Latest Patents

One of Orrin's latest patents is titled "Attitude control for implement." This invention involves a vehicle that includes a stick cylinder, which is movable to change the attitude of a stick relative to a boom. Additionally, an implement cylinder is included to change the inclination of an implement relative to the stick. The hydraulic circuit means are designed to connect the cylinders serially, allowing for coordinated movement. As the stick cylinder moves the stick in one direction, the discharge of fluid from the stick cylinder actuates the implement cylinder, maintaining the implement's attitude relative to the ground. A flow divider is interposed between the cylinders to provide the desired degree of actuation. Furthermore, a dual pressure-responsive bypass valve is incorporated to manage pressure relief and discharge paths for the implement cylinder.

Another significant patent is the "Apparatus for forcibly engaging machine assemblies." This locking apparatus features first and second assemblies, each containing an inclined plane. The inclined planes contact one another at a locking position, effectively fixing the first assembly to the second. The design includes mechanisms to urge one inclined plane into the other, ensuring that they maintain contact during movement and compensating for wear over time.
