Model 1020F

History

The Rivett 1020 series lathes were the largest and heaviest ever built by Rivett. The 1020S and 1030S were built from 1949 until 1961, and differed only in bed length.  The 1020S had a maximum distance between centers of 20", while the 1030S increased this distance to 30". The swing over the bed was 12 � inches for both machines. Machine weight was 3,800 and 4,200 pounds respectively. In the last few years of Rivett's existence, as a subsidiary of Leland-Gifford Co., variants of the 1020S and 1030S were produced, called the 1020F and 1030F. These machines had an increased swing of 13 � inches and an electrical, rather than the earlier mechanical, tachometer.

These machines were clearly intended to compete in the same portion of the "toolroom lathe" market as the more common Monarch 10EE, though which came first is not clear. The all-mechanical drive used in the Rivett machines exhibits some advantage over the Ward-Leonard (or electronic equivalent) dc-drive 10EE or even modern variable-speed drives. It incorporates a variable speed drive similar in principal, though much more heavily constructed, to that in the Hardinge HLV-H. It employs a Reeve's style variable diameter pulley system, with speed change accomplished via a small gearmotor. This arrangment potentially preserves a greater portion of the full motor horsepower at low spindle speeds than the electronic drive systems.
