This article shows and describes a device for providing reliable feeding of set screws in a preoriented manner. It is often desired to use hex-socket setscrews in applications such as radial gears and anchored shafts. Automating these uses has been difficult in the past because headless screws are hard to feed in a reliable socket-up or socket-down orientation. The present device performs this orientation function prior to a pick-up operation by a screw-driving device. In the figure, screws 2 travel from a vibratory bowl (not shown) in tube 4 to escapement cylinder 6. Cylinder 6 is provided with a suitably configured screw-receiving well 8. Selector needle 10 with integral air jet projects into screw-receiving well 8 and connects to the axis 12 about which cylinder 6 pivots.
