  • Patent number: 5489113
    Abstract: A tie rod assembly for a steering wheel structure for an agricultural vehicle such as a row crop applicator uses hydraulic cylinders to set the track width of the vehicle. The track width may be modulated between a minimum and a maximum track setting and modified until a desired track width is achieved while the vehicle is in motion and negotiating a turn without affecting toe-in settings. Toe-in settings are maintained by a closed loop series hydraulic system which further has the capability to reinitialize any toe-in setting to a preset condition in the event any hydraulic cylinder experiences cylinder drift.

  • Patent number: 5485760
    Abstract: A ball nut and screw assembly with a screw having exterior helical ball carrying groove portions separated by land portions and a co-axial nut having complemental, helical interior ball carrying groove portions separated by land portions with the same lead as said screw groove and land portions has, an end attachment for the nut with a reduced diameter sleeve extending axially therefrom. The sleeve has helical exterior thread portions, of the same lead as the nut groove portions, which are of a matching configuration and are threaded into one end of the nut. The sleeve has an interior diameter which receives and passes the screw without interacting with the screw. A recirculating train of load bearing balls is accommodated within nut and screw groove portions which are axially spaced from the sleeve.

  • Patent number: 5447083
    Abstract: A linear link is provided which comprises an inner and an outer telescopically movable pair of members in which a catch arrangement is operative between formations on the two members to selectively lock them in one particular telescopic position, or to allow them to move telescopically, thereby providing for a limited and optionally adjustable degree of lost motion between the ends of the linear link. A co-axial solenoid carried by the outer member controls the catch arrangement to provide selectively for rendering it operative or not according to whether or not the solenoid is energised. The linear link may be lockable in either its maximum or minimum degree of telescopic extension.

  • Patent number: 5429014
    Abstract: An adjustable, pre-set, threaded and torqued pedal rod has a shaft part and a head part which are selectively adjusted and assembled with the use of screw threads to a pre-selected longitudinal mean dimension and then securely crimped to lock the parts together so that the two parts cannot be separated without total destruction. Screw threads of different size are disposed on two separate tiers to afford torque locking.

  • Patent number: 5394572
    Abstract: A bath drain outlet control having an actuator, a plunger valve for engaging a valve seat of a bath drain outlet, a linkage between the actuator and the plunger valve, including a one-way slip clutch enabling the linkage to be contractably adjustable, and a slip clutch deactuator movable into operative relationship with the one-way slip clutch to temporarily allow expansion adjustment of said linkage. The one-way slip clutch has an elongated rod forming part of the linkage, a retaining ring having a plurality of sloped spring fingers around the rod, having an inherent bias toward the rod, and having rod engaging ends normally allowing rod movement in a linkage-contracting direction therethrough but preventing reverse rod movement therethrough in a linkage-extending direction. A compressed O-ring engages the sloped spring fingers to add bias supplementing the inherent finger bias toward said rod and equalizing the bias of the spring fingers against the rod.

  • Patent number: 5392663
    Abstract: A machine element support comprised of a plurality of axially extensible and contractible servostruts which are individually adjustable and collectively controllable. The struts comprise an outer tubular member and a slidably, interfitted, elongated, inner member. The powered servostruts are movably connected to an machine element such as a spindle head by one of the members on one end and to a rigid machine tool frame by the other of the members on the other end. Linear position sensors mounted on the servostruts serve to precisely measure strut extension and retraction for feedback control purposes. A preferred servostrut configuration is a hexapodal array, in which two servostruts are mounted side by side in each of the three well-known orthogonal axes of machine tool practice, providing six-axis movement and positioning of the tool head or workstation relative to the workpiece.

  • Patent number: 5349902
    Abstract: A shutheight adjustment mechanism of a press including a male threaded member threadedly engaged to a female threaded member with a clearance space therebetween is flooded with a liquid to reduce undamped free movement between the threaded members. Liquid injected in the clearance space causes a squeeze-film to be created, capable of supporting high impulse working loads. Seals define the clearance space to assure that the entire clearance space is filled with liquid. In one embodiment, the shutheight adjustment mechanism is included in the press slide.

  • Patent number: 5282644
    Abstract: A variable tie-rod assembly for a steering wheel structure of a row crop applicator. The tie-rod assembly can be adjusted and secured in any position between a minimum and maximum track setting. Thus, a selectively variable track width is provided. Toe-in settings are maintained by implementing a dual-cam arrangement with a locking pin to maintain the steering structure in a forward direction during track width adjustment procedures. The track width setting can be adjusted without the operator ever having to leave the cab of the row crop applicator, wherein the track width can be visually ascertained by observing indicia on the telescoping wheel structure.
