Q 42 J go I 1%NffO/B ,4 TTORNEY Patented Oct. 22, 1929 UNITE STATES HERMAN C. J. HAGIBERG, F BERKELEY, CALIFORNIA ATTACHMENT FOR STRINGEI) MUSICAL INSTRUMENTS Application filed August 31,1926. Serial No. 132,724.,
My invention relates to a means for supporting the strings in violins and similar stringed instruments.
It is primarily the object of my invention to reduce string breakage in musical instru ments. It was found, in accomplishingthis object that a marked improvement in the tone of the instrument resulted, and it therefore becomes a further object of my invention to improve the tonal quality of existing types of stringed instruments.
It is an object of my invention to provide a device producing either or both these improvements in stringed instruments, and
which device may be furnished as an attachment applicable to existing instruments.
My invention further aims at the accomplishment of the above results in a simple inexpensive manner, and with an attachment which may be easily applied.
Other and ancillary objects will be suggested in the following specification and further by the uses to which my invention will be put.
I will describe my invention as applied to a violin, but it will be understood that a cello, banjo, mandolin, or any of a large number of stringed instruments other than the violin might have been selected for illustration.
Referring to the drawings:
Figures 1 to 4 are fragmentary views of the portion of a violin to which my attachment is applicable. Fig. 1 is a plan view showing my attachment applied to the head portion of the violin; Fig. 2 is a longitudinal elevation of the head and adjacent neck portions; and Figs. 8 and 4 are median longitudinal vertical sections of two different forms of my attachment in a violin. Figs. 5 and 6 are respectively perspective and front elevation detail views of the form of attachment illustrated in Fig. 4; while Fig. 7 is a perspective detail of the form of my attachment illustrated in Fig. 3.
In a stringed musical instrument in general, and in a violin in particular, the strings 2, 4, 6 and 8 arestretched (under determined- 1y adjusted tension) above or spaced from the sounding board or body 9 of the instrument over and between supporting rests or bridges 10 and. 11, so that the portion 12 of each string between the points of support is free to vibrate and produce a musical tone, which tone may be adjusted by altering the tension of the strings. In the present instance the bridge or rest 10 constitutes the nut at the head end of the finger board. The strings are tensed by means of the pegs 14, 16, 18 and 20, rotatably retained in holes in the peg box 22 provided at the head of the instrument, and tapered so they may be wedged against rotation in said holes. When the pegs are rotated to wind thereon the strings 2, 4, 6 and 8, they impart tension to the strings. It will be noted that the peg box is appreciably below the vibratory portion 12 of the strings, and therefore in violins not fitted with my attachment 24, a sharp angle is defined in each string at the rest 10. The sharpness of this angle produces a'high pressure upon this bridge 10, and is the cause of frequent string breakage. Especially in the case of the steel string 8, a high localized pressure is produced at 10 whichis believed to be the cause of damping the resonant qualities of all but the most finely constructed violins. I am not certain of the cause, but the marked improvement of tone quality which results from the use of my attachment is unmistakable.
This attachment 24, of my invention in its simplest form (see Figs. 1, 2. 3 and 7 comprises a substantially plane-bottomed block long enough to straddle the peg box 22 and seat upon the upper edges of its side walls 26 and 28. This block is made high enough to'bear against the strings and relieve the rest 10 of the major portion of the pressure imposed thereupon by the said strings. The upper face of this hearing block-24 is curved and is wide enough to iron out the former sharp angle at 10 into a smooth curve of large radius. In simplest'form, the string grooves 30, 32, 34 and 36 in the block 24, are substantially of the same depth, and the curvature of the upper surface is made such asto merely distribute the bearing area of the strings over a broader surface to prevent cutting the strings and to avoid undue localization of pressure on the instrument. The height of the block is adjusted to take approximately four-fifths of the pressure imposed by the strings; leaving the remaining one-fifth pressure on the rest 10. Evidently then, this member 24 forms an auxiliary string rest or support which is arranged to be compressedly engaged between the strings and head. The bottom surface of the block 24 has a thin piece 38, of leather, fabric, paper or other yielding or suitable material glued to it to facilitate its attachment to the instrument with an adhesive. This material 38, which may be easily abraded away, also forms a convenient means for adjusting the height of the bearing block or auxiliary rest 24. When it is desired to accurately adjust the rate of curvature of each string from the point 10 to its tapered peg 14, 16, 18, or 20, the effective curvature of the upper surface of the auxiliary rest 24 must be complex, (i. e. curved in two directions; i. e. a solid curve as distinguished from a planar curve) This eifect may be achieved by varying the depth of one end of the several string grooves, as shown in Figs. 4, 5, and 6 as at 30. The curvature of each of these grooves 30, 32, 34 and 36 would be made to approximate a circular are described from the point 10 to the respective pegs 14, 16, 18 and 20.
Figs. 4, 5 and 6 also represent a modified means for securing the auxiliary rest 24 to the violin. A depending leg 40 serves to attach the bridge 24 to the end-wall 42 of the pe -box; the leg being narrow enough to fit between the sidewalls 26 and 28. The planar back face of this leg 40 is glued to the end wall 42, and the tip of the leg may be long enough to seat against the bottom of the peg box and relieve the side walls of pressure from the main porton of the bearing block 24.
Other modifications within the purview of my invention will suggest themselves in the application of my device to violins and to other stringed instruments. I wish therefore not to be circumscribed beyond the limits set by the claims.
I claim:
1. In combination with a stringed musical instrument of the type having a string tensed across a pair of main bridges with a portion of said string extended in a substantially straight line to a string-holding means spaced beyond said bridges, said string portion lying opposite a non-resonant instrument portion, an auxiliary member immovably fixed to said instrument between said holding means and the main bridge nearest thereto; said member being constructed and positioned to assume a portion of the pressure of said string and being acoustically insulated from the instrument portion engaged thereby.
2. In combination with a violin, a broad string-supporting member mounted on the head of said violin between the string-tens ing pegs and the vibratory portion of the strings; the string-supporting surface of said member being gradually curved to approximate tangency with said vibratory portion of the strings on the one side and with a line drawn to a string-tensing peg on the other side.
3. An attachment for violins having strings tensed at a substantial angle over a main supporting bridge by tensing means spaced out of line with the vibratory portion of said strings, comprising an auxiliary string support member having a broad gradually curved string-supporting surface, and means for attaching said auxiliary member to said violin at the non-vibratory string portions; said attachment being constructed to position the string-supporting surface thereof in approximate tangency with a line drawn to said tensing means on the one side and with a line drawn tangent to said main supporting bridge on the other side.
In testimony whereof, I aliix my signature.
