WILLIAM B. TILTON, OF NEW YORK. N. Y.

GUITAR.

Specification of Letters Patent No. 10,380, dated January 3, 1854.

To all whom t may concern Be it known that I, VILLIAM B. TILroN, of the city, county, and State of N ew York, have invented a new and useful Improvement in Guitars; and I .flo hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference bring had to the annexed drawings, forming part of this specification, in which- Figure l is a face view of the instrument, and Fig. 2 is a section on line of Fig. 1, taken perpendicular to the sounding hoard.

Similar letters of reference in the several figures denote the same part of the instrument.

The object of my invention is to stretch the strings of the guitar, so as to give greater vibration to the sounding board, and consequent clearness of tone to the instrument.

It consists in attaching the strings to the foot of the guitar, and carrying them through perforations in permanent pins, at the usual place of fastening, and over a bridge directly in front of said pins to the head of the instrument, thus rendering the strings incapable of lateral movementon the bridge, and giving an additional length of string between the pins and foot; the bridge becoming a fulcrum for increasing the tension of the strings, by the downward action of the pins, thus giving the requisite tension of string between the head and the usual point of attachment, with the advantage gained in tone by the additional string between the pins and foot.

In the drawings a is the sounding board, Z) the head and c the foot of the instrument. Fastened to the foot is the broad hooked plate CZ, having in it the holes c through which the strings f pass while the knots z' on their extremities are drawn against the inner face of the hook as shown in Fig. 2. The strings f pass through the pins 7L fastened in the bridge piece m, and over the bridge n to the head of the instrument where they are drawn tight by the usual arrangement of screws. Instead of the separate pins h there may be used a single piece fastened to the bridge piece m, with holes the proper distance apart to accommodate the strings; or, there may be a straight bar placed the proper distance above the bridge piece m, under which the strings shall be carried before they are passed over the bridge n, the modifications having the effect o1 the perforated pins zy in drawing the strings over the bridge n.

By the above described arrangement, the requisite degree of tension is obtained between the bridge n and the nut t, while the fastening of the strings at the foot and carrying them over the bridge a, precludes the necessity of the bracing usually required under the sounding board, which always has a tendency to injure the tone of the inst-rument.

I am aware that strings have been fastened at the foot of guitars or similar instruments, but in all such cases there is either no bridge, or if one be used, the strings pass loosely over it, and move laterally as each chord is struck, producing a discordant twanging sound, and preventing the benecial elfects which should result from fastening the strings at the foot. This disadvantage I obviate by the use of the perforated pins it, or their equivalent, so as to cause the strings to rise over the bridge n and receive the requisite tension, while the relief thus given to the sound board causes the instrument to have a full, clear, and prolonged tone.

By my invention I give the requisite ten-i sion to the usual length of string, upon which every note is made, and by the additional length of string between the pins and the foot, together with the relief of the sound board from obstruction, produce a vibration which gives a fullness and richness of tone not obtained on any instrumentv of this character.

To enable the instrument` to be made in the lightest manner and still bear the increased tension due to the extension of string I use the device secured by my patent of September 2d 1851, though for the applic-a tion of the present improvement it is not absolutely necessary that the invention covered by that patent should be employed. I do not claim extending the strings from the foot to the head of the instrument-. But That I do claim as my invention and desire to secure by Letters Patent, is

Depressing the strings of guitars slightly below the bridge` by passing them through perforations in the ordinary pins or pegs t or by any means substantially the same, when the strings are fastened at the foot of the instrument, for causing the bridge to not signed my naine before two subscribing witas a fuioruln, 1n producing the tension of nesses.

the strings and so relieving the sound board 7 y T K f M. B. l`ILlOi\. as to give the instrument a richer, fuller 5 und a more complete tone as herein fully set /Tltnesses:

In testimony whereof, I have hereunto ALFRED CHANCELLOR.
