| 20080237377 | Feed roller drive for wood chipper - The present disclosure relates to a wood chipper that has a feed roller driven by a hydraulic motor. Hydraulic fluid under pressure is provided to the motor through a two-stage pump, providing separate flows of fluid under pressure. The flows of the pump stages are combined for normal operation of the chipper. A bypass that will bypass the flow from one pump stage when the pressure of the fluid under pressure driving the motor exceeds a pre-selected level from increased load on the feed roller is provided. When the bypass is open the feed roller is slowed to reduce the feed rate of material into the chipper, and when the feed roller loads reduce, the flows will again be combined to speed up the feed roller. | 10-02-2008 |
| 20080272215 | Brush Chipper with Improved Feed Rollers - An improved feed roller assembly wherein the feed roller provides a force perpendicular to the feed direction of the brush material.

| 20090108110 | DEVICE AND METHOD FOR IMPROVING GRINDING EFFICACY IN GRAVITY-FED GRINDING MACHINES - The present invention regulates the delivery of feedstock to the fragmentation zone in a gravity-fed comminuting machine and reduces the ejection of feed materials by means of a rotating cylinder located at an offset position above the rotor.

| 20100163656 | Method of Controlling a Brush Chipper - An improved brush cutter having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member with selectable sensitivity. Another aspect of the invention is to predict the feed roller shutoff point according to the rate of engine deceleration. According to another aspect, when the feed rollers stop feeding material into the cutters, to overcome drag on the cutters, a controller stops the feed rollers and then reverses them for a short time, and then reverses the rollers again if the problem is still present. To prevent jamming, a pressure switch senses when oil in a hydraulic motor system for rotating the feed rollers is too high and the controller momentarily reverses the feed rollers and then causes them to go forward, a cycle which can occur several times until the feed rollers are no longer stalled. By another aspect of the invention, the controller senses characteristics of the brush cutter and chooses an operating system based on the characteristics sensed. The controller can also sense if the brush chipper has not been used for a predetermined period of time and automatically reduce the idle speed of the engine until the brush chipper is used again, and then automatically return the engine to a normal idle speed before the feed rollers will pull brush into the brush chipper. | 07-01-2010 |
