The device includes a fluid storage tank, a container for holding fluid to be recycled, a funnel having an anti-splash mat positioned therein to prevent the splashing of fluid being drained, and a valve means operative to direct the fluid to either the storage tank or to the recycle container for subsequent reintroduction into the vehicle. The valve means also includes means for connecting an air compressor to the storage tank so that compressed air may enter the tank and expel the fluid therefrom through a hose. The storage tank is mounted on casters for mobility and the size of the funnel's opening is sufficiently large to capture fluid flowing from widely spaced sources.

Abstract: To control the viscosity of oil circulating in a forced-oil circulation path of an engine, oil is conducted to a receptacle located, for example, within the oil pan of the engine or in communication with the overflow outlet stub (14) of the oil pump (3), and oil is conducted from this intermediate receptacle, for example in form of a pan (6) in two parallel paths. One of the paths conducts the oil directly to the suction inlet of the pump after, however, having to overcome a static pressure, for example by flowing over an elevated weir, notch, or through an overpressure valve; the other path is through a flow resistance element (7), for example a constricted tube, a lamella package, or the like, and then to the cooling portion of the oil pan, remote from the suction inlet of the pump.

Abstract: The present invention provides a motor oil change kit, especially for use by do-it-yourselfers, in which all that is needed for conveniently and cleanly changing the oil may be packaged together in a way that increases the chances that the motorist will not become intimidated by the project, but become habituated to this way of getting the oil changed, and that increases the chances that the motorist will unerringly bring the used oil to an authorized collection facility. Four types of kit are shown, each with its own advantages, but with many features in common. Each provides a closeable container of new oil, a collector for used oil, and a convenient system for either closing the container used for collecting the used oil, or for transferring the used oil from the collector to the emptied closeable container in which the new oil had been contained.

In view of the close proximity of the recesses with the movement of the crank web, very little oil reaches the insert.

Abstract: An oil catch pan is provided as a self-supporting structure having a bottom wall and an upstanding peripheral sidewall with a rim where the pan is open at the top. The pan is designed to be slid under an automotive motor vehicle and used to catch the oil being drained from the crankcase. The bottom wall of the pan is initially provided with a closure which is designed to be effectively opened, e.g. by pulling a conveniently located tab or by interaction with a piercing structure which is fitted between the pan and the jug.

The skimmer and tray mount to the engine separately from the pan. An alternate embodiment of a dry sump pan has a removable partition between a side pouch and the rotating parts and a skimmer separate from the pan. Separating the skimmer from the pan permits easy adjustment of the space between the skimmer and the rotating parts of the engine without obstruction from the pan.

Abstract: A drip pan for vehicles is made so that it can be used individually or assembled with other identical pans in an array to catch drippings from automobiles or trucks when they are parked. The pans have relatively low walls because the volume of dripping is not substantial, and when made of suitable plastic the pans can be driven over without damaging them. At least one end and one side of the pan are provided with a curved overhanging lip, the outer end of which will overlap the upper edges of walls of another pan which do not have such a lip, so that an array of pans can be formed to cover a large area if desired. The assembly of pans together is easily done and the drippings that normally fall in the junction area between pans are divided by the lips into one or the other of the pans so that the floor is not soiled.

Abstract: An engine sump 4 has an oil suction passage 7 formed in its side wall to communicate with the sump well 6 at its lower end and to open upwards at its upper end to communicate with a passage in a crankcase 3. Preferably, the passage 7 opens into an upwardly opening gallery 13 in the top of the sump wall along part of its length. Two such oil suction pipes 7, 8 may be provided at opposite locations relative to a central point so that the sump 4 can be rotated 180 degrees about this point from one fitting position to another. A filter element 11 may be provided in the oil suction passage 7 and held therein by the crankcase 3.

In one embodiment, the perforated work surface and catch basin form a detachable section for use in conjunction with existing stationary workbenches. The perforated work surface is coupled to the frame structure by a hinge which permits the work surface to swing away from the catch basin for easy access thereto. The position of this hinge and the supporting structure is such that the weight of the work surface and any objects that may be placed thereon is entirely supported by the stand structure and not by the hinge.

Abstract: A lubricator for an angle drive attachment for pneumatic rotary tools is disclosed. An output shaft of the angle drive attachment is surrounded by a stationary lubricating sleeve. The lubricator can include an upper portion and a lower portion formed of different absorbent materials.

The lower portion of the lubricator can be formed of a less absorbent porous material such as open cell styrofoam to slowly meter the lubricant onto the gears through capillary action. Alternatively, the angle drive lubricator can be formed of a single piece of absorbent material.

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.

Abstract: An internal combustion engine has an oil pan divided into two chambers that communicate with each other. The first chamber is at a distance above the bottom of the oil pan, which is also the bottom of the second chamber. Because the bottom of the oil pan is cooled by the slip stream the oil in the two chambers are at different temperatures. Suction lines lead from each chamber to a thermostat valve that connects them to a discharge line. The thermostat valve operates such that when the engine is cold the oil supplied to the discharge line is relatively hot oil from the first chamber and when the engine is hot the relatively cool oil from the second chamber is supplied via the valve.
