## Abstract

An implement for cleaning spaces between adjacent slabs of paving materials, the implement including a pilot member proportioned to fit into the spaces between the adjacent slabs of paving materials, a pair of flange members forming a V-shape having an apex, the pilot member and the pair of flange members being joined such that the pilot member extends away from the exterior of the apex of the V-shape, a handle that extends away from the interior of the apex of the V-shape, and a pivot apparatus for providing a pivoting movement between the pair of flange members and the pilot member and the handle.

## Claims

### Claim 1

An implement for cleaning spaces between adjacent slabs of paving materials, said implement comprising:
a substantially planar pilot member proportioned to fit into the spaces between the adjacent slabs of paving materials;
a pair of flange members forming a V-shape having an apex;
said pilot member and said pair of flange members being joined such that said pilot member extends away from the exterior of said apex of said V-shape;
a handle that extends away from the interior of said apex of said V-shape: and
pivot means for providing a pivoting movement between:
said pair of flange members and said pilot member; and
said handle.

### Claim 2 (depends on 1)

An implement according to claim 1, wherein each of said flange members has a sloping leading face having at least one cutting edge provided thereon.

### Claim 3 (depends on 2)

An implement according to claim 2, wherein each of said sloping leading faces of said flange members has two corner edges, each of said two corner edges having a cutting edge formed thereon.

### Claim 4 (depends on 3)

An implement according to claim 3, wherein each of said cutting edges is self-sharpening.

### Claim 5

An implement for removing debris from spaces in pavement, said implement comprising:
a tool head, said tool head comprising:
at least two flange members;
each of said flange members being of trapezoidal shape and having a top side, a bottom side, and a pair of substantially nonparallel lateral sides;
said at least two flange members being attached to one another along said bottom sides to form an elongated V-shape having an apex;
a pilot member proportioned to be inserted into the spaces, said pilot member having an upper edge;
said upper edge of said pilot member being attached to said apex of said elongated V-shape and said pilot member extending downward therefrom;
one of said substantially nonparallel sides of each of said flange members being slanted to thereby form an acute angle with said bottom sides of said flange members;
a cutting edge formed on each of said slanted sides;
each of said cutting edges being substantially self-sharpening;
a pivot member attached to said apex of said elongated V-shape and extending upward therefrom;
said pivot member being disposed substantially in the same plane as said pilot member;
said pivot member having a pivot hole therethrough;
said implement additionally comprising:
a handle, said handle comprising:
an elongated handle member;
a pivot fitting;
said pivot fitting having a bifurcated end with two outstanding tines and a space disposed therebetween;
said space being proportioned to accept and accommodate said pivot member;
each of said outstanding tines being provided with a hole therethrough;
a detachable threaded connection between said handle member and said pivot fitting;
a threaded bolt for passing through said hole in said pivot member and each of said holes in said outstanding tines;
a wing nut for threading onto said bolt; and
at least two washers.

### Claim 6 (depends on 5)

An implement according to claim 5, wherein said handle member is wood.
