John Levers' lace machine in a Nottingham workshop, rows of thin carriages rocking through the warp on curved combs, finished net running away onto the take-up roller.
What it was used for
John Levers, a frame smith from Sutton-in-Ashfield, built an 18-inch machine in a garret off the Derby Road in Nottingham in 1812 and 1813, so secretly that not even his family saw it. The lace house of Stevenson and Skipwith financed the run: another 18-inch, a 27-, a 36-, a 45- and two 54-inch machines, worked in a shop in St James's Street; at first it was called Stevenson's frame. About 1814 John Farmer worked a 54-inch machine with a second man, five hours each by turns, the machine running twenty hours a day. M. Aubry reported for the 1851 exhibition that English plain cotton net had once been 40 francs the square yard and was 3d. in 1851; Felkin, who reproduces him, corrects that to 4d. as the lowest figure.
What was new
The 1813 machine made net, not pattern; patterning came decades later through the Jacquard, with Samuel Draper's patents of 1834 and 1835 and Hooton Deverill's patent No. 8955 of 1841, which Felkin himself reports only as alleged to be the first really successful application. What Levers added was putting all carriages and bobbins in a single tier instead of two. That forced them to half thickness and demanded finer combs, a stiff frame free of vibration and faultless workmanship throughout; on a Levers machine often thirty carriages and bobbins work safely together edgewise within the space of an inch. It was the execution of an idea which, on Felkin's account, Heathcoat himself had had but not carried out. Whether one Turton had a hand in it Felkin leaves expressly open: it is said, but without any evidence.

Every connection names its kind. “Forerunner” on its own would be a claim.
