Description: |
| This patent was listed on a Bullard Maxi-Mill patent plate.
Abstract:
My invention relates to new and useful improvements in bearings for rotary tables of machine-tools-such, for instance, as boring- mills, vertical lathes, &c. It is the purpose of this invention to provide self-lubricating-bearing for both the table and spindle of machine-tools, whereby the wearing-surfaces will be submerged in oil at all times, whereby the amount of oil contained upon the bearings may be readily determined and likewise replenished during the operation of the machine, and finally to provide a lighter running and longer wearing bearing of this kind than has heretofore been produced.
Claim:
The combination of a self-lubricating table-bearing, comprising a frame having an annular straight inclined bearing therein, an annular oil-pocket upon the inside adjoining the bearing and extended below the surface of the same, radial channels extending from the said annular pocket through the top surface of said straight inclined bearing, and a table having a straight inclined portion to rotate upon the bearing of the frame. |
