ABSTRACT:
A kiln having a body with an internal chamber accessible via an opening which normally is closed by a closure that is movable. Lift apparatus effects movements of the closure between its closed and opened positions. The lift apparatus includes an arm which overlies the closure and is pivoted to a support independently of the kiln body for rotation about a second axis that is spaced a selected distance from the axis about which the closure rocks. The lift arm is connected to the closure by a pivot coupling which maintains the lift arm and the closure substantially parallel and uniformly spaced apart throughout the movements of the closure. The pivotal connection of the lift arm to the closure enables relative movement of the lift arm and the closure during movements thereof to avoid imposing appreciable stress on either the arm or the closure.
