.ZPATENT OFFICE HASP LATCH 2 Claims.

This invention relates to latches such as are used on travelling bags, brief cases and the like.

The general object of this invention is to simplify and cheapen latches of this character and toprovide a latch, the hasp of which has a greater range of movement than is commonly found in latches of this character.

A further object is to provide a hasp latch of this character in which the parts may be readily disassembled but in which the hasp is held against any chance of being accidently pulled out of the hasp plate.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawing wherein:

Figure 1 is a longitudinal section of the hasp plate, the hasp itself being shown in elevation;

Figure 2 is a perspective view showing the hasp plate, hasp and spring separated.

Referring to the drawing, l0 designates the hasp plate which is formed as usual of a stamping. This plate is stamped to form a housing II which extends upward from the level of the hasp plate and the outer wall [2 of which is inclined rearward towards the face of the hasp plate. The plate, of course, is provided with the usual openings l3 whereby the plate may be riveted to the bag or other article to which it is attached. The housing II at its front end is provided with an opening l4 defined by the outer wall I 2 of the housing, and the inwardly ex tending lateral walls l5. The body of the hasp plate is extended inward beneath these walls 15 to form the lugs it which project inward slightly beyond the walls l5.

The hasp H, as shown in Figure 2, at its rear or butt end is widened, as at I8, and is notched at 19, these notches extending inward from the side edges of the hasp to thus define pintle lugs 20. The free end of the hasp is provided with the eye shown as constructed in accordance with my Patent No. 1,951,551, granted on the 20th day of March, 1934. The side walls l5 of the housing II are engaged in the notches I9 so that the pintle lugs 20 extend behind the walls I5 and have rocking engagement with these walls. Disposed within the housing is a folded spring 2! having a long curved arm 22 and a short arm 23 approximately half the length of the long arm, the extremity of the short arm being bent or deflected at its end, as at 24. The spring, when in place, occupies the position shown in Figure 1, with the bent portion 24 seating against the lugs IS, the bight of the spring disposed within the housing i and the long arm of the spring extending against the inside face of the hasp I i.

It will be seen that with this construction, the hasp cannot be pulled out accidently because 5 of the fact that the lugs 29 engage against and interlock with the inwardly projecting walls l5 defining the sides of the hasp opening l4. While these side walls and the lugs 20 prevent the hasp from being accidently pulled out, they permit 10 free rocking movement of the hasp, the lugs 26 acting as pintles for this purpose. The hasp can only be detached from the plate It] by removing the spring 2!, shifting the hasp laterally in the opening M as far as it will go and then giving a 15 twisting motion or turning motion to the hasp. By reversing this action, the hasp may be readily inserted in the housing of the plate and when inserted is, as before stated, prevented from accidental removal after the insertion of the spring 20 22 because this spring 22 will prevent any axial turning movement of the hasp and the hasp cannot be pulled out because of the engagement of the lugs 20 with the side walls l5. The spring is held in position by the engagement ofthe slightly bent or curved edge 24 with the lug l6 and the pressure of the spring is sufiicient to prevent any accidental shifting of this spring out of the housing. When the spring is in place, the hasp may be turned inward, that is, toward the plane of the inner face of the hasp plate and the hasp may be swung outward, the end edge 25 of the hasp pressing the long arm of the spring 22 toward the short arm, as will be obvious from Figure 1. Thus, the spring acts to urge the hasp to a normal position as shown in Figure -1.

My construction gives a great range of movement to the hasp, a much greater range than commonly found in devices of this character. 40 Furthermore, the structure is particularly cheap, permitting the parts to be readily stamped out and readily assembled. At the same time, as before stated, there is no chance of the parts being 'accidently disassembled. The hasp cannot be removed from the housing when the housing plate is attached to a bag because the widened portion A8 of the body of the hasp will strike the face of the bag or other article if the hasp be axially turned in an endeavor to remove the 50 hasp, but when the hasp plate is off of the bag, the hasp may be readily removed or inserted 'without trouble. The long arm of the spring plays against the inside face of the hasp H as the hasp is depressed or raised.

It will be noted that the spring cannot be entirely pulled out from the housing and detached therefrom under ordinary circumstances, because the long arm of the spring, if the spring is pulled directly outward, will strike the eye at the extremity of the hasp and thus be prevented from any further movement. However, by fully compressing the spring by an implement, the spring can be pulled out and canted and then be removed, but this cannot occur accidently and Without the exertion of considerable force.

What is claimed is:

1. A hasp latch for bags including a plate having a housing thereon, the housing at one end having a mouth defined by side walls, a top wall and two opposed inwardly projecting lugs at the lower end of the side walls, the hasp having opposed notches in its lateral edges defining pintle lugs and adapted tobe disposed with its notches in register with the side walls of the mouth opening and its pintle lugs extending laterally beyond the inwardly projecting walls of the mouth opening, and a spring folded upon itself to provide a short arm and a long arm, the bight of the spring being disposed within the housing, the short arm resting upon the upper edges of the lugs of the housing and being bent at its end to seat on said lugs of the housing, the long arm extending beneath and bearing against the inside face of the hasp.

2. A hasp latch for bags including a hasp plate having a housing struck up therefrom, the housing increasing in depth toward its front end, the front end of the housing defining a mouth opening having inwardly projecting lateral walls and inwardly projecting lugs at the ends of said walls, a hasp having its inner end widened and provided with opposed notches defining laterally projecting pintle lugs, the notches receiving the side walls of the mouth opening and the pintle lugs engaging behind said side walls, and a spring disposed within the housing and detachably engaged therewith, the spring having an arm bearing against the inside face of the hasp.
