73862453, 73 7, 73 8, 731181, 73812

Abstract:

The apparatus is a multi-speed flat belt durability tester that can simultaneously test several belts of different lengths. The tester can apply different tensions to each belt with a tension pulley powered by a hydraulic cylinder, and it monitors the tracking of the belts with photocell sensors. At least two belt test positions located at the outer edges of the apparatus include cantilevered pulley ends that greatly facilitate installation and removal of the belts being tested.

Abstract:

The disclosure relates to a cab roof for an agricultural combine. The invention consists of an outer roof. Affixed within the outer roof is a left inner roof, right inner roof and a headliner. The left inner roof contains a fresh air duct with a fresh air inlet for the heating, ventilation and air conditioning (HVAC) unit. The left inner roof also has three light pockets. Each pocket contains either a distance or flood light fixture. Each light pocket also contains a light shroud having a top lip and an elongated bottom lip. The elongated bottom lip prevents light from reflecting off the cab glass. The right inner roof is similarly designed. The headliner contains a pair of molded conditioned air ducts for smoothly transferring conditioned air to several side defrost vents and several front defrost vents. A mirror support bar passes through the left inner roof, headliner and right inner roof. The entire roof is secured to the cab by several bolts.

International Classification:

B62D 2510

US Classification:

180 6921

Abstract:

A rearwardly pivotable hood for enclosing a tractor engine is disclosed wherein a hinge member pivotally mounts the hood to the tractor chassis. The hinge member includes an upper hinge portion movably supported on a lower hinge portion, which is fixed to the chassis of the tractor. The upper hinge portion carries a generally transverse and horizontally extending hinge axis which is connected to the hood to allow a rearwardly pivotable movement thereof. An adjustment mechanism to provide a side-to-side movement of the hood includes a centrally positioned vertical pivot pin interconnecting the upper and lower hinge portions to define an axis of rotation about which the upper hinge portion is movable into a selected orientation relative to the lower hinge portion. A pair of bolts passing through slotted openings serve to clamp the upper and lower hinge portions together.

International Classification:

B62D 2510

US Classification:

180 692

Abstract:

A sealing apparatus for a tractor having a rearwardly pivotable hood for enclosing a tractor engine is disclosed wherein the top radiator seal is a closed cell foam seal affixed by adhesive to the hood structure to be compressed against the radiator when the hood is moved to the closed position. The radiator side seals are formed by rubber flapper seals bolted to the lateral sides of the radiator and compressed against the hood structure when the hood is moved to the closed position. The radiator side seals are oriented such that the pressure differential caused by the engine fan urges the side seals against the hood member. The sealing apparatus prevents hot air from re-circulating from the engine compartment to be passed back through the radiator.

Abstract:

The disclosure relates to a steering column which is capable of moving four ways. The steering column has a base support affixed to a horizontal cab floor. The base support has a steering motor. The steering column has an input shaft with a upper telescoping shaft. Attached to the upper telescoping shaft is the steering wheel. Also attached to the upper telescoping shaft is the upper input shaft. The first universal joint connects the upper input shaft to the inner input shaft. Torque is transferred by a key on the exterior circumference of the inner input shaft to a key slot on the interior circumference of the outer input shaft. The outer input shaft is connected to the lower input shaft by the second universal joint. The lower input shaft is connected to the steering motor. Attached to the base support is the lower pivot assembly.
