| 20100115803 | Ground engaging digging tooth - A one-piece digging tooth having a socket opening to a rear end of the tooth for receiving and accommodating at least a lengthwise portion of a nose portion of an adapter extending forward from earth working equipment. The digging tooth has a top surface and a bottom surface which angularly diverge from each other between a forward end and the rear end of the tooth and two side surfaces. The tooth further includes a longitudinally elongated and centrally disposed tine with another longitudinally elongated tine outwardly cantilevered from and disposed to opposite lateral sides of and extending generally parallel to the central tine. To enhance their penetration capability, a width and thickness of all the tines constantly diminishes as the tines longitudinally extend toward the forward edge of the tooth. Opposed side surfaces on each tine are separated from each other by a longitudinally cleft whereby providing the digging tooth with at least two channels for directing materials, worked free by the tines, rearwardly toward and into the earth working equipment. | 05-13-2010 |
| 20110030248 | Tooth assembly and related method for releasably coupling a tooth to an adapter - A tooth assembly including an adapter and a tooth. The adapter has a nose portion with a first predetermined configuration. The tooth is assembled onto the adapter nose portion by relative longitudinal movement. The tooth defines a blind cavity having a second predetermined configuration and opening to a rear of the tooth. The second predetermined configuration defined by the tooth cavity is greater than the first predetermined configuration defined by the adapter nose portion such that a space is provided between the adapter nose portion and the blind cavity when the adapter and tooth are arranged in operable combination relative to each other. A securement member releasably maintains the tooth and the adapter nose portion in operable combination relative to each other. The securement member fills the space defined between the tooth cavity and the adapter nose portion to resist longitudinal movement between the tooth and the adapter nose portion. A related method for releasably coupling a tooth to an adapter is also disclosed. | 02-10-2011 |
| 20110191999 | Pin tool assembly for acting on a retaining pin for a tooth of a ground engaging implement - A pin tool assembly for forcibly removing a first type of retaining pin from digging teeth arranged in side-by-side relation across a forward edge of a digging implement. The pin tool assembly includes a tool defining a blind recess laterally disposed to one side of the tool. The tool assembly further includes an elongated extractor pin having an enlarged head portion and a shank portion extending from the head portion. Cooperating instrumentalities maintain and position the extractor pin relative the tool such that, when a force is applied to the tool, the free end of the shank portion of the pin engages with and forcibly extracts the retaining pin from the digging tooth. Preferably, the tool further defines a plurality of openings for snugly accommodating a series of retaining pins therein | 08-11-2011 |
