Text Appearing Before Image:
the same as the plain slotted shoe B (which gave thebest results for plain shoes) the performance was better than that ofshoe B. Therefore, on the basis of equivalent available bearingsurface a shoe of the flanged type will give a higher mean coefficient offriction than a plain shoe either solid or slotted. One Versus Two Shoes Per Wheel. 534. The gain in brake shoe performance with two shoes per wheel(clasp brake conditions) as compared with one shoe per wheel (stand-ard brake conditions) is most clearly shown in the comparison of thebrake shoe machine test results. This difference is less easily deter-mined from the results of the road tests because of the presence of otherfactors not present in machine tests. 535. Curves showing the average results of tests of various typesof brake shoes under both single shoe and clasp brake conditions areshown in Figs. 165 and 166. A comparison of the values of mean co-efficient of friction for standard and for clasp brake conditions shows a 275
