Abstract: Adjustable pliers for a constant tension hose clamp include a pair of arms pivotally connected together at intermediate portions of the arms. Each arm has a handle portion and a gripping portion, and the gripping portions have opposed ends that are spaced apart a predetermined distance. Each end has a grasping element, with each grasping element adapted to hold one actuating member of the hose clamp. This enables the hose clamp to be held by the grasping elements between the gripping portions to enlarge the diameter of the hose clamp by pressing the handle portions together. One of the arms has two separate sections, a gripper section and a handle section. These sections are rigidly connected together by an adjustable rod mechanism that enables the two sections to be moved relative to each other to change the angular relationship between the two sections by adjustment of the rod mechanism.

Abstract: A pliers for a hose includes a pair of arms pivotally connected together at intermediate portions of the arms. Each arm has a handle section and an end section opposite the handle section, and a "floating" gripper attached to the end section of each arm. Each gripper has an internal surface which substantially conforms to the configuration of a portion of the external surface of the hose being engaged by the grippers upon grasping the hose with the pliers.

Abstract: Disclosed is a tool for use with brake pistons and the like having a generally cylindrical body with a working face at one end of the body member which has an area and configuration corresponding to the face of the piston. The piston has one or more shall depressions therein which are normally unsuitable for use with conventional tools. The characterizing feature of the tool is a rim extending outwardly from the working face and surrounding it. When the tool is placed over the face of the piston, the rim grips the perimeter of the piston. A pin extending outwardly from the working surface is aligned with the deepest depression when the tool is placed over the face of the piston. The rim and pin coact to rotate the piston upon rotation of the tool.
