THE  MACHINE-SHOP

machines are provided with special supplies of cooling fluid particularly
suited to the kind of work done in them.

The floods of lubricant supplied are mostly recovered. For the collection
of liquids at the machines, tanks or trays are now fitted. In these the lubri-
cant is drained through a grating, leaving the chips and dirt behind. At

intervals the liquid is drawn off to be treated in centrifugal machines, or in
filters. Fig. 33 is an illustration of the arrangement of oil piping and a
filtering system in the American Tool Works, as laid down by the Richardson-
Phenix Company, of Milwaukee, Wis., U.S.A. The full lines show the supply
pipes for clean oil; the dotted lines, the return drain pipes. The first,
starting from the centrifugal pumps, A, diminish from zj-in. bore to f-in.
bore at their terminations. The drain pipes increase from i-in. to 3-in. bore
where they terminate at the filter B, which is shown in detail in fig. 34.
