tical installation standpoint,rit' is desirable that the latch memberto retain a rolling wlndow screeny in its withdrawn position be located againstr the sill of the window and lyetcarried bythe track proper, and in Lorder sorto do, lprovijde a latch element, which is of substantiallythe construction shown in Letters Patent, No.1,715,858, issued J une 4, 1929, to the RolscreenCompany, as assignee, Which device is capable of adjustment of the finest degreek or adjustmenty of a great variance, such adjustment being accom- 'plish'e'd bya pluralityof openings formed in the latch member and the member` upon which Vthe latch is slidably mounted.

With these and other objects in view, my invention consists in the construction, Iarrangement and combination of the Various parts of my roll screen latch, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims. and illustrated in the accompany- Figure 1y is a plan view "of a. portionl of a window frame together with a lower portion of arolling window screen with m-yimproved latch installed thereon.

The latch element thatI ,provide'is adapted to coact with the ledge 18 for normally holding the screen in its withdrawn position. The side edges of the screen 14 are adapted to travel in guide tracks 20, which are mo'nnte` at 'attaching tlangeV 24 is adapted to restA kagainst the side jambsl() and to be `sec'iired' thereto by screws or they like 27. The screws project-through elongated slots 29 whereby adjnstment-'of thetracks toward or from each other may bev accomplished.

order to provide for proper -adjnstment ot the latch element B upon the track20, I provide a seriesof spaced openings 84,!r upon 1theiiatattaching'flange 24 of the track 20.`

Through' the two flanges28 of eachlatch element B, I likewise' provide a series of'openings 3e. Y

The openings 34 are spaceda greater distance apart than are theopenings 36, the purpose ofA which lwill Vbe hereinafter `more fully set forth. i
