NELSON B. BAILEY AND IGNAZ A. LUTZ, OF SAN FRANCISCO, CALIFORNIA.

. VIOLIN FRICTION-PEG.

Application filed July 22, 1913.

To all whom it may concern:

Be it known that we, NELSON B. BAILEY and IGNAZ A. LUTZ, a citizen of the United States and a subject of the Emperor of Austria-Hungary, respectively, and residents of the city and county of San Francisco, State of California, have invented a new and useful Improvement in Violin Friction-Pegs, of which the following is a specification. Our invention relates to friction pegs for violins wherein bearing plates secured to the peg-box, are provided with sockets and are frictionally held between rounded shoulders on the peg and on one end of a sleeve thereon, and the objects of our invention are, first, to provide a friction peg that will not slip and relieve the tension of the violin string secured thereto, second, to provide inclined bearing plates that are adapted to lie at various angles to the peg and to engage the slanting Walls of the peg boX, and third, to provide a simple and effective construction that may be secured to the peg-box of any violin without defacing the same or enlarging the holes therein.

F or a full and clear comprehension of our invention reference should be had to the drawings forming a part of the present specification wherein like numerals of reference designate similar parts throughout the said specification and drawings, and in Which Figure 1 is the front elevation of the neck of a violin, disclosing the friction pegs in position and the violin strings secured thereto. Fig. 2 is an enlarged vertical sectional view through the peg-box taken on a line parallel with one of the pegs. Fig. 3 is an enlarged front elevation of one of the bearing plates rotatably mounted upon the square stem. Fig. 4 is a sectional view of one of the bearing plates disclosing the pins which engage the side of the peg-box for the purpose of preventing the plate from turning.

The purpose of our invention is to provide a peg that will not be loosened by the tension of the violin string that is secured to it and yet may be easily turned for the purpose of regulating the tension of or tuning the said string.

The peg-box 1 is provided with the usual apertures for the reception of the pegs. The peg 2 is provided with a rounded shoulder 2' and a square stem 3, having a thread- Specification of Letters Patent.

ed portion 3 at the outer end thereof. A sleeve 4 is also provided with a rounded end 4 and is further provided with a square central bore that is adapted to receive the square stem 3 of the peg 2, the purpose of which will be hereinafter more fully described. Inclined annular bearing plates 5 are provided with the concaved seats 6 and the pins 7 and rotatably mounted on the stem 3. A suitable nut 8 is threaded onto the end 3 of the stem 3 for the purpose of retaining the sleeve 4 thereon. The squared portion of the stem 3 is further provided with a slot 9, and a diametral aperture 10 in the sleeve 4 is adapted to coincide with a portion of the said slot so that the violin string may be inserted through the said aperture and slot. In order to effectively engage the common tapered violin peg the alined apertures in the opposite walls of the peg-box are made one slightly larger than the other.

In providing a violin with the improved friction peg the inclined bearing plates 5 are placed one on each side of the larger aperture. The stem 3 of the peg 2 is inserted through the central opening in each plate 5 and the sleeve 4 is slipped onto the said stem 3 before the end thereof enters the smaller hole in the opposite side of the peg-box 1. In placing the sleeve 4 on the stem 3 the said sleeve is turned so that the hole 10 therein will coincide with a portion of the slot 9 of the said stem 3. The slot 9 in the stem 3 is provided for the purpose of permitting the sleeve 4 to be moved longitudinally upon the said stem 3 without obstructing the passage of the violin string through the hole 10 of the said sleeve 4. After the sleeve 4 is in position the threaded end 3 of the stem 3 is inserted through the smaller hole in the opposite side of the pegbox 1 and the nut 8 is screwed thereon. By screwing the nut 8 against the sleeve 4 I the concaved seats 6 of the bearing plates 5 are engaged between the rounded shoulders 2 and 4 and the pins 7 are pressed into the side of the peg-box 1. The bearing plates 5 are thus secured against rotation and the combination of the rounded shoulders and the concaved seats permits the said plates to be inclined and to adapt themselves to the slanting sides of the walls of the pegbox. The pressure of the rounded shoulders against the bearing plates may be regulated and adjusted by means of the nut 8 until the desired rigidity of the peg is obtained.

It is obvious from the foregoing that we have provided a friction peg for violins that may be efiectively secured against loosening and the consequent reduction in the tension of the violin string secured thereto. We have also provided inclined bearing plates that may be readily adapted to the various slants of peg-boxes.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is- 1. The combination with the peg box of a violin, of a peg having a rounded shoulder and a stem extending beyond the shoulder; a sleeve having a rounded end and slidably mounted upon the stem; inclined bearing plates rotatably mounted upon the stem between the sleeve and the rounded shoulder of the peg, said plates being arranged one on each side of the slanting walls of one side of the peg box; and a nut secured to one end of the stem and adapted to cause the bearing plates to be tightly engaged between the rounded shoulder on the peg and the stem and to engage the slanting walls of the peg box.

2. The combination with the peg box of a violin, of a peg having a rounded shoulder and a stem thereon extending beyond the shoulder; a sleeve having a rounded end thereon and slidably mounted upon the stem; inclined bearing plates having concaved seats therein and rotatably mounted upon the stem, between the sleeve thereon and the rounded shoulder of the peg, the said plates being arranged one on each side of one of the walls of the peg box; and a nut screwed to the end of the stem and adapted to cause the inclined bearing plates to be tightly engaged between the said sleeve and the rounded shoulder of the peg, and to engage the slanting walls of the peg box.

3. The combination, with the peg box of a violin and a tuning peg having a rounded shoulder and a stem thereon extending beyond the shoulder, of a sleeve having a rounded end and slidably mounted upon the said stem; inclined bearing plates having concaved seats therein rotatably mounted upon the stem, one on each side of the peg box and between the sleeve thereon and the rounded shoulder of the peg; and a nut screwed onto the end of the stem and adapted to cause the rounded shoulder and the end of the sleeve to tightly engage the concaved seats of the inclined bearing plates and the said bearing plates to engage the slanting walls of the peg box.

4. The combination, with the. peg box of a violin of a tuning peg having a rounded shoulder and a square stem having a slot therein; a sleeve having an aperture and arounded end thereon slidably mounted upon the said stem, extending beyond the shoulder and the aperture within the sleeve being arranged to coincide with a portion of the slot within the stem; inclined bearing plates having concaved seats therein and rotatably mounted upon the square stem, one on each side of the peg box and between the sleeve thereon and the rounded shoulder of the peg; and a nut screwed onto the end and adapted to cause the rounded shoulder and the end of the sleeve to tightly engage the concaved seats of the inclined bearing plates and the said bearing plates to engage the slanting walls of the peg box.

In witness whereof we have hereunto set our signatures in the presence of two sunscribing witnesses.
