Engine oil dip stick indicator wiper

Abstract From the Canadian patent

A wiper system for use in removing the oil film deposited on an automobile engine dip stick. The small wiper system comprises a rigid frame adapted to be anchored to the engine compartment and having a vertical channel made thicknesswisely thereof. Two pairs of vertically spaced semi-, flexible flaps are edgewisely mounted at their inner ends to the opposite side walls of the vertical channel and are pivotable as, if swingable doors. The flaps of each pair of flaps are slightly vertically offset. When a dip stick engages the channel of the wiper system, the free end sections of the flaps will wipe the surface of the dip stick, in order to remove the oil film deposited thereon.
