Abstract: A modular dynamometer includes a stator mounted to and disposed within a housing and the combustion of a shaft and a rotor also disposed within the housing. The shaft extends through the housing and is adapted for coupling to a prime mover. The housing is closed and is filled with a liquid coolant, such as water. Lateral panels of the housing may be removed after the coolant is drained out to permit one or more rotor/stator combinations to be positioned within the housing along the rotating shaft in an alternating manner. The rotors are attached to the shaft so as to rotate therewith, while the stators are mounted to the housing in a fixed manner. Rotor/stator modules may be easily added to or removed from the dynamometer to facilitate increasing or decreasing the dynamometer capacity permitting the modular dynamometer to test a wide range of prime mover output power.

Abstract: A grain cart includes an auger having a first lower section fixedly mounted to an inner portion of the cart and a second upper section pivotally mounted to an upper end of the first auger section and movable between a retracted, non-use position and an extended, use position. The auger's second section is folded inwardly and maintained in position within an upper portion of the grain cart by gravity when positioned in the retracted position. The second section of the auger is pivotally displaced outwardly to assume the extended, use position wherein the two auger sections are aligned and mechanically coupled for removal of grain from the cart, with the second auger section also maintained in this extended position by gravity. The first and second auger sections are coupled to a mounting plate so as to form an integral structure which is easily removed from and installed in the cart as a unit by means of a plurality of bolts coupling the mounting plate to a lateral wall of the cart.

Abstract: An improved power absorption device of the general Prony brake design is capable of either applying to a rotating shaft either a fixed force or a force proportional to its rotational speed or for measuring mechanical power transferred to a rotating shaft by a prime mover. A stator shaft aligned with the rotating shaft is sealed within a cylindrical drum which is coupled to the rotating shaft and rotated thereby. A hydraulic system actuates a plurality of pistons in radially outward directions so as to frictionally engage the inner surface of the rotating drum. The resulting heat build-up is transferred through the finned, high-heat transfer lateral walls of the drum to water in a tank in which the rotating drum is located. Brake lubrication is provided by a closed lubricant circulation system within the rotating drum capable of providing efficient, uniform lubrication of the brake surfaces.

Abstract: The stand includes a rectangular base having a pair of parallel beams or rails. A pair of clamp fasteners are mounted to each end of the beams; and they may be adjusted longitudinally of the rails. Support wheels are mounted to each clamp fastener for vertical adjustment. At each end of the base, a pair of the clamp fasteners carries a vertical box frame between the rails. Each box frame telescopically receives and guides an adjustable vertical extension or slide which may be raised by a hydraulic ram. The clamps are mounted off vertical center on the box frames, so they may be reversed for further vertical adjustment. Other elements may be mounted to the base rails by the clamp fasteners.
