Fig. 1 shows a portion of a base casting 5 which carries the ways for a reciprocating carriage. Fig. 2 is an elevation view perpendicular to the axis along which the carriage 6 travels. The carriage 6 is confined to reciprocating movement by three pairs of fixed rollers that cooperate with rod 7, a fixed way 8 and the sprung way 10. Two pairs of rollers 12 are axially spaced along rod 7, and rollers 15, 16 on a common axis are between the pairs 12 in the direction of carriage motion. The way 8 is rigidly fixed to base casting 5 by a pair of bolts 18. The sprung way 10 provides the biasing to assure that slack or play between carriage rollers and supporting ways is eliminated.
