SASH FASTENER.

Application filed July 24, 1925.

The present invention relates to a sash fastener and has for one of its objects to provide a simple, substantial, cheaply manufactured sash fastener which is adapted to be secured to the window sash and which is provided with two fastening members, one engageable with the casing to fasten the lower sash and the other engageable with the upper sash to fasten same against open- 1 ing movement in unison with the lower sash.

Another object of the invention is to provide a fastener of the character described by which either the upper or lower sash, or both, may be fastened against opening movement, whether partially open or closed and at any intermediate point between full opening or complete closure.

A still important object of the invention is to provide a sash fastener of this nature which is fairly reliable and eficient in operation, strong, durable, not likely to easily become out of order, and otherwise well adapted for the purpose for which it is designed.

lvith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawinga Figure l is a fragmentary view of a win dow casing and sashes showing my fastener structure associated therewith,

Fig. 2 is a section taken substantially on the line 22 of Fig. 1, and

Fig. 3 is a detail perspective View of the fastener structure.

Referring to the drawing in detail, it will be seen that A designates the window casing or frame having slidable therein in the usual manner the lower sash B and the upper sash C. A base plate 5 is formed from a single sheet of metal and is cut out at two points as is indicated at 6 and 7, the portion being cut out is then rolled whereby sleeves 8 and 9 are formed.

The axes of these sleeves 8 and 9 are disposed rectangularly to each other, the axis of the sleeve 8 being extended over longitudinally with the plate 5 while the axis of the sleeve 9 extends transversely of the plate 5. At one end of the plate 5 there is provided a reduced extension forming a tongue 10 which is bent downwardly to extend into Serial No. 45,868.

the channel provided on the side of the lower sash B to receive the sash cord. On one side edge of the base plate there is provided a lateral extension bent downwardly to form the flange 11. It is not necessary to use any fastening elements as the tongue 10 and flange 11 will prevent the baseplate 5 from becoming accidentally removed from the lower sash B.

A U-shaped jack 12 has its intermediate portion rotatable in the sleeve 9. Another U-shaped jack 13 has its intermediate portion rotatable in the sleeve 8. As is shown to advantage in Figs. 1 and 2, one leg of the jack 13 is longer than the other leg and is disposed at a slight angle thereto. The ends of the U-shaped jack 12 are adapted to straddle the sash cord of the lower sash and to engage the casing A so that if an attempt is made to lift upwardly on the lower sash, a cam action will take place so that the ends of the jack 12 bite into the casing and:1 prevent upward movement of the lower sas o The jack 13 has its ends engageable with the upper sash G. As will be seen to advantage in Fig. 2 when the sashes are new and relatively tight, the shorter leg of the jack 13 will engage the upper sash first and should an attempt be made to move the sashes relative to each other, this movement will tend to swing the jack 18 and bring the end of the longer leg into engagement with the upper sash. If the sashes are loose and worn then the longer leg of the jack 13 will engage.

It is thought that the construction, operation, and advantages of this invention will now be clearly understood without a more detailed description thereof. It will be apparent that the device will efficiently prevent unauthorized movement of the sashes from the outside either when they are fully closed or partially and fully opened.

The present embodiment of the invention, of course, has been disclosed merely by way of example, and in actual practice it attains the feature of advantage enumerated as desirable in the statement and the above description. Numerous changes in the details of construction and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
