Specification of Letters Patent. Patantned July l't', JILFlW,

Application filed January 29, 1915. Serial No. 5,092.

To all whom it may concern:

Be it known that I, ALns'sANDRo Fonnnn, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new Wlndow-Screen, a full, clear,

and Improved of which the following is and exact description.

This invention relates to improvements in wlndow screens, and has for an ob ect to means to install same wherever desired as" for example; between the window frame, as shown in Fig. 3 or outside of the frame Referring to the .drawings Fig. 1 is a sectional View of the adjustment showing its respective springs, pole 'and roller. Fig. 2 is an elevation view of the screen partially rolled on the roller. Fig. 3 is a side sectional elevation of a window frame showing roller and screen. Fig. 4 is a front elevation of part of the guide one of which is mounted on each side of the window frame. Fig. 5 is a detailed view of the guide and its adjustment slots. Fig. 6 is a side elevation of the duplex spring attached to the screen. Fig. 7 is a front view of Fig. 6. Fig. 8 is a cross sectional view of Fig. 4. Fig. 9 is'a cross sectional view of Fig. 5.

Referring to the accompanying drawings by numerals.

Screen 1 is tightly attached to roller 2; pole 3 is set on supporters 4 in order that when screen 1 is being pulled it will'cause roller 2 to rotate; while roller2 is rotating springs 5 and 6 willwind around pole 3 which is held by supporters 4. The metallic cords 7, attached to the side edges of the screen 1, are adapted to traverse the grooved pulleys 8 and the slotted guide tubes 9 when a metal border plate 12, attached to the lower end of the screen and carryingthe duplex springs 10, is grasped and pulled downwardly in unrolling the screen. en the duplex'springs 10 have reached the rods cable mechanical arran 'e cation, they will be engaged. thus holding screen 1, preventing same from being rolled back, by springs 5 and 6.

; When it is desired to roll the screen up,

'it is only necessary to apply a slight upward pressure or jerk to the plate 12, thereby disengaging the duplex springs '10 from the keeper-rods 14, whereupon the springs 5 and 6 .act on the roller 2 causing the screen to v be wound thereon.

The slots 15 are for the purpose of adjusting'the guides 9, so that they keep always perpendicular and parallel the guides 9.

' From the foregoing description it will be apparent that the invention provides an exceedingly inexpensive, simple and practiment; that it may be installed on any of t and that it will be eflective and reliable in operation.

While the preferred embodiment of the invention has been shown and described in detail it will be understood that I do not wish to be limited to the construction set forth since various changes in the fornn, proportion and arrangement of parts andQin the details of construction may be resorted to without departing from the principle and scope of the invention.

Having thus described the invention, 1 claim:

1. A window screen mechanism having a spring roller and a screen attached thereto, guideways for retaining the side edges of 14 which are stationary on the window frame and may be placed at any desired lo-v e present windows,

the screen when extended, stationary keeper 3. A Window screen mechanism having a keeper rods to frictionally engage the same spring roller and a screen attached thereto, and hold the screen extended. guideways for retaining the side edges of the screen when extended, stationary keeper ALESSANDRO FORNER" 5 rods arranged in pairs in parallel relation, lVitnesses: and curved spring holding means carried EMILIO VASGORN,

by the screen forinterposition between said J OSEPHVIGLIANO.
