Abstract
Abstract A rotary cultivator assembly comprising a support having an attachment extremity and a shaft extremity with a bearing assembly mounted on the shaft. The bearing assembly has a predetermined cross section and mounts tubular hubs in varying lengths in a cantilever manner to permit the mounting of a variable number of spider units or cultivator wheels on the same with the entire assembly being held in assembled relationship by means of an end cap and a flange on the bearing assembly and tie bolts extending therebetween.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
182 words
A rotary cultivator assembly comprising, an L-shaped support frame including an attachment means near one extremity of the same and a transversely extending shaft at the other extremity of the same, a hub assembly including elongated bearing means positioned on the shaft of the support frame and journaled thereon, said bearing means having polygonal external peripheral surfaces, an elongated hollow hub member having the same polygonal cross section and fitted over the polygonal shaped peripheral surfaces of the bearing means and extending beyond the same, a plurality of cultivator spiders each having a central aperture with the same polygonal outline fitted over the hub member and mounted thereon and spaced in side-by-side relationship, spacer means positioned on the hub member and between the rotary cultivator spiders to space the same, and means securing the cultivating spiders and spacers together with the hub member to the bearing means, said bearing means including a flange against which the hub member abutts when positioned on the bearing means and to which the means securing the cultivator spiders and hub member to the bearing means attaches.
Claim 2
Dependent Claim
182 words
A rotary cultivator assembly comprising, an L-shaped support frame including an attachment means near one extremity of the same and a transversely extending shaft at the other extremity of the same, a hub assembly including elongated bearing means positioned on the shaft of the support frame and journaled thereon, said bearing means having polygonal external peripheral surfaces, an elongated hollow hub member having the same polygonal cross section and fitted over the polygonal shaped peripheral surfaces of the bearing means and extending beyond the same, a plurality of cultivator spiders each having a central aperture with the same polygonal outline fitted over the hub member and mounted thereon and spaced in side-by-side relationship, spacer means positioned on the hub member and between the rotary cultivator spiders to space the same, and means securing the cultivating spiders and spacers together with the hub member to the bearing means, said bearing means including a flange against which the hub member abutts when positioned on the bearing means and to which the means securing the cultivator spiders and hub member to the bearing means attaches.
Claim 3
Dependent Claim
43 words
The rotary cultivator assembly of claim 1 in which the polygonal cross section of the hub member and the apertures in the rotary cultivating spiders is square with the bearing means having a square external peripheral surface for mounting the hub member thereon.
Claim 4
Dependent Claim
59 words
The rotary cultivator assembly of claim 1 in which the means securing the cultivator spiders with the spacers therebetween and the hub member to the bearing means includes an end cap positioned over the end of the hub member and with bolt means extending from the end cap to the flange of the bearing means and being secured thereto.
Claim 5
Dependent Claim
39 words
The rotary cultivator assembly of claim 3 in which the plurality of rotary cultivator spiders at the central openings therein have notches to pass the bolt means extending between said flange of the bearing means and the end cap.
Claim 6
Dependent Claim
47 words
The rotary cultivator assembly of claim 4 in which the elongated bearing means includes a bearing assembly having incorporated therewith Said flange of the bearing means and spacer means with the spaced-bearing mounting structures having individual bearings therein journaling the bearing assembly on the translationally extending shaft.
Claim 7
Dependent Claim
57 words
The rotary cultivator assembly of claim 1 and including a flange portion connected to the L-shaped support frame near said one extremity and extending parallel to said shaft with a plurality of mounting apertures therein adapted to mount metallic cleaning rods extending from said apertures and connected thereto and between the spiders journaled on the hub assembly.
Claim 8
Dependent Claim
63 words
The rotary cultivator assembly of claim 1 in which the attachment means near the extremity of the L-shaped support frame includes a cylindrical hub with a bolt receiving aperture therethrough and a serrated surface encircling the aperture and adapted to co-operate with a similar serrated connecting part to adjustably position the support frame at varying angular positions with respect to a supporting structure.
Claim 9
Dependent Claim
142 words
A rotary cultivator assembly comprising, a cantilever type support having attachment means at one extremity and a supporting shaft at the other extremity, elongated bearing means mounted on the shaft, a hub member slidably positioned over the bearing means and drivingly connected thereto to be journaled on the shaft, and means including a plurality of rotary cultivating spiders and spacers telescopically fitted over the hub member and mounted thereon for rotation therewith, said last named means including means for holding the hub member and the rotary cultivating spiders in assembled relationship on said bearing means, said means having the plurality of rotary cultivating spiders including the plurality of spiders with spacers therebetween fitted over the hub member in non-rotative relationship therewith and bolt means extending between the bearing means and a retaining flange abutting the hub member and one of the spiders.
Claim 10
Dependent Claim
142 words
A rotary cultivator assembly comprising, a cantilever type support having attachment means at one extremity and a supporting shaft at the other extremity, elongated bearing means mounted on the shaft, a hub member slidably positioned over the bearing means and drivingly connected thereto to be journaled on the shaft, and means including a plurality of rotary cultivating spiders and spacers telescopically fitted over the hub member and mounted thereon for rotation therewith, said last named means including means for holding the hub member and the rotary cultivating spiders in assembled relationship on said bearing means, said means having the plurality of rotary cultivating spiders including the plurality of spiders with spacers therebetween fitted over the hub member in non-rotative relationship therewith and bolt means extending between the bearing means and a retaining flange abutting the hub member and one of the spiders.
Claim 11
Dependent Claim
37 words
The rotary cultivator assembly of claim 1 in which the elongated bearing means is a mounting frame with a pair of spaced bearings therein attached to the shaft and journaling a portion of the bearing means thereon.
Claim 12
Dependent Claim
48 words
The rotary cultivator assembly of claim 1 in which the driving connection between the bearing means and the hub member is provided by a polygonal external peripheral surface on the bearing means and a similar interior surface on the hub member to telescopically fit over the bearing means.
Claim 13
Dependent Claim
44 words
The rotary cultivator assembly of claim 10 in which the cantilever type support includes attachment means at one extremity having a mounting aperture therethrough and a serrated adjustment surface surrounding the mounting aperture and adapted to adjustably position the same on a supporting part.
