I form of construction, as illustrated in the drawing, comprises two

end discs

10 and 11 and an intermediate disc support a draft bar a 10 and 11 and on the opposite faces of the intermediate disc 12. Theslots "are thus arranged in the same planes so asto accommodate and receive the ends of cultivator "blades of the cultivator blades 16-17 isprovided neachi end; with a notch18a'nd a co-operatlng'securing tongue 19,;the notch 18 being adapted and arranged to fit overthe correshown, on theinner faces of the end. discs 16 and 17-, which will thus be arranged in radially disposed, oppositelyinclinedrelavrtionshipiwith each other, as shown.

The specific form and arrangement of parts is a simple and effective one for the purpose.

lVhile I have illustrated and described the preferred form of construction for carrying the invention into eiiect, this is capable of variation and modification without departing from the spirit of the invention. I therefore do not wish to be limited to the precise details disclosed, but would desire to avail myself of the various variations and modifications as fall within the scope of the appended claims.

Having thus fully described my invention, What I claim as-neW and desire to secure by Letters Patent is:

1. A rotary member for cultivators comprising end discs and an intermeoiate disc. said end discs being provided with oppositely inclined slots in their peripheries and said intermediate disc with alternating oppositely inclined co-operatin slots in its periphery: and cultivator blades positioned in said slots.

2. A rotary member for cultivator-s com prising end discs and an intermediate d sc, said end discs being provided with oppositely inclined slots in their peripheries and said intermediate disc with alternating oppositely inclined co-operating slots in its periphery;'

securing ribs on the inner face of said end discs and on both faces of said intermediate disc; and cultivator blades positioned in said slots, each blade being provided at each end with a notch and locking tongue to fit over and engage the corresponding locking rib.

A rotary member for cultivators comprising end discs and an intermediate disc, said end discs being provided with oppos inclined slots in their peripheries and intermediate disc with alternating positely inclined co-operatim periphery; securing ribs on the inner face of said end discs and on both faces of said intermediate disc; and cultivator blades positioned in said slots, each blade being provided at each end with a notch and locking tongue to fit over and engage the corresponding locking; rib; a central trunnion v bolt member extending centrally through all the said discs; and separate scouring bolts attaching each disc with its adjacent disc.

In. Witness whereof, I have hereunto set my hand this 14 day of March, 1929.

JOHN F. ZEILINGER.
