ABSTRACT:
Improved forms of pneumatic tools of the type shown in U.S. Pat. Nos. 4,040,554, 4,098,171 and 4,122,904 are provided for driving nail-like fasteners into a workpiece. The tool may be used for attaching small articles such as washers or name tags to the workpiece, in which event the tool may be combined with a device for holding the article and positioning it so that it will be engaged and penetrated by a fastener as the latter is discharged by the tool into a workpiece. The tools are provided with novel handle means designed to make the tool convenient and safe to use where the operator cannot or should not engage or be close to the workpiece. A further novel inventive feature is an improved form of poppet valve for causing operation of the tool.
