The movable hinge strip I is hinged by means 20 of a pin 2 to a fast strip 3. On the inside! of the movable hinge strip I a shoulder stud 4 having a conical head 5 is ?xed and besides a flat spring I2 attached at one end and standing off from the plate I with the other end. Two plates 6 and 25 ‘I set apart at a certain distance from each other and held together to form a pocket are sunk into the front side of the trunk and inside of this pocket a U shaped spring having the ends of its legs projecting to the outside of the pocket is 30 held in position by a pin 8. This spring bears with its two arms against a stop pin I9 which keeps said arms separated from each other in close proximity of round openings I 0 provided in plates 6 and ‘I. When closing the hinge strip the head 35 5 is pressed against the two arms of the U-shaped spring 9 the latter are spread apart, snap in behind the shoulder I I of the head 5 ?xing there by the movable hinge strip I and locking up the box. On the inside of the fastening strip a spring 40 I2 is ?xed. The free ends I3 of arms of the spring 9 are extended into a recess provided in the trunk wall outside of the base plate 1, loops I6 being provided in said ends, which will regis ter when the trunk is closed with a loop I4 formed 45 by the rolled up end of the movable strip- I. The opening of the trunk is effected by pressing the ends I3 of the spring 9 together to release the head 5. In this moment the hinge strip I is repelled by the spring I2 of the hinge strip I 50 so that a self acting opening of the fastening takes place. from handling during transport and the opening can always be effected without any tools. Applicant is well aware that U shaped springs or spring controlled clamps closing upon a head ed stud have already been used before and were 20 released either by hand or by a pressure upon certain parts of the structure. Applicant does not claim such mechanism as such, but the combina tion of a particular form of such a spring with 25 a hasp fastening for trunks and with means to protect the same against rough handling dur ing transport. What I claim is; In a hasp fastener for trunks, boxes and the 30 like of the kind having a. hinge strip the movable member of which may be locked by spring arms embracing a shouldered head and in combina tion, the movable member of the hinge strip hav ing a loop formed at its extreme end for sealing 35 purposes and a stud provided with a conical and shouldered head ?xed to the inside of said mem ber, a pocket formed of two plates held at a distance from each other, with holes in said plates to receive said stud and struck into the 40 front wall of the trunk, a pivot inserted between said plates and a V shaped spring held by said pivot and arranged to embrace said stud with its legs which extend to the outside of the pocket to permit being gripped when opening the hasp, 45 and a stop pin between the plates and between‘ the legs of said spring to keep the legs of the lat ter separated to permit introducing the conical head of said stud, all substantially as described. 50 HECTOR FRIDOLIN BAERFUSS.
