    Abstract: FIG. 1 is an enlarged side view of an ornamental design of a tooth for use with a microtrenching blade.
    FIG. 2 is a reduced left front bottom view thereof.
    FIG. 3 is a left back bottom view thereof.
    FIG. 4 is a left front top view thereof.
    FIG. 5 is a left back top view thereof.
    FIG. 6 is a front view thereof.
    FIG. 7 is a back view thereof.
    FIG. 8 is a top view thereof; and,
    FIG. 9 is a bottom view thereof.
    The right and left sides of the tooth are mirror images of each other. The broken lines in the drawings show a hole in the tooth which is shown for purposes of illustrating portions of the tooth for use with a microtrenching blade and form no part of the claimed design. Lines of light weight which do not connect to adjacent lines are provided to show contour and are not to be construed as discrete surface features.

    Abstract: FIG. 1 is a left side view of our microtrencher blade, the right side being a mirror image thereof.
    FIG. 2 is a top front left side view thereof.
    FIG. 3 is a back top right view thereof.
    FIG. 4 is a front top right view thereof.
    FIG. 5 is an edge view thereof.
    FIG. 6 is an expanded fragmentary edge view of the blade as shown in the call-out of FIG. 5.
    FIG. 7 is an expanded fragmentary left side view of a tooth as shown in the call-out location of FIG. 1.
    FIG. 8 is a close up right side view thereof; and,
    FIG. 9 is an expanded fragmentary view of the call-out location shown in FIG. 2.
    The broken line elements are included for the purposes of illustrating portions of the microtrencher blade and form no part of the claimed design. The line indicated by alternating dot-dash is a boundary line, the interior of which does not form any part of the claimed design. FIGS. 1, 2 and 5 represent callout locations for the expanded fragmentary views shown therein, with the borders of the call-out locations shown by lines of alternating lengths. Lines included with thin weight and which do not extend to any adjacent line are provided to show contour.

    Abstract: A replaceable tooth assembly. A number of tooth assemblies are provided round the periphery of a microtrenching blade. The assemblies include a cartridge, usually welded to the periphery of the microtrenching blade, and a tooth, which has a projection or flange shaped to fit within a cavity formed in the cartridge. The cartridge and projection each have a transverse hole formed in them, which, when aligned, form a continuous passage for placement of a removable pin which is used to join the cartridge to the tooth body. The cartridge may also have a more radially-aligned channel which intersects the cavity, which a rubber shim may be placed in. Such a shim reduces the relative vibration between the tooth and cartridge, improving life and reducing wear.
