Abstract: A clean grain and tailings conveying system for an agricultural combine, including a pan fixedly mounted beneath a lowermost sieve of a cleaning system. The pan includes a tailings receiving portion disposed below a peripheral edge portion of the sieve, for receiving tailings which fall downwardly from the edge portion during operation of the sieve, and a clean grain receiving portion disposed beneath the sieve for receiving clean grain which falls downwardly therethrough during the operation of the sieve. The pan includes at least one elongate collecting conveyor including a clean grain collecting portion which extends longitudinally through the clean grain receiving portion of the pan, and a tailings collecting portion which extends longitudinally through the tailings receiving portion, for separately receiving and collecting the clean grain and the tailings received by the pan, and conveying the clean grain and tailings to transfer conveyors that can also be part of the pan.

Abstract: An attachment for use with a vacuum cleaner, includes a suction nozzle, a conduit communicating the nozzle with the vacuum cleaner, and a support plate. A pivot joint connects the support plate to the suction nozzle. A cleaning sheet is selectively attached to the support plate for collecting dust and dirt to be cleaned.

Abstract: An adjustment mechanism for opening size of sieve segments of the cleaning system of an agricultural combine disposed in end to end relation, which allows jointly adjusting the sieve sizes, or separate adjustment, and which allows easy and convenient removal and reinstallation of the sieve segments. The mechanism includes an adjusting element in connection with each of the sieve segments, which is movable in a predetermined manner for effecting adjustments in the opening size thereof. Connecting elements connect together the adjusting elements for joint adjustment, and are disconnectable to allow individual adjustment. The predetermined manner of movement can be, for instance, a simple rotational movement, and the connecting elements can include and elongate connecting element, such as a rod or tube which can extend over a substantial portion of the sieve segments.

Abstract: A textured trough element including a concave surface having a curved profile when viewed from a longitudinal end thereof of marginally larger diametrical extent than the circular cross section of a helical tailings auger. The trough element is positionable in a bottom portion of an auger trough with the concave surface facing and extending partially around a bottom portion of the helical radial outer periphery of the auger such that the auger will convey the tailings on and along the concave surface. The concave surface has a sufficiently rough surface texture for causing tumbling and rolling of at least a substantial portion of the tailings conveyed thereover, for loosening and releasing at least some of any grain partially or fully contained in elements of the tailings.

Abstract: An agricultural combine including an unloading system wherein an unloading conduit assembly is, in an operational set-up, rotatable or swivelable through an arc of 360° to permit grain unloading into a grain truck located at any point around the combine, whether the combine is stationary or moving. For road travel or storage the unloading conduit assembly, or some portion of it, is pivoted into a set-up wherein the longitudinal conduit is retracted into nesting relationship against the side of the combine and below the top of the grain tank.

Abstract: A vacuum cleaner has a suction nozzle, a housing connected to the suction nozzle and a suction fan and motor assembly mounted to the housing. A dirt collecting receptacle is mounted to the housing and is in communication with the suction nozzle and suction fan and motor assembly. A support plate is pivotally mounted to the housing and selectively holds a cleaning sheet for collecting dust and debris from a surface to be cleaned.

Abstract: A cab arrangement for a harvesting combine includes a harvesting combine having a body and a cab spaced-apart from the body. A platform is positioned between the cab and the body. The cab, the boy, and the platform define a passageway to allow an operator to visually monitor and access the body from the platform.

Abstract: A vacuum cleaner has a suction nozzle, a housing connected to the suction nozzle and a suction fan and motor assembly mounted to the housing. A dirt collecting receptacle is mounted to the housing and is in communication with the suction nozzle and suction fan and motor assembly. A support plate is pivotally mounted to the housing and selectively holds a cleaning sheet for collecting dust and debris from a surface to be cleaned.

Abstract: An agricultural combine in which each of the front wheels and each of the rear wheels is driven by an independent fluid motor. The front wheels are steerable and the rear wheels are steerable, either independently or together. Regardless of the use mode in which the combine is operating the weight and balance characteristics of the combine for that use mode are such that the location of the CG is optimized.

Abstract: A grain delivery conveyor for a grain tank of an agricultural combine includes a first gear box including a first input connectable in rotatably driven relation to a rotatable power source for rotation about a first axis, and a first output rotatable about a second axis angularly related to the first axis by rotation of the first rotatable input; a second gear box including a second rotatable input connected in rotatably driven relation to the first output for rotation about the second axis, and a second output rotatably driveable about a third axis angularly related to the second axis by rotation of the second rotatable input; and an elongate conveyor assembly connected in rotatably driven relation to the second output, the second gear box and the conveyor being jointly pivotable about at least the second axis for varying a position of a free end of the conveyor relative to the grain tank.

Abstract: An upright vacuum cleaner includes a nozzle base having a main suction opening formed in an underside thereof. A housing is hingedly connected to the nozzle base. The housing includes a dirt separation chamber and a dirt receptacle for receiving dirt and dust separated by the dirt separation chamber. A conduit connects the nozzle base to the housing. A suction source is located in one of the housing and the nozzle base. The suction source is in fluid communication with the dirt separation chamber. A generally conically shaped filter extends into the dirt separation chamber along a longitudinal axis of the dirt separation chamber.

Abstract: A bagless canister vacuum cleaner includes a selectively removable dirt cup, and an airstream flows rotationally through the dirt cup between an interior wall of the dirt cup and a filter assembly selectively mounted in the dirt cup so that entrained contaminants are separated from the airstream flowing through the dirt cup and collected by the dirt cup. The filter lies substantially parallel to the support surface on which the vacuum cleaner is supported. A cover member is connected to the main housing, and the cover member is selectively movable to and held in an operative position in covering relation with an open first end of a dirt cup. The main housing defines a base conformed to self-support the main housing on a support surface with the dirt cup arranged with its open first end at a higher elevation than its closed second end. The removable dirt cup includes a handle adapted for being held by a user, and the dirt cup defines or includes a spout to facilitate emptying dirt therefrom.

Abstract: An agricultural harvesting machine includes a tailings conveyor housing. The agricultural harvesting machine provides a cleaning device for cleaning threshed and separated grain. The tailings conveyor housing collects tailings from the cleaning device and propels the tailings with a first impeller against a first rethreshing member and radially to a second impeller. The second impeller propels the tailings against a second rethreshing member and radially to a third impeller. The third impeller propels the tailings against a third rethreshing member and radially through the second opening and past a baffle, where the tailings are redirected back to the cleaning device and spread out over the cleaning device.
