Although such a door is ground to its seat on j amb b, with a perfect, practically air-tight fit, efforts have nevertheless been made to introduce liquid explosive-matter between the two, sufficient space having been forced by suitable implements like a peening tool, or by hammerblows directed against the front of the safe close to the edge of the door-opening which would cause the metal thereat to bulge and force it out of shape until a gap of a size, sufficient for the purpose, was produced. The door is locked in its closed position by sliding bolts J, which when projected into corresponding sockets prevent its rotation for unscrewing, and which are actuated in the usual way by a lever mechanism controlled by a time-lock which is contained in a casing y'. A cover H, incloses these parts with eX- ception of a shaft g, on pinion G, which projects through the same and permits application of a crank for operation of the geartrain, to seat or unseat the door. Rotation is accomplished by means of a set of gearwheels, the larger one E, of which is rigidly secured to the door, a boss f, being provided upon which it is mounted, the smaller one, a pinion Gr, being supported on circular frame (l. The door may be rotated in its bearing in either one of these positions to effect engagement, or disengagement, as the case may be, of the complementary parts of its screw-connection. This door-bearing is carried on a crane-frame E, supported by hinges e, on the front-wall of the safe and by means of which frame the door is swung into or out of its opening.

The door, to enable it to enter or leave its screw-seat, must be rotated, for which purpose a journal D, is provided on its front-side, which is fitted for support into a bearing constituted by a circular frame d, in a manner to be free for rotation therein. The complementary parts of this connection are provided, one O, on the door, and the other c, in the door-opening back of jamb ZJ. Means like a screw-connection are presumed to be used for keeping the door seated in its j amb and which require rotation of the door, to seat or unseat it.
The edge of the door is tapering and j amb to which it is fitted is shaped correspondingly.
