Abstract

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.

Self-Loading Sprung Flat-Way

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. The way 10 includes projections 19, that are received in the shoulders 20 of the pivot projections 21 and a reduced thickness, cantilevered flexure spring portion 24. The flexure portion 24 is also reduced in width at 25 to reduce torsional stiffness and secured at the enlarged terminal end by a bolt 27 to body casting 5.
