SPECIFICATION forming part of Letters Patent No. 678,516, dated July 16, 1901- Application filed April 13,1901- Serial No. 56,731. (No model.)

To ctZZ whom it may concern:

Be it known that I, GEORGE RIDER, a citizen of the United States, residing at Rensselaer, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Piano-Violins; and I do 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates generally to pianoviolins made like an upright piano, and has for its special object to improve the violinaction.

Figure l of the drawings is a plan view of the frame on which the mechanism is secured; Fig. 2, a side elevation thereof to exhibit the train of mechanism that operates the bow; and Fig. 3, a vertical section on line at w of Fig. 2, showing that part of the frame which carries the bridges and the screw-pins that hold the ends of the strings,

In the drawings, A represents a frame without the encasement, on which the operative mechanism is sustained, while B is the upright part of the frame, on which are made fast the bridges O, and D the screw-pins by which the ends of the strings are adjustably held at the proper degree of tautness. The strings E are made, preferably, of steel, but may be made of any other suitable material.

F is the horizontal key on lever, which is pivoted at f and prevented from lateral displacement by a vertical pin f, which goes through the slot f Near the rear end of the lever is a detachable pin f for a corresponding vertical hole of the lever and holding one end of the cord G. This cord passes over a pulleyf in the front end of the lever, then over a pulley f in an arm H, supported on a cross-bar of the frame, and its lower end is attached to that of a vertical lever I, fulcrumed in an arm I on a cross-bar of the frame.

The upper end of the lever I is connected by a cord K with the reciprocating bow L, which moves in a dovetailed groove or between guides. The rear end of the bow L is provided with a cord M, carrying a weight N. Thus it will be seen that the key mechanism operates the bow in one direction and the weight moves it in the opposite direction. Of course the b0 may be drawn across the wires or strings E with greater or less rapidity and may strike a whole, a fourth, a half, or a sixteenth note.

In the bass there will be but one of the steel wires E for each note; but in the treble there will be two unisons. My musical instrument is in practice not only a maker of melody and a great aid to the singer, but any music may be played upon it.

Having thus described my invention, what I claim as new is- In a piano-violin, the combination with the key-lever, of the cord G working on pulleys f J, the lever I, the cord K, weighted cord M, the bow L and the arranged verticallyat right angles to the bow,

wire string or strings all substantially as shown and described, for

the purpose set forth.

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

GEORGE RIDER.
