Fournier, Fitchburg, Mass. Application September15, 1936, Serial No. 100,933 (Cl. 292-62) 1 Claim. This invention relates to improvements in means for fastening and securing window screens or storm Windows to window casings and the primary object of the invention is to provide com 5 plemental interlocking ñxtures which when ap 8 and storm window 9 to be set in place against *Y or within the window casing. To this end, each side frame I0 of the screen is provided with an opening or recess II so located therein as to be positioned properly adjacent the Window casing 5 plied to the window sash, screen, and storm Window, respectively, enable the screen and storm windows to be interchangeably placed on the sash in proper and intended position whenever recess 3 when the screen is in place against the casing as shown in Figure 7. Disposed over each recess II and fastened to the screen frame by 10 desired and without use of tools or any major alterations in sash, screen or window. A further object of the invention is to pro I2 for a cup I3, the latter being housed Within and snugly fitting the recess in the manner illus trated. A comparatively short pull rod or pin I4 extends into the cup through a central opening screws or other suitable fasteners is a cover plate vide interlocking ñxtures which are substantially permanent when once fastened to the window in the cover plate and at its inner end is con 15 casing and to the screen and storm Window with nected with a disc or washer I5 contacting the sides of the cup and serving as a cross~head or which they are to be used. An additional object of the invention is to guide for steadying the rod in its movement in wardly and outwardly of the cup. Mounted on provide a spring locking device for securely fas tening and holding the window or screen in place the outer end of the pull rod and turning about the axis of the latter is a keeper engaging- ele 20 20 by spring tension. With the above object in view my invention ment comprising a flat plate having a rounded residesin the novel construction,arrangement and -nose latch portion I6 and a reduced portion I'I, the latter serving as a single hold or grip and combination of parts h-ereinafter more fully de scribed With reference to the accompanying draw .~ being curved as shown to accommodate the linger. Rod I4 may be either fixed to the keeper en 25 ings wherein: Figure l is a plan View from the inside of a gaging element to turn therewith or the said ele ment may be loose on the rod to turn freely window casing and screen provided With inter thereon. Concealed within the cup and encircling locking fixtures in accordance with the presen invention. 30 > Figure 2 is a plan view of one of the side frames of the window casing showing keeper plates with arcuate cam slots. Figure 3 is a view similar to Figure l but show ing the screen replaced by a storm window. Figure 4 is a View in front elevation of a side 35 frame of a window casing showing a keeper plate with an angular cam slot. Figure 5 is a vertical central section of the part shown in Figure 4. Figure 6 is a detail View of the latch unit to be 40 aiîixed to the screen or storm window. Figure 7 is a sectional View of adjacent frames ci window casings and screens equipped with and secured together by the improved fastener, the 45 parts of which are clearly shown. For the purposes of this invention, the Window casing I is provided at diametrically opposite points near the top and bottom of the side frames 2 with recesses 3 as shown in Figures 1 and 5. 50 Over each recess is placed a keeper plate 4 fas tened to the casing by screws 5. The portion of the plate overlying the recess is cut out to provide a cam edge 6 and stop slot 'I. 'I'he fastening or latching elements which engage the keeper plate 55 are carried respectively by the particular screen the pull rod with Vone end bearing against the disc and the other end bearing against the cover. plate is a coil spring I8. This spring is tensioned to expand between the cover plate and the disc and normally holds the rod Well Within the cup with the disc bearing end thereof substantially at the bottom of the cup and the latch bearing end close to the cover plate. Thus, in order to fasten the screen to the casing, the pull rod. is necessarily moved outwardly to align the latch element with the cam slot of the keeper and this movement is opposed by the resistance of the spring, which spring resistance is increased in proportion to the spring compression. The spring resistance is overcome in the ñrst instance by the pull of the linger against part I'I until the latch element is turned to cause part IB to enter the 45 keeper slot and bear` against the low portion of the cam edge I6. As the latch travels over the high part of the cam edge, the outward movement of the pull rod continues with further compres sion of the spring until the latch element is ñnally seated in the stop slot. At this time, the parts are positioned substantially as shown in Figure 7 from which it will be apparent that the force of the spring against the washer I5 tends to hold the latch I6 firmly in the stop slot and the 55 2" 2,120,606 spring force acting against the cover plate I2 tends to bind the frame IIJ tightly against the casing 2 to» provide a Weatherproof and insect excluding joint. Due to the fact that screens are generally used over the lower half only of a window casing, for the purposes of the present invention they require of the frame is substantially devoid of unsightly projecting or objectionable fixtures. Having thus described the invention, what is claimed is: Means _for detachably fastening screen and storm window frames in overlapping engagement with an exterior frame of a window casing com but two fasteners for interlocking engagement prising keeper means carried by a part of the with the lower pair of casing keeper elements. inner edge of said exterior frame, a cup carried by the screen or storm window frame and opening 10 10 For full length screens or storm windows four fasteners may be employed as shown in Figure 3. Screens and storm windows are used interchange ably with a common window casing and the com plemental elements of the herein disclosed novel 15 fastener are permanent on the screen and storm window and on the window casing when once properly afiixed thereto. The concealment of the spring and cup Within the body of the frame and the general arrangement and construction ofthe 20 fastener parts provide for a simple compact fastener inexpensive to manufacture and easy to install, the installation being such that the face out on the inner face of said frame, a cover plate closing the open end of the cup and attached to the inner face of said frame, said cover plate having an opening therein, a rod passing through the opening, a washer connected to the inner end 15 of the rod and slidably arranged in the cup, a Vspring encircling the rod and located between the washer and vthe cover plate, a latch plate con nected with the outer end of the rod and having a rounded end for engaging the keeper means, the opposite end being reduced in Width and bowedto form a finger piece.
