Title: Innovations of William F Abraham

Introduction

William F Abraham is an accomplished inventor based in Lancaster, NY (US). He holds a total of 4 patents that showcase his expertise in the field of linear actuators and drive mechanisms. His innovative designs have contributed significantly to advancements in automation and control systems.

Latest Patents

One of his notable patents is the "Anti-lockup drive mechanism for a position controlled linear actuator." This invention features a linear actuator equipped with an electric motor that rotates a drive pinion gear. The drive pinion is in mesh with an intermediate gearing arrangement, which in turn meshes with a main drive gear. This setup allows for the rotation of a drive screw, leading to the longitudinal advancement of a drive nut. The design includes a lost motion mechanism that prevents lockup of the actuator by allowing the drive pinion to complete a revolution before imparting torque to the drive screw.

Another significant patent is the "Position controlled linear actuator." This actuator includes an electric drive motor connected to a drive screw through a gear train. The rotation of the drive screw causes the drive nut to move axially, imparting motion to an extension member. The design incorporates limit switches that disengage power to the motor when the extension member reaches its stroke limits. Additionally, a thermal sensing element interrupts power to the motor if the windings heat up beyond a predetermined temperature, ensuring safety and reliability.
