Abstract: A plurality of limbs or the like are secured together, to form a limb bundle (B). The limbs are positioned in a space defined laterally between a pair of posts (20, 24) on one side of a frame (12) and a second pair of posts (22, 26) on the opposite side of the frame (12). A windless (44) is supported at the upper ends of the posts (20, 24). A cable (54) extends from the windless (44) either downwardly and around the girth of the limb bundle (B), and then hooks on itself, to form a noose around the limb bundle (B), or it extends from the windless (44) down to and around a pulley (76), then upwardly and over a mid portion of the limb bundle (B'), and then down to a dead end connection (70) at a lower portion of the frame (12). In either case, tightening of the cable (54, 54') imposes a squeezing force on the limb bundle (B).

Abstract: A cutting tool assembly for a log debarker. A cutting tool is provided having an elongated leading cutting edge and a key member. The key member fits into the load carrying slot portion of the head of the tool shaft, and the tool is then secured to the tool shaft head with a plurality of retainer bolts. The tool shaft head is machined at an angle of generally five degrees relative to the axis of an incoming log so as to slant the orientation of the tool and its leading edge. Thus, an incoming log will impact initially a central location of the tool and not its full length. A tensioning device places the tool shaft in tension about a pivot axis and the outermost tip of the tool continually points towards the center line of an incoming log as the tool shaft pivots about this pivot axis. Every other tool is extended a slight distance further towards the incoming log than the adjacent tools by an extension spacer or washer to further reduce the shock loading previously encountered.

Abstract: A wood shaper utilizing multiple vertical cutting shaper assemblies mounted on the opposed end portions of a horizontal shaft. Each shaper assembly has, to the opposite sides thereof, an elongate guide fence and an elongate finger guard selectively adjustable relative to each other and the shaper assembly therebetween. Each guide fence mounts a pair of horizontal support bars for independent vertical adjustment relative to each other. The support bars align with the intake and discharge sides of the associated shaper assembly. As a variation, a second commonly driven horizontal shaft can be provided parallel to the first shaft. The second shaft will mount, at one end thereof, a third vertical shaper assembly received between an elongate guide fence with dual support bars and a laterally adjustable finger guard.

Abstract: For severing long workpieces, in particular pipes of metal material, especially at high temperatures, in a normal plane relative to the axis at an arbitrary site with the aid of a metal-cutting tool, a workpiece is firmly clamped and at a standstill, while the tool is guided in an interrupted cut around the workpiece with continuous radial advancement. The tool remains in engagement with the workpiece over only a portion of its path, which is effected by way of example in that the central circling of the cutting movement has superimposed upon it an eccentric planetary movement, so that the line of cutting is not a continuous circular line. In an apparatus for performing this method, a knife head (3) equipped with cutting knives (5) is seated on the end toward the cut of a hollow working shaft (2) rotating in a housing (1). A hollow control shaft (7) is preferably supported centrally in the hollow working hsaft (2) carrying the knife head (3).

Abstract: A holder for embossing items of irregular cross-section is utilized in an embossing machine which has a pair of opposed platens with embossing dies mounted thereon. The holder includes a support plate positioned between the platens and having a central opening formed therein for receiving the die mounted on a first one of the platens. A pair of support blocks extends from the support plate toward the second platen on opposite sides of the opening and supports an article to be embossed over the opening. A plurality of guide posts extend from the first platen through apertures formed in the support plate and helical biasing springs encircle the guide posts to space the support plate and the article from the first die. As the second platen is moved toward the first platen, the second die engages the article and moves the article and the support plate against the biasing means to engage the article with the first die. Thus, equal pressure is applied to the article by the first and second dies.

Abstract: A portable log splitter having a frame supported adjacent to its rear and front ends by cranked axle structure and a stand interconnected with the axle for raising and lowering of the rear and front ends in unison and in a substantially level mode so as to enable the splitter device to more readily handle ground-supported logs. The splitter is rockable about a fore-and-aft axis through a range including an upright position and a generally horizontal position so as to achieve splitting in planes within that range. Raising and lowering of the frame increases the ability of the splitter to make horizontal splits at relatively low levels. The stand is disconnectible from the axle means for retraction clear of the ground to condition the frame for towing behind a towing vehicle.
