  • Patent number: 11672211
    Abstract: The improved thinning or clearcut head is configured a tree harvesting vehicle supported by a plurality of wheels and tires. The improved thinning or clearcut head is adapted for use in cutting down a target tree. The improved thinning or clearcut head comprises a tree harvesting vehicle and a lateral pivot apparatus. The tree harvesting vehicle comprises a harvest vehicle and a cutting tool. The lateral pivot apparatus attaches the cutting tool to the harvest vehicle such that the cutting tool rotates around a lateral axis of rotation that is parallel to the center axis of the target tree. The improved thinning or clearcut head aligns the cutting tool with the target tree such that the alignment axis between the clamping arms of the cutting tool and the target tree is offset from primary sense of direction of the harvest vehicle.

  • Patent number: 11383342
    Abstract: A method and a cylindrical grinding machine for centerless cylindrical grinding of a workpiece. The workpiece is supported on a first contact surface and a second contact surface arranged at an angle relative to one another. A grinding disk is applied to the workpiece with an application force, whereby the workpiece is in turn pressed against the first and second contact surfaces, which cause braking of the workpiece (which is rotationally driven solely by the grinding disk). The braking reduces the rotational speed of the workpiece such that the grinding disk produces grinding in addition to rotationally driving the workpiece. The rotational speed of the workpiece can be precisely set by means of an additional brake that applies an adjustable braking force to the workpiece.

  • Patent number: 7712495
    Abstract: A wooden stake sharpening machine moves a conical cutting head along a linear path into engagement with a clamped wooden stake blank to affect sharpening thereof. A walking beam conveying apparatus moves a wooden stake blank into position from a supply bin where a clamping apparatus holds the stake blank in place while the cutting head moves onto the stake to form a point thereon. The drive mechanism moves the conveyor in coordination with the linear movement of the cutting apparatus, which trips a switch to actuate the clamping mechanism as the cutting head moves toward engagement with the stake blank. The conveyor then moves the sharpened stake toward a collection area while moving another stake blank into position for sharpening as the cutting apparatus is retracted away from the stake, thus providing an automated stake sharpening machine with a minimal number of moving parts.

  • Patent number: 5638877
    Abstract: Apparatus for fashioning a pointed end on a stake includes a base on which is mounted a rotatably driven slotted circular disk having secured to one side thereof a plurality of cutting blades co-disposed in a radially outward arrangement within a cutting plane of the disk. A feed table is displaceably mounted on the base adjacent the cutting plane of the disk and supports a hollow cylinder having open ends for receiving a wooden stake and retaining a free end thereof in a predetermined angular cutting engagement with the cutting plane. Forward travel of the stake through the cylinder is limited by a stop member and lateral displacement of the stake relative to the cutting plane is provided by a handle operated cam that controllably moves the feed table to establish a predetermined depth of cut. The stake is rotated within the cylinder either manually or by a motor driven rotator which results in pinpointing the extended end of the stake.

  • Patent number: 5562956
    Abstract: Processes are provided for producing wood chips with a variety of cross sections such as those resembling botanical leaves and other decorative designs. The processes also produces wood chips that have coloration and shading. A rough form of wood having a elongated length is extruded lengthwise to make an extrusion having a decorative cross section. The extrusion is then cut at an angle to the direction of the elongated length of the extrusion into a plurality of wood chips having the desired cross-section. The step of cutting the extrusion involves positioning a lengthwise end of the extrusion adjacent at least one cutting blade oriented at an angle in the range of about 15 degrees to about 75 degrees relative to the elongated length of the extrusion, providing a relative rotational movement between the extrusion and the blade about the longitudinal center of gravity of the extrusion, and providing a relative linear movement between the extrusion and the blade in the elongated direction towards one another.

  • Patent number: 4387751
    Abstract: An elongated upright open framework defines a vertical workpiece passageway intermediate the frame sides and ends open toward one end of the frame bottom portion for horizontally receiving workpieces from a laterally disposed feed conveyor. The frame supports a carriage for reciprocation between its ends which is driven by a drive motor and a drive train. Pairs of clamp jaws, disposed at respective end portions of the carriage, are opened and closed by carriage movement to grip and release the respective workpiece end portions as it travels with the carriage. One pair of clamp jaws is moved by cam rollers following a cam groove on inner surfaces of the frame to contact one end portion of the workpiece with rotary cutters disposed above and below the travel path of the carriage as the carriage moves to a workpiece release position. A drive motor operated conveyor discharges the finished workpiece from the frame.
