Title: Allyn M Aldrich: Innovator in Torque Sensing and Propeller Control

Introduction

Allyn M Aldrich is a notable inventor based in Rockford, IL (US), recognized for his contributions to torque sensing and propeller pitch control technologies. With a total of 7 patents to his name, Aldrich has made significant advancements in engineering that enhance the functionality and reliability of various mechanical systems.

Latest Patents

One of Aldrich's latest inventions is the "Simply Supported Secondary Shafting System Torque Sensor." This innovative torque sensor addresses the limitations of traditional cantilevered screw and nut arrangements. The design features a long gear that receives torque input from a primary shafting system, which is simply supported between bearings to eliminate cantilevered support. Additionally, a threaded shaft receives torque input and has a traveling gear mounted for axial movement, allowing for effective torque transmission.

Another significant patent is the "No-Back Apparatus for Propeller Pitch Control." This mechanism includes a brake that resists motion of a first member and a uni-directional coupling that connects a pitch control prime mover to an adjustable pitch propeller. This design allows for limited movement during back driving while preventing brake release or slipping, thus reducing wear on brake plates during normal operation.
