PLAYING BAR FOR ELECTRIC STRINGED MUSICAL INSTRUMENTS Filed June 29, 1964 INVENTORS 5 E M 5R & a Ma m 0 6 V f 0 United States Patent Calif.
Filed June 29, 1964, Ser. No. 378,894 7 Claims. (Cl. 84319) This invention relates to a guitar playing bar generally used in playing the Hawaiian guitar and more particularly to a bar for use with electric stringed musical instruments in which the bar includes manually adjustable volume and tone controls integral therewith.
In modern electric stringed musical instrument playing techniques some instruments are used in which induction or similar types of pickup devices are held in proximity to the strings. The pickup devices are connected to electronic or transistor amplifiers which in turn feed their output to loudspeakers. In the prior art volume control devices connected to the amplifiers were incorporated in the stringed instrument body and required specialized manipulative techniques to operate them taking up finger activity which could be useful in playing on the strings if not so taken up with the volume adjustments. A later prior art development provides foot pedal volume controls and tone controls which did then free the players hands.
However, the competition among entertainers who play these electric stringed instruments led to the development of a variety of tonal color variation controls which were actuated by foot pedals and this relegated the volume and tone function controls back to the guitar body. Players who had become accustomed'to the pedal tone and volume controls and who were now returning to the use of finger controls have been seeking a way to still retain the foot pedal tonal color controls without having to return the volume and tone control functions to the guitar body for manipulation with the fingers needed for plucking the strings.
We have devised a means for overcoming this difficulty by the use of the bar used in playing the stringed electric musical instrument usually, particularly the steel or Hawaiian guitar in which the sliding of the bar along the frets on the neck of the guitar produces the familiar glissando tones associated with the Hawaiian guitar.
This invention contemplates a fret bar for Hawaiian guitars and similar electric stringed musical instruments which is properly weighted and in the top surface of which there is operatively inserted a volume control which can be manipulated with the index finger of the instrument player without any diversion from the actual playing operations. In the side of this same bar is inserted another control for tone adjustment which may be manipulated with the players thumb also without any diversion from the actual playing operations.
Accordingly, it is an object of this invention to provide a fret bar for electric stringed musical instruments wherein a volume control and tone control are made an integral part thereof and which controls can be manipulated respectively by the players index finger and thumb.
It is a further object of this invention to provide a fret bar for electric stringed musical instruments wherein volume and tone controls are permanently installed therein for finger manipulation while sliding the bar along the frets for playing the guitar to provide independent volume and tone adjustment while utilizing other tone color pedals and the like.
It is a still further object of this invention to provide a fret bar for Hawaiian guitar playing which has a volume control so inserted therein that it may be adjusted Patented July 13, 1965 "ice with the index finger and a tone control so inserted therein it may be adjusted with the thumb, both adjustments being possible independently or simultaneously while moving the bar along the frets during the playing of a musical number.
It is another object of this invention to provide finger operable volume and tone controls in a fret bar for guitars whereby the fret bar may be electrically connected by a cable to a stringed musical instrument amplifier and volume and tone of the musical performance adjusted continuously without interruption of the playing sequence and permitting greater virtuosity in playing to be displayed thereby.
These and other objects of the invention will become more clear from the specification which follows in which a single and preferable embodiment of the invention is disclosed. It is not to be construed however, as the sole implementation of the invention, in that others skilled in this art, in the light of this disclosure and the appended claims, may conceive other implementations of the invention within the ambit of the claims which follow, taken together with the accompanying drawings in which:
FIGURE 1 is a side elevational view of the article of this invention showing in phantom internal details thereof;
FIGURE 2 is a cutaway view in part of the article of this invention showing in further detail the parts indicated in FIGURE 1;
FIGURE 3 is an end view from the rear of the article;
FIGURE 4 is a representative circuit diagram of the controls such as may be used in the article shown in the preceding figures; and
FIGURE 5 is a perspective view of the article showing it in use on a guitar fret board in the hand of the player.
Referring now to FIGURES 1, 2 and 3 taken together the fret bar of this invention may be seen to consist of a housing which is generally solid but is machined out in interior portions to accommodate the installation of internal elements as described below.
On a transverse axis 11 near the front of housing 10 a volume control unit 12 is mounted inside the housing 10. Volume control 12 is equipped with terminals 13,
14, 15 to which wires may be attached for connection thereof to appropriate external circuits.
The wires 17 comprising a two wire shielded cable are typical of a wire connection that may be made to the unit 12 and a thin control knob 18 of such diameter that it projects above the surface of the housing 10 as may be seen at 19 is concentrically mounted on volume control 12 and tightly afiixed thereto so that when knob 18 is pushed by a finger on the outside of. housing 10 as may be seen at 20 in FIGURE 5 control 12 will be rotated. Itshould be noted here that control 12 though small in size is a conventional type of potentiometer volume control device wherein a variable contact arm is rotated upon a resistance element to vary potential applied to an external amplifying device connected to the variable arm 14 by one of the wires 17. The potential source is a signal derived from electric instrument string pickups and is applied through wires inside the shield thereof to terminal 15 of control 12. The terminal 13 is connected to the shielded portion of wire 17 forming the potential ground return.
011 a vertical axis 21 in the mid portion of housing 12 a tone control 22 is mounted. Control 22 has terminals thereon at 23, 24 and 25. Terminal 23 is connected to terminal 15 of control 12. Terminal 24 of control 22 is connected to one terminal of tone capacitor 26 in an amplifier 28 connected with an electric stringed musical 3 instrument such as 237, only the fret board on the neck thereof being shown in FIGURE 5.
In FIGURE 4 a typical schematic connection is shown of the two controls 12 and 22 (numbered exactly as in the illustrations of FIGURES l and 2 and showing the electrical symbols for the potentiometers used for tone 22 and volume 12 control and their connection by wires 17 to amplifier 2% Tone control 22 in series with capacitor 26 connect effectively in parallel with volume control 12. Tone control 22 is connected as a rheostat. In this way only two wires, 14a, 35 and a shield 37 making cable 17 are necessary to connect article 10 to an instrument 27.
From the preceding description and particularly from the illustration shown in FIGURE 5 the operation and construction of the volume and tone control bearing fret bar iii of this invention can readily be seen.
When using the bar 10 which is generally a solid housing milled out to accommodate the controls 12 and 22 and knobs l3 and 29, the player moves the fret bar along strings 33 on fret board 27 of a guitar adjusting volume with his forefinger or index finger 2-9 by rotating knob 18 back and forth and adjusting tone with his thumb 3%} by rotating knob 29 back and forth as the musical requirements of the performance or players preference dictates.
