SHADE-ROLLER.

Specification of Letters Patent.

Patented May-8, 1917.

Application filed October 21, 1916. Serial No. 126,818.

To all fio/wm t may concern Beit known that we, EMIL KnAnMi-iii and sliade-rollers, the object being to provide a shade-roller that can be fitted to windowframes of different widths. ln other words, our improved shade-roller includes a spindle which is adjustable longitudinally of the casing therefor, said 'casing beingin prac-` tice a shade-roller.' To arrange ourshades roller for window-frames of various sizes,

wardly, hence in order to attach the `shade` roller to'window frames'of-'diifere'nt widths, it is but -necessary to adjust the longitudinally movable spindle. ln yanother em`-' bodiinent'of our invention, the spindle may be `arranged to v-be forced` inwardly by the spring.7

We 'will now 'proceed to describe 'our 'inventi'onin detail, theessenti'al features' of* which will be summarized in the'appended claims, referencel beingv had to the acycoinp anying .draw-ing, forming part hereof,

wherein:

li`ig.`7 is a fragmentary sectional detail` view, the'section being taken'on aline 7?-7 in Fig. 1. y

As herein embodied, our improved shades! roller consists offa shade-carrying"casing7l extends longitudinallyl thereof for the" greater'part of its length, said clfaniber having in communication:v therewith" a some what smaller bore or chamber-`9 to receive'A thev inner end of a spindle 10. The spindle'tt'-` 10 is herein illustrated as tubular, but may be solid if desirable. The spindle 10, whether tubular or solid, is` provided=with longitudinal groovesll to be engaged bythe pawls or dogs 12'whichfare' carried at@ plate 13 which is'loosely tted to and sur` rounds the spindle 10.

To one end of the casing '7, w'e secure' a cap 14 which is carried' by a turned d'own'or reduced portion 15' ofthecasing7, pfrovidedl'T/ with' slots' 1S'to receive the ribs19'on; said cap, (see'Fig' 5). The'rib`s-19fare formed' by striking down al portionof'the wal-lof the'cap y14 and serve astkeys lto engagefthe recesses QO'in the `p'awl-plate13, -whereby`-80 said plate is held againstl rotation;

As can'b'e'seen in Figql, the pla-teV 13 iis located in' the chamber 21, -foimed'byT the cap 14 and partlyins'ert'ed end 'of the casing" 7. To keep the plated?) in position we 'proiA 85 videl the side-wall ofthe cap 14 with stops 22 laterally expanded-'from the oute'rends of the ribs'19 (see'Fig. 3)'. f The plate 13'as shown b vdotted'linesin'Fig. 3 lis'lo'c'a'tedA between'the stopsfQQand supplemental stops *'90 S22aonf the capv (see dotted lineFig. 3), whereby longitudinal displacementf of "Y the plate 13 is prevented- The'plate'landfcap 14 arepro'vid'ed 'with flanges 24 land 25, rer* spectively, around f the" openings" therein', 95=V through which the spindle' f 10 passe'sy'to"vl serve asfbearings for th'ef'spindl'eflO;

To effect an outwaidmovement ofthe spindle 10,when the'rollerlisremoved from the brackets QG and 27,: we providea fspringilOO 28, the spring normallyextendingthe` spin? dle outwardly, the ini'ier'iend'ofthe spring being secured 'to thespindle'l() 'atQTthe outer 'end being' secured to th'eiplatfe 13.* To

securethe outer end'of'said spring to"said"105'-" plate, we provide `eyesZSa' (seeFigs.` Q'and I* 4) formedI f 'by'` striking out some ofthe material of said plate. The free end"of"thel spring is'passedfthiough the'fey'es 28a, and

clenched.

@ne end of the casing 7 carries a threaded adjustable trunnion 29, having a rounded portion 30 to engage the opening 31 in the bracket 27. The adjustable trunnion 29 permits the shade-roller to be centered relative to the Window-frame. The spring 28 may be arranged to normally extend the spindle 10, or tonormally retract same. To adapt the spindle 10 for engagement With the bracket 26, to prevent the premature Withdrawal thereof, We may split the end thereof as at 47 a and expand or spread the split end to form yieldable projections 48a, which can be forced through the opening 32 in the bracket 26. The expanded end of the spindle 10 will prevent the premature witlr draival thereof when the spring 28 is arranged to normally retract the spindle 10. To prevent the rotation of the spindle 10 when the casing is rotated, We provide the bracket 26 With projections 49a extending into the opening 32 to engage the grooves 11 in the spindle 10 (see Fig. 7

When the casing 7 is rotated, the spring 28 Will be Wound up, and retained in a Wound up or partly Wound up condition by the pavvls or dogs 12 in the usual manner. To prevent the spindle 10 from being forced too far outwardly, when the roller is removed from its brackets, We provide a stop pin 33 (Fig. 1) which Will strike the flange 24 on the plate 13 and limit the outward movement of the spindle 10.

In the form of our invention shown in Fig. 6, the casing 34 is provided With a chamber 35 containing a spring 36 surrounding a spindle 37. The spring 36 may be secured at one end thereof to the casing 34 at 38, the opposite end of the spring being secured to the spindle 37 at 39. The spring 36 may be arranged to normally extend or to normally retract the spindle 37. The spindle 37 is provided with grooves 4() extending longitudinally thereof to be engaged by paWls mounted on a plate located in the cap 41. The cap plate and pavvls employed in this latter embodiment of our invention vvill be the same as illustrated in Fig. 1; hence, a detailed showing thereof has been omitted. In this latter embodiment of our invention We provide the outer end of the spindle 37 With notches 42 to engage the side-Walls 43 of a javv in a bracket 44, to prevent the rotation of said spindle.

The opposite end of the casing 34 carries a cylindrical trunnion 45 similar to the trunnion 30 in theform illustrated in Fig. 1, rotatably engaging a bracket 46. 'Io adjust the roller to a Window-frame of greater Width than the roller is arranged for, the spindle 37 Will be moved longitudinally of the easing and the notches 42 caused to engage the bracket 44.

What We claim as our invention is:

1. In a shade roller, a longitudinally movable spindle, in combination with a casing containing the same but permitting such movement of the spindle through the end of the casing, means carried by the protruding end of said spindle to engage a fixed bracket, a spring surrounding said spindle and attached thereto at one end, the other end being relatively fixed within said casing, the said spring acting to cause the longitudinal movement of the spindle and also serving to rewind the roller, and the bracket-engaging means carried by the spindle maintaining the latter in its longitudinally adjusted position against the tension of the spring after said spindle has been longitudinally adjusted.

2. A shade-roller consisting of a casing adapted to be rotatably supported at one end thereof by a bracket, a spindle carried by said casing and the outer end of which is adapted to be engaged by a bracket ar ranged to prevent the rotation thereof, a spring Within the casing secured to said spindle at one end thereof, a plate located at one end of said casing surrounding said spindle but free to rotate thereupon, means connecting said plate and said casing, means to connect the outer end of the spring to said plate, pavvls carried by said plate to engage said spindle, said spring acting to move said spindle longitudinally of the casing and means to prevent said plate from moving longitudinally of said spindle under the action of said spring.

3. In a shade-roller, a casing, a spindle carried thereby provided With grooves lon- ,gitudinally thereof, a cap carried by said casing at one end thereof, the end Wall of said cap being spaced from the adjacent end of said casing to provide a chamber, a plate located in said chamber provided With an opening for the free passage of said spindle, pawls carried by said plate to engage the grooves in said spindle, means carried by the cap to engage said plate, and a spring connected at one end thereof to said plate, the other end of said spring being connected to said spindle.

4. In a shade-roller, a casing, a cap at one end thereof, the end of said cap being spaced from the adjacent end of said spindle to form a chamber, longitudinal ribs carried by said cap, a plate Within said chamber provided With recesses to engage said ribs, said plate being provided with a central opening, a spindle passing loosely through the opening in said plate and through said cap, the spindle having grooves longitudinally thereof, pawls carried by said plate engaging the grooves in said spindle, and a spring secured at one end thereof to said spindle.
