Title: Celebrating the Innovations of Donald S Christopher from Willowick, OH
Introduction: Donald S Christopher is an inventive mind hailing from Willowick, OH, known for his contributions to engineering through innovative designs. With a remarkable portfolio of two patents, he has carved a niche in the industry by creating effective solutions to everyday challenges.
Latest Patents: Among his latest inventions are the "Reversing Ratchet Door Closer" and the "Weight-Sensor Calibration for Gravimetric Coal Feeder."
The **Reversing Ratchet Door Closer** features a unique lever assembly designed to drive a bolt or threaded element in both clockwise and counterclockwise directions. The assembly comprises a housing with a coaxial bore that accommodates a drive head, which is equipped with radial external ratchet teeth. A double pawl, pivotally mounted within the housing, engages the ratchet teeth in a versatile manner that allows for forward and reverse operations. The handle, grasped by the operator, includes a mechanism that biases the pawl to a neutral position, ensuring effective handling during operation.
The **Weight-Sensor Calibration for Gravimetric Coal Feeder** is another noteworthy invention. This device employs a weight-sensing control mechanism that accurately feeds particulate materials, like coal, at a controlled rate. The mechanism continuously monitors the material weight within a designated zone using load cells that generate voltage signals representative of the sensed weight. The test load can be positioned either independently of the weight-sensing mechanism or transferred to it for calibration, with an operator outside the conveyor unit facilitating the process through a transverse shaft with eccentric hubs.
