J.G.Graves were a Sheffield firm, which, although specialising in mail order at the bottom end of the market, was sufficiently profitable to make their owner the richest man in the city - and its greatest public benfactor.
Although there were several manufacturers in Sheffield who could have rebadged their own shaper to sell under the Graves name, non seem to bear any resemblance to this particular machine.
The ram had a travel of 41/2" and the cross slide 31/4"; the table was 6" x 5", with a rise and fall of 23/4" and a maximum clearance between the cutting tool and the table of 31/4" - it thus fell in size between the much better known and very popular Adept No.1 and 2 models; however, unlike the Adepts, the Graves enjoyed the luxury of an automatic, reversing traverse to the table feed.
Graves also marketed small lathes, the "NV" and the "NV" Portable.
