Definitions

  • This invention relates to a driving mechanism for translating a partial angular rotary movement of a manually operable driving member into a full cycle of movement of a driven member, and particularly relates to a driving mechanism for acash register, a calculating machine, or a similar machine, adapted to impart a full cycle of rotation to the main shaft of the machine by reciprocation of an operating handle through a smaller angle.
  • the object of the present invention to provide a manually operable driving mechanism in which the speed of rotation of the main shaft is maintained at a substantially constant rate during the change-over of the direction of reciprocation of the operating handle,
  • the invention comprises a driving mechanism for translating a partial angular rotary movement of a manually operable driving member into a full cycle of movement of a driven member, and includes driven devices coupled to the driven member and a driving device on the driving member which is adapted differentially to engage the driven devices so as to communicate a unidirectional movement to the driven member irrespective of the direction of movement of the driving member.

  • the boss 14 is provided with a central counterbore adapted to receivetherein a shouldered retaining screw, 16, the threadedend of which is receivable within a threaded boring in one end of a hub 19, which has its other end journaled in the machine right side frame 10.
  • he hub-carried lugs 15 are received in rectangular apertures 17 (FIGS. 1 and 2) in an. operating plate 18, secured on said one end of the hub 19, the operating plate 13 and the hub 19 being urged clockwise, as seen in FIG. 1, by a strong spring2t) connected between the plate18 and an appropriate stud (not shown) in the right side frame 11?.
  • a pawl-carrying framework comprising a, pairof similar plates 21 and 22 secured together in a spaced-apart relationship by an intervening hub 23, which hub 23 is pinned on the hub 19.
  • a short shaft 24 journaled between the outer endsof the plates 21 and 22 is a short shaft 24 having oppositely-facing pawls 25 and 26 (see also FIG. 1) secured to the left-hand and right hand ends thereof, respectively.
  • the plates 21 and 22 are further secured together in spaced-apart relationship at their outer ends by a spacer 27, free on the shaft 24.
  • a bracket 40 (shown in dot-and-dash lines in FIG. 1) is suitably secured to the outer side of the machine right side frame 10 and is provided with a central boring suitably engaging and supporting a precise zone of the hub 19.
  • a stop stud 41 extending into the path of movement of a pair of angularly-spaced-apart ears 18a and 1812 on the operating plate 18, is secured to the bracket 40, so as to limit rocking movement of the said operating plate 18 and the .in-
  • the plate car 18 is normally held in cooperation with the stop stud 41 under the influence of the spring 20.
  • clockwise movement of the pinion 34 drives the interconnected gears as and 37 and the shaft 39 counter-clockwise, rotation of the gear 37, through the meshing gear 33, driving its associated disc 31 idly clockwise.
  • afull peripheral surface thereof is positioned beneath the nose of the associated pawl 26 positively to prevent disengagement of the other pawl from the notch a under the influence of the spring 28 when the pawl-carrying framework passes beneath the horizontal center line of the hub 19.
  • the ratio of the gearing of the instant invention is so arranged that the ninety-degree movement of the operating handle 11 in its counter-clockwise, operating, direction imparts a (likewise counter-clockwise) one-hundredand-eighty-degree movement to the shaft 39, and the restoring movement of the operating handle 11 in the other (clockwise) direction imparts an additional one-hundredand-eighty-degree movement in the same (counter-clockwise) direction to said shaft 39.
  • this latter movement of the shaft 39 in the same direction is through'the gear 37 thereon being in direct mesh with the disc-carrying gear 33, all in the manner now described.
  • the plate 18 Upon release of the operating handle 11, the plate 18 is restored immediately clockwise under the influence of the spring 20, carrying with it, through clockwise rotation of the interconnected hub 19, the pawl-carrying framework. Asthe operating pawl 26 is now in engagement with the notch 31-11, the disc 31 and its interconnected gear 33 are caused to be driven clockwise, in turn driving the gear 37 and the shaft 39 counter-clockwise.
  • the gear 36 at such time drives the pinion 34 clockwise, and the pinion 34, through its intermeshing gear 32, drives the associated disc 30 idly counter-clockwise until the ear 1801 again contacts the stop stud 41 to arrest movement of the operating plate 18.
  • the mechanism is prepared for imparting a further three hundred and sixty degrees of movement to the shaft 39, inasmuch as, upon a further counter-clockwise operating movement of the handle 11, counter-clockwise movement of the plate 18 and the hub 19 causes the pawl-carrying framework to rotate counter-clockwise,
  • the full periphery of the disc 31) or 31 prevents the engaged pawl from becoming operatively disassociated from its notch when the pawl-carrying framework is moved either above or below the horizontal center line of the hub 19 to effect change-over of the direction of rotation in Which said pawls are urged by the spring 28.
  • the camrning action is effected, for instance, by the initial clockwise movement of the pawl-carrying framework, after it has been moved fully counter-clockwise, causing the rear surface of the pawl 25 to engage and be cammed clockwise by the rear surface of the notch 30a, which movement is communicated to the pawl 26 by the short shaft 24 to cause the latter pawl to engage the notch 31b.
  • the stop stud 41 is positioned on the bracket below the center line of the driving mechanism and coopcrates with surfaces 18a and 18b formed as shoulders or ears on the operating plate 18.
  • the operating plate 18 is provided with a further pair of surfaces 180 and 18d so arranged as to contact a resilient cup-shaped member 42 suitably secured to a boss 43 on the bracket 40 just prior to the stop stud 41 being engaged by either ear surface 18a or ear surface 1%, thereby to prevent shock as the stop stud 41 is engaged by said ear surfaces.
  • Each of the notches 30a and 39b is formed as a ratchet tooth engageable by the operating pawl 25, it being understood that the notches ?illa and 3112 (not shown in FIG. 3) are similarly shaped so as to be engageable by the operating pawl 26. In this arrangement, the change-over of engagement of the pawls 25 and 26 is effected solely by the spring 28.
