Abstract: In a fastener installation tool, a hydraulically actuated head piston (22) is actuated on its power stroke to instal a fastener, and has return means for returning the head piston independently of the hydraulic arrangement. The tool also has a pneumatic hydraulic intensifier (12, 13) for providing the hydraulic actuation above-mentioned. The hydraulic intensifier has a hydraulic cylinder and a piston rod reciprocable in the hydraulic cylinder, and is provided with a seal (54) for sealing between the end of the piston rod and the wall (39) of the cylinder as the piston rod is driven into the cylinder. The seal is separated from the piston rod and is supported on the end face of the piston rod so as to allow radial movement of the end of the piston rod with respect to the seal. The seal may be provided by an assembly which comprises a substantially rigid support member (57) and an annular flexible sealing member (54). The latter contacts both the end face of the piston rod and the annular sealing member. The annular sealing member makes sealing contact with both the support member and the wall of the cylinder.

Abstract: A fastener installation tool installs fasteners of the type in which a part of the fastener is broken off during the installation process. The tool has collection means for collecting broken off fastener parts during operation of the tool. The collection means (34) is removably connectable to the tool. A safety device in the tool is responsive to the collection means being connected to the tool or being not connected to the tool. The safety device (64, 68, 72) allows further operation of the tool only when the collection means is connected to the tool.

Abstract: In a fastener installation tool which is pneumatically powered to instal a blind rivet or bolt by a relative pulling action, a pneumatic/hydraulic intensifier (12, 13) is included to actuate hydraulically the pulling stroke of a head piston (22) which provides the relative pulling action. It is desirable to design such tools so that they have increased levels of safety for the persons using and operating them. In such a tool, there is provided a safety device comprising: valve means for disabling the supply of air to one side of a pneumatic piston (15) and cylinder device and a push-rod (51) operative connected to the valve means and extending along the inside of the air supply conduit; the push-rod normally contacting the displaceable end (43) of the cylinder when the displaceable end is in its safe position so as to operate the valve means to allow the supply of air to the pneumatic chamber, and the push-rod being movable, when the displaceable end of the cylinder is displaced from its safe position, to operate the valve means so as to disable the supply of air under pressure to the cylinder on the aforesaid side of the piston.

Abstract: In a fastener installation tool, return of a head piston (22) is effected by the application of air under pressure to the rear side of the piston. The end of the head cylinder body on the rear side of the piston is provided with a removable end member (34) which is displaceable away from a position in which it is safely secured to the head cylinder body (14). Also, the tool further includes a safety device in the form of air vent means (64) which, if the end member is displaced beyond a predetermined amount, opens to vent air under pressure from the head cylinder body on the rear side of the head piston (22), thereby preventing the return of the head piston and thus the further operation of the tool.
