<p>An apparatus is described which can receive a large number of earplugs from a box and dispense one or two of them at a time to a worker. The apparatus includes a wheel (22) which is rotatable on a frame (12) and which has holes (24) that move in a circular path and that can each receive a single earplug (16). As each hole moves over a dispense passage (18), the earplug in the hole can fall out, and be dispensed. A barrier (42, Fig. 4) lying above the wheel, prevents an earplug from falling into a hole that lies at the passage. The barrier covers only one side (52) of the path (32) of the holes, to allow a deformed earplug to move along the other, uncovered side (54) of the path. The wheel has a narrow slot (80) extending from each hole to the periphery, so a tool can be projected through a frame opening (84) and through the slot to dislodge an earplug stuck in a wheel hole. The wheel has an upward projection (102) with inclined guideways (104) that each guide an earplug into a wheel hole.</p> |
