The front a<1> and lid a<2> are preferably released electrically. A bolt carried by a spring plate is mounted upon the lid a<2> and engages a recess or link carried by the box a, an electromagnet being adapted to withdraw it and thus release the lid and front of the box, allowing them to fall into the position shown. An alarm bell or bells may be simultaneously rung. In a modifi. cation, shown in Fig. 3, two doors i, i<1> normally lie flush with the wall and are opened by springs when a retaining-bolt is withdrawn. In a further modification, the box is closed by a spring rollershutter.
