Title: Inventor Douglass W Crawford: Innovating Well Flow Control Technology

Introduction

Douglass W Crawford is an accomplished inventor located in Crowley, LA, with a noteworthy track record of two patents. His contributions to the field of well flow control technologies demonstrate significant advancements in efficiency and functionality.

Latest Patents

Among his latest inventions is the "Kickover tool for placing and removing well flow control devices." This innovative tool features an orienting section with angularly spaced dogs designed to collaborate with a sleeve in a side pocket mandrel. This mechanism facilitates the orientation of the tool and triggers the longitudinal movement of a control rod. As the rod moves, it activates a kickover arm, allowing for the extension of guides that work in tandem with ramps within the side pocket mandrel. This ultimately ensures that the valve coupled to the kickover arm is securely inserted through a seat and latched in place in the mandrel. The design also includes a clutch mechanism to prevent any premature actuation of the tool.

Another significant patent from Crawford is related to the "Side pocket mandrel." This invention comprises a tubular main body featuring an internal bore, with a seating section welded at one end. The seating section has a main bore and an inclined seating bore that opens to the exterior. It incorporates a polished section and a latch shoulder, along with a gas flow opening connecting the seating bore to the main bore. By aligning the tubular member with an orienting sleeve and utilizing strong transverse welds, this mandrel achieves a compact and high-strength assembly.
