Abstract
An ergonomic, pneumatically-powered hand tool for installing hose clamps comprises an elongated barrel projecting from a pistol grip housing which pivotally mounts a locking jaw assembly for securely grasping clamps to be installed. A trigger-controlled valve assembly coupled to a source of high pressure air powers the tool. The jaw assembly comprises a pair of identical jaws pivotally coupled together to define a clamp-receptive mouth. Each jaw comprises a plurality of serially interconnected channels defined along the gripping end of each jaw, adapting the mouth to both accommodate clamps of varying sizes and to restrain clamps as they are compressed during installation. The gripping ends project outwardly beyond the barrel, and are spaced apart from the opposing terminal ends. An integral bearing plate is defined between the terminal end and the gripping end. The terminal ends of the jaws are resiliently biased together by a spring. Each terminal end comprises a sliding surface having a roller for deflecting an air-driven plunger between the jaws. When the tool is activated by compression of the trigger, pressurized air drives the plunger between the jaws, so that the terminal e…
