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 including a valve for disabling the supply of air to one side of a pneumatic piston and cylinder device (15) and a push-rod (51) operative connected to the valve and extending along the inside of the air supply conduit
The push rod normally contacts the displaceable end (43) of the cylinder when the displaceable end is in its safe position so as to operate the valve to allow the supply of air to the pneumatic chamber. The push-rod is movable, when the displaceable end of the cylinder is displaced from its safe position, to operate the valve so as to disable the supply of air under pressure to the cylinder on the aforesaid side of the piston.
