Appletons' cyclopaedia of applied mechanics: a dictionary of mechanical engineering and the mechanical arts . the table, which is moved by the attendant upon the tracks shown. The platform of the tablehas a to-and-fro motion on its supports, so that any portion of the hide can be presented to theslickers as may be desired. This machine slicks from 60 to 70 sides daily, and is easily managedby one man. Graining Machine, Fig. 2763.—This apparatus takes the place of the graining board operated by LEATHER-WORKING MACHINERY. 283 hand. A is the graining board, which is oscillated by the pitman from the large gear-wheel shownon the right. The most important feature of the machine is the table JB, which is made of a seriesof separate pieces arranged side by side like the keys of a piano. These pieces are supported on. springs, which yield under the pressure of the graining board to an extent proportional to the thickness of the leather. By tins means the apparatus is enabled to work upon thin or thick hides withequal facility. Its capacity is from 10 to 12 sides per hour. Motive power required, 1 horse. 2764.
