  • Patent number: 11273537
    Abstract: A swing clamp includes a body with a first end and second end. The body defines a bore through the first end and a cavity at the second end. The bore is in communication with the cavity. A plunger is slidably and rotatably held in the body bore. A lever is pivotally connected to the second end. A link arm pivotally connects between the plunger and the lever. A housing includes an attachment portion and a cylindrical portion. The cylindrical portion includes a bore to enable passage of the plunger. A groove is formed in an inner surface of the bore. The groove guides a pin coupled with the plunger. A clamp finger is secured on the end of the plunger. The clamp finger rotates as the plunger is moved in the bore.

  • Publication number: 20190232464
    Abstract: A piston cylinder has a piston housing including a bore. A piston assembly is movable in the piston cylinder bore. The piston assembly includes a piston disk and a piston rod. A lock piston is movable in the piston cylinder. A lock plate is pivotally secured in the piston housing bore. The lock plate is contacted by the lock piston to move the lock plate into an unlocked position when fluid pressure is applied to the lock piston. A biasing mechanism is in contact with the lock plate. The biasing mechanism moves the lock plate into a locked position when fluid pressure is released or reduced on the lock piston.

  • Patent number: 9906093
    Abstract: A universal mounting housing for a linear actuator has a housing with a wall having an inner surface and an outer surface with at least one bore to enable securement of the housing. The at least one bore has an axial open portion that enables passage of attachment members. The at least one bore has a first and second diameter portion. The first diameter portion extends a length of the open portion. The diameter is of a size necessitating the attachment members to be axially moved into the at least one bore. The second diameter portion is larger than the first diameter portion. The second diameter portion receives a head portion of the attachment member.

  • Patent number: 8500436
    Abstract: A ball lock clamp includes a cylinder housing. A first piston is movable in the cylinder housing in response to a first fluid pressure. A second piston is movable in the first piston. A rod extends from the first piston. A biasing member is positioned in the cylinder housing to provide a biasing force between the first piston and the housing. A plunger is at a terminal end of the rod. The plunger includes at least one ball moving radially in and out of the plunger. A receiver receives the plunger. The receiver retains the plunger in a locked position in the receiver. A mechanism releases the plunger from the receiver. The mechanism includes a member in the rod to move the at least one ball radially in and out of the rod.
