Abstract

698,444. Driving telegraphones. DICTAPHONE CORPORATION. Oct. 25, 1951 [Oct. 6, 1951], No. 24958/51. Class 40 (ii) [Also in Group XXXIX] In a centralized dictation installation (see Group XXXIX), recording apparatus 14 is driven by a motor 124 through an electro-magnetically-operated clutch 172. Correction marks are made on a pad 22 by means of a known device controlled by a solenoid 208. When the recording head 238 reaches a point at a predetermined distance from the end of the record 242, an arm 246 operates a switch 248 to send a faintly audible warning signal to the person recording the message. As the recording head 238 reaches the end of the record 242, the arm 246 operates a second switch 281 to release the clutch 172 and send a louder warning signal.
