Centering device for electrical components

Claim 1

An apparatus for centering the uncentered bodies of electrical components each body having leads extending from opposite ends thereof, said apparatus comprising: first and second sections movable toward and away from each other for reception of said body therebetween; first and second means for varying the spacing between said sections, said first spacing varying means capable of providing a first spacing variation larger than a second spacing variation provided by said second spacing varying means; said first spacing varying means comprising a shaft having oppositely threaded equally spaced screw portions and threaded means in each of said sections for receiving one of said screw portions in a threaded relation having slack, and means for selectively rotating said shaft in opposite directions to open and close said spacing to a predetermined spacing of said sections; and said second spacing varying means comprising means for removing said slack in said threaded relation such that said spacing is widened relative to said predetermined spacing for reception of said body between said sections to prevent engagement of said sections with said body and said spacing is subsequently narrowed relative to said predetermined spacing to engage at least one of said sections with one of said uncentered body ends and center said component upon actuation of said slack removing means.

Claim 2

An apparatus for centering the uncentered bodies of electrical components each body having leads extending from opposite ends thereof, said apparatus comprising: first and second sections movable toward and away from each other for reception of said body therebetween; first and second means for varying the spacing between said sections, said first spacing varying means capable of providing a first spacing variation larger than a second spacing variation provided by said second spacing varying means; said first spacing varying means comprising a shaft having oppositely threaded equally spaced screw portions and threaded means in each of said sections for receiving one of said screw portions in a threaded relation having slack, and means for selectively rotating said shaft in opposite directions to open and close said spacing to a predetermined spacing of said sections; and said second spacing varying means comprising means for removing said slack in said threaded relation such that said spacing is widened relative to said predetermined spacing for reception of said body between said sections to prevent engagement of said sections with said body and said spacing is subsequently narrowed relative to said predetermined spacing to engage at least one of said sections with one of said uncentered body ends and center said component upon actuation of said slack removing means.

Claim 5

An apparatus for centering the uncentered bodies of electrical components each body having leads extending from opposite ends thereof, said apparatus comprising: first and second sections movable toward and away from each other for reception of said body therebetween; first and second means for varying the spacing between said sections, said first spacing varying means capable of providing a first spacing variation larger than a second spacing variation provided by said second spacing varying means; said first spacing varying means comprising a shaft having oppositely threaded equally spaced screw portions and means in each of said sections for threadedly receiving one of said screw portions and means for selectively rotating said shaft in opposite directions to open and close said spacing to a predetermined spacing of said sections; and said second spacing varying means comprising a sleeve having an external bearing portion telescopically received in each section and a threaded internal portion providing said screw portion receiving means, and means for telescoping said sections inward and outward relative to said sleeves such that said spacing is widened relative to said predetermined spacing for reception of said body between said sections to prevent engagement of said sections with said body, and said spacing is subsequently narrowed relative to said predetermined spacing to engage at least one of said sections with one of said uncentered body ends and center said component.

Claim 6

An apparatus for centering the uncentered bodies of electrical components each body having leads extending from opposite ends thereof, said apparatus comprising: first and second sections movable toward and away from each other for reception of said body therebetween; first and second means for varying the spacing between said sections, said first spacing varying means capable of providing a first spacing variation larger than a second spacing variation provided by said second spacing varying means; said first spacing varying means comprising a shaft having oppositely threaded equally spaced screw portions and means in each of said sections for threadedly receiving one of said screw portions and means for selectively rotating said shaft in opposite directions to open and close said spacing to a predetermined spacing of said sections; and said second spacing varying means comprising a sleeve having an external bearing portion telescopically received in each section and a threaded internal portion providing said screw portion receiving means, and means for telescoping said sections inward and outward relative to said sleeves such that said spacing is widened relative to said predetermined spacing for reception of said body between said sections to prevent engagement of said sections with said body, and said spacing is subsequently narrowed relative to said predetermined spacing to engage at least one of said sections with one of said uncentered body ends and center said component.
