Abstract: A fastener driving tool for driving remotely located fasteners through preformed openings in a structure. The tool (10) comprises a housing (12) having a pneumatic-hydraulic intensifier (14) mounted thereon and a remotely located second hydraulic cylinder assembly (20) attached to the housing (12) by means of an extension tube (110). Pressurized air is provided to the tool (10) through a cartridge regulator (36) that is controlled by a trigger assembly (41). A pneumatic piston (72), connected to a first hydraulic piston (76) by a piston rod (80), moves from a first position located away from a nose portion (66) to a second position located toward a nose portion (66). The pressurizing valve (56) admits air to the pneumatic piston (72) to cause the first hydraulic piston (76) to move to the second position, thereby pressurizing hydraulic fluid (92) and causing the second hydraulic piston (102) to extend from the second cylinder housing (104).

Abstract: A lattice template for locating aircraft structure and pilot holes behind flat or contoured surface panel structures. The lattice structure of template strips positioned by bridge structures or flexible cables enables adjustment of template strips within the lattice template thereby enabling coordination with its respective structural element to accommodate tolerances of assembly.

Abstract: A surface of a wedge acts as a stop to limit travel of a spindle on an automatic riveting machine. A drive mechanism moves the wedge back and forth to vary the heighth of the wedge, and the same mechanism simultaneously moves a rod back and forth to act on a transducer, and transmit an electrical signal to give a digital readout of the change in heighth of the wedge.
