The invention Wil-'l novvbe described-'with reference to the accompanying dra-ndngs wherei nA Fig. l'showsa longitudinalse'ction* of a springv rollerf constructed according to'I the invention; Y

Fig. 8 shows the invention applied toa sash iwinfdow.
The roller L is recessed in the usual inann'er vto accommodate central: spindle Z) 6o around which is `coiled a'spring 0 oneen'd fof the springsbeing attacned to the spindle atE (Z Whilst the other-end of the spring 'is atafcl'iedet e to-projectionsiffon afdiscffg secured to a sleeve `or socket Z. The spindle Z) passes through aicentral Vhole inlthe'di'sc gend is prevented from longitudinal Inovenient by' pins p. The projecting end IMO the spindle is inthe' forni of a flat hoolenclfhas pivoted thereto e catch y' whichiis` adapted 70 to engage with one or inore' internal projcctions or stops ls-in the sleevefoi' sockety Z secured to the end oi' the roller a,-Which"is suitably recessed Afor' this fpurpose as shown. The spindle@ may befsuitably recessed as indicated at m so that the catchuinay pivot Y over a 'flat portion'thereofir andlinrorder'to' provide stops for liniiting. the-y pivoting movement of ithe catch.' TheY 'projecting lend of the spindle'may'fbewprovidedwitlr :ahole 80 at m for the reception of a nail or suitabie tool 'for the purpose `of f rotating .the spindle for winding up the' spring 'before the roller isplaced in position-w Thebra'cketor pli-ate nto receive thepro-jectingend-'toflthe'spin- 85 dle isi provided Lvvi'th a'eslot ato; thesl'otbeing of al length corresponding Withth'eldepth of hooked end :71, 'and lso 'arranged that' normallv the catch*- j Will hang. vertically down- Wards.l The pivot Qjofithfei spring 'roller 90 isi adfipted toy engage with i a @slot15 @of inI a bracketlt. Thfecbraclet's 'n and rzare secured inpositiony by- -ni'eansof! pointed tags i", adapted .to be` driveninto the top offafwvindow frarneyandf by a suitable securing 'mem- 95 bier,I such as a nail or 'sore-iv, passirigthrough the. hole ufanddriveny into the side of the In iorder 'to 'hold the brackets-atfthe-required distance fromrthe sides oftliewindovv traine7` the)T are' provided 100 with flanges@4 Y `When placing-the rollfei'a,-inposition the spring 0 is first' tensioned by turni-ngthe spindle Kwhereupon the roller a is vslightly tilted'from the'horizontal positioniso'as to 10 bring; 'the-catch" j finto 'engagenient'fv with the the stop )or 2 projection la (es shown.' linl dotted lines in Fig. 1,) and the spindle o is then slightly released so as to produce the locking action. With the roller held in the no tilted position, the hooked end h is fitted into the slot o, whereupon the roller is raised to a horizontal position and the pivot Q at its other end fitted into the slot w of the bracket t. The screen or blind m is then slightly unwound and the catch f falls by gravity into a vertical position in which it is disengaged from the stop (full line position Fig. l). It the free end of the blind or screen m is attached to a sliding window sash y (Fig. 8) it will thus be seen that as the sash is .raised or lowered the blind is unwound or rolled up in accordance with the movement ot' the sash.
In order to remove the blind c the pivot Q is removed it'rom its bracket and the roller a must be tilted in order to remove the hook 7L from the slot o. 'lhis tilting movement causes the catch j to engage automatically with one or other et the stops 1 and thus prevents the spring trom being unwound.
The invention as above described is more particularly applicable for screens to be applied to windows so to prevent flies and other insects or dust troni entering when the window is open, but it may also be used tor other purposes such as for blinds for drawing over windows.
With the arrangement as above described it is possible to it the end oit the ot the roller with the locking device irstly into its bracket and then to t the other end ot the roller into the second bracket.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l. A spring roller for blinds and screens comprising a roller having a recess at one end, a pin at the other end of said roller, a sleeve secured to the recessed end of said roller and forming an extension ot said roller, a bearing plate iixedly secured inside said sleeve, a spindle revolubly mounted in said bearing plate and in the recessed end ol said roller, a spring coiled around said spindle, one end ot said spring being secured to the spindle whilst the other end thereof is secured to the bearing plate, pins passing through said spindle and being arranged on opposite sides ot said bearing plate so as to prevent axial movement of said spindle, inwardly directed stops secured to said sleeve, a catch pivotally mounted on said spindle, said catch being adapted to pivot in a plane parallel to the longitudinal axis of said spindle. the cooperation between the catch and the stops being such that when the roller is moved Vfrom a horizontal into an inclined position the catch falls by gravity into engagement with one ot the stops and remains in engagement therewith even after the roller has been returned to a horizontal position,
but when the blind is slightly unwound the said catch falls by gravity into a position in which it is disengaged from the stop, a hook shaped extension formed at the tree end of said spindle, and a slotted plate, the slot in said plate being adapted to receive the hook shaped extension, said slot being ot such a size that the hook shaped extension can only be engaged and disengaged from the said slot when the roller is in an inclined position, thus ensuring the catch being brought into engagement with one ot' the said stops.
2. i spring roller tor blinds and screens comprising a roller having a recess at one end, a pin at the other end oi said roller, a sleeve secured to the recessed end of said roller and forming an extension ot' said roller, a bearing plate tixedly secured inside said sleeve, a spindle revolubly mounted in said bearing plate and in the recessed end of said roller, a spring coiled around said spindle, one end et said spring being secured to the spindle whilst the other end' thereof is secured to the bearing plate, pins passing through said spindle and being arranged on opposite sides ot said bearing plate so as to prevent axial movement of said spindle, inwardly directed stops secured to said sleeve,
said spindle having a recessed portion ex-v tending substantially to the longitudinal axis ot said spindle, a catch pivotally mounted in said recessed portion and adapted to be accommodated therein, the recessed portion being ot such a length so as to limit theV pivoting movement of said catch, said catch being adapted to pivot in a plane parallel to the longitudinal axis of said spindle, the cooperation between the catch and the stops being such that when the roller is moved from a horizontal into an inclined position the catch falls by gravity into engagementV with one ot the stops and remains in engagement therewith even after the roller has been returned to a horizontal position, but when the blind is slightly unwound the said catch falls by gravity into a. position in which it is disengaged from the stop, a hook shaped eX- tension formed at the free end of said spindle, and a slotted plate, the slot in said platel being adapted to receive the hook shaped extensionn said slot being of such a size that the hook shaped extension can only be engaged and disengaged from the said slot when the roller is in an inclined position, thus ensuring the catch being brought into engagement with one of the said stops.
In witness whereof l hereunto subscribe my name this 20th day of May, 1925.
