G. E. HANSON AUTOMATIC WINDOW SASH FASTENER Filed Dec. 5, 1925 Patented 7 Nov. 9, 1926.
UNITED PTENT Fries.
AUTOMATIC WINDOW-SASH FASTENER.
Application filed December The invention relates to means for securing the upper and lower sashes of windows and has for its object the provision of a fastener that is automatically operated by the closing of the window so that the two sashes will be secured from reopening.
The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawings, in Which- Figure 1 is a front viewof a fragment of the upper and lower sashes of a window showing the improved fastener in position,
Figure 2 a vertical sectional View on a plane indicated by the line 2-2 of Figure 1, the fastener being shown in secured position in full lines, and in an unsecured position in dotted lines,
Figure 3, a horizontal sectional view on a plane indicated by the line 33 of Figure 2, and
Figure 4: a view in perspective of the locking member.
In the drawings similar reference characters will be used to designate corresponding parts throughout the several views.
The upper sash of a window is indicated at A, and the lower sash at B. The improved fastener comprises a plate 1 that is adapted to be secured to the upper rail of the lower sash B and has an upstanding flange 2 on which is pivotally mounted an arm 3 that is offset as shown at 4. The latch member 5 is pivotally secured to the arm 3 as shown at 6 and has a notch 7 in its front ed e.
WVhen the window sash is open thelatch member 5 assumes the position shown in dotted lines in Figure 2, being seated on the corner 13 with the rear edge of the latch member 5, indicated at 14:, in a substantially vertical position. When the window is closed the lower rail of the upper sash A 3, 1925. Serial No. 72,983.
engages the end of the set screw 10 and lifts the arm 3 on its pivot 3 and as the pivot 6 is arranged 011 the other side of the center of gravity of the latch member 5 from the corner 13, it will be apparent that the latch member 5 will be tipped into engagement with the side rail of the upper sash A, and will engage the keeper 11 as shown in full line position in the drawings, Figures 1, 2, and
When it is desired to unfasten the window it will be necessary to manually move the latch member 5 out of engagement with the keeper 11 and the sashes may then be opened and the latch member will assume the position shown in dotted lines in Figure 2 until the sashes are again closed. It will be apparent that one of the advantages of the invention is that the fastener being automatic it is particularly adapted for windows having high sashes, such for instance as in public halls, churches, etc., thus obviating the necessity of climbing a ladder to secure the windows, and as it will be possible to unfasten the window by means of a pole having a hook, the windows may be operated expeditiously.
It will also be understood that the fastener cannot be operated from the outside as is the case with a great many of the fasteners now in use so that burglary will be discouraged.
W hat is claimed is 1. A sash fastener comprising an arm adapted to be pivotally mounted on the top rail of a lower sash and movable by engagement with the lower rail of the upper sash, and a latch plate pivotally engaging said arm and moved into and out of locking engagement with the upper sash by movement of said arm, and a keeper to be secured to the side rail of said upper sash to engage said latch plate.
2. A sash fastener comprising a plate adapted to be secured to the top rail of a lower sash, an upstanding flange on said plate, an arm pivotally secured to said flange, said arm having an extension adapted to be engaged by the lower rail of an upper sash, a set screw engaging said extension, a lat-ch member of substantially trian gular shape pivotally secured to said arm, and a keeper adapted to be secured to the upper sash and to engage said latch member.
3. A sash fastener comprising a plate adapted to be secured to the top rail of a tower sash, an upstanding flange on said plate, an arm pivotally secured to said flange, said arm having an extension adapted to be engaged by the lower rail of an upper sash, a set screw engaging said extension. a latch member of substantially triangular shape pivotally secured to said arm, a notch in one edge of said latch member, a stop 011 said flange, and a keeper adapted to be secured to the upper sash and to engage said latch member. 7
In testimony whereof Ivaffix my signature.
GEORGE EMIL HANSON.
