TUNING DEVICE FOR MUSICAL STRINGED INSTRUMENTS.

SPECIFICATION forming part of Letters Patent No. 609,715, dated August 23, 1898. Application filed DecemberlS, 1897. Serial No. 662,49 7. (No model.) Patentedin Austria S t b 1'7 1897, No. 3,427.

To (tZZ whom it may concern:

Be it known that I, EMIL WETTENGEL, a subject of the King of Saxony, German Emperor, residing at Markneukirehen,Germ any,

I have invented certain new and useful Iniprovements in Timing Devices for Musical String Instruments, (for which I have obtained a patent in Austria, No. 3,427, dated September 17, 1897 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

To tighten the strings of many string in- 1 struments, pegs are generally employed, carrying on the outside a worm-wheel, which is operated by a worm. This mechanism is customary, especially for instruments of larger size; but in stringing an instrument and tak ing up the slack of the string when first brought in place much time is lost, because in view of the gear of the worm-wheel the peg revolves very slowly. The present invention has for its object to obviate this inconvenience, and the mechanism described hereinafter enables the musician to quickly turn the peg at first and then to bring, it into engagement with the worm-wheel for fine tuning.

In the accompanying drawings the device is shown in Fig. 1 in front elevation. Fig. 2 is a perspective view of the device, and Fig. 3 shows the'peg and knob in detail.

The pegs A are lodged in the head of the instrument in the usual manner; but they are placed in their bearings in such a way that they permit of a small longitudinal displacement. They pass through suitable holes in the head, of wood or other material, and

r they pass at the same time through a bush or sleeve B, revolubly secured to the head and having at the outer circumference the teeth of a worm-wheel into which a worm B engages, having its shaft at right angles to the corresponding peg A. Thus this worm-wheel is securely but revolubly attached to the head of the instrument. The pegs A carry at their outer end a knob A, screwed thereto or secured in any other suitable way. Said knobs A are provided with a projecting tooth to, which, by pushing the peg longitudinally inside, can be thrown into one or any of the notches a which are cut into the projecting hub l) of the worm-wheel B.

It is evident that the pegs when in the outward position (see middle peg, right-hand side, Fig. I, and upper peg, Fig. 2) can be turned freely by using the head or knob A. Thus the slack of the string can be fully taken up and the string can even be brought up quickly to its final pitch, and then the musician pushes the peg longitudinally inside, so that the pin a rests in a corresponding notch a, thereby coupling the two parts together.

In making use now of the ordinary device t. e. ,the thumb-piece of the worm B the worm B will turn slowly and will compel the peg to follow in the revolution, so that it is easy to tune the instrument finely.

Having thus described my invention, I claim- 1. In string instruments, a peg adapted to be moved longitudinally, passing loosely through the Worm-wheel of the ordinary tuning device and having an outer head with a projecting tooth adapted to enter into a notch in the worm-wheel, substantially as described and for the purpose set forth.

2. In string instruments, pegs longitudinally movable in the head of the instrument, worm-wheels revolubly secured to a plate and adapted to be operated by worms secured on the head of the instrument, said worm-wheels having hubs each provided with a notch adapted to receive a tooth or projection of the knob or thumb-piece, said knob or thumb piece being located on the outer end of said pegs, whereby when the strings have been tightened the pegs can be pushed longitudinally inward and locked, substantially as described and for the purpose set forth.

In testimony whereof I ailix my signature in presence of two witnesses.

EMIL WETTENGEL.
