. vide a string peg which can be readily turned in its bearing in the peg-head of the instrument and which when released will remain in the adjusted position.

It has always been a source of annoyance to persons using stringed instruments to have the pegs slip in their bearings and throw the instrument entirely out of tune, and to overcome this annoyance and defect is one of the principal objects of our inven- The objects and advantages hereinbefore referred to may be attained by means of the device illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of the peghead of a violin and showing our improved pegs connected thereto, Fig. 2 is a sectional view taken partially through one of the keys and through the peg-head, Fig. 3 is a detail perspective view illustrating the lever and press button detached from the peg, Fig. 4 is a transverse sectional view of the bushing for the peg, Fig. 5 is a diametrical section of the same.

Referring to the drawing the numeral 1 designates the peg-head of a violin and 2 designates a metal bushing inserted in one of the bearings for the peg. This bushing as shown in Fig. 4 consists of a metal ring 2 having projecting ribs 3 upon the outer surface thereof to prevent the turning of the bushing in the bearing hole in the peg-head. The interior surface of the bushing is plain and smooth at the opposite ends thereof, as indicated at 4, while in the center a series of notches and intermediate teeth or ribs 5 are provided. The ribs 5 are formed in a recess in the bushing so that the peg may have a smooth bearing on the portions 4 at the ends of the metal bushing.

The peg is provided with a smooth shank 6 having a hole 7 therein for the string 8 of the instrument, said shank 6 having a smooth bearing at 8 for one end thereof. The opposite end of the peg is provided with a recess 9, and pivoted at 10 in said recess is a lever 11 having a curved portion 12 terminated in a finger 13, the end 14 of which is sharpened or of wedge-like contour to engage the notches between the teeth 5. The outer end of the lever 11 is provided with a press button 15 which is secured to the lever by means of a projection 16 extending through the button 15. The button 15 is disposed in a circular recess 17 of the peg-head and seated in the recess 17 is a spring 18 which is connected at one end with the lever 11, said spring being seated in the notch 19 in the lever immediately under the button 15.

From the foregoing it will be obvious that as the peg is grasped between the thumb and finger the button 15 is pressed open to operate the lever 11 and to disengage the finger 18 from the notches between the teeth 5, the peg then turning in the bushing 2 and the bearing at the opposite end of the shank 6. When the thumb and finger are released from the `head of the peg it will remain in the adjusted position and will not slip by the strain of the spring thereon. The peg is provided with a shoulder 2O which serves to limit the inward movement of the peg in the bushing.

Our peg can be used for various kinds of stringed instruments and will serve to prevent the slipping of a peg in its bearings and will at the same time permit the peg to be readily adjusted without binding in the bearings.
