ABSTRACT:
A drive means 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 universal joint connecting the lever arm to the control arm. A novel movable torque means is associated with the universal joint and enables the spout to be moved in and out of a vertical orientation by overcoming the tendency of the components of the control mechanism to become axially locked in a 180.degree. angle. The movable torque means accomplishes this result by reducing the angle between the intermediate lever and control arm when that angle reaches 180.degree..
