DEVICE FOR OPERATING A PIVOTING CHARGING CHUTE

摘要

A driving apparatus for an oscillating spout is presented which includes a control mechanism which directs a control arm to perform the movement required by the spout and a transmission device which acts to transmit the control arm movement and reproduce it as spout movement. The control mechanism consists of a driving rod pivotally connected to an intermediate lever arm and a novel universal joint connecting the lever arm to the control arm. The universal joint enables the spout to be moved in and out of a vertical orientation by prohibiting the components of the control mechanism from becoming axially locked in a 180 DEG angle.
