In Letters Patent 01' the United States No. 1,657,630, Lund, January 31, 1928, is shown a two-length nail-distributor to which the present 5 invention may usefully be applied. I have herein illustrated a portion of this apparatus, there 29, 20 from rotatable drums or other sources, a fragment of one drum the forward extremity of the secondsection of 25 a bar 22, with which the groups of raceways, 28 corresponding to the in position upon the bar. The section 28 is shown as by a slot-andried by transverse shafts 32, displace nails which may be crossed on the raceways. The nails are picked oil from the forward extremity of the 45 6 and 18 from one another longitudinally of the conveyor are shown comparatively low walls, that of the upper section I2 being identified by 50 the numeral end of the conveyor-section It may 58, 58 projecting jection 38 near its forward extremity by a screw 44 is a partition 4'6, provided with a slot to receive the screw. The rear of the partition is held against lateral displacement by lugs 48 extending upon opposite sides of the wall 38. An auxiliary partition 49, through an opening in which the roll 33 passes, may divide the raceway groups adjacent .to said roll. The partitions it, 46 and 49 are preferably of sheet-metal. With those desand 56, they furnish sections of a composite partition extending preferably the length of the raceway.

In the various positions to which the reversing bar 22 is adjustable, the interchange oi nails between the raceway-groups it: and iflat thelower be sufficiently guarded against by extending the partition Mi above the wall 36 or" the bar and furnishing it with a depending end 50 entering a slot insaidwall. The lower partition 46 might similarly enter a slot in the opposite side of the bar, but the width of this bar will not permit such an arrangement to furnish unbroken dividing means between the raceway groups for the max imum opposite adjustments of the bar. The direction in which the nails would approach an open slot would also be disadvantageous. I prefer to maintain such a complete division at the forward side where the mixing of the different lengths of nails, especially those which have become crossed upon the raceways, is most liable to occur. For this purpose, the partition 46 has a portion 56 arranged to slide upon it, the partition being shown as having. spaced, headed studs from one side through a slot 59 in the slide 56; Between an upward projection 60 from the partition and a corresponding pro- 62 from the slide extends a tensionspring 64,. exerting its force to draw the slide rearwardly-and its end into engagement with the forward face of the reversing bar 22. The slot 59 is of such length that the slide may follow the bar in the adjustment of the latter to its extreme inward position. When the bar is carried for extending from its upper edge and bent down substantially parallel to the body of the slide. This arm completes the closure beyond the inner end of the partition 46.

It will be seen that as the nails traveling down the conveyor are displaced by riding over one another, becoming crossed upon the raceways, and by the jar to which they are subjected during the oscillation of the apparatus, they will be retained by the partition of this invention in their own groups, the sections which make up said partition being arranged to furnish a substantially continuous division between them whatever position the reversing bar may occupy.

Having thus described my invention, what I to. the conveyor and a portion guided end of claim as new and desire to secure by Letters Patent of the United States is:

1. In a nail distributor, a nail-conveyor provided with groups of raceways extending adjacent to one another, and a partition dividing the groups of raceways and having a portion movable to correspond to the position of a conveyor element. with which it co-operates- 2. In a nail-distributor,.a nail-conveyor provided with groups of raceways extending adjacent toone another, and a partition dividing the groups of raceways and including a portion fixed for move ment thereon. a

3. In a nail-distributor, a nail-conveyor provided with groups of raceways extending adjacent to one another, a partition dividing the groups of raceways and including a portion fixed to the conveyor and a slide gu1ded for movement thereon, and a spring acting to draw the slide into contact with anelement of the conveyor.

f1. In a nail-distributor, a nail-conveyor pro vided with upper and lower sectionsin which are groups of raceways, an adjustable nail-contact member mounted near the juncture of the sections, means arranged to move the contact member, and a partition dividing the groups of raceways and having a portion engaging the contact member andmovable with said member during its adjustment.

5. In a nail-distributor, a nail-conveyor provided with upper and lower sections in which are groups ofraceways, an adjustable nail contact member mounted near the juncture of the sections, means arranged to move the contact memher, and a partition dividing the groups of raceways, there being a slot in the contact member to receive the partition.

6. In a nail-distributor, a nail-conveyor provided with upper and lower sections in which are groups of raceways, a reversing bar extending across the lower section oi the conveyor and contacting with nails from the upper section, means for adjusting the bar toward and from the upper section, a partition extending across the bar and corresponding in position to the division between the groups of raceways, said bar-partition being provided with a slot, and a partition dividing the groups oi raceways upon the conveyor and received in the slot. 7

*7. In a nail-distributor, a nail-conveyor provided with upper'and lower sections in which are groups of raceways, a across the lower section of the conveyor and con tacting with nails from the upper section, means for adjusting the bar toward and from the upper section, a partition formed in sections'which divide the groups of raceways upon the conveyor and extend across the bar, said partition being provided with a slot in one section receiving the p another section at one side of the bar and with a slide yieldable in contact with the opposite side of the bar. p CHARLES H.
