Abstract: A stump grinder has a grinding arm that durably mounts a rotatable grinding wheel by securing the drive shaft of a motor to the grinding wheel such that a pair of bearings within the motor support one side of the grinding wheel and by supporting the other side of the grinding wheel with a stub shaft received within a third bearing. The grinding arm is laterally offset on the frame of the stump grinder to have a swing angle that is not symmetrical relative to the width of the frame, but with the swing angle starting at one side of the frame and then traversing across substantially the entire width of the frame to improve the ability of the operator to see the grinding wheel. A single joystick is movable in orthogonal directions corresponding to desired up and down and side-to-side pivoting motions of the grinding arm. The joystick includes a depressible trigger for starting and stopping the operation of the grinding wheel.

Abstract: A multi-axis controlled self-climbing tree trimmer used for shaping and severing peripheral growth from a tree is provided herein. The trimmer typically includes a structural segment hinged together to form a rigid chassis that surrounds a tree trunk climbing segment and a trimming portion. The climbing portion is retained within the structural segment in the form of a number of inward-extending carriages containing one or more rollers for gripping the tree trunk during climbing, and the trimming portion may include a rotatable split ring gear containing centrifugally rotating trimming blade members and/or a cutting tool on a positionable arm. When rotated, the blade members unlatch and pivot, into the trunk of the tree to effect controlled trimming. The system may utilize a multi-axis control system that uses linear interpolation, circular interpolation and coordination of all axes to enable the trimmer to follow an XYZ contour selected by a user.

Abstract: A holding device and method for engaging a work piece to route an end thereof. The device includes parallel first and second side plates and first and second clamping plates; where the clamping plates are positioned between the side plates. A connector member connects all the plates together. An activator assembly is engaged with the plates and, in a first instance, moves the clamping plates laterally toward each other and in a second instance moves them laterally away from each other. When moved toward each other, each clamping plate contacts one of the elongated sides of the work piece and the work piece is thereby clamped between the clamping plates. A clamping element extends downwardly from the connector member to contact the work piece. The holding device is usable in two different orientations to enable routing of the end face or second face of the work piece.

In response to the edge cutter head and the at least one edge of the material being brought into cutting contact and moved relative to each other, a resulting portion of the at least one edge of the material is distressed.

Abstract: A radius cutting platform assembly includes an assembly housing; a pivot mechanism carried by the assembly housing, the pivot mechanism adapted to pivotally attach the assembly housing to a support surface; a generally elongated router guide carried by the assembly housing, the router guide selectively adjustable with respect to the assembly housing along a linear axis; a router base having a router bit opening carried by the router guide; and at least one set of distance markings on the router guide, the distance markings indicating distance between the router bit opening in the router base and the pivot mechanism.

Abstract: The invention relates to a security element of at least one thin layer element in form of a multi-layer composition, capable of interference. The multi-layer composition, capable of interference, consists of at least one reflecting layer, at least one partially transmitting layer and at least one dielectric layer arranged between these layers. According to the invention the security element comprises in a first region a multitude of gaps in the reflecting layer and in a second region at least one gap or a multitude of gaps in the partially transmitting layer. Herein the second region is arranged at least partially within the first region and the total area of the second region, which is at least partially arranged within the first region, is smaller than the total area of the first region. Therefore the security element displays, when viewed from the partially transmitting layer, a different appearance in top view than in transmission view.

Abstract: A log/tree chipper having an infeed with a roller member, such as a sprocket or pulley, guides a chain has at least one lug in the roller member, such lug extending above the outer surface of the chain and above a feed table.
