ABSTRACT:
A system for feeding coal or other material blown from a pipe in a desired trajectory is disclosed including a positioning device for applying directional force to the midsection of the pipe to produce slight bending for orienting the free end, which device has an horizontal adjustment member and a vertical adjustment member. Each comprising a slotted arm with an integral handle mounted on three congruent support plates and pivoted respectively in the interstices between the middle and outer plates. The plates have concentric circular openings therein through which a sleeve for passing the pipe therethrough axially extends. The sleeve also passes through the respective slots in the arms of the adjustment members, so that when the handle of the vertical adjustment member is pivoted in either direction about a pivot pin disposed through one side of the three plates, the pipe will be bent to displace its axis vertically, while pivoting of the horizontal adjustment member about a pivot pin passing through the lower portion of the three plates bends the pipe to displace its axis horizontally. The three plates are also provided with the locking pins which may be passed respectively through holes at the opposite ends of the slots from the pivots in each of the adjustment members to lock the members in their desired positions after adjustment.
