Specification of Letters Patent.
Patented Apr. 6, 31915.
Application filed. May 23, 1914. Serial No. 840,531.
To all whom it may concern Be it known that I, ALBERT R. J AGKSON, a citizen of the United States of America, and a resident of lVaterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Step-Bearing Heads for Rotary Spindles, of which the following is a specification.
My invention relates to improvements in step-bearing heads for rotary spindles, and the object of my improvement is to provide for the upper annular bearing edge of a step-bearing sleeve used to seat the lower end of the rotary spindle of a cream separator bowl or the like, a covering cap or head of a more resistant material, secured fixedly thereon, and which will resist wear and injuries due to mechanical contacts or impacts of the end of the spindle in fitting the latter into the bearing. This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:
Figure 1 is a side elevation of a stepbearing of the kind described, provided with a resistant wear-head fixed thereon. Fig. 2 is a vertical central axial section of said sleeve and of its said wear-head. Fig. 3 is an upper plan view of the annular wearhead. Fig. 4c is a vertical central axial section of a like sleeve provided with an annular wear-head, in which the latter is somewhat modified in form.
Similar characters of reference denote cor responding parts throughout the several views.
I have shown in the drawings simply one part of the step-bearing of the spindle of a centrifugal cream separator bowl, with its resistant wear-head secured thereon. The sleeve-bearing a is therefore of the usual type, cylindrical in form, of brass or like soft metal, and having its interior hollow threaded as shown, in order to seat therein a step for a spindle, the latter to be introduced into the hollow of the sleeve. The upper annular edge of this sleeve on is formed to slope inwardly as shown in order to afford clearance and ready access to the end of the spindle when introducing it into the hollow c. This sloped upper edge of the softmetal or brass sleeve is often indented and deformed by the impacts of the lower sharpangled end of the spindle when it is being inserted into said hollow, with detriment to the action of the bearing caused by binding and additional friction. It is therefore my purpose to prevent this distortion of the sleeve edge by said causes, by providing a hard resistant steel head or annular wearplate 5 adapted to cover said upper edge fixedly, while having the same contour and inward slope to the hollow of the sleeve. The ring I) is therefore made of an annular troughed shape, the trough downward and adapted to fit over the upper annular edge of the sleeve with its outer depending wall 0 fitted over the sleeve, or in a rabbeted part thereof to keep the outer surfaces in line and flush with each other.
The form shown in Fig. 2 is that of a ring I) which is die-pressed upon the edge of the sleeve under great pressure, which causes a tight and secure fit between the parts. However, for convenience, when desired, thering Z) may be slightly varied in form as shown in Fig. 4, where it has an outer edge inturned at f, the brass sleeve a being cast into a mold in which the part b is seated so as to have the upper edge of the sleeve partially inclosed permanently in the hollow of the other part within its inturned edge 7. Thus fitted together, the cap or head-piece Z) resists wear, preserves its true form, while its inner sloped part d aids in the easy introduction of the spindle.
It is to be understood that other methods may be adopted for specifically attaching the head-piece b to the sleeve a other than those shown, without departing from the principles of my invention.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:
The combination with a cylindrical stepra rs i bearing sleeve, of a wear-head plate secured Signed at Waterloo, Iowa, this 6th day of fixedly upon the upper edge of the sleeve, May, 1914.
I the plate having its outer part directed downwardly and provided with an inwardly- ALBERT JACKSON directed part forming an annular hollow in W1tnesses: v the plate into which the sleeve may be cast W. H. BRUNN,
and thus fixedly secured thereto. GEO. G. KENNEDY.
