Abstract
Abstract Apparatus especially suitable for paying off wire from a cored bundle or coil or wire positioned eye-up on a skid or a pallet. The apparatus includes a hat member consisting of a plate with a centrally disposed crown adapted to be positioned with the plate resting on the upper surface of the coil and the crown fitting into the eye of the coil. Holddown rods are provided which are anchored at their bottom ends to the skid or pallet with their upper ends passing through the crown of the hat member when the apparatus is positioned on a coil of wire. Helical coil springs surround the portion of each of the rods above the crown and a wing nut threaded on the upper end of each rod holds the spring in compression so that the crown of the hat member is constantly urged inwardly of the eye of the coil of wire. A spindle extends centrally from the bottom of the crown to a point above the plate of the hat member. A spinner payoff mechanism is rotatably mounted on the spindle and a brake is provided for controlling the speed of rotation of the spinner payoff mechanism.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
231 words
In a coil of strand material resting with its eye directed vertically on a base support and having a sleeve lining its eye the improvement therewith of apparatus for uncoiling said coil, said apparatus comprising a rigid hat member including a plate and an integral crown disposed centrally of said plate, said plate being adapted to rest on the top of said coil with said crown fitting in the eye of the coil, elongated spring-loaded means resiliently anchoring said crown to said base support, said means constantly urging said crown inwardly of the eye of said coil, a centrally disposed fixed spindle projecting upwardly of said crown and plate, a spinner payoff mechanism rotatably mounted on said spindle, said spinner mechanism having a radially extending first arm disposed with the free end thereof adjacent the periphery of said coil, the free end of said first arm having an eyelet therethrough for passage of said strand material, said spinner mechanism having a substantially vertical second arm, said second arm having an eyelet in the free end thereof for the passage of strand material therethrough after said strand material passes through said first mentioned eyelet, the free end portion of said radially extending arm of said spinner mechanism being adapted to rotate about the periphery oF said coil as strand material is drawn from said coil through said first and second mentioned eyelets.
Claim 2
Dependent Claim
231 words
In a coil of strand material resting with its eye directed vertically on a base support and having a sleeve lining its eye the improvement therewith of apparatus for uncoiling said coil, said apparatus comprising a rigid hat member including a plate and an integral crown disposed centrally of said plate, said plate being adapted to rest on the top of said coil with said crown fitting in the eye of the coil, elongated spring-loaded means resiliently anchoring said crown to said base support, said means constantly urging said crown inwardly of the eye of said coil, a centrally disposed fixed spindle projecting upwardly of said crown and plate, a spinner payoff mechanism rotatably mounted on said spindle, said spinner mechanism having a radially extending first arm disposed with the free end thereof adjacent the periphery of said coil, the free end of said first arm having an eyelet therethrough for passage of said strand material, said spinner mechanism having a substantially vertical second arm, said second arm having an eyelet in the free end thereof for the passage of strand material therethrough after said strand material passes through said first mentioned eyelet, the free end portion of said radially extending arm of said spinner mechanism being adapted to rotate about the periphery oF said coil as strand material is drawn from said coil through said first and second mentioned eyelets.
Claim 3
Dependent Claim
33 words
Apparatus as defined by claim 1 including adjustable brake means on said spindle in contact with said spinner mechanism effective to exert frictional force on said spinner mechanism and thereby control its rotation.
Claim 4
Dependent Claim
106 words
Apparatus as defined by claim 2 in which said spinner mechanism includes a hub, said arms being connected to and projecting from said hub, said spindle being formed with a flange intermediate its ends, said hub resting on said flange, said brake means including a nut threaded on the upper end of said spindle and a helical coil spring circumferentially disposed around the portion of said spindle bearing against said nut and said hub, said nut being adjustable along said spindle to thereby increase and decrease the compression of said spring on said hub for increasing and decreasing the friction between said hub and said flange.
Claim 5
Dependent Claim
60 words
Apparatus as defined by claim 1 in which said elongated spring-loaded means includes at least a pair of rods each having a nut threaded on its upper end, a helical spring surrounding the portion of said rod between said crown and said nut, and means on the bottom of said rod engaging said support base to anchor the rod thereto.
Claim 6
Dependent Claim
22 words
Apparatus as defined by claim 1 in which said plate is formed with radially extending closed end slots spaced about its periphery.
Claim 7
Dependent Claim
16 words
Apparatus as defined by claim 1 in which said crown is formed with viewing ports therethrough.
