    Abstract: A manually operable control device, such as a joystick, includes a plurality of actuators for operating hydraulic valves of a machine. A handle has a sphere received within a cavity formed between a pair of seat portions which are moveable with respect to each other. The handle produces movement of at least one of the plurality of actuators when the sphere is pivoted within the cavity. An electromagnetic coil generates a magnetic field that causes the seat portions to be attracted toward each other which increases friction between the sphere and the seat. A control circuit applies electric current to the electromagnetic coil whenever the machine is turned on and disconnects the electric current when the machine is turned off. The friction between the sphere and the seat holds the control device in an operating position set by the machine operator and springs return the control device to a neutral position when the machine is turned off.

  • Patent number: 5809755
    Abstract: A zero turning radius power lawn mower for operation by a standing occupant includes first and second independently driven and controlled rear drive wheels mounted on separate drive axles. A riding platform for supporting the standing occupant or operator is located between the first and second rear drive wheels. The rear drive wheels are independently driveable in both the forward and reverse directions at variable speeds so as to allow for substantially zero radius turning of the mower about a central turning point. The riding platform is positioned near this turning point or axis so that the standing occupant remains substantially unaffected by centrifugal force created during approximate zero radius turning of the mower thereby allowing the mower to take such turns at higher speeds. The low center of gravity created by the position of the riding platform for the standing operator also results in the mower having improved traction and being less likely to pop "wheelies" upon acceleration.

Reverse motion is obtained when the clutch engages the actuator and upper lever, after which it releases the actuator and a second drive lug engages the lower lever to return it to its starting position.

  • Patent number: 5197347
    Abstract: A control system including interfaced hand and foot control assemblies for independently conditioning an off-highway implement by selectively positioning a regulator thereof relative a neutral position. The hand and foot control assemblies utilize a common force transfer mechanism in the form of a push/pull cable for moving and positioning the regulator. The foot control assembly includes a self-centered foot pedal and linkages for arranging the push/pull cable relative to the regulator in a manner inhibiting binding forces from being imparted to the cable. The hand control assembly requires independent movement of a control lever in two different planes to shift the hand control assembly from a neutral condition. Moreover, the hand control assembly is isolated from spring forces acting to self center the foot pedal and thus requires low operator efforts to adjust the position of the regulator. The control system of the present invention further includes a mechanism for governing operation of the regulator.

  • Patent number: 5180050
    Abstract: A switch actuator mounted in a housing for axial and rotary movement operates a rotary switch on the actuator axis through an axial lost motion connection. A pushbutton switch offset from the axis is engaged by a semi-circular plate radially extending from the actuator and is actuated upon axial movement of the actuator for any rotary position of the actuator. Optionally, the plate has apertures which register with the pushbutton switch at selected actuator rotary positions to disable pushbutton operation at the selected positions. The actuator is made of light conducting transparent plastic to illuminate an indicator on the switch knob from a bulb within the housing. A flexible detent finger integrally molded into the housing engages the plate during its axial movement to impart tactile feel.

  • Patent number: 5142934
    Abstract: A control device on a chain saw, for example, a gas control, consisting of a finger grip (12) and a lever (11) (snapped together) to which the cable and the sheath of a Bowden cable (10) are attached, respectively. The other end of the sheath is fastened to the base of a carburetor compartment. When the grip and the lever move upwards, the rear end (28) of the lever hits a fulcrum (20) in the handle. The grip can continue upwards due to a guide point between the lever and the grip and, thus, the wire is moved in relation to the sheath so that a gas lever (13) of the carburetor is tuned. The sheath, consisting of a spirally wound steel wire, is tightly wound, but has also a short length (31) being sparsely wound as a pressure spring and provides an overload protection preventing the cable from breaking.
