Abstract
Abstract Apparatus for simultaneously rotating and longitudinally advancing cylindrical members through a test stand. The member is supported in a trough formed by a plurality of axially spaced idler rollers mounted on a first common shaft and a plurality of spaced belts each rotating over a pair of spaced pulleys, with one pulley of each pair being mounted on the first common shaft and the other pulley of each pair being mounted on a second common shaft parallel to the first shaft. The pulleys have a self aligning mounting on their respective shafts such that the plane of rotation of the pulleys may be at an angle other than perpendicular to the axis of their supporting shafts. One of the shafts is axially adjustable relative to the other so as to change the angle of the line of movement of all the belts relative to the axis of the shafts. One of the shafts is driven and has a driving connection with at least some of the pulleys mounted thereon. By relatively moving the two shafts and thus changing the angle of the belts relative to the axes of the shafts, a cylindrical member supported in the trough may be made to move axially forward backward, or remain stationary while being rotated at a constant speed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
135 words
Apparatus for simultaneously rotating and conveying a cylindrical member along its longitudinal axis which comprises: a. at least a first and second shaft; b. a plurality of spaced first rotatable roll means supported by one of said shafts; c. a plurality of spaced second rotatable roll means supported by both shafts and cooperating with said first roll means to form a V-shaped trough in which said member is supported; d. means to rotatably drive at least one of said roll means to impart rotation to said member about its axis of rotation; and e. means to adjust the plane of rotation of the second roll means so that it is in non-perpendicular relation to the longitudinal axis of said cylindrical member by moving one of said shafts along its longitudinal axis relative to the other.
Claim 2
Dependent Claim
135 words
Apparatus for simultaneously rotating and conveying a cylindrical member along its longitudinal axis which comprises: a. at least a first and second shaft; b. a plurality of spaced first rotatable roll means supported by one of said shafts; c. a plurality of spaced second rotatable roll means supported by both shafts and cooperating with said first roll means to form a V-shaped trough in which said member is supported; d. means to rotatably drive at least one of said roll means to impart rotation to said member about its axis of rotation; and e. means to adjust the plane of rotation of the second roll means so that it is in non-perpendicular relation to the longitudinal axis of said cylindrical member by moving one of said shafts along its longitudinal axis relative to the other.
Claim 3
Dependent Claim
74 words
Apparatus according to claim 1 wherein said second roll means comprises a pair of spaced pulleys, V-belt means extending between the pulleys, mounting means for said pulleys to allow self-aligning pivotal movement thereof, means to rotatably drive at least one of the pulleys, said pulleys being arranged so that the V-belt means lie in adjacent and substantially parallel relation to said first roll means to form a V-trough therebetween for receiving the cylindrical member.
Claim 4
Dependent Claim
34 words
Apparatus according to claim 2 wherein each of the pulleys is mounted on a spherical ball joint and pivotal about said joint in any plane which intersects the longitudinal axis of the cylindrical members.
Claim 5
Dependent Claim
28 words
Apparatus according to claim 1 where the surface contact area of said adjustable roll means is at least twice the surface contact area of said other roll means.
Claim 6
Dependent Claim
27 words
Apparatus according to claim 1 which includes hold down roll means to hold the cylindrical member into firm contact with the roll means in the trough therebetween.
Claim 7
Dependent Claim
155 words
Apparatus for simultaneously rotating and longitudinally advancing a cylindrical member which comprises: a. a first elongated common shaft parallel to the longitudinal axis of said cylindrical member, b. a plurality of rollers and pulleys rotatably mounted in spaced relation along the shaft, c. a second elongated common shaft, in parallel spaced relation to said first shaft, d. a plurality of pulleys rotatably mounted in spaced relation along said second shaft and belt means interconnecting each pulley on said first shaft with each pulley on said second shaft whereby said rollers and said belt means cooperatively define a V-shaped trough in which said cylindrical member is received, e. means to uniformly rotatably drive the pulleys on one of the shafts, and f. means to uniformly control the rate of longitudinal movement of said cylindrical members by varying the angle between the line of movement of said belt means and the longitudinal axis of said cylindrical members.
Claim 8
Dependent Claim
155 words
Apparatus for simultaneously rotating and longitudinally advancing a cylindrical member which comprises: a. a first elongated common shaft parallel to the longitudinal axis of said cylindrical member, b. a plurality of rollers and pulleys rotatably mounted in spaced relation along the shaft, c. a second elongated common shaft, in parallel spaced relation to said first shaft, d. a plurality of pulleys rotatably mounted in spaced relation along said second shaft and belt means interconnecting each pulley on said first shaft with each pulley on said second shaft whereby said rollers and said belt means cooperatively define a V-shaped trough in which said cylindrical member is received, e. means to uniformly rotatably drive the pulleys on one of the shafts, and f. means to uniformly control the rate of longitudinal movement of said cylindrical members by varying the angle between the line of movement of said belt means and the longitudinal axis of said cylindrical members.
Claim 9

33 words
Apparatus according to claim 6 wherein each of the pulleys is mounted on a self-aligning spherical ball joint and pivotal in any plane which intersects with the longitudinal axis of said cylindrical member.
Claim 10
Dependent Claim
33 words
Apparatus according to claim 13 wherein said means to control the rate of movement further comprises means to permit longitudinal movement of one of said shafts while maintaining said shafts in parallel relationship.
