Claim 4
Dependent Claim 108 words
An oil dipstick cleaning device, comprising a support having an elongated slot therein, a holder having a flange engaging said slot said holder having a cleaning pad retaining portion, a cleaning pad being disposed in said portion and having a central slit therein lying parallel to said slot, and said support having an opening, whereby an oil dipstick to be cleaned extends through said opening with said holder being shifted along said slot so as to move said pad away from the dipstick, said holder then being moved along said slot until said pad surrounds the dipstick via said slit, the dipstick then being extracted from said pad.
Claim 5
Dependent Claim 151 words
An oil dipstick cleaning device, comprising a support having a pair of axial openings, a pad of cleaning material disposed within only one of said openings and having a passageway therein, in combination with an oil dipstick having a pair of elongated elements respectively inserted through said passageway and through the other of said openings, said elements extending into a quantity of oil for measuring the level thereof, whereby upon extraction of the dipstick one of said elements extending through said passageway is wiped clean by said pad and the other of said elements being used to read the level of the oil, and whereby re-insertion of the dipstick with said one element extends through said other opening and said other element extends through said passageway permits said other element to be wiped clean and said one element to be used for reading the oil level upon again extracting the dipstick.
Claim 6
Dependent Claim 151 words
An oil dipstick cleaning device, comprising a support having a pair of axial openings, a pad of cleaning material disposed within only one of said openings and having a passageway therein, in combination with an oil dipstick having a pair of elongated elements respectively inserted through said passageway and through the other of said openings, said elements extending into a quantity of oil for measuring the level thereof, whereby upon extraction of the dipstick one of said elements extending through said passageway is wiped clean by said pad and the other of said elements being used to read the level of the oil, and whereby re-insertion of the dipstick with said one element extends through said other opening and said other element extends through said passageway permits said other element to be wiped clean and said one element to be used for reading the oil level upon again extracting the dipstick.
Claim 7
Dependent Claim 79 words
An oil dipstick cleaning device, comprising a support having a pair of axial U-shaped passageways, a pad of cleaning material disposed in only one of said passageways, in combination with an oil dipstick having a U-shaped cross-section, said dipstick when extending through said one passageway being wiped clean along one side thereof by said pad, and said dipstick when extending through the other of said passageways being available for reading the level of the oil into which it extends.
Claim 8
Dependent Claim 79 words
An oil dipstick cleaning device, comprising a support having a pair of axial U-shaped passageways, a pad of cleaning material disposed in only one of said passageways, in combination with an oil dipstick having a U-shaped cross-section, said dipstick when extending through said one passageway being wiped clean along one side thereof by said pad, and said dipstick when extending through the other of said passageways being available for reading the level of the oil into which it extends.
Claim 9
Dependent Claim 66 words
An oil dipstick cleaning device, comprising an elongated portable jacket having a cleaning pad disposed therein near one end thereof, an oil dipstick extending through said jacket and through an opening provided in said pad, whereby said dipstick may be wiped clean upon sliding movement thereof within said pad, said dipstick extending beyond said one end for measuring the level of oil into which it extends.
Claim 10
Dependent Claim 66 words
An oil dipstick cleaning device, comprising an elongated portable jacket having a cleaning pad disposed therein near one end thereof, an oil dipstick extending through said jacket and through an opening provided in said pad, whereby said dipstick may be wiped clean upon sliding movement thereof within said pad, said dipstick extending beyond said one end for measuring the level of oil into which it extends.
