Abstract
Abstract ABSTRACT OF THE DISCLOSURE A tree processing unit having a base and a boom with a front end and a back end, extending through the base. Means are provided for moving the boom through the base the base has means for gripping a tree at its butt end. Means are fixed on the front end of the boom for gripping and debranching the tree, and for cutting the top of the tree. The unit is adapted to be mounted on known motorized equipment so the unit can be carried and manoeuvred and provided with power.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
305 words
A tree processing unit to be used in combination with a conventional hydraulically operated, motorized equipment including a main body and a base support pivotably mounted on and extending up from said body, said unit comprising: an elongated, tubular mounting base; means on the mounting base for detachably connecting the same to the base support of the equipment; a rigid, elongated tubular boom passing entirely through the mounting base, said boom having a front end and a back end both provided with at least one upright support; means for slidably guiding the boom through the mounting base; motor means on the mounting base for moving the boom through the latter in either direction; at least one vertical, supporting post mounted on themoun-ting base, said supporting post carrying at its top end at last one roller; at least one tension cable extending between the top ends of the upright supports at both ends of the boom for strengthening the latter, said cable being supported and riding over the roller at the top end of the supporting post; means fixed on the front end of the boom for gripping and debranching a felled tree; other means fixed on the front end of the boom for cutting the top of the tree; and means fixed on the mounting base for gripping the tree adjacent its butt end, whereby the felled tree is picked up adjacent its butt end by tilting the base support, moving the boom through the mounting base towards the tree and manoeuvring the gripping means fixed on the front end of the boom; the tree is then clamped adjacent its butt end by the gripping means fixed on the mounting base after having rearwardly moved the boom, and lastly, the tree is debranched and its top end is cut by moving again the boom forwards.
Claim 2
Dependent Claim
305 words
A tree processing unit to be used in combination with a conventional hydraulically operated, motorized equipment including a main body and a base support pivotably mounted on and extending up from said body, said unit comprising: an elongated, tubular mounting base; means on the mounting base for detachably connecting the same to the base support of the equipment; a rigid, elongated tubular boom passing entirely through the mounting base, said boom having a front end and a back end both provided with at least one upright support; means for slidably guiding the boom through the mounting base; motor means on the mounting base for moving the boom through the latter in either direction; at least one vertical, supporting post mounted on themoun-ting base, said supporting post carrying at its top end at last one roller; at least one tension cable extending between the top ends of the upright supports at both ends of the boom for strengthening the latter, said cable being supported and riding over the roller at the top end of the supporting post; means fixed on the front end of the boom for gripping and debranching a felled tree; other means fixed on the front end of the boom for cutting the top of the tree; and means fixed on the mounting base for gripping the tree adjacent its butt end, whereby the felled tree is picked up adjacent its butt end by tilting the base support, moving the boom through the mounting base towards the tree and manoeuvring the gripping means fixed on the front end of the boom; the tree is then clamped adjacent its butt end by the gripping means fixed on the mounting base after having rearwardly moved the boom, and lastly, the tree is debranched and its top end is cut by moving again the boom forwards.
Claim 3
Dependent Claim
72 words
A unit as claimed in claim 1 wherein said motor means for moving the boom through the mounting base comprises a pair of parallel drive chains mounted on the top of the boom and extending over its length, a pair of drive sprockets mounted on the mounting base above the boom and over which the chains are guided, and a motor for operating the sprockets to drive the boom in either direction.
Claim 4
Dependent Claim
93 words
A unit as claimed in claim 2, wherein said means for slidably guiding the boom through the mounting base comprises a set of guide rollers at each end of the mounting base bearing on the bottom of the boom, a set of guide rollers at each end of the mounting base bearing on the top of boom, a guide roller at each end of the mounting base bearing on one side of the boom, and a guide roller at each end of the mounting base bearing on the other side of the boom.
Claim 5
Dependent Claim
72 words
A unit as claimed in claim 3, wherein the gripping and debranching means fixed on the front end of the boom, includes a pair of movable, opposite jaw members extending down from the front end of the boom, said jaw members being longitudinally offset from each other and hydraulically operated by hydraulic lines extending from the motorized equipment near the vicinity of the mounting base, to the front end of the boom.
Claim 6
Dependent Claim
45 words
A unit as claimed in claim 4, wherein the gripping and debranching means fixed on the front end of the boom inclu-des an anvil surface facing downwardly, the anvil surface cooperating with the movable jaws, when moved toward each other, to grip a tree therebetween.
Claim 7
Dependent Claim
25 words
A unit as claimed in claim 5, wherein the anvil surface has a leading edge for cooperating with the jaw members to debranch the tree.
Claim 8
Dependent Claim
49 words
A unit as claimed in claim 5, wherein the cutting means comprise a cutting member adjacent the anvil sur-face and hydraulic means fed by the hydraulic lines extending from the motorized equipment for moving the cutting member toward the anvil surface to cut the top of the tree therebetween.
Claim 9
Dependent Claim
56 words
A unit as claimed in claim 4, 5 or 6, including means for connecting the jaw members to a common block mounted for vertical sliding movement, and hydraulic means fed by the hydraulic lines extending from the motorized equipment, for moving the block up or down to move the jaws toward or away from each other.
Claim 10
Dependent Claim
95 words
A unit as claimed in claim 7, wherein the hydraulic lines connected to the gripping and debranching means and to the cutting means fixed on the front end of the boom, extend externally from the motorized equipment, near the vicinity of the mounting base, to the back end of the boom and internally through boom, from the back end to the front end of the same, said hydraulic lines extending externally between the motorized equipment and the back end of the boom being suspended from at least one hanger slidably mounted on the tension cable.
Claim 11
Dependent Claim
89 words
A unit as claimed in claim 1, 2 or 3, wherein the gripping means located on the mounting base comprises a backing member extending down from one side of the mounting base said backing member providing an inner, downwardly opening pocket to receive the trunk of the tree to be processed, a jaw member extending down from the other side of the mounting base, and hydraulic means on the mounting base to grip a tree trunk therebetween, said hydraulic means being fed by hydraulic lines from the motorized equipment.
Claim 12
Dependent Claim
38 words
A unit as claimed in claim 1, 2 or 3, including abutment means located on the mounting base adjacent the gripping means located on said mounting base, for receiving the butt end of the tree to be processed.
