From an description of Huntington Machine Works (which is quoted in full in the Information Sources section of the history page). The part relevant to this image is as follows.
"...a lathe for turning irregular forms, such as spokes, whiffletrees, cart-rungs, handles, &c, &c; and which might perhaps, for short, be called a spoke turning lathe. The arrangement of parts is generally as follows: It consists of an upright frame, in which is contained an oscillating frame, with the pattern of the article to be turned, together with the material to be fashioned. This oscillates by means of rests, so arranged as to give a certain motion against the cutter-head containing the cutters, which makes about 2,500 revolutions per minute. The material revolving with the pattern, and its oscillations against the cutters being governed by the former, it is clear that, when finished, the work will be fashioned exactly to the shape of the pattern." |
