Title: Improvements in or relating to line-spacing mechanism for power-operated typewriters
IPC: B41J25/14
Filed: 1923-05-25
Abstract: 220,728. Brougham, F. J., (Addograph Co.). May 25, 1923. Line - spacing mechanism; driving-mechanism. - In typewriters having a carriage supporting a platen roller and a pawl-and-ratchet line - spacing device therefor, a continuouslyrotating shaft, and mechanism for actuating the line-spacing device in any position of the carriage, are mounted on the main framework, and are adapted to be coupled on depressing a key. The platen roller 61 carries a ratchet-wheel 46 cooperating with the tooth 45 of a pawl 44 pivoted to an arm 43 on a rocking frame 40 pivoted on the carriage 57. A shaft 10, driven continuously by a motor 13, carries fast and loose friction-members 14, 15, the member 15 being controlled by a spring lever 17 which engages a lug on a lever 22 operated by a key-lever 24. A pinion 26 on the member 15 engages a sector'27 connected by a link 32 to an arm 33 on a rock-shaft 34. An arm 36 on the rock-shaft is provided with a roller 38. and an ear 42 engaging a flange on the cross bar 39 of the rocking frame 40. The sector 27 has ears 29 for engaging a rubber stop 30 supported by an arm 31 which can be bent for adjustment. On depressing momentarily the key-lever 24, the disc 15 is coupled, the sector 27 is rocked, and the line-spacing pawl is operated. The disc 15 slips if the key-lever is retained in the depressed position. A spring 54 connected to the arm 33 returns to the normal position the parts operated thereby. A stop 56 is provided for the keylever to limit the pressure on the lever 17. The pawl 44 is guided by a hook 49 formed on a plate 62, Fig. 4, secured to the platen frame 51. The tooth 45 of the pawl normally rests on a masking-plate 50 which is pivoted on the plate 62 and can be set in either of two positions to adjust the line-spacing movement. The masking-plate is retained by means of a spring finger 72 having a. projection 73 adapted to engage either of two holes in the plate 62. A stop 75 limits the movements of the masking-plate. When the pawl is operated, the tooth leaves the masking- plate and is drawn into engagement with the ratchet-wheel by a spring 80. The hook 49 is formed with an incline 76 for jamming the tooth at the end of the line-spacing movement. The platen frame 51 may be connected to the carriage 57 by means of parallel links 52 associated with shift mechanism, preferably that described in Specification 208,767, the member 14 being engaged on opposite faces by the friction-member 15, and a friction-member for operating the shift mechanism. The rocking frame 40 and the bottom links 52 are pivoted coaxially, and the links are parallel to a line drawn from the upper edge of the member 50 to the pivot 47 of the pawl 44, these arrangements preventing the line-spacing mechanism from being affected when the platen is shifted. The fast and loose frictionmembers 14, 15 on the shaft 10 consist of a coned fibre disc, and a metal disc having a coned slit flange 15<a>, Fig. 6, respectively, the disc 14 being scraped and cleaned by the edges of the slits.

Filed: 1947-05-29
Abstract: 656,393. Substation equipment. DAPHNE INVESTMENT TRUST. May 29, 1947, No. 14338. Convention date, March 7. [Class 40 (iv)] A subscriber calling a substation provided with record reproducing apparatus obtains access to a recorded message by pronouncing a code of vowel sounds predetermined by the setting of switches at the called substation. When a call is made to such a substation, relays R16, H19, N12 operate, and an electromagnetic coupling VK26 is energized to clutch a motor M14 to drive the tape rollers of a sound reproducing unit 23, which transmits a message to the caller. A cam 25 geared to the rollers of the unit 23 opens its contacts 28, 29, and while these contacts are open the caller may obtain access to a message recorded on the tape of a second unit 34 by pronouncing the required code of two or three vowels pre-selected by the manual setting of the switches 73-75. Filters 122-124 are each arranged to pass a characteristic frequency band of vowels A, O, U respectively, and pronunciation of these vowels effects operation of relays K41, L42, M43. Supposing the required code is A, O, U, correct pronunciation effects sequential operation of the relays K41, L42, L43. K41 completes a circuit over the switch 73 for relay A37 to charge a condenser 44. When the vowel is completed A37 relapses and the condenser 44 discharges through B38 which connects A37 to the switch 74. During the second vowel, L42 brings up A37 which on release causes operation of C39 to connect A37 to the switch 75. The relay M43 re-operates A37 for the duration of the third vowel, and a relay D40 operated in a similar manner to C39, B38 energizes a coupling WK33 in place of VK26. Relay F69 is energized, whereupon the message recorded on the tape of the unit 34 is transmitted to the caller. At the end of the recording a cam 30 disconnects D40 for the unit 23 to complete its message. Cam contacts 28, 29 re-open to de-energize the coupling VK26 and to operate a release relay E36 which returns the apparatus to normal. In the case of incorrect pronunciation of the code a circuit is completed over the appropriate switch 73-75 for release relay E36.
