  • Patent number: 5274987
    Abstract: A manual powered lawn mower comprises a pair of large diameter drive wheels on an axle, two clutch and roller bearing mechanisms on the axle coupling the drive wheels thereto, a gear mechanism coupled to the axle for translating rotation of the drive wheels to rotation of a gear around a vertical axis, and a rotary type blade which is coupled to the gear mechanism via a vertical axle and another clutch and roller bearing mechanism. When the lawn mower is pushed forward, the clutch and roller bearing mechanisms on the wheel axle causes the axle to drive the gear mechanism, which in turn drives the vertical axle and the blade. When a drive wheel is not turning the axle faster than the speed that the axle is turning, that drive wheel is decoupled by the clutch and roller bearing mechanism and no longer adds either power or drag to the system. With clutch and roller bearing mechanisms on each wheel, a "differential" is provided which permits maneuverability without adversely affecting blade speed.

  • Patent number: 3951465
    Abstract: A motor vehicle wheel engages a gear which drives a multistage cam which actuates a system of hydraulic valves and pistons. A pressure-sensitive spool valve detects when the hydraulic pressure in the brake system exceeds the value which causes the wheel to enter the skid mode. The hydraulic pressure from the brake system passes through the pressure-sensitive valve to the system of hydraulic valves and pistons operated by the cam. The outlet of the hydraulic valve and piston system goes to the brake cylinder in the wheel. During the skid mode, a valve in the hydraulic valve and piston system closes and a cam action on one of the pistons in the system causes a pumping pressure to be applied to the brake cylinder. This anti-skid device further includes two fail-safe features to protect against system failure.
