the shaft in fixed position, it being understood that they will be securedtogether by means of screws 17.

This affords a device which is all open and can be put up, taken down, and repaired fering with the ordinary manufacture of the roller spring and ratchet arrangement which can be used with this invention;

Although I have illustrated and described a single form of the invention with only one modification, I am aware of the fact that support' for holdingand winding up the shade, and a-spring coiled on oneof said members and connected withtheframefor rotating it on the support.
