Dear Mr. Hives:

Re Kingston Oil Rectifier

I am enclosing herewith a short description of the Kingston Oil Rectifier.

You are doubtless familiar with the Skinner oil rectifier, used on Packard, Rickenbacker, and Willys Knight.

This sucks the oil off the piston wall and heats it to drive off water and gasoline but does not filter it.

It requires a special long heavy piston (except on Willys Knight where they use the sleeves) and removes the oil from the piston wall, which we think is wrong as especially at starting we desire to put all possible oil on the piston wall even if it is diluted.

The effect is that one runs on oil which is not diluted but may have become very dirty. Skinner's argument is that the place to stop dirt is before it enters the engine, but he gets his oil full of carbon even if dirt is excluded.

However, Rickenbacker and Willys Knight fit air cleaners and the Packard carburetter is arranged so that an air cleaner is easily fitted.

The Kingston device consists of their vacuum tank (which I described to you yesterday) connected to the induction pipe, and having the upper tank connected to the sump and the lower tank connected back to the crankcase with a removable filter on the outlet.
