- FASTENER FOR WINDOW SCREENS, STORM WINDOWS, AND 'THE LIKE Filed Nov. 15, 1944 INVENTOR.
Patented Dec. 6, 1949 FASTENER FOR WINDOW SCREENS STORM WINDOWS, AND THE LIKE Homer 0. Davis, Kalamazoo, Mich.
Application November 15, 1944, Serial No. 563,544
This invention relates to improvements in fasteners for window screens, storm windows and the like.
The main objects of this invention are:
First, to provide a fastener for storm windows,
screens and the like which may be used interchangeably for either, and one which is easily engaged and effectively secures and supports the screen or window.
Second, to provide a fastener of the type described which has a wide range of adaptation in use and one which can be economically produced as an integral stamping unit.
Third, to provide a fastener for these uses which is very easily manipulated to attach or detach the screen or window frame or other parts to be secured together which are disposed in angular relation.
Fourth, to provide a fastener having these advantages which is highly effective, is well-hidden from the outside, and prevents opening a window or screen from the outside.
Objects pertaining to details and economies of the invention will definitely appear from the description to follow. The invention is defined.
in the claims.
A fastener embodying the features of the invention is clearly illustrated in the accompanying drawing, in which:
Fig. 1 is a fragmentary perspective view of a window frame or casing and associated storm window with my improved fastener in operative relation thereto.
Fig. 2 is a plan view of the blank from which the fastener is formed.
Fig. 3 is a fragmentary section on line 3--3 of Fi 1.
In the accompanying drawing l represents a window frame or casing and 2 the check stop thereof. 3 is the sash of a storm window although it will be understood that it may be the sash of a window screen. The sash 3 is designed to fit within the window frame or casing I against the check stop 2 as clearly shown in the drawing. This is a common arrangement in window screens and storm windows.
My improved fastener designated generally by the numeral 4 comprises a pair of plates 5 and 6 disposed in an angular relation to each other and desirably formed as an integral stamping. The plate 5 engages the sash 3 of the window and constitutes a sash engaging plate, and the plate 6 engages the check stop 2 of the frame or casing I and constitutes a check stop engaging plate. These plates have inturned flanges I at their upper ends formed with mitered abutting edges 8 and preferably welded together as. indicated at 9. These flanges form cross braces, the
bracing effect being'considerably enhanced by the welding. This welding permits the use of quite light stock.
The plates '5 and 6 are provided with longitudinal keyhole slots l0 and II, the slot ll of the plate 6 being inwardly inclined toward the plane of the plate 5, and the slot I0 is disposed parallel to the plane of the plate 6. The enlargement l2 of the slot H is laterally offset while the en'- largement 13 of the slot i0 is symmetrically disposed.
The sash 3 is provided with a screw M which constitutes a headed stud while the stop 2 is provided with a screw l5, also constituting a headed stud. It will be noted that the slot ll extends substantially below the lower end of the slot Ill. The purpose of this is to permit the'supporting engagement'of the fastener with the stud IE, or screw I5 prior to the positioning and engagement of the sash 3 and the engagement of the stud H! with the. slot l0. After the engagement of both studs the fastener is driven down, the flange 1 constituting impact receiving members; that is, they may be struck with a hammer or tool to drive the fastener down. Owing to the inclination of the slot II the sash 3 is drawn firmly against the stop and the fastener is subjected to such friction that it remains in its engaged position. Owing to the slot ID in the sash engaging plate 5 being parallel to the plane of the check stop engaging plate 6, there is no tendency for the sash being bent or broken away from the supported pane of glass when fasteners on the opposite sides of the window are driven to tightly engaged position. To release the fastener the flanges may be struck from the under side, which effectively disengages the fastener.
One set of fasteners may be used for both storm windows and screens or, if desired, the fasteners may be entirely removed when it is not desired to provide a window with storm sash or screens.
Y It will be apparent that the fastener cannot be disengaged from the outside without breaking the window pane or cutting the screen. In the event a window or screen sash is warped or twisted, it can ordinarily be straightened and clamped in place by using more of the fasteners than would ordinarily be required.
I have illustrated and described my invention in what I consider to be a very practical embodiment thereof.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A fastener blank for window screens, storm windows and the like composed of an integral blank of bendable sheet material having upper and lower edges and opposite side edges, and stud receiving slots disposed generally vertically and slightly inclined towards each other and -di. s posed throughtiit "slibs tafitial bortiois "bf their lengths in side by side relation, said slots being laterally spaced from each other to permit the blank being bent vertically intermediate the slots into plates disposed angularly relative is eath other, and 5a recess extending inwardly from the flipper edge of the blank and disposed vertically ,over the por: tion of the blank intermediate said slots to permit the upper edge portion of the blank being sent outwardly to provide impact receiving means plate, s t-1 a pistes hating 19-" w \ih n; at i s, .l r giflg W gitiidliial st u'd reserving smears- 5 any 'side remade pnraughbqts ibsg inan er the r lengths, the slot 6f "the c'h'ckfsto e gagmg plate being inc-lined t wardsft e p oi" the sas engaging plate, a drag slot 01 the sash engagi piste b'eing parallel to we plaiiepf' the check step erradapted to receive the heads of studs, the slot of the sash engaging plate being parallel to the plane of the check stop engaging plate, the slot of the check stop engaging plate being inwardly inclined towards the plane of the other plate and extending substantially below the lower end of the slot in the other plate, its enlargement being offset inwardly, the enlargement of the fsiojt of tl'ieother plate, being symmetrically disposed relative to the slot.
4. A fastener for window screens, storm winglows and the like comprising integral plates disposed in angular relation to fit in the angle reselling from the positioning of the sash of a window screen 0;; storm window against a check stop, one of said plates constituting a check stop engaging plate and the other constituting a sash engaging plate, said plates having longitudinal keyhole -slots, the slot of the sash engaging plate being parallel to the plane of the check stop tan rine, b a i l 1 i h ckj op en a ing plate being inwardly inclined towards the plane of the otherplate and extending below'the slot of t-h e other plate to permit supporting engagement r the fastener with a check stop prior to the po'sitioning of a slipportedmember and engagement or the fastenejr therewith, said slots being disposed in side by side relation throughout substantially their entire lengths.
