Abstract
A tool which is designed primarily to be used by truckers, which takes the form of a housing, one end of which terminates in a graspable handle and the other end of which terminates in an operating head. Within the graspable handle there is located an air pressure gauge. Within the operating head, there is located a valve assembly. The valve assembly is to be connectable to a source of pressurized air which is to be conducted through an air passage assembly within the housing to an air pressure gauge. The air pressure operates an inflation valve of the air pressure gauge and visually displays a value corresponding to the amount of air pressure. The operating head includes a groove arrangement permitting mounting thereon of an accessory tool. The valve assembly is movable relative to the operating head.
