Abstract

140,766. Constanzo, A. di. March 22, 1919, [Convention date]. No Patent granted (Sealing fee not paid). Toothed gearing; chain gearing.-In a digging- machine the main slide carrying the spade may be reciprocated by the toothed gearing shown in Figs. 14, 14<a>, or the chain gearing shown in Fig. 17<a>. The driving pinion 86, Fig. 14, engages a pinion 87 mounted on an arm 88 loosely mounted on the driving-shaft. The pinion 87 meshes with an internally toothed rack 89 of the shape shown. A roller 90 on the pinion 87 moves in a groove 91 shaped like the rack. In a modification in which the rack has external teeth, the two pinions have equal diameters and the groove and roller are dispensed with. In the arrangement shown in Fig. 17a, the slide is moved by an endless chain 102 driven by a wheel 103 and carrying a roller projecting into a transverse slot 106 in the slide 107.
