Latest Patents

Tyner’s listed patent, “Core Cutting Rock Bit,” describes a roller cone drill bit that leaves a substantial formation core uncut. The core measures 10% to 25% of the bit’s gage diameter. The design retains normal-sized bearings, cone shell thickness, and cutter protrusion, allowing the bit to operate with standard drilling weights and rotational speeds while increasing the drilling rate. For abrasive formations, ultra-hard cutting teeth at the cone apex help maintain the core diameter.

Career Highlights

Tyner’s patent reflects an approach to drill-bit design that balances formation cutting with the durability and operating requirements of conventional equipment. His listed company affiliation is Smith International, Inc.

Collaborations

Tyner’s listed coworkers include fellow inventors Gary Ray Portwood and Charles R. Muren.

Conclusion

Gilbert S. Tyner’s patented core-cutting rock bit combines a controlled formation core with standard drilling parameters, illustrating his contribution to drilling technology.
