| 20100139462 | CENTERING BUSHING FOR CENTERING MATERIAL BARS - The invention relates to a centering bushing for centering a material bar which is supplied to a chuck of a lathe. An outer construction and an inner construction arranged therein are rotatably arranged about the longitudinal axis of a material bar. The inner construction is arranged to be rotatable with respect to the outer construction. The outer construction has means to fix the inner construction with respect to the chuck. The outer construction has a centrifugal force device which produces a force corresponding to the rotational speed. The inner construction has a centering device which leads to a centering of the material bar due to a force exerted on the centering device. A force transmission unit is arranged between the outer construction and the inner construction and ensures that the inner construction can rotate, with respect to the outer construction, and transfers the force produced by the centrifugal force device to the centering device. | 06-10-2010 |

PORTABLE LATHE FOR BRAKE DRUM, DISC, OR SHOE | 2 |
| 20090301273 | On-Vehicle Brake Lathe with Indirect Drive - An on-vehicle disk brake lathe has a motor connected to a right-angle gearbox mounted to a body of the lathe, the gearbox in turn driving a spindle shaft through a flexible drive linkage such as a belt or chain. The spindle shaft extends parallel to a gearbox output shaft, and both are normal to an axis of rotation of the motor. The flexible drive linkage can be tensioned by adjustably mounting the gearbox to the lathe body or by use of an adjustably positioned tensioning element. A cover can enclose the flexible drive linkage. The separate gearbox allows the use of durable bearings for the spindle shaft, and allows these bearings to be spaced apart to provide a high degree of stability. The modular structure of the resulting lathe simplifies fabrication and repair, and allows use of a modular body for the lathe. | 12-10-2009 |

| 20120180609 | BEVELLING APPARATUS FOR PIPE RE-FACING MACHINE - In an improvement to a pipe re-facing machine having a rotatable flange plate and a coaxially-mounted collar rotatable with and longitudinally movable relative to the flange plate, a support bracket projects from the flange plate, and a support block is retainingly mounted to and movable relative to the support bracket in an angled radial direction. The support block is adapted to receive a tool holder carrying a cutting element. An actuating mechanism is engageable with the support block such that longitudinal movement of the collar will move the support block relative to the support bracket. The actuating mechanism can thus move the cutting element in an angled direction relative to the axis of a tubular workpiece, thereby enabling machining of a bevelled edge on an annular shoulder of a tubular workpiece non-rotatably mounted to the re-facing machine by longitudinally moving the collar while rotating the flange plate. | 07-19-2012 |
