Definitions

  • This object is attained according to the invention by providing a combination lock with a code number setting knob adapted to unlock the lock by alternate rotation of the knob in opposite directions and by thus consecutively setting a rotatable graduated disc to predetermined numbers, which combination lock comprises means for operatively coupling the setting knob with the graduated disc when the knob has been rotated in the prescribed direction the prescribed number of times.
  • These coupling means may take various forms.
  • the coupling means are embodied in coupling pawls and entraining discs or rings which sequentially entrain each other when the setting knob continues to be turned, until one of said entraining rings operatively engages the coupling pawls connected with the graduated disc when the setting knob has been rotated the prescribed number of times.
  • the entraining rings as well as the graduated disc are rotatably mounted on the hub of the baseplate of the setting knob, the setting knob itself being preferably rotatably mounted in the hub of the baseplate of the setting knob.
  • the invention greatly facilitates setting and resetting the combination lock without in any way reducing its safety and efiiciency.
  • the graduated disc of the combination lock is not itself rotated in the direction of to tation of the setting knob until the latter has been rotated the required number of times for opening the lock. Rotation of the setting k-nob together with the graduated disc is then continued until the first number of the code registers with the index mark.
  • the knob is then again rotated in the first direction and the graduated disc set to the third number of the code. Rotation in the opposite direction will then open the lock. This procedure naturally applies to a lock which operates by the selection of three numbers. If only two 3,209,567 Patented Oct. 5, 1965 numbers are required the setting knob need merely be rotated once in one and once in the opposite direction.
  • FIG. 1 is a top plan view of the setting knob, entraining rings and coupling pawls, shown at the instant of entrainment of the graduated disc in one direction, the cover plate having been removed to reveal the mechanism;
  • FIG. 2 is a vertical section taken on the line IIH of FIG. 1 including the cover plate
  • FIG. 3 is a top plan view of the setting knob, entraining rings and coupling pawls shown at the instant of entrainment of the graduated disc in the contrary direction, the cover plate having been removed to reveal the mechanism, and
  • FIGS. 4 to 11 are plan and corresponding side views of the individual entraining rings.
  • FIGS. 1 and 2 show a rotatable graduated disc b and a circular base plate a with a central hub a
  • Rotatably located in the hub a is a selector or setting knob c.
  • This knob c has a radially extending portion 0 which may form, as shown in the drawing, part of a cover with a lug 0 which engages in a slot d in an entraining ring d rotatably mounted on the hub a Therefore, when the knob c is turned to, the left, the entraining ring d will be forced to participate in this rotation by the engagement of the lug 0 with the slot d
  • a lug d (FIGS. 4 and 5) on the entraining ring at is carried against a tooth e (FIG. 6) on a second entraining ring 2 and carries this ring around with it.
  • a lug g on the ring g strikes a tooth h (FIG. 11) of a ring h which is thus likewise entrained.
  • a tooth in on the ring h now raises a coupling pawl i pivotally mounted on disc b (FIGS. 1 and3) and, forces a tooth i thereon into engagement with the tooth g of the ring g (FIG. 1,).
  • Operative connection is thus established between the setting knob c and the graduated disc b which therefore now participates in the. further rotation of the knob c.
  • the knob c has been turned through three complete revolutions so that the lock can be correctly set by stopping the graduated disc 12 at the first appropriate number.
  • the setting knob c is now turned in the opposite direction.
  • the extending portion 0 and the lug 0 again entrain the ring d.
  • the lug d on this latter ring now strikes a tooth e (FIG. 6) on the ring e and a tooth f (FIG. 7) on the ring 1, entraining both rings.
  • the knob c is again rotated in the opposite direction, i.e. to the left.
  • the knob 0 again carries the two rings d and e with it to the left by means of its extending portion 0 and the lug 0
  • the hookshaped tooth 2 now strikes the tooth k of the coupling pawl k and causes operative connection to be established between the knob c and the graduated disc b, this disc b now being entrained after only onerevolution of the knob c.
  • the required number of the disc b is now turned into register with the index mark. A further rotation of the knob c to the right to its stop will now open the combination lock.
  • the number of reversals of the knob need not be counted. They necessarily arise when setting the lock for opening the same and when resetting to different code numbers.
  • said coupling means are coupling pawls connected with the graduated disc and entraining rings, said entraining rings being arranged to entrain each other sequentially when the setting knob continues to be turned until one of said entraining rings operatively engages the coupling pawls connected with the graduated disc when the setting knob has been rotated the prescribed number of times.
  • a lock according to claim 8 wherein said fifth ring is provided with a tooth engaging one coupling pawl to move the latter in a direction so that a tooth on the fourth entraining ring makes entraining contact with a tooth of a coupling pawl, when the knob continues to be turned in the same direction.
  • a lock according to claim 10 wherein the second tooth on the third entraining ring is moved into entraining contact with a tooth on one of the coupling pawls.
