1 Claim.

This invention relates to closure fasteners. An object of the invention is to provide a fastener which can be readily manipulated as a closure is opened and closed, respectively, to release and fasten the closure to its closure frame.

Particularly it is an object of the invention to provide a closure fastener adapted for use in connection with a window to fasten the window to its window frame in closed position and to unfasten the window simultaneously with the opening of the window when the window is pulled open by means of the fastener handle; the window fastener is also adapted to hold a usual shade cord or curtain cord thereon allowing the swinging of the shade or curtain with the window.

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 conven- 20 fence in use and general efficiency.

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 claim following the description, it is desired to cover the invention in whatsoever form it may be embodied.

This invention is clearly illustrated in the accompanying drawing, wherein- Fig. 1 is a sectional view of the closure fastener, showing a fragmental section of a window and window frame on which the fastener is assembled.

Fig. 2 is a front view, partly in section of the closure fastener assembled on the window.

Fig. 3 is a detail View of the handle, and

Fig. 4 is a detail view of the bracket of the fastener.

In the herein illustration the closure fastener is shown in use as a window latch, and it includes a keeper hole. 6 preferably located on the inner edge of the upper cross jamb or rail 7 of a window frame. Over the keeper hole 6 is secured an apertured strike plate 8 recessed into said edge of the cross rail 7 so that it faces the outer or top edge or side 9 of the top rail ll of a window which covers the enclosure of the window frame.

A hollow guide I2 is secured in a recess 1 3 in the top rail H so as to slidably confine therein a belt it substantially at right angles to the strike plate 8 and in alignment with the keeper aperture of the strike plate 8. The bolt I 4 is suitably curved and pointed at its end adjacent I pivot pin 22.

to the keeper 6 so as to offer a longer, inclined strike surface H5 at the side which approaches the strike plate 8 when the window is closed. Near the other end of the bolt I4 is a transverse bore or cavity IT in said bolt M. The side of the guide i2 is provided with an elongated slot 18 on the face thereof adjacent the inner face of the window. On the face of the window rail ll ad jacent said guide I2 is suitably secured a bracket H] which has parallel, spaced lugs 21 extended therefrom. A pivot pin 22 is held in said lugs 2i substantially parallel with the face of the rail i i.

On the pivot pin 22 is supported a handle 23 which extends on the outside of the pivot spaced from the face of the window. The handle 23 has a bifurcated hub formed in the shape of a yoke 24. The legs of the yoke 24% extend along the inside face of the respective bracket lugs 2i and have pivot holes 26 therein through which the pivot pin 22 extends to form the fulcrum of the handle 23. It is to be noted that the handle 23 is so curved that it protrudes above its fulcrum and is curved down to the yoke 24. From the top of the yoke 24 extends an extension or arm 21 substantially at right angles to the general plane of the handle 23. The arm 21 extends through the guide slot l8 and into the bolt cavity H. The end 28 of the arm 21 is rounded but fits the height of the cavity I! so that it reciprocates the bolt [4 in the guide l2 as the handle 23 is swung around its fulcrum.

In the space between the legs of the handle yoke 24 is positioned a sheave 29 rotatable on the Inasmuch as the yoke 24 is open toward the pane of the window, in other words toward the opposite or bottom rail of the window frame, not shown, a cord 3! may be played around the usual groove of the sheave 29. The cord 3! is the usual control for a window shade or curtain that is mounted on said opposite or bottom rail of the window not shown.

In operation the window may be swung open or shut together with a curtain or shade mounted on one of its rails and the shade cord 3i held on the latch handle 23 on the opposite rail. The window is swung open by pulling the handle 23. When the handle 23 is pulled, first it turns away from the face of the window around its fulcrum thereby moving the arm 21 and the bolt i4 away from the strike plate 8 until the bolt It is disengaged from said plate 8. Further pull on the handle 23 will swing the unfastened window into open position. As the window is shut the inclined face I6 of the bolt 14 strikes the outer curved end of the inclined strike plate 8 and urges the bolt inwardly of the guide 12 until the bolt I4 is opposite the keeper hole 6. The weight of the handle 23 normally urges the arm 21 and the bolt l4 upwardly toward the strike plate 8. If necessary then by a slight push on the handle 23 toward the window the bolt I4 can be firmly engaged with its keeper to fasten the window in place,
