Smith, D R

This patent describes an engine precleaner adapted to be mounted on an engine air intake stack for separating unwanted particulates from particulate entrained gas. It comprises: a housing having a separation chamber, the housing including a generally tubular and vertical side wall surrounding the chamber, the side wall having a first upper end and a second lower end, the side wall further having at least one discharge opening for providing a passageway for gas and particulates from the separation chamber; first end wall means attached to the side wall chamber; second end wall means attached to the side wall at the other end of the separation chamber, the second end wall means having a vane assembly having at least one inlet passage angularly positioned for directing the gas and particulates into the separation chamber in a circular direction whereby the particulates move outwardly by centrifugal force; and an outer tubular sleeve having a first end adapted to be mounted on the air intake stack and a second end extending into the separation chamber to define an outer passage, the outer tube chamber being adapted to carry gas separated from a substantial part of the particulates out of the separation chamber into the air intake stack.
