An apparatus, system and method for hydraulically adjusting and setting a fixed position of an axially displaceable shaft (220) and rotary chipper disc (210) combination, without requiring an attachment to or obstruction of an end face (222) of either end of the axially displaceable shaft (220). A rotary chipper disc recoil mechanism is also provided for the purpose of detection of unwanted axial and radial forces placed upon the rotating shaft caused by unintentional chipping of metal, and for limiting consequential damage caused by the unintentional chipping of metal and other non- wood materials.

A heavy duty rotary disc-type wood chipper containing a knife clamping system that conducts the impact and shearing loads acting upon the chipper knives along two primary axes which allows for more efficient dissipation of the impact loads and a reduction in the deleterious effects of off-axis loads resulting in the ability to use smaller holding bolts and smaller knives in the system without adversely effecting either the ability of the knives to stay fixed to the disc or the quality of chips produced.

Primary and counter knife assembly for use in wood chipper
A wood chipper having a rotatable disc that contains a series of slots that pass through the disc. A primary chipper knife is located at the entrance of each slot which separates slices from a work piece and directs the slices through the slot. A counter knife unit is mounted within each slot for engaging the slices leaving the primary chipper knife to reduce the size of the chips as they move through the slot. The counter knife unit contains a first series of spaced apart chip contact elements that have a first height to contact the slices as they leave the primary chipper knife to reduce the size of the slices. The counter knife further contains a second series of chip contact elements that have a second height that is less than that of the chip contact element in the first series. Each contact element in the second series is arranged to contact chips leaving the contact elements in the first series to further reducing the size of the chips.
A disc type wood chipper that utilizes a high percentage of the energy required for chipping but not substantially utilized in the material size reduction within the machine to produce chips of a small enough size such that the chips produced can be turned into wood flour or wood pellets with the expenditure of very little additional energy.
An adjustment mechanism for a rotary disc chipper apparatus includes an axially displaceable shaft attached to a chipper disc, at least one gear disposed in relation to the axially adjustable shaft and a drive member engageable with the at least one gear to produce axial movement of the axially displaceable shaft and the chipper disc.

A disc cutting apparatus for chipping wood chips from a log includes a chipper frame, a rotary cutting disc having a plurality of substantially radially- disposed knife assemblies in relation to a proximal facing side of the disc and a feed spout into which a log is fed into the chipper apparatus. The apparatus further includes a bedknife, the bedknife having a first surface and an opposing second surface that is nonparallel to the first surface such that a wedge is produced between the first surface and the second surface for fitting within a corresponding nonparallel gap in the chipper frame. The bedknife further includes at least one secondary trimming edge for more complete reduction of wood chipped and for reducing the size of slivers formed.
