JAMES V. WASHIBURNE, OF FULTON, NEW YORK.

SHADE-ROLLER.

- Application filed July 19, 1911, Serial No. 639,375.

To all whom it may concern:

Be it known that I, JAMES V. Wasn- BURNE, of Fulton, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Shade Rollers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improve. ments in shade rollers of the class set forth; in. my pending application #543,229 filed February 11, 1910 in which the roller is.

hollow throughout a portion of its length for receiving a centrally disposed spindle having a spear at one end adapted to interlock with a suitable bracket for holding the spindle stationary during the operation of the roller by or against the action of a suitable retracting spring which is coiled around the spindle and has one end secured.

thereto and its other end secured to a suitable disk on the end of the roller adjacent the spear.

The roller and spindle are usually made of cold rolled steel having a reduced end provided with fins driven into one end of the spindle to lock the two elements together, the intermediate portion of the spear having a circular bearing upon which the catch carrying disk is journaled and therefore the spear performs the quadruple func-; tions of supporting one end of the spindle,

holding said spindle stationary against rotation; forming a bearing for the catch carrying plate for holding the roller concentric with the spindle and permitting it to. rotate, and also serving as a clutch sectionf cooperating with the catch plates to hold the:

Renewed October 28, 1912. Serial No. 728,245.

when the spring is tensioned axially,'as, for example, when attaching it to the spindle I and to the disk, the central portion of the end helix of the spring within the channel or groove tends to rock toward the catch plates to such an extent as to sometimes in-- terfere with the operation of said plates, and the main object of my present invention is to obviate this difficulty. by forming. two substantially quadri-circular channels and leaving the intervening bridge between their ends so that the adjacent arched portion of the helix will have innerand outer bearings and thereby be held against tiltingvm'ovement relatively to the disk. l i

It is sometimes desirableto place the curtain roll at the bottom of the window frame to enable the curtain to beunrolled from the bottom upward in -which case it -may be necessary to lock thevcatch plates in their open positions soas not to interlock with the shoulders on the spear.

Another object of my present invention is to provide means whereby the same roller may be operated'either from the bottom or top of the window.

Other objects and uses will be brought out in thefollowing description. I

In the dra'wingsFigure 1 is an enlarged longitudinal sectional view of a'portion of a curtain roller embodying the various features of my invention. Fig. 2 is an outer end face view of the detached catch carrying disk and catch plates thereon, showing the catch plates as locked in their open positions] tional view of the same disk taken on line Fig. 3 is a transverse vertical sec-' 33, Fig. 2. Fig. 4 is an outer end face view of the detached catch carrying disk, the catch plates being removed to show the spring thereto. Fig. 5 is an inner end face view of the same disk showing the adjacent portion of the spring attached thereto. Fig. 6 is a plan of the blank for forming the catch carrying disk. Fig. 7 is an enlarged sectional view of the catch carrying plate through the channels as developed in a straight line.

In illustrating my invention I have shown 90 manner of connecting the adj acent end of the a "portion of a roller 1 having a central circular chamber 2 extending some distance inwardly from one end for receiving a spindle 3. This spindle is also provided with a central lengthwise socket 4 opening from one end in which is tightly driven the reduced end of a spear -5 having a series of radially projecting fins to firmly lock the spear and spindle to each other against relative rotation. The outer end of the spear extends some distance be yond the adjacent end of the spindle --3 and is provided with a flattened portion for engagement with a suitable bracket not shown to hold the spindle 3 against rotation. The intermediate portion of the spear 5 between the flattened end 7 and adjacent end of the spindle 3 is preferably circular and of greater diameter than the portion which enters said spindle and is provided with a plurality of, in this instance two, grooves 8 and a circular bearing 9-' just at the inner end of the grooves, said grooves forming shoulders adapted to be engaged by a corresponding number of radially movable catch plates .10 presently described.

Acne-piece catch carrying disk 11 shown in its developed form in Fig. 6 is adapted to be secured to the spear end of the roller.1 to form a bearing for said roller upon the journal 9 of the spear and is also provided with means for interlocking engagement with the adjacent end of acoiled spring 12 and in addition to these functions is provided with means for receiving and retaining the catch plates .10 in operative position. For these purposes the central portion of the disk is pressed laterally beyond the plane of the main body to form a circular hub 13 journaled upon the bearing 9, while the margin of the disk is provided with a plural-ityof, in this instance four, lugs or ears 14 preferably arranged at the four corners of a rectangle and deflected or bent laterally in the same direction as the hub 13 for entering corresponding recesses or grooves in the periphery of the adjacent end of the roller 2 to lock the disk and roller against relative rotation and at the same time 'holdin this end of the roller concentric with the axis of the spindle 3 and spear Two of the diametrically opposite sides of the disk 11- are provided with similarly formed wings or flanges 15 Which are bent at substantially right angles to the main body in a direction opposite to that of thehub 13' and lugs .14 and the outer edge of each flange or wing is pro Vided with a plurality of,,in this instance three, tongues IGQ, preferably spaced equi-distant apart and bent inwardly towardthe axis but apart from themain body of the disk so as to form intervening guide grooves for the reception of the adjacent edges of the catch plates l0. The remaining diametrically opposite sides of the disk -11 are provided with laterally projecting wings or flanges 17 which are bent outwardly at right angles to the main body of the disk or in the same direction as the flanges -15- to form suitable stops for limiting the outward sliding movement of the catch plates 10. These catch plates are somewhat similar to those in my pending application referred to and consist of similar flat sheet metal sections mounted upon the disk -1l in the manner described at opposite sides of the spear in the transverse plane of the grooves 8 and are provided on their inner edges with shoulders 18- reversely arranged for engagement with said grooves in the usual manner when used in connection with an overhead curtain roll. On the other hand when it is desired to position the curtain roll at the bottom of the window, the operation of these catch plates is undesirable and in order that they may be held in their open positions, the central tongues -16 may be bent inwardly between the meeting edges of the plates when in their open positions as shown in Figs. 2 and 3, thereby allowing the curtain to be raised and lowered and held in position by the usual means employed for curtains which are drawn from the bottom upward.

By making the disk 11 of bendable metal, the central tongues -l6 may be readily bent inwardly or outwardly as may be desired according. to the location of the curtain either at the bottom or top of the window. As previously stated this disk -1l also forms a convenient anchorage for the adjacent end of the coiled spring and in order that the attaching helix of said spring may be held against relative tilting movement of the disk, portions of the latter at opposite sides of the center are depressed to one side of the plane of the main body to form raised quarter circular ribs 20 on one side of the disk and corresponding channels or grooves 21 in the opposite side of the disk, said grooves terminating in apertures -22 through said disk for permitting the adjacent helix of the coiled spring to be readily inserted through the channels 21 as shown more clearly in Figs. 4 and 5. That is, the apertures 22 define the ends of the channels which are formed by pressing the intervening portions of the disk to one side of the plane of the main body thus leaving a bridge -2 between the adjacent ends of the channels, such bridge being in the plane of the main body. It is now clear that the channels engage one side of the helix of the spring passed therethrough, while the bridge engages the opposite side of said helix and prevents relative tilting of this portion of the spring when the latter is under tension.

The catch carrying disk 11- is additionally held upon the adjacent end of the roller 1 by means of a ferrule 25 which is tightly fitted upon the periphery of said roller and has its outer end overhanging and preferably engaged with the flanges 15- and 17, thereby forming a shield to protect the sliding plates in a measure against contact with external objects which might interfere with their free action and at the same time the ferrule gives a certain degree of finish to the end of the roller and aids in positioning the curtain or shade upon said roller. The main features, however, of the invention consist in providing a one-piece catch carrying plate with means of attachment for one end of the coil spring, additional means for holding the spring against tilting movement relatively to the disk, and further means for retaining the catch plates in operative position there on and for holding the cat-ch plates when necessary against inwardmovement toward each other.
