ABSTRACT:
A resilient finger for use in connection with a poultry plucking apparatus or the like is provided with a head portion capable of being pushed through an opening provided in a movable member associated with the apparatus. The head portion is provided with a resilient base portion which deforms sufficiently so as to allow the head portion to pass through the opening provided in the movable member. After passing through the opening, the resilient base portion returns to its undeformed state and grips the area of the movable member adjacent the opening against a shoulder portion formed on the shank of the resilient finger. A neck having a reduced transversed dimension relative to the shoulder and the base of the head portion is disposed within the opening upon installation. The head may be provided with one or more spiral threads which are engageable by one or more teeth projecting into the opening to facilitate mounting of the finger on the movable member. Alternatively, the head portion can be rounded and provided with a flared lip which deforms during mounting and returns to its underformed state thereafter so as to grip the movable member.
