Backhoe safety teeth

Abstract

Backhoe digging teeth where the lower portion is made wide enough on each side to almost touch an adjoining wide tooth at mid-point between the teeth and certain other features produce a safety design for digging in areas where underground utilities are known to exist. Safety teeth have a thicker rounded blunt point with rounded outside corners to enhanse safety features. Safety teeth can be installed on the bucket shanks the same as standard digging teeth.

1 . A plurality of backhoe digging teeth consisting of a safety design, when mounted on a backhoe bucket, form an almost continual planar digging edge, interrupted only with a slight space between each tooth, comprising; 
 an inside tooth design, consisting of a belled out shape, pertaining to the front and back portions of the tooth, this shape or design, beginning one-third of the length of the tooth down from the top of the tooth extending outward on both sides of the tooth, to a pre determined point and downward on both sides to the bottom digging edge portion of the tooth, producing a tooth width which is determined by a midpoint measurement between two adjacent permanently welded-on tooth adapters (This measurement changes with different width buckets and the number of adaptors attached) whereas an inside tooth is mounted between two outside teeth;    an outside tooth designed the same as the inside tooth except, the outside tooth is expanded in width only on one side and the expanded side is directed toward the inside teeth, whereas the extreme outside bottom corner is rounded sufficient to remove a sharp square corner;    two moldboard sidewalls taper from a top embodiment to a rounded blunt point at the bottom of the tooth, whereas the rounded blunt point extends across the bottom of the tooth;    a top embodiment provides a releasable connect mounting means for mounting the safety tooth to a backhoe bucket.
