  • Patent number: 5992070
    Abstract: A flexible face sign system is provided which includes a cabinet assembly mounting one or two face assemblies. The cabinet assembly includes a cabinet frame comprising upper, lower and opposite side cabinet frame sections. The cabinet assembly can receive a light fixture for providing illumination. The face assembly includes a face frame comprising upper, lower and opposite side sections. The cabinet and face upper frame sections are hingedly interconnected whereby the face assembly can be swung to an open position with respect to the cabinet assembly. Alternatively, the face assembly can be removably mounted on the cabinet assembly without providing for hinged motion therebetween. The face assembly includes a flexible face panel mounted on the face frame sections and adjustably stretched thereover by retainer clips which grip margins of the face panel and are tension-adjustably connected to the face frame sections by tension-adjusting bolts.

  • Patent number: 5906482
    Abstract: A double wall vertical cooler designed for cooling extruded feed products and the like includes a cooling chamber with an upper cylindrical section and a lower frustoconical section. An outer wall surrounds the frustoconical section of the cooling chamber to form a cooling air circulating chamber. Apertures formed in a wall between the air circulating chamber and the cooling chamber allow cooling air to flow into the cooling chamber near the bottom with air flow exiting near the top as feed product is dropped from a product inlet in the top of the cooling chamber with product exiting at the bottom of the cooling chamber. The cooler design minimizes product breakage and enhances product throughput.

  • Patent number: 5896966
    Abstract: A seed clutch actuating hydraulic piston & cylinder unit for a seed drill is attached directly to a cam plate on the seed clutch. The clutch actuating piston & cylinder unit is linked to a hydraulic lifting system for the seed drill such that, when a tractor operator operates the hydraulic lift for the seed drill, the clutch actuating piston & cylinder unit is retracted (or extended), with the piston then immediately rotating the seed clutch cam plate, which disengages the seed clutch. The seed clutch thus disengages the seed metering drive shaft so that seed metering is immediately shut off as the seed drill starts to raise. As the operator lowers the seed drill back down to an operating position, the clutch actuating piston and cylinder unit is extended to rotate the seed clutch cam plate back to its original position, which engages the clutch to reconnect operative power to the seed metering shaft.

  • Patent number: 5890546
    Abstract: A tractor drawn scraper apparatus with folding wings includes a main frame with a main blade assembly depending therefrom and wing frames with wing blade assemblies depending therefrom. The wing frames are pivotally connected to laterally opposite ends of the main frame and are pivoted by the action of hydraulic cylinders connected between the main frame and the wing frames respectively. The wing frames are lowered for soil engagement and raised for transport. A wheel frame includes a wheel frame axle pivotally connected to the main frame by way of the main blade assembly and having a pair of radial wheel support arms with ground engaging wheels journaled thereon. A pair of wheel frame cylinders engaged between the main frame and the wheel support arms are activated to raise the wheels for soil engagement by the blade assemblies and to lower the wheels for transport. A tongue assembly extends forwardly from the main frame for hitching to a tractor to draw the blade assemblies over a soil surface.

  • Patent number: 5888044
    Abstract: A bulk seed cart includes a seed bin with sloping sides converging at a bottom mounted discharge hopper to which a conveyor is removably connected for unloading seed from the cart. The conveyor is supported by a telescoping boom mounted on the side of the cart and the boom, and attached conveyor, can be raised or lowered via an attached hydraulic lifting cylinder. The boom can be pivoted from side to side and the conveyor is attached to the boom via a swivel assembly, which, once the conveyor is detached from the seed cart, allows the conveyor to be swiveled 180 degrees and attached to a nearby source of seed, such as another seed cart, a stationary bin, a truck or railroad car, etc., with the conveyor being directed toward the seed bin in the seed cart. Seed can thus be unloaded from the source and loaded into the seed cart via the conveyor. The lifting cylinder, the telescoping boom and the conveyor motor are all controllable via a single remote control module.

  • Patent number: 5884513
    Abstract: A combination coin and key holder includes a coin holder housing which has an outline shaped as a vehicle. A closed loop is attached to the coin holder housing, preferably in the front end of the vehicle outline, for connection of a key ring, chain, or other key holding device thereto. A pair of coin slots are provided in the coin holder housing on the bottom side of the vehicle outline, with each slot being dimensioned to hold a specific coin. The coin slots are positioned and configured such that coins inserted thereon are reliably, yet removably retained in place, but such that they protrude sufficiently to have the appearance of a wheel or wheels on the vehicle outline.

  • Patent number: 5882063
    Abstract: A tractor canopy attachment system includes a pair of vertical mounting brackets which are attachable on respective upright posts of a tractor roll bar and a horizontal mounting bracket which is attachable to a cross member of the roll bar. A canopy attachment frame includes a cross member attached to the canopy near the rear thereof, with a mounting flange attached to the cross member which cooperates with the horizontal mounting bracket to hold the canopy in place on the roll bar. A pair of angled braces are attached to respective ends of the cross member, with each brace being removably attachable to a respective one of the vertical mounting brackets. A plurality of easily removable pins hold the canopy mounting flange in position on the horizontal bracket and a single pin holds each angled brace in position on its respective vertical mounting bracket. With the inventive installation system, the entire canopy structure is easily installed or removed in a few minutes by a lone operator.

  • Patent number: 5879631
    Abstract: A gas detection system and method selectively detects a gas in the presence of nonselected contaminant gases. The system includes a housing having a collection chamber and a sampling chamber containing a variable resister and a molecular sieve. A molecular sieve is positioned between the chambers for selectively passing a target gas from the collection chamber to the sampling chamber. An organic molecular sieve permits only selected low molecular weight gases, such as ammonia and carbon monoxide to come into contact with the sensor.

  • Patent number: 5878504
    Abstract: A rifle scope vertical alignment apparatus includes first and second plates, each with a bottom surface shaped as an inverted V. A vertically oriented elongate slot is formed in one of the first and second plates and a receiving channel is formed in one of the first and second plates to slidably engage the other of the first and second plates. A level is positioned on one of the first and second plates such that it is visible from a rear surface of the apparatus. A threaded screw extends through the slot and into a threaded bore on the other of the first and second plates so that the plates can be held in a selected position relative to each other with the inverted V bottom surfaces aligned. The alignment method involves positioning the inverted bottom V of the first plate of the alignment apparatus atop the rifle barrel just in front of the objective end of the scope, placing the inverted V bottom surface of the second plate atop the scope barrel and then tightening the threaded screw.

  • Patent number: 5873580
    Abstract: A tool holder for small hand tools such as screw driver sets, drill sets, etc., which tool holder has external threads near one end which accommodate a compression sleeve which fits over and compresses a tool holding collet/chuck. Within the tool holder is a female hex shaped receptacle which is sized to accommodate a male hex shaft of the collet/chuck. The hex shaped receptacle in the tool holder and the hex shafts of the collet/chuck's act to prevent the collet/chuck's from turning when the tool is subjected to high levels of torque and also allow collet/chuck to be easily interchanged so that a single tool holder can be used to accommodate tools with a variety of shaft cross-sectional shapes such as round, square, hexagonal, etc.
