Patent number: 6386598Abstract: 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.Type: GrantFiled: May 3, 2000Date of Patent: May 14, 2002Assignee: Delaware Capital Formation, Inc.Inventors: Henry Dykstra, Douglas D. Colby

Patent number: 6105947Abstract: A low profile fixture clamp which provides a clamping force in two perpendicular directions through the motion of a pneumatic cylinder in a single plane. The principle component of the clamping force is a horizontal force in-line with the force generated by the pneumatic air cylinder. An additionally vertical downward clamping force is also generated.Type: GrantFiled: August 21, 1997Date of Patent: August 22, 2000Assignee: Delaware Capital Formation, Inc.Inventor: Henry Dykstra

Patent number: 5967502Abstract: A pneumatically powered clamp that completely encloses the actuating linkage assembly in a fluid-tight, lubricated environment. The clamp includes a pneumatic cylinder longitudinally and removably secured to a plastic body by brackets. The body has a bore to receive a piston rod, and a cavity in communication with the bore. The cavity allows room for the linkage assembly to be pivotally held and cooperate in the body. The bracket substantially seals the body needing only a nylon washer to establish a fluid-tight seal. The linkage means converts the linear motion of the piston rod into rotational motion in the clamp arms which are securely held outside the brackets.Type: GrantFiled: September 3, 1997Date of Patent: October 19, 1999Assignee: Delaware Capital Formation, Inc.Inventor: Henry Dykstra

Patent number: 5961109Abstract: The clamp is a locked over-center toggle clamp having a toggle lever that actuates a clamp arm between clamped and released positions. An amplification lever is secured to a cam pivot for rotation of the cam pivot inside a base. One end of the clamp arm is pivoted to the cam pivot to act as a follower so that rotation of the cam pivot cams the clamp arm to amplify the hold-down force of the toggle clamp.Type: GrantFiled: March 25, 1998Date of Patent: October 5, 1999Assignee: Delaware Capital Formation, Inc.Inventors: Henry Dykstra, Douglas D. Colby

Patent number: 5904349Abstract: A plunger clamp capable of locking in either a retracted or extended position having a rigid body slidably supporting an elongated plunger. A bifurcated lever is pivotally connected inside the body and to a V shaped link arm, the link arm is pivotally connected to the plunger where the link arm translates the angular motion of the lever to drive the plunger between the retracted and extended positions. Essentially the entire linkage assembly is housed in cavities formed by the body during actuation of the lever.Type: GrantFiled: August 5, 1997Date of Patent: May 18, 1999Assignee: Delaware Capital Formation, Inc.Inventor: Henry Dykstra
