Abstract: A flexible locking dipstick module useful with a motor vehicle including an oil reservoir. A dipstick is disposed within a housing which has one end thereof affixed to the oil reservoir and extends therefrom to a location within the engine compartment of a motor vehicle. The end of the module disposed within the engine compartment includes a quick disconnect locking coupling providing for ready installation and removal of the dipstick. The coupling further provides protection against blow out of the dipstick in the event of inordinate build up of pressure within the oil reservoir. Further, one portion of the outboard coupling may be employed as a liquid-tight closure for a dipstick entry opening in the oil reservoir during removal and/or storage of the engine.

An oil-level-gauge for measuring the amount of oil in the inside of the internal combustion engine extends within the oil-filler-port. The oil-level-gauge is formed integral with a cap for the oil-filler-port. A guide cylinder portion for guiding the gauge deep inside the oil-level-gauge attachment hole is provided to extend therein. A side outflow hole where the filled oil detours around the guide cylinder portion and directly flows down to the inside is formed on the way of the guide cylinder portion. A guide wall for preventing the gauge from entering the side outflow hole is formed on a lower portion of the side outflow hole.

The guide preferably has a longitudinal slot in the stem and cup, allowing the guide to be friction fit on the proximal end portion of the diptube or compressed around the proximal end portion of a dip tube. The guide is secured with a clamp that compresses the stem around the diptube, or the guide may have an integral clamp that compresses the stem around the diptube. The guide is preferably made from a molded, brightly colored plastic.

Abstract: A dipstick guide assembly for guiding a free end of a dipstick into a dipstick tube. The dipstick guide assembly comprises a clamp secured to an upper portion of the dipstick tube, a guide member and an adjustment mechanism for fixing the position of the guide member. The guide member has a portion removed therefrom so as to enable to aid in removing the dipstick from the guide member. The adjustment mechanism fixes the guide member in a position such that the distal end of a guided dipstick is introduced into the mouth of a dipstick tube.

Abstract: An oil level indicator assembly for a vehicle engine including an elongated indicator member removably housed in a tubular sleeve which has spaced upper end and lower end portions with an interior passage therebetween and an internal shoulder-like formation therein. The elongated indicator member has a coil spring formation adapted to engage the shoulder-like formation when the indicator and sleeve are in an assembled relationship, thereby establishing a predetermined length of the indicator to project into the engine oil. The effect of oil on indicia formed on the indicator member when withdrawn from the sleeve member shows the level of oil in the engine.

Abstract: An overfill prevention device for storage tanks includes an elongate tubular housing having a liquid flow passageway. A normally open main valve and a normally closed vapor retaining bleed valve are associated with the fluid passageway. Closure of the main valve interrupts the primary flow of liquid through the passageway and closure of the bleed valve prevents any further liquid from entering the tank and also prevents the escape of vapors from the tank. Operation of the main valve is controlled in significant part by a valve latch assembly which is carried by the housing and a relatch assembly which is carried by the main valve. The relatch assembly ensures operative engagement of the main valve with the valve latch assembly upon movement of the main valve from the intermediate position to the open position. Operation of the main valve and vapor retaining bleed valve is also controlled indirectly by a plurality of floats which are maintained in a float chamber extending adjacent the liquid passageway.

Abstract: There is disclosed a short and straight oil level gauge adapted for use with an automative automatic transmission. The gauge is inserted in an oil filler tube which is also short and straight. The tube has a flexible clamping member. The gauge has a rodlike body having two ribs, a cover at the upper end of the rodlike body, a plug portion located under the cover, a tool-connecting portion located above the cover, and insertion guide surfaces formed on the body and connecting the plug portion with the body. The tool-connecting portion is shaped like a socket, and a conventional socket wrench can be inserted into this tool-connecting portion. The insertion guide surfaces are formed by two ribs or fins radially extending from the rodlike body in mutually perpendicular directions. The guide surfaces cooperate with the inner surface of the tube to assure that the clamping member of the tube engages the cover.

Abstract: An apparatus for locating and guiding a dipstick used to measure the level of oil in a crankcase of an automobile engine and for wiping excess or residual oil from the dipstick. For existing vehicles, an adaptor is provided which is secured to the exterior of a dipstick tube. The adaptor has a lower section which engages the dipstick tube, an intermediate seciton to receive a cap member for the tube, and an upwardly extending funnel-shaped top section serving as an easy locator for the lower end of the dipstick. The upper edge of the funnel-shaped top section is provided with one or more wiper slots to wipe residual oil from the dipstick. For new automobiles, the dipstick tube is formed with a flared-funnel top which preferably terminates in a cylindrical vertical wall in which at least one wiper slot is provided. The handle of the dipstick is provided with a plug-like member from which the dipstick is subtended and which also carries a cover member to prevent excessive oil contamination.

Abstract: A dipstick guide to aid in the insertion of a dipstick into a dipstick tube when measuring the level of oil in the engine or replacing the dipstick in the dipstick tube comprising an upper frusto-conical body whose side converges into one end of a smaller central body or tube portion, the other end of which then diverges into a lower body or frusto-conical skirt, smaller than the upper body, the two opposed frusto-conical bodies having sides which diverge in opposite directions from each other, and a slot extending axially along the length of the guide from one end to the other to allow removal of the guide, sidewise, when the dipstick has been partially inserted into the dipstick tube. An upstanding handle on the upper body facilitates the positioning of the dipstick guide onto the dipstick tube, and allows for the dipstick guide to be manually removed from the dipstick tube, and then moved out of the way of the dipstick.
