Claim 7

The conveyor return way guide shoe of claim 5, wherein a support hole for securing said wear strips to said guide shoe is provided, wherein a pin is adapted to be inserted into said support hole to secure said wear strip to said guide shoe.

Claim 8

The conveyor return way guide shoe of claim 6, wherein said pin is an elongated shaft.

Claim 9

The conveyor return way guide shoe of claim 6, wherein said pin comprises two inwardly directed elongated shafts, adapted such that by spreading said inwardly directed elongated shafts apart, said pin can be inserted onto two of said support holes.

Claim 10

The conveyor return way guide shoe of claim 1, wherein one or more grooves are positioned longitudinally on each of said surfaces, said grooves being adapted to secure said wear strips to said guide shoe.

Claim 11

The conveyor return way guide shoe of claim 1, wherein a support means for supporting said guide shoe to said return way is provided.

Claim 12

A conveyor system guide shoe to be positioned at the front-most portion of the return way, comprising: a first wear surface, said first wear surface being adapted to engage a chain or belt of said conveyor system and to guide said chain or belt from the catenary sag onto the wear strips of the return way; a second wear surface substantially identical to said first wear surface; a third wear surface substantially identical to said first and second wear surfaces, said first, second and third wear surfaces being located along the perimeter of said guide shoe equidistant from the center of said guide shoe; and one or more grooves for securing said wear strips to said guide shoe.

Claim 13

A conveyor system guide shoe to be positioned at the front-most portion of the return way, comprising: a first wear surface, said first wear surface being adapted to engage a chain or belt of said conveyor system and to guide said chain or belt from the catenary sag onto the wear strips of the return way; a second wear surface substantially identical to said first wear surface; a third wear surface substantially identical to said first and second wear surfaces, said first, second and third wear surfaces being located along the perimeter of said guide shoe equidistant from the center of said guide shoe; and one or more grooves for securing said wear strips to said guide shoe.

Claim 14

A conveyor return way guide shoe being attachable to the return way of a conveyor system for guiding a conveyor belt or chain from the catenary sag to the return way wear strips, comprising: a substantially vertically oriented left side; a substantially vertically oriented right side; an upper wear surface adapted to engage said conveyor belt or chain and to guide said conveyor belt or chain from the catenary sag onto the wear strips of the return way, said upper wear surface extending continuously from said right side to said left side; and a second war surface located on the reverse side of said guide shoe, said second wear surface also being adapted to engage the conveyor belt or chain and to guide said conveyor belt or chain from the catenary sag onto the wear strips of the return way, said second wear surface also extending continuously from said left side to said right side; wherein said guide shoe is reversible such that either said upper wear surface or said second wear surface can be utilized to guide said conveyor belt or chain onto said wear strips, wherein said upper wear surface is oriented such that said conveyor belt or chain moves across thereon in a first direction, said upper wear surface having a curved front portion and a substantially planar rear portion relative to said first direction, wherein said second wear surface has a curved front portion and a substantially planar rear portion, said curved front portion of said second surface being adjacent said planar rear portion of said upper surface, and said planar rear portion of said second surface being adjacent said curved front portion of said upper surface.

Claim 15

A conveyor return way guide shoe being attachable to the return way of a conveyor system for guiding a conveyor belt or chain from the catenary sag to the return way wear strips, comprising: a substantially vertically oriented left side; a substantially vertically oriented right side; an upper wear surface adapted to engage said conveyor belt or chain and to guide said conveyor belt or chain from the catenary sag onto the wear strips of the return way, said upper wear surface extending continuously from said right side to said left side; and a second war surface located on the reverse side of said guide shoe, said second wear surface also being adapted to engage the conveyor belt or chain and to guide said conveyor belt or chain from the catenary sag onto the wear strips of the return way, said second wear surface also extending continuously from said left side to said right side; wherein said guide shoe is reversible such that either said upper wear surface or said second wear surface can be utilized to guide said conveyor belt or chain onto said wear strips, wherein said upper wear surface is oriented such that said conveyor belt or chain moves across thereon in a first direction, said upper wear surface having a curved front portion and a substantially planar rear portion relative to said first direction, wherein said second wear surface has a curved front portion and a substantially planar rear portion, said curved front portion of said second surface being adjacent said planar rear portion of said upper surface, and said planar rear portion of said second surface being adjacent said curved front portion of said upper surface.

Claim 16

The conveyor return way guide shoe of claim 10, wherein said support means is a square bore extending longitudinally through said guide shoe from one side to another side running parallel to said first and second surfaces.

Claim 17
