Title: Innovations of Charles E Beals
Introduction
Charles E Beals is a notable inventor based in Pekin, IL (US). He has made significant contributions to the field of hydraulic control systems, holding a total of 3 patents. His work primarily focuses on enhancing the efficiency and functionality of hydrostatic-mechanical transmissions.
Latest Patents
One of Beals' latest patents is a hydraulic control system for a hydrostatic-mechanical transmission. This innovative hydraulic circuit adjusts an infinitely variable drive ratio in response to the operator's speed and torque controls. It enables precise selection of the wheel torque of a vehicle while allowing for selective variation of ground speed by changing the drive ratio, all while the driving engine operates at a constant speed. The system utilizes control fluid from a pump driven by the engine to generate a displacement signal for the hydrostatic section of the transmission. This displacement signal is modulated to conform output torque with the operator's selected torque signal. Additionally, the system includes sensing means for engine underspeed and overspeed, ensuring optimal performance under varying conditions.
Another significant patent involves valving for a dual radial piston motor. This drive apparatus is designed for a rotary output member of a vehicle, featuring a pair of orbiting members with outwardly-projecting teeth that engage with inwardly-projecting teeth of the output member. Hydraulically-actuated piston and cylinder means facilitate the orbiting of these members, which in turn rotates the rotary output member through a rotary valving element.
