Definitions

  • COMBINATION PADLOCK The invention relates to combination padlocks, and is more particularly directed to improvements in combination padlocks of the type including means for setting or changing the combination.
  • a combination padlock made in accordance with the invention comprises a body having an internal cavity and a plurality of spaced slots in communication with the cavity.
  • a dial provided with indicia or numbers is positioned in each slot.
  • a shackle of the usual type, or having a long portion and a short portion, is mounted on the body so that the long portion extends into the internal cavity of the body. As usual, the shackle is movable to first open position and a second closed position. 1
  • One end of the body is provided with means to receive the end of the shackles short portion in the closed position of the shackle.
  • a sleeve for each of the dials is mounted on the long portion of the shackle with the sleeves in abutting, end to end relation.
  • the sleeves are secured to the shackle so that they cannot move linearly on the'shackle.
  • the shackle is rotatable with respect to the body, and the sleeves may rotate upon the long portion of the shackle.
  • Each dial and its respective sleeve are provided with cooperable means to separably key the dials and sleeves to one another.
  • Blocking means is provided for cooperation with each sleeve to prevent movement of the shackle, or to maintain the device in locked condition (off combination).
  • the sleeves are provided with means which allows the blocking means to be by-passed (on combination), thereby allowing linear movement of the shackle from open to closed position and vice versa.
  • the essential shackle is used to change the combination; no additional parts are required to accomplish this function.
  • the device is constructed to allow the further inward movement of the shackle to a third or combination changing position; that is, movement further inward than to close the padlock.
  • the cavity of the body within which the long portion and the sleeves thereon are positioned is of sufficient length to allow the shackle to be displaced inwardly a greater distance than to the second or closed position. Due to the aforesaid orientation of the shackle, the end of the short portion may move alongside and below the adjoining end of the body. The dials may then be rotated to a combination of ones own choice, following which the sleeves are returned into keyed engagement with the dials.
  • An object of the invention is to provide a combination padlock which eliminates obtrusive means for changing the combination.
  • Another object of the invention is to provide a combination padlock having a minimal number of parts considering the fact that the lock also permits setting to a combination of ones own individual choice.
  • a further object of the invention is to provide a combination padlock including means for changing the combination, the padlock being constructed to permit substantial miniaturization.
  • Still another object of the invention is to provide a combination padlock wherein the shackle is utilized for the additional function of setting or changing the combination; and further, wherein the shackle is related to its associated parts so that the shackle is moved in an inward rather than an outward direction when changing the combination to thereby reduce the possibility of inadvertently changing the combination when it is desired to simply open the lock.

  • notches 68 are spaced around the outer circumference of the dial between adjacent numbers or indicia.
  • the notches on each dial cooperate with a detent 70 on a spring arm 72 which extends from the base portion 73 of the dial cooperable means E.
  • the dial cooperable means is stamped and formed from a metal having spring properties, and the part is made with a number of arms equal to the number of dials.
  • the part is held in place by a holding member 74 which extends from the body member 20, the end of the projection pressing the base portion 73 against the adjoining wall of the opposite body member. This arrangement prevents the dials from spinning freely; the rotation of the dials, and the sleeves, is controlled.
  • each sleeve has a central bore 76 of a diameter slightly greater than the diameter of the shackle.
  • the outer diameter of the sleeve is provided with a plurality of circumferentially spaced, longitudinally extending teeth 78.
  • the teeth extend longitudinally for a distance less than the length of each sleeve, whereby a shank or base portion 80 of reduced diameter is provided for a portion of the sleeves length.
  • Each sleeve is provided with nine teeth.
  • One tooth is omitted to furnish by-pass means 82.
  • the by-pass means comprises a segment in the toothed portion, and has a diameter the same as the diameter of the shank 80.
  • the body A is provided with means cooperable with each sleeve to prevent movement of the shackle, or to maintain the device in locked condition.
  • the body is provided or cast with a plurality of longitudinally spaced blocking means in the form of projections 84a, 84b and 84c.
  • the blocking projections extend into the cavity 34 for selective cooperation with the teeth 78 and with the by-pass means 82.
  • the padlock is on combination.
  • the shackle may be moved from the closed position of FIG. 3 to the open position of FIG. 4 and vice versa.
