Abstract

821,448. Recording - apparatus. HEAT TIMER CORPORATION..July 18, 1956, No. 22290/56. Class 106 (4). An on-off recorder comprises a tape 114 graduated in minutes and hours drawn from a drum at constant speed past a stylus 154 which is held by a spring 159 to record OFF time unless moved by the energization of a solenoid 150 to record ON time and a counter 140 connected to the time drive when the stylus moves to record an ON period. A motor 131 drives gear-wheels 143, 144 secured to rollers 120, 119 which grip the record tape 114 and a motor 131A, connected to a power source through the solenoid 150, drives the counter 140 through gear-wheels 142A, 140A only during an ON period. There may be a plurality of stylus each marking in a different colour or recording may be by a metal point on pressuresensitive paper or it may be magnetic.
