Abstract
Abstract Apparatus for supporting and rotating cylindrical members while being treated. The member is mounted upright on a rail which slopes downwardly toward the work station. On the downhill side of the work station, there is a stop to hold the wheel at the station until it is fully treated. The rail is vibrated on a line of movement between a vertical line and the uphill slope of the rail so that the member is raised slightly off the rail and away from the stop and then falls back onto the rail and rolls downhill against the stop. Another embodiment uses a mechanism of the slow-work-stroke-and-quick-return type, so that on the uphill stroke of the rail, the member rotates on the rail, whereas on the return stroke, the rail moves fast enough to slide under the member. In another embodiment, the rail is moved longitudinally a distance sufficient to rotate the wheel in its position against the stop through the required arc.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
88 words
Mechanism to rotate a workpiece having a circular periphery, comprising a sloping surface in contact with the workpiece at a point on the bottom portion of said periphery, a stop adapted to prevent downhill roll of the workpiece on said surface in contact with the downhill side of said workpiece at a second point located on a peripheral arc extending from the middle to the bottom of the workpiece, and means to reciprocate the sloping surface in a direction having at least a component parallel to said surface.
Claim 2
Dependent Claim
88 words
Mechanism to rotate a workpiece having a circular periphery, comprising a sloping surface in contact with the workpiece at a point on the bottom portion of said periphery, a stop adapted to prevent downhill roll of the workpiece on said surface in contact with the downhill side of said workpiece at a second point located on a peripheral arc extending from the middle to the bottom of the workpiece, and means to reciprocate the sloping surface in a direction having at least a component parallel to said surface.
Claim 3
Dependent Claim
21 words
Mechanism as in claim 1, wherein said surface has a slope of from 3*-20*, and means to render ineffective said means.
Claim 4
Dependent Claim
71 words
Mechanism as in claim 1, wherein said surface is supported for movement on a line of movement extending between the vertical and the uphill slope of said surface and means to apply a vibratory force to the surface sufficient to move said workpiece away from said stop in one direction of movement and to move said surface downwardly away from said bottom point of contact in the other direction of movement.
Claim 5
Dependent Claim
48 words
Mechanism as in claim 1, wherein the reciprocating means moves the support in one direction at a speed slow enough to roll the workpiece on the surface and moves the surface in the opposite direction at a speed fast enough to slide the surface relative to the workpiece.
Claim 6
Dependent Claim
28 words
Mechanism as in claim 1, wherein the surface reciprocating means includes means to move the surface a distance at least equal to the circumference of the workpiece periphery.
Claim 7
Dependent Claim
114 words
In a device to support and rotate a workpiece having a circular periphery at a work station, the improvement comprising an elongated workpiece supporting surface sloping downwardly from a loading station to the work station and in contact with the workpiece at a point on the bottom portion of said periphery, stop means to hold the piece at said work station in contact with the downhill side of said workpiece at a second point located on a peripheral arc extending from the middle to the bottom of the workpiece, and means to move the surface relative to the workpiece on a line of movement and at velocities and amplitudes sufficient to rotate the workpiece.
Claim 8
Dependent Claim
114 words
In a device to support and rotate a workpiece having a circular periphery at a work station, the improvement comprising an elongated workpiece supporting surface sloping downwardly from a loading station to the work station and in contact with the workpiece at a point on the bottom portion of said periphery, stop means to hold the piece at said work station in contact with the downhill side of said workpiece at a second point located on a peripheral arc extending from the middle to the bottom of the workpiece, and means to move the surface relative to the workpiece on a line of movement and at velocities and amplitudes sufficient to rotate the workpiece.
Claim 9
Dependent Claim
21 words
A device as in claim 6, wherein said stop means includes a removable stop member preventing downhill roll of the workpiece.
Claim 10
Dependent Claim
34 words
A device as in claim 6, wherein the workpiece support surface is on a linear element mounted for vibration on a line of movement between the vertical and the uphill slope of said surface.
Claim 11
Dependent Claim
21 words
Mechanism as in claim 1, wherein the workpiece support means is a linear element mounted for reciprocation parallel to said surface.
Claim 12
Dependent Claim
102 words
Mechanism as in claim 1, wherein said reciprocating means includes at least one leaf spring secured to said workpiece support means at such an angle that as said spring is flexed said support moves on a line of movement between the vertical and its uphill slope and means to apply a vibratory force to the piece support means of an amplitude and frequency as to move said workpiece upwardly and away from said stop means and said workpiece surface away from said workpiece periphery whereby said workpiece drops to said surface under the force of gravity and rolls to said stop means.
Claim 13
Dependent Claim
111 words
Mechanism to rotate a cylindrical workpiece having a circular periphery through a desired arc comprising an elongated supporting member in contact with the workpiece at a point on the bottom portion of said periphery, means to support the member on a slope, stop means to hold the workpiece against downhill roll on the member in contact with the downhill side of said workpiece at a second point located on a peripheral arc extending from the middle to the bottom of the workpiece, and means to reciprocate the member in one direction in rolling contact with the workpiece and in the opposite direction without reversing the direction of rotation of the workpiece.
