Lead straightening machine

Claim 1

A device for straightened thin deformable end members projecting from the ends of body members of articles of manufacture comprising a frame, a pair of spaced straightening shoes having smooth concave surfaces, means supporting said straightening shoes, said means supporting said shoes comprising a tension spring having one end attached to each said shoe and the other end of each said spring attached to a block on said frame, spaced straightening rollers rotatably supported on said frame, means rotating said rollers, said rollers peripheral surface generally conforming to the said concave surface, an adjustment screw fixed to each said block and engaging each said block whereby the force of said spring on said block and the clearance between said rollers and said shoes may be adjusted, means to feed articles having deformable wirelike end members projecting from their ends, said means comprising a feeding chute, said feeding chute comprising two upper plates spaced form each other and two lower plates spaced from each other and spaced from said upper plates and defining a groove between said upper plates ans said lower plates through which said wirelike end members may pass, a body wheel disposed at the lower end of said upper plates and said lower plates, said upper plate having a lower end with a surface overlying said body wheel, said lower end surface of said upper plates having a radius of curvature substantially equal to the radius of said body wheel, the outer periphery of said body wheel being disposed adjacent the outer periphery of said straightening rollers and between said straightening shoes, spaced notches in the outer periphery of said body wheel adapted to receive the bodies of said articles and to carry said articles from said space between said upper plates and said lower plates to said straightening rolls and to deposit said articles in the space between said straightening rolls and said straightening shoes.

Claim 2

A device for straightened thin deformable end members projecting from the ends of body members of articles of manufacture comprising a frame, a pair of spaced straightening shoes having smooth concave surfaces, means supporting said straightening shoes, said means supporting said shoes comprising a tension spring having one end attached to each said shoe and the other end of each said spring attached to a block on said frame, spaced straightening rollers rotatably supported on said frame, means rotating said rollers, said rollers peripheral surface generally conforming to the said concave surface, an adjustment screw fixed to each said block and engaging each said block whereby the force of said spring on said block and the clearance between said rollers and said shoes may be adjusted, means to feed articles having deformable wirelike end members projecting from their ends, said means comprising a feeding chute, said feeding chute comprising two upper plates spaced form each other and two lower plates spaced from each other and spaced from said upper plates and defining a groove between said upper plates ans said lower plates through which said wirelike end members may pass, a body wheel disposed at the lower end of said upper plates and said lower plates, said upper plate having a lower end with a surface overlying said body wheel, said lower end surface of said upper plates having a radius of curvature substantially equal to the radius of said body wheel, the outer periphery of said body wheel being disposed adjacent the outer periphery of said straightening rollers and between said straightening shoes, spaced notches in the outer periphery of said body wheel adapted to receive the bodies of said articles and to carry said articles from said space between said upper plates and said lower plates to said straightening rolls and to deposit said articles in the space between said straightening rolls and said straightening shoes.

Claim 9

A device for axially straightening elongated articles of the type having a large body portion and thin deformable end members projecting from each end comprising, in combination, a frame, a guiding track mounted thereon, a shaft journaled in said frame and spaced from and parallel to said track, a pair of rollers constituting the only means of moving the articles through the device, means mounting said rollers for angular movement with said shaft and relatively axial adjustment therealong, a shoe mount associated with each roller and movable on said track, a pressure shoe for each shoe mount, means universally mounting each pressure shoe on a respective shoe mount for small rectilinear and angular movements in all directions with respect thereto, said pressure shoe having a concave surface spaced slightly from, and conforming substantially to the curvature of the surface of its associated roller, whereby said shoes and rollers may be adjusted to the length of said body portion and substantially the entire end members may be subjected to straightening action between said rollers and said shoes, a body wheel supported to rotate on an axis disposed parallel to the axis of rotation of said rollers, said body wheel having spaced notches therein, means to feed said articles bodies into said notches, said body wheel having means to rotate to deposit said bodies between said rollers and said shoes.

Claim 10

A device for axially straightening elongated articles of the type having a large body portion and thin deformable end members projecting from each end comprising, in combination, a frame, a guiding track mounted thereon, a shaft journaled in said frame and spaced from and parallel to said track, a pair of rollers constituting the only means of moving the articles through the device, means mounting said rollers for angular movement with said shaft and relatively axial adjustment therealong, a shoe mount associated with each roller and movable on said track, a pressure shoe for each shoe mount, means universally mounting each pressure shoe on a respective shoe mount for small rectilinear and angular movements in all directions with respect thereto, said pressure shoe having a concave surface spaced slightly from, and conforming substantially to the curvature of the surface of its associated roller, whereby said shoes and rollers may be adjusted to the length of said body portion and substantially the entire end members may be subjected to straightening action between said rollers and said shoes, a body wheel supported to rotate on an axis disposed parallel to the axis of rotation of said rollers, said body wheel having spaced notches therein, means to feed said articles bodies into said notches, said body wheel having means to rotate to deposit said bodies between said rollers and said shoes.
