Definitions

  • an axially extending bar is caused to be inserted into the channel defined by the aligned notches by rotation of the selector axle which in turn causes the movement of a locking plate from a locking to an unlocking position and at the same time causes the pivoting of a member to Which the axially extending bar is attached into a position Whereat the bar is inserted into the aligned notches.
  • the feeler axle is longitudinally, reciprocatingly acted upon to move a plurality of toothed racks vertically a predetermined distance, which toothed racks are caused to be in meshing engagement with said toothed disc. The predetermined movement of the toothed racks establishes the preselected position of notches on the discs whereby the axially extending bar can be received therein.
  • the lock which forms the subject of this patent application offers, among other advantages, that of preventing its being possible to determine by acoustical means and with a certain degree of approximation the combination established for the opening of a safe.
  • the lock in question is not subjected to any great mechanical force, due to the fact that it limits itself to blocking the mechanical mechanism for opening the doors of safes when the said door ought to remain closed, and to free the said mechanism
  • it is desired to open the door by acting on the series of levers and belts which are normally moved by means of a Wheel or lever of the appropriate dimensions to support the mechanical eflFort which the displacement of the bolts supposes.
  • the basic principle of the lock for which patent application is being made consists in causing a series of strips to be displaced through a pre-established number of steps, thereby causing the rotation of a series of discs through angular magnitudes proportional to the displacements of the corresponding strips, the discs remaining in such a position that they all present a notch which is cut in their periphery in a position facing a bar Which under these conditions can penetrate and displace a piece which acts as a stop which blocks the movement of the handoperated bolt for opening the door on which there is fixed the lock which is the subject of this patent application.
  • step by step displacement of the strips the object of which is to cause to rotate also at fixed angular steps the discs with which they mesh may be replaced by the angular displacement of a wheel, the movement forward of which can be eifected either by means of a projecting piece or a pawl fixed on a suitable rotating arm.
  • FIG. 1 represents the inner face of the lock, which is accessible only to the owner of the safe once the door has been opened.
  • the left-hand side of the same shows the outer face of t lock and door.
  • the knob or selector axle 1 has an axial recess in which there may be displaced a feeler knob 2 which forms a solid part with a bar 3 which is fixedly attached to a wedge 4 whose bevel surface 5 is supported on the rectilinear part 6 of the recess 7 of a feeler plate having a cross-piece 8.
  • Wedge 4 is received in the orifice 9 of the cover of the lock and is restrained from rotation due to the projecting piece 10 on the cover which fits into the groove 11 of the wedge 4.
  • the sliding movement of the knob 2 and the wedge 4 is independent of the rotational movement of the knob 1.
  • the ratchet 13 in the form of a polygon turns thus overcoming the action of the tongue 14 which is pressed by the spring 15 against the ratchet 13 to cause the knob 1 to occupy stable positions in its rotation.
  • the rotation of the whole complex is limited by the escape wheel or ratchet 16 and pawl 17 operated by the corresponding spring.
  • Each tooth of the escape wheel 16 corresponds to the retention of the knob 1 in one of its stable positions with the exception of that which corresponds to the last position Which it can occupy. As can be seen in the draw ing, this last position does not correspond to any tooth facing the pawl 17. This makes it possible to impart a short turning movement to the knob in the direction given by the arrow 18, which turning movement is termed in this description as a trip turn.
  • the bevel 5 On pressing the knob 2, in accordance with what has been previously explained, the bevel 5 is pushed against the edge 6 of the cross-piece 8, which in turn moves in an upward direction.
  • the two projecting members 25 and 26 of cross-piece 8 moves upwardly thereby engaging the two pivots 27 (only one of which is seen in the figure) of the plate 28 to which is also attached the common axis or pivot 23 of all the levers 21 on engagement of the pivots 27 by the upwardly moving members 25 and 26.
  • the plate 28 moves upwardly.
  • the upward movement of the plate 28 causes the levers 21 also to move upwardly and the engagement of the tooth 24 of the lever 21 with the tooth portion of the strip 25 causes the strip 25 also to move upwardly thereby overcoming the action of the restraining springs 29.
  • each strip 25 is engaged by a toothed wheel 37 provided with a notch 38 and causes said wheel 37 to rotate a predetermined distance to a position shown in dotted line 39.
  • said bar 40 which is fixed on a lever 41 will enter into the aligned notches 38 of the discs 37 on the downward movement of plate 44 to which lever 41 is operatively connected by means of pin 42 being in camming engagement with the oblique groove 43 of plate 44.
  • the said plate 44 can slide downwardly pulling in its downward movement a block 45 which in its raised position blocks the hand-operated mechanism for opening the door.
  • the said block is shown by dotted lines in the figure since it falls towards the inner side of the lock 9.
  • the downward movement of the plate 44 is brought about by pressing and imparting to the knob 1 a movement in the direction of the arrow 18 which causes the rotation of the escape wheel 16 to the position shown in the figure wherein the pawl 17 is facing the most widely spaced tooth thereof.
  • the knob 1 in order to open the door it will be necessary for the knob 1 to occupy the first stable position and to press the button 2 the number of times previously determined so that the first of the strips 25 and the corresponding disc 37 may occupy such a position that the recess 38 is situated facing the rod 40.
  • the knob is then moved, in the direction shown by arrow 12, to a second stable position which is determined by the tongue 14 pressing against the pawl 13.
  • the groove 19 of the axis 32 turns and separates the corresponding lever 21 so that its tooth 24 disengages the strip 25 which is retained in position by the tooth 33.
  • a new notch 19 faces a new lever 21, the tooth 24 of which engages a new strip 25 and a new wheel 37.
  • the button 2 is pressed as many times as may be necessary in accordance with the setting previously made so that the new disc 37 may be caused to move its notch to face the rod 40. This operation is continued until the relevant combination has been effected, at which moment the wheel 16 will now permit the small trip turn represented by the arrow 18.
  • a safety lock comprising a plurality of superposed discs each having a notch and a toothed portion on the circumferential edge thereof, an axle on which said discs are freely rotatably mounted, a plurality of toothed strips, one for each of said discs, and each having a toothed portion on one edge thereof engageable with the toothed portion of one of said discs, and a toothed portion on the opposite edge thereof, a plurality of levers, one for each toothed strip and each having a tooth thereon engageable between the teeth of said toothed portion on said opposite edge of said strip, and a finger portion spaced from said tooth, a lever carrying plate on which said levers are pivotally mounted in superimposed position, said lever carrying plate being vertically reciprocally movable, a rotatable selector axle having a knob on one end thereof and extending between the space between said teeth and said fingers on said levers and provided with a plurality of grooves axially and circumferentially spaced from each other and adaptable to
  • the safety lock of claim 2 including a pawl means resiliently engaging a toothed escape wheel mounted on said selector axle, the teeth of said Wheel corresponding to the rotational positions of said selector axle defined by said ratchet and tongue means with the angular separation, one pair of said teeth being greater than the angular separation of the remaining teeth thereon to permit rotation of said selector axle in said second direction.
