Patent number: 4607511Abstract: A method and apparatus for controlling the gauge of a product, such as for example a rod or bar, as the product is passing from an upstream roll stand to a finishing block. The product is rolled under tension between successive sizing stands arranged between the upstream roll stand and the finishing block. Variable loops are introduced in the product between the upstream stand and the first sizing stand as well as between the second sizing stand and the finishing block. Cross sectional dimensional measurements are taken of the product emerging from the second sizing stand, and signals representative of such measurements are employed by a controller to vary the product tension between the sizing stands in order to correct off gauge conditions in the product emerging from the second sizing stand.Type: GrantFiled: April 26, 1985Date of Patent: August 26, 1986Assignee: Morgan Construction CompanyInventor: Terence M.

Patent number: 4604883Abstract: A mass flow control system for a wire drawing machine wherein wire is drawn through a die by a rotating block driven by a variable speed motor. The thus drawn wire is accumulated as a plurality of windings on the block before being removed therefrom via a guide. The guide is arranged on a carrier ring which rotates independently of the block about the axis of block rotation when a difference exists between the rates at which wire is wound onto and removed from the block. The control system includes a motion detector for generating electrical signals representative of the direction and speed of rotation of the carrier ring. Controls associated with the drive motor and responsive to the aforesaid signals adjust the rotational speed of the block in order to reach a steady state condition where wire is being wound onto and removed from the block at the same rate, and the carrier ring remains motionless.Type: GrantFiled: October 17, 1985Date of Patent: August 12, 1986Assignee: Morgan Construction CompanyInventors: William R.

Patent number: 4586720Abstract: A seal for use on the tapered section of a roll neck in a rolling mill. The seal has a flexible circular body with a circular lip and a circular flange at one end thereof. The lip extends axially from the body and the flange extends radially from the body and normal or perpendicular with respect to the body axis when the seal is in an unstressed condition. The seal is adapted to be axially received on and to be radially stressed by the tapered roll neck section with an accompanying radial expansion of the lip which produces a circumferential bending moment tending to angularly distort the flange from its perpendicular orientation to the seal axis. An internal circular shoulder on the seal body, coacts with the tapered roll neck section to counteract the bending moment and thereby prevent distortion of the flange.Type: GrantFiled: January 23, 1985Date of Patent: May 6, 1986Assignee: Morgan Construction CompanyInventors: Thomas E. Simmons, Ralph F. Divirgilio, Charles L. Innis, Jr.

Patent number: 4580353Abstract: A conveyor has successive mutually spaced driven rollers in which hot rolled steel rod is transported in the form of overlapping offset rings. The rings are rapidly air cooled by first nozzles which direct first jets of cooling air upwardly to impinge against and to flow around the conveyor rollers, and by second nozzles which direct second jets of cooling air upwardly between the rollers. The first and and second jets of cooling air produce respective first and second velocity profiles, each having an average velocity. The arrangement of the first and second nozzles in relation to each other and to the conveyor rollers is such that the velocity profiles of the first and second jets are superimposed one over the other to produce a broader combined velocity profile having an average velocity greater than that of either the first or second velocity profiles.Type: GrantFiled: October 31, 1984Date of Patent: April 8, 1986Assignee: Morgan Construction CompanyInventors: Asjed A.
