Description: |
| Abstract:
This invention relates to improvements in lubricators or oil-cups used for supplying lubricant automatically to moving and operating parts in machinery. It relates more particularly to such oilers in which the operation is by gravity and where the discharge may be regulated as to quantity as well as entirely interrupted when desired.
Claim:
In a lubricator, the combination of an oil-reservoir formed of a cylindrical shell, an upper and a lower head, the latter having a socket on its inner side provided with an outlet-port in its bottom and a drip-nozzle below, a hollow tie-post provided with a shoulder which engages the upper head and by being tapped into the socket of the lower head, holds the heads to each other and in position on the shell to form the oil-reservoir, a spring-actuated valve-stem contained in this tie-post, having a valve at its lower end, a screw-plug to open at both ends to adjust the position of this valve-stem, a cap seated on the upper end of this plug closing the same thereat and engaging it for purposes of rotation to adjust the same, a manipulating handle pivotally attached to the upper end of the valve-stem which latter extends through this plug and cap, protruding beyond this latter and a spring contained under the cap to hold the same normally against the handle in all adjusted positions. |
