  • An electric switch 64 is fixed on the angle iron 62 and comprises a pair of switch contacts A and B mounted on resilient blades 70, 71 and 72, 73 respectively (FIG. 4).
  • the blades 71 and 72 carry at their free ends stud members 74 and 75 adapted to co-operate with the guiding ring 41 on the rod 32 andthe rounded surface 46 of the block 45 respectively.
  • a second lock 80 is mounted on the bottom wall12 of the case.
  • the second lock 80 is, for example, a tumbler lock having a substantially L-shaped bolt end portion 82 with legs 83 and 84.
  • An upstanding portion 87 perpendicular to the bottom wall 12 is provided at the free end of the leg 84 and has an appended portion which is large enough to co-operate with member 52.
  • the operation of the lock device according to the invention is as follows In the closed condition of a compartment provided with the present lock device, (Flg. the bolt 17 is received in the catch G such that the flange 30 is substantially in line with the stud 74, the ring 41 co-operating with this stud.
  • the switch contacts A and B are in their closed position, and an electrical signal indicating this condition may be transmitted to the control panel which is in front of the clerk.
  • member 52 is in the position in which the end of the elongate portion 55 faces the appended portion 88 on the end portion 82 of lock 80 and the stepped portion 59 is substantially in line with the upperpart 0f the flange 30.
  • the opening of the compartment by the actuation of the lock per se 50 is not possible since the translatory movement of the end of the bolt 19 in the direction of the arrowfis prevented by the abutting cooperation of the flange 30 with the stepped portion 59.
  • the user In order to be able to open the compartment, the user must request the clerk to make the lock device operative.
  • the actuation of thelock 80 causes the displacement of the end portion of the bolt 82 thereof along the direction f and the appended portion 88 in co-operation with the elongate portion 55 brings about the pivoting of the unlocking member 52 in order to pass the stepped portion 55 over the flange 30 the operation of the bolt 17 by the lock 50 is thus made possible.
  • the position is that shown in FIG. 6 in which the user can open his compartment.
  • the member 52 is held in its unoperative position and is maintained in this position by the co-operation of the flange 30 with the edge 58 on the elongate portion 55.
  • the ring 41 fixed to the flange 30 which is displaced in the direction of the arrowfis no longer facing the stud 74 the contact A is open and the contact B, the stud 75 of which is out of engagement with the rounded surface 46 remains closed.
  • An electrical signal of the opened condition of the compartment may be transmitted 'to the control panel at the'surveillance station.
  • the head 38 is in its retracted position, the flange 30 being in contact with the front face of the abutment 45.
  • the spring 40 is in its unbiased condition.
  • the unlocking member 52 is maintained in the same upper position as shown in FIG. 6 by the upper surface of the plate 48 and not by the upper surface of the flange 30.
  • the distance between the flange and the plate is such that in moving the end portion of the bolt 18 in the direction j, opposite the arrow f, the plate reaches the edge 58 of the elongate portion 55 of member 52 substantially at the moment the flange leaves this edge.
  • the flange 30 by bearing against the rear portion of the guiding ring 41 drives the rod 32 with its end carrying the tip 36 visibly beyond the side wall 13 as does the bolt 17 owing to the operation of the key in the lock 50.
  • the stud 74 engages the ring 41 and the stud engages the abutment 45 so that the contact A is closed and the contact B is opened which signals the clerk in charge of monitoring the .strong room that the compartment has not been closed if (see FIG. 8) the switches A and B are arranged in series in a circuit including the coil of the electromagnet 58 in addition to a push button or the like for controlling the coil of. the electromagnet 58, together with an audio or visual indicator.
