Patent number: 4386639Abstract: A normally closed drain valve is substituted for the normal drain plug in a conventional automobile crank case. Rather than remove the normally provided drain plug each time the oil is to be drained, it is only necessary to open the drain valve. Opening of this valve is accomplished by a specially designed coupler connected to a plastic bag. The arrangement is such that when the coupler is urged over the drain valve and twisted, the valve automatically opens to fill the bag with oil. The coupler can then be twisted back to its original position to close the drain valve and removed with the bag containing the oil. The entire operation can be accomplished only using one hand and with substantially no risk of oil spilling or soiling the operator.Type: GrantFiled: August 17, 1981Date of Patent: June 7, 1983Assignee: Sta-Lube, Inc.Inventors: Derek J. Gable, Roger H. Sweet, Nicol S. Wilson

Patent number: 4331185Abstract: Service personnel may confuse one dip stick for another in vehicles having a number of fluid reservoirs. When the reservoirs have air entrapped within them during filling, hydraulic lock can occur. Herein, a filler tube structure (20) and a dip stick tube structure (30) have their top ends held within a tubular fitting (40) which is covered by a single cap (58). This eliminates any possible confusion as to the dip stick tube structure (30) which corresponds to a particular reservoir or chamber (12). In the preferred embodiment venting of the chamber (12) to which the fluid is being added is provided via an interior passage (32) of the dip stick tube structure (30), thus preventing hydraulic lock.Type: GrantFiled: July 14, 1980Date of Patent: May 25, 1982Assignee: Caterpillar Tractor Co.Inventors: James D.

Patent number: 4301841Abstract: A multipurpose container for storing, transporting, collecting and disposing of fluids such as motor oil and the like. The multipurpose hollow container includes a top wall, a bottom wall and four connected generally rectangular side walls enclosing the interior. In the top wall is a first threaded pouring outlet having a cooperating removable sealing cap for pouring of the fluids. One side wall is concave shaped with a second threaded opening formed thereon for communication with the interior of the container for providing a funnel for collecting the spent fluid and flowing that fluid into the interior of the container. The second opening is located substantially away from and with its lowermost edge below the first opening which vents the interior to avoid splattering and minimizes overflow spillage. A perforable membrane is secured over the second opening by a removable plug to avoid leads during storage while a handle is provided to aid in transporting and placement of the container.Type: GrantFiled: October 22, 1979Date of Patent: November 24, 1981Inventor: Kiyoshi Sandow

Patent number: 4073323Abstract: This invention relates to a deflector which is specifically utilizable with a receptacle having a plurality of openings for receiving one or more interconnecting tubings. The deflector includes a plate-like member which is sufficiently large to effectively block a first opening in the receptacle. The plate-like member is biased to a first position to block the first opening in the receptacle. An engagement or abutment member is arranged to project into a second opening in the receptacle to engage or abut the tube which is deflected by said plate member into the second opening in the receptacle. When the abutment member is abutted by a tube, the abutment member rotates around a given axis. The abutment member is appropriately connected to the plate-like member to cause this latter member to also rotate about the given axis such that the plate-like member is removed from blocking relationship relative to said first opening in the receptacle.Type: GrantFiled: June 30, 1976Date of Patent: February 14, 1978Inventor: Eldon D.

Patent number: 4044913Abstract: The invention relates to a valve mechanism for a liquid container, particularly a petrol tank of the kind in which an air-ventilating line between the tank and its filling pipe is closed during filling to build up an air pocket for limiting the filling level. The invention provides a simple construction in which the ventilating line opens into a recess formed in the wall of the filling pipe near to the filler cup. The opening is normally closed during filling by a seal carried by a spring retained in the recess, the spring having a part extending into the filling pipe such that, when fitted, an axial extension of the filler cap urges the spring, and hence the seal, to uncover the opening. In a preferred form, the recess extends transversely of the filling pipe and the spring is U-shaped and contained within the recess, that leg nearer the filler cap carrying the seal.Type: GrantFiled: February 19, 1976Date of Patent: August 30, 1977Assignee: Saab-Scania ABInventor: Stig Erik Brunnert
