As thus illustrated, the invention comprises a for latching and unlatching the door. No manhasp composed of a relatively short section I and ual adjustment of the latch-piece 5 is necessary a relatively long section 2, in the form of fiat when the hasp section 2 is forced into latching plates, with a hinge 3 provided between them. position, as the latch member 5 and I0 is pushed The section I may be fastened by screws to the upward, and it is then allowed to drop downward door, or to the building, depending upon which by gravity into latching position. Of course, way it is desired to use the device. The relatively when the device is unlatched to open the door, long section 2 of the hasp is flat and straight and the portion 5 is then manually raised until the is provided with avertical slot 4 adjacent the end lower end of the hook or nose I 3 is above the 15 thereof. lower edge of the slot 4, so that the hasp section The latch member or strike-piece is composed 2 may then swing outwardly, and permit the door of the outer portion 5 that has an opening 6 for to be opened. a padlock and has a bevel I to engage the lower Thus, a swinging hasp-plate is provided with edge of the slot 4, when the hasp is pushed into a vertical slot, instead of a horizontal slot, in 0 latching position. The inner end of the portion order to obtain an automatic latching action, 5 has two projections B that are inserted through when the padlock is not used, for latching the the holes 9 of the plate It, and then riveted over, door in closed position, the latch-piece 5 having so that the portions 5 and it become rigidly convertical reciprocation in the said slot. nected together. A plate H is bent to provide a It will be seen that the knuckle of the plate 2, 5 raised portion having a vertical slot l2 in which as shown more clearly in Fig. 3 of the drawing,

extends inwardly and around and back of the pintle l5 of the hinge, and then outwardly and around until the end of the metal meets the body of the plate. With this formation, therefore, the plate 2, where it terminates in the said hinge, engages the edge 16 of the plate I, so that said edge forms a fulcrum against which the plate 2 bears, with the result that a considerable leverage is exerted, so that flexing or bending of the plate 2 is comparatively easy in order to force it into position to engage the retaining edge i3 of the latch-piece, so that the latter will hold the hasp plate 2 under tension. This results in an outward pull on the latch-piece 5, which may be called a strike-piece, and this tension tends to keep the door tightly closed when the hasp is in latching position, and tends to prevent rattling and accidental unlatching of the hasp. Normally, as shown in Fig. 3, when the hasp is in latching position the plate 2 is spaced a distance from the raised portion of the plate II, and the plate 2 is at an angle to the plate I, instead of being parallel therewith.

Furthermore, it will be seen that the knuckle 3 is formed by a reduced end portion of the plate 2 that extends around and behind the pintle I5 and then in front of the latter until its end I! practically engages its base, so that the latter is in position to engage the fulcrum l6 shown and described.

What I claim as my invention is:

1. A combined hasp and latch device, comprising a bracket plate, a swinging hasp plate, a hinge between the ends of. said plates, and means forming a stop at said hinge, to limit the swinging motion of the hasp plate, so that in latching position the hasp plate is slightly flexed and under tension, said stop permitting flexing throughout the entire length of the hasp plate, said hinge comprising a pair of spaced knuckles integral with said first mentioned bracket plate, with said stop formed by an edge extending between the knuckles, and said hasp plate having a single knuckle disposed between said spaced knuckles, with said edge engaging the inner side of said single knuckle.

2. A structure as specified in claim 1, comprising a pintle for said hinge, said single knuckle being formed by an end portion of said hasp plate that extends inwardly back of said pintle, in the latching position of the device, and then around in front until its end terminates at its base portion.

3. A structure as specified in claim 1, said edge being in the plane of the flat outer surface of. said bracket plate, and the point of engagement of the hasp plate with said edge being in a plane parallel with but spaced a distance from the plane of the fiat inner surface of the hasp plate.
