welldrno. woshbosrd tvpe, "Vl11.,FjeilGS of longitudinhlly extending a aoeirt bars .l treisverselv of oesigned for m, plying nails may be of the 24, in the upper edges of which are nail-receiving and conducting grooves or channels 26. The nail-Way is shown as formed in two sections 28 and 30 lying in substantially parallel planes or extending in the stone general direction, the former furnishing a body-portion which is in all essential respects identical with that of the Pope patent and having the bars 24: parallel to each other. This portion or section is continued rearwardly by the section 30, which includes a deliverythroat 32 similar in arrangement to the section 28, and diverging branches 34, 34:, in each of which the bars are parallel to one another, constituting two groups, which terminate, they converge in the direction of progress of the nails, in corresponding groups of parallel bars in the throat and body-portion. Each of the branches 3 f extends into the open side of a receptacle 36, shown as the customary druni adapted to contain nails in bull: and elevatii'ig and dropping them into the conveying channels 26. The drums preferably have their axes at right angles to each other, and are carried upon a rearward extension 38 from the base 10. Upon the extension are pairs of bearings it), 40 for supporting parallel shafts t2, &2, these pairs of shafts being at right angles to each other. Sleeves at, upon which rest flanges 46, 46 of the drums, have peripheral grooves -17 to receive the rear flanges and retain the drums against displacement. One shaft of each pair rotated through spiral gearing 48 from a shaft 50 extending horizontally from front to rear of the base and its extension. The shaft 50 is, in turn, connected by bevel gearing 5G to a vertical shaft 54 rotatable in the base and joined by spiral-gearing 52 to the main shaft The shafts 42 of each pair are connected to move together by a belt 55 running in grooves 57 formed in the sleeves 44-. By the shafting and gearing, the sleeves 44; are maintained in constant rotation in the same direction during the operation of the machine, communicating this motion to the drums, thereby causing them to lift the nails and drop them into the grooves of the branching conveyor-portions 84-, so these are continuously supplied.

Associated with the body-portion 28 of the nail-way is a reversing device 58. This consists of a plate or member (30 having grooves 62 and supported at the forward extremity of the throat 32 of the conveyor section 30 and over the rear of the section 28, being spaced from the former at 6 1:. The grooves 2 in this plate are alined with those of the conveyor. This reversing device acts in the usual manner to insure all the nails passing along the grooves 26 being delivered with their heads foremost. The space at 64. is such. that nails traveling along the channels under the influence of the re ciprocation of the conveyor, and entering this from the throat with their heads in advance, will overbalancc and fall into the grooves of the section 28, Without contact with the reversing device. If, however, the points are foremost, gravity does not act until the nails have bridged the space (ilwith their forward extremities resting in the grooves 62, they then continuing the advance until the heads leave the throatgrooves, again falling head-down. To adapt the reversing device to act effectively upon nails of different lengths, the plate is adjustable to vary the width of the space 64: by

means of racks and pinions U5 connecting it to a shaft (36 arranged for manipulation by the operator. li y moving the plate toward or from the adjacent extremities of the grooves in the throat ti l, the width of the space ilmay be varied to cause the correct CO-OPGl'tflOIl ot' the revc g plate With nails of the particular length at that time passing through. the apparatus. This provides for nails from the group of channels in one of the branches ili hiince the other group de livers another length of nail, the plate (30 has alined with the second group an independent section (it? mounted upon the plate for movement in the same direction thercas, and being lined in place by a slot-aud-screu" connection. 70. The grooves in this platesection (35% correspond to those of the other con\"eyor-branch 3 1:, and the section may be :uljueted, regardless of the p 'on of the main section, to properly reverse the nails upon which it acts.

From the forward tnztreniitics of the chainicls in the body-portion 538 of the con veyor, the nails pass to a discharge device 72, Which controls their time of delivery to conduits T t leading to the machine supplied. This device includes a roll 76 journalist transversely at the end of the conveyor-- channels and having a series of passages Tl; respectively alined with such channel The roll is oscillated through connections 80 from a cam 82 upon a shaft til; journaled at one side of the frame This shaft is rotated by gearing 86 from the main shaft 22. Upon leaving the channels of the conveyor, the nails are received by the passages 78, which are normally alined with said channels, and there held for an interval determined by the contour of the :am 82, the roll being turned at the prziiper time to further incline the T8 and discharge the rolls into the conduits 721-.

To hold the nails upon the device T2 ready for discharge, they contact with a stop device 88. This device inchules a body-portion, which may consist of a plate til) can tending across the extremity of the couveyor parallel to the axis of the roll Til. The plate is connected by racks and piniltins 92 to a shaft thiundcr the control of the lilo a n through slots llet in the carrier-bars.

operator, the rotation of this shaft producin an adjustment of the plate toward and from the discharge-roll. .h lovable in ways 96 extending, transversely of the plate is a slide 98 having a depending portion 100 cum red by a screw ill/2 threaded into the plate below the slide. By this means, the slide may be varied in its relation to the discharge-roll independently of a correspond ing adj uslinent of the plate 90. The slide is reces at 10 and at L06 the plate is similarly recessed. In the ways thus provided slide carrier- bars 108, 108, pressed normally out toward the discharged-ell by springs llO lo rated between the carrier-bars and the inner walls of the recesses. The extent of movement of the carrier-bars is limited by pins 112 fixed in the slide and plate and extendi across the recesses Pivoted at 116 upon each carrier-bar is a stop her which, in the nail-retaining position, lies over downwardly inclined surface 120 at the forward ends of the. pas- 78, each of the bars presenting a stopsurface throughout its entire length equally distant from the passage-openings. Each bar-section is adjustably supported upon its pivot by a screw 122 threaded vertically through the carrier-bar and having at its lower end an enlargement i'or engagement with a horizontal slot at the inner side oi the corresponding bar. Each screw may secured in its adjusted position by a lockout 1526. Upon turning either of the screws, its bar may be raised or lowered, so that its relation to the surface 120 of the dischargeroll may be altered. There thus exists a capacity for adjustment of one of the stop .ars toward and from the passages 78 in the nail-roll, these passages corresponding; to group of the nail-channels continuing those of one of the conveyor-branches This adjustment is eli'ected by moving the plate 90 as a whole by means of the shaft 94-. The other stop-bar cooperating with the group of discharge-roll-passages belongingto the other conveyor-branch is independently adjusted by means of the screw 102. Thus, the space between the bars and the ends of the nail-channels may be brought into accord with the lengths of delivered by such channels. Because the surface 120 is downwardly inclined, such an adjustment as that just described varies the vertical relation of the lower edge of each stop-bar to the surface. Unless this were compensated for, a space would be opened below a bar when it was adjusted outwardly, which would tend to interfere with the proper arresting of the movement oi nails and their discharge. The raising or loweri c of the stop-bars by the screws 2 per sits the maintenance of a uniform distance between the bars and inclined surface, the adjustment being independently accomplished for the respective bars. This is rendered necessary by their varying positions horizontally, because of their co-operation with nails of two lengths.

In using the aii 'iaratus, nails of the desired lengths are put in the two drums at, 36, to be elevated thereby to the grooves of the converging conveyor-branches 3 1, 31-. Passing down these to the throat Eli 2, they fall through the space (34-, revi'u'sed, if necessary, by a device 58, so their heads are all pointing forward. 'ro 'irovide for the proper action ot' this reversing device upon the particular lengths of nails which may have been placed in the drums, the plate 60 and the section 68 are separately adjusted, either iy turnii'ig the she-l t 66 or altering; the position of the upper section upon the plate by means or" the slot-and-screw connection T0. Further advancing along the grooves of the body-portion 28, the nails enter the passages 78 k the discharge device '72, being temporarily stopped by the bars 118. The proper distance of these tr in the alined groups of channelsconveying the two lengths oi nails is provided For by'either movement of the shaft 9% to shift the plate as-a whole, or the screw 102 to vary the position of the slide 98. As the relat on of the bars to the surface 120, upon which the nails rest in the dischargeroll, is changed by tillSlllOVQlllGIlt of the bars, the latter are correspondingly raised or lowered by the screws 122 until they are in position to bestretu-iu the nails for delivery. Thus held, the loads aresuccessively discharged by oscillatioi'i oi the roll 76in an anticlockwise movement, as viewed in Fig. 3 of the drawings, into the conduits '1 passing therethrough to the loading mechanism of the heeling or other machine supplied. Since, in the main, the

elements of my improved nail-distribu tor for operating upon nails of different lengths are identical with those of an apparatus adapted for use in connection with a single length of nail, a manufacturer of both types of apparatus will be required to produce and carry in stool: a much less number of parts than were the designs unlike. It is also desired to point out that generally the structure is simple and ellicient, the arrangement not being complicated by the increase in the service performed.
