Abstract: A rotor link attached to a debarking cylinder. An open link is attached to the rotor link and a chain is attached to the open link. The open link must be rotated forward in the direction of rotation of the debarking cylinder so that a flat area of the rotor link is presented adjacent the open area of the open link. This makes it less likely that the link will be disengaged by random movement of the chain during a debarking operation. Thus, individual chains can be removed without removal of the attachment rod and all the chains on the cylinder. A second chain may be attached to the open link through a similar series of translational and rotational movements.

Abstract translation: 连接到剥皮滚筒的转子连杆。 连接到转子连杆上的开放连杆，链条连接到开放连杆上。 开放连杆必须沿着剥皮滚筒的旋转方向向前旋转，使得转子连杆的平坦区域邻近打开连杆的开口区域呈现。 这使得链条在剥皮操作期间通过链条的随机运动而不太可能脱离。 因此，可以在不移除附接杆和圆柱体上的所有链条的情况下移除单个链条。 第二链可以通过类似的一系列平移和旋转运动连接到开放链节上。

Abstract: A portable support structure defines a generally horizontal path along which an elongated log may be longitudinally shifted and mounts an upwardly opening tree trunk supporting and guiding crotch structure therefrom as well as a pair of curvilinear limb stripping blades mounted for movement toward and away from each other and defining a tree trunk encircling cutting opening therebetween generally coaxial with the aforementioned path. Log presence sensing structure is spaced along the path from the blades and mounted from the support structure for movement between upper and lower limit positions and resiliently yieldable motion transmitting structure is operatively connected between the log pressure sensing structure and the blades for swinging the latter toward and away from each other responsive to down and up movement, respectively, of the log pressure sensing structure.

Abstract: A combination log debarking, log chipping unit having a debarking apparatus and a chipping apparatus mounted on a common chassis, the two apparatus are aligned for conveying logs from the debarking apparatus to the chipping apparatus. The two apparatus are separated by a space of about 6-10 feet to permit loose bark to be removed from the logs and thereby avoid bark contamination of the chip. A conveyor system between the two apparatus guides and conveys logs to the chipper. A single power source enables control over the feeding of the logs to synchronize log feeding with the chipper's chipping capability. A loader over the debarking apparatus provides convenient loading of the logs into the debarker. The power source and controls for the various operating components are all under the common control of the loader operator.

Abstract: This invention relates to a tree pruning machine comprising a frame in a cutting unit having a first member mounted to a body having wheels elevating vertically, and a second member projecting from the top of the first member forwardly in an ascent gradient and forming a recess at the front side, the first member having drive wheels mounted on the lower portion thereof and driven by an engine, and a saw chain rotated by the engine through the drive wheels along the frame formed by the first and second members for cutting a branch of a standing tree. Furthermore, the tree pruning machine includes a branch sensing member telescopically provided in the lengthwise direction of the second member of the cutting unit, the front of the sensing member projecting forwardly of the second member for temporarily stopping the drive of the pruning machine toward the upward direction of the standing tree. The sensing member of the pruning machine can reliably sense the branch to be contacted with the top of the cutting unit and the sensing member does not abstruct the pruning machine from climbing the standing tree. Thus, the pruning machine can climb the standing tree without fail even when the cutting unit makes contact with the branch of the tree.
