Figure 1 is a top edge View of a fragment of a screen door showing the latch of the invention in a latching position,
Figure 2 a detail view of the latch removed from the door,
' Figure 3 a longitudinal sectional View taken on the plane indicated by the line 33 of Figure 2,
Figure 4 a transverse sectional View on the plane indicated by the line 44 of Figure 2, and 30 Figure 5 a front View of the latch keeper.
In the drawing similar reference characters will be used to designate corresponding parts throughout the several views.
The improved door latch comprises an attaching plate 1 that is adapted to be secured to the screen or other door A by screws or other driven fastenings engaged through openings 2 in the plate 1, and having ears 3 formed on the plate, preferably by bending 40 tongues extending from the plate back thereon as clearly shown in the drawing.
' tongue secured to attaching plate 1 by means Serial No. 68,616.
The latching plate 4 has an extension 5 on each of its edges engaging in the ears 3 and provided with tongues 6 bent back on the extensions 5 to form the pivots for the plate 4. Plate 4 has a reduced portion 4", and this reduced portion is bent laterally to form a hook 7 and then returned from said hook portion 7 as shown at 8, and the extremity of the reduced portion 5 is formed with a so cylindrical loop 9 that serves as a finger hold for actuating the latch from a locked to -an unlocked position. 10 is a rectangular opening in the latch plate 4 and 11 a spring of a rivet or other suitable fastening 12, the end of the spring tongue 11 engaging a wall of the opening 10, and the purpose of the spring 11 is to normally move the latch plate 4 into latching position. 5 13 indicates a keeper plate that is adapted to be secured to the door jamb B by screws or other suitable fastening members inserted in openings 14 in the plate, and one edge of the plate is bent as shown at 15 to engage the hook portion 7 of the latching plate 4 to latch the door and hold it in closed position.
WVhat is claimed is: A latch, comprising a plate of sheet metal for securing the device in position, tongues on said plate bent to form spaced apertured ears, a latch member having an opening therein, extensions on said plate bent to formpintles pivotally engaging said cars, a hook formed on said plate, and a leaf spring secured to the first mentioned plate and engaging a wall of said opening and normally tendingto hold the latch plate in latching position.
In testimony whereof I affix my signature.
