Title: C Warren Duncan: Innovator in Core Drilling and Manhole Cover Technologies

Introduction

C Warren Duncan is a notable inventor based in Santa Ana, CA, with a remarkable portfolio of 10 patents. His innovative contributions primarily focus on core drilling systems and manhole cover removal technologies. Duncan's inventions have significantly improved operational efficiency and safety in various applications.

Latest Patents

One of Duncan's latest patents is a core drilling system with a torque shaft. This system features a torque tube equipped with a groove or keyway that accommodates a rotating wheel or key. This design prevents the transmission box and motor from rotating during drilling operations, allowing the operator to concentrate on the substrate being cut without the need for a stabilizing arm. Additionally, a torque tube stabilizing leg assembly can be secured to the free distal end of the torque tube for enhanced stability.

Another significant invention is the manhole cover frame removal saw. This apparatus includes a ring-shaped base with a circular track and a saw mounting framework positioned atop the base. The saw mounting framework can rotate around aligned vertical axes, and a saw mounting arm can be raised, lowered, and locked in place. The saw carriage mounted on the arm allows for reciprocal movement, and a single saw motor can be immobilized at various angles. This design enables the use of separate horizontal-cut and vertical-cut saw blades, which can be alternately attached to the saw blade rotor.
