Jeff Joslin Vintage Machinery entry for J. J. McCabe Lathe & Machinery Corp.
|
Description: |
This patent covers a "variable swing" lathe where the rear way is much lower than the front way. When only modest capacity is needed, the headstock and tailstock are positioned closer to the front way, which provides better access to the work and a more convenient working height. When more capacity (swing) is needed, the headstock and tailstock are shifted rearward. An article in the April 1918 issue of Machinery describes the lathe, and then the September 1919 issue has a note that the lathe design had been licensed by J. J. McCabe Lathe & Machinery Corporation and was being manufactured for them by the American & British Mfg. Co. of Providence (with a geared head replacing Needham's cone-pulley design). That latter firm owned the old Corliss Engine Works and we believe that is where the lathes were being made. We have seen a couple of surviving examples of this lathe, although Mr. McCabe's own approach to combining two sizes of lathe, his double-spindle lathe (see patent 368,021), is considerably more common. Links to the two Machinery articles are provided in the VintageMachinery.org history page for J. J. McCabe. |
