Abstract: There is provided a bridge structure for a stringed instrument. A member supports a ridge over which the strings of the stringed instrument are strung. For each string, one end is secured at a location on the instrument which is remote from the member, the member supporting, for each string, a guide pulley around which the other end of the string passes. Means are provided for snagging the other end of the string, which means includes sub-means on the member whereby rotational torque is applied to the member. Suspension means are provided to support the member from the instrument body in such a way as to counteract that rotational torque.

Abstract: A stringed musical instrument, of the type in which the strings extend over a bridge which rests on the table of the instrument and are secured to a tailpiece, is provided with a tone improving device for maximising the tone production whatever strings are fitted to the instrument. The device is clamped to the table of the instrument and incorporates a nut to which the tailgut is attached. The nut is mounted on a threaded cylindrical member so as to be movable upwardly or downwardly on rotation of the member to modify the angle between the table and the part of the strings extending from the bridge to the tailpiece thereby to control the force exerted by the bridge on the table due to the tension in the strings without substantially varying the tension in the strings.

Abstract: An adjustable bridge for a stringed musical instrument is positionable at a selected position longitudinally of the strings of the instrument. The bridge is provided with a plurality of individually adjustable saddles which are mounted for movement in a direction longitudinally of the strings. Each saddle is provided with a dual height and composition insert. The bridge is of varying height laterally of the strings to provide for relatively uniform spacing from the instrument body.

Abstract: An attachment device for adjustably mounting the neck to the body of a stringed musical instrument, for example a banjo, has a pair of plates for attachment respectively to the neck and body of the banjo. A pivot point locates one plate with respect to the other, and a pair of adjustment screws interconnect the plates, cooperatively controlling the angle at which the neck extends away from the body. Elongated holes in one of the adapter plates receive the adjustment screws, permitting the neck to be rotated with respect to the body, about the longitudinal axis of the neck. The device may include a brace bar extending across the body of the instrument to hold a tailpiece. A setscrew opposes tension in the adjustment screws to hold the plates in desired relative positions.

Abstract: A floating bridge for string instruments arranged to generate a higher volume of responsive resonated sound, the floating bridge being mounted to a thin flexible wall of the instrument's resonant body, and the wall defining a flexible diaphragm. The bridge is secured to the associated strings and includes a bridge block having a clamping bar to hold each string in a fixed juxtaposed relation to the others, whereby the vibration of each string is transferred through the bridge and bridge-supporting post, or posts, so that the bridge is not subjected to the longitudinal tension of the strings, allowing the resultant vibrations therefrom to propagate to the hollow body of the instrument, without obstruction thereto.

Abstract: An integrated carrier/saddle structure for securing strings to an acoustic guitar which eliminates structural loading that inhibits the motion of the sounding board and provides adjustable coupling of the string vibrations to the diaphram formed by the guitar sounding board. The carrier member, to which the strings are attached, is mounted independently of the sounding board and is incorporated into the saddle structure through an aperture with an adjustment means being provided to vary the height of the carrier with respect to the saddle to optimize the coupling force between the strings and sounding board. A removable cover, attached to the saddle, is provided to enclose the aperture formed around the extension of the carrier member through the saddle structure and the adjustment mechanism.

Abstract: A panel having a rear wall is movably secured to the lower portion of a guitar body by a pair of screws allowing it to be moved toward and away from the guitar body. A sliding member is disposed in the panel under each guitar string, with a string contacting member secured on top of each slidable member and itself being slidable laterally thereon. Accordingly, guitar strings can be adjusted up and down the guitar, toward and away from the body, and across the fretboard, to thereby achieve optimum intonation and playability.

Abstract: A guitar bridge including a main body having adjustable support plates over which the guitar strings pass under tension. The main body of the guitar bridge is secured to an installation block which is, in turn, secured to the body of the guitar. The securement of the main body of the guitar bridge to the installation block is by way of an installation screw which is screwed into the support stand inside the body of the guitar. The upper end of the installation screw is domed and the receiving opening for the installation screw in the main body of the guitar bridge is correspondingly domed. A screw threaded extension up from the domed end of the installation screw is received by a tightening nut near the top of the guitar bridge and tightening of that nut on the extension of the installation screw tightens the installation screw into the domed opening in the guitar bridge main body.

Abstract: The bridge or tailpiece is fastened to the butt end of the sounding box of a stringed instrument, with a portion thereof projecting above the uppermost surface of the box, and with strings of the instrument being secured to the elevated portion. The tailpiece is adjustable for height relative to the upper surface of the box. The tailpiece may include adaptations which secure the strings at various levels above the box.

Abstract: A frame in which the body of a string instrument is supported, the frame having a main bar extending longitudinally in spaced relation to the back of the instrument body. The frame extends with end-pieces adapting to the ends of the said body, such end-pieces having clips applicable to the said ends by way of semi-hard inserts to dispose the body floatingly. One end-piece also extends with the neck and fret or string board of the instrument, while the other end-piece returns with a tail piece receiving the inner ends of the strings and formed as a bridge. The main bar is longitudinally adjustable for different lengths of instrument bodies.

Abstract: Disclosed are guitars having quick attach, quick release string securing mechanisms for use with string sets of measured lengths. A first embodiment of strings has loops formed on both ends, while a second embodiment of strings has a loop formed on one end and an anchor ball secured on the other. Each guitar disclosed has tuning mechanism including transversely extending string holding posts over which the string loops may be hooked. Guitars utilizing the first string embodiment have crosspiece structure carrying upwardly projecting posts around which the loops of the other strings ends can be hooked. The guitar utilizing the second string embodiment has crosspiece structure defining slotted rearwardly opening sockets for receiving the anchor balls secured on the other string ends. The string holding ends of each of the string holding posts are preferably formed as ball-shaped members and may be formed by screwing a ball on a treaded shaft.

Abstract: A unitary tailpiece is disclosed which supports a bridge assembly and which has top accessed sockets and slots adapted to anchor and hold the strings in proper position on a stringed instrument.

Abstract: A mute mechanism for an electric string bass or other stringed musical instrument is permanently mounted on the body of the instrument and includes a rubber faced mute movable into and out of engagement with the instrument's strings by a manually shiftable slide readily accessible by a performer playing the instrument.

Abstract: A compact adjustable bridge and string-anchoring structure for stringed musical instruments in the form of a bar whose top surface carries in juxtaposition bridge sections, one for each string, which are mounted for movement in a direction longitudinally of the strings and are equipped with means operable to vary their positions individually. Arranged in the front edge area of the bar are open anchoring recesses provided with small funnel-shaped apertures in their rear walls for the strings to pass through and emerge at the rear edge area of the bar while the beaded ends of the strings are retained and sheltered in the recesses. This rear edge area is smoothly rounded for the strings to be folded upwardly over said area into engagement with the individual bridge sections on the top surface of the bar.

Abstract: In a bridge for stringed instruments of the type including a plurality of independently movable drums which permit independent adjustment of the length and height of each string of the instrument, there is disclosed an improved construction wherein all of the drums are urged axially into contact with each other and a fixed post to reduce vibration of the drums and wherein the adjustment holes through the drums are arranged to prevent fraying of the sleeve of a player of the instrument as such sleeve passes over the bridge.
