In centrifugal separator bowls difficulty is experienced in effectively preventing the entrance of moisture into the bowl spindle hearing, which is usually mounted with some elasticity in the separatorframe. One of the main objects of this invention is to so support and enclose the spindlebearing as to make it possible to provide means for effec tively excluding moisture therefrom. The invention comprises a bearing support and means associated therewith to 'preventpenetration of moisture to the spindle bearing. The invention also comprises certain preferred structural features which have been found to provide a satisfactory and efficient spindle hearing as well as to effectuate, in a high degree, the object of preventing moisture penetration.
The drawing, which illustrates such an emv bodiment of the invention, is a vertical sectional view of the bearing, the part of the spindle adjacent thereto, the bearing housing and supporting means and the moisture b, which is preferably, but not necessarily, a
excluding means.
The bowl spindle a turns within a bearing ball bearing, as shown. I The inner ring of the bearing is. confined, to and bottom, between a shoulder '61 on the spindle and a spring plate 6 carried by the spindle. The outer ring of the bearing is confined, top and bottom, be-
tween a shoulder g on a bearing housing f and an elastic ring it held in a groove in said housing. I
Surrounding housing 7 is a fixed frame i. An elastic device, such as a spring is, is placed between frame 71 and housing f, the face of the latter being dished in to afford a seat for the spring. v I
From the top of housing f extends outward aliood on the downwardly extending skirt of which surrounds and is spaced from the upper end of frame 71. From the top of hous ing f extends inward a member having a neck n which surrounds and is spaced from the spindle. Secured to the spindle is a collar 0 whichrhas a skirt that surrounds and is spaced from neck n. i In the described construction the non-rotating bearing housing 7 participates in the the skirt of collar 0.

In order that the bearing housing and the hood carried thereby shall not touchv the frame whenthe bowl is vibrating, there should be a large playbetwcen thehousing and the frame. The enclosure of the upper,

In testimony of which invention, I have hereunto set my hand, at Stockholm, Sweden, on this 15th day of August, 1928'.
