  • Patent number: 5339677
    Abstract: A hydraulic hose impulse tester capable of simultaneously testing multiple samples of hydraulic hose in a stationary-impulse condition and in a flexing-impulse condition in the same test environment. The tester eliminates varying extraneous factors which can affect comparative test results by performing the static and dynamic tests simultaneously. Alternatively, all sample hoses can be tested in either a static or dynamic condition.

  • Patent number: 5309653
    Abstract: A snow deflection system for a snowplow includes an arcuate foil and a preferred belt. Both the foil and the belt are attached to the moldboard of the plow so that the preferred belt keeps the plowed snow close enough to the moldboard to allow the arcuate foil to direct the flow of snow and air, which blows over the top of the moldboard, down and away from the plow vehicle.

  • Patent number: 5308308
    Abstract: A card display pocket formed of three sheets of fusible material. The first sheet is a nylon/vinyl material that is slit one way to receive the second sheet of a frosty vinyl material which may be slit a different way from the first sheet to form specially designed pockets and woven through the first sheet of material, over the front side of the first sheet of material and under the back side of the first sheet of material. The third sheet is a plain vinyl that is used for a backing.The method of construction is as follows: In a sheet of nylon/vinyl material slits are made lengthwise or widthwise through the material so that they are either generally parallel to each other or generally perpendicular to each other. Translucent vinyl material, is then interwoven through these slits in order to form the desired pockets. The card pocket with curved sides is especially desirable for applications where a card is frequently accessed.

  • Patent number: 5224727
    Abstract: An anti-jackknifing system for use on a tractor having a fifth wheel and a trailer having a trailer pin. The anti-jackknifing system is made of a non-cylindrical pin attached to the existing trailer pin, and a freely rotating brake disk mechanism. The brake disk mechanism has a central shaft and a brake disk attached to the central shaft. A non-cylindrical opening at the top of the central shaft couples the trailer to the brake disk mechanism so that the brake disk mechanism rotates when the trailer rotates. When the tractor brakes are applied, a braking system stops rotation of the brake disk.

  • Patent number: 5219069
    Abstract: A coin holder made of plastic, or another suitably flexible material, having a flexible base, a flexible wall extending at a right angle from the base, a T-shaped tab extending outwardly from the base, and one or more tab-receiving slots in the base. The base and wall form a recess into which a coin may be fitted. The slots accept the T-shaped tab of another coin holder at an angle, and lock the coin holders together when the angle is reduced. In addition, the invention includes a flexible band into which coin holders may be attached for holding and display by being anchored parallel to the flexible band, or hanging freely from the flexible band.

  • Patent number: 5197569
    Abstract: The present invention is an apparatus for regulating the amonut of oil, lubricant, or other type of lubricant applied to a surface of a work piece in order to reduce friction during a machining process. It comprises a primary reservoir, a needle valve, float assembly, a liquid drop control orifice, a sight for allowing visual confirmation of the flow rate, an atmospheric vent, an inlet for pressurized air, and a nozzle. The needle valve is slidably engaged into an orifice in the primary reservoir and is actuated by the float assembly. The float assembly floats in the low volume constant depth reservoir and controls the degree to which the needle valve need be open in order to maintain a constant volume of lubricant in the low volume constant depth reservoir. As the volume increases to the required level, the needle valve will close. As the volume decreases, the needle valve will open in order to maintain a constant level of lubricant in the reservoir.

  • Patent number: 5197786
    Abstract: A rigid cambered drive axle has a straight rigid housing for the two drive axles and a cambered spindle, integral with the end of the housing, for supporting a wheel hub. A drive in each inside of the housing turns a cambered drive plate through a direction changing ball joint. The drive axle and the cambered spindle each have an axis that intersects the other at the direction changing drive ball joint. The axle housing is provided with internal bearing seats concentric with the drive ball joint. The axle housing is provided with internal bearing seats concentric with the drive axle and with the external bearing seats concentric with the wheel hub. The spindle supports the wheel hub at a degree of camber equal to the angle formed by the intersection of the central axes of the spindle and the drive axle, whereby the degree of camber of the wheel hub is kept constant.

  • Patent number: 5191678
    Abstract: A spring loaded door hinge comprising a rod that moves with the door as the door pivots. Attached to the door frame is a flange. The door is attached to the rod by means of collars. The tails of the coil springs extend from the rod so that they may, depending upon their position, be in position to strike the door frame flange thereby preventing a large shock from being transferred to the door if it is swung open violently. Also the spring hinge allows the door to be easily opened initially with resistance to the door opening being controlled by the positioning of the tails of the coil springs. The springs are distributed vertically to prevent twisting of the door and frame. The tails of the spring coils are hooked so that the can engage the door frame flange if extreme force is placed upon the door when opening. The hooks set a limit as to how far the door may be opened and prevent the spring tail from binding between the flange and the spring coil.

  • Patent number: 5169367
    Abstract: A drive chain assembly for vehicles having two chains, an idler sprocket, and a thrust link or strut. The first chain extending from the vehicle motor to the idler sprocket. The second chain extending from the idler sprocket to a driven axle sprocket. The second chain extending downwardly at a substantial angle from the driven axle to the idler sprocket and the idler sprocket supported on a mounting member which pivots on the same axis as the driven axle itself. The thrust link is pivotally attached at one end to the chassis of the vehicle near the engine and at its other end to the mounting of the idler sprocket. This strut forms one of the long side of a parallelogram linkage. The first short side of the parallelogram linkage is the distance between the pivot point at the engine end on the chassis for the strut and the engine sprocket. The second long side of the parallelogram is the first drive chain itself.
