The general objectof the invention is tocprovidelan improved rotary member for pulverizing Another object of the invention isto provide a novel soil .pulverizer blade and mounting therefor. 4 Other :objects and the advantages of this invention will be apparent from the 'following description taken in connection with the accompanying drawing,,wherein:
i Fig. .1 is an-elevation partly in section showing? details of the rotor.. v 1 j i Fig. 21s a fragmentary elevation showing de-.
Fig.3 is a diagramshowing the arrangement of cutting knives. 1 i l l Referring to the drawing by reference characters I have shown .my'invention as embodied in a soil-pulverizer which includes a bearing block 25which supports one end of a shaft 4|. This shaft 4| isvprovided' with a plurality of annular sheet steel spider members 42. Each of these membersis preferably made in two parts as shown in Fig. 1 and the two parts are secured together by straps or plates 43 and bolts or other fastening The sheet steel members 42 are clamped between flanges 45 and are held by bolts 46, as shown in Fig. 1. These flanges 45 are arranged on semi-cylindrical sleeves 41 which are provided with flanges 48 secured together by bolts 49 and the structure is such that the spider members 42 are rigidly held upon the shaft 4|.
The sheet steel spiders 42 are shaped to provide a rim portion 53 in the periphery of which are arrangedspaced slots 54. Two of the walls of these slots are preferably at right angles to each other while the third wall shown at 55, Fig. 2, is inclined towards the opposed wall. Blade supports are shown at 56:and include base portions 51 shaped to fit the slots 54 and an end portion 58 which overlays the adjacent part of the spider rim 53. portion 59 which engages the periphery of the rim portion 53 andare secured in place by bolts 60 which pass through the clamping members, the portion 53 and the endportions 58 'to hold Mounted upon the blade supports I show straight blades 6| which are held in place by bolts 6|. These blades are provided with opposed bev- Clamping members. 58" have an end it willbe'nnderstoodthat the number of setstof bladesmay be varied and the blades may be symmetrical or offset to. one side .ofthe tractor .de-

From the foregoing description. it will be apparent that I have invented a novel 'type of soil pulverizer which is highly eflicient in use, which can be economically manufactured, and which is not likely to get out of order.
Having thus described my invention, I claim:
1. In a soil pulverizer, a rotor comprising a pair of spaced disks, each of said disks having a series of peripheral notches therein, .blade supports having projecting portions thereon fitting said notches, and means to hold said blade supports in position. I l
mediate setC andtanother outer set D, although Inopera'tion, the rotor'is arranged at the .de-
members, said blade supports andsaid spiders.
3. For use in a soil pulverizer, a rotor compris-. ing a plurality of spaced spiders, each of said spiders havingka series of peripheral notches therein, blade supports having projecting portions thereon fitting said notches, clamping memberseng aging saidblade supports and fastening means passingthrough said clamping members, said blade supports and said spiders. y
4. In a soil pulverizer, a rotor shaft, a plu-- rality of pairs of semi-circularspiders. arranged about said shaft, meansto clampeach pair of semi-circularspiders together and to .the rotor shaft, blade supportsmounted on said spiders, I
