In this casethe work is mostly small and a solid stand with a wheel10 inches in diameter and 3 inches wide was equipped withan adjustable table over the top of the grinding table may be adjusted so that just enough wheel pro- jects to grind lightly the surface of the link blocks orother parts. Babbitt packing rings are also surfaced on amachine of this type. GRINDING IN CYLINDER HEADS The arrangement for grinding in cylinder heads has alsobeen improved, and was illustrated and described in theRailway Mechanical Engineer of November, 1916, page595. \Ve had been using a mechanical crank motion forthis operation for some years but the new arrangement does. Grinding Arrangement for Surfacing Die Blocks the work more quickly and is better because the grindingwheel is driven at a more suitable speed. For the air motorand crankgearing a Westinghouse air pump was substi-tuted on a suitable frame. The back end of the pump ison a fulcrum and oscillates as the cover is moved Ijack andforth.
