Latest Patents

One of his latest patents is for a "Retainer for Rotary Cone Drill Bit." This invention describes systems and structures for a rotary cone drill bit that features a body and rolling cone cutters. The rolling cone cutters are coupled to the body through a bearing retention interface that includes ball bearings in a captured channel. These ball bearings are inserted through an opening that is later filled with a retainer pin, which has an engagement feature ensuring alignment with the captured channel and the ball bearings. This design aims to reduce wear within the rotary cone drill bit.

Another significant patent is for a "Bearing Clearance Arrangement in a Tricone Bit." This invention involves a leg assembly of a tricone bit that includes a cone and a leg fitting inside the cone. The leg features an axis that defines the axial center of rotation of the cone, along with multiple raceways for bearings. The design specifies that the first row of bearings supports most of the radial load applied to the tricone bit, optimizing performance and durability.
