Abstract
Abstract A tree processing machine including an attachment therefor to collect and unload logs discharged from the processing units on the machine. The tree collecting and unloading is a tree-handling off-feed assembly detachably secured either to the undercarriage of the vehicle or to a platform pivotally mounted on the carriage for movement with the processing units or pivotally mounted on the undercarriage to slew about a vertical axis independent of slewing of the platform on which the processing units are mounted. The off-feed assembly includes a pair of arcuate collecting arms in one form pivotally secured to the frame of the off-feed assembly so as to enable movement of the same when struck by an object during movement of the mobile tree processing machine. The off-feed mechanism further includes an operator''s station consisting of a cab providing an enclosure for the operator and a boom and grapple assembly pivotally mounted thereon or adjacent thereto such that an operator in the cab has a commanding view of logs collected on the arcuate arms and with suitable controls is able to manipulate the boom and grapple assembly to remove the collected logs. The arms which are provided for collecting the trees may also be referred to as a cradle and there may be one located on each of opposite sides of the frame with a movable deflector selectively directing processed logs into one or the other whereby cradle is being loaded, the other may be unloaded without interfering with the processing operation.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
167 words
A tree-processing processing machine which comprises in combination: a. a mobile base; b. at least one processing unit mounted on said base; c. a first boom and grapple assembly mounted on said base and disposed in a position for picking up felled trees and feeding the same to the processing unit mounted on said base; and d. a tree off-feed mechanism detachable secured to said machine, said off-feed mechanism including a frame, means for detachable securing said frame to the vehicle, means on the frame for supporting a plurality of logs stacked substantially in alignment on one another, a boom and grapple assembly pivotally mounted on said frame for slewing about a vertical axis, said boom and grapple including an extendible and retractable boom having a grapple suspended from adjacent the free end thereof and located at a position remote from logs collected on said log-supporting means and remote from the attachment of said frame to the vehicle and means for operating said boom and grapple assembly.
Claim 2
Dependent Claim
167 words
A tree-processing processing machine which comprises in combination: a. a mobile base; b. at least one processing unit mounted on said base; c. a first boom and grapple assembly mounted on said base and disposed in a position for picking up felled trees and feeding the same to the processing unit mounted on said base; and d. a tree off-feed mechanism detachable secured to said machine, said off-feed mechanism including a frame, means for detachable securing said frame to the vehicle, means on the frame for supporting a plurality of logs stacked substantially in alignment on one another, a boom and grapple assembly pivotally mounted on said frame for slewing about a vertical axis, said boom and grapple including an extendible and retractable boom having a grapple suspended from adjacent the free end thereof and located at a position remote from logs collected on said log-supporting means and remote from the attachment of said frame to the vehicle and means for operating said boom and grapple assembly.
Claim 3
Dependent Claim
28 words
A tree-handling attachment as defined in claim 1, including an operator''s station having an enclosure, for the operator, mounted on said frame adjacent said boom and grapple assembly.
Claim 4
Dependent Claim
24 words
A tree-handling attachment as defined in claim 2, including means pivotally mounting said enclosure on said frame for movement about a substantially vertical axis.
Claim 5
Dependent Claim
21 words
A tree-handling attachment as defined in claim 2 wherein said enclosure is located in an elevation vertically above the log-supporting means.
Claim 6
Dependent Claim
33 words
A tree processing machine as defined in claim 1 wherein said means on the frame for supporting a plurality of logs consists of at least two arcuate arms disposed in horizontal spaced relation.
Claim 7
Dependent Claim
39 words
A tree-handling attachment as defined in claim 5, including an end plate on at least one of said arms providing an end abutment for logs on the arms of maintain such ends of a stack of logs in alignment.
Claim 8
Dependent Claim
65 words
A tree-handling attachment as defined in claim 5, including means pivotally attaching each of said arms to said frame and further including stop means limiting pivoting of said arms in one direction to maintain the same directed outwardly from the frame in a load-receiving position, said pivot mounting permitting the arms to move upwardly to pass over obstacles encountered during movement of the mobile base.
Claim 9
Dependent Claim
21 words
A tree-processing machine as defined in claim 1 wherein said tree off-feed mechanism is secured to said base for movement therewith.
Claim 10
Dependent Claim
27 words
A tree processing machine as defined in claim 1 wherein said tree off-feed mechanism is pivotally mounted on said base for slewing about a substantially vertical axis.
Claim 11
Dependent Claim
45 words
A tree-processing machine as defined in claim 9 wherein said processing unit and first boom and grapple assembly are mounted on a common support pivotally mounted on said mobile base for slewing about a vertical axis independent of slewing motion of said tree off-feed mechanism.
Claim 12
Dependent Claim
36 words
A tree-processing machine as defined in claim 1 wherein said processing unit and first boom and grapple assembly are mounted on a common support pivotally mounted on said mobile base for slewing about a vertical axis.
Claim 13
Dependent Claim
21 words
A tree-processing machine as defined in claim 1, including deflector means for directing logs onto a cradle providing said log-supporting means.
Claim 14
Dependent Claim
38 words
A machine as defined in claim 12 wherein the directing means includes a pivotally mounted portion providing a gate and thereby selectively interrupting the flow of logs onto thE cradle while the previously deposited logs are removed therefrom.
Claim 15
Dependent Claim
43 words
A tree-handling attachment as defined in claim 13, including a further cradle mounted on said frame and located such as to receive the logs during said interruption of flow of the same onto the first-mentioned cradle whereby processed logs may be selectively sorted.
Claim 16
Dependent Claim
44 words
A tree processing machine as defined in claim 12 wherein said deflector includes members sloping in a direction from where the logs strike the same upon discharge from the last of one or more processing units in a direction toward the tree collecting means.
Claim 17
Dependent Claim
33 words
A tree-processing machine as defined in claim 15 wherein said deflector means includes a movable portion selectively directing processed logs as they are received to one of two or more different log-receiving locations.
Claim 18
Dependent Claim
46 words
A tree-handling attachment as defined in claim 16 wherein one of said log-receiving locations includes means for subsequently transferring the logs therein to one of the other log-receiving locations so as to provide a temporary storage for logs during processing while the latter is being cleared.
Claim 19
Dependent Claim
53 words
