<p>Automatic driving apparatus which sequentially inserts screws provided with washers into work pieces includes a chute formed with an opening transverse to its axis. Screws are fed sequentially through the opening into the chute. A driver in the chute is shaped for driving engagement with an introduced screw. A drive mechanism axially moves the driver in the chute and rotates the same in a plane transverse to the axis for thereby engaging the driver with the screw and axially moving the screw with the rotating driver. A magazine adapted to hold apertured washers is provided with a slide which sequentially moves the washers transversely to the chute axis from the magazine to a position of alignment of an aperture in the moved washer with an axially moving screw in the chute. A source of motive power is connected with the feeding mechanism for the screws, the drive mechanism, and the slide for transmitting motive power to the feeding mechanism, the drive mechanism, and the slide in timed sequence.</p> |
