This double-spindle lathe was a solution to the problem of job shops occasionally needing a big lathe but then having that machine using up floor space most of the time. The lathe is strongly associated with machinery dealer J. J. McCabe. In McCabe's 1919 obituary he was described as having conceived and patented this double spindle lathe. McCabe presented himself as manufacturing this lathe but it was also sold by Cincinnati maker Dietz, Schumacher & Boye, a maker whom McCabe represented in New York. It is likely that Dietz, Schumacher & Boye was manufacturing this double-spindle lathe on behalf of McCabe.
The inventor also had a patent for a trolley wheel, and one for a loom, plus some related to paper making machinery. |
