Title: Improvements in devices for sensing perforated tapes for signal transmission
IPC: H04L13/06
Filed: 1957-05-02
Abstract: 841,297. Printing-telegraph transmitters. COMPAGNIE INDUSTRIELLE DES TELEPHONES. May 2, 1957 [May 2, 1956], No. 14074/57. Class 40(3). A perforated-tape transmitter comprises a driving wheel positively operated to step the tape which effects a driving connection to a driven wheel both wheels being rigidly mounted on their shafts, and the driven wheel transmitting its movement through gearing to a wheel freely mounted on the same shaft as the driving wheel, the gearing arrangement being such that the loose wheel normally rotates at the same angular velocity as the driving wheel, whilst the loose wheel stops if the tape breaks or its supply is exhausted. Relative movement between the driving wheel and the loose wheel operates a contact to open the driving circuit of the transmitter. The driving sprocket 1 mounted on the shaft 2 carries a ratchet wheel 3 driven by a resiliently mounted pawl 30 during the release movement of the armature 27 of a magnet 25 operated by a pulse for each code character. The tape 6 passes over and drives a second sprocket wheel 4, identical with the wheel 1 and mounted on a shaft 5 carrying a gear wheel 7 meshing with a toothed wheel 8 driving a gear wheel 10 similar to wheel 7 and loosely mounted on the shaft 2. A radial pin 12 connected to the shaft 2 carries a small roller 11 engaging a recess 13 in a disc member secured to the wheel 10 which is pressed inwardly by a spring 15 in engagement with a disc 14 held against axial movement on the shaft 2. If the tape breaks or becomes exhausted, the wheel 10 is not rotated so that the roller 11 rides out of the recess 13 to press the wheel 10 outwardly to actuate a pin 16 to open the contacts 19 and interrupt the operating circuit of the magnet 25. For each character the wheel 8 rotates a unit counter nl through one step, the tens and hundreds counters n2, n3 being rotated through gears 20, and the arrangement indicating the number of characters which have been transmitted when a fault occurred. The tape may be automatically destroyed after use by a knife member 38 carried on an arm 41 pivoted at 42 and having an adjustable abutment constituted by a screw 40 engaged by an operating projection 37 on the armature 27, the screw carrying a spring 43 associated with a fixed stop 44, and the arrangement being such that the knife is withdrawn from the paper before the armature 27 begins its return stroke. The levers 32 carrying the sensing pins 35 are splayed out at their lower ends to engage their associated contact members. Separate flap members 23, 24 pivoted on the axis X-X<SP>1</SP> are shaped to guide the tape 6 over the sprockets 1, 4 and the ends of the feeler pins 35. The operative winding of the magnet has a shunt circuit including a rectifier and resistor to delay the release of the armature. Specification 774,832 is referred to.
