STRlNG ED MUSICAL INSTRUMENT.
SPECIFICATION forming part of Letters Patent N 0. 703,572, dated July 1, 1902. Application filed March 29,1902. Serial No. 100,520- (No model.)
To aZl whmn it may concern:
Be it known that I, KARL GRIENAUER, a citizen of Austria-Hungary,and a resident of New York city, county and State of New York,have invented certain new and useful Improvements in Stringed Musical Instruments, of
which the following is a specification.
This invention relates to a stringed musical instrument so constructed that the resonating-chamber is placed under transverse tension in addition to the longitudinal tension imparted by the strings. By this transverse tension the quantity as well as the quality of the tone is greatly improved.
In the accompanying drawings, Figure l is a perspective view of a Violoncello provided with my improvement; Fig. 2, a cross-section on line 2 2, Fig. 1. Figs. 3 to 5 are details of the brace and nut, and Fig. 6 a cross-section of a modification.
The letter a represents the belly, Z) the back, and c the sides, of the resonating-chamber of a stringed musical instrument, such as a violin, viola, Violoncello, or bass.
The strings d subject the belly a and back b to high longitudinal tension, but not to transverse tension. In order to also subject them to transverse tension, I fit into the reso- Dating-chamber a number of transverse braces 6, extending in planes'at right angles to the strings. These braces are arranged, preferably, diagonally, as shown in Fig. 2, extending from one upper point to the transverselyopposite lower point. Along one edge of the resonating-chamber the usual bead f is slotted or mutilated for the accommodation of a nut g, which is of oblong shape and forms, in effeet, a part or continuation of the bead, Fig. 3. This nut engages the outwardly-extend ing threaded end ofth'e brace e, and by turning it the brace may be placed under any strain desired toimpart acorresponding transverse tension to the belly and back. Underneath the nut g'a reinforcing-plate h may be fitted. Along the other edge of the resonating-chamber the bead is also cutaway to accommodate a correspondingly-shaped plate 2' for engaging the headed end of the brace. By the construction described the nut g is exposed and accessible from the outer side of the instrument, so that the tension may be readily adjusted from the exterior of the resonating-chamber.
In Fig. 6 the diagonal braces c are replaced by parallel transverse braces j, extending from one side 0 to the opposite side 0. These sides are provided with perforated reinforcing-strips 7a, through which the braces pass and which prevent the braces from tearing through or collapsin g the sides. In this modification the nuts for adjusting the tension of the braces are likewise mounted upon the exposed ends of the same at the exterior of the resonating-chamber.
It will be seen that by my invention the belly and back are placed under transverse tension in addition to the longitudinal tension caused by the strings. In this'way the entire resonating-chamber is placed under high strain in all directions, by reason of which the quality as well as the quantity of the tone is greatly improved.
What I claim is 1. A stringed musical instrument provided With a resonating-chamber, transversely-arranged threaded braces traversing said chamber, and adjusting-nuts on the outer side of the chamber that engage said braces, substantially as specified.
A stringed musical instrument provided with a resonating-chamber, a slotted bead extending along one edge of said chamber, a pair of transverse diagonal braces, and oblong nuts engaging said braces and fitted within the bead-slots, substantially as specified.
Signed by me at New York city, New York, this 28th day of March, 1902.
