The drafting machine, introduced about 1930, allows a straightedge to be moved while maintaining any desired angle between it and the edge of the drawing board.
A drawing that would in the past have taken an architect hours or even days to finish could be completed in a minute or two by a computer-driven drafting machine.

Continuous-path NC systems are commonly used on machines that perform contouring operations, such as milling machines, lathes, flame-cutting machines, and drafting machines.
Other machines using numerical control include component-insertion machines used in electronics assembly, drafting machines that prepare engineering drawings, coordinate measuring machines that perform accurate inspections of parts, and flame cutting machines and similar devices.
He makes his own block ice, daily, by freezing water in a loaf pan and then carving it into oversize chunks for use in cocktails, and he sometimes travels to Williamsburg, in Brooklyn, to harvest colder, more esteemed cubes of ice from a friend who owns a Kold-Draft ice machine.

Adding to the theatricality was the arrival of Kold-Draft ice machines, which become de rigueur at the top cocktail caves.
