This is the design of Alfred Godfrey, of Clapton. According to this improvement, as represented at Figs. 1 and 2, a rack, A, is employed vibrating on the pivot a, and a pinion, a1, so arranged that instead of the pinion moving on a universal joint, or the rack moving in a parallel line from side to side of the pinion at the time the motion of the table is reversed, there is employed, for example, the radial arm, a2, mounted on the shaft, a3, supporting the driving wheel, a4. The opposite or vibrating end of the radial arm, a2, supports in suitable bearings the pinion, a1, and wheel, a5, driving the rack through the medium of the driving wheel, a4, the effect of which is that through the mechanical action of the vibrating arm, a2, and pinion, a1 in conjunction with the vibrating movement of the rack, A, an easy, uniform, and silent motion is transmitted to the rack and table.
