Safe box with anchor chain

A safe box with anchor chain, said safe box including an upwardly opening lower part of appreciable depth and provided with upwardly projecting peripheral walls including a pair of remote oppositely outwardly facing side wall portions, a downwardly opening cover provided with downwardly projecting peripheral flanges including a pair of remote oppositely outwardly facing flange portions corresponding to said wall portions, said cover being positionable over said lower part with said flanges telescopingly engaged over said peripheral walls to close said lower part from above, means operable to releasably lock said cover in position closing said lower part, said wall portions each having a narrow upstanding slot formed therein opening upwardly through the upper free edge thereof, a link chain section composed of interconnected links and including opposite end portions having a first pair of links spaced from the end links of the corresponding end portion terminal ends and removably received downwardly sideways, only, in a corresponding slot, said portions of said flanges closing said slots from above when said cover is in the closed position, a pair of upstanding posts rigidly mounted from and projecting upwardly from said lower part inwardly of and disposed along a path extending between said side wall portions, said link chain section including a second pair of opposite end portion links spaced between the first pair of links and said end links downwardly telescoped over the upper ends of said posts, said cover, when said cover is in the closed position, closely overlying said post upper ends to prevent upwardly withdrawal of said second pair of links from said posts, said path closely paralleling the inner side of a peripheral wall of said lower part extending between said wall portions, an upstanding partition supported from said lower part, extending and secured between said wall portions and closely paralleling the side of said path remote from the last-mentioned peripheral wall, whereby said partition serves to reinforce said wall portions on one pair of corresponding sides of said slots and said last-mentioned peripheral wall serves to reinforce said wall portions on the other pair of corresponding sides of said slots, said flange portions, when said cover is in the closed position, downwardly closely overlapping appreciable vertical extent portions of said side wall portions defining the upper end portions of said slots, whereby said flange portions serve to reinforce said wall portions against outward deflection, the spacing between said side wall portions and the adjacent posts and the spacing between each link of said first pair of links and the adjacent link of the second pair of links being such that said chain section is only slightly slack between each post and the adjacent side wall portion slot.
