ABSTRACT:
A locator apparatus for supporting a branch pipe fitting adjacent a main pipe for accurately positioning the fitting incident to the welding of the fitting to the pipe. The apparatus includes a track-mounted base located under the pipe, the base being provided with a pivotally mounted horizontal radial arm having a saddle mounted for horizontal movement along the arm. The saddle carries a post having a collar assembly mounted for vertical and rotational movement relative to the post, and the collar assembly provides a support plate to which the branch pipe fitting is mounted. The locator thereby provides the fitting with longitudinal, lateral and vertical linear movement relative to the axis of the main pipe and two different angular movements, about the axis of the post and the axis of the base respectively.
