Another and excellent method of oiling, also invented by Mr. Hugh Thomas, of New York, is shown in [Figs. 1609] and [1610], in which p represents an oiling roll or wheel, V-shaped, to correspond to the shape of the Vs. This roll is laced with cotton wick or braid, as shown by the dark zigzag lines, and is carried in a frame f, capable of sliding vertically in a box c, which is set in a pocket in the bed v, and contains oil. By means of a screw s, the roll p is set to touch the face of the table V, and the friction between the roll and the V, as the table traverses, rotates the roll, which carries up the oil and lubricates the table V over its whole surface. The dust, &c., that may get into the oil settles in the bottom of the box c, which can occasionally be cleaned out. In this case the oil is not only presented to the oil grooves (h, [Fig. 1608]), but spread out upon the Vs; but it is nevertheless advisable to have the grooves h so as to permit of an accumulation of oil that will aid in the distribution along the Vs of the bed.
This method of oiling has been adopted in some large and heavy planers built by R. Hoe & Co., and has been found to operate admirably, keeping the guides and guideways clean, bright, and well lubricated.
