Title: Chad N. Zigler and the Automatic Adjuster for a Brake Piston

Introduction

Chad N. Zigler is an inventor associated with Mishawaka, Indiana, and AlliedSignal Inc. His listed invention, the “Automatic adjuster for brake piston,” addresses piston clearance in a hydraulic brake actuator. Zigler is credited with 1 patent.

Latest Patents

Zigler’s listed patent describes a mechanical adjustment arrangement for a hydraulic brake actuator. The actuator’s piston moves within a cylindrical bushing between a retracted position, which maintains clearance from the brake mechanism, and an extended position, where hydraulic pressure moves it to engage and operate the brake.

A return spring brings the piston back when hydraulic pressure is relieved. To compensate for excessive piston travel, an expandable sleeve surrounds a cantilevered pin fitted with a split expander ring. As the piston travels too far, the sleeve moves along the ring and establishes a new retracted position. The design also allows the sleeve and split ring to be removed and replaced during brake maintenance.

Career Highlights

The available information connects Zigler’s patent work with AlliedSignal Inc. His listed contribution focuses on maintaining appropriate piston clearance and supporting straightforward replacement of adjustment components during servicing.

Collaborations

Richard B. Jankowski is identified as Zigler’s coworker. The provided information does not specify further details about their collaboration or their respective roles in developing the brake-piston adjuster.

Conclusion

Chad N. Zigler’s listed patent presents a practical approach to automatic brake-piston clearance adjustment, combining compensation for piston travel with replaceable components for maintenance.
