Definitions

  • the present invention has for its object the simplification of the punching mechanism to the general end that punching operations may be efi'ected very rapidly and with the minimum of effort upon the part of the operator. Provision is made for both positively actuating the punches and for positively withdrawing the punches after the punching operation.
  • the use of individual springs is obviated.
  • a further object of the present invention resides in the provision of a simple means for selecting and actuating a punch or punches. the actuation of the selected punch being ettected by a constantly running main actuator. Means are provided for positively restoring the punch after it has been actuated by means of the same main actuator.
  • a further object of thepresent invention resides in the provision of a simple construction for efiecting punch operations under the power of a constantly running main actuator and for providing for a single punch operation and the preventing of repeat operations in the event that the selector device is held in displaced position.
  • a further object of the present invention resides in the provision of a punch selecting and actuating mechanism which is simple and inexpensive to manufacture and which will be adapted to require the minimum of efiort to operate the same.
  • Fig. 2 is a top plan view of the apparatus shown in Fig. 1.
  • Fig. 3 represents a sectional view taken on just prior to the commencement of the restoring operation.
  • Fig. 6 shows the position of the parts in normal position after punching operation but withthe key maintained depressed.
  • Figs. 7 and 8 are views of a modification of the invention showing one punch and corresponding restoring mechanism.
  • 10 designates the punches which are suitably guided and cooperate with. the stripper and die 11 and 12.
  • the card to be punched is inserted in the die in any de sired manner and may be fed after each punching operation in any manner now well known in the art.
  • Cooperating with each of the punches is a bell crank member 13 pivoted upon a shaft 44 and preferably having a nose portion engaging and fitting in a slot disposed in theside of the punch stem.
  • the individual bell cranks 13 are each connected to secondary actuators 14;.
  • the configuration of the secondary actuator is best shown in Fig. 4.
  • Each is provided with a shouldered portion 15 for cooperation with a restoring bail 16.
  • a Keg board The keyboard and key selected and actuated means for selecting the punches for operation comprise a plurality of selector or key Fig. 1 illustrates a side part sectional view levers 24 pivoted upon a shaft 25. Each key lever or selector carries the usual key button 26 which may be numbered or lettered as desired.
  • One pawl or dog 18 is pivotally secured to each kev member and resiliently held against a suitable stop or lug 27 by means of a spring 28.
  • the key members may be drawn to upper position in any suitable manner as bysprings 29.
  • the main actuator preferably is of the form shown in F i s. 1 and 2. It comprises a fluted or toothed shaft 30 suitably gournaled in the machine frame and arrange to be constantly driven by any suitable source of power such as the electrlc motor 31.
  • the individual teeth on the main actuator are designated 32.
  • the means for restoring the punches preferably comprises a restoring member 33 (Fig. 5) preferably pivotally supported at one end by a link 34 and having a. shouldered portion 35 cooperatively disposed with respect to the restorm bail 16.
  • the restoring member is provide with a hooked end 36 adapted for cooperation with the teeth 32 of the main actuator. It is also preferably provided with camming surfaces 38 and 39 adapted for cooperation with suitable means such as studs 40 and 41 fixed to the frame of the machine.
  • a suitable spring 42 is also connected to the restoring member.
  • the operator depresses the desired key (for example, the key lettered '26 in Fig. 1).
  • the key lever 24 is then depressed pressing down upon dog 18.
  • a notch 43 in the dog 18 is in engagement with the lug 17 Consequently, the lowering of dog 18 depresses or displaces the corresponding sec-.
  • Part 14 finally reaches such a position that part or cam surface 20 thereof contacts with and rides up cam 21 but before the parts have reached the position the lug 17 will have been withdrawn clear of and out of cooperation with the notch 43 in dog 18.
  • the purpose of the engaging and camming action at 20-21 is to provide means for positively withdrawing the secondary actuator from engagement and cooperation with the main actuator after a punching operation is completed. It will be understood that this disengagement will take place irrespective of any maintained depression or actuation of the selector means such as key 26 inasmuch as at this time in the cycle parts 17 and 18 are out of cooperation.
  • the parts are so proportioned that the restoring member does not engage the tooth of the main actuator at the same time as the secondary actuator does. It lags by substantially one half tooth cycle, as clearly shown in Fig. 4, which shows tooth 19 just before it is disengaged from 32 and tooth 36 just before engagement. fter engagement has taken place, the rotation of the main actuator thrusts the restoring member to the left, restoring bail 16 from the csition shown in Fig. 5 to that of Fig. 6 and thus positively restores the punch or punches which have been displaced. It will be understood that as the restoring member is moved to effect restoration of the punches it is positively disengaged from the main actuator by means of the cam devices 38394041. When the restoring operation is complete, the tip 36 is com letely disengaged and the parts are ready or a subsequent and possibly different punch selection and punching operation.
  • Fig. 6 further illustrates the means for preventing repeat punching operations in the event that the punch selector means, such as the key, is held down.
  • the secondary actuator With 24 depressed the secondary actuator upon its return movement will move from the position of Fig. 4 to that of Fig. 6 and the lug 17 will engage the side of the dog 18 and displace it against the tension of spring 28 to the position shown in Fig. 6. It is now. necessary to again elevate the selector lever 24 to permit re-engagement of notch 43 with lug 17 before the secondary actuator can again be brought into cooperation with the main actuator.
  • the device is adapted for punching two or more holes simultaneously. It is only necessary that the selector members 24 be displaced simultaneously.
  • the device also is adapted for extremely rapid operation as the selectors may be operated or selected in rapid succession even before the precedingly operated or selected selector has been restored to home position. It is only necessary to operate the selectors at a sutlicient time interval to allow the respective different secondary actuations to engage different or successive teeth on the main actuator.
  • the speed of operation of the main actuator may be varied as desired or in accordance with the skill of the operator or speed of operation of the selectors.
  • Fig. 7 illustrates a different embodiment of the invention in which a single punch 10 only is illustrated and in which the restoring member 33 is directly connected to bell crank 13 instead of acting thereon through the restoring bail.
  • Member 24a carries a lug 60 which when depressed by lowering of the left end of 24a engages a dog 18a pivoted upon the secondary actuator 14 and draws it down to engaging position.
  • Spring 29a serves the dual function of drawing down on 33'and of throwing up upon part 24a. Inother respects the action is the same as that of the device previously described.
  • a punching apparatus comprising in combination, a main actuator, a plurality of punches, a plurality of secondary actuators therefor, each selectively engageable with the said main actuator, restoring means for said secondary actuators and punches also operable by said main actuator, and means automaticallycontrolled by the action of the secondary actuators for bringing the restoring means into operative connection with said main actuator.
