Abstract
An improved fastener driving machine includes a driver, a support, a gear mechanism, an indexing apparatus, and a head. The head is movable among a plurality of positions with respect to the driver. The machine is advantageously structured to provide a substantially constant level of torque to a delivery point on the head independent of the position of the head with respect to the driver. The gear mechanism and the indexing apparatus are both disposed on the support, with the result that the mechanical operations of the gear mechanism are separate from the mechanical operations of the indexing apparatus. The indexing apparatus includes a number of tapered first teeth and a number of tapered second teeth that are securable to one another in a number of configurations to permit the head to be movably indexed to a number of positions with respect to the driver. The first and second teeth are biased together, and the indexing apparatus additionally includes a lock that locks the first and second teeth into engagement. An improved method is also disclosed.
