Abstract
Abstract An apparatus and method for orienting elongated headed articles such as nails and the like. A pair of rotatably mounted, horizontally disposed orienting rolls have helical grooves of opposite hand. The rolls are rotated in opposite directions and such that the surfaces of the rolls move upwardly through a slot formed between the two rolls. The elongated articles are dumped onto an orienting end of the rolls and by rotation of the rolls fall between the slot with the heads of the articles being retained between the rolls. The articles are worked into the roll grooves which mate at the slot and are moved in the grooves by rotation of the rolls to a discharge end of the rolls wherein they are removed therefrom seriatim in oriented form. The apparent motion of the mating grooves is toward the discharge end as the rolls rotate. Rejection means, such as pins or brushes on the rolls at the discharge end thereof, remove articles which are horizontally disposed between the rolls. The articles are fed to the orienting rolls by a rotating drum which surrounds the rolls. The drum has radially oriented baffles for lifting the articles and dumping the same onto the orienting end of the rolls.

Claim 3
Dependent Claim
32 words
An apparatus for orienting articles according to claim 1 wherein said rotating means rotates said roll such that the surface thereof moves upwardly through said slot to prevent jamming of articles therein.
Claim 4
Dependent Claim
63 words
An apparatus for orienting articles according to claim 2 wherein the other of said orienting members includes a second roll having a helical groove of opposite hand to that of said first roll and in alignment with said helical groove of said first roll; and further comprising means for rotating said second roll in a direction opposite to that of said first roll.
Claim 5
Dependent Claim
44 words
An apparatus for orienting articles according to claim 3 and further comprising rotating means on at least one of said orienting members at said discharge portion for removing articles disposed horizontally between said orienting members so that said articles fall back into said hopper.
Claim 6
Dependent Claim
63 words
An apparatus for orienting articles according to claim 3 wherein said first and second rolls have a section in which the diameter increases slightly in a tapered fashion between said orienting portion and said discharge portion whereby said rolls operate more positively on said articles within said grooves as said articles move from said orienting end to said discharge end of said rolls.
