Split′ting-ma-chine′.

A machine for dividing a skin of leather parallel with one of its surfaces.

Splitting-machine.

The leather-splitting machine (Fig. 5445) consists of a drum a, having an opening a′ running its whole length; the end of a hide is wedged into this opening, and as the drum is rotated, an endwise traversing motion being at the same time imparted to the knifecarriage b by means of a crank, the leather is drawn against the knife c, which divides it into two thicknesses, one part passing above and the other below the knife. The hide is held down and wrinkles smoothed out by a plate d, extending the whole [2282] length of the drum, and connected by a cord to a weighted lever e. The bearings of the drum rest upon a lever f at each end; this is raised or lowered to vary the thickness of cut by means of a screw g.

The knife-carriage b is provided with set-screws for setting the edge of the knife straight.

Leather-splitting machine.

In Fig. 5446, the leather is passed between the rolls and against a knife, the depth of the split being regulated by the upper or gage roller, the bearings of which are adjusted vertically by the hand-wheel shaft, right and left screw-threaded at its ends, and playing in wedges.
