Definitions

  • the present invention relates to a control mechanism for use in connection with a preselection counter for insuring that, after the counter is rotated to a certain position, figure or number by receiving a preselected number of impulses and has then instigated a particular control function, the counter will be automatically returned by suitable resetting means to its original or zero position and will during the return movement not be acted upon by any further impulses which might interfere with its complete return.
  • the apparatus which are known for accomplishing this purpose generally employ special relays which are sometimes also combined with the counter so as to form a single structural unit. When the particular number to which the counter has been preset is reached, these relays switch off any additional impulses which might arrive and also start the resetting means.
  • a circular disk the peripheral surface of which is provided with a notch
  • a pin, roller, or the like on one end of a lever is adapted to slide or roll along the peripheral surface of the notched disk and to engage into the notch thereof when the preselected number is reached.
  • This lever is operatively connected to a locking member which is associated with two resilient or spring-loaded trip members, each of which is associated with a separate pushbutton switch or the like, the first of which is con nected to a control magnet, while the second is connected into the impulse line leading to the counter and is adapted to interrupt this impulse line.
  • a locking member which is associated with two resilient or spring-loaded trip members, each of which is associated with a separate pushbutton switch or the like, the first of which is con nected to a control magnet, while the second is connected into the impulse line leading to the counter and is adapted to interrupt this impulse line.
  • either the first switch or the movement of the control magnet or of any other movable element of the mechanism may also be employed for starting the resetting means.
  • the bell crank When the control magnet is actuated by the operation of the first switch, the bell crank is pivoted so that its second arm disengages from the trip member of the second switch which thereby interrupts the impulse line leading to the counter so that no further impulses can reach the latter.
  • the resetting means are started which as stated above-rnay be eifected by any of the means of the mechanism which have so far been moved, and the counter is quickly returned to its zero position.
  • This resetting operation is completed at least by the time when the bell crank nears the end of its first pivoting movement from the second toward the first switch when it hits against the trip member of the first switch and presses the same against this switch which is thereby actuated so as to switch off the control magnet which then returns to its original position and thereby also pivots the bell crank back against the trip member of the second switch and actuates the latter so that the impulse line is again opened and any impulses which may subsequently arrive will again act upon the counter to start it again from its zero position.
  • a separate notched disk is connected to each of these wheels.
  • Suitable conventional means for example, a rod or roller of a sufiicient length so as to extend across all of the notched circular disks, may then be provided for insuring that the locking member will not be actuated to disengage from the trip member of the first switch until the notches of all of the circular disks are in alignment with each other and the rod or roller can engage into all of the notches.
  • FIGURE 1 diagrammatically illustrates the control mechanism in a position during the counting operation of the counter and the corresponding rotary movement of the notched disk or disks;
  • FIGURE 2 shows the control mechanism in the position which corresponds to the position of the counter wheel or wheels when arriving at the preselected number; while FIGURE 3 shows the control mechanism in the posi tion which corresponds to the zero position of the counter Wheel or Wheels at the end of the resetting operation.
  • FIGURE 4 shows a switching circuit in which the im- 3 pulse transmission is interrupted also during the declining or dropping time of the resetting magnet.
  • FIGURE shows a switching arrangement for the automatic renewed preselection with interruption of the impulse transmission during the entire time of renewed preselection.
  • the preselection counter has only a single counter or number wheel 1 which is turned by electric impulses and adapted, when it reaches a certain preselected number of angular position, to return automatically to its original zero position.
  • the control mechanism according to the invention which is provided for controlling the resetting movement of the counter and for preventing any impulses from reaching the counter during its return movement comprises a circular disk 1 which is adapted to be positively connected to the counter wheel 1' after being adjusted in the peripheral direction so that a notch 2 in the peripheral surface of disk 1 is disposed in a certain position in a fixed relation to the preselected number on the counter wheel 1.
  • a pin or roller 3' on the free end of a lever 3 which is pivotable about an axis 3 is adapted to slide or roll along the peripheral surface of disk 1 and to engage into the notch 2 when the preselected number on the counterwheel 1 is reached.
  • the lever 3 When the lever 3 is thus pivoted downwardly, it swings a locking arm 4 in the clockwise direction so that a tooth 4 on its outer end disengages from a resilient or spring-loaded trip member 5 which due to its resilience then moves in the direction of the arrow as shown in FIGURE 1 and thereby actuates a pushbutton switch 6.
  • This switch 6 then energizes a resetting magnet 7 so that its armature 8 is drawn downwardly in the direction of the arrow as shown in FIGURE 2.
  • the outer end of the armature 8 is pivotally connected by a link 9 to the free end of one arm of a bell crank 10 which is pivotable about a stationary axis 1d, while the end of its other arm is disposed between the trip member 5 of the first switch 6 and a similar trip member 11 of a second switch 12 which is connected into the impulse line leading to the counter.
  • the bell crank 10 is pivoted so that its upper arm moves toward the left from the position as shown in FIGURE 2 to that according to FIGURE 3 and thereby disengages from the trip member 11 which due to its spring action disengages from the second switch 12 so that the latter will be actuated and interrupt the impulse line so that no further impulses can act upon the counter until it is reset to its zero position.
  • control means When the switch 12 is actuated and the impulse line is interrupted, suitable control means are actuated to start the resetting movement of the counter and its number wheel 1.
  • control means are conventional adjuncts of the counter wheel reset means 13 shown diagrammatically in all the figures of the drawings.
  • Such means are well known as exemplified in the patents in Class 235444, and as also exemplified by the definition of the latter subclass.
  • the switching circuit according to FIGURE 4 is one in which the impulse transmission is interrupted during the declining or dropping time of the resetting magnet 7.
  • the switching-off or disengagement of the impulse power or transmission is effected with a certain delay which is due to the fact that the contacts are successively switched in or engaged.
  • FIGURE 5 shows a particularly stabable switching arrangement for the automatic renewed preselection with interruption of the impulse transmission during the entire time of renewed preselection, namely by a series connection of the two contacts.
  • each number wheel is connected to a separate notched disk 1 which is adjustable relative thereto so that when the number wheels 1 indicate the preselected number the notches 2 on all of the disks 1 will be in alignment with each other.
  • Lever 3 may then carry a roller 3 which has a sufficient length so as to extend transversely across all of these disks as exemplified by Hazard et 211., 2,538,243. Lever 3 will then not be pivoted until the preselected number on the counter wheels 11 is reached and all of the notches 2 of disks 1 are in alignment with each other in a direction parallel to the common axis of the counter wheels 1'.
  • said control mechanism comprising mechanical means associated with said counter, and switch means adapted to be acted upon 'by said mechanical means to prevent any impulses from acting upon said counter after said indicating means reach said preselected position and during the return movement thereof until said indicating means have been reset to the zero position
  • said indicating means comprising at least one counter wheel
  • said mechanical means comprising a circular disk connected to and rotatable together with said counter Wheel and having a notch in its peripheral surface in a position in a [fixed relation to the preselected position of said counter wheel, a lever pivotable about a fixed axis and having an end portion adapted to engage with said peripheral surface of said disk and to drop into said notch when said counter wheel is turned to said preselected position, a locking member
  • a control mechanism according to claim 1, wherein said lever and said locking mem ber each have an end pivoted on said fixed axis.
  • a control mechanism according to claim 4 wherein said free end portion of said lever comprises roller means, said notc'h releasably receiving said roller means and said roller means being adapted to roll on said peripheral surface, rotation of said counter wheel means causing said roller means to leave said notch and roll on said peripheral surface.
