  • Automatic lubricator
    Patent number: 4113061
    Abstract: This automatic lubricator is an adaption of sound hydraulic principle, that is the application of lubricant over a sustained time period by pressure in the lubricant. The novel feature is that the design permits readily available pressure from a service gun to be directly responsible for the pressure application, which is then trapped in the device, and made to feed out slowly to the surfaces requiring lubrication. Also, included in the preferred form of the device is a gage to indicate visually the quantity of lubricant within the device.
