The pantographprinciple is employed, the tracing wheel wheel is responsible for the extremeUclean and accurate cut made; this re-^suits from the steady advance of thecutting torch into the work. The machine is made in two sizes. TheNo. 1A is applicable to small work anddie cutting, within a cutting area of16 in. sq., a circle of 18 in., or a rect-angular form 12 in. by 40 in. by exten-sion of the tracing table. With this ma-chine a drawing or pattern double thesize of the cut to be made is required, The illustration also shows a recentdevelopment in reducing valves and gascontrol brought out by the Davis-liouronville Co.
