" To -aZZ whom it may concern UNITED STATES,

PATE P I Ew V JClHNf E. menswear :onm'd a, iEunsYLvnnrn SHADE-ROLLER surronr."

- Be it known that I, JOHN E. MOCLOSKEY, a citizen of the United States, residing at Johnsjtown, in the county of Cambri a and State of- Pennsylvania, have invented certain new and useful Improvements in shade Roller Supports, of a specification.

The present invention re roller support, and has for its "object to provide a device of this character which em bodies novel features of construction whereby the shade roller is adjustably mounted and can be positioned at any desired point in the height of the window casing, thereby providing for lighting and ventilating the room in the most effective manner.

Further objects of the invention are to provide a device of this characte-rwhichliscomparatively simple and inexpensive in its construction, which enables the shade roller to be bodily elevated orlowered upon the window casing and quickly positioned at any desired height thereon, and which'can be readily mounted upon any window casing and arranged to receive any length or size of shade roller. 7 i

With these and other objects in view, the invention consists in certain combinations,

as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the inventionsuspended bracket for supporting the same.

Fig. 4 is a transverse sectional view through one end of the upper spring roller, showing a detent means for locking the upper spring roller against movement after the shade roller has been adjusted and positioned at the proper elevation.

. Fig.5 is a sectional view taken at right angles to the view shown in Fig. 4.

Corresponding and like parts are referred to in the following description and indicated which the following is lates to a shade roller 1.

Application filed January 10, 1920.- Serial at. 350,501. 1

is-an' upper spring roller-1 which has the ends thereof received and housed within hollow casings 2, and said casings having flanged bases 3wh1ch are permanently secured to thewindow casing by suitable fastening members such as screws. ends of these hollow casings 2 are prefer- The outer ably closed and formed with suitable openings to receive the end studs 4 of the spring Flexible cords 5 extend through openings 6 in thecasings 2 and have the upper extremi'ties thereof wound upon the respective end portions of the upper spring roller -1, while the lower extremities thereof are securedto suspended bracket plates 7. These bracket plates are formed in rights and lofts, as is usual, and are suitably slotted'or perforated as indicated at 8, to receive the studs 9 of the spring acting roller 10 upon which the shade 1 1 is mounted. v I

With this arrangement of the parts it will be obvious that'the shade roller '10 and bracket plates 7 are suspended. from the upper spring rolleril by means of the flexible cords 5.," so that by suitably manipulating the upper spring roller 1 to wind the cords'*5 thereon, or unwind the" said 'cords therefrom, the shade rollar can be bodily raised ,or lowered for the purpose of positioning it at any desired elevation upon the window casing. The shade 11 itself can. of course, be rolled upon the shade roller 10 or unrolled therefrom in the usual manner. Provision is thus'made for positioning and adjusting the shade roller in such a manner as to light and ventilate the room to the best possible advantage.

In Fig. 4 I have illustrated a detent arrangeinent which may be employed for the purpose of locking the upper spring roller this detent is used it will be possible at all times to adjust the shade 11 on the roller 10 by the customary pulling and releasing of the shade, without danger of simultaneously bringing the upper springroller 1 into ac- 7 tion.' According to this construction one end of the upper spring roller 1 is provided with a notched disk 12 which is adapted to be engaged by the nose of a detent 14. The detent may, as shown, extend over the top of the casing 2 and be arranged so that the nose will extend downwardly into the casing through an opening in the top thereof. The detent is pivoted at 15 and is-adapted to be swung upwardly into inoperative position, although it is normally held in an operative position by a spring 16. A releasing lever 17 is shown as arranged within the casing 2 and is pivotally mounted between its ends between a pair of ears 18 projecting at one side of the window casing A so that it can be readily grasped when it is desired to release the detent 14 and change the position of the suspended shade roller 10. It will be obvious that the spring 16 will normally hold the detent 14 in engagement with the notched disk 12 and thereby lock the upper spring roller 1 against action, although a pull, upon the cord 20 will rock the releasing lever 17 upon its pivotal support and cause the arm 19 thereof to swing the detent 14 upwardly and out of engagement with the disk 12, whereupon the upper spring roller can function in the usual manner.

In carrying out the invention I'prefer to employ a connecting rod 21 connecting the two supporting plates 7, and said rod not only functions to connect these plates but also serves as a stop for preventing the shade from completely unwinding or releasing ofthe spring tension. The plates 7 may be provided at their edges with cord openings 22, and -as a further detail the roller 1 may be provided with a grooved sleeve or corrugated surface 23 toinsure the proper winding of the supporting cords thereupon. I

Having thus described my invention what I claim as new is:

1. A device of the character described,

ports for the same, a detent for locking thespring roller against action, adetent releasing lever provided with an arm adaptedto engage the detent to move-.it into lnopera tive position, means operable from below for moving the releasing lever, a lower shade'roller, and bracket plates suspended by the before mentioned cords and supporting the shade roller.

3. A device vof the character described, including an upper spring roller, fixedly mounted casings receiving-the ends of the,

upper spring roller, cords'connected to the ends. of the spring roller, a lower shade roller, bracket plates suspendedby the before mentioned cords and supporting the .shade roller, a detent mounted upon one of the before mentioned casings, means cooperating therewith to, lock the upper spring roller against action, a detent releasing lever mounted upon the said casing at a point between its ends, one end thereof being formed with an arm which is adapted to engage the detent to move the latter into inoperative position, and a pull member connected to the other end of the lever for operating the same. i

4. A device of the character described,

including an upper spring roller, fixedly.

mounted hollow casings receiving the ends of the upper spring roller and housing the.

same, said casings being formed with guide openings, cords connected to the ends of the spring roller and extending loosely through the guide openings of the casings, a lower shade roller, means carried bythe cords for engaging and supporting the lower shade roller, said cords being adapted to be wound upon the upper springroller and the portions of the roller upon which the cords are wound being completely housed by the casings, means for locking the upper roller against rotation in either direction, and

means operable from below for releasing the upper spring roller.

In testimony whereof I aflix my signature. JOHN E. MOCLOSKEY.
