Abstract: A manually held hydraulically and pneumatically powered swaging tool for swaging a collar (35) onto a grooved or threaded bolt (36) includes jaws (39) having internal grooves (40) which match the groove (20) on the bolt. The jaws (39) are openable to receive the projecting portion of the bolt (36) and are closable to engage the bolt. An anvil (26) outside the jaws is axially movable by hydraulic means forwards over the jaws to lock them into engagement with the bolt, and then to force the anvil over the collar (35) to swage it to the bolt. The tool includes a detection rod (40) for detecting when the bolt (36) has been fully inserted into the open jaw (39). Thereby to initiate closure of the jaws by pneumatic means. Also, initial forwards movement of the anvil (26) is arranged to move the jaws axially forwards by an appropriate small distance, if this is necessary to axially align the grooves (40) on the jaws correctly in relation to the groove (20) on the bolt to enable closure of the jaws.

Abstract: A shuttle (11) for feeding tubular rivets (12), which are of relatively short axial length compared with their head diameter, along a flexible hose (26) to a movable rivet-installation tool has an aperture (18) running parallel to its axis along its whole length. Through this aperture a rivet can be both inserted into, and removed from, the shuttle. It also enables the sideways removal from the shuttle of an elongated mandrel, over the end of which a rivet has been axially fed. The exterior of the shuttle (11) and the interior of the hose (26) have similar cross-sections, which are a sliding fit and which co-operate with each other to maintain the shuttle (11) in a pre-determined rotational relationship with the hose (26), to facilitate insertion and removal of the rivet as aforesaid.

Abstract: In a fastener tool, a constant flow of compressed air is supplied. When the tool is not in use however the constant flow of compressed air results in waste. The tool is therefore provided with a trigger that is adapted when in a first position to stop the flow of compressed air through the tool in order to disable the tool and when in a second position to actuate installation means.

Abstract: A hydro-pneumatically operated repetition riveting tool, which tool includes a gripping means for releasably gripping an elongated mandrel at a position remote from the mandrel head, which gripping means comprises a housing with an internal taper, and a plurality of mandrel-gripping jaws which are urged into contact with the mandrel by means of the internal taper; hydraulic retraction means for retracting the mandrel, thereby to pull the head of the mandrel through a rivet on the mandrel and adjacent the head, thereby to place the rivet; return means for returning the mandrel forwardly again after placing a rivet; and rivet feeding means for feeding rivets forwardly towards the mandrel head; in which the return means is pneumatically powered; and in which the housing of the gripping means comprises a first part and a second part, spring means for urging the first and second parts relatively apart from each other, and limiting means for limiting the movement apart of the first and second parts under the urging

Abstract: A fastener installation tool for installing fasteners of the type in which a part of the fastener is broken off during installation. The tool is provided with a collection means for collecting broken-off fastener parts during operation of the tool, the collection means being removably connectable to the tool. The tool includes retaining means for retaining the collection means against removal from the tool and the retaining means is air-pressure actuated into the retaining condition. The tool may include resiliently urged shutter means which are held open when the collection means is attached.
