  • a pivot 118 pivotally mounting a tooth 119 also connected to the disk 113 by a spring 122 and adapted to cooperate with a notch 121 of a sleeve 123 secured to the shaft 66.
  • Another arm 141 of the lever 134 is adapted to cooperate with a projection 142 of a second bail 143 fulcrumed on the shaft 27 urged by a spring 146 to contact the shaft 29.
  • a key depressible Secured to the bail 143 is a key depressible for causing the feeding device to feed the tape in a return direction.
  • Each bail 139, 143 is provided with an arm 147, respectively 148, adapted to cooperate with a pin 149 secured to the trip lever 18.
  • the tape 47 (FIG. 2) to be read is guided between a pair of plates 151 and 152 provided with slots 154 allowing the passage of the pins 46 and the pins 76.
  • the plate 151 is also provided with four holes. 172, only two being shown in FIG. 2, each one slidably mounting a pin 173 having the upper surface knurled.
  • the pins 173 are secured to a plate 174 vertically slidable on four pins 176 secured to the stationary frame of the reader and pushed upwards by four compression springs 177,
  • the plate 174 is provided with two vertical bent portions 180 rotatably mounted on a pair of pins 178 secured to a pair of arms 181 secured to a shaft 184 rotatab e on the stationary machine frame.
  • Secured to the shaft 184 is also a third arm 186 normally urged by the springs 177 to contact a cam 187 of the main shaft 5.
  • the feeding device operates as follows.
  • the feeding device is predisposed for advancing the punched tape rightwards.
  • the pins 76 of the feeding member 74 engage the feed holes of the tape 47, while the pins 46 enter the possible code combination holes punched on the tape 47.
  • the pins 46 not entering a hole are displaced downwards by the tape 47 against the urge of the springs 48.
  • the levers 49 are thus selectively positioned to face the projections 52 to the arm 54, or the projection 53 to the arm 56, of the corresponding levers 57.
  • the trip lever 18 is rocked counterclockwise and is latched in rocked position by the latch 32. Then the lever 18 on the one hand causes the transmitting shaft 17 to be rotated clockwise on revolution, on the other hand it releases the tooth 8 which immediately engages the notch 11. Therefore as the shaft 17 starts rotating counterclockwise, through the wheels 16 and 14 and the clutch 12, 8 it also rotates the shaft 5 clockwise. Moreover, through the wheels 67 and 68, theshaft 66 is rotated counterclockwise whereby the eccentrics 89 and 92 are rotated in opposite directions.
  • the pins 46 of the sensing members 42 which encounter a code hole on the tape 47 are moved along a path similar to the one of the pins 76.
  • the pins 46 which do not encounter a hole are arrested by the tape 47 and during the causing operation instead of covering the path FABD (FIG. 3) successively cover the straight segments FH, HK, KD.
  • the code combination set up on the levers 49 (FIG. 2) is transferred to the code bars 72 while the pins 46 and 76 are moved along the segment AB (FIG. 3). Then the cams 64 rock the lever 62 counterclockwise till the arms 54, 56 of the levers 57 engage the projections 52, 53 of the levers 49. Thus the levers 57 are selectively rocked in accordance with the code combination set up on the levers 49, whereby the code bars 7 are accordingly positioned to transmit the relevant code combination over the telegraph line in a manner known per se.
  • the cam 187 causes the springs 177 to displace the plate 174 upwards, whereby the tape 47 is pinched between the knurled surfaces of the pins 173 and the plate 192, thus preventing the tape 47 from returning or being unduly displaced.
  • the shafts 17 and 5 are cyclically rotated as long as the lever 18 (FIG. 1) is held rocked by the latch 32.
  • the lever 37 through the lug 36 rocks the latch 32 counterclockwise.
  • the latch 32 releases the lever 18 which at the end of the reading cycle on the one hand causes the shaft 17 to be arrested, on the other hand disengages the tooth 8 from the notch 11 thus stopping the eccentrics 89 and 92, whereby the reader is stopped.
  • the bail 143 Upon depressing the key 144, the bail 143 on the one hand through the arm 147 rocks the lever 18 at the depression of the key 86, on the other hand through the projection 142 rocks the lever 134 clockwise. Now the cam surface 133 rocks the bail 128 clockwise, whereby the tooth 119 is rocked counterclockwise and engages the notch 121 of the sleeve 123.
  • the disk 113 is rotated one revolution counterclockwise.
  • the pins 110 of the disk 113 engage one of the toothed portions -109 of the geneva wheel 108, which is thus rotated 90 degrees clockwise together with the shaft 104, where-by the projections 103 are positioned horizontally.
  • the shaft 104 through the wheels 106 and 107 rotates the shaft 98 90 degrees counterclockwise, thus positioning the projections 97 vertically.
  • the lever 119 is latched again by the lug 128.
  • the link 87 is guided by the projections 103 and is thus caused to displace the bar 77, while the link 86 follows the path of the pivot 83 and merely contributes to vertically displace the bar 74.
  • the bar 77, the frame 44, the feeding member 74 and the slides 42 follow the path shown in FIG. 3 by a broken line 189. More particularly, at the beginning of the first cycle of the shaft 66 the pins 76 should be displaced from the point A to the point B.
  • the projections 103 immediately engage the link 87, whereby the pins 76 are moved in effect from the point A to the point B, whereby the tape 47 is returned one step. Subsequently the pins 76 are moved along the arc B, C, E, GA in a manner similar to that previously described.
  • the feeding member 74 is secured to the frame 44 of the sensing members 42 and is operated by a pair of eccentrics 89, 92, the eccentric 89 being adapted to positively reciprocate the feeding member 74 in the feeding direction, both eccentrics 89, 92 being adapted to jointly control the feeding member 74 to be reciprocated in a direction perpendicular to said feeding direction.
