Abstract
Abstract A wire tangle sensor is disclosed for sensing tangled wire in a wire fabrication process prior to being fed into a wire drawing machine so that a tangled wire signal may be sent to a verbal annunciator. A verbal announcement of a tangled wire condition is made for immediate corrective action by maintenance personnel to avoid a production shutdown. The wire tangle sensor comprises a metallic probe positioned in close proximity to a moving wire which touches the wire when it becomes tangled thereby grounding the probe and providing a current path for a switch which initiates the verbal announcement.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
84 words
A wire tangle sensor, comprising: an elongated metallic probe for placement in close proximity to grounded wire payed out from a coil in a basket, said probe for touching tangled wire, said touching causing the grounding of said probe; and signalling means, connected to said probe, responsive to said touching of said metallic probe to a tangled wire for causing a current to be conducted through said probe and said grounded wire and for providing a tangle signal indicative of a tangled wire condition.
Claim 2
Dependent Claim
84 words
A wire tangle sensor, comprising: an elongated metallic probe for placement in close proximity to grounded wire payed out from a coil in a basket, said probe for touching tangled wire, said touching causing the grounding of said probe; and signalling means, connected to said probe, responsive to said touching of said metallic probe to a tangled wire for causing a current to be conducted through said probe and said grounded wire and for providing a tangle signal indicative of a tangled wire condition.
Claim 3
Dependent Claim
103 words
A wire tangle sensor, for use with a verbal annunciator actuated by a signalling means, comprising: a pair of elongated guide rollers for positioning above a basket of grounded wire for guiding wire payed out from the basket; and an elongated metallic probe for connection to the signalling means and for placement parallel to said elongated guide rollers in close proximity to payed out wire guided by said guide rollers, for touching a tangle in wire which is payed out from the basket in a tangled manner thereby grounding the probe to actuate the signalling means for causing actuation of the verbal annunciator.
Claim 4
Dependent Claim
