Patented Ang. 10, 1915i vApplication led February 11,1910. Serial No. 543,229. n
To all whom t may concern:
Be it known that I, JAMES WASHBURNE, a citizen of the United States, and resident of Fulton, in the county of Oswego, in the State of New York,`have invented new and useful Improvements in l/Vindow Shade Rollers, of which the following, taken 1n connection with the accompanying drawings, is a full, clear, and exact description.
This invention pertains to shade-rollers of the class in which the roller `proper is formed hollow. for a portion of its length for the reception of a stationary supportingspindle which is surrounded by a spiralspring connected at its respective ends t0 theroller and spindle and serving to automatically wind the shade upon the roller, which latter has fastened to one ofr its ends a plate or disk carrying a-pairvof catchescooperating with a notched spear secured in the adjacent end of the spindle to hold the roller against the unwinding action of the spring.V n
The present invention is particularly related to thetype of shade-rollers in which the spiral-spring has its .inner end attached to the spindle and its outer end connected to the roller.
The object of this invention is to provide a simple rigid and reliable attachment of the spiral-spring to the catch-carrying disk or plate secured to the roller, and at the same time produce a structure which will permitk the parts to be easilyfand quickly assembled.
f To that end the invention consists essentially in the combination of a hollow roller, n
a stationary spindle disposedlin one end of said roller, and provided in its, outer end with a so-called spear engaging a supporting-bracket, and a spiral-spring surrounding the spindle and having its inner end secured to the corresponding end of said spindle, and a flat metal disk rigidly secured on the end of the roller land provided withv a central annular opening through which the aforesaid spear passes, said disk being formed on its inner face with a circular channel which partly surrounds the aperture and is opened at both ends, and the said spring having its outer end portion secured in said channel.
-Furthermore, the invention resides in the novel manner of forming the circular channel on the disk.
In the accompanying drawings Figure'l is partly a yside view and partly a longitudi- ,nal section of a portion of a shade-roller .verse section of the catch-carrying disk detached and a portion of the spring attached thereto; Fig. 4 is an enlarged end view of the roller with ca'p removed; Fig. 5 is an enlarged detail inner face vie'wof said disk. Like characters of reference indicate like parts in the several views of the drawings.
k denotes the roller which is usually composed of wood and is provided with a longitudinal vbore `-2 extending from one end .partway the length thereof, to which roller is attached theY shade 3fdesigned to be lwound thereupon in the well known manner. Y'
-/l denotes the usual cylindrical wooden spindle which is disposed within therbo're -2 and is of such diameterr as to allow it to bevsurrounded by the spiral-spring which is common to all shade-rollers of this character. Y Y The spindle `passes `*freely through thespi'- ral-spring and may have the inner end of the spring secured to its corresponding end in anysuitable and convenient manner.V Howusual metal spear -which isformed with an annular huh-Y- `providedwith two diametrically disposed notches -8-S-, the outer end portion'ofwhich spear is fiattened, as indicated at -9-, and seated in the usual correspondingly shaped elongated opening -10provided in thewell known supporting-bracket l1- designed to be fastened to the window-casing.
By the rigid attachment of the spear to the spindle and the locking engagement of the spear with the bracket, the saidspindle is held against rotation.
i To the end of the roller ladjacent to the spear is Xed a Catch-carrying member l2- which may be of any suitable or well known form and is detachably secured to saidspear 6 f metal at ythe edge of the aperture being A flared toward the endofthe spindle to lform -the disk, abuts .the spindle.
vslipping circumferentially on the roller.
The said disk is formedwith a central circular aperture M14-f througlrwhich aforeextends, vthe portionof A'the a loose journal .for the-roller :upon vthe inner endy portion of the hub -l7, and whereby against the adjacent 4end of -l-l-.denote a pair of catchesxwhich are carried. on Athe outer #face rof :the fdisk l2- andanay be. of any .Wellfknown form.
'In fthe `present .instancethe :said catches arel of the.` formy shownand described .in my Letters Patent referred to. and they :consist Y ofl flat plates adapted .to slide on 'the outer face of lthesdiskand having their adjacent edges-:cut outeto accommodate. thehub "7- on the spear -'6- when the said .plates move toward .thesaidfhubl 1r:'Ihesaid edges of the Y platesVK are` 'formed "with tongues -16-16-; adapted Zito, engage theaforesaid notches -8*S-, one at aitime. @Said catchpla'tes are r supported .1. on" the' diskby providing the latter with flanges -jl`7-eilg7-l-S-18Q formed by Abendingthe marginall'portions of thedi'sk at rigfn'tV angles. '@Lheltwo opposite flanges -17-17- termina-te. Ain inwardly projecting lips -19--19-..to vserveas .guards for thesliding plates.
V'Inafsmuch as this invention 'does-notl per` tain to the catch-plates :Yori their i carryingclisk,`fu1ther description and illustration of said parts are unnecessary.
As hereinafter stated, #the presentinvention resides inthe attachmentof-the outer end ofthe spiralfspring. -5--. y
- lllhen catches f of "the aforesaid form a-re employed, I prefer Yto connect'the spring directly to the disk 412;. To effect this connection, the disk is provided on its inner face with a circular-channel 20 which is open .atboth .ends to permit the end helix of the spring to be threaded therethrough. YThe end vportion of the wire is extended suf- 'iciently to allow it to be clenched onto the adjacent end ofthe channel.
To produce this channel, the sheet metal disk is subjected to the action of a die-press which is Adesigned to slity the disk on two shortr-radial lines of the .same length and which are -disposed equidistantly from the central aperture of `the disk, and coincifdently with ythis slitting-operation, the metal'is thrown out onone 'face of the disk kin -the formof a Isegmental rib, of U yshape crosssectionand extending 4fromone slit to the other .anddisposed concentric -with -the central f aperture.
.'.Iyprefer .to extend. thesaid channel halfway around 4the central aperture so Ias to insure a stronghold ofthe spring -on ithe disk.
In. a shade roller, a fone-piece catchcarrying .plate .having a central circular opening anda semi-eircular channeled rib concentric with-said opening andwholly at the inner side of=the planeofthe plate, the channel `extending'lengthwise ofthe rib and opening at both ends thereof to receivethe end of ya roller-retracting spring.
. 2. -In a. shade roller, anne-piece catch-carrying platehaving its opposite vedges -provided with :outwardly .projecting catchguiding flanges in combination with opposed radially sliding catches guided by said flanges, said plate havingfa circularecentral opening and an inwardly projecting concentric rib provided withy a lengthwise channel extending across Vandto opposite sides of-xthe meeting edges of said zcatches and open at both ends to receivethe-end of a roller-retracting spring.
