Stacker alignment device
First Claim
1. Apparatus for determining the alignment of a wheel or a rail-supported vehicle with respect to the rail comprising a base member, means for maintaining a surface of said base member in contact with a surface of said wheel perpendicular to its axis of rotation, an elongated first bar mounted at one end to said base member for pivotal movement about an axis parallel to said surface of said base member, means for selectively fixing said first bar relative to said base member in a position perpendicular to said surface of said base member, means fixed to the opposite end of said first bar operable to indicate the angular orientation of said first bar relative to horizontal when said surface of said base member is in contact with said wheel and said first bar is in said fixed position, and first and second guide rods extending outward from said base member in position to straddle said wheel, at least one of said guide rods curving upward and outward such that contact of the rod with the rail causes the apparatus to move upward in relation to the rail when the apparatus is moved toward the rail.

Abstract
A device for facilitating the field alignment of the drive and idler wheels of a rail supported S/R machine. Vertical alignment is determined by means of a spirit level at the end of a pivotally mounted bar which is initially set perpendicular to a surface of a base member in magnetic engagement with the side of the wheel, the degree of misalignment being indicated by a dial indicator in contact with the bar. Longitudinal misalignment is determined by a parallelogram assembly one side of which is parallel to the surface of the base member and which includes a pair of spaced apart pins, one stationary and one movable, which engage the rail under the influence of a biasing force applied to the parallelogram assembly. The extent and direction of movement of the movable pin indicates the extent and direction of longitudinal misalignment of the wheel as read by a dial indicator in contact with the movable pin. The invention also provdes a lead-in device for placing the alignment device in engagement with the wheel to be aligned.
