Abstract: A nose piece for inserting fixing elements into predefined seats in a work piece includes a drive channel for receiving a lower end of a drive rod. The drive rod is movable from an initial upper position, through a first intermediate position, to a lower position when acted on from above on by a drive force. A lower face of the nose piece is adapted to receive a first fixing element. At least one finger is biased toward a side wall of the nose piece. When the drive rod exerts a force on an actuator, the actuator moves the finger from a closed position, in which a lower portion of the finger is disposed under an outer portion of the flange of the first fixing element, to an open position, in which the lower portion of the finger is disposed away from under the outer portion of the flange of the first fixing element.

Abstract: A portable device for inserting fixing elements into predefined seats in a work piece, the portable device including a drive head; a drive rod extending downward from the drive head; a hollow nose piece slidably fit around a lower end of the drive rod, the nose piece being attached to the head and being movable vertically by a predetermined distance with respect to the head and the drive rod; a magazine mounted on the nose piece at a predetermined angle with respect to a lower face of the nose piece for feeding a first fixing element into a horizontal slot on the lower face the nose piece; and a single-blow drive mechanism providing a force produced by a pressurized fluid to an upper end of the drive rod when the drive mechanism is triggered. The force on the drive rod drives the first fixing element into the predefined seat in the work piece.

Abstract: The method of the present invention is intended to be used in association with a headed fastener such as a tee nut, but not limited to a tee nut. The present method contemplates embodiments of a riveting pin having protuberances that cause the flared end of the shaft to be flared in one or more discontinuous portions of the circumference of the shaft, whereby “push out” and “spin-out” are deterred. Where the length of the fastener shaft is no longer than the thickness of the material through which it is inserted, a first design of flaring pin is provided. Where the length of the shaft of the fastener employed is greater than the thickness of the material through which it extends, a second embodiment of flaring pin is employed. In the former case, at least one discrete portion of the circumference of the shaft is flared into the wall of the passageway through which the shaft extends.
