Patent number: 8459626Abstract: A clamp having a lock is provided. In another aspect, a fail safe lock maintains the position of a clamping member when fluid pressure or other actuating power is undesirably reduced. Another aspect employs teeth on a locking structure which engage matching teeth on a shaft where engagement of the teeth prevent unclamping of a workpiece. In still another aspect, a manual override member disengages a lock in order to unclamp a workpiece.Type: GrantFiled: May 28, 2010Date of Patent: June 11, 2013Assignee: BTM CorporationInventors: Edwin G.

Patent number: 7685925Abstract: An intensifier is operable to supply force and includes a housing defining a cavity. A ram is slidably positioned within the cavity and partially extends from the housing. The ram is moveable between retracted and extended positions along a longitudinal axis. First and second links are rotatably coupled to one another about an axis of rotation and are selectively moveable between retracted positions where the axis of rotation is not axially aligned with the ram and partially extended positions where the axis of rotation is axially aligned with the ram. The intensifier includes a plurality of power pistons axially aligned with each other and the ram. The power pistons are selectively operable to provide an output force to the ram when the first and second links are in the partially extended positions.Type: GrantFiled: August 15, 2007Date of Patent: March 30, 2010Assignee: BTM CorporationInventors: Edwin G. Sawdon, Steven J. Sprotberry, Brian D. Petit

Patent number: 7370856Abstract: A clamp includes a body, a lead pin moveable relative to the body and an actuator supported by the body. The actuator is axially moveable between an extended position and a retracted position. The actuator includes a camshaft drivingly coupled to the lead pin. Axial movement of the camshaft causes the lead pin to rotate between a first positioned aligned with a first longitudinal axis and a second position aligned with a second longitudinal axis laterally offset from the first longitudinal axis.Type: GrantFiled: October 4, 2005Date of Patent: May 13, 2008Assignee: BTM CorporationInventors: Edwin G.

Patent number: 7194859Abstract: An intensifier is operable to supply force and includes a housing defining a cavity. A ram is slidably positioned within the cavity and partially extends from the housing. The intensifier also includes a force transfer rod and a plurality of power pistons. The ram is moveable between retracted and extended positions along a longitudinal axis. The force transfer rod is selectively moveable between a retracted position where the force transfer rod is not axially aligned with the ram and an advanced position where the force transfer rod is axially aligned with the ram. The plurality of power pistons are axially aligned with each other and the ram. The power pistons are selectively operable to provide an output force to the ram when the force transfer rod is in the advanced position.Type: GrantFiled: October 18, 2005Date of Patent: March 27, 2007Assignee: BTM CorporationInventors: Edwin G.

Patent number: 7029000Abstract: A clamp and method for locating a clamping workpiece in predetermined location are disclosed. The clamp includes a clamp body, a driving member, a workpiece-locating pin and a clamping member. The driving member is moveable in a first linear direction at least partially inside the clamp body. The workpiece-locating pin is moveable in a second direction substantially perpendicular to the first direction and at least partially externally projects from the body. The clamping member is moveable relative to the workpiece-locating pin in the first direction when moving between a retracted position and a clamping position.Type: GrantFiled: September 7, 2004Date of Patent: April 18, 2006Assignee: BTM CorporationInventors: Brian D.
