Title: A HAND-OPERATED RIVET SETTING TOOL
Abstract:
A hand-operated rivet setting tool having an upper handle (201), a lower handle (202), and a housing connected to a first end of the lower handle (202). The housing houses a pump assembly and a flexible reservoir that are connected to one another. The tool further Includes a front assembly for setting a rivet and having a nose tube (209) connected to a hydraulic cylinder (206) of the pump assembly, and a lever assembly (220). The lever assembly (220) and at least one of the handles (201, 202) are operationally connected to the pump assembly. The pump assembly advances the hydraulic cylinder (206) with the nose tube (209) to set the rivet when the sever of the lever assembly (220) is in a first position. The pump assembly opens a passage for oil to return into the flexible reservoir and the hydraulic cylinder (208) with the nose tube (209) to retrieve toward the housing when the lever of the lever assembly (220) is in a second position.
