Claim 1
Independent Claim
215 words
A built-up slide assembly comprising a bed and a carriage which are relatively reciprocable along an axis, the bed comprising a bed block and a first anD a second rail member attached to said bed block, the said first rail member having three-planar bearing surfaces which are parallel to the said axis and are normal to each other at a pair of dihedral angles located at opposite edges of one of said surfaces, the said second rail member having a planar-bearing surface which is parallel to one of the bearing surfaces on the first rail member, the carriage comprising a carriage block with planar-bearing surfaces in sliding contact with a bearing surface on each of the rail members, a first and a second rail spacer adjacent to each of the rail members, the first of said rail spacers having a thickness slightly greater than that of the first rail member and a bearing surface constituting one of the planar-bearing surfaces of the carriage block in sliding contact with one of the bearing surfaces thereon, a gib carried by the first rail spacer and bearing against the side of the first rail member opposite the first rail spacer, and a rail retainer detachably attached to each of said rail spacers and overhanging the respective rail member.
