The Rivett No. 3 & 4 Lathes were patented in 1887. The No. 3 had a 7 inch swing and the No. 4 8 inches, with both accepting around 18 inches between centres.  The hardened and ground headstock and tailstock spindles were the same as those used on the (later) "8-inch Precision" lathe and collet sets from 1/64" to 5/8" capacity were available with either a hand-screw or quick-action lever-type closer.
The engineering integrity of the lathe was complimented by a wonderful cosmetic appearance. Although the bed was left as-cast, at least on early models, the headstock and tailstock were machined all over with form cutters, hand scraped then polished to produce that unmistakably-fine, Rivett finish.
