The edge ofthe board is cut exactly to the form of the core, being indeed a half skeleton reversed. This boardbeing set alongside the bar, and weighted down at the extremities, at a distance of the half diameterof the pipe from the centre, it is evident that, as the core bar revolves and the loam is pushed overupon it, there will ultimately be formed a coating of loam completely enveloping the coat of hay,which shall also possess the figure of the core. 2 T 2 644 FOUNDING

In this manner the core is formed. Figs. 1302 to 1310 illustrate the process. Fig. 1302 is alongitudinal section of a pipe, in which the exterior and interior outlines are represented. Thedotted lines at each end indicate the additions necessary in the pattern as core prints. Fig. 1303represents the core as formed upon the bar, the core being prolonged to be supported in its bearingsformed by the pattern, though it matters not if it should be longer than necessary.
