Description: | A wheel cutting engine. The dividing plate has 24 rows of holes, from an inner ring of 30 through all the usually required numbers up to 96 and then from 100 to 128 in 7 rows, with 365 around the outside. This comprehensive plate provides for everything from normal wheel trains and escapements to a facility for some astronomical work. The crank is geared to the cutter spindle at a ratio of 1;7, and the gantry to the right supports the wheels or stack of wheels to be cut. | Subjects: | Timekeeping | Temporal: | 1790 | Source: | Lincolnshire County Council | Identifier: | http://www.lincstothepast.com/Records/Re... | Go to resource |
