Apparatus and method for control of wire cast and helix

An apparatus for controlling the helix characteristic of wire drawn from a wire source by means for pulling the wire, said apparatus comprising:

• means, located between the wire source and the means for pulling the wire, for guiding the pulled wire in a first plane,
• means, located between said guide means and the means for pulling the wire, for selectively shifting the pulled wire from the first plane to a second plane, whereby the helix characteristic of the wire is selectively controlled, wherein said plane shifting means include an assembly comprised of a sheave and a movable block,
• wherein said assembly is comprised of:
• a sheave including means for guiding the pulled wire in a selected second plane, said sheave further including an opening oriented substantially perpendicular to the second plane,
• a movable block supporting said sheave, said movable block including an opening aligned with the opening in said sheave,
• means for guiding the movement of said movable block,
• a fastener passing through the opening in said sheave and the opening in said movable block for fixing said sheave to said movable block.

An apparatus for controlling the helix characteristic of wire drawn from a wire source by means for pulling the wire, said apparatus comprising:

• means, located between the wire source and the means for pulling the wire, for guiding the pulled wire in a first plane,
• means, located between said guide means and the means for pulling the wire, for selectively shifting the pulled wire from the first plane to a second plane which is parallel to said first plane, whereby the helix characteristic of the wire is selectively controlled,
• wherein said plane shifting means includes:
• an assembly comprised of a sheave and a movable block, and
• means for selectively adjusting the location of said assembly,
• wherein:
• said assembly includes a hollow bolt securing said sheave to said movable block and said movable block includes an orifice extending from said hollow bolt to the bottom of said movable block,
• said selective adjustment means include,
• a threaded shaft,
• a handwheel connected to said threaded shaft,
• a stationary block having threads complementary to said threaded shaft, and
• a threaded adjustment nut located on said threaded shaft below said movable block,
• wherein said handwheel is connected to said threaded shaft and is capable of turning said shaft, and
• wherein said threaded shaft passes through said hollow bolt, said sheave, said movable block, said adjustment nut, and said stationary block, whereby by turning said handwheel said threaded shaft is selectively moved up or down with respect to said stationary block, and said adjustment nut respectively pushes said assembly up or permits said assembly to ride down, whereby said sheave is selectively moved outside the first plane.

• means, located between the wire source and the means for pulling the wire, the guiding the pulled wire in a first plane, said guide means including means for selectively imparting a cast to the wire,
• means, located between said guide means and the means for pulling the wire, the selectively shifting the pulled wire from the first plane to a second plane, whereby the helix characteristic of the wire is selectively controlled,
• wherein said plane shifting means includes an assembly comprised of a sheave and a movable block and means for selectively adjusting the location of said assembly,
• further including a shim placed between said sheave and said movable block to provide clearance between said sheave and said movable block.

An apparatus for controlling the cast and the helix characteristics of wire drawn from a wire source by means for pulling the wire, said apparatus comprising:
