ABSTRACT:
A fastener positioning apparatus includes a magnetized engaging element for slidably holding fasteners next to an elongated member as they are pushed from a first position into a hammering position by a positioning mechanism. In the hammering position, a hammering device seats the fastener into a desired medium. The entire fastener positioning apparatus may be placed on a cart for mobile use, and controlled so as to provide automatic placement of fasteners at predetermined intervals across the medium. Alternatively, manual control may be used instead of automatic control so that fasteners are positioned in accordance with specific selection of an operator. In the cart embodiment, a feed tube connects a tray for holding fasteners with a positioning device. The feed tube may include a vibrating device to ensure proper movement of the fasteners therethrough.
