. Appleton's dictionary of machines, mechanics, engine-work, and engineering. MOTION. 425 which is the augur ; and the movement of the latter is followed by the box-shaped chisel, so that theresult is a square hole or mortise. The augur inside receives a very rapid motion from a bevel-wheel,geering into a pinion which drives the spindle K of the augur, a is a pulley to drive the wheel 0. Mis a lever, and by flanges the spindle is made steady to the back of the frame, and works down in guide-collars. When the hub, or whatever it may be, is in a correct position, the spindle K of the augur isset in motion, and the operator gently brings down the weighted lever M, cutting out the rectangularmortise. There is but little work for the outside chisel of the augur to perform. The fever rests on the top of the spindle, and it (the spindle) works by feather and groove to rundown through its geer-pinion, to follow the cut to the bottom of the mortise. These machines are highlyrecommended by those who have used them. 2847. MORTISING MACHINE. Figs. 2847 and 2848 represent a machine manufactured by W. R. &A. Inslee, Newark, N. J., and from the simplicity of its plan it is much less liable to get out of orderthan others of a more complicate character. The action of the machine is sufficiently obvious. MOTION, in mechanics, is a change of place, or it is that affection of matter by which it passes fromone point of space to another. Motion is of various kinds, as follows: Absolute motion is the absolutechange of places in a moving body, independent of any other motion whatever—in which general sense,however, it never falls under our observation. All-thosc motions which we consider as absolute are, infact, only relative, being referred to the earth, which is itself in motion. By absolute motion, therefore,we must only understand that which is so with regard to some fixed point upon the earth, this being thesense in which it is delivered by writers on this subject.
