From 1877 Boston Directory

In early 1877 Stone & Hazelton, a partnership of J. Frank Stone and Frederic Dana Hazelton, began as a machine shop at 13-15 Bowker Street in Boston. They began manufacturing specialty items patented by Hazelton: a caliper square and a combination tool and rest that fit on an engine-lathe tool-post. They also manufactured lathes, planers, and chucks. They soon moved to 55 Sudbury Street, and by late 1878 they were also manufacturing Chaplin's patent metal planer. The last mention of Stone & Hazelton that we can find is from August 1879: an article in American Machinist shows this firm's "wire chuck" which is, in fact, a collection of collet chucks, and are particularly early examples of such devices.

We have not been able to find any information on J. Frank Stone. As for Hazelton, other then the 1876-77 patents for the above-mentioned specialty items, there is a 1903 patent to Frederick D. Hazelton of Philadelphia, for a table saw, which was manufactured by Hazelton & Donald of Philadelphia which became Hub Machine & Tool Co.

  Stone & Hazelton, Boston, are manufacturing a new style of engine lathe. It has a hollow spindle, with hardened bearings and a draw-spindle to close the chucks which are made of hardened steel. The chucks are made to hold stub's wire or wrought brass from 1/16 to 1/4 inch. It has cast iron bearings with steel spindles. All the parts are heavy in proportion to its size and the lathe is intended to stand a great deal of hard usage.
