Abstract
Abstract Apparatus for measuring the outer diameter and ovality of outof-round articles has a first defined axis of movement and first displaceable means mounted for movement along that axis, a second defined axis of movement different from the first axis and second displaceable means mounted for movement along the second axis. A counterjaw is mounted on the first displaceable means for movement therewith and cooperates with a separate pivotally mounted jaw. The pivotally mounted jaw and the separate counterjaw are arranged for measuring the ovality of an out-ofround article to be measured. A jaw is mounted on a second displaceable means for movement therewith and cooperates with a fixed jaw for measuring the outer diameter of the article to be measured. A member is mounted on the first displaceable means which defines a surface inclined at 45* with respect to the second axis. Means having a sensing tip is mounted on the first displaceable means and arranged perpendicularly with respect to and in contact with the inclined surface for measuring the ovality of the article to be measured.

Claim 1
Independent Claim
310 words
Apparatus for measuring the outer diameter and ovality of split ring out-of-round articles, comprising in combination: a. a frame member; b. a first displaceable member mounted on said frame member for movement along a first axis of movement; c. a second displaceable member mounted on said frame member for movement on a second axis different from said first axis; d. a first abutment mounted along said first axis on said first displaceable member for movement therewith and a second abutment which is separate from said first displaceable member and is pivotally mounted on said frame member, said pivot intersecting said first axis, said second abutment and said first abutment being adapted to contact an article to be measured in the apparatus at spaced apart points along the peripheral surface thereof in the measurement of the ovality of the article; e. a third abutment mounted along said second axis on said second displaceable member for movement therewith and a fourth abutment which is separate from said second displaceable member and is mounted on said frame member and intersecting said second axis, said third abutment and said fourth abutment being adapted to contact an article to be measured at spaced apart points along the peripheral surface thereof for measuring the outer diameter of the article; f. a member mounted on said second displaceable member extending along said second axis of movement and defining a surface inclined 45* with respect to said second axis, and said inclined surface lying between said third and fourth abutments; and g. measuring means, having a sensing tip, mounted on said first displaceable member, said sensing tip arranged perpendicularly with Respect to said inclined surface and adapted to contact said surface, said measuring means having an indicating device associated with said sensing tip whereby a reading on the indicating device is related to the ovality of the article.
Claim 2
Dependent Claim
310 words
Apparatus for measuring the outer diameter and ovality of split ring out-of-round articles, comprising in combination: a. a frame member; b. a first displaceable member mounted on said frame member for movement along a first axis of movement; c. a second displaceable member mounted on said frame member for movement on a second axis different from said first axis; d. a first abutment mounted along said first axis on said first displaceable member for movement therewith and a second abutment which is separate from said first displaceable member and is pivotally mounted on said frame member, said pivot intersecting said first axis, said second abutment and said first abutment being adapted to contact an article to be measured in the apparatus at spaced apart points along the peripheral surface thereof in the measurement of the ovality of the article; e. a third abutment mounted along said second axis on said second displaceable member for movement therewith and a fourth abutment which is separate from said second displaceable member and is mounted on said frame member and intersecting said second axis, said third abutment and said fourth abutment being adapted to contact an article to be measured at spaced apart points along the peripheral surface thereof for measuring the outer diameter of the article; f. a member mounted on said second displaceable member extending along said second axis of movement and defining a surface inclined 45* with respect to said second axis, and said inclined surface lying between said third and fourth abutments; and g. measuring means, having a sensing tip, mounted on said first displaceable member, said sensing tip arranged perpendicularly with Respect to said inclined surface and adapted to contact said surface, said measuring means having an indicating device associated with said sensing tip whereby a reading on the indicating device is related to the ovality of the article.
Claim 3
Dependent Claim
67 words
Apparatus as defined in claim 1, further comprising another measuring means, with another indicating device and another associated sensing tip, mounted on said frame member, a pivotally mounted member on said frame member and contacted by said another sensing tip and said second displaceable member wherein a displacement of said second displaceable member is transmitted by direct contact with said pivotally mounted member to said sensing tip.
Claim 4
Dependent Claim
55 words
Apparatus as defined in claim 2, further including a fifth abutment mounted on said second displaceable member and said pivotally mounted member is contacted by said fifth abutment wherein a displacement of said second displaceable member along said second axis is transmitted by direct contact with said pivotally mounted member to said another sensing tip.
Claim 5
Dependent Claim
31 words
Apparatus as defined in claim 3, wherein said second abutment has two rollers rotatably mounted thereon to contact the peripheral surface of the article to be measured at spaced apart points.
Claim 6
Dependent Claim
29 words
Apparatus as defined in claim 4, wherein said second abutment has a projection which fits a gap defined between end portions of the split ring article to be measured.
Claim 7
Dependent Claim
45 words
Apparatus as defined in claim 4, wherein said indicating device and said another indicating device are electrically operated lamps which light up respectively when a split ring is not within settable tolerances of the ovality or diameter dimensions of the split ring size being checked.
Claim 8
Dependent Claim
48 words
Apparatus as defined in claim 4, further including a central lift-off means mounted on said frame member and arranged to cooperate with the first and second displaceable means for moving said first abutment and said third abutment into and out of contact with the article to be measured.
