Abstract
A locking power clamp assembly for repetitive use to uniformly and securely clamp a closure member over a container opening is disclosed. The clamp assembly includes a clamp arm member having a clamping contact surface. The clamping arm member has an elongated dimension and is capable of generally rotational movement such that when the clamp assembly is opened the clamp arm member will move in a generally perpendicular direction away from the plane of the closure member. The clamp arm member also moves in a radial direction away from the peripheral edge of the closure member. The clamp assembly further includes at least one frame member. The clamp assembly also includes at least two link arm members each being of a different length. The clamp assembly uses a fluid operated piston and cylinder assembly with the piston being connected to one of the link arm members. The clamp assembly is connected to the frame member. The clamp assembly has a rotator member secured to the frame member to support and assist movement of the clamp arm member.
