Apparatus for preparing wire for drawing

Claim 2

In apparatus for preparing wire continuously for drawing as the wire is pulled by wire drawing apparatus to the receiving end of said wire drawing apparatus; a. means supplying cleaned wire axially of its length substantially continuously, b. a first electrically conductive sheavelike member having a pair of sheave grooves with one sheave groove in position to receive and support said cleaned wire as it passes relative thereto, c. a second electrically conductive sheavelike member mounted in spaced relation to and insulated electrically from said first sheavelike member and disposed to receive and support said wire after said wire passes around said one sheave groove of said first sheavelike member and deliver said wire to the other sheave groove of said first sheavelike member, d. means applying a coating to said wire adjacent said first sheavelike member and between said first and second sheavelike members, e. means passing an electrical current through said first and second sheavelike members so that current passes through said wire while said wire is supported and in motion between said sheavelike members heating said wire to a temperature to bake said coating thereon, and f. means delivering said wire with said coating baked thereon to said receiving end of the wire drawing apparatus whereby the wire is pulled around said sheavelike members and then through said wire drawing apparatus.

Claim 3

Apparatus for preparing wire for drawing as defined in claim 1 in which at least one of said sheavelike members is operatively connected to a centrifugal-type switch which is deenergized while there is no rotation of said sheavelike members and said switch is in circuit with said means passing an electrical current through said wire whereby the passage of current through said wire is interrupted while there is no rotation of said sheavelike members.

Claim 4

In apparatus for preparing wire continuously for drawing as the wire is pulled by wire drawing apparatus to the receiving end of said wire drawing apparatus: a. at least one endless belt extending transversely of said wire and having an outer abrasive surface engaging said wire, b. a support member mounted for rotation about said wire, c. pulleys mounted for rotation on said support member at opposite sides of said wire receiving and supporting the ends of said endless belt, d. a centrally disposed gear having an opening therethrough for passing said wire axially of its length, e. a gear operatively connected to each said pulley and in mesh with said centrally disposed gear, f. means imparting relative rotary movement between said centrally disposed gear and the other gears whereby said pulleys are rotated in the same direction to impart movement to said belt as said support member, said pulleys and said endless belt rotate about said wire so that cleaned wire is supplied substantially continuously, g. a first sheavelike member mounted in position to receive and support said cleaned wire as it passes relative thereto, h. a second sheavelike member mounted in spaced relation to said first sheavelike member and disposed to receive and support said wire after said wire passes around said first sheavelike member, i. means applying a coating to said wire between said first and second sheavelike members, j. means passing an electrical current through said wire while said wire is supported and in motion between said sheavelike members heating said wire to a temperature to bake said coating thereon, and k. means delivering said wire with said coating baked thereon to said receiving end of the wire drawing apparatus wHereby the wire is pulled around said sheavelike members and then through said wire drawing apparatus.

Claim 5

In apparatus for preparing wire continuously for drawing as the wire is pulled by wire drawing apparatus to the receiving end of said wire drawing apparatus: a. at least one endless belt extending transversely of said wire and having an outer abrasive surface engaging said wire, b. a support member mounted for rotation about said wire, c. pulleys mounted for rotation on said support member at opposite sides of said wire receiving and supporting the ends of said endless belt, d. a centrally disposed gear having an opening therethrough for passing said wire axially of its length, e. a gear operatively connected to each said pulley and in mesh with said centrally disposed gear, f. means imparting relative rotary movement between said centrally disposed gear and the other gears whereby said pulleys are rotated in the same direction to impart movement to said belt as said support member, said pulleys and said endless belt rotate about said wire so that cleaned wire is supplied substantially continuously, g. a first sheavelike member mounted in position to receive and support said cleaned wire as it passes relative thereto, h. a second sheavelike member mounted in spaced relation to said first sheavelike member and disposed to receive and support said wire after said wire passes around said first sheavelike member, i. means applying a coating to said wire between said first and second sheavelike members, j. means passing an electrical current through said wire while said wire is supported and in motion between said sheavelike members heating said wire to a temperature to bake said coating thereon, and k. means delivering said wire with said coating baked thereon to said receiving end of the wire drawing apparatus wHereby the wire is pulled around said sheavelike members and then through said wire drawing apparatus.

Claim 6

Apparatus for preparing wire for drawing as defined in claim 3 in which said centrally disposed gear and said support member are mounted on a power driven, hollow shaftlike member.

Claim 7

Apparatus for preparing wire for drawing as defined in claim 3 in which a takeup is anchored at one end to said support member with the other end of said takeup bearing against the inner surface of one flight of said endless belt urging the other flight thereof into engagement with said wire.
