Description: |
| A work table of a horizontal boring machine has an overhanging saddle supported by rollers on tracks, the rollers being covered by the saddle and the portions of the roller tracks with which the rollers are in contact being shielded at each side of the saddle by wipers sliding along the upper surface of said tracks and at each side of the tracks by means depending from the saddle closely alongside and to beneath the level of said tracks. The bed a, Fig. 3, of the machine is provided with lateral extensions on which tracks k support the overhanging portions of a saddle f. The latter moves along the bed a and supports a cross-slide h, Fig. 2, on which the work is mounted. Alternatively, a further revolving table i may be carried on the cross-slide h to support the work. Rollers l carried through ball-and-roller bearings n1, n2, Fig. 3, by pins o run on the tracks k. The pins o are carried in brackets p, lugs q of which support the saddle and at the same time protect the side flanges of the tracks k from swarf. Additional filling pieces s secured to the saddle cover part of the exposed sides of the tracks below the saddle, other strips t complete the side protection and engage grooves u in the bed to act also as holding-down members. Wipers r, Fig. 2, protect the top surfaces of the tracks at each side of the saddle." |
