NAIL DISTRIBUTOR.

Application filed September 2, 1921. Serial No. 498,074.

furnished by a rotatable roll, is mounted between the nail-delivering ways and a stopbar, and oscillated between one eXtreme position, in which the nails are received 1n depressions inthe roll which are alined with the nail-ways and stop, and the oppo-v site eXtreme position, in which the nails are discharged from the roll-depressions into conduits which supply loading mechai5 nism. In this discharge mechanism the stop-bar is adjustable toward and trom the roll, so that nails ot different lengths may be operated upon successfully, the location of the bar always being such that the nails f) stopped upon the roll prior to delivery will hold the succeeding nails clear oi' said roll in its discharging movement. l/Vhen, howover, the length of the nails falls below a certain minimum for a roll of. a particular diameter, the adjustment which would stop them with their inner extremities at the desired position is prevented by the bar coming in contact with the periphery of the roll. Rolls ot' small diameter, to give a wider range of stop-bar adjustment, cannot be used with long nails, since they afford for these an unstable support from which the vibration ot the apparatus displaces them. It is therefore customary to provide a plurality ot interchangeable rolls ot' different diameters, each ot which will act properlythrough a certain limited range oi naillengths. The present invention has as an object the simplification ot this multipleroll equipment by the provision of a discharge mechanism, which by adjustment only, without substitution ot elements, will act successfully with all lengths et nails. To this end, a movable discharge device, as a rotatable roll., has combined with it :i mov-a Vable stop member, which may be a reciprocatory bar, extending into the path oit said discharge device and of the nails. delivered thereby. lVhen thus related, the stop member may be carried inwardly toward the nail-ways in its adjustment, so that it will maintain even the shortest nails in the correct relation upon the roll to those tollowing in the nail-ways. To permit the movement of the discharge device when the stop member is related to it as just set forth, the latter is preferably yieldable and the discharge device has provision for automatically moving the member out of its path in advance of the nails delivered. This movement I have shown as accomplished by a cam-surface, which may be formed upon the discharge-roll. In addition to this automatic movement ot' the stop member, there is provided means arranged to adjust the stop member with relation to the discharge device to position it for the particular length of nails to be delivered.

Of the many forms which my invention may assume, but one is illustrated in the accompanying drawing,

Fig. l being a side elevation ot the t'or- Ward portion of a nail-distributing apparatus to which my improved discharge mechanism is applied; i

The general nail-distributing organization may be similar to that disclosed in Patent No. 1,005,303, Pope, Oct. 10, 1911. This includes a nail-conveyor 10 arranged to reciprocate in a frame 12 and provided with inclined grooves or nail-ways 14 carrying the nails from a drum or container (not illustrated) in series in each of the ways, as appears at N in Fig. 4, to the discharge mechanism D. The discharge member proper appears as a roll 16, journaled horizontally for rotation upon the forward end of the conveyor-frame. The roll 16 is os- `d-le to alternately release the nails to permit their travel down the nail-Ways to the discharge mechanism and checl; this advance Whilesaid discharge mechanism is operating, These fingers have no peculiar relation to the present invention.

Extending longitudinally of the axis of vthe discharge-roll and opening through its periphery is a recess 2li, Which approximately has the form which would be produced by removing from the roll a sector of 90 degrees. In the normal or nail-receivingl position of the roll (Figs. l anc G), a Wall 26 of the recess lies horizontally, while the other Wall 28 extends vertically. Opening through the Wall 28 and through the opposite side ofthe roll isa series of transverse perforations 30, corresponding in number to thenailvays, being alined with them and having the same inclination when the discharge-roll occupies the nail-receiving Aposition. In the opposite extreme position, illustrated in Fig. 5, the perforations 30 are so inclined that they discharge the contained nails by gravity into conduits 3l leading to the loading mechanism of the machine, as a heeler, which .is to be supplied. Entering the roll-recess 2t, so that it lies in the path of movement of said roll in its oscillation, is a stop member, shown in the formof a bar This bar preferably is parallel to the normally horizontal wall 26 of the recess, and has a vertical stop-surface 8l parallel to the recess-wall 2S and extending across the for-ward ends of the perforations 30. The bar is mounted to reciprocate in a horizontal Way 36 in a plate 38 mounted for adjustment toivardand from the Adischarge-roll upon the forward portion of the conveyor-frame. This movement may be effected by a shaft 40 arranged to be turned by a hand-Wheel e2 and having fast upon it pinions et, 44 meshing ivith series of rack- teeth 46, 46 upon the upper face of the plate. The stop-bar is pressed yieldahly toward the discharge-roll along lines at all times intersecting it by springs 48, tivo of which may be employed, these springs being contained in bores in extensions 50 from the outer edges `of the plate. 'The forward extremities of the Abores are threaded to receive screw-plugs 52, 'against which the inner ends of the springs abut. By turning these plugs toward or from the stop-bar, the force ifi/ ith Which the springs resist its movement may vbe varied. The inivard travel of the bar under the expansive force of the springs may be limited by pins 54e extending across the Way 36 and held by the upper and lower `walls ofthe plate 38. These pins pass through slots 5b in the stopbar, the elongation of the openings permitting the desired yield of the bar. Formed upon the roll 16, as an extension of the recess-Wall 28 and above the perforations 80, is a cam-surface 58 arranged to contact, in the oscillation of the roll, with the stop-surface 3st of the bar or with an upivard extension therefrom.

In using this discharge device, the stopbar 32 is adjusted by moving its supporting plate 38, until the Wall .3f-t is in such a position that contact of the forward ends of the nails, as they lie in the receiving depressions 30, will bring the opposite extremities just outside the periphery of fthe roll to hold the succeeding nails spaced from said roll. This is as illustrated in Fig..l, for the shortest nail Which the mechanism is adapted .to operate upon, and as in 6, for a longer nail. Even when the stop-bar is adjusted for the longest nails, with the surface Se farthest from the perforations 30, there willv be no danger of displacement of the nails by the ari-ing of the apparatus, since they are held positively against the upward movement Which would dislodge them, by the closed perforation-Walls As the roll 1G oscillates in the direction of the arroivs in Figs. 4 and 5 ofthe drawing to discharge the nails, the cam-surface 5S, operating against the stop-surface C54-, forces the bar forward, the springs i8 yielding. Thus ,the rollimoves the bar outof its path, as is Yparticularly shownin Fig. leaving saidroll free to oscillate. This at once carries the stop-surface of the bar away from the delivery-ends of the .perforations, and the nails contained in ,the pcrforations fall, without anything to interfere with their dischar-ge,.over .the recess-surface 2G into the conduits As .reverse movement of the roll occurs, the springs 48 ycause the bar to follow the 'surfaces 58 and 28 `bach to the normalreceiving position, whereupon .the nail-receiving and discharging operation is repeated.
