Abstract
Abstract A glass container undergoing inspection is stabilized with two tapered rolls which engage a rim portion thereof. The container is rotated by a drive wheel which engages one edge of the container heel. One tapered roll holds the container in contact with the drive wheel. The other, diametrically opposed tapered roll holds the opposite side of the container heel at a generally fixed elevation above a slide plate by providing a balancing reaction force to the forces exerted by the first tapered roll and the drive wheel. Both tapered rolls are spring loaded and pivotally mounted to allow forcing a glass container into engagement with them as the container enters the inspection position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
153 words
In an apparatus for inspecting glass containers wherein the containers are moved in series to and through an inspection station where a portion of the container heel is exposed to viewing by inspection apparatus positioned below through an opening in a container bottom supporting plate and wherein the containers are rotated about their vertical axis by engagement of the container heel with a rotating drive wheel located at the inspection station, the improvement in holding the container in engagement with the drive wheel and maintaining the container axis substantially vertical during such engagement which comprises: a first rotatably mounted tapered roller positioned in contact with an inner edge of a rim portion of said glass container at a location generally above said drive wheel; and a second rotatably mounted tapered roller positioned in contact with the inner edge of said rim portion at a location substantially diametrically opposed to said first tapered roller.
Claim 2
Dependent Claim
153 words
In an apparatus for inspecting glass containers wherein the containers are moved in series to and through an inspection station where a portion of the container heel is exposed to viewing by inspection apparatus positioned below through an opening in a container bottom supporting plate and wherein the containers are rotated about their vertical axis by engagement of the container heel with a rotating drive wheel located at the inspection station, the improvement in holding the container in engagement with the drive wheel and maintaining the container axis substantially vertical during such engagement which comprises: a first rotatably mounted tapered roller positioned in contact with an inner edge of a rim portion of said glass container at a location generally above said drive wheel; and a second rotatably mounted tapered roller positioned in contact with the inner edge of said rim portion at a location substantially diametrically opposed to said first tapered roller.
Claim 3
Dependent Claim
20 words
The improvement of claim 1 further including means for biasing said first and second tapered rollers in a downward direction.
Claim 4
Dependent Claim
27 words
The improvement of claim 2 further including stop means for limiting the downward movement of said first and second tapered rollers to a pre-selected maximum downward location.
Claim 5
Dependent Claim
38 words
The improvement of claim 1 wherein each of said first and second tapered rollers is of a generally frusto-conical shape and wherein the angle of taper of said first and second tapered rollers is between 5* and 30*.
Claim 6
Dependent Claim
30 words
The improvement of claim 1 wherein said first and second tapered rollers each further include a reverse tapered portion connected thereto, said reverse tapered portions tapering inwardly toward one another.
Claim 7
Dependent Claim
101 words
Apparatus for controlling the rotation about its vertical axis of a glass container, having an open mouth defining a rim, at an inspection station by engagement of the heel portion of the container with a rotating drive wheel, comprising, in combination: a first tapered roller positioned in contact with the inner edge of said rim vertically adjacent the location of said drive wheel; a second tapered roller positioned in contact with the inner edge of said rim at a location substantially diametrically opposed to that of said first tapered roller; and means for rotatably supporting said first and second tapered rollers.
Claim 8
Dependent Claim
101 words
Apparatus for controlling the rotation about its vertical axis of a glass container, having an open mouth defining a rim, at an inspection station by engagement of the heel portion of the container with a rotating drive wheel, comprising, in combination: a first tapered roller positioned in contact with the inner edge of said rim vertically adjacent the location of said drive wheel; a second tapered roller positioned in contact with the inner edge of said rim at a location substantially diametrically opposed to that of said first tapered roller; and means for rotatably supporting said first and second tapered rollers.
Claim 9
Dependent Claim
20 words
The apparatus of claim 6 further including means for biasing said first and second tapered rollers in a downward direction.
Claim 10
Dependent Claim
28 words
The apparatus of claim 7 further including stop means for limiting the downward movement of both said first and second tapered rollers to a pre-selected maximum downward location.
Claim 11
Dependent Claim
38 words
The apparatus of claim 6 wherein each of said first and second tapered rollers is of a generally frusto-conical shape and wherein the angle of taper of said first and second tapered rollers is between 5* and 30*.
Claim 12
Dependent Claim
151 words
The apparatus of claim 6 wherein said means for rotatably supporting said first and second tapered rollers comprises: a horizontal rod extending across the open mouth of said container at an elevation above said open mouth; a first clamp bar, attached to said horizontal bar and extending downwardly therefrom, on one side of said open mouth; a second clamp bar, attached to said horizontal bar and extending downwardly therefrom, located substantially diametrically opposed to said first clamp bar; a first rock arm, pivotally mounted on said first clamp bar, extending toward said open mouth; a second rock arm, pivotally mounted on said second clamp bar, extending toward said open mouth; a first shaft, mounted on said first rock arm, carrying a bearing upon which said first tapered roller is mounted; and a second shaft, mounted on said second rock arm, carrying a bearing upon which said second tapered roller is mounted.
Claim 13
Dependent Claim
34 words
The apparatus of claim 6 wherein said first and second tapered rollers each further include a reverse tapered portion connected thereto, said reverse tapered portions tapering inwardly toward the center of said open mouth.
