## Abstract

An adjustable tamping wheel forms a berm of a desired cross section over a recently filled trench. The tamping wheel contains a center spindle, an offset left spindle, an offset right spindle, a freely rotating center basket on the center spindle with transverse tamping members, a freely rotating left basket on the left spindle with inwardly converging transverse tamping members, and a freely rotating right basket on the right spindle with inwardly converging transverse tamping members.

## Claims

### Claim 1

An adjustable tamping wheel for forming a berm of a desired cross section over a filled trench, the tamping wheel comprising:
(a) a center spindle defining a first horizontal axis;
(b) an offset left spindle attached to the center spindle and defining a second horizontal axis that is different from the first horizontal axis;
(c) an offset right spindle attached to the center spindle and being in the second horizontal axis defined by the left spindle;
(d) a freely rotating center basket on the center spindle, the center basket comprising: (i) a disc defining a plane perpendicular to the horizontal axis defined by the center spindle, the disc having an outer edge and a circumference; and (ii) a plurality of horizontal transverse tamping members attached along the outer edge;
(e) a freely rotating left conical basket on the left spindle, the left basket comprising: (i) an inner ring having an outer edge with a circumference less than the circumference of the disc of the center basket; (ii) an outer ring having an outer edge with a circumference greater than the circumference of the disc of the center basket; and (iii) a plurality of inwardly converging transverse tamping members extending from the outer ring to the inner ring;
(f) a freely rotating right conical basket on the right spindle, the right basket comprising: (i) an inner ring having an outer edge with a circumference less than the circumference of the disc of the center basket; (ii) an outer ring having an outer edge with a circumference greater than the circumference of the disc of the center basket; and (iii) a plurality of inwardly converging transverse tamping members extending from the outer ring to the inner ring; and
(g) a means for adjustably fixing the distance between the left conical basket and the right conical basket.

### Claim 2

An adjustable tamping wheel for forming a berm of a desired cross section over a filled trench, the tamping wheel comprising:
(a) a center spindle defining a first horizontal axis;
(b) an offset left spindle attached to the center spindle and defining a second horizontal axis that is different from the first horizontal axis;
(c) an offset right spindle attached to the center spindle and being in the second horizontal axis defined by the left spindle;
(d) a freely rotating center basket on the center spindle, the center basket comprising a plurality of horizontal transverse tamping members;
(e) a freely rotating left conical basket on the left spindle, the left basket comprising a plurality of inwardly converging transverse tamping members;
(f) a freely rotating right conical basket on the right spindle, the right basket comprising a plurality of inwardly converging transverse tamping members; and
(g) a means for adjustably fixing the distance between the left conical basket and the right conical basket.
