Appl. No.:

9/757188

Inventors:

Mark A. Morgan - Tulsa OK

Assignee:

TDW Delaware, Inc. - Wilmington DE

International Classification:

F16L 5516

US Classification:

138 89

Abstract:

A closure for an opening extending through a tubular member, the opening having a first cylindrical surface of a first internal diameter and a second cylindrical surface of an enlarged internal diameter providing a circumferential ledge, and, in the second cylindrical surface an increased internal diameter circumferential slot, the closure being formed of a cylindrical plug removably positioned within the tubular member and in engagement with the circumferential ledge and including an expandable snap ring having a collapsed and an expanded condition and receivable when in the expanded condition within the circumferential slot to capture the plug between the circumferential ledge and the snap ring. In one embodiment the snap ring is a unitary circumferential member having opposed, spaced apart first and second ends and wherein the snap ring is radially inwardly collapsed by moving the first and second ends towards each other. In another embodiment the snap ring is formed of first and a second leaf portions, each portion having a first end and a second end, each leaf portion being hinged to the plug body adjacent the first end thereof, the leaf portions being radially positioned by moving the second ends thereof towards or away from each other.

International Classification:

E02F 502

US Classification:

37 80A

Abstract:

A side cutter apparatus for an excavating machine having a plurality of spaced rotating digging wheels mounted on a common horizontal shaft, each wheel having a pair of spaced sidewalls, and having frame rails partially extending into the spaces between adjacent wheels; which includes a base plate affixed to the periphery of a cut-away section of a sidewall adjacent to the open space between the wheels; a pivotal side cutter including a back panel disposed in the cut-away section and pivotally mounted at its lower end on the base plate so as to pivot into the open space, a front panel disposed essentially parallel to the back panel and pivotally mounted at its lower end on a common axis with the back panel so as to be pivotally movable therewith, a cutting tooth affixed to the upper portion of the front panel and extending into the open space, a roller rotatably mounted on an axis perpendicular to the front panel and extending through the same into a vertical space between the panels wherein the roller is directly adjacent to the open space between the wheels; a spring for urging the side cutter into the open space; a stop for limiting the pivotal movement of the side cutter, a cam for moving the side cutter into a closed position against the action of the spring, and a track for maintaining the side cutter in the closed position during a predetermined portion of the wheel's rotation.
