Definitions

  • My invention provides an improved arrangement of the guides and the mechanism actuating the slides, whereby an exceptional length of the bearingsurfaces is obtained, and the invention consists in a combination wherein the rack is fixed to the bed above the main guide of the slide rest, covering the same, and the lead screw is arranged directly below the said main guide, and is thus protected by the same.
  • Figure 1 is a partial cross section taken through the bed and slide rest at the gap.
  • Figure 2 is a cross-section taken through the bed and rack.
  • Figure 3 is a front view showing the gap.
  • Figure l is a front view of the slide rest.
  • Figure 5 is a cross-section of part of the bed and the guard at the gap.
  • Figure 6 is a front view of part of the carriage with the apron or front plate of the gear box on the slide removed.
  • Figure 7 is a planview of the carriage.
  • FIG. 1 designates the bed, having at the top guides 2 and 3 for the sliding carriage.
  • the guides 41- and 5 for the slide 6 (I being the main guide) are at the sides of the bed, lower down.
  • To prevent bending of the saddle of the slide 6, the same has an additional guide surface resting on the guide 2.
  • To prevent the rising and lat eral deviation of the slide under stress during the working the same is provided with flanges 8, 9 which engage under the part 5 and 11 of the bed, and can be tightened up by means of screws, to compensate for wear and regulate the pressure of the slide on the bed.
  • the rack 12 is screwed to the bed above the guide 4, at one side of the bed and ex posed at the top, but the rack is made wide so that it protects the guide from shavings.
  • the rack may be made in two parts.
  • the lead screw 13 and the control shaft 14 are below the bed, protected by the laterally projecting guide member 11 already referred to.
  • the pinion 15 is mounted on the slide between the guide 1 and the channel provided for the rack.
  • a guard 16 is provided at this part, and conforms to the shape of the slide, so that the slide can be moved uninterruptedly to the head stock.
  • Figures 1 and 1, 17 designates the contact surface between the body of the slide and the bottom of the gear box, these parts having at the sides lugs 18, which are screwed to each other. The position of the joint at this part obviates torque in the cutting screws, as the joint is close to the nut 19 and there is practically no leverage.
