Abstract
Abstract A self-propelled delimbing machine includes a horizontal Tshaped frame having a length suitable for supporting full-length trees. First and second ground wheel assemblies are respectively supportingly connected to the opposite ends of the head portion of the frame and a third ground wheel assembly is supportingly connected to the leg portion of the frame at a location spaced more than half the length of the leg portion from the head portion. The leg portion of the frame is divided into first and second sections of approximately equal length, the first section extending from the head portion of the frame and the second section being connected in end-to-end relationship to the first section by a vertical hinge joint. The hinge joint is locked to prevent pivoting when the machine is in a delimbing or working mode and is unlocked to permit the second section to be pivoted to a folded position alongside the first section to shorten the delimbing machine for transport. The pivoting of the second section on the hinge joint is accomplished by operation of the third wheel assembly, which includes drivable and steerable wheels. Stabilizer leg means are mounted on the head portion of the frame and are selectively operated to engage the ground and give added stability to the vehicle when the second section of the leg portion of the frame is being folded.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
94 words
In a mobile delimbing vehicle of the type including an elongate, horizontal frame for supporting tree stems and steerable, driven ground-engaging means supporting said frame, the improvement comprising: said frame including at least first and second separate sections; connecting means joining said sections for permitting said second section to be moved between an extended working position in end-to-end alignment with said first section and a folded transport position alongside said first section; and power means connected at least to said second section for selectively moving the second section between said working and transport positions.
Claim 2
Dependent Claim
94 words
In a mobile delimbing vehicle of the type including an elongate, horizontal frame for supporting tree stems and steerable, driven ground-engaging means supporting said frame, the improvement comprising: said frame including at least first and second separate sections; connecting means joining said sections for permitting said second section to be moved between an extended working position in end-to-end alignment with said first section and a folded transport position alongside said first section; and power means connected at least to said second section for selectively moving the second section between said working and transport positions.
Claim 3
Dependent Claim
15 words
The invention defined in claim 1 wherein said driven ground-engaging means includes said power means.
Claim 4
Dependent Claim
101 words
A mobile delimbing vehicle comprising: a wheel-supported power unit; a first elongate generally horizontal delimbing platform section connected at one end to said power unit; a second elongate generally horizontal delimbing section; vertical hinge means interconnecting said first and second platform sections for permitting said second section to be swung between an extended working position in longitudinal alignment with said first section and a folded transport position alongside said first section; and steerable and drivable ground-engaging means connected to said second section adjacent said hinge means for powering said second section about said hinge means between said working and transport positions.
Claim 5
Dependent Claim
101 words
A mobile delimbing vehicle comprising: a wheel-supported power unit; a first elongate generally horizontal delimbing platform section connected at one end to said power unit; a second elongate generally horizontal delimbing section; vertical hinge means interconnecting said first and second platform sections for permitting said second section to be swung between an extended working position in longitudinal alignment with said first section and a folded transport position alongside said first section; and steerable and drivable ground-engaging means connected to said second section adjacent said hinge means for powering said second section about said hinge means between said working and transport positions.
Claim 6
Dependent Claim
161 words
In a mobile delimbing machine of the type for delimbing full-length trees and including a horizontal platform of substantial length for supporting felled trees, an operator''s station located adjacent one end of the platform, first and second driven ground-engaging means respectively mounted at said one end and intermediate the ends of said platform for movement between first and second positions for respectively advancing the machine perpendicular and parallel to its length, and said platform including an adjacent and a remote section, relative to said operator''s station, and releasable joint means interconnecting said adjacent and remote sections, the improvement wherein said releasable joint means includes a vertical pivot means permitting said remote section to be moved between an extended working position in longitudinal alignment with the adjacent section and a folded transport position alongside said adjacent section; and said second ground-engaging means being mounted to the remote section and being operable for moving said remote section between said working and transport positions.
Claim 7
Dependent Claim
161 words
In a mobile delimbing machine of the type for delimbing full-length trees and including a horizontal platform of substantial length for supporting felled trees, an operator''s station located adjacent one end of the platform, first and second driven ground-engaging means respectively mounted at said one end and intermediate the ends of said platform for movement between first and second positions for respectively advancing the machine perpendicular and parallel to its length, and said platform including an adjacent and a remote section, relative to said operator''s station, and releasable joint means interconnecting said adjacent and remote sections, the improvement wherein said releasable joint means includes a vertical pivot means permitting said remote section to be moved between an extended working position in longitudinal alignment with the adjacent section and a folded transport position alongside said adjacent section; and said second ground-engaging means being mounted to the remote section and being operable for moving said remote section between said working and transport positions.
