Abstract: An engine with a cylinder assembly defining a cylinder chamber therein in which is reciprocally mounted a piston on a support tube slidably projecting on opposing ends of the cylinder chamber. A drive shaft is rotatably mounted through the support tube and a camming arrangement connects the piston and drive shaft to convert the reciprocal motion of the piston into rotary motion of the drive shaft. A pair of roller and guides alignment mechanisms are connected to opposite ends of the support tube externally of the cylinder assembly to prevent the piston from rotating but permit reciprocal motion thereof.

Abstract: A poultry conveyor for conveying birds in a poultry processing plant including a support frame, an elongate conveying trough, mounting means movably mounting the conveying trough on the support frame for movement along a generally horizontal path with the trough being inclined with respect to the horizontal, and drive means for reciprocally moving the conveying trough along the generally horizontal path to cause birds deposited in the conveying trough to be moved along the trough in a given direction.
