Definitions

  • This invention pertains to printing telegraph apparatus and more particularly to high speed telegraph tape reperforators.
  • the reperforators in common use at the present time include a punch and die unit which requires very close tolerances in its manufacture, and consequently manufacturing costs are high. It is, therefore, an object of this invention to provide a reperforator wherein greater tolerances are allowable in the punch and die unit, thus reducing the cost of manufacture.
  • a high speed selector mechanism controls the selection of a plurality of punches in accordance with signals received by the selector mechanism.
  • the punches are floatingly mounted in slots in a stationary punch block.
  • the selected punches are caused to perforate a telegraph tape. Thereafter the tape is advanced simultaneously as the punches are withdrawn from the tape, which causes the punches to be moved pivotally until they are withdrawn from the tape.
  • a two cycle selector cam sleeve assembly and a two cycle punch actuating toggle are provided in a modified form of the invention.
  • a simple, high speed reperforator is provided wherein the rotational speed of the selector cam sleeve is effectively reduced.
  • Another object of the invention is to combine a high speed tape perforating mechanism with a high speed selector mechanism.
  • Still another object of the invention is to provide a reperforator having pivoted floating punches whereby the punches may move with the advancing tape.
  • Fig. 1 is a fragmentary isometric view showing the principal features of the preferred embodiment of the invention
  • Fig. 3 is a detail fragmentary isometric view of the selector magnet and armature and the armature locking mechanism
  • Fig. 4 is a detail isometric view of the punches
  • Fig. 5 is a transverse view of a section of tape perforated by punches of the type shown in Fig. 4;
  • Fig. 6 is a fragmentary isometric view of a modified form of the invention showing a two cycle selector and a two cycle punching mechanism;
  • Fig. 7 is a timing diagram of the various operations in the preferred embodiment of the invention.
  • This invention incorporates a high speed selector mechanism of the type disclosed in the patent to W. J. Zenner, No. 2,339,313, issued January 18, 1944.
  • a series of selector levers move to a permutation of marking and spacing positions depending upon the signals received by a selector magnet.
  • cooperating selector interponents also move into marking position.
  • Subsequent rotation of the selector cams causes both the selector levers and selector interponents to be moved to positions to set a corresponding group of punch interponents. Thereafter the selector levers and selector interponents return to normal position, thus providing for overlap.
  • a punch bail engages and moves the punch interponents whereby those punch .interponents which are in marking position engage and in turn actuate corresponding punches to perforate a telegraph tape.
  • the punches are held in position floatingly and pivotally by tension springs. As the punches are being withdrawn from the tape, the tape is advanced, and due to the freedom of the punches to pivot, they are carried along with the tape until withdrawn therefrom, and immediately upon such withdrawal they are snapped back to normal position by their tension springs.
  • Fig. 2 is a front elevational view of the reperabout a shaft l3 which is journalled frictionlessly in a pair of brackets 14 suitably secured to a base (not shown).
  • the shaft 53 is rotated continuously in a clockwise direction by means of a gear 16 which is driven continuously by a suitable source of power (not shown).
  • a selector cam sleeve I7 is mounted rotatably about the shaft is and is integral with a driven member (not shown) of a single revolution selector clutch, the driving drum of which is represented by numeral i8.
  • This clutch whose driving member i8 is secured to the continuously rotating shaft 43 is preferably of the type disclosed in the copending application of A. N. Nilson et al., Serial No. 707,176, filed in the United States Patent Office on November 1, 1946.

  • the selector cam sleeve it carries the usual series of five selector cams El, 22, 23, 25 and 255.

  • the armature 28 is biased by a spring 29 whereby the left end thereof, Figs. 2 and 3, is held in its lower or spacing position when the magnet 27 is tie-energized. Energization of the magnet 21 causes it to pull up the armature 28 to marking position.

  • the cam 62 holds the lever 3i out of engagement with the armature 23 except during the stop and start impulses.
  • each telegraph signal being a marking impulse, it is apparent that the foot 41 will engage the clutch lever at the end of each signal to stop rotation of the transmitting cam sleeve.
  • the start impulse of each telegraph signal being a spacing impulse, it is also apparent that the transmitting cam sleeve will be released for rotation upon the receipt of each start impulse.
  • a pair of armature locking levers 46 and 4'! are mounted pivotally on a shaft c8 and each is biased clockwise by an individual spring 53. Both of the locking levers have a, lug 52 which cooperate with an individual locking cam 59.

  • a comb bar 13 secured suitably to the main frame has slotsin the transverse edgcs thereof which position transversely the selector interponents H.
  • the comb bar 73 fits loosely within the slots '12 of each selector interponent T l allowing eac selector interponent ii a slight degree of pivotal movement.
  • a shaft i l suitably secured to the mainframe limits the clockwise pivotal movement of the selector interponents H and a series of springs 76 secured suitably to the main frame continuously urges the selector interponents H in a clockwise direction.
  • Each selector interponent ii cooperates with a corresponding one of the selector levers El through whereby a, foot '1? on each selector interponent ii remains on top of the correspondt ng selector lever whenever a spacing controls such selector lever and drops behind the selector lever when a marking impulsecontrols it.
  • selector lever $5 and the selector interponent H in the fifth position when the foot .l'l drops behind the selector lever in the manner .described, subsequent rotation of the cam sleeve ll brings an apex or extra high portion 18 of the selector cam 25 against the lug 59 which pivots the selector lever 65 counterclockwise thereby moving the selector interponent ii to the left to set a corresponding punch interponent of a series of punch interponents iii, -82, v83, 84 and 85.

  • a ball crank lever 9I secured pivotally to the main frame -by a bolt 92 has a cam follower 93 which follows a punch interponent release cam 94. The follower 93 is continuously urged against the cam 94 due to the action of a tension spring 96 suitably secured to the main frame.
