A drive mechanism for the reciprocating meat supporting carriage of a meat slicing machine wherein the carriage supports the meat product to be sliced and moves the meat product relative to a power driven knife, and which includes an endless belt trained over longitudinally spaced apart pulleys, thereby defining upper and lower horizontal belt runs extending between the pulleys, a drive member connected along the belt and having a driving lug mounted intermediate the ends thereof, the driving lug slidably engaging a drive slot formed in a driven bar extending from the carriage, the slot extending perpendicular to the direction of movement of the carriage, and the ends of the drive member being connected to the belt such that the path of the driving lug during the time the connected ends of the drive member traverse the pulleys follows a path substantially longer than the path of either connected end of the drive member, whereby the deceleration and acceleration forces of the driving lug are substantially less than those of the connected ends of the drive member.
In a meat slicing machine including a power driven slicing knife, a reciprocably mounted carriage for supporting meat to be sliced, a driven bar connected to said carriage having a drive slot extending perpendicular to the movement of said carriage, and means engaging said drive slot for reciprocably driving said carriage relative said knife through cutting and return strokes, the improvement in said reciprocable drive means which includes an endless belt trained over longitudinally spaced apart pulleys defining upper and lower horizontal belt runs between the pulleys, means driving at least one of said pulleys, a drive member connected to said belt and having a driving lug mounted intermediate the ends thereof and in substantial alignment with said belt during movement along the horizontal belt runs, said lug slidably engaging said drive slot, and means connecting the ends of said drive member to said belt such that while the connected ends of the drive member traverse a pulley the path of the lug between the horizontal runs is substantially longer than each path of the connected ends of the drive member thereby decreasing the acceleration of the lug and carriage at the ends of the cutting and return strokes.
