Abstract:
An oil dipstick wiper comprising:(A) an oil dipstick; and(B) a hollow housing which is selectively-releasably-engaged with an oil dipstick guide tube which is secured to an engine, said hollow housing having a central longitudinal bore therethrough, said central longitudinal bore including an upper end and a lower end, said hollow housing including:(i) an upper rectangular slotted plate which is disposed at said upper end of said central longitudinal bore for guiding said oil dipstick in longitudinal sliding movement, while substantially-simultaneously preventing rotation of said oil dipstick;(ii) resilient wiper means projecting into said central longitudinal bore, so as to intrude into a major extent of said central longitudinal bore,(iii) oil catching means which is associated with said resilient wiper means and which is disposed vertically therebelow and which intrudes into said longitudinal bore for catching oil which is wiped off of oil dipstick by said resilient wiper means, and(iv) spring means which are disposed within said longitudinal bore at said lower end thereof to provide said selectively-releasable engagement with said oil dipstick guide tube;wherein said an oil dipstick is selectively-slidably and non-rotationally-disposed within said central longitudinal bore of said hollow housing;whereby:(a) said hollow housing and said oil dipstick are selectively-longitudinally-movable as a unit, and said oil dipstick is alternatively longitudinally, slidingly, and non-rotationallv-selectively-movable by itself with respect to said hollow housing; and(b) when said oil dipstick is longitudinally-moved by itself out of said hollow housing, oil is wiped off of said oil dipstick by wiping contact of said oil dipstick with the resilient wiper means, and, when said oil dipstick is retarned to said hollow housing and is inserted into an oil sump of the engine and when a unit comprising said hollow housing and said oil dipstick is removed from engagement with said oil dipstick guide tube, oil remains on said oil dipstick so that the level of oil in said oil sump can be determined.
