wnmow' FASTENER.

Application flled ll'anuary 15, 1926. Serial No. 81,554.

. tensioned latch carried by the upper andlow er ends of the window sashes for cooperation with keeper members carried by the upper and lower ends of the window frame, the latches being automatically moved into their locking positions with the operating handles therefor' to effect the release thereof being employed as gripping members in lieu of the usual socket or hook to facilitate raising and lowering movement of the sashes.

With the above and other objects in view that will become apparent .as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described,shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a front elevational view of a. window frame with the two sashes slidable therein equipped with the fastener constituting the invention,

Figure 2 is a fragmentary front elevational view of the window frame and lower sash with the latter in its partially elevated position,

Figure 3 is a detail sectional view taken on line 3-3 of Fig. 1 showing the upper sash fastener showing the apertured operating handle to receive the window rod to effect release of the fastener,

Figure 4 is a detail sectional view taken on line H of Fig. 1 showing the lower sash fastener,

Figure 5 is a sectional view taken on line 55 of Fig. 4 showing the coil springs associated with the fastener for placing the same under tension,

Fi ure 6 is a erspective view of the latch mem er of the astener,

Figure 7 is a perspective view of the keeper member,

Figure 8 is a perspective view of the boxlike casing enclosing the fastener and removed from the sash rail, and

Figure 9 is a fragmentary front elevational view of a windowshowing the latch member at one side of the Window with a a vertical series of keepers for holding the wlndow at different elevations.

The window fastener disclosed in thisap-,

plication being adapted for association with the upper ra l of an upper window sash and the lower rail of a lower window sashwith devices cooperating therewith carried by the upper and lower sides of the window frame, the detail description of one of the fastenerdevices will cover the several illustrated with one exception hereinafter to be noted. As illustrated in Fig. 1,'the window frame embodies side bars 1, asill 2 and a head bar 3. Upper and lower window sashes 4 anu 5 respectively are slidable in the window lower face of the sash rails 6 and 7 with the bottom side thereof open as shown in Figs. 8 and 4. Openings 12 are formed in the top wall 8 of the casing for the passage of fastening devices 13 to anchor the casing in position.

Each fastener includes a latch member illustrated in detail in Fig. 6 and comprises a shaft 14: carrying a collar 15 adjacent each end with the opposite ends of the shaft j ournaled in the openings 16 formed in the end walls 9 of the casing. The latch per se is of V-shape in end elevation with the crotch thereof enclosing the shaft 14 and secured thereto as by welding or the like, the latch embodying a plate handle 17 and a latch head 18 carrying an outwardly directed latch.

to the head bar 3 and sill 2 in a position to be received through the open lower side of the casing when the window sashes are in their closed position and to be engaged by the latch flange 19, the keeper being shown in detail in Fig. 7 and is in the form of an elongated block 21 carrying apertured base flanges 22 for the passage of fastening devices 23, the block 21 tapering upwardly and carrying an angularly directed keeper flange 24 at its upper edge. The latch flange 19 is influenced in a direction toward the rear wall 10 of the casing for latching engagement with the keeper flange 24 by the coil springs 25 associated with each end of the shaft 14: at opposite sides of the latch memher, one end 26 of each spring being anchored to the adjacent end wall 9 of the casing while the other end 27 0f said spring engages the latch head 18.

When the lower sash 5 is in the closed positions shown'in Figs. 1 and 4, the plate handles 17 are elevated and disengage the latch flange 19 from the keeper flange 24: against the tension of the springs 25, the plate handles 17 being employed as gripping devices for raising the lower sash. lVhen pressure on the handles 17 is relieved, the coil springs 25 automatically cause the handle toengage the lower wall of the slot 20 in the front wall of the casing and position the keeper flange 19 for automatic latching engagement with the keeper flange 24 upon the block 21. In releasing the up per latch member, a window rod is employed and the usual hook carried by the window rod is engaged in the opening 28 provided in the plate handle 17 as illustrated in Fig. 3.

As shown in Figure 9, the side bars 1 of the window frame are provided with a vertical series of keepers 24 with which the latch .17 carried by the adjacent edge of the window is associated, so that the window can be retained in different elevated positions.

While there is herein shown and described the preferred embodiment of the present invention, it is, nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What is claimed is In a window fastener, a sash rail having a recess therein, an open sided casing set into the recess with the open side thereof disposed adjacent the window frame, a latch keeper on the window frame in position to be enclosed by the casing when the sash is closed, a tensioned latch carried by the sash to automatically engage the keeper, the front wall of the casing being set flush with the front wall of the sash and having an opening therein, a handle for the latch extending through the wall opening, said latch being of plate formation and V-shaped in end elevation, one wall constituting the handle, a latch flange on the other wall, a shaft journaled at its opposite end in the casing to which the latch is rigidly secured, collars fixed to'the shaft adjacent each end to engage the end walls of the cusing to prevent axial movement of the shaft, and a coil spring on each end'of the shaft between the latch and casing with its opposite ends engaged with the latch and casing to position the latch for automatic engagement with the keeper.

In testimony whereof I afiix my signature.
