Abstract: A feeding mechanism for a round hay baler is capable of feeding plastic sheet, netting, or alternatively twine by means of a single set of parallel feed rolls. The device includes a control mechanism which, upon sensing of a full bale having been formed within the baler, initiates a programmed control sequence beginning with driving of one roll for an incremental period of time. The driven roll engage netting, sheet or twine against the second idler roll and feeds the netting, sheet or twine into the bale forming mechanism for wrapping about the bale. Upon completion of the wrapping sequence, a special knife descends and cuts the twine or sheet of netting or plastic. The controller then resets the mechanism.

Abstract: A mechanism for connecting a trailing wheel to an implement, incorporates a spring arm which will absorb shock. The tension on the spring is adjustable.

Abstract: An improved farm implement includes a frame having a forwad hitch which is maintained at a fixed position relative to the remainder of the implement during all stages of operation. The rear end of the frame includes running gear which may be raised and lowered to raise and lower an array of discs and chisel plows in order to cultivate a field, particularly a field which may includes a great amount of field stubble.

Abstract: A round hay baler includes a forward pick-up assembly and hold down tines for gathering and introducing a layer of material into the baler. The hold down assembly includes fluid discharge tines extending from a hollow manifold connected to a reservoir that contains preservatives, nutrients or biological inhibitors, for example, which are added to the inside of the layer forming the round hay bale.

Abstract: The improvement in a gravity box farm wagon of a door opening mechanism for side opening discharge door of the farm wagon includes a hand wheel operated spool with cable wrapped around the spool and connected at its opposite ends to the door and a channel member extending vertically from the door.

Abstract: A wet sleeve insert in an internal combustion engine cylinder bore includes a circular conductive ring or spring which is inserted between the sleeve and the engine block to ensure conduction of electrostatic current to thereby prevent electrostatic pitting on the surface of the wet sleeve and ultimate cavitation of coolant flowing about the sleeve.

Abstract: An adjustable Danish tine for a farm implement includes a notched vertical run for attachment to a tool bar by a U clamp.

Abstract: An improved turbocharger system for a diesel engine includes a turbocharger driven by the exhaust gases of the engine. Air is compressed by the turbocharger prior to admission to the engine intake manifold. An auxiliary fuel tank filled with an alcohol and water mixture is pressurized by compressed air from a line connected to the turbocharger outlet. An auxiliary fuel line connects the fuel take to the intake manifold. So long as the auxiliary tank pressure is below a threshold pressure, a control valve maintains the auxiliary fuel line in closed condition. Upon exceeding the threshold pressure, the valve opens and the water and alcohol mixture is driven by an auxiliary pump and injected into the intake manifold. The outlet pressure of the turbocharger controls the initiation and quantity of fuel provided from the auxiliary fuel tank to the intake manifold.

Abstract: A minimum tillage rotary hoe includes a tool bar mounted transverse to the direction of field travel. Projecting rearwardly from the tool bar are a plurality of rotary hoe support arms each having a single, uniform diameter, multi-tined rotary hoe affixed to the end thereof. The rotary hoe members are staggered to define a forward row and a rear row of hoe members, each row defining generally a separate, single axis of rotation. The axes of the rows are separated by a distance less than the diameter of the rotary hoes but greater than about 0.8 the diameter of the rotary hoes. Separation is considered critical in order to render the hoes self-cleaning. Self-cleaning of field trash is effected by movement of adjacent hoes and more particularly the tines of adjacent hoes past one another to clean out the trash.

Abstract: A mechanism for wrapping a plastic cover sheet about a round bale of hay is incorporated in a round bale forming machine. The mechanism includes an arbor for receipt of a roll of wrapping material. The arbor is positioned in the bale forming machine forward of the bale forming mechanism. The wrapping material is fed from the roll and wraps about the formed round bale as the baling machine moves forward. After the wrapping material encircles the bale, it is cut. The cut end is overlapped on the wrapped bale and glued thereto. Various wrapping material feed and cut off mechanisms are disclosed.

Abstract: A drawbar for mounting two or more farm implement tool bars to a vehicle, such as a tractor, includes a single elongated crossbar with running gear. The crossbar extends transverse to the direction of vehicle travel and is hitched to the vehicle by a bracket and hitch assembly. Multiple farm implement tool bars are attached to the cross bar for field operation. The crossbar is hinged at its center and by proper adjustment of the bracket assembly may be folded to extend in the direction of vehicle travel. The drawbar is thereby converted to a narrow profile acceptable for road travel.

Abstract: A water brake dynamometer includes a water brake having a stator housing with a rotor disc mounted on a through shaft. Water from a reservoir is directed into the housing as the shaft and rotor are driven by an external engine. Means are provided to measure the torque transferred from the rotor to the stator housing. An adjustable, unitary valve mechanism controls the rate water is directed into the housing from the reservoir and removed from the housing for return to the reservoir. The valve mechanism includes a single stem having multiple valve members operated by a single hydraulic piston control.

Abstract: A water brake dynamometer includes a water brake having a stator housing with a rotor disc mounted on a through shaft. Water is pumped into the interior of the housing as the shaft and rotor are driven by an external engine. Momentum interaction transfers force between the rotor and stator housing. The planar surfaces of the opposing surfaces of the rotor housing are substantially identical as are those of the stator. A measuring device has been provided to measure the torque transferred from the rotor to the stator housing.

Abstract: A thermostatically responsive valve bypass mechanism includes a piston slidably mounted in a bypass channel through a valve member. The piston is normally spring biased to a first closed position. A heat transmissive probe is attached to the valve member and includes a series of thermostatic actuators mounted in opposed relation to the spring biased piston. The actuators expand in response to increased temperature and force the piston to an open position whereby fluid flow occurs through the bypass channel.

Abstract: A pressure responsive sensing device includes a housing defining a chamber. The chamber is filled with a non-compressible fluid and is closed at one end by a diaphragm. The diaphragm is retained in position by a cover plate. A stem connected to the outside of the cover plate projects through a bearing passage and has an outer end exposed to receive a force. A force on the end of the stem is transmitted via the plate and diaphragm against the fluid in the chamber. The pressure in the chamber, in turn, is transmitted ,o an electronic transducer sensing device through a constricted passage in the wall of the housing.

Abstract: An improved fertilizer knife includes a main knife-shaped blade which is inclined in a forward direction and which has a fertilizer discharge tube along its trailing edge for discharge of liquid fertilizer into the soil. A pair of wings attached to the main blade extend transversely. The wings lie in a plane generally parallel to the soil surface. The wings are swept back and include optional tip members.
