Abstract: A drive tool having a top portion which is engageable with a drive source and a lower portion engageable with a fastener. The drive tool includes an axial load assist mechanism configured to urge the lower portion and upper portion of the tool away from each other (i.e. relative movement) such that a generally axial force is applied to the fastener engaged with the lower portion of the tool. As a result, the amount of upper body axial force an operator must apply to the drive tool to install the fastener is reduced.
Abstract: A fastener for cloth and similar materials is secured thereto by means of apparatus which includes an elongated member which is tempered in the form of a coil. Absent restraint the coil will move in a direction which is tangential to the envelope of the coil and carry therewith portions of the fastener and in cooperation with a base and a punch the members of the fastener are assembled.
