1. In a closed loop system of belt and pulleys a pair of belt centering and aligning tracking rollers each comprising: a. a cylindrical body of a length slightly greater than the width of the belt trained thereabout; b. separate coils of wire having oppositely pitched convolutes mounted on opposite ends of the periphery of said cylindrical body and having matched inner ends spaced from and in proximity to each other substantially midway the ends of said cylindrical body; and c. means for anchoring the respective ends of said separate coils of wire to the periphery of said cylindrical body.

2. Tracking rollers in accordance with those of claim 1, each including an annular depression in the periphery of said cylindrical body between the matched inner ends of the separate coils of wire thereon.
3. Tracking rollers in accordance with those of claim 2, in which said means for anchoring the ends of said coils of wire to the periphery of said cylindrical body includes: a. means for securing the matched inner ends of said coils of wire radially of and parallel to the axis of said cylindrical body; and b. means for securing the opposite outer ends of said coils of wire to said cylindrical body in longitudinal alignment with said matched inner ends of said coils parallel to the axis of said cylindrical body.
4. The tracking rollers in accordance with those of claim 3, in which said separate coils of wire have their oppositely pitched convolutes pitched in a direction tending to wind toward center relative to the direction of rotation of said rollers for urging the belting engaged thereby toward said annular depression between the matched inner ends of said coils of wire.
5. The tracking rollers in accordance with those of claim 4, in which said oppositely pitched coils of wire on said cylindrical body have minimal surface contact with the belting engaged thereby while urging the outer halves of the belting width toward said annular depression between the matched inner ends of said coils of wire.
6. The tracking rollers in accordance with those of claim 5, in which the lands between the oppositely pitched convolutes of said coils of wire have minimal surface contact between the peripheral surface of said cylindrical body and said belting affording a cooling effect to the latter.
7. The tracking rollers in accordance with those of claim 6, in which said separate coils of wire include waveforms undulating inwardly and outwardly radially relative to said cylindrical body.
8. The tracking rollers in accordance with those of claim 7, in which the waveforms on adjacent convolutes of said coils of wire collectively present spirally tending waveforms over the length of each end of said cylindrical body further tending to urge said belting toward thE annular depression between matched inner ends of said coils of wire.
9. The tracking rollers in accordance with those of claim 8, including a non-corrosive-non-toxic coating covering the periphery of coils of wire on said cylindrical bodies.
10. The tracking rollers in accordance with those of claim 4, in which said rollers have their oppositely pitched separate coils of wire inversely related relative to the direction of movement of the belt such that: a. the separate coils of wire on one of said rollers have their oppositely pitched convolutes pitched in a direction tending to wind inwardly toward said center annular depression relative to the direction of rotation of said one of said rollers; and b. the separate coils of wire on the other one of said rollers have their oppositely pitched convolutes pitched in a direction tending to wind outwardly from said center annular depression toward the ends of such rollers relative to the direction of rotation of the latter to thereby afford centering action by such other one of said rollers in the event of reversal of direction of movement of the belt trained about said pair of rollers.
11. The tracking rollers in accordance with those of claim 10, in which the peripheral surface of each of the said cylindrical bodies of said rollers is of greatest diameter adjacent the annular depression therein and of gradually diminishing diameter tapering toward the opposite ends of each of said cylindrical bodies.
12. In a closed loop system of belt and pulleys having end rollers distanced at any ratio of belt width to end roller centers, the combination therewith of a pair of belt centering and aligning tracking rollers and in which each of the rollers in said system comprises: a. a cylindrical body of a length slightly greater then the width of the belt trained thereabout; b. a pair of oppositely pitched equally spaced spirally tending grooves formed in the peripheral surface of said cylindrical body from matched points in proximity to each other centered substantially midway the ends of said cylindrical body; c. each of said spirally tending grooves having gradually diminishing depth from said centered matched points toward the ends of said cylindrical body; and d. a wire element spirally seated in each of said spirally tending grooves for presenting a tapering belt contacting and centering ribbing to said belting from center of said cylindrical body toward its outer edges.
13. The tracking rollers in accordance with those of claim 12, including means for securing the respective ends of said wire elements to the peripheral surface of the respective cylindrical body in alignment with each other longitudinally of said cylindrical body.
14. The tracking rollers in accordance with those of claim 13, including an annular depression formed in the peripheral surface of their respective cylindrical bodies between the innermost matched points of said grooves therein and midway the ends of said cylindrical bodies.
15. The tracking rollers in accordance with those of claim 14, in which said wire elements seated in the oppositely pitched spiral grooves on said cylindrical body have minimal surface contact with the belting engaged thereby for urging the outer halves of the belting width toward said annular depression between the matched inner ends of said coils of wire.
16. The tracking rollers in accordance with those of claim 15, in which the lands on the peripheral surface of said cylindrical body between the oppositely pitched convolutes of said wire element have minimal surface contact the belting trained thereabout affording a cooling effect to the belting.
17. The tracking rollers in accordance with those of claim 16, in which said wire elements seated in the oppositely pitched spiral grooves have waveforms undulating inwardly and outwardly radially relative to said cylindrical body.
18. The tracking rollers in accordance with those of claim 17, in which the waveforms on adjacent convOlutes of said oppositely pitched wire elements collectively present spirally tending waveforms over the length of each end of said cylindrical body further tending to urge said belting toward the annular depression between matched inner ends of said coils of wire.
19. The tracking rollers in accordance with those of claim 18, including a non-corrosive-non-toxic coating covering the periphery of coils of wire on said cylindrical bodies.
