Description: |
| Abstract:
This invention relates to those lubricators or oilers which have glass founts, globes, or reservoirs that contain the lubricating-fluid and the first part of my improvement consists in imparting a special shape to such reservoirs. This special shape includes a globular or spheroidal fount, a neck which is preferably cylindrical and a contracted waist, the latter being located at the junction of said fount and neck. The fount has an opening at top which is covered by a head or cap of the axial tube that contains the valve and its seat, said tube being screwed into a lower section or cage that fits within the cylindrical portion or sight-chamber of said fount, the upper end of said cage having a bearing that retains a gasket or packing-ring within the contracted waist. By this arrangement, the axial tube serves to clamp all the members of the device securely in place and prevents leakage at the various joints of the same.
Claim:
As a new article of manufacture, a transparent oil-reservoir consisting of a vessel A, open at top and bottom, and joined by a contraction or annular bearing C to the sight-chamber D said members A, C, and D being composed of a single piece of material, and the contraction C being of less diameter than said vessel A and sight-chamber D. |
