Claims

Claim lst In combination with a nail cutting machine, a transverse horizontal spindle carried in front of same and receiving position rocking motion through a series of levers and rods from a cam mounted on the cam shaft of the nail machine, said transverse shaft imparting such rocking motion through pulleys to a barrel or cylinder carrying the nail plate, either side of which is thereby presented to the cutters. 2nd The triple cam operating by its rotation, to give to the levers D suitably pivoted independent longitudinal and simultaneous lateral rocking motion. 3rd The barrel or cylinder holding the nail plate formed in two parts and rotated in different proportions of a complete revolution. 4th The combination, with the cylinder K, of spring N engaging with stop or recess in cylinder Kl and rotating it for the desired distance, and detent N3 for disengaging same. 5th The combination, with the cylinder rotated alternately in either direction and holding the nail plate, of nipping levers which, by means of a projection on the end of one engaging with a cam on the rim of the cylinder, simultaneously open the nippers and feed the nail plate forward. 6th The combination, with the cylinder holding nail plate, of a rod suitably carried, supporting the nipping levers and provided with retractile spring, and set screw for regulating extent of retraction and amount of feed. 7th In a nail feeding apparatus, the com¬bination, with the barrel holding the nail plate, of the nose pieces or conductors LL. 8th The stop Li secured on the bed plate and pressing against nose piece L. 9th The combination, with one of the standards carrying the cylinder, of the levers R and P operated by cam Q on shaft H, and arm 0 connected adjustably with lever P and having thereon spring S operating against lever K. 10th The combination, with the pulley H1 H2 and k of wire or other metallic ropes. 11th In a nail feeding apparatus, the transverse shaft carrying the feed mechanism and provided with devices whereby its position, with respect to the nail cutting machine, may be varied either vertically or laterally, or by which it may be moved further from or nearer to said machine. 12th The combination of the arm 0 secured to the nail cutting machine, so as to move free in two directions, and lever P connected with horizontal shaft carrying feed apparatus, these being provided with suitable means for connection together and, when detached, disconnecting the nail feed apparatus from the nail cutting machine. 13th In a nail feeding apparatus, the combination of the following elements, viz a cam on the shaft of the nail machine conveying initial motion, levers and rods for imparting same in either direction to rock shaft, a cylinder holding plate and rotated in either direction from shaft by metallic ropes, mechanism for feeding the plate forward and regulating amount of feed, devices for rocking cylinder while being rotated, and means for conducting plate to the bed plate and regulating same.
