A cross-bar of an improved description for safes or bank vaults, doors, &c, has been invented by F. C. Goffin, of New York City, who has taken measures to secure a patent. In this improvement the cross bar is hinged in the middle, one half being fixed and the other movable, and fits when closed either into a groove or flanches, so arranged that its outer surface shall be flush with the door. The object of this is to prevent the possibility of its being forced by any instrument, to which this kind of security, as at present employed, isfvery liable, and as an additional safe-guard the cross-bar is bolted on the inside, by means of a lock fitted to the door, which is operated from the outside. The ordinary cross-bar is merely placed against the outer surface of the doors, and is secured by a padlock, which, as well as the cross-bar may be easily forced or wrenched off by a lever. But by this arrangement there is no way that the cross-bar can be drawn back, and as it is so placed as to cover the key-hole of the safe lock, the latter cannot be exposed otherwise than by picking the lock of the cross-bar.
