Abstracts: A rotary worktable is a precision work posining device used in metalworking.In the present invention I provide an improved construction and arrangement of a rotary indexing table for accurately aligning a work-piece with successive working stations so that the exactness of reproducing the machine operations can be relied upon. This involves improved exactness of alignment between working stations and work-pieces and is accomplished by use of a locking and aligning device which locates the center of the work table in an identical position after rotation of the indexing table to successive work positions. The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, its operating advantages and specific objects attained by its use, reference should be had to the accompanying drawings and descriptive matter in which I have illustrated and described a preferred embodiment of the invention.
