Description:
First patent to William Foster for a device for applying a lubricant to a plane sole. He discloses soapstone as the material to use to "occasion the plane to run light and easy". His Additional Improvement patent AI68 stretches the idea to more than one recess to hold lubricants such as beeswax and tallow.

In PTAMPIA2, Roger Smith conjectures that Foster or Hazard Knowles had planes of this patent made by The Savage Mill in Savage, Maryland using Knowles' plane 4859X as the basis. An example with a blade marked "DWIGHT'S & FOSTER/WARRANTED/CAST STEEL", and a capiron marked, "PHOENIX WORKS".
