Abstract
Abstract A soil compactor more specifically a soil compacting device to expedite compaction of soil backfill in ditch work. The device consists of a wheel having a concave rim, adapted to be drawn by a towing vehicle in operative positionment in a ditch being backfilled. The compaction wheel is designed to have a vibratory action and includes mechanism for adjusting vibration frequencies and amplitudes to attain maximum density. For adjusting the vibrating action an adjustable eccentric is operatively associated with a revolving center shaft of the wheel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
143 words
A soil compactor comprising: A. a frame adapted to be drawn by a tow vehicle; B. a compactor wheel; C. an axle rotatably mounting said compactor wheel on said frame; D. a compactor wheel vibrator unit operatively associated with said axle including: i. a cylindrical shaped main body coaxial with said axle; ii. a separable segment of said main body constituting an eccentric member adjustably mounted in said main body and radially adjustably movable away from or toward said main body and the axis of rotation thereof; and iii. means for selectively adjustably moving said segment away from or toward said main body to a selected eccentric position with respect to the axis of rotation thereof, and E. drive means for said axle operable upon selected eccentric adjustment of said segment to impart selected vibration forces to said compactor wheel through said axle.
Claim 2
Dependent Claim
143 words
A soil compactor comprising: A. a frame adapted to be drawn by a tow vehicle; B. a compactor wheel; C. an axle rotatably mounting said compactor wheel on said frame; D. a compactor wheel vibrator unit operatively associated with said axle including: i. a cylindrical shaped main body coaxial with said axle; ii. a separable segment of said main body constituting an eccentric member adjustably mounted in said main body and radially adjustably movable away from or toward said main body and the axis of rotation thereof; and iii. means for selectively adjustably moving said segment away from or toward said main body to a selected eccentric position with respect to the axis of rotation thereof, and E. drive means for said axle operable upon selected eccentric adjustment of said segment to impart selected vibration forces to said compactor wheel through said axle.
Claim 3
Dependent Claim
27 words
A soil compactor as claimed in claim 1, wherein the eccentric adjusting means is actuatable exteriorally of said wheel and said frame without disassembling the compactor mechanism.
Claim 4
Dependent Claim
26 words
A soil compactor as claimed in claim 2, wherein said compactor wheel includes a concave rim adapted for compacting soil and earth in backfilling of trenches.
Claim 5
Dependent Claim
39 words
A soil compactor as claimed in claim 3, said adjustable segment being of substantial mass and geometrically sized and configured to interleave with and conform in shape to the periphery of said main body when in a retracted position.
Claim 6
Dependent Claim
123 words
A soil compactor as claimed in claim 1, wherein said adjusting means includes a bore in said axle, a toothed pinion shaft extending into said bore from the exterior end of said axle and rotatable therein, said main body having inwardly extending openings therein, rack means secured to said adjustable segment movably mounted in said openings and in operative engagement with said toothed pinion shaft, and mating guide pins and holes interengaging said adjustable segment and said main body, whereby upon rotation of said pinion shaft from the exterior end of said axle said pinion and rack means operate to extend or retract the adjustable segment into the selected eccentric relationship with respect to said main body for vibratory adjustment of said wheel.
Claim 7
Dependent Claim
22 words
A soil compactor as claimed in claim 5, and further including removable locking bolts intergaging said main body and said pinion shaft.
Claim 8
Dependent Claim
32 words
A soil compactor as claimed in claim 6, said axle drive means comprising a hydraulic motor adapted for operative connection with fluid pressure from a pump of a tow vehicle hydraulic system
