Serial 380,014. Y

My present invention relates to roller screen mountings of such a type as 1s used to supply windows with fly screens as permanent fixtures, the screen being drawn down when o in use in the manner of a Window shade and at other times rolled np upon a spring roller and the invention has for its object to proviclea simple, cheap and serviceable mounting of this kind having certain advantages in construction and mode of operation. The improvements are directed 1n part toward providing a certain elasticity in the assembly of the parts whereby the fixture need not be cut with extreme exactness in order to fit the window casing and further toward providing simple and accessible means for varrying. the tension of the roller spring.

To these. and other ends the invention resides in certain improvements and combina tions of parts, all as Wlll be hereinafter more fully described, the novel features being pointed out, in the claims at the end of the specification. g V

180,122,"filed Apri1' 1, 1927,11; whijclijis shown to Ja -large extent a 'window screen fitting of'the general nature here involved, but claiming princip'allythe means for extending the screen from the' roller support over th -window 'openingiandsecuring.it in I place While,as"above stated, this ease-amass intimately concerned with the'l' cfonstrncti'on and mode ofopeiation of thefscreen roller itself. Asin my former base referredto, I have also shownfinthis case, butin a general way,'(F ig."1) a' window casing Ahaving a sill B. A screen roll casing indicated gen: erally at C issupported at the top of the win: dow frame in bracketsD andE. The sc'r'een itself is indicated at F and-terminatesin a bottom' rail G. d In thegeneral showing of Fig. 1 the screen ;is shown'extended in opera} 'tive position tofcover. the win'dow opening-Ref flange on an end plate 4: provided with a.

downwardly, extending attaching portion!) also provided with screw holes 6 and of which the aforesaid attaching portion 2 constitutes an inturned flange, t-he'idea. obviously being to form a corner bracket fitting the corner of the window casing. The general shape of the bracket is semi-circular or serni-cylindrical and the edges of theend plate 4111 continuation forwardly of theback plate 1 are alsoturned inwardly to constitute a spacing flange :7 Astrap 8 encircles-this flange: on the outside and a similar strap or band 9 on the inside, whichtwo straps are. held in place by bent over. ears. 10 that are extended through openings in, the spacing flange. and the otherstrap as shown'i'n Fig. .14, said ears being preferably formed'integrally with one, the inner, strap. g ,f

The two straps 8 and 9 thus spacedfrom av socket .of substantial. depth for a, similarly shaped sheet metalcasing element previously indicated at C,..the ends .of which telescop ically fitthese sockets as best-shown inFig. 2. The'ideain general is that-.if'a number of screen mountings are. cut to the same length to fit windows of generally the samesize and yet the window frames vary a little in their individual widths, then, in that case, thesli'dability of the casing C in the endbrackets willmake upfor the difference; The exterior appearance will be the same. on allhof the windows, ,and'theiengagement of thefcasing wit-lithe brackets will be secure eventhough theicasing does not in each instansefeigtend the'full depth thereof.

' Secured to he end plate of eachbracket is an inwardly projecting tubular hub 11, the ends of which maybe fastened thereto by bent over-ears 12 formed thereon and'extendin'g through the plates. These hubs are ofsubsta'ntial length, that is, they should preferably belonger. than the widthof the, socket forming strap 8 and'f9. The tubular core 13of the screen roller is mountedon these hubs into which thelatter projectsandhere againthe element offe'zztensibility'is introduced so that if'the said-core is .cut relatively short ascorm pared with the separation ofthe brackets D andEfdue to a slightly greateriwidth of the window casing' itwill adjust itself teles'copically on the hub supports 11 and still be adequatelysupported. V i h The screen roller itself embodying this central core piece 13'c0mprises alsoan outer. winding shell 14 surrounding the. core and supported'in spaced relationship thereto to form a chamber 15, in which latter'is housed the spiral te'usioning spring lfithat surrounds the core, as shown, and winds the'roll. The shell 14 is so supported on the core by means of a pair of collars 17 and 18, which turn freely on the core but which are on the other hand, locked to the sleeve or roller shell 14. The mode of'locking them is preferably as follows; f. I The collars 17and 18 are preferably composedof annular castings having a plurality' of indentations 19 in their peripheries at separated points.v -With a suitable die, I punchportions of the shell into these indentations was shown at 20 in Fig. 5, so that the shell is thereby locked to the collars against both relative, rotative and endwise vmovei'nents, which arrangement, in view of dering, while at the same timesecuringbe-.

tween them, the inside edge of 'the screen F,

' as also clearly shown in Fig. 3, and also in Figs. 7 and 8." further shown in these same. figuresfthe screenpasses from'this point of attachment on the roller shell out through an opening 23 at the rearand botco ner casing C and adjacent to back plate 1, asshown in Figs. 7 and 8.

This opening 23 is'provided'forinthe' mode of attaching casingG to the bracket supports 1) and 'EthrQugh the provision of the sockets in the 'latter, afo'resaid, in. the followingmannerih I i The casing O embodies a backing or base plate 2% to which it is attachedat the 'top (Figs. 7 and 8) by interlocking flanges indicated generally at 25. "At the'bottom, it is doubled back or flanged at 26" so that this edge interlockswith the outer strap 8 of each bracketas the casing is slid lengthwise into engagement with the latter. At the same time, the base plate 24 engages in the rear of the portions 1 of the bracket, its'lower edge being engaged under a finger 26a on1the attaching portion 2 thereof. It is for this reason that theattaching portion 2 is offset from the bracket. portion 1 and when the parts 7 are assembled, as just .described, a substan 'tially flat'or continuous surface is presented atxthe rear to go against the window casing.

are free onthe,core', or, rather, the core is free to turn relatively :to these. COlljarsand to the shell. One end of the spring 16 is en: gaged with the core, 13, as indicate d'at-r27 in Figs. 2 andv 6,:bybeingsecured to the eye of a cotter pin 28 extending through the latter The other end 29 is anchored in the opposite collar 18, as shown in Figs. 2 and 8.

The core does not turn but remains fixed durlng operation of drawlng the screen down from the roller shell 14 which latter then rotates freely on the core. The screen is red turned by the spring 16 rotating the shell 14 the beforementioned movements by reason of channels on one end thereof'that interlock with ribs 31 on a sleeve 32 that itself turns on hub 11. However, sleeve 32 is fixed to a worm gear 33 supported in bearing bracket 34 attached to the inner side of end wall 4 of bracket E. Meshing with this worm gear'is a worm 35 (Figs. 4 and 11) also hav ing bearings in bracket 34 and having a shaft or stem 36 extending downwardly through and to the exterior of the said bracket and the general casing or housing of the mechanism. This stem is shown channelled at 37 .in the manner of a screw head so that it may It will be be rotated with a suitable. tool. understood from this without further explanation that turning the worm slowly rotates the worm gear which, through its sleeve 32, rotates the core and hence changes the tension of the spring to store greater or less power therein as desired according to the direction of the turning movement.

A device constructed in accordance with my invention as herein described and shown has few parts which are easily assembled and can be readily applied to its position on the window frame once the casing C, shell 14 and core 13 are cut to approximately the proper length. It is further pointed out that the interlocking for rotation of the worm gear sleeve with the core does notinterfere with the longitudinal sliding ad ustment of. the

' core thereon and hence, indirectly, on the hub 11.
