Pendulum device for clocks

Abstract

A pendulum rod is mounted so as to be able to swing within a desired or a normal swing angle. The means mounting the pendulum rod include means for restricting movement of the pendulum rod along the swinging axis relative to the support body when the pendulum rod is within this desired swinging angle to prevent the detachment thereof and for enabling free movement of the pendulum rod along the swinging axis when the pendulum exceeds the desired swinging angle to permit detachment thereof. The mounting means also include means for restricting upward movement of the pendulum along longitudinal axis and relative to the support body to prevent detachment thereof. These desired functions are carried out by one of the swinging center body and support being provided with a pair of v-shaped projections positioned at a desired interval and the other of the center body and the support portion have a pair of v-shaped grooves which engage the projections and the restricting portion which is loosely fitted between the projections and restricts the longitudinal movement of the swinging body.
