Abstract: An electronically operated portable nail driving gun is disclosed. Nails are driven into a workpiece by a driver blade which is actuated by a solenoid powered by a source of alternating current. Each actuation of the device produces two successive driving strokes delivered to a nail. The tool is also provideed with means for preventing more than one nail being driven during each actuation of the tool. A preferred embodiment in which the tool is double insulated is also disclosed as are control circuits which permit operation at either 110 V. or 220 V.

Abstract: An electronically operated portable fastener driving tool is disclosed. Fasteners are driven into a workpiece by a driver blade which is actuated by a solenoid powered by a source of alternating current. Each actuation of the device produces two driving strokes delivered to a fastener. The tool is also provided with means for preventing more than one fastener from being driven during each actuation of the tool. A preferred embodiment in which the device is double insulated is disclosed. Control circuits which permit operation at either 110 V. or 220 V. are also disclosed.

Abstract: An electronically operated portable fastener driving tool is disclosed. Fasteners are driven into a workpiece by a driver blade which is actuated by a solenoid powered by a source of alternating current. Each actuation of the device produces a predetermined plurality of driving strokes being delivered to a fastener. The tool is also provided with means for preventing more than one fastener from being driven during each actuation of the tool.

Abstract: A collapsible rack is disclosed which comprises a plurality of partition members which are pivotally joined together at their bases with linking members to form an expandable lazy tong structure. A plurality of guide means which are each secured to and integral with the linking members are provided for guiding stacks of sheets placed in the rack. The guide means define slanted guide surfaces which extend between the bases of adjacent partition members. The guide surfaces all have a substantially common orientation on the linking members. The guide means also serve the function of improving the rigidity of the structure, defining back-up surfaces that insure the proper support of the sheets and fan the sheets into oblique relationship with each other enabling convenient removal of the sheets.
