Abstract
Abstract A tailpiece and bridge assembly for a stringed musical instrument, comprising a housing attachable to the body of the instrument at the tailpiece. The housing having a pivot axle extending across it. A respective pivot lever for each of the instrument strings being pivotable about the pivot axle between a position toward the body and an upraised position. A string end securing body supported on the pivot lever and screw threadedly adjustable in position therealong for adjusting the tension of the string. A saddle disposed between the pivot axle and the string securing body, and upon the lever being lowered, the string wraps about the top of the saddle, initially tensioning it. A latch on each lever releasably latches the lever to the housing.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
208 words
A tailpiece and bridge assembly for a stringed musical instrument, comprising: a plurality of pivot levers, each pivot lever adapted to receive a respective string; means supported on the body of the instrument for defining pivots for the pivot levers, each pivot lever extending toward the rear of the stringed instrument from its pivot, each said pivot lever being independently pivotable on its pivot with respect to the other pivot levers between a position substantially toward the body of the instrument and a pivoted position upraised from the body of the instrument; securing means on each pivot lever and spaced rearwardly from the pivot therefor, to which a respective string may be secured; the securing means on the lever being movable along the lever selectively rearwardly and forwardly of the guitar body for selectively adjusting the tension of the string; and bridge saddle means disposed on the body of the instrument rearwardly on the instrument of the pivots for the levers, and the levers extending rearwardly of the bridge saddle means; the bridge saddle means being forward on the instrument body of the securing means for the strings on the levers; the bridge saddle means including a top section over which the strings for the instrument can pass.
Claim 2
Dependent Claim
208 words
A tailpiece and bridge assembly for a stringed musical instrument, comprising: a plurality of pivot levers, each pivot lever adapted to receive a respective string; means supported on the body of the instrument for defining pivots for the pivot levers, each pivot lever extending toward the rear of the stringed instrument from its pivot, each said pivot lever being independently pivotable on its pivot with respect to the other pivot levers between a position substantially toward the body of the instrument and a pivoted position upraised from the body of the instrument; securing means on each pivot lever and spaced rearwardly from the pivot therefor, to which a respective string may be secured; the securing means on the lever being movable along the lever selectively rearwardly and forwardly of the guitar body for selectively adjusting the tension of the string; and bridge saddle means disposed on the body of the instrument rearwardly on the instrument of the pivots for the levers, and the levers extending rearwardly of the bridge saddle means; the bridge saddle means being forward on the instrument body of the securing means for the strings on the levers; the bridge saddle means including a top section over which the strings for the instrument can pass.
Claim 3
Dependent Claim
41 words
The tailpiece assembly of claim 1, further comprising releasable latch means for latching each pivot lever in the position toward the instrument body, and the latch means being releasable for enabling the lever to be pivoted away from the instrument body.
Claim 4
Dependent Claim
36 words
The tailpiece assembly of claim 1, wherein the support for the pivots comprises a housing in which all of the pivot levers are seated when the pivot levers are at their position toward the instrument body.
Claim 5
Dependent Claim
52 words
The tailpiece assembly of claim 3, further comprising latch means on the housing of the tailpiece assembly, and the latch means being for latching the pivot lever in the position toward the instrument body, and the latch means being releasable for enabling the lever to be pivoted away from the instrument body.
Claim 6
Dependent Claim
90 words
The tailpiece assembly of claim 4, wherein the latch means for the pivot lever comprises a step formed on the housing and a cooperating projection supported by the lever and so placed that the projection contacts the step as the lever is moved toward the instrument body; upon the projection contacting the step, the projection passes the step and becomes latched to the step; biasing means for urging the step and projection into engagement such that the projection is latched behind the step once the projection has passed the step.
Claim 7
Dependent Claim
56 words
The tailpiece assembly of claim 5, wherein the latch means comprises a tiltable element supported by the lever and tiltable against the bias of the biasing means for separating the projection and the step, and for releasing the latching of the pivot lever for permitting the pivot lever to be pivoted away from the instrument body.
Claim 8
Dependent Claim
26 words
The tailpiece assembly of claim 3, further comprising means on each lever for moving the securing means of the string along the length of the lever.
Claim 9
Dependent Claim
94 words
The tailpiece assembly of claim 7, wherein the securing means comprises a body to which the string is secured and the body being movable along the length of the lever and being supported on the lever, the body having a threaded bore therein, a screw extending into and mating with the bore in the movable body and the screw being supported to the housing for remaining substantially axially stationary as the rotatable screw is rotated, whereby rotation of the screw moves the movable body along the length of the lever for adjusting string tension.
Claim 10
Dependent Claim
62 words
The tailpiece assembly of claim 3, wherein the housing includes a rear wall which is located rearwardly of the securing means securing the strings to the pivot levers, the rear wall having notches therein through which the rear portions of the pivot levers extend and the notches being shaped for maintaining the orientations of the pivot levers against side to side motion.
Claim 11
Dependent Claim
22 words
The tailpiece assembly of claim 1, wherein the height of the bridge saddle means is adjustable with respect to the instrument body.
Claim 12
Dependent Claim
39 words
The tailpiece assembly of claim 1, further comprising a musical instrument string which is attachable to the securing means on the lever and which extends from the securing means over, past and in contact with the bridge saddle means.
Claim 13
Dependent Claim
26 words
The tailpiece assembly of claim 1, further comprising means on each lever for moving the securing means of the string along the length of the lever.
Claim 14
Dependent Claim
59 words
The tailpiece assembly of claim 12, wherein the means for moving the securing means comprises rotatable means supported to the lever and comprises a screw connection between the rotatable means and the securing means, and the screw connection therebetween being such that upon rotation of the rotatable means, the securing means for the string is movable along the lever.
Claim 15
Dependent Claim
103 words
The tailpiece assembly of claim 13, wherein the securing means comprises a body to which the string is secured and the body being movable along the length of the lever and being supported on the lever, the screw connection comprises the body having a threaded bore therein, the rotatable means comprising a screw extending into and mating with the bore in the movable body and the screw being supported to the support means for remaining substantially axially stationary as the rotatable screw is rotated, whereby rotation of the screw moves the movable body along the length of the lever for adjusting string tension.
Claim 16
Dependent Claim
59 words
The tailpiece assembly of claim 1, wherein the height of the top of the bridge saddle means is selected to be higher off the instrument body than the height of the securing means so that as each pivot lever is lowered toward the instrument body, the string contacts the top of the bridge saddle means and is bent therearound.
