Abstract: A bale and grain feeder device includes an elongate conveyor and table structure which is mounted on the mixer-grinder vehicle chassis. The conveyor and table structure may be positioned to discharge slabs of hay and loose grain into the hammer mill of the mixer-grinder vehicle to permit such material to be chopped or ground into small pieces. A feed chute positions the baled hay on a conveyor and table structure to permit conveyor chains having paddles thereon to rip away portions of the bale. The feed chute may be removed for use with small grains or ear corn. A slab feeder roll cooperates with the conveyor paddles to convey the slabs of hay along the table where the hay or grain is directed to the hammer mill by paddles. A finger roll is used in the inlet area to precisely control the rate at which the bale is fed downwardly.

Abstract: An apparatus for harvesting and windrowing of corn utilizes one or more conveyor units swingably mounted to a corn harvesting implement such as a combine or corn picker and has horizontally moving cutting means carried forwardly of the conveyor units. As the implement moves through a field of standing corn, the cutting means severs the cornstalks as harvesting heads on the implement engage the stalk and strip the corn ears from the stalk. The conveyors receive and transport the severed stalks to a cornstalk discharge location between the conveyor units to create a cornstalk windrow along the path of the traveling implement. Corn plant residue, such as leaves, kernels, ear husks and the like, resulting from husking, are discharged from the implement and guided by deflector plates onto the windrow to be retained there for curing and later pickup.

Abstract: Exhaust system control apparatus operative to automatically close a damper in an exhaust duct leading from a spray booth when the spray booth is not in operation. A reversible damper motor is energized to rotate the damper to an open position when the spray booth is in operation. The damper motor is automatically reversed to close the damper in response to termination of spray booth operation. Energy is thus conserved by reducing the amount of heated air that would otherwise escape through the exhaust duct when the spray booth is not being used.In case of fire, the same damper is automatically rotated to a closed position in the exhaust duct by a spring loaded sprocket assembly on the damper shaft. This safety action takes place in response to the melting of a fusible link located in the exhaust duct and connected to a sprocket retention cable.

Abstract: A jack device for boat trailers and the like includes a bracket which is attached to the trailer frame or trailer bed. An extensible and retractable telescoping leg pivoted on the bracket and has a length greater than the radius of the trailer wheel. When the leg is swung downwardly from a transport position to a lowered position, and the trailer is then moved, the leg will be pivoted and extended to a vertical load supporting position to support the trailer so that the wheel is elevated above the ground surface. Conversely, when the leg is swung to the transport position, a spring telescopically retracts the leg in the lowered load supporting position. A foot member pivoted to the leg assures planar contact of the leg with the ground surface.

Abstract: The device of the invention utilizes an adjustably positionable mercury switch to actuate a solenoid which in turn releases the line on the spinning reel in response to the reel reaching a predetermined angle or position in the casting motion.

The louvered vanes also provide for improved rearward vision from the cab of the pickup and are especially useful for trailer hookups.

Abstract: A system of waste treatment and disposal which receives and completely destroys waste solids biochemically and disposes of the effluent by total evaporation within a sealed dispersion reservoir surrounding a two stage tank assembly. Raw sewage is reduced in first and second stages of anaerobic digestion in upper and lower tank units of a double tank assembly. Liquid effluent is forced outwardly through discharge openings in the lower tank unit and upwardly through a rock bed in the dispersion reservoir under the pressure of a liquid column in the upper tank unit. The liquid effluent evaporates in the rock bed as a third stage of disposal, with the resulting vapors being filtered through a sand bed over the rock bed and dispersed to the atmosphere in a fourth and final stage.

Abstract: An improved sorting apparatus of the harp screen variety utilizes a plurality of elongated, parallel wire spacing strips positioned along a frame and carried on individual beams which are oriented perpendicular to a multiplicity of tensioned wire lengths extending between wire retaining means at opposed ends of the frame. Each spacing strip has a substantially arcuate, convex upper face with a multiplicity of V-cross section wire receiving guideways which are equally spaced therealong to maintain a predetermined distance of separation between the wire lengths. Each guideway has an arcuate floor which has a convex arch configuration which supports the wire length at the apex of the arch and then drops downwardly to thereby minimize destructive abrasion between wire and guideway floor. The guideway construction tends to reduce wear of the guideway in lateral directions and to utilize normal wear to more firmly seat the wire in the guideway and retain desired spacing between adjacent wires.
