  • Rake movement speed control
    Patent number: 4725366
    Abstract: The present invention relates to a raking apparatus which has at least an upper section and a rake section rotatably coupled to the upper section for rotatable movement from a first position spaced from the bar screen to a second position for removing debris from the bar screen. The rake section moves from the first position to the second position under the influence of a counterweight or other biasing force. A shock absorber placed between the rake section and the upper section controls the forward motion of the rake section to prevent damage to the rake apparatus from uncontrolled forward movement of the rake section from the first position to the second position.
