E i i awe/MW? therefore to the hoes connected to the latter. At the ends lll restingagainst the ring 2,the arms oit the hoes inclose partially the pins 13 securedv to the-inner plates The end lelo the aiin of a hoe projects between pin 13 and ring- 2 and is of sach a shape that after unscrewing bolt 6 the arrn of the hoe can easily beren/loved when a small turning motion of the arni around pin 13 is executed. i
rllhe working edge o't each flat arni is ci convex curvature and fitted at the end projecting,` beyond the innerplates d with a hoe 17 beveled its sides and standing bach in relation with the curved edge.
Preferably the driving axle l is provided with a plurality oi spit rer-lilr-e unitsiiorined by the hoes and airanged on the axle, each nnit consisting ol three hoes connected to the plates in the manner shown in Figs. l, 2 and 3. Advantageonsly the arms ot the adjacent units are turned against each other. The separate units are threaded on the drivingl axle spaced by bushings 15 and then pressed together by nuts 16, the ring;- 2 havingr such a thickness that sulicient clearance is provided to allow an unrestricted movement of the inner plates el inside the enter plates The ring 2 serves atethersaine time to center the inner plates fi.
A great advantage of the di,g'ginp ,1 apparatus shown consists in the tact that all three circular springs 8 taire part simultaneously in producing the momentary resiliency el any single working' hoe. This eirciunstance allows ci using single circular springs of comparatively srnall dimensions and of placing' them near the driving; axle 1. The great advantage results thereof that the lengths of the arins of the hoes used for active worlr are considerably7 increased. The fastening` oi the hoes gives a goed ratiov between the length of the iixed part and the free'part of thc hoe arms on which their lateral elasticity depends. increased lateral elasticity of the hoes is of great iniportance when stones or other objects cans-A ing a considerable resistance are struck by the hoes.
