PCT No. PCT/SE83/00199 Sec. 371 Date Jan. 6, 1984 Sec. 102(e) Date Jan. 6, 1984 PCT Filed May 20, 1983 PCT Pub. No. WO83/04209 PCT Pub. Date Dec. 8, 1983.A device for the positioning and individual feeding of nails comprises a nail filling container which is pivotal upwards and downwards about a horizontal pivot shaft and in the bottom of which there are formed one or more slots which are substantially perpendicular to said pivot shaft and in which the shanks of the nails can be accommodated while the nails are maintained suspended by their upper parts, for instance their heads. According to the invention, each slot (22) passes and extends beyond the wall located at the discharge end of the container (21), and forms a feed slot (22', 22'') which protrudes outside the container (21) and in the end portion (30) of which there is provided a stop (25) of such a design that the outermost nail (28) of the fed nails (23'') is maintained in a correct position at the outermost end of said end portion (30) which is spaced from said pivot shaft (24) such that the end portion will perform a substantially vertical oscillating movement between a lower end position ( 27) and an upper end position (26). The end portion (30) of the feed slot may have a depression which is of such a length that only one nail (28) can be received in the depression between the stop (25) and the shoulder of the depression which is located at the proximal end thereof with respect to the pivot shaft (24). A gripping member (29) is adapted to seize the nail-carrying upper part of the outermost nail (28) when in the upper position of oscillation (26) of the end portion (30). The oscillating movement has such a magnitude that the outermost nail (28) is completely withdrawn from the end portion (30) of the feed slot when the end portion occupies its lower end position (27). The gripping member (29) is adapted to horizontally displace the nail (28) a certain distance (35) for supplying it to the nailing site.
