This invention relates to screens, and more particularly to door and window screens of the roll type.
The primary ob of the invention is the character which will iect or door opening with which the screen will be fully invention is to provide a screen of this character including guide strips arranged at window opening,
opposite sides of the door or and so constructed that the of the screen and the lift rail forming a part thereof, will be held ment at all times thereby insuring the true winding of the wire me its roller.

Referring to the drawings in detail, the reference character 5 designates the metallic window frame, within which the window screen, formingthe subject matterof the invention is positioned. I
In the present showing, the housing in which the window screen is rolled, is mounted at the upper end of the window frame, however it is erence character 6, is of a length to extend between the side rails of a window or door frame, as clearly shown by Fi ure 1 of the drawings, the housing being rectangular in formation. The ends of the housing are closed by means of the end plates 7, that are so constructed that they fit within the open ends of the housing, where they are bolted or otherwise secured in position.
The housing is formed with a longitudinal slot in the underside thereof through which the wire mesh material of which the screen is formed, and to be hereinafter more fully described, passes into the housing. 7
These ends plates 7 are formed with depending flanges 8 that afford means whereby the housing may be secured inposition between the side railsof the w ndow or door frame with which the device is used. i
The roller on which the wire. mesh material of the screen is wound, is indicated by the reference character 9, and is mounted in suitable bearings mounted in the plates 7.
Secured to the side members of the window frame, are guide rails 26 which are formed by pressing a length of sheet metal material in such a way as to provide spaced walls 27 that have longitudinal recessed portions 28 defining parallel ribs 29, the outer edges of the spaced walls being turned inwardly as at 30, providing a smooth surface for contact with the wire mesh material of the screen.
In the construction of these guide rails, longitudinal flanges 31 are provided, which flanges are provided with openings to receive securing screws to permit the guide rails to be secured in position within a window frame.
together without the use The upper ends of these guide rails are open, the lower endstherepf being closed by means of the keepers 32 that are formed with end pieces 33 which contact with the lower ends of the guide rails closing the lower ends of the guide rails.
This construction permits of the ready removal of the keepers, should it be desired to cut the side rails in fitting the side rails within a Window frame. The free end of the wire mesh material 17, is secured to the lift rail 34 by means ofthe spline 35 that fits within the clamp 36,, which embodies a length of sheet metal material bent upon itself providing side members 37, which are held under the inturned ends 38 of the lift rail.
The construction of the lift rail is such that grooves 39 are formed in the outer surfaces thereof, providing ribs 40 that provide guides for the spring fingers 41 of the guidepieces or shoes 42, which are curved to fit within the ends of the lift rail, the curved walls of the lift rails and curvatures of the fingersinsuring a close fit between'the fingers and lift rail.
Should it be desirable to reverse the lift rail, to provide a clearance for sash hardware or other obstructions, this may be readily accomplished by removing the guide pieces 42 from the ends of the lift rail 34. Tnewire clamps 36 and spline 35,
- and wire 1'7, are now readily removed.
After the lift rail has been reversed, the wire cloth is positioned in the lift rail and the shoes or guide pieces are positioned in the ends of the lift rail.
These guide pieces 42 are formed with elongated heads 43 which when positioned within the guide rails, contact with the parallel ribs 29 to insure against lateral movement of the lift rail. c
As clearly shown by Figure 8 of the drawings, the lift rail comprises two lengths of sheet metal material bent to provide longitudinal groove 44 for the reception of the contact felt 45, one wall of the groove being formed with spurs 46 that are embedded in the felt to hold the felt in position Within the groove of the lift rail. A flange 44' extends inwardly from the lift rail and is formed with an inturned flange 45 closely engaging the flange 46', of one of the lengths of sheet metal of the lift rail. 7
Thus it will be seen that due to this construction, the side members of the lift rail are held of rivets, bolts or similar securing means.
The lift rail 34 being hollow, provides a housing for the sliding bolts 47 that extend through openings in the guide pieces 42, where they project beyond the outer edges of the guide pieces and pass into the guide rails 26 for engagement with the keepers 32.
When the bolts 4'? are in engagement with the keepers 32, the coiled spring 22 is held under having open tension, to rewind the wire mesh material on the screen roller, when the sliding bolts are released or disengaged from the keepers.
The inner ends of the sliding bolts 4'7 are reduced to receive the springs 48 which have their inner ends positioned against the stop 49 that is secured within the lift rail, at a point intermediate the ends thereof. Secured to the sliding bolts 47 are finger pieces 50 that pass through openings in the lift rail, and extend to positions where they may be readily grasped by the operator to compress the springs 48 and retract the sliding bolts 47.
A'modified form of guide to be used in conjunction with a plaster lamb socket is shown by Figure 14 of the drawings. The socket portion comprises a length of sheet metal material bent upon itself to provide spaced double walls defining a groove or guideway 51, to receive the extension 52 formed on the guide member 53. This form of guide rail'and plaster jamb socket is especially adapted for application-to plaster side jambs, and provides a yieldable connection between the extensions 52 and guideway 51. In this form of 54 are provided, which flanges present fiat surfaces to be embedded in the plaster of which the jamb is formed.
From the foregoing itwill be seen that we have provided a metallic window screen which may be readily assembled or disassembled, the various elements of the screen being secured together by frictional contact, thereby eliminating the use of bolts, rivets, solder or other similar securing means commonly used in metallic screen cona struction.
