Abstract
Abstract A tuning peg for a stringed musical instrument comprises a cylindrical housing adapted to be mounted on a stringed musical instrument. The housing has a central chamber, an axially extending slot and a shearing surface. A slider is positioned within the central chamber and has a key projecting into the slot for allowing the slider to move axially relative to the housing and for preventing rotation of the slider relative to the housing. One end of the slider has a transverse aperture for receiving a string, a screw for clamping the string in the aperture and a shearing surface proximate to the aperture and the shearing surface on the housing. A knob is threaded on the other end of the slider. The knob is rotatable relative to the housing but is prevented from axial movement relative to the housing such that rotation of the knob moves the slider in the axial direction to tune the string and shear the string between the shearing surfaces.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
187 words
A tuning machine for mounting on a guitar headstock, comprising: elongated housing means for extending substantially through the headstock of the guitar substantially perpendicular thereto, including a shearing surface, a bearing surface, and a slot aligned with a string of the guitar and extending in an axial direction from the bearing surface into the housing means for allowing the string to slidably move therein; holding means slidably positioned in the housing means for moving longitudinally in the housing means, including an aperture substantially aligned with the direction of the string on the guitar for receiving the string therein, means for securing the string in the aperture substantially in alignment throughout its length with the direction of the string on the guitar, the string having an end portion which exits the aperture, and the holding means also including another shearing surface; and tuning means for moving the holding means longitudinally relative to the housing means and simultaneously drawing the string into the slot over the bearing surface and shearing the end portion of the string between the shearing surfaces without rotating the holding means in the housing means.
Claim 2
Dependent Claim
187 words
A tuning machine for mounting on a guitar headstock, comprising: elongated housing means for extending substantially through the headstock of the guitar substantially perpendicular thereto, including a shearing surface, a bearing surface, and a slot aligned with a string of the guitar and extending in an axial direction from the bearing surface into the housing means for allowing the string to slidably move therein; holding means slidably positioned in the housing means for moving longitudinally in the housing means, including an aperture substantially aligned with the direction of the string on the guitar for receiving the string therein, means for securing the string in the aperture substantially in alignment throughout its length with the direction of the string on the guitar, the string having an end portion which exits the aperture, and the holding means also including another shearing surface; and tuning means for moving the holding means longitudinally relative to the housing means and simultaneously drawing the string into the slot over the bearing surface and shearing the end portion of the string between the shearing surfaces without rotating the holding means in the housing means.
Claim 3
Dependent Claim
21 words
The machine as claimed in claim 1, wherein the holding means includes screw means for clamping the string in the aperture.
Claim 4
Dependent Claim
19 words
The machine as claimed in claim 1, wherein the tuning means includes a knob threaded on the holding means.
Claim 5
Dependent Claim
46 words
The machine as claimed in claim 3, wherein the housing means includes a housing surrounding the holding means, the housing and the holding means extending in the axial direction, and wherein a substantial portion of the knob surrounds and overlaps the housing in the axial direction.
Claim 6
Dependent Claim
31 words
The machine as claimed in claim 1, wherein the housing means includes a housing surrounding the holding means and wherein the housing and the holding means extend in the axial direction.
Claim 7
Dependent Claim
