Abstract:
An adjustable pipe center; the lathe-center may be useful for supporting the end of a rotating workpiece having a hollow along an axis upon which the workpiece is rotating. The adjustable pipe center includes a shaft, a center-head having keyways, a plurality of bearing-fins, and a plurality of power-screws. The center-head is fixed to the shaft and is able to fit within the hollow of the workpiece. The plurality of bearing-fins is able to fit and slide within the keyways, with each having a bearing-surface for contacting the workpiece. The bearing-surface is disposed at an angle to the shaft-axis between zero and ninety degrees. The bearing-fins may be translated, functioning as an inclined plane to displace a workpiece resting against it. When the bearing-fins are collectively translated as desired, it may laterally adjust the position of the workpiece-axis relative to the shaft-axis.

Claim (Index 1):
A lathe-center for a workpiece having a hollow and a workpiece-axis, the lathe-center comprising:\n a shaft having a shaft-axis, the shaft configured to releasably couple with a lathe-spindle; a center-head fixed to the shaft, the center-head configured to fit within the hollow of the workpiece, the center-head including\n a center-base proximal to and concentric with the shaft, the center-base being circular and having a base-diameter, \n a center-end distal to and concentric with the shaft, the center-end being circular and having an end-diameter, the end-diameter being smaller than the base-diameter, \n a conical sidewall extending between the center-base and the center-end, \n a plurality of screw-apertures extending from the center-base to the center-end, and \n a plurality of keyways recessed into the conical sidewall; \n a plurality of bearing-fins disposed within the plurality of keyways, the plurality of bearing-fins being able to slide within the plurality of keyways, each of the plurality of bearing-fins having\n a bearing-surface disposed distal to the center-head configured to engage the hollow of the workpiece, the bearing-surface being neither parallel nor normal to the shaft-axis, \n a retention-flange distal to the bearing-surface structured and arranged to engage the plurality of keyways, the retention-flange being able to prevent the plurality of bearing-fins from moving radially outward from within the plurality of keyways, \n a concavity disposed within the retention-flange, the concavity being semi-circular, and \n a fin-threading integrated into the concavity; and \n \n a plurality of power-screws corresponding to the plurality of bearing-fins disposed within the plurality of screw-apertures, the plurality of power-screws being sized to freely turn within the plurality of screw-apertures, the plurality of power-screws being in engagement with the fin-threading of the plurality of bearing-fins when the plurality of power-screws and the plurality of bearing-fins are assembled within the center-head, such that turning one of the plurality of power-screws causes a corresponding one of the plurality of bearing-fins to slide linearly within the corresponding one of the plurality of keyways, the plurality of power-screws each having a drive-axis, the drive-axis being neither parallel nor normal to the bearing-surface of the plurality of bearing-fins in order to enable the bearing-surface of each of the plurality of bearing-fins to function as a translating inclined plane against the hollow of the workpiece, such that the workpiece-axis of the workpiece is displaced laterally relative to the shaft-axis as any one of the plurality of bearing-fins slides linearly within the corresponding one of the plurality of keyways.
