  • the sleeve 2 In order to anchor the plural bearing structure in the housing 11, the sleeve 2 is so adjusted that its hole I is aligned with the tensioning screw 18 which then is tightened. The conical tip of screw 18 engages the lower edge of the hole [5, thus depressing the sleeve 2.
  • the flange bolster having a neck extending downwardly into said housing, said neck having a rufi spaced from the bolster proper, a sleeve fixed in said housing against longitudinal displacement, and overlapping the lower portion of the bolster neck,- said sleeve having an inwardly extending flange at its upper end spaced from the ruff, a coil spring mounted on the neck above the ruif, said neck having a recess formed therein and in the 13 of the latter thus is removed from the shoulder 8 of bolster head I, and the pre-stressed spring 1 pulls the partially spherical face of bolster head 1 against the corresponding semispherical seat in the head of housing ll.
  • the resilient flexibility of the connecting sleeve 2 is of importance in that the sleeve cross-section must be capable of being temporarily deformed in order to engage the indentations [6 of sleeve 2 in the holes 10 of step 3 and, thereafter, spring back into its initial shape.

  • Fig. 6 refers diagrammatically toa spindle of conventional design, in which the bolster and step 19 are rigidly interconnected in and through a common sleeve.
