| 101 | Polyphase circuit breaker having improved trip crossbar assembly | US773092 | 1977-02-28 | US4128822A | 1978-12-05 | Maurice W. Peterson, Jr. |
| The following specification describes a circuit breaker trip crossbar having diverging radial surfaces receiving a tapered rail therebetween. The rail extends from the bottom edge of the conventional breaker barrier wall recess and forms a small area pivot adjacent the crossbar axis to reduce the torque required to pivot the bar and to render the torque reproducible for calibration purposes.The radial surfaces are economically formed by flat mold surfaces in opposite mold halves to avoid mold flash in the pivot area while enabling one of the mold halves to conventionally form the latch plate securing hole in the crossbar. | ||||||
