Abstract
Abstract The centering mechanism and method described herein are used for locating objects with respect to a center line or to a center. The mechanism includes opposed centering members for engaging opposite sides of an article to be centered so as to grip the article as a part of an assembly including a gauging element which is differentially positioned in accordance with the measured dimension of the article. The assembly is then moved with the article in a given direction to engage the gauging element with a stop at which time any article within a given range of sizes will be located in position with its center on a center line previously determined or with its center at a center point which has been previously determined.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
101 words
In a center or center line locator, a pair of centering elements mounted for movement to grip an article therebetween, a gauge setting member, means pivotally mounting said member on a movable plate, one of said centering elements having means moving said member, a second gauge setting member movable with the other of said centering elements, a gauge element controlled by both of said gauge setting members means responsive to the movement of both of said setting members moving said gauge element to a position corresponding to a center or center line position of an article engaged between said centering elements.
Claim 2
Dependent Claim
101 words
In a center or center line locator, a pair of centering elements mounted for movement to grip an article therebetween, a gauge setting member, means pivotally mounting said member on a movable plate, one of said centering elements having means moving said member, a second gauge setting member movable with the other of said centering elements, a gauge element controlled by both of said gauge setting members means responsive to the movement of both of said setting members moving said gauge element to a position corresponding to a center or center line position of an article engaged between said centering elements.
Claim 3
Dependent Claim
78 words
In a center or center line locator as recited in claim 1, in which the gauge element comprises a pin or roller, a movably mounted lever carrying the pin or roller, and in which the first gauge-setting member comprises Means on the first centering element and engageable with the free end of said lever, and the second gauge setting member comprises an element movable with said second centering element for moving the lever bodily with its mounting means.
Claim 4
Dependent Claim
76 words
In a center or center line locator as recited in claim 1, in which the gauge element comprises a freely movable pin, in which the first gauge setting member comprises means providing a first inclined cam slot, and in which the second gauge setting member comprises a second means providing a second inclined cam slot in intersecting relation with said first slot, the cam slots engaging said pin and being movable respectively with said centering elements.
Claim 5
Dependent Claim
75 words
In a center or center line locator as recited in claim 1, in which the gauge element comprises a pinion, translationally movable mounting means upon which the pinion is journaled, and in which the respective gauge setting members comprise racks connected respectively to said centering elements and both engaged with said pinion but on opposite sides thereof, and means mounting said racks for movement parallel to the movement of the mounting means for said pinion.
Claim 6
Dependent Claim
91 words
In a centering device, a frame, a center indicating a gauge element mounted for movement on said frame, and a pair of opposite centering elements movable with respect to each other and said gauge element and being operative to engage an article positioned therebetween, each of said centering elements having means related thereto and to said gauge element, said last mentioned means responsive to relative movement between said elements to control the position of said indicating element to indicate a dimensional measurement of the article as measured by said centering elements.
Claim 7
Dependent Claim
91 words
In a centering device, a frame, a center indicating a gauge element mounted for movement on said frame, and a pair of opposite centering elements movable with respect to each other and said gauge element and being operative to engage an article positioned therebetween, each of said centering elements having means related thereto and to said gauge element, said last mentioned means responsive to relative movement between said elements to control the position of said indicating element to indicate a dimensional measurement of the article as measured by said centering elements.
Claim 8
Dependent Claim
147 words
In a center or center line locator, a base, a pair of opposed article centering elements mounted for movement on said base, said centering elements being responsive to an article engaged therebetween to space said centering elements apart differentially in accordance with and in proportion to a selected dimension of the article, a stop on said base, and a mechanism responsive to the differential positioning of one of said centering elements in accordance with the selected dimension of the article, said mechanism including a gauge element, means differentially positioning said gauge element with respect to said stop so that said gauge element bears a fixed geometrical relation to the center line of the article, whereby engagement of said gauge element with said stop positions the article and the centering elements with reference to a center line with the center of the article positioned on the center line.
Claim 9
Dependent Claim
147 words
In a center or center line locator, a base, a pair of opposed article centering elements mounted for movement on said base, said centering elements being responsive to an article engaged therebetween to space said centering elements apart differentially in accordance with and in proportion to a selected dimension of the article, a stop on said base, and a mechanism responsive to the differential positioning of one of said centering elements in accordance with the selected dimension of the article, said mechanism including a gauge element, means differentially positioning said gauge element with respect to said stop so that said gauge element bears a fixed geometrical relation to the center line of the article, whereby engagement of said gauge element with said stop positions the article and the centering elements with reference to a center line with the center of the article positioned on the center line.
