Patent number: 8474124Abstract: A tooling system comprises a plurality of elements arranged in an array, the elements of the array being movable between a closed position in which the elements contact one another and are secured in position, and an open position in which the elements of the array are spaced apart and are capable of vertical movement relative to one another, characterized in that the tooling system further comprises means for retaining the elements of the array in a plurality of different relative vertical alignments. A method of operating the tooling system is also described, which method of operating includes at least the steps of moving the elements of the array into a first vertical alignment, machining the free ends of the elements according to a predetermined pattern and moving the elements of the array into a second vertical alignment in which the machined ends of the elements produce a desired surface contour.Type: GrantFiled: June 29, 2005Date of Patent: July 2, 2013Assignee: Surface Generation, Ltd.Inventor: Ben John Halford

Patent number: 8469344Abstract: A tooling system (1) having a number of elements (2) arranged in an array, which elements define a contoured surface, or a section of a contoured surface. The tooling system also including means (7) for mounting an element to a support rail (5) which extends across the array, which means allows adjustment of the height of the element with respect to other elements of the array, and extends through the support rail into a space defined below the support rail. A supporting element (6) formed from a suitable resistant material and including accommodation means (8) for the means for mounting, is located in the space below the support rail and is sized so that it substantially vertically fills the space between the support rail and a base on which the tooling system is located.Type: GrantFiled: June 25, 2007Date of Patent: June 25, 2013Assignee: Surface Generation, Ltd.Inventor: Ben John Halford

Patent number: 7726167Abstract: A tooling system comprises a plurality of elements (24) arranged in an array, each element being supported on a cross rail (22) and being moveable relative to the other elements in the array. Each element terminates in a threaded support post (25) extending from a first end of the element, and is associated with a corresponding internally threaded aperture in the cross rail upon which the element is supported. The tooling system further comprises an adjusting component in the form of a fork (46) which is driveable in rotation and engageable with an element of the array to drive the element in rotation, upon rotation of the fork.Type: GrantFiled: December 23, 2004Date of Patent: June 1, 2010Assignee: Surface Generation, LtdInventor: Ben John Halford
