  • Patent number: 9618104
    Abstract: An anti-lash nut assembly for installation on a threaded rod and including a lead nut, a collar, and a spring positioned between the lead nut and the collar. The lead nut has a set of tabs extending radially outward from a rear end of the body. The collar has a set of clearance slots on an inside surface. The set of clearance slots are configured for sliding of the set of tabs through the clearance slots in the rear direction. The collar has a set of ramps on an inside surface. Each of the set of ramps is configured for engagement with each of the set of tabs to prohibit axial movement of the collar in the rear direction.
    Type: Grant

  • Patent number: 8256197
    Abstract: A method and apparatus for enabling reverse mow condition in a tractor comprises a switch assembly having an ignition switch that is rotatable through a plurality of positions, a housing for supporting the ignition switch, and an actuator movably located in the housing. The enabling of a reverse mow condition is achieved by displacing the actuator from a rest position to two separate and distinct positions.

  • Patent number: 7488914
    Abstract: A switch is disclosed having a switch housing defining a housing interior and an access opening that extends through a wall of the housing to the housing exterior. An actuator assembly including a shaft constrained by said housing moves along a path from a normal position to an actuated position as well as a momentary position. The shaft has an actuating portion which extends outwardly from the housing interior through the access opening. A shaft body inside the housing including a generally planar contact support that supports a number of switch contacts. A housing base positions a number of terminals having conductive surfaces for biased engagement with selected switch contacts to form an electrical path between terminals when the actuator assembly is in one of either the normal, actuated or momentary positions.
