Abstract
Abstract A wire payout assembly that fits over the upper end of a drum of wire to prevent coils and groups of coils that come out of the drum from reaching a wire winding machine. The wire leaves the drum along an inner cone that holds loops of wire substantially horizontal as they unwind. Successively smaller diameter turns of tubing in an outer cone cause any groups of coils to pull apart into individual coils that unwind more easily. Guiding means at the top of the outer cone lead the wire to a winding machine or other use location.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
184 words
A payout assembly for a wire drum package incLuding in combination a frame having a lower end that supports the assembly with its vertical axis in substantial alignment with the axis of a drum containing a coil of wire that is to be payed out from said coil, a portion of the height of the frame being tapered and having successively higher turns of tubing with the successive turns of smaller diameter for contact with random coils of wire that may pass upward in a group of coils and by said contact to separate the group into individual coils that will pull out into straight runs of wire, an inner element within the frame and substantially coaxial therewith, the lower portion of said inner element having a diameter that fits into a wire drum core with which the payout assembly is intended to be used, and the upper portion of the inner element tapering toward its upper end to prevent any substantial shifting of loops of wire into other planes after the loops of wire leave the drum and move upwardly in the frame.
Claim 2
Dependent Claim
184 words
A payout assembly for a wire drum package incLuding in combination a frame having a lower end that supports the assembly with its vertical axis in substantial alignment with the axis of a drum containing a coil of wire that is to be payed out from said coil, a portion of the height of the frame being tapered and having successively higher turns of tubing with the successive turns of smaller diameter for contact with random coils of wire that may pass upward in a group of coils and by said contact to separate the group into individual coils that will pull out into straight runs of wire, an inner element within the frame and substantially coaxial therewith, the lower portion of said inner element having a diameter that fits into a wire drum core with which the payout assembly is intended to be used, and the upper portion of the inner element tapering toward its upper end to prevent any substantial shifting of loops of wire into other planes after the loops of wire leave the drum and move upwardly in the frame.
Claim 3
Dependent Claim
42 words
The payout assembly described in claim 1 characterized by the successive turns of tubing being separate hoops made of smooth tubing, and vertically-extending elements of the frame that hold the hoops in spaced relation to one another with vertical spacing between them.
Claim 4
Dependent Claim
63 words
The payout assembly described in claim 1 characterized by the successive turns of tubing being convolutions of a helical tube that extends around the axis of the vertical frame, the convolutions of the helical tube being held in position by other parts of the frame including vertically extending elements secured to convolutions of the helix at angularly spaced locations around the respective convolutions.
Claim 5
Dependent Claim
128 words
The payout assembly described in claim 1 characterized by a guide at the upper end of the frame including a tube in substantial alignment with the axis of the drum and frame, and through which the wire passes, the guide also including a grooved pulley for changing the direction of run of the wire, and another tube through which the wire passes after traveling around an arc of the pulley, the inside radius of the guide tubes being approximately equal to the radius of the cross-section of the pulley groove, and the ends of the guide tubes being so located so as to bring the wire back into the pulley groove when the wire comes out of the groove as the result of slack accumulation in the wire.
Claim 6
Dependent Claim
51 words
The payout assembly described in claim 1 characterized by the lower end of the frame having radially spaced surfaces that fit over the inside and outside of a top rim of a wire-containing drum for supporting the frame from the drum and for holding the frame in alignment with the drum.
Claim 7
Dependent Claim
59 words
The payout assembly described in claim 5 characterized by the lower end of the frame having a groove therein facing downwardly and of a diameter to fit over the top rim of the wire-containing drum, the radially spaced surfaces of the groove being the surfaces that fit over the inside and outside of the top rim of the drum.
Claim 8
Dependent Claim
47 words
The payout assembly described in claim 1 characterized by the inner element having a frusto conical ouside surface that decreases in diameter as it extends upward to prevent the loops of wire from becoming tight around the inner element as they travel upward and decrease in diameter.
Claim 9
Dependent Claim
45 words
The payout assembly described in claim 7 characterized by the lower end portion of the inner element being cylindrical, a wire drum core into which the cylindrical portion of the inner element fits at the center of a coil of wire contained within the drum.
Claim 10
Dependent Claim
62 words
The payout assembly described in claim 1 characterized by the inner element within the frame having its upper portion made of a sheet material tubular construction around which loops of wire pass upwardly from the drum as the loops unwind to straight runs, the upper portion of the inner element terminating below the top of the turns of tubing of the frame.
Claim 11
Dependent Claim
96 words
The payout assembly described in claim 9 characterized by the lower portion of the inner element including a ring at its uppeR end of an outside diameter to fit into the lower end of the sheet material that forms the upper portion of the inner element, the lower end of the sheet material being cut lengthwise at close angularly spaced locations around its circumference to form tabs that are bent around the ring from the outside thereof and secured to the ring to connect the upper portion of the inner element to the lower portion thereof.
Claim 12
Dependent Claim
53 words
The payout assembly described in claim 9 characterized by the turns of tubing of the frame and the surfaces of the tapered inner element, with which the wire contacts either usually or occasionally, having smooth surfaces and being free of roughness of welds and other protusions on which loops of wire could catch.
