WINDOW-SCREEN.

Specification of Letters Patent.

Patented Jan.. 1, 1918.

` Application led September 25, 1916. Serial No. 122,106.

dows of various heights, and a screen section which is movable in a vertical direction within the same and adapted to be wound at its upper end upon a spring roller after the manner of a curtain shade.

Another object of the invention is to pro vide a screen having the above named characteristics and means embodied in the frame whereby the screen section may be retained against movement in any vertically adjusted position.

In addition to the foregoing, my invention comprehends improvements in the details of construction, and arrangement of the correlated parts without departing from the'.

spirit of the invention or the scope of the appended claim.

nthe accompanying drawings in which similar` and corresponding parts are designated by thelsam'e characters of reference throughout the several views in which they appear; j

Figure l, is a view in front elevation of a window s creenconstructed after the manner of my invention, and

Figs. 2, 3 and 4, are detail sections taken on the planes indicated by numerals corresponding t9 said figures in Fig. 1.

l/Vith reference to the drawings, 1 indi- Cates generally the vertical frame members of my improved window screen, `and 2 and 3 respectively the lower and upper end frame members connecting the ends of the vertical members. The upper member 3 is formed with a horizontal transversely extended roller casing 4 formed of sheet metal or the like, having an opening 5 in its under side extending longitudinally thereof.

Each of the frame members, l as well as the

frame members

2 and 3 are formed of parallel spaced

sections

6 and 7, illustrated to advantage in Figs. 3 and 4, with their outer longitudinal edges liingedlyv connected by the interengageinent of lugs 8 and 9 provided on the

sections

6 and 7 respectively. The frame members l, 2, and 3 thus formed are provided at suitable intervals with transversely alined openings, ,the openings in the member 7 being internally threaded to receive the correspondingly threaded end of a thumb screw, the shank of which is indicated at 10, and the head 'at 11, said head bearing against the' outer surface of the member 6. Each of the

frame members

1, 2, and 3, is further provided with a series of transversely alined openings indicated at 12 for a purpose which will be presently obvious.

The ends walls 13 of the roller casing 4 provide support for the trunnion of a roller 1l conforming to the ordinary curtain shade roller having a spring therein, the trunnion being mounted within the end wall of the easing to insure operation of the roller after the manner of a shade roller. The screen section indlcated at 15 may be formed of flexible wire fabric, and in the present instance is provided upon each longitudinal edge with a selvage indicated at 16, and formed by bending upon itself a strip of flexible material, which may be fabricor the like and secured to the-wire fabric by stitching or otherwise. The lower end of the wire fabric may be also reinforced in a similar manner by a binding strip 17 The screen section is rolled upon the roller 14, and the selvage edges thereof disposed within the space between the sections G and 7 of the vertical frame members 1 of the-screen frame. A handle is provided for the screen section in the form of a loop 18 of wire or the like secured to the binding strip 17 by means of a strip of metal 19 bent upon itself bers 1 and into oneof a series of openings 21 provided for that purposeJ in either binding strip 1l or the section 16 of the screen section. The. screen may be *further held against displacement by turning the heads 11 of the set screws which cxtend;tl irough the vertical members of the same for binding together the sections composing the same against the selvage edge of the screen section.

The frame of this window screen may be Varied in length by removing for instance, the lower strip 2 from connection with the end of the frame members l, severing said frame members 1 to a degree permitting the same to fit within the vertical height 'of a window and -reapplying the member 2 to the severed ends` Said frame members may be secured together by means of the fastenings 20, which are passed through openings of the series indicated at 12. To facilitate adjustment of the frame to any size of window, it is preferable that the frame members be constructed of wood.

While l have illustrated and described my invention with some degree of particularity,

'l nevertheless realize that in practice various alterations therein may be made, and l therefore reserve the right and privilege of changing the form of the details of conimmer In a window screen, a frame including f vertical side members and a lower horizontal connecting member, each member comprising a pair of strips, apertured ears on the strips, pins entering the ears to connect the strips for relative movement, one strip of each pair having a plurality of threaded openings, and the other strip having registering smooth openings, to receive screws therein which also enter the threaded openings, wherebyv to clamp the strips together. In testimony whereof I afiX my signature in presence of two witnesses.
