Abstract
Abstract A fretted neck of a guitar having a plurality of strings spaced above the fretboard and slide bar apparatus that includes a tubular portion having a first end, a second end axially opposite the first end, a finger receiving chamber opening through the first end and a frusto conical outer surface having a major base remote from the first end, a cap portion integrally joined to the second end and having a curved outer surface, and a rolled length of plastic film in the finger receiving chamber that may be cut off to provide for selectively sizing the effective opening of the finger receiving chamber to a given user''s finger.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
97 words
For playing a guitar, slide bar apparatus comprising an axially elongated tubular portion having a first end, a second end axially opposite the first end, a finger receiving chamber opening through the first end and an outer frusto conical surface that diverges away from the tubular portion central axis in an axial direction toward the second end, said tubular portion further having a circular cylindrical inner surface defining said finger receiving opening and having provided in said chamber a rolled length of plastic film having a width about equal to the axial length of the tubular portion.
Claim 2
Dependent Claim
97 words
For playing a guitar, slide bar apparatus comprising an axially elongated tubular portion having a first end, a second end axially opposite the first end, a finger receiving chamber opening through the first end and an outer frusto conical surface that diverges away from the tubular portion central axis in an axial direction toward the second end, said tubular portion further having a circular cylindrical inner surface defining said finger receiving opening and having provided in said chamber a rolled length of plastic film having a width about equal to the axial length of the tubular portion.
Claim 3
Dependent Claim
72 words
For facilitating playing a guitar having strings and a fretted neck, slide bar apparatus comprising an axially elongated tubular portion having a first end, a second end axially opposite the first end and a finger receiving chamber opening through the first end and a cap portion integrally joined to said tubular portion second end, said tubular portion having a frusto conicaL outer surface that has a major base adjacent said cap portion.
Claim 4
Dependent Claim
72 words
For facilitating playing a guitar having strings and a fretted neck, slide bar apparatus comprising an axially elongated tubular portion having a first end, a second end axially opposite the first end and a finger receiving chamber opening through the first end and a cap portion integrally joined to said tubular portion second end, said tubular portion having a frusto conicaL outer surface that has a major base adjacent said cap portion.
Claim 5
Dependent Claim
29 words
The apparatus of claim 2 further characterized in that said frusto conical surface is tapered at an angle of about 2*-5* relative the central axis of said tubular portion.
Claim 6
Dependent Claim
30 words
The apparatus of claim 2 further characterized in that said cap portion has an outer surface having a radius of curvature of greater than one-half of the major base dimension.
Claim 7
Dependent Claim
28 words
The apparatus of claim 2 further characterized in that the axial length of said tubular portion is greater than twice the maximum transverse dimension of said tubular portion.
Claim 8
Dependent Claim
90 words
For facilitating playing a guitar having strings and a fretted neck, slide bar apparatus comprising an axially elongated tubular portion having a first end, a second end axially opposite the first end and a finger receiving chamber opening through the first end, a cap portion integrally joined to said tubular portion second end, and a rolled length of plastic film within the finger receiving chamber, said plastic film having a width approximately the same as the axial length of the tubular portion and a length substantially greater than its width.
Claim 9
Dependent Claim
90 words
For facilitating playing a guitar having strings and a fretted neck, slide bar apparatus comprising an axially elongated tubular portion having a first end, a second end axially opposite the first end and a finger receiving chamber opening through the first end, a cap portion integrally joined to said tubular portion second end, and a rolled length of plastic film within the finger receiving chamber, said plastic film having a width approximately the same as the axial length of the tubular portion and a length substantially greater than its width.
Claim 10
Dependent Claim
25 words
The apparatus of claim 6 further characterized in that the axial length of the tubular portion is at least twice the maximum transverse dimension thereof.
Claim 11
Dependent Claim
91 words
For playing a guitar, slide bar apparatus comprising an axially elongated metal tubular portion having a first end, a second end axially opposite the first end, a finger receiving chamber opening through the first end and an outer frusto conical surface that diverges away from the central axis in an axial direction toward the second end, and a metal cap portion integrally joined to the second end having an outer surface that has a general radius of curvature at least equal to the major base dimension of the frusto conical surface.
Claim 12
Dependent Claim
91 words
For playing a guitar, slide bar apparatus comprising an axially elongated metal tubular portion having a first end, a second end axially opposite the first end, a finger receiving chamber opening through the first end and an outer frusto conical surface that diverges away from the central axis in an axial direction toward the second end, and a metal cap portion integrally joined to the second end having an outer surface that has a general radius of curvature at least equal to the major base dimension of the frusto conical surface.
Claim 13
Dependent Claim
47 words
The apparatus of claim 8 further characterized in that the tubular portion has a circular cylindrical inner surface defining said finger receiving opening and that there is provided a rolled length of plastic film having a width about equal to the axial length of the tubular portion.
