First Claim
Patent Images
1. An improved method for positioning and testing railroad wheels, said method comprising:
- moving a wheel to a first position with the wheel positioned upright in a vertical posture;
gripping the wheel about its rim and flange;
swinging the wheel about a spaced axis from said vertical posture to a substantially horizontal posture at a second position;
receiving said wheel in said horizontal posture upon a horizontal receiving means at said second position;
lowering said wheel and receiving means to a third position below said second position with said wheel resting upon a plurality of support means defining a horizontal plane;
rotating said support means and wheel about a vertical axis substantially central of said wheel; and
gauging at least one of the upper surface and the rim surface of said wheel for warpage and rotundity respectively while being rotated.

Abstract
Method and apparatus for gauging railroad wheels for warpage and rotundity and tape size wherein each wheel is received in an upright posture, where it is weighed, and then turned and lowered to rest horizontally on cushioned rotatable supports where it is gauged while being rotated about its axis by projecting light across its surfaces.

9. An improved apparatus for positioning and testing railroad wheels said apparatus comprising;
-
means to move a wheel to a first position with the wheel positioned upright in a vertical posture; gripping means to engage the wheel by its rim and flange; swinging means to pivot the gripping means and wheel engaged thereby about a spaced axis from said vertical posture to a substantially horizontal posture; horizontal receiving means for receiving and supporting said wheel at a second position, said receiving means being vertically movable between said second position and a third position spaced therebeneath; supporting means between said second and third positions, said supporting means comprising a plurality of blocks defining a horizontal plane; rotating means connected to rotate said supporting means about a vertical axis substantially central of said blocks and gauging means located adjacent said supporting means for detecting variations in at least one of the upper surface and rim surface of said wheel while being rotated on said support means. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 20)
