The Torpedo Conveyor. —A reciprocating conveyor has recently been introduced under this name, which presents some new features and an entirely different principle to the foregoing. Figs. 165 and 166 show the two types of this conveyor in elevation and cross section. The former is the standard type, whilst the latter is used when the available head room is limited. A conveyor according to Fig. 165 consists of the following component parts : the trough suspended on rockers c; the crank drive ag which conveys an oscillating motion to the frame b, which is supported by rollers h, rail i, and brackets k; and lastly of the dashpot/with its connection to the trough. Fig. 167 is a perspective view of the same. The conveyor in the lower illustration (Fig. 166) differs from the one previously described in so far that the upper rail is dispensed with, so that the rollers h revolve on the channel /, or rather on chilled iron rollers w, the rockers c being in this case much shorter.
