US4581976A — Reinforced musical instrument string

Claim 1

Independent Claim 154 words

A musical instrument string adapted to be mounted on a musical instrument having a string anchor and a bridge comprising: a core wire having a looped end and a twisted segment adjacent the loop end, said looped end adapted to be received by said string anchor when the string is mounted on the musical instrument; and a wrap wire of smaller diameter than said core wire wound tightly around the twisted segment of the core wire, the length of core wire wound by the warp wire being a small fraction of the overall length of the core wire and lying entirely between said string anchor and said bridge when the string is mounted on the musical instrument, whereby the musical string enables a reinforced mounting connection to be made with a string instrument without affecting the harmonic vibrations of the string due to the vibrational isolation of the reinforced connection provided by the bridge.

Claim 2

Dependent Claim 154 words

A musical instrument string adapted to be mounted on a musical instrument having a string anchor and a bridge comprising: a core wire having a looped end and a twisted segment adjacent the loop end, said looped end adapted to be received by said string anchor when the string is mounted on the musical instrument; and a wrap wire of smaller diameter than said core wire wound tightly around the twisted segment of the core wire, the length of core wire wound by the warp wire being a small fraction of the overall length of the core wire and lying entirely between said string anchor and said bridge when the string is mounted on the musical instrument, whereby the musical string enables a reinforced mounting connection to be made with a string instrument without affecting the harmonic vibrations of the string due to the vibrational isolation of the reinforced connection provided by the bridge.

Claim 3

Dependent Claim 27 words

The musical instrument string defined in claim 1, additionally comprising a substantially spool shaped cylinder held within the loop at the looped end of the core wire.

Claim 4

Dependent Claim 25 words

The musical instrument string defined in claim 1, wherein the length of core wire wound by the wrap wire is no more than one inch.

Claim 5

Dependent Claim 43 words

The musical instrument string defined in claim 1, wherein the end of the wrap wire remote from the looped end of the core wire is trimmed close to the core wire so as to not provide any sharp edges to a person's touch.

Claim 6

Dependent Claim 166 words

A musical instrument string providing a reinforced attachment to a musical instrument of the type having a string anchor and a bridge at a first end and a tuning key and nut at a second end, the linear distance between said bridge and said nut defining a vibration length, the instrument string comprising: a core wire, bent a short distance from one end thereof, wherein the end segment of the core wire is twisted together with a segment of the core wire remote from the end, so that the core wire has a looped end and a twisted segment adjacent the looped end; and a warp wire of smaller diameter than said core wire wound tightly around the twisted segment of the core wire, wherein the length of the core wire wound with the wrap wire is a small fraction of the overall length of the core wire and forms no part of said vibration length when the instrument string is placed on said musical instrument.

Claim 7

Dependent Claim 166 words

A musical instrument string providing a reinforced attachment to a musical instrument of the type having a string anchor and a bridge at a first end and a tuning key and nut at a second end, the linear distance between said bridge and said nut defining a vibration length, the instrument string comprising: a core wire, bent a short distance from one end thereof, wherein the end segment of the core wire is twisted together with a segment of the core wire remote from the end, so that the core wire has a looped end and a twisted segment adjacent the looped end; and a warp wire of smaller diameter than said core wire wound tightly around the twisted segment of the core wire, wherein the length of the core wire wound with the wrap wire is a small fraction of the overall length of the core wire and forms no part of said vibration length when the instrument string is placed on said musical instrument.

Claim 8

Dependent Claim 51 words

The musical instrument string defined in claim 5 wherein the twisted segment of the core wire terminates in a tip or tail segment, wherein the tail segment extends alongside the core wire, substantially parallel the core wire and forms part of said length of core wire wound with the wrap wire.

Claim 9

Dependent Claim 16 words

The musical instrument string defined in claim 5, wherein the core wire has a circular cross-section.

Claim 10

Dependent Claim 37 words

The musical instrument string defined in claim 5, additionally comprising a cylinder having an annular groove formed in its outer surface, wherein the cylinder is fitted within the loop of the looped end of the core wire.

Claim 11

Dependent Claim 170 words

A string for a musical instrument, the musical instrument comprising a body having a string anchor and a bridge and with a pre-selected vibration length, the string comprising: a first wire having a base end adapted to be attached to the string anchor of the musical instrument so the string can be pulled taut across the bridge, wherein the distance along the first wire from the anchor to the bridge defines a first length of the first wire; and a wrap comprising a second wire of smaller diameter than said first wire spirally wound on a segment of the first wire near the base end to form a wrapped segment of the first wire, the wrapped segment having a second length, wherein the second length is shorter than the first length, so the wrapped segment of the first wire does not pass over the bridge when the string is attached to the string anchor and pulled taut across the bridge and thus does not form part of said vibration length.

Claim 12

Dependent Claim 170 words

A string for a musical instrument, the musical instrument comprising a body having a string anchor and a bridge and with a pre-selected vibration length, the string comprising: a first wire having a base end adapted to be attached to the string anchor of the musical instrument so the string can be pulled taut across the bridge, wherein the distance along the first wire from the anchor to the bridge defines a first length of the first wire; and a wrap comprising a second wire of smaller diameter than said first wire spirally wound on a segment of the first wire near the base end to form a wrapped segment of the first wire, the wrapped segment having a second length, wherein the second length is shorter than the first length, so the wrapped segment of the first wire does not pass over the bridge when the string is attached to the string anchor and pulled taut across the bridge and thus does not form part of said vibration length.

Claim 13

Dependent Claim 31 words

The musical instrument string defined in claim 9, wherein the end of the second wire is trimmed close to the first wire so as to be smooth to a person's touch.
