I II A arroe/vez Patented May 6, 1952 3 UNITED STATES PATENT. OFFICE 2,595,364 SCREEN RLLEB. v n I Hughbert M. Lockhart, Highland Park, Application July 21, 1947,' Serial No. 'z zs a My invention relates to 'a new and useful improvement in a roller screen for windows and adapted for mounting in connection with a slidable window in such a manner that when the window is open, the screen will automatically be unrolled and cover or screen the open space.

It is an object of the present invention to provide a roller screen ofthis class which will be simple in structure, economical of manufacture, durable, compact, light, easily and quickly installed and highly eflicient in use.

"Another object of the invention is the provision of a roller screen of this class so constructed and arranged that when the window is closed, the screening member; is entirely enclosed within a housing.

Anotherobjectof the invention is the provision ina roller screen of this class of a construction whereby the device may be easily and quickly mounted in position on a window and when mounted is prevented from undue disconnection from the attaching parts.

Another object of the invention is the provision in a roller screen of this class of a structure so arranged thatthe screening member will extend substantially from side to side of the window and be pressedat its edges against a stop sojthat a complete sealing of the window at the edges is thus provided.

' Another object of the invention is the provision in a roller screen of this class of a supporting bracket for supporting the roller on which the screen is mounted so arranged and! constructed that thescreen itself at its opposite edges may'project beyond the inner ends or facesof the supporting brackets.

Another object of the invention is the provision in a roller screen of this class of a structure so arranged that the screen may be prevented from unwinding after being removed from its mounting;

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made in the detail of structure illustrated without departing from the invention itself and it is intended that such shall be embraced within the scope of the claims which form a part hereof.

The invention is adapted for use with a slidable window. In the drawings, I have shown a window sash Ilvertically s lidable in the window frame l8 and provided with the lower rails 19. The window frame is also provided with a sill Zll against which the lower face of the rail l8 engages when the; window is fully closed.

In the invention, I provide a housing embodying the top wall 2|, the outer wall 21, the bottom wall 22, and the downwardly projected flange 23 extending downwardly from the top wall 2|. This downwardly projected flange 23 is provided at spaced apart points with the inwardly extending notches 24 adapted for the reception of mstening means 25, such as, nails or the like which are driven into the rail l9 of the window sash so that the housing will move in unison with the window sash.

At opposite ends of the housing, I provide supporting brackets which are U-shaped in formation and the legs 26 of which are secured by welding or inj any other suitable manner to the inner faces of-the top wall 2| and the bottom wall 22. The bight 28 of this U-shaped structure is inwardly off-set at its center to provide the U- shaped formation 29. In one of these U-shaped formations 29 is formed a slot 3|), the purpose of which will appear hereinafter. In the other U- shaped formation is formed an opening 3| which is central thereof.

I provide a tubular roller 32 which is preferably formed from metal and into which is pressed as a press fit a disc 33 having a. trunnion projecting outwardly from its outer face and adapted to project through the opening 3 I. This tubular roller 32 is cut away at one side, as at 35, so that the insertion of the trunnion 34 through the opening 3| may be effected and theroller positioned as shown in Fig. 4. It will be noted that the disc 33 is set inwardly from the end of the roller 32 and that the roller 32 terminates with its end substantially in engagement with the inner face of the bight 28 of the supporting bracket.

Pressed inwardly of the roller 32 at the opposite end by a press fit or suitably secured thereto by welding or any other desired manner, is a cupshaped support 36 projecting centrally through which is a rod 31 embraced by a coil spring 38. One end of this coil spring 38 is angularly turned and directed: through the lug 39' formed on the face of the cup-shaped member 36. The inner end of the rod 31 is split to provide the space 40 for reception of the angularly turned end 4| of the spring 38. is flattened at both sides to provide a fiat faced structure and this fiat face structure is adapted to engage in the slot 30 formed. in the inwardly pressed U-shaped formation 29 so as to prevent rotation of the rod 31 relatively to the: bracket;

' Formed through this flat portion inwardly of the bracketis. an opening. 43, the purposeof which will beexplained later, and which is in alignment with an opening 44 formed through the tube 32. Gluedor otherwise suitably secured to the-periphery of the tube 32 is one end of a screen46, the opposite end of which is reenforced by the reenforcing plates 41 and 48 which carry the angularly turned portions 48a and 41a, the screenbeing clamped at its edges along the free end betweenthese plates. A portion of. the plate 41 is turned outwardly to provide a gripping portion 49. and. this: outwardly turned portion extends angularly to the plane of the main body of the plate-41- and is. slightly curvedat the point where it is turned outwardly, this outwardly portion, in addition to serving as ahand. grip, is provided withnotches ll=which are adapted to engage under aneyeletofa screw 5| which is screwed into the sillandprojects vertically upwardly therefrom.

Inuse, the spring is mounted in the lower end in the manner indicated with all of its associated parts-which have been described By rotating therod. 31 in one direction, the spring 38 may then be wound and when wound in this condition a pin 45 may be projected through the opening 44 and..into the opening 43 so as to. lock the rod 31 againstreverse rotation, this pin being extended through, if necessary, a layer of the screening which is wound upon the roller. The screen, of o'oufrlse will be in unwound position when. the spring is placed under tension. The roller may then be mounted in the housing in the manner indicated andthe pin 45 removed which will permit the roller..32 torotate so as to wind the screen onto the roller 32 fromthe roller 32 will again, of course, place the spring 38under tension and the initial tensioning of thespring 38 is such that when the screen is finally, wound upon the roller 32, there will be a certain amount of tension in the spring 38.; Whentheroller 32 rotates freely to wind the screen 46 thereon, the outwardly projecting portions 45 will engage against the edge of the down-- wardly projecting portion 23 and prevent the edgeireenforcement plate on the end of the screen from-entering the housing but the remaining, portion of the screen will be entirely enclosedwithin the'housing and also aportion of the reenforcing' plates 4! and 48 -so thatwhen. the screen is wound upon theroller 32-, it will be sum-- ciently enclosedwithinthe housing as to protect itfrom the-elements, such' as, snow, sleet, rain, etc:. Thehousing is then mounted in position, as shown iirFig. I. It:will benoted: that the ends of tnewhousingmrescut away, as;at;58, this cutaway:

Any unwinding of the screen 4 The outer end of the rod. 31

portion providing the necessary space for the stop 54, the housing lighting in the space 52 between the

outer stops

53 and 54. The housing is then moved downwardly so that the notches 24 will engage over the nails which project outwardly from the outer face of the sash rail l9, thus mounting the housing detachably on the rail IS. The window is then raised slightly and the screen 46 pulled downwardly. The lower edge of the screen then is tilted so' that the curved or angularly extended portion 49 will extend parallel to the upper face of the sill 20 whereupon the. lower edge of the screen may be moved inwardly'of the sill 20 to engage the eyehooks 5| in thenotche's or slots 50. The tilting or twisting action. is then released and the parts move into the position shown in Fig. 9, thus securely fastening. the lower edge of the screen to the sill 20. When the window is closed, th screen will wind into the housing and when it is open,,it will move into open position. This screen lies between the

stops

53 and 54 and is pressed at its edges against the outer face of the stop 54 by means of the rubberv roller 56 which is mounted on the shaft. 51 journaled in the bead 55 formedon the. edge of. the bottom- 22. It will be noted that the housing 2lextends substantially from sideto side of the window and, thus,. the. screen. also extendssubstantially from side toside of theopening in'the window frame and being pressed at its edges againstthefaceof the stop 54 there is no crack or crevasse; through which flies or the, like. may. be permitted to pass. Another. feature of the screen is that any outward thrust delivered to the. screen will'be taken up by a further unwinding of the roller inasmuch as the screen may. move from the. outer. face of the stop 54 to theinner. face of the. stop 53. By having theconne'ction at. the window sill in themanner described, outward thrust delivered to the screen will not. disengage the connection at the window sill as itis necessary that the lower edge of the screen be rocked in order to release the. eyelet screws. 5|. from the notches 50 in which they engage. I

Experience has shown that a screen constructedin this-mannerv isv one which is most efficient in use and may beleftattached to the windoweven during the winter so that it will serve as a screen against dust when-the window is open and in the wintertime for ventilation. In order to remove the construction from-the window, it will be necessary to grasp-the-lower edge of the screen androck it until the eyelet screws 5| may be disengaged from their notches whereupon the screen may roll into the housing; The. housing may then be lifted upwardly to dis engage the screws or bolts 25 from the notches-24.; When the screen is attached to the window sill the tensionof the screen, of course, keep the housing pressed downwardly so that upward; movement of the housing relatively to the fastening means 25 is prevented,
