Abstract
Abstract A compactor tool for use in conjunction with a mobile prime mover having a vibratory frame to which said tool is mounted. A tool shank is adapted for selective mounting to the vibratory frame and carries a compactor shoe pivotally mounted to the shank lower end, said shoe compacting filled or partially filled conduit burial trenches. Shoes of different widths are readily attachable to said shank for the compacting task at hand. Fluid dispersal means delivers fluid in a metered manner to the shoe when used for compacting paved surfaces.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A tool for compacting earthen material within and covering a conduit burial trench by successive passes in opposite directions, said tool for attachment to a mobile prime mover having vibratory means thereon, said tool comprising, a shank in perpendicular relationship to the surface being compacted and adapted at its upper end for pinned attachment to shank mounting means on the prime mover, a shoe having upturned leading and trailing surfaces and an imperforate bottom surface, reinforcing bars extending lengthwise of the shoe, pivot means coupling said shoe to the lower end of said shank permitting inclination of the shoe about the axis of said pivot means during a compacting operation so as to permit the forwardly or rearwardly moving shoe to ride over material being compacted, and said shoe contactable with said shank at points spaced from said axis to limit shoe inclination about said axis during tool operation.
Claim 2
Dependent Claim
149 words
A tool for compacting earthen material within and covering a conduit burial trench by successive passes in opposite directions, said tool for attachment to a mobile prime mover having vibratory means thereon, said tool comprising, a shank in perpendicular relationship to the surface being compacted and adapted at its upper end for pinned attachment to shank mounting means on the prime mover, a shoe having upturned leading and trailing surfaces and an imperforate bottom surface, reinforcing bars extending lengthwise of the shoe, pivot means coupling said shoe to the lower end of said shank permitting inclination of the shoe about the axis of said pivot means during a compacting operation so as to permit the forwardly or rearwardly moving shoe to ride over material being compacted, and said shoe contactable with said shank at points spaced from said axis to limit shoe inclination about said axis during tool operation.
Claim 3
Dependent Claim
62 words
The tool as claimed in claim 1 wherein said reinforcing bars are in spaced parallel relationship, said shank terminating at its lower end between said bars, said pivot means embodied within a quick release pin extending through said bars and the shank end, said quick release pin permitting shoe substitution for compacting subterranean surfaces of greater width than a conduit burial trench.
Claim 4
Dependent Claim
60 words
The tool as claimed in claim 1 additionally including fluid dispersal means affixed to the forward portion of the shoe, said dispersal means including a reservoir, means detachably mounting said reservoir on the shoe reinforcing bars, a conduit disposed transversely along an edge of said shoe in communication with said reservoir for metering fluid to the underside of the shoe.
Claim 5
Dependent Claim
35 words
The tool as claimed in claim 1 additionally including means interconnecting one extremity of the shoe to a point on said shank to bias the forward end of the shoe toward an upwardly inclined position.
