Patent number: 8443504Abstract: 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.Type: GrantFiled: February 5, 2010Date of Patent: May 21, 2013Assignee: H&L Tooth CompanyInventors: Charles Clendenning, Brian L.

Patent number: 8347530Abstract: 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.Type: GrantFiled: August 4, 2010Date of Patent: January 8, 2013Assignee: H&L Tooth CompanyInventors: Charles Clendenning, Russell N.

Patent number: 7818902Abstract: 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.Type: GrantFiled: November 12, 2008Date of Patent: October 26, 2010Assignee: H & L Tooth CompanyInventors: Brian L. Launder, Charles Clendenning, Russell N. Drake

Patent number: 7658024Abstract: A universal digging tooth attachment apparatus adapted to be secured to a forward edge of a bucket lip of an earth moving implement. The universal digging tooth attachment has a first element with an elongate section defining a first generally planar surface for abutting and engaging along the length thereof with one face of the bucket lip of the earth moving implement and a second element. The second element has an elongate section defining a second generally planar surface for abutting and engaging along the length thereof with the bucket lip of the earth moving implement directly opposite from the elongate section of the first element. One of the first and second elements has an earth engaging tooth projecting therefrom. A slip joint operably connects the first and second elements to each other to allow for adjustment of a distance between the first and second planar surfaces to accommodate attachment of the digging tooth to implements having bucket lips of differing thicknesses.Type: GrantFiled: July 6, 2006Date of Patent: February 9, 2010Assignee: H&L Tooth CompanyInventors: Brian L.

Patent number: 7114272Abstract: A digging tooth adapted to extend forward from a leading edge of a bucket or the like. The digging tooth has a forward end, with an edge extending thereacross, and a rear end. The digging tooth further includes wing structure preferably formed integral with the digging tooth and extending from a surface on the tooth so as to provide the bucket with enhanced ground penetration capability while concomitantly shielding ground engaging components disposed rearwardly of a rear end of the digging tooth against wear and, thus, potentially extending the useful wear life of such components.Type: GrantFiled: April 21, 2004Date of Patent: October 3, 2006Assignee: H&L Tooth CompanyInventors: Charles Clendenning, Brian L.
