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

Apparatus for swaging a collar onto an externally grooved member

A shuttle () for feeding tubular rivets (), which are of relatively short axial length compared with their head diameter, along a flexible hose () to a movable rivet-installation tool has an aperture () 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 () and the interior of the hose () have similar cross-sections, which are a sliding fit and which co-operate with each other to maintain the shuttle () in a pre-determined rotational relationship with the hose (), to facilitate insertion and removal of the rivet as aforesaid.

Shuttle and component feeding system

A fastener installation tool for installing breakstem fasteners, wherein a part of the fastener is broken off during installation and ejected into a collector bottle, provided with a safety disabling means, comprising a valve located in series with and between the tool trigger and main operating valve, wherein removal of the collector bottle causes the valve to close to prevent operation of the main operating valve, thereby to prevent use of the tool with the connector bottle disconnected.

Fastener installation tool

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.

Fastener installation tool including means for disabling the tool

A nose assembly for fitting onto a fastener installation tool for installing fasteners of the type in which a part of the fastener is broken off during the installation process, the nose being provided with a housing and a sleeve, the sleeve having a spring, and a collar which is movable within the housing against resistance of the spring, wherein plunger means are provided on the collar, and wherein the sleeve is threadably engaged with the collar, such that movement of the sleeve causes corresponding movement of the collar and plunger means, the plunger means being arranged to actuate a trigger thereby to open an air valve and allow a flow of compressed air through the tool, thereby to allow installation of the fastener into a workpiece.

Nose assembly

Riveting apparatus of the type in which an elongated mandrel, having an enlarged head at one end and loaded with a plurality of the tubular rivets forming a column of rivets on the mandrel, is gripped by gripping mechanism at or near the end remote from the head, and reciprocated relative to an abutment (32), by relative reciprocation between the gripping means (43) and the abutment, the rivets in the column being fed forwardly along the mandrel so that the leading rivet nearest the mandrel head is positioned between the mandrel head and the abutment (32) and can then be set by moving the mandrel rearwardly relative to the abutment (32) so as to draw the head of the mandrel through the bore of the rivet while the rivet is supported by the abutment (32), includes pneumatically operated rivet-feeding mechanism for feeding rivets forwardly along the mandrel, a valve mechanism for shutting off the supply of air to the rivet feeding mechanism thereby to disable it, and the valve mechanism is responsive to the presence or absence of a mandrel in the gripping mechanism (43) the valve mechanism being closed in the absence of a mandrel and open only in the presence of a mandrel.

Riveting apparatus

A riveting apparatus which includes an elongated mandrel, a mandrel gripping mechanism, a mechanism for feeding rivets forwardly along the mandrel, and an abutment provided by a plurality of members, and a control system including an actuation device such that, upon actuation by an operator of the actuation device, the control system controls the riveting apparatus so that the rivet feeding mechanism is activated and deactivated, the abutment members are closed or opened, and the mandrel gripping mechanism is activated or deactivated, with a time delay between each step, to enable rapid removal and replacement of the mandrel.
