Obviously the invention is not limited to the details of the illustrative apparatus since these may be variously modified. Moreover, it is not indispensable that all features of the invention be used conjointly since various features may be used to advantage in different combinations and sub-combinations.
I claim:
1. In apparatus of the character set forth, a conveyor track, a conveyor carried by said track and guided thereon, a plurality of nozzles located in close proximity to the chain and adapted to deliver a cleaning fluid against the chain, said nozzles being located on opposite sides of the chain and offset longitudinally with respect to each other, said track having an opening therein in registry with said nozzles to permit free travel of the cleaning fluid through the chain.
2. In apparatus of the character set forth, a conveyor track equipped with bottom and side walls, said track having an opening therein, and at least two nozzles for directing a cleaning fluid against the chain, said nozzles being located on opposite sides of the chain and in close proximity thereto and being shaped to deliver against the chain a thin jet Whose width is substantially that of the chain, the opening in said track being in registry with said jets to permit free travel of the cleaning fluid through the chain.
3. In combination, a conveyor track equipped with a bottom wall and side walls, a conveyor chain consisting of rectangular chain links equipped with interlocking ball and socket connections, a nozzle supported directly above said track in close proximity to the top of the chain and adapted to direct cleaning fluid downwardly, and a second nozzle supported below said track to direct cleaning fluid upwardly against the bottom of said chain, said track being provided with a longitudinal opening through which cleaning fluid delivered from either of said nozzles may pass.
4. In combination, a conveyor track provided with a longitudinal opening in the bottom thereof, a conveyor chain comprising links which engag marginal portions in said track adjacent said opening so as to move over said opening, said links being provided with a central sprocket opening and with interlocking ball and socket connections, a nozzle supported above said chain, and a' nozzle supported below said track, said nozzles being offset longitudinally and being in registry with said opening in the conveyor track so that the cleaning fluid may pass through said chain.
5. Apparatus for cleaning conveyer chains and the like comprising, in combination, a plurality of steam nozzles located in close proximity to the chain at an idle portion of the run of the chain, said nozzles being shaped to deliver against the chain a thin steam jet whose width is substantially that of the chain, a guide for supporting said chain in fixed relation to said nozzles as the chain traverses the steam-jets, said nozzles being located on opposite sides of the chain and in close proximity thereto and being offset longitudinally of the chain so that the steam jets do not impinge'against each other, said guide having an opening therein in register with said jets to permit free travel of the steam jets through the chain.
