My invention relates to a machine for thoroughly stirring and pulverizing the earth, to prepare it for seeding, by means of rotary scari- Iiers or pulverizers.
The invention consists in a rotary scarilier composed of a skeleton frame, around which are spirally wound two or more cutting-strips attached to arms projecting from the skeleton frame, and set at an angle to the axis, so as to be dishing. It also consists in the combination of a jointed shaft with two of these rotary scarilers mounted thereon, whereby their angle to each other may be adjusted. It also consists in the combination lof a seeding device with the rotary scariers and special devices for operating the former by the latter at l pleasure; and it further consists -in various devices and combinations of devices, as -will be hereinafter fully set forth.
In the drawings, A represents a simple frame, to which is attached a tongue, B. From each end of the frame depend hangers a, in which is supported a shaft, G. This shaft is made in two parts,- the inner ends of which are halved, as shown in Figs. 4 and 5 of the drawings, and pivoted together, so that the shaft may be moved backward and forward, the bearings in the hangers a being sufciently large to accommodate this movement. An angular-braced hanger, D, is also attached to the lower side ofthe tongue, the lower end of which .is constructed with a recess, d, as
shown in Fig. 3 ofthe drawings, within which is placed the inner ends of the two parts of the shaft C, and through which the bolt passes which unites them. rlhe hanger D is attached to the tongue B by two bolts, oneof which, b, passes through a slot, d1, in the hanger, and the other of which, b', is inserted in any one of a series of holes, d2, in the upper arm of the hanger. Both bolts pass through the tongue, and are provided with screw-nuts for tightening them up.
It is. evident that, by means of these devices, the hanger D may be adjusted back and forth on the tongue, thereby adjusting in a similar manner the jointed shaft U. The scarifiers E are constructed of a skeleton cylindrical frame composed of two disks, E', joined Vtogether by cross-.bars e, attached to their edges, each of which are provided with a series of lugs or short arms, e. These lugs or arms e `are inclined or set at an angle to the bars e, as shown in Figs. l and 9 of the drawings.
Narrow bands or strips of metal F are wound spirally around this skeleton frame. These spiral strips should be two or more in number, and are fastened by rivets` to the arms e. The strips F are set with one edge,f, projectin g outward beyond the arms e'. The edge f is sharpened or beveled, and as the arms e' are inclined, as above described, the strips F attached thereto will stand in a dishing position to the axis of the cylinders, around which they are wound. The origin of the several spirals is at different points around the cy1in der, so that there is alwaysja free space be-y tween the end of vone spiral and the nearest turn of the next one.
The disks E are perforated to receive the shaft G, on each division of which one of the spiral scariers is mounted, the joint in the shaft being between them. It is evident,
therefore, that the adjustment of the shaft described above will also adjust the scaritiers, so that they may stand directly in line with lSheetS-Sheet 1.. J. R. BROWN, decd. G. D. OWEN andL. SHARPE, Executors.
