Abstract: The present invention includes a welding jig having a first support plate and a second support plate rotatably connected to the first support plate. The second support plate has a template-shaped perimeter including arcuately shaped segments shaped to support pipe fittings of different sizes. By selectively positioning a particular segment and securing locking the particular segment in place, a particular pipe fitting such as a particular 90.degree. pipe elbow can be supported with one end resting on the selected particular segment and the other end resting on the first support plate. By this arrangement, particular pipe fitting can be supported in a predetermined and square position relative to a pipe, thus facilitating welding the particular pipe elbow to the pipe. This allows substantially a one-person welding operation.

Abstract: In a workpiece support for use with a laser beam machine tool, in which the workpiece is rotated about an axis tiltable through 90.degree. or more to either side of a vertical condition, the workpiece is held by a chuck driven through a right-angle speed reducer by a servomotor. The chuck, reducer and motor are all supported on a shaft rotatably mounted in bearings on a frame. The shaft is coupled to a disc having angle markings and lockable at discrete rotational positions on the frame. Fine adjustment of the rotational position of the shaft relative to the disc is effected by engagement of an offset protrusion on the end of the shaft by a screw-shifted operating member on the disc. Two such operating members are provided in opposed relationship on opposite sides of the protrusion so that they can be used to lock the shaft and disc securely together.

Abstract: An index table comprising a base, a main plate mounted on the base, a drive wheel mounted for rotation on one side of the main plate about a first axis transverse to the main plate, a work plate on the other side of the main plate rotatably mounted about a second transverse axis spaced from the first transverse axis, and a segment wheel mounted on the one side of said main plate and fixed with relation to the work plate. Circumferentially spaced segment drivers are mounted on the drive wheel and are adapted to engage circumferentially spaced slots on the segment wheel to intermittently drive the segment wheel and in turn the work plate. A yoke plate is mounted on the one side of the main plate for movement radially with respect to the drive wheel and the segment wheel. As the drive wheel rotates, each segment driver engages the yoke plate and moves the yoke plate relative to the segment wheel.
