Abstract: A stringed musical instrument employs springs to apply tension to corresponding musical strings. Each spring is chosen and configured for its ability to impart a string tension generally matched to the appropriate tension of the string at perfect tune. Preferably, the spring is selected and arranged so that the tension in the string maintains at or near perfect tune even as the string elongates or contracts over time. In one embodiment, once a string is placed in appropriate tune, a mechanical visual indicator is set. As such, if tune of the string changes due to string elongation or contraction, the change is reflected by misalignment of the mechanical visual indicator even if the change cannot be aurally detected. Perfect tune can be reestablished by realigning the indicator. In another embodiment, a force modulating member is interposed between a spring and its corresponding musical string.

Abstract: Disclosed is a guitar string tuning device.

Abstract: A machine head for guitars is disclosed. In the machine head, the tension of a string is adjusted by sequentially rotating a manually operated adjusting knob, a worm engaging with the knob, a worm wheel engaging with the worm, and a winding peg integrated with the worm wheel with the string wound on or unwound from the winding peg. A cap guider is formed on the top end of the winding peg, while a string holding cap is rotatably fitted over the cap guider of the winding peg, thus being brought into a rotatable engagement with the guider. In an embodiment, the guider has upper and lower guide discs integrated at both ends of an eccentric shaft, while the cap has two string insert holes on its sidewall at eccentric positions. When the winding peg is rotated with a string passing through the two string insert holes, the string is firmly jammed at the junction between the eccentric shaft and the sidewall of the string holding cap.

Abstract: A tuning peg incorporates an internal planetary gear reduction mechanism so that a stringed instrument, such as the cello, violin or viola, can be easily and precisely tuned. In order to change the pitch of a string, the head of each peg is rotated which in turn rotates the carrier that holds the string. Turning the head drives a toothed input shaft that runs the entire length of peg. The input shaft engages and rotates a plurality of planetary gears that engage a ring gear that is affixed to the peg box. Thus, rotation of the head rotates the carrier that changes the tension on the string, but the number of turns of the head required to rotate the carrier once is a multiple of one so that the carrier can be rotated more easily and the instrument can be tuned more precisely.

Abstract: This invention is directed to a ukelele that is relatively simple yet sturdy in construction, produces a superior tone, is easy to hold and play, easy to tune, remains in tune for extended periods of time, and is useful in teaching people to play stringed instruments of the type where the strings are plucked to produce a musical tone. The sound box, in plan view, is constructed in the shape of a right angle triangle. The sound box has three circular sound openings positioned in a triangular pattern on the top surface of the sound box. The neck of the ukelele extends a substantial distance into the sound box. The strings of the ukelele pass through two sets of holes in the tuning head before being wound onto the tuning pegs.

Abstract: A tuning peg for a musical instrument such as a banjo, guitar, or the like in which the tone of the string is determined by the tension thereon, the tuning peg having two coaxial parts with inclined surfaces therebetween so that as the string tends to rotate the tuning peg, the inclined surfaces push the portions apart, causing increased frictional contact, which in turn resists rotation. In addition, a gear linkage within the tuning peg multiplies the effect of the torque which further resists rotation by the taut string.

Abstract: A head piece, for grasping by a musician, having a stem joined thereto, the stem having elongated teeth which are formed thereon and disposed radially with respect to the longitudinal axis of the stem and head piece. A ratchet body having a bore therethrough is placed over a spindle, and the spindle is threaded into the head piece such that the spindle and head piece are rotatable as a unit. The ratchet body has elongated teeth formed thereon which are radially disposed about the bore of the ratchet body and which mesh with the teeth formed on the stem. The meshing teeth allow rotation of the head piece and spindle in one direction only with respect to the ratchet body, thereby causing a string of a musical instrument attached to the spindle to be wound about the spindle and secured in a taut condition.
