Patent number: 4421194Abstract: A tubing assembly provided between two movable bodies such as front and rear body portions of a three-wheeled motor vehicle. The front body is laterally swingable relative to the rear body and these bodies are relatively movable along longitudinal and vertical directions thereof. The tubing assembly includes a first flexible tubular member extending substantially vertically and having one end connected to a first rigid tubular member of said front body portion, a second flexible tubular member extending substantially horizontally and having one end connected to a second rigid tubular member of said rear body portion, and a generally L-shaped intermediate rigid tubular member connected between said first and second flexible tubular members. The tubing assembly is positioned outwardly offset from a rotational center of said movable bodies and at the same longitudinal side of said vehicle.Type: GrantFiled: January 6, 1982Date of Patent: December 20, 1983Assignee: Honda Giken Kogyo Kabushiki KaishaInventor: Katsuyoshi Kawasaki

Patent number: 4368899Abstract: An automatic hitch mechanism that permits a tractor driver to connect and disconnect an implement without leaving the cab of the tractor. The hitch includes a tractor drawbar equipped with a power-driven slide member, hook member, and power coupling assembly all interconnected for coordinated movement so that during a hitching operation the hook member first swings into operative engagement with the latch ring of an implement and then, in a continuous sequence of automatic steps, the hook member is locked in its operative position, the power coupling assemblies of the tractor and implement are joined together, the jack supporting the implement tongue is retracted, and one of the coupling assemblies is de-stabilized so that thereafter the tractor and implement may execute turns and traverse uneven terrain without damaging or disengaging the coupling assemblies. Automatic unhitching of the tractor and implement involves a reversal in the direction and order of such steps.Type: GrantFiled: March 16, 1981Date of Patent: January 18, 1983Assignee: Kansas State University Research FoundationInventors: Edward A. Smalley, Mark J. Boguski, Todd A. Casey, Dwight D. Chipperfield

Patent number: 4366965Abstract: A keeper (10) is adapted for installation on a rear panel of a truck cab for holding a pair of gladhands (18,20) and an electric plug (22). The keeper is a one-piece unitary structure of molded plastic. It comprises a pair of gladhand receptacle members (32,33) and a plug receptacle member (34). The receptacle members are mounted on a panel of the cab by mounting brackets (24,26). The gladhand receptacle members (32,33) each defines a gladhand receptacle slot which receives a gladhand by insertion and rotation in a plane perpendicular to the mounting panel. The receptacle member (34) for the plug comprises a vertically disposed socket (50) between the pair of gladhand receptacle members (32,33).Type: GrantFiled: September 19, 1980Date of Patent: January 4, 1983Inventor: Murray G.

Patent number: 4253256Abstract: An improved reciprocatory self-loading dual-ended earth excavation vehicle pivotally connected to two or more unmanned self-leveling and self-maneuvering telescopic conveyor vehicles, the latter in turn are pivotally connected to a multi-function dual-ended distribution vehicle capable of conveying, spreading, wetting, impacting and grading the earth fill. The above-mentioned articulated vehicles provide the means to excavate, convey and discharge a virtually continuous flow of earth while traveling in a forward or rearward direction. The excavation and telescopic conveyor vehicles are readily adaptable to surface mining of various minerals including coal and oil shale by simply exchanging the above-mentioned distribution vehicle for a pivotally connected boom conveyer vehicle which provides the means for discharging the ore at a mill site or for the loading of long haul ore carriers.Type: GrantFiled: May 14, 1979Date of Patent: March 3, 1981Inventor: Jack M. Feliz

Patent number: 4234012Abstract: A backhoe swing frame is connected to a support frame by means of a vertical pivot assembly. A hose support bracket is mounted on the swing frame and supports a plurality of hoses extending across the vertical pivot assembly from the support frame for conveying hydraulic fluid to and from a plurality of hydraulic actuators of the backhoe. The hose support bracket comprises a base plate to which the lower end of an upright plate is fixed, the upright plate being inclined away from the pivot assembly. A plurality of vertically oriented tabs are fixed to opposite ends of the upright plate and are each provided with a horizontally opening notch, the tabs being dimensioned and located such that the notches are spaced vertically and fore-and-aft from each other.Type: GrantFiled: April 27, 1979Date of Patent: November 18, 1980Assignee: Deere & CompanyInventor: Jesse L.
