A high speed positioner for cylindrically or conical-shaped objects; such as pen caps, barrels, lip stick shells, flashlights or ammunition shells, which will orient and feed the elements supplied from a hopper, with one of the ends of the elements being pointed in a selected direction. A sensing device is provided on the feed bar to select one of the ends of the elements to be pointed downwardly in advance of the other end of the element into an orienting chamber for delivery to a vertically extending discharge chute. Other sensing devices and micro switches are provided in the positioner to control the operation of solenoid-operated air cylinder devices and air injectors used in positioning the work cylinder elements. The passing of the cylinder elements through the orienting chamber and the delivery tube can be observed through a transparent door closed thereover. A safety door at the bottom of the vertical chute is automatically opened to prevent a jamming of the cylinder elements at the lower end of the delivery chute, and by which access can be had to the chute, and by which a faulty element can be removed prior to being ejected from the lower end of the chute onto a pin or between jaws of a rotating table of machine on which work is to be performed by the machine upon the cylinder element.
