Apparatus for measuring strand

Claim 1

An apparatus for accurately measuring moving wire passing through said apparatus in a forward direction comprising: a. a measuring wheel about the peripheral surface of which the wire passes in intimate frictional contact therewith at least once said wheel having a revolution counting mechanism associated therewith, b. a first contact roll tension assembly having at least two adjacent wire contacting rolls between which the wire passes in frictional contact therewith as it approaches said measuring wheel in a forward direction, c. means to continuously urge rotation of at least one of the rolls of the first contact roll assembly with a substantially constant force in a direction opposing passage of the wire, d. a second contact roll assembly having at least two adjacent wire contacting rolls between which the wire passes in frictional contact therewith after it passes around said measuring wheel in intimate contact therewith, e. means to prevent rotation of at least one of the rolls of said second contact roll assembly in a rearward direction while allowing free rotation of said rolls in a forward direction to allow forward passage of said wire, and f. prime mover means positioned after the measuring wheel but not before the second contact roll assembly to advance said wire in a forward direction around said measuring wheel and between said contact rolls.

Claim 2

An apparatus for accurately measuring moving wire passing through said apparatus in a forward direction comprising: a. a measuring wheel about the peripheral surface of which the wire passes in intimate frictional contact therewith at least once said wheel having a revolution counting mechanism associated therewith, b. a first contact roll tension assembly having at least two adjacent wire contacting rolls between which the wire passes in frictional contact therewith as it approaches said measuring wheel in a forward direction, c. means to continuously urge rotation of at least one of the rolls of the first contact roll assembly with a substantially constant force in a direction opposing passage of the wire, d. a second contact roll assembly having at least two adjacent wire contacting rolls between which the wire passes in frictional contact therewith after it passes around said measuring wheel in intimate contact therewith, e. means to prevent rotation of at least one of the rolls of said second contact roll assembly in a rearward direction while allowing free rotation of said rolls in a forward direction to allow forward passage of said wire, and f. prime mover means positioned after the measuring wheel but not before the second contact roll assembly to advance said wire in a forward direction around said measuring wheel and between said contact rolls.

Claim 3

An apparatus for accurately measuring moving wire passing through said apparatus in a forward direction comprising: a. a measuring wheel about the peripheral surface of which the wire passes in intimate frictional contact therewith at least once said wheel having a revolution counting mechanism associated therewith, b. a first contact roll tension assembly having at least two adjacent wire contacting rolls between which the wire passes in frictional contact therewith as it approaches said measuring wheel in a forward direction, c. means to continuously urge rotation of at least one of the rolls of the first contact roll assembly with a substantially constant force in a direction opposing passage of the wire, d. a second contact roll assembly having at least two adjacent wire contacting rolls between which the wire passes in frictional contact therewith after it passes around said measuring wheel in intimate contact therewith, e. means to prevent rotation of at least one of the rolls of said second contact roll assembly in a rearward direction while allowing free rotation of said rolls in a forward direction to allow forward passage of said wire, and f. prime mover means positioned after the measuring wheel but not before the second contact roll assembly to advance said wire in a forward direction around said measuring wheel and between said contact rolls.

Claim 4

An apparatus for accurately measuring moving wire passing through said apparatus in a forward direction comprising: a. a measuring wheel about the peripheral surface of which the wire passes in intimate frictional contact therewith at least once said wheel having a revolution counting mechanism associated therewith, b. a first contact roll tension assembly having at least two adjacent wire contacting rolls between which the wire passes in frictional contact therewith as it approaches said measuring wheel in a forward direction, c. means to continuously urge rotation of at least one of the rolls of the first contact roll assembly with a substantially constant force in a direction opposing passage of the wire, d. a second contact roll assembly having at least two adjacent wire contacting rolls between which the wire passes in frictional contact therewith after it passes around said measuring wheel in intimate contact therewith, e. means to prevent rotation of at least one of the rolls of said second contact roll assembly in a rearward direction while allowing free rotation of said rolls in a forward direction to allow forward passage of said wire, and f. prime mover means positioned after the measuring wheel but not before the second contact roll assembly to advance said wire in a forward direction around said measuring wheel and between said contact rolls.
