HINGED HASP FASTENING Filed NOV. 27, 1951 vxmhr A 4 M ATTORNEYS United States Patent Oflice Patented Sept. 25, 1956 2,764,444 I-ILNGED HASP FASTENING Charles William Cheney, Hockley, Birmingham, England Application November 27, 1951, Serial No. 258,351 Claims priority, application Great Britain April 11, 1951 2 Claims. (Cl. 292-281) The invention relates to hinged hasp fastenings of the kind used with slidable-bolt locks on attache and suitcases and the like and which hasp fastenings are constructed mainly of sheet metal.

It is known to construct such a hasp of two parts, the one an attachment plate and the other a staple member hinged to the plate by a transverse hinging pin, and in this construction it has been proposed to flange the boundaries of both plate and member and to provide upon them co-operative pairs of hinging lugs and hood structures, the latter rigidly extending between the pairs of lugs, through which the hinging pin passes, and overlying each other.

Cheneys United States Patent 2,054,360 of September 15, 1936, describes and illustrates such a construction, and the present invention is an improvement of this construction of fastening by including between the attachment plate and the staple member a pivoted and hooded rigid link whereby the hasp fastening becomes a threepart one suitable for use on all existing makes of attache and suitcases built up of varying thicknesses of material whereby varying surface levels have to be dealt with to which the hasp fastening must be applied.

Accordingly, the invention provides a hasp member which will accommodate itself to varying levels of surfaces and comprising a combination of three permanently hinged parts hereinafter fully described with reference to the accompanying drawings and particularly pointed out in the appended claims.

The accompanying drawing illustrates the invention in desirable form.

Fig. 1 is a side elevation of the fastener in normal position.

Fig. 2 is a side section showing diiferent positions of the three component parts.

Fig. 3 is an underside plan of Fig. 2.

Fig. 4 shows in side elevation a further position of the three component parts of the hasp fastener.

The attachment plate 1 is of rigid form with boundary down turned flange 2, hood portion 3, opposite hinging lugs 4 and 5 being provided at ends of hood portion 3 and rivet holes 30 for fixing the plate to a lid of a travel case.

The hasp 6 is of rigid construction having boundary flange 7, hooded portion 8, end lugs 9, 10 to the hooded portion and also a rigid staple 11.

The link 12 is of rigid construction and comprises a hooded body 13 with opposite flanged ends 14 and 15, this hood being left open at 16 and 17. The hooded body 13 is of a size to overlap the hood portions 3 and 8 of the plate 1 and hasp 6 when the three component parts 1, 6 and 12 are assembled by the hinging devices as hereinafter described.

The hasp 6 and the link 12 are hinged together by the hinging pin 18 which passes through the lugs 9 and 10 of the hasp and through the closed ends 14 and of the link 12 and is afterwards riveted up at 19 and 20. A coil spring 21 surrounds the pin 18 and operates by its arms 22 and 23 between the plate 1 and the hasp 6 to normally swing the plate and hasp into a fly off position as shown in Fig. 1.

The plate 1 is hinged to the link 12 by the opposite hinging studs 24 and 25, axes of the hinges 18, and 24 and 25, being located in parallel planes.

It will be appreciated from the above description that by connecting the hasp 7 to the attachment plate 1 through the intermediary of the link 12, it is possible satisfactorily to compensate for the following diiferent conditions met with when a travel case is closed, viz:

1. When the lid and body of the case are flush.

2. When the lid overlaps the body to approximately half the depth of the bolt member.

3. When the lid overlaps the body to a depth which is approximately equal to the depth of the bolt member.

4. When the lid overlaps the body to a depth which is greater than the depth of the bolt member.

I claim:

1. A spring-loaded hasp fastening of the kind described, combining a rigid attachment plate having thereon a pair of opposite side lugs coupled across the plate by a rigid hood-like structure; a rigid hasp member having upon its back a rigid staple and upon its side a pair of opposite side lugs coupled across the hasp member by a rigid hood-like structure, a rigid link of hood-like structure having side lugs to engage the respective pairs of lugs and the hood-like structures of the plate and hasp member; hinging devices arranged on parallel axes and serving to hinge together permanently said plate, hasp member and link and to permit said hasp member and said link to have swinging movement limited by contact of the hood-like structures, and spring means applied to the said hinging devices and acting on said attachment plate, hasp member and link so as to cause said hasp and said link to move with a fly-oif action relatively to said plate.

2. A spring loaded hasp fastening made of sheet metal of the kind used on attache and suitcases and the like, comprising the combination of an attachment plate having upon its back a rigid boundary flange extending at right angles to the plate and terminating at the inner edge of the plate in a pair of opposite side lugs rigidly coupled across the front of said edge by a hooded structure, a rigid hasp member having upon its back a staple and a rigid boundary flange both extending at right angles to the hasp member and which flange terminates in a pair of opposite side lugs rigidly coupled at the front of the plate by a lateral hooded structure, a rigid link provided at opposite ends with hooded structures and having opposite rigid side lugs corresponding to the respective pairs of lugs and the respective hooded structures of the attachment plate and hasp member, so that one hooded structure overlaps another hooded structure, hinging devices passing transversely through and engaging said lugs and serving to hinge together said attachment plate, said link and hasp member for permitting limited swinging movement of said hasp and said link up to stops formed by the hooded structures, and spring means applied to said hinging devices and acting on said attachment plate, hasp member and link.
