Abstract: A rack and pinion steering gear of the kind in which a helical pinion engages a rack mounted in bearings, the rack being supported opposite the pinion by a spring loaded half round support journal, the spring acting to hold the pinion in contact with the teeth of the rack which are formed in such a manner as to provide in about the center of the rack a "ramp" in which there are tooth gaps of varying height providing a variation of slack free mesh center distance between the pinion and the rack, the maximum mesh center distance occurring in the mid travel portion of the rack and lesser mesh center distances occurring in positions of travel of the rack either side of the travel position of the present invention being characterized by the fact that the tooth gaps concerned are formed in such a manner as to form a ramp extending across the rack at an angle substantially the same as the angle made by the pinion axis with the rack axis whereby the possibility of an uneven distribution of the load between the teeth

Abstract: An automatic transmission includes a fluid torque converter and a first and a second gear transmission mechanism, each of which has two coaxial drive members--a power input member and a power output member--and is selectable to any one of several speed ratios. Rotational power is output from the fluid torque converter to the first gear transmission mechanism. The torque converter, and the first gear transmission mechanism including the power input and power output members thereof, are all coaxial on a first axis. A through lay shaft extends along a second axis parallel to the first axis, passing through the second gear transmission mechanism so as to support it, and is rotationally coupled to the power input member of the second gear transmission mechanism.

Abstract: This is a security device to be attached to an inside security grill. It would protect the unauthorized entry of individuals and provide emergency departure from a secured area. It is a sequentially operated keyless lock primarily for use as an escape device but has application on automobiles, medicine cabinets, closets and childproof areas as it makes access difficult. It is sequential in that opening the lock requires the use of both hands and three physical movements. Step One must be done and remain stationary before Step Two can be accomplished. While Step One still remains stationary and after Step Two is completed, only then can Step Three be completed, opening the lock. If the sequence is interrupted before completion, the lock cannot be opened.

Abstract: A rack and pinion apparatus has lubrication for the rack (14) provided by a split bush (20) of graphite or other solid lubricant. The bush is pressed into contact with the surface of the rack by means of a circumferential spring (22), a sealing lip (23) being provided between the spring (22) and the bush (20) to seal the interior of the apparatus against dust and other foreign matter. The graphite lubricates not only the bearing surfaces (15 and 16) for the rack (14) but also the teeth on the rack and the pinion (11).

Abstract: A device which, when manually operated, will automatically return to an original position wherein a manually-operated control lever rotates at least one shaft having an arm mounted on the end of the shaft, and with a roll at the other end of the arm which abuts against one of two profiled parts when the shaft is rotated by the control lever. The two profiled parts resiliently abut a stop or stops when the arm is in an original or zero position but one profiled part abuts a stop while the other profiled part resiliently abuts the roll on the end of the arm when the shaft is rotated, and the profiled parts have steps thereon which are position markings able to be sensed manually by the control lever by a snap effect.

Abstract: A method and apparatus are provided for lubricating a sun gear 32 connected to a hollow coupling shaft 30 which is adapted to be joined to a source of rotational energy. The shaft 30 defines at least one opening 90 intermediate its ends which is adapted to receive a source 92 of lubricating fluid under pressure periodically throughout the rotational cycle of the shaft. By damming 108 the periphery of the opening on the interior of the shaft 30, the film of lubricating fluid formed along the interior surface of the shaft by centrifugal force is precluded from draining out of the opening 90 when that opening is not supplied with lubricating fluid under pressure. Channels 142 are provided across the walls 96 of the shaft to distribute the lubricating fluid thereformed axially towards the sun gear 32.

Abstract: A gear transmission mechanism for an automotive vehicle, with a power input shaft, including several combination assemblies, each including a layshaft and a selectively engagable friction engaging mechanism which can either be engaged to rotationally drive the layshaft from the power input shaft or can be disengaged to rotationally disengage the layshaft from the power input shaft. All the layshafts are substantially parallel with one another and with a mainshaft. Each of several pairs of gear wheels consists of a mainshaft gear mounted on the mainshaft and a layshaft gear mounted on one of the layshafts. Of each of these pairs, one is a fixed gear which is fixed to its shaft on which it is mounted, and the other is an idler gear which, according to the selective operation of a gear engaging system, either can be rotationally coupled to its shaft on which it is mounted, or can be left rotationally disengaged from that shaft.

Abstract: An improved control assembly is disclosed which is particularly suited for embodiment as a so-called mono stick control for a material handling implement. The control assembly includes a lever support member adapted to be pivotally mounted on an associated implement, and which carries a first control lever adapted to pivot with respect to the support member about a first pivot axis. The support member further carries a second control lever which is adapted for pivotal movement about a second axis parallel to and spaced from the first axis. Notably, the second control lever is operatively interconnected with the first control lever such that relatively large angular movement of the second lever results in a relatively lesser angular movement of the first control lever, with the second lever then acting to prevent movement of the first lever back into its neutral position.

Sealing rings are clamped between the outer periphery of each supporting member and the case, and additional sealing rings are clamped between each pipe and the supporting member, respectively.

Abstract: Apparatus for lifting a load through an arc includes two pivotally connected, overlapping housings which are pivoted relative to each other by a fluid operated piston disposed between the housings. The housings have overlapping sides provided with oppositely inclined cam tracks. Rollers driven by the piston and captured within the cam tracks transmit force between the sidewalls of the housings, thereby causing the housings to pivot relative to each other. One of the housings is adapted to have the load mounted thereon.

Abstract: The sub-assembly includes a telescopically arranged rotatable driving shaft and rotatable driven shaft. Both shafts are substantially triangular in cross-section. A spring provides a pre-determined spring force having a magnitude to permit one shaft to slide within the other shaft. The complementary triangular shapes of the shafts causes the torque from the driving shaft to be transmitted to the driven shaft without rotational lash.
