Abstract

A plurality of walls form a housing cavity in which a latch hasp is received. An opening in the housing receives therethrough the latch hasp, the latch enclosing the cavity. The bolt seal has a shank with a head at one end or with a U-shaped bight in a second embodiment. The head engages a housing wall and a locking body engages and locks to the shank at a shank end distal the head. The shank between the head and lock body is fully enclosed by the housing and latch to preclude access to the shank by tampering tools. In a second embodiment, the shank bight engages the received hasp of a latch. The shank distal the bight is locked to the housing by a locking body. The latch depends into and encloses the housing cavity open at the top. The shank between the bight and the locking body is fully enclosed in the cavity. Different housings are disclosed wherein the head may be enclosed or exposed for access by a shank breaking tool. A reusable bolt and locking body is disclosed for use with several embodiments.

said bottom plate member comprising a V-shaped member with its apex closest to and facing in a direction toward said top plate member for forming a recess for receiving said locking body.

7. The device of claim 6 wherein certain of the housing walls cooperate with the bottom plate member for surrounding said recess and said received locking body.

8. A protection device for a bolt seal including a U-shaped shank having a bight and a locking body for releasable attachment to a shank end portion distal the bight and for a latch hasp having an aperture for receiving the shank bight comprising:

a housing having a cavity with a top formed by front and rear walls, a pair of opposing lateral side walls and a bottom plate member, said cavity at the top forming an opening for receiving said hasp, said latch for enclosing said opening, said walls, plate member and latch for enclosing said cavity to preclude access by tampering tools to the hasp and to the shank in said cavity, said bottom plate member having an aperture for receiving and passing therethrough said end portion for receiving said locking body in locking engagement;

said bottom plate member having a rear portion lying in a plane normal to said side, front and rear walls and a front portion lying in a plane inclined relative to said front and rear walls, each said rear and front portions having a corresponding aperture for receiving a different shank end.

9. The device of claim 8 wherein said bottom plate member receives a shank end distal the end portion.

10. The device of claim 8 wherein the rear wall and a portion of the side walls depend below the bottom plate member so as to form a protective recess for said locking body.

11. Protection device for a latch hasp having at least one aperture and a bolt seal comprising a shank and a head secured to the shank at one shank end and a locking body selectively locked to an opposing shank end for locking the hasp therebetween, said device comprising:
