20140339333 | Sprinkler With Internal Compartments - A sprinkler includes a compartment that surrounds its riser portion in an offset or asymmetrical configuration. More specifically, the distance of the compartments walls from those of the riser vary (i.e., increase or decrease) at different locations surrounding the riser. Put another way, the riser is closer to one side of the compartment than other sides of the compartment. This non-concentric configuration allows larger components to fit inside the compartment than would otherwise fit if the riser was symmetrically surrounded by the compartment. | 11-20-2014 |
20140338300 | Power Vehicle with Adjustable Velocity Profiles - Embodiments of the present invention relate to powered vehicles (e.g., lawn mowers) and, more particularly, to a control system for use with such a vehicle. In one embodiment, the vehicle includes a power source such as an internal combustion engine and one or more drive control levers incrementally movable between a neutral position and a maximum velocity position. The system may also include a velocity profile control system having an adjustment member that permits altering a ratio between control lever movement and velocity of an associated drive member or wheel. Thus, the system may alter a maximum potential velocity of the vehicle while the drive control lever(s) are positioned in the maximum velocity position without varying an output level of the power source. | 11-20-2014 |
20140332307 | UTILITY VEHICLE WITH A CONTINUOUSLY VARIABLE TRANSMISSION HAVING A SYSTEM FOR SELECTIVELY ESTABLISHING A FIXED MAXIMUM TRANSMISSION RATIO - A continuously variable transmission for a vehicle comprises a primary pulley, a secondary pulley, and a belt entrained around both pulleys in an opposite manner between the fixed and movable sheaves thereof. One pulley carries a selectively deployable stop that may be placed into position to mechanically limit the range of motion between the fixed and movable sheaves. This establishes an actual maximum transmission ratio that is larger than the nominal minimum transmission ratio but smaller than the nominal maximum transmission ratio achievable by the transmission during normal operation thereof. When such a transmission is used on a utility vehicle attached to a substance dispensing applicator operatively driven by the vehicle's engine, the application rate stays substantially constant despite changes in engine speed when the user keeps the transmission upshifted to the actual maximum transmission ratio set by the position of the deployed stop. | 11-13-2014 |
20140283492 | HYBRID ELECTRIC TURF MOWER WITH POWER SHED AND POWER BOOST - A turf mower has one or more electrically powered cutting units and a traction drive system that is operatively powered by an internal combustion engine. A motor generator is also powered by the engine and is operatively connected to the engine and the traction drive system. A battery pack stores electrical energy and is charged by the motor generator during normal mowing on flat ground. When mowing on hillsides with increased mechanical power requirements above that supplied by the horsepower of the engine, a control system first removes the load imposed by the cutting units by supplying the electrical energy to the cutting units from the battery pack instead of the motor generator. If that is insufficient, the control system then uses energy from the battery pack to power the motor generator as a motor to supply additional mechanical power for use by the traction drive system. | 09-25-2014 |
