I thought some of you who enjoy mechanisms might enjoy seeing the inside of a Pittsfield oiler.
The pump plunger rotates and is depressed against spring pressure by 7 sheet metal cams. Each cam is adjustable by a square ended screw shaft. As the plunger assembly rotates the little hole in the cone end lines up with one of seven holes in the oiler housing and spits a bit on oil through to a particular brass tube. Each tube goes to a fitting mounted in the oiler top which has a screw you can turn to see how many drops per minute you are getting with the engine running. Each fitting has another tube running to a specific oil point: one to each rod, one to each rod bearing, one to each main bearing and one to the outer transmission bearing. It takes some guessing to get each point lubricated properly with out spewing extra oil all over the undercarriage.
The oiler is filled with oil and a glass sight gage on the side shows the oiler level. I'm not sure if any early Fords used a Pittsfield but all oiler are very special things. The castings and brass parts are true early 1900's craftsmanship.
Sorry, miss loaded pictures.
Thank you Richard!
Drive carefully, and enjoy, W2
