WINDOW FASTENER Filed May 26, 1950 IN VENTOR BY QM g Patented Feb. 2, 1954 WINDOW FASTENER- Harold Walter Falk, Minneapolis, Minn., assignor to Wright Products, Inc., St. Paul Park, Minn., a corporation of Minnesota Application May 26, 1950, Serial No. 164,443

2 Claims. 1

My invention relates to an improvement in window fastener wherein it is desired to provide a simple and effective means for locking a window or similar object in place in its frame.

Various means have been provided for locking windows in closed position. Some of these members engage the outer surface of the window to hold it in place. Others are provided on the inside of the window and are particularly useful where a locking of the window from the inside thereof is desirable.

An object of the present invention resides in the provision of a window fastener which is simple and inexpensive to manufacture. Devices have previously been made which adequately serve their intended purpose. However, the cost of production of such items is usually relatively high. Furthermore, the locking arrangement is such that in many instances little difficulty would be involved in pulling the lock open. The present structure more effectively locks the windows than the usual type of device and at the same time the structure may be produced at an extremely low price.

An added feature of the present invention resides in the provision of a lock which may be punched and formed entirely of sheet metal or the like. As a result the structure may be produced with dies upon a punch press for a relatively low cost.

These and other objects and novel features of my invention will be more clearly and fully set forth in the following specification and claims.

In the drawings forming a part of my specification:

Figure 1 is a perspective view of my window fastener showing the same in use.

Figure 2 is a perspective view of one part of my device removed from the window.

Figure 3 is a perspective view of the other main part of my device showing the construction thereof.

Figure 4 is an elevation view of the part illustrated in Figure 3.

Figure 5 is a sectional view through the assembled device showing the manner in which the two parts of the fastener contact when the device is in use.

My window fastener is indicated in general by the letter A. This fastener includes two main parts. The first part may be termed the keeper part and is indicated in general by the numeral Hi. The other part comprises the pivoted lever part and is indicated in general by the numeral l I. In actual practice the keeper part is usually mounted upon a window, a panel, or other movable part. The pivoted lever part II is usually mounted on a fixed part of the structure, as for example upon a window frame. In the drawings the keeper part In is shown fastened to the sash 12 of a screen or storm window l3. 'l he pivoted part II is shown fastened to the storm window frame l4.

' The keeper part ID includes a base panel I5 having one or more apertures l6 therethrough to accommodate fastening screws or bolts such as ll. The base panel I5 is preferably provided along one edge with an operating flange l9 which projects at substantially right angles from the panel l5 for a short distance and then is inclined from its right angular relation along its outer edge as indicated at 20. An elongated slot 2| is provided in the flange l9. The slot 2| permits the flange !9 to be more easily grasped than would otherwise be possible. The slot 2| also permits the insertion of a tool through the device if it is found useful or desirable.

A pair of tapered prongs 22 extend downwardly from the edge of the base panel l5 opposite that bearing the flange l9. These prongs 22 are tapered downwardly and outwardly and are arranged at opposite ends of the base panel. These prongs 22 extend down into the wood of the window sash l2 and tend to hold the keeper part 10 from movement relative to the sash when the screw I1 is in place. Through the use of the prongs 22, the device is held from movement even while supported by a single screw H.

A flange 23 extends upwardly from the pronged edge of the panel I5 between the prongs 22. This upwardly extending flange 23 acts to support a trough-shaped or generally U-shaped keeper 24. The rounded surface of the keeper is directed downwardly toward the sash 12 but the flange 23 holds the base of the trough shaped element in spaced relation to the sash so as to permit the lever part of the device to be inserted between the keeper 24 and the sash in the manner which will be later described.

The lever part II includes a flat body portion 25 which is tapered in form, being relatively narrow at one end 26 and being rounded and enlarged at its other end as indicated at 21. A circular depression 29 is off-set from the remainder of the body 25, this depression 29 having a marginal edge 30 which is substantially on the plane of the remainder of the tapered body 25. The depression 29 is provided with a coaxial aperture 3| therethrough for accommodation of a pivot screw or bolt 32.

The lever body 25 is provided with a flange 33 which projects at substantially right angles to the plane of the body 25 and follows one tapered edge thereof. The flange 33 is provided with a curved end 34 which joins the marginal edge 30 of the circular depression 29 and which extends substantially tangent thereto tor a short distance. The flanged edge 33 is designed toextend beneath the rounded lower surface of the keeper 24 when the lever is engaged with the keeper. A flange 35 projects from the opposite tapered edge of the lever body 25 and also is substantially atright angles to the plane of the body. The flange 35 extends at full width fora short distance from the smaller end 26 of the body 25 and then tapers in thickness as indicated at 35 until it merges with the plane of the tapered. body 25 a bestillustrated in Figures 1 and 3 of the drawings. The flange 35 serves as a means of rotating the lever portion l I In operation the keeper portion H! of my window fastener is usually secured to the window sash or other movable part while the lever part N is pivotally attached to the frame it the pivot bolt 32. The lever portion H is properly positioned so that the curved end 3 of the lever portion may engage beneath the keeper part 24 of the keeper portion [0. By' pivoting the lever it about its center the keeper portion 24 and accordingly the window or other removable part to which it is attached may be drawn againstthe frame shoulder 31 so as to securely look the frame in place.

When the lever has been pivoted downwardly beneath the keeper 2 the pull is such that an outward strain against the window can not pivot. the lever N into open position. other words, the pull? of the keeper upon the lever is such that an outward force tends to hold the lever stationary or to swing the lever toward closed position. As a result the movable part is securely fastened to the frame l4 and can not he accidentally disengaged therefrom.

By merely pivoting the lever part I t in the proper direction the leverpart may be entirely disengaged; from the. keeper M and the movable window or other member may be disengaged from the: frame: ll. If desired both a storm window and: a. screen may be provided with similar keeperelements rem. engage each l'ever'part H Thus either the screen or' storm window may be held in the trainer by my device.

The slottedi flange l9 may be easily" grasped by the fingers; in. placing the: storm sash or screen in position in its frame. This flange thus acts as a: handle by means: of which the storm sash or screen. may be manipulated" a pointinwardly of the: window frame; The angularly bent flange portion 20: and the slot 21 prevent the flange.- from. slipping from the fingers: during this process;

In accordance with the patent statutes, I have described the principles of construction and operation of my window fastener, and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.

I claim:

1. A locking lever for use in conjunction with a window fastener including an elongated flat lever body, a substantially circular off-set portion at one end thereof having an aperture extending centrally therethrough for accommodation of. a pivot member, said off-set portion being on a plane parallel to, and spaced from, the plane of said body, a locking flange along one longitudinal edge of said lever, said flange having a curved end adjoining the lever adjacent to said circular off-set portion, said flange being perpendicular to the general plane of the lever, and a second flange projecting. from said lever body along the opposite longitudinal edge thereof adjacent the other end of the body.

2; A locking lever for use in. conjunction with a window fastener including an elongated flat lever body, a circular oil-set portion atv one end or said body on a plane parallel to and spaced from the plane of the body,v an axial aperture through said circular portion, tapering longitudinal edges on said body one of which substantially tangent to said circular elf-set portion, a flange extending along said tangent edge and extending in a direction opposite the direction of off-set of said circular portion and at substa-ntially right angles to said. fiat body, said flange having a curved end substantially following the curvature of said circular oft-set portion beyond the point of tangency of said. edge for a short distance, and a substantially right. angular extending flange along the opposite longitudinal edge of said flat body, said last named flange extending from said fiat body in av direction opposite the direction of oii-set of said circular portion.
