No. 7 Engine Lathe

Lathes, as ordinarily built, have the carriage ways located under the cutting tools, and when in operation, the chips and dust fall directly upon them. The oils on the ways retain the dust and grit, and as the carriage passes back and forth, a process of grinding is commenced that very soon hollows down and destroys them. The gibs that hold the carriage to its ways become loose at points where most used, and if tightened at these worn points, they will not allow the carriage to move on the less worn parts of the ways.

To overcome this and make it possible to use the lathe, spring gibs have been applied to force the carriage to conform to the uneven surfaces; while these will steady the carriage, they will not keep the tool from jimmering, or cause the lathe to do good work. To correct these faults in the engine lathe, to increase its wearing surfaces, and to better proportion it for strength is the object of the improvements described below.

This lathe, in general appearance, differs but little from the ordinary engine lathe. It has, however, some important improvements that have been in use several years, giving results decidedly in their favor.

Prices quoted upon application. Six foot bed lathe weighs 1,000 pounds, Eight foot bed lathe weighs 1200 pounds.
