Abstract
Abstract Guide wheels with eccentric adapter bushings to provide precision attachment relatively to tracks. Each guide wheel is formed in a double V which provides four inclined circular surfaces permitting use both in horizontal and vertical position and adapted to co-operate with tracks of suitable angles both by the enclosed central groove and by the two outside inclined annular surfaces. The eccentric nut and bolt permits the accurate shifting of the wheel for precision adjustment. The mounting surfaces of the track are accurate and held to close tolerances and are interchangeable.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
107 words
A guide wheel for a rail comprising a guide wheel body, a pair of inclined peripheral inside walls converging inwardly and toward the middle of the width of said wheel body to form an annular guide channel of substantially V-shaped crosssection, a peripheral outside wall adjacent each inside wall forming cross-sectionally a substantially V-shaped radially outward apex with the adjacent inside wall, the inclosed angle between the pair of inside walls, and between each inside wall and the adjacent outside wall being substantially ninety degrees, thereby to selectively ride on a guide rail between the said pair of inside walls or straddling said pair of outside walls.
Claim 2
Dependent Claim
107 words
A guide wheel for a rail comprising a guide wheel body, a pair of inclined peripheral inside walls converging inwardly and toward the middle of the width of said wheel body to form an annular guide channel of substantially V-shaped crosssection, a peripheral outside wall adjacent each inside wall forming cross-sectionally a substantially V-shaped radially outward apex with the adjacent inside wall, the inclosed angle between the pair of inside walls, and between each inside wall and the adjacent outside wall being substantially ninety degrees, thereby to selectively ride on a guide rail between the said pair of inside walls or straddling said pair of outside walls.
Claim 3
Dependent Claim
27 words
The guide wheel for a rail defined in claim 1, and said guide rail being formed with inclined sides converging to an apex substantially at right angles.
Claim 4
Dependent Claim
34 words
The guide wheel and track defined in claim 2, and the rail formed by said inclined sides of said track straddling said wheel and fitting over the inclined outside walls of said guide wheel.
Claim 5
Dependent Claim
52 words
The guide wheel defined in claim 1, and antifriction bearing means in said wheel, a bearing support in said bearing means having an eccentric hole therethrough, a mounting element axially through said eccentric role of said bearing support for mounting said bearing support in selected eccentric position relatively to said mounting means.
Claim 6
Dependent Claim
74 words
The guide wheel defined in claim 1, and parallel pairs of said rails facing one another, a guide wheel in engagement with each rail, a support for the guide wheels between said pairs of rails, mounting means for mounting each wheel on said support, and journal means for each wheel adjustable eccentrically relatively to said mounting means for adjusting the position of said wheels relatively to the respective rails and relatively to one another.
Claim 7
Dependent Claim
28 words
The guide wheel defined in claim 1, and said rail being formed with three intersecting inclined sides converging to two parallel apices at right angles to one another.
