Abstract: An impeller assembly having a housing supporting a rotatable impeller. The housing has a bottom entrance opening and a top exit opening separated by a curved back wall. A liner of low friction and abrasion resistant plastic material located adjacent a portion of the inside of the back wall prevents material buildup on the back wall. The liner is removeably mounted on the housing so that it can be replaced without taking the housing apart. The impeller has a plurality of pivoted paddle assemblies. Each paddle assembly has a body carrying a generally U-shaped liner of low friction and abrasion resistant material to minimize the collection of material on the paddle assemblies. The housing includes a knife adjacent the entrance opening. The body of the impeller assembly has a transverse lip that moves in close relation relative to the knife to cut material.

Abstract: An impeller assembly having a housing supporting a rotatable impeller. The housing has a bottom entrance opening and a top exit opening separated by a curved back wall. A liner of low friction and abrasive resistant plastic material covers the inside of the back wall. The liner is removeably mounted on the housing so that it can be replaced without taking the housing apart. The impeller has a plurality of pivoted paddle assemblies. Each paddle assembly has a generally U-shaped liner of low friction and abrasion resistant material.

Abstract: A particulate material mixer has a rotatable drum with an inclined longitudinal axis. A conveyor having an open top trough and auger is located longitudinally in the drum and operates to move mixed material from the drum chamber into a hopper or alternatively back into the chamber. A drive transmission simultaneously rotates the drum and operates the conveyor. A flexible circular seal interposed between an annular end wall and a circular wall of the drum prevents material from spilling out of the drum. The conveyor trough is mounted for angular movement to regulate the volume of material discharged from the mixer. A manually operated liner actuator allows the operator to select the angular position of the trough. The hopper has a discharge door and chute to direct mixed material away from the mixer to a desired location.

Abstract: A silo unloader has an auger collector for moving material to an impeller operable to discharge material from a tower silo. A sprocket and endless chain secured to a transition assembly mounted on the impeller drives the collector around the silo wall. Wheels on the outer end of the collector and wheels on a biased arm on the inner end of the frame stabilize the unloader in the silo. A stop pivotally connected to the collector limits its backward movement by lifting the collector from the material.

Abstract: A bottom unloader having a material conveyor for moving material from a hopper centrally located in a bin to a location outside of the bin. A drive apparatus mounted on the outer end of the conveyor operates the conveyor and adjusts the tension on the conveyor chain. The outer end of the conveyor has a door that is clamped to a closed position with eccentric clamping locks. An elongated auger collector is mounted on a rotatable turntable located in the central hopper. A cap having a side opening for the auger collector is mounted on the turntable. The auger collector is drivably connected with the conveyor so that, when the conveyor is operated, the auger collector is rotated. A separate drive operated with a hydraulic motor is used to move the auger collector in a circular path.

Abstract: A livestock feeding apparatus having an endless belt supported on an elongated table above a feed bunk by a plurality of stands. The stands are laterally and vertically adjustable to level the apparatus and accommodate different sized bunks. The belt has an upper run that rides on a wood deck secured to the support. An idler pulley and drive pulley engages one end of the belt opposite ends. The belt is retained in driving engagement with the drive pulley by a driven roller engageable with the lower run of the belt adjacent the drive pulley. A motor drives the roller at a speed so that the surface speed of the roller is greater than the linear speed of the belt to maintain the lower portion of the run of the belt between the roller and the drive pulley under tension. A sweep assembly slidably mounted on the wood deck operates to move the material off of the side of the top run of the belt into the bunk.

Abstract: A motor vehicle having a pair of front drive wheels and a rear steerable drive wheel mounted on a main frame. A sub-frame secured to the main frame intermediate the front and rear drive wheels carries an internal combustion engine and a pump assembly. The pump assembly has a first pump operable to deliver fluid under pressure to fluid operated motors operably connected to the front drive wheels and a second pump operable to deliver fluid under pressure to a fluid operated motor operably connected to the rear drive wheel. The internal combustion engine and pump assembly are located below a seat and floor with both the engine and pump assembly positioned transversely of the main frame of the vehicle. The rear wheel is mounted on the frame for angular movement about a generally upright axis. A fluid operated double acting piston and cylinder assembly operates to angularly move the rear wheel about the upright axis to steer the vehicle.

Abstract: A mixer having an open top mixing box accommodating a pair of lower augers and a pair of upper paddle conveyors drivably connected to the augers. A power box pivotally mounted on one end of the mixing box is drivably connected to the augers with releasable drive connections. The power box is a motor driven power transmission assembly that can be disconnected from the augers and removed from the mixing box. A movable door associated with the bottom of the mixing box is used to selectively open and close a discharge opening allowing mixed and blended material to be discharged into a conveyor.

Abstract: A material conveying apparatus having a trough assembly for receiving material connected to a tail section. The tail section has a door movable to an open position to facilitate the cleaning of the tail section. An incline section connects the trough section to an elevator section. The incline section has conveyor guide strips that guide a movable conveyor in an arcuate path to the elevator section. The elevator section is connected to a decline assembly having a wear strip for guiding and supporting the movable conveyor. A discharge section is connected to the decline section. The drive for the movable conveyor is mounted on the discharge section.

Abstract: A top unloading silo unloader pendently supported in a tower silo. The unloader has a material collector moved around the silo with leading and trailing drive wheels. An impeller receives material from the collector and throws the material into an out chute which directs the material to a doorway leading to an upright passageway. The drive wheels are mounted on opposite ends of a rocker arm rotatably supported on a support. The support is connected to the impeller housing. Power is applied to both wheels by separate drive shafts connected to a gear box. A collector leveling apparatus has a linear actuator connected to the unloader frame. A cable connects the linear actuator with the outer end of the collector and the support in a manner so that the outer end of the collector can be raised or lowered and held in a selected position in response to operation of the actuator. The linear actuator has a reversible electric motor coupled to a motor controller.
