The commodity-carrying member of a‘ slicing machine, usually called the commodity tray or trough‘, comprises a trough-like structure which is .mounted for reciprocation on a" slicing ma chine base to carry themain piece of commodity past the exposed edgeof the knife. A commod ity tray is usually provided with a commodity clamp which may be ‘fed transversely across the commodity tray toward the plane of the knife byv means of a spring to force the commidity commodities ?rmly and’ will also protect the hands of the operator.

At the lower portion of the turned-over side 25 of the plate 23 there is located a series of commodity engaging prongs 35 which are shown in I as engaged in a sausage-like commodity 35. The action of the spring I8 forces the arm in a counterclockwise direction inserting the prongs 35-into the commodity 36 and also pushes the arm '29, commodity clamp 22 and engaged commodity toward the gauge plate I3 while hold ing the commodity in the corner of the com modity tray Ill.
