Abstract: An extracting tool (14 ) for extracting a keying block (12) having keying pins (13) extending outwardly therefrom from the terminal pins (11) of a backplane (10) of an interconnection system. A keying pin seizing mechanism is retained on a mounting card (27) dimensioned to fit between the rails 17 and 18 of a guide frame normally holding a circuit board. The seizing mechanism comprises a pair of adjacent vise blocks (15, 16) having aligned holes (19) to correspond to the locations of the keying pins (13). When the card (27) is fully inserted in the guide frame, the keying pins (13) of the keying block (12) pass through the aligned holes (19) of both vise blocks (15, 16). The latter blocks have opposing parallel faces (20, 21) lying at an angle to the axes of the keying pins (13).

Abstract: A tool with a pair of longitudinally translatable components, includes a base with a lip to engage the underside of a boot covering a spark plug of an internal combustion engine. The other component, a slideable tongue, engages the engine head to provide a controlled reaction force against the underside of the boot to force it off the spark plug. The base of the tool may be fitted against the boot for aligning the tool to direct the reaction force in a direction substantially parallel to the longitudinal axis of the spark plug. The tool is activated after alignment by manually compressing a handle connected to the tongue to move toward a finger grip rigidly secured to the base. The tongue preferably is connected to the handle by an actuating rod guided by a sleeve mounted on the base.

Abstract: A power operated tool (20) functions to cut and collect a multitude of precious metal contacts (11,11) from wire spring relays (10). The tool (20) includes a pair of jaws (31,32) that in the open position fit over several rows of contacts (11,11). When the tool (20) is energized, the jaws (31,32) are snapped shut thereby severing the contacts (11,11) from the relays (28). The jaws (31,32) in the closed engaged position define a closed chamber (41) having a port (44) for attachment to a vacuum source for sucking the severed contacts (11,11) into a collection vessel. The jaws (31,32) reopen following collection and the tool (20) is ready to cut the next set of spring contacts (11,11).
