Abstract: A bar and tube feeder having a narrow frame including a horizontal box beam of rectangular cross section and a pair of upright legs, a continuous conveyor comprising an endless chain mounted on sprockets near the opposite ends of said box beam, spaced bar-supporting carriers mounted on the chain, a guide bar on the beam for holding the upper flight of the chain parallel to the beam, means for supporting a stack of long bars parallel to the upper flight of the chain, and an improved escapement means to feed the lowermost bar from the stack to the carriers. The box beam has a length at least 10 feet and provides the main reinforcing element of the frame. The frame, including the legs and escapement means are narrow and have a width only slightly greater than that of the box beam so that the bar feeder occupies a minimum amount of floor space.
