is externally screw threaded and the lower end
of the bolster 4 is internally threaded to receive

lower end of the step is given the form of a disk I
like head I2 which is notched at intervals, as
best shown in Fig. 5, for engagement with the
vertical blade I3 of a retaining device or keeper.

Having thus described my invention, what I
desire to claim as new is:
1. In a spindle structure, the combination of '
a spindle base, a bolster suspended in a fixed `
position in said base and having lateral bear 40
ings in the baseat both upper and lower portions
thereof serving to hold it in a stationary relation

cluding a part to rest on the spindle rail and also
a tubular imperforate extension projecting below ' 45
said part and» forming an oil well, a spindle blade
mounted in said bolster, a bearing step for the
lower end of said blade screw threaded into the
lower end of the bolster for vertical adjustment
relatively to both the bolster and sai-d base to 50
vary the vertical position of said blade relatively
to the base, the step being supported above the
bottom of said well, the upper portion of said
bolster being provided with a cylindrical 'bear
ing for said blade in which the spindle is moved 65

tween the blade and said cylindrical bearing, and
connections between said bolster and said step for
holding the step in its various positions of ad
justment.

peripheral notches at its lower portion, the upper
portion of said bolster being provided with a
