发明名称 Motor actuated bell
摘要 In a motor actuated bell a cam member is operatively connected to a motor drive shaft. The cam member acts directly on a leaf spring for moving a hammer attached to the leaf spring generally in parallel relation to the axis of rotation of the cam member to thereby allow the hammer to strike against an associated gong.
