Abstract
Abstract A hub is carried by a support turnable about an upright axis and in turn provides a plurality of arms which radiate from it and carry at their respective outer end portions sets of parallel tines which project downwardly toward the ground. The tines are so mounted that each set turns about a vertical and a horizontal axis and when the arms turn with their hub, each set extends during one portion of the circular path in which it moves, substantially tangential to this path and in this portion has a vertical component of movement relative to the path about the respective horizontal axis.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
164 words
In an agricultural machine, in combination, support means spaced upwardly from the ground on which said machine is supported; a hub carried by said support means and turnable about an upright axis; a plurality of angularly spaced arms carried by and extending outwardly from said hub for turning in a circular path, said arms having outer free end portions; a plurality of sets each composed of a carrier mounted on said outer free end portion of a respective arm for turning movement about a substantially vertical axis, and a plurality of substantially parallel tines carried on said carrier and projecting downwardly toward the ground; and control means for effecting displacement of each of said carriers about said substantially vertical axis from a raking position to a depositing position in which said carriers extend substantially tangentially to said path, and for effecting at the same time upward displacement of the respective arm about a horizontal axis so that said tines move away from The ground.
Claim 2
Dependent Claim
164 words
In an agricultural machine, in combination, support means spaced upwardly from the ground on which said machine is supported; a hub carried by said support means and turnable about an upright axis; a plurality of angularly spaced arms carried by and extending outwardly from said hub for turning in a circular path, said arms having outer free end portions; a plurality of sets each composed of a carrier mounted on said outer free end portion of a respective arm for turning movement about a substantially vertical axis, and a plurality of substantially parallel tines carried on said carrier and projecting downwardly toward the ground; and control means for effecting displacement of each of said carriers about said substantially vertical axis from a raking position to a depositing position in which said carriers extend substantially tangentially to said path, and for effecting at the same time upward displacement of the respective arm about a horizontal axis so that said tines move away from The ground.
Claim 3
Dependent Claim
52 words
In an agricultural machine as defined in claim 1, said control means comprising a cam disc surrounding and eccentric to said upright axis, and linkage means linking said cam disc with the respective carriers for imparting to the latter during turning of said hub a swivel movement about the respective vertical axis.
Claim 4
Dependent Claim
41 words
In an agricultural machine as defined in claim 1, said arms having inner portions adjacent said hub; and further comprising connecting means connecting said inner portions with said hub for performing movement in a curved path during rotation of said hub.
Claim 5
Dependent Claim
39 words
In an agricultural machine as defined in claim 1, said control means comprising a cam disc surrounding said upright axis and operatively connected with said sets of tines for imparting thereto said turning movements about the respective vertical axes.
Claim 6
Dependent Claim
23 words
In an agricultural machine as defined in claim 1, and further comprising a three-wheeled chassis for said support, located within said circular path.
Claim 7
Dependent Claim
34 words
In an agricultural machine as defined in claim 5, wherein one of the wheels of said chassis is a guide wheel turnable about an axle which parallels the common axle of the remaining wheels.
Claim 8
Dependent Claim
31 words
In an agricultural machine as defined in claim 5, said machine further having a guide pole connected with said support for pivotal displacement about an at least substantially horizontal pivot axis.
Claim 9
Dependent Claim
41 words
In an agricultural machine as defined in claim 4, said control means further comprising crank means associated with said cam disc and the respective arms for swivelling the latter about their respective longitudinal axes in response to turning of said hub.
