| 20090069102 | METHOD AND APPARATUS FOR COLLATING NAILS - An apparatus and method for collating nails wherein round head nails are fed by gravity along an inclined rail to a periphery of a rotating indexing and feed wheel. The nails are deposited into circumferentially spaced grooves formed in the periphery of the feed wheel in a vertical orientation. The feed wheel is inclined at an angle of approximately 45° and upon 180° rotation of the feed wheel the nails assume a horizontal orientation. A conveyor has a plurality of spaced segments attached to a pair of moving belts. Each segment is formed with spaced notches for receiving the nails in a horizontal spaced relationship from the feed wheel and then transporting the horizontally spaced nails to a collator for forming into a continuous strip. Rotation of the feed wheel is synchronized with movement of the conveyor by a motor, a gear train and drive shafts extending between the feed wheel and conveyor. | 03-12-2009 |
| 20110098122 | APPARATUS AND METHOD OF MAKING A HEEL-LESS NAIL - A full-round head nail having an offset head is configured with a gusset formed integrally between an undersurface of the offset head and a superior portion of a shank. The head of the nail is relatively thin, and the shank is positioned radially off center of the round head such that no heel is formed at a point tangential to both the head and the shank. The gusset has a lofted surface tapering radially from a roundness at the zero heel to a taper at the toe. The gusset reinforces the junction of the shank with the head, supports the toe of the head, and distributes the force of a load on the head through a longitudinal axis of the shank, preventing the toe from bending or yielding and prevents the shank from yielding to the stresses of the load applied. | 04-28-2011 |
