3 Claims.

This invention relates to closure fasteners.

An object of the invention is to provide a closure fastener wherein the handle of the fastener is so supported as to normally coact with a 5 strike plate to fasten the closure, but can be disengaged from said strike plate at will simultaneously with the manipulation of the closure by means of said handle.

Other objects and advantages are to provide a closure fastener that will be superior in point of simplicity, inexpensiveness of construction, positiveness of operation, and facility and convenience in use and general efiiciency.

In this specification and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms; and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

The invention is clearly illustrated in the accompanying drawing, wherein I Fig. 1 is a sectional side View of the closure fastener, the closure being shown in broken lines.

Fig. 2 is a front elevation of the closure fastener.

Fig. 3 is a side view of the bracket of the closure fastener.

In carrying out my invention, I make use of a hollow bracket 6 which is suitably secured to the movable part of the closure, such as a rail 1 of a window. In the present illustration the bracket 6 is fastened to the lower rail of the window. A strike plate 8 is secured to a fixed member of the frame surrounding the closure. In the present illustration the strike plate 8 is secured to the window sill 9 in registry with the bracket 6.

The bracket 6 has flanges I I and a hollow body l2 of substantially U-shaped cross section, with the open side extended over the strike plate 8. A pivot pin I3 is held transversely across the bracket 6 in the side walls of the hollow body I2. n the pivot pin I3 is pivotally supported a tubular extension 14 on the end of a suitably curved handle Hi. The opposite sides of the tubular extension I4 have elongated slots ll therein which are slidable upon the pivot pin l3. The end of the tubular extension l4 adjacent the rail 1 is closed by a threaded plug I8. A coil spring H) in the tubular extension I4 bears against the pivot pin l3 at one end and against said plug l8 at its other end so as to normally urge the free 1935, Serial No. 23,340

end of the extension l4 toward the rail 1 at a slight incline away from the window sill 9.

The handle 16 has an abutment shoulder 2! above the extension l4 which abuts against a lug 22 inside of the top wall of the hollow body I2 to limit the movement of the extension [4 toward the raill. The handle also has a rounded projection 24 extended from its lower side, which fits into a rounded keeper notch 26 formed on a keeper 2T protruding and inclining from the strike plate 3 upwardly and away from the rail 1, to provide a guide face 30.

In operation, the handle is gripped and pulled away from the rail 1 and the sill 9 against the action of the respective springs, so as to disengage the projection 24 from the keeper notch 25. Then holding the handle in the disengaged position the same is pushed'past the strike plate 8 as the window is opened. When the handle is released it is returned to its normal position by the said spring action. By reason ofthis resiliently yielding pivoting of the handle, the projection 24 is allowed to ride on the inclined guide face 30 of the strike plate 8 which leads up to the keeper notch 2E. "The projection 24 is then snapped into the notch 25 by reason of said spring action on the handle, and thereby automatically holds the fastener in fastening position whenever the closure, such as the window, is shut.

Having thus described this invention, what I claim and desire to secure by Letters Patent is:

1. A closure fastener comprising a casing for attachment to a closure, a latch having one end portion of the same extending into said casing and having an exterior portion shaped in the form of a handle, a portion formed on one side of the latch and adapted to engage a stationary strike, a pin and slot connection between the easing and said latch, and a compression spring disposed within said one end portion of the latch and serving to oppose outward movement of the latch relative to the casing.

2. A closure fastener comprising a casing for attachment to a closure, a latch having one end portion of the same extending into said casing and having an exterior portion shaped in the form of a handle, a portion formed on one side of the latch and adapted to engage and hook upon a stationary strike, a pin and slot connection between the casing and said latch, and a compression spring disposed within said one end portion of the latch and serving to oppose outward movement of the latch relative to the easing, and towards said strike.
