Oil Can.
Patent for a new and improved oil can. This design utilizes a handle with a hollow tube leading into the oil chamber, so when the removable cap is unscrewed from the handle, air flows into the chamber, which allows the oil to flow. This eliminates the need for a spring-bottom as with other oil cans, for the flow of oil can be stopped by sealing the tube.
