ABSTRACT:
The subject invention involves a device for sensing the depth to which a worn railroad wheel must be machined in order to reclaim the wheel tread and flange contour. The device consists of an assembly of gaging elements mounted on a support block which is, in turn, mounted on a guide rail for radial movement into contact with the wheel tread. The gaging elements include a flange edge contactor slidably mounted on the support block, a tread contactor slidably mounted on the flange edge contactor, and a flange contacting finger pivotally mounted to the tread contactor. In operation the assembly is moved radially toward the wheel until the wheel tread is contacted. The tread contactor thereafter retracts, causing the flange contacting finger to engage the gaging point on the wheel flange. Further, downward movement of the assembly causes the flange edge contactor to move into engagement with the wheel. Appropriate encoders are connected to the gage assembly to generate pulses which indicate the position of the flange edge and the new diameter to which the wheel is to be machined.
