  • Patent number: 10029389
    Abstract: A baseball bat fabricated from a limb of a tree, procured without harvesting any of the tree's trunk. Because of this technique, the process of the present invention is much less wasteful. Many bats can be fabricated from a single tree, without felling the tree itself. The process of fabrication of the present invention is drawn to working with the properties of the harvested tree limb. In this manner, a billet is fabricated on a lathe with its center placed concentric with the center of the tree limb, thusly concentric with the limb's growth rings. By doing so, the growth rings within the limb will not be bisected during fabrication of the billet. When the billet is further turned on a lathe to shape the billet into a baseball bat, the growth rings within the limb will be minimally bisected, thus increasing the strength of the baseball bat of the present invention, as compared to the baseball bats of the prior art.

  • Patent number: 7658215
    Abstract: A wood chipper includes a control system for controlling feed wheel rotation and engine operation to provide safety features and a fuel-saving mechanism. The control system allows the engine to start only when the feed wheel is in neutral; stops and/or reverses rotation of the feed wheel in response to an increased load on the engine; and dethrottles the engine if the feed wheel remains in neutral for a predetermined period of time. A pair of electric switches are activatable by the feed bar whereby an electronic control unit (ECU) can determine the position of the feed bar based on activation or non-activation of the switches and control the feed wheel and engine in light thereof. The ECU controls a pair of directional control valves via respective solenoids to control flow of hydraulic fluid to control rotation of a feed motor which drives the feed wheel.

  • Publication number: 20090090434
    Abstract: A stump cutter controller and operator presence system includes one or more capacitive sensors in each of the three control levers that control movement of the cutter wheel. A sensor circuit measures changes in the capacitance of the sensors. The controller automatically disengages a drive clutch and applies a brake to the cutter wheel when the controller senses that an operator has left the operating station—which is assumed when the operator has not touched any one of the three control levers of the operator station for a predetermined time. The controller logic is set to allow the clutch to remain engaged during a delay period, of predetermined duration, to permit the operator to move a hand off of one control lever to another control lever. Also, a grace period, of varying duration based on the speed of the cutter wheel, may be provided during which the clutch is reengaged if an operator returns to the controls.

  • Publication number: 20080236704
    Abstract: In a wood processing plant, planks are typically split into strips and then passed through an automated cross-cutting saw station to remove defects such as knots, cracks or flash. One defect which also occurs is the hit and miss defect caused by a planer and/or a sander. In order to improve the performance of the cross-cutting saw station, color is applied to the wood prior to being planed and sanded. The cross-cutting saw station is then modified to optically inspect the wood for the presence of color, indicating a hit and miss defect, and to remove the portions of the wood containing color.
