Abstract: The transmission shift control mechanism includes a shift lever with a pushbutton mechanism for releasing a detent mechanism so that the shift lever can be moved from the "Park" position to other operative positions. A shift lever locking mechanism prevents movement of the shift lever from the "Park" position when the ignition lock mechanism is actuated to the "Lock" position and also prevents actuation of the ignition lock mechanism to the "Lock" position when the shift lever is in other than the "Park" position. The locking mechanism includes a pivotal locking lever, such as a bellcrank, having one arm operably connected to the push-pull cable of the vehicle ignition lock mechanism and a locking arm movable to block release of the detent mechanism upon actuation of the ignition lock mechanism to the "Lock" position with the shift lever in "Park".

Abstract: Presented is a fluid-operated control device that may be operated by pressurized gas or liquid. A housing contains a double-acting piston assembly that is moveable in a longitudinal bore in the housing. A gear rack connects the two pistons. A rotor assembly in the housing includes a pinion gear meshing with the gear rack, and a second pinion gear meshes with a second gear rack attached to a slide member moveably supported on the housing. Thus, injection of fluid under pressure behind one or the other of the pistons causes axial translation of the pistons and connecting gear rack. Translation of the gear rack effects rotation of the rotor assembly, which in turn effects axial translation of the second gear rack to which is attached the slide member.

Abstract: A mechanism for generating oscillatory motion omnidirectionally transforms rotating motion in which the rotating member is continuously rotated unidirectionally into any number of simultaneous arcuate motions intersecting at predetermined angles. This mechanism includes a disk-shaped body rotatably mounted and swept in a circle so that it completes two periods of rotation over the course of one period of sweep. The altitude of the disk-shaped body always intersects a point on an imaginary line, regardless of the angle of inclination of the disk-shaped body. This imaginary line is perpendicular to the circularly swept path of the disk-shaped body at the center of the circularly swept path. Points on the circumferential edge of the disk-shaped body describe an infinite number of arcs as they move around the circularly swept path. These arcs intersect at a common point from an infinite number of angles.

Abstract: A lubrication system is provided for a transmission mechanism supported on input and output shafts, and a chain drive rotatably connects these shafts. The chain and drive elements on the shafts are provided with a casing for isolating the mechanism, which collects an oil bath within the bottom of the transmission casing for lubricating a chain or other transmission member. An oil pump supplies oil from a reservoir to various areas to be specifically lubricated within the transmission. Feed means associated with the oil pump regulates the level of the transmission oil bath. The system may additionally contain an oil strainer, an external cooler, a relief valve to limit the pressure from the oil pump, or various combinations of such elements. The various points of lubrication within the casing, in turn, drain into the casing. Oil level within the transmission casing is regulated to keep the level low and at the same time to maintain sufficient oil for lubricating the chain.

Abstract: A pump 11 is provided in a gear-shift mechanism, in particular a boat reversing gear transmission, in order to supply the hydraulically operated friction clutches with pressurized oil. The pump 11 sucks oil through a fine-mesh filter 19 out of the sump 21. The fine-mesh filter 19 is arranged in a separate filter chamber 12 which is connected through a suction pipe 13, 15 to the sump 21 and to the suction side of the pump 11. The two suction pipes are arranged in such a manner with respect to one another that the filter chamber 12 is always filled with oil. A dry running of the pump 11 during starting is avoided in this manner. The fine-mesh filter 19, in the form of a removable filter cartridge 20, allows the flow of oil from the inside thereof to the outside and is arranged for easy access from above.

Abstract: In a gear arrangement consisting of two gears meshed with each other, at least one gear is constructed of a teeth portion having teeth along its circumference and a shaft portion adapted to be mounted to a support shaft, a gap space is retained between the teeth portion and the shaft portion, and an elastic body such as an O-ring, an annular spring, etc. is interposed in the gap space. And a tooth thickness of one gear of the above-mentioned two gears is made larger than that of the other gear. When the above-described two gears are meshed with each other, the teeth portion of the gear having the elastic body interposed therein moves in the radial direction with respect to the shaft portion, and thereby the teeth of the respective gears can be meshed without backlash.

Abstract: A shaft slides within a tube. A relatively high-rate leaf spring is positioned to exert its force against the outer surface of the shaft. The leaf spring provides optimal sliding force between the shaft and the tube with minimum friction, while also functioning to minimize rotational lash. Indents located on the exterior surface of the tube are directed radially inward to further minimize rotational lash.
