SPECIFICATION forming part of Letters Patent No. 605,942, dated Tune 21, 1898.

Application filed August '7, 1897. Serial No. 647,409. (No model To all whom t may concern: v The bass-bar f, as constructed and applied Be it known that I, MAURICE W'.

The bar f is reduced in depth imroo inediately below the points 3 and 5, as I find that this is necessary in order 'to give the best tone effects.

Bass-bars constructed in the manner above described Will be found to be very effectual in new violins, and also in old instruments where the original bar was intended for low pitch and has to be replaced on account of the higher pitch to which violins are noW tuned.

My invention is also applicable to other instruments of the violin class, such as violoncellos, bass-viols, dsc.

I claiml. In a violin or similar instrument, a bassbar having end portions each consisting of a foot or brace attached to the belly of the instrument and extending from a point adjacent to the end block to a point distant therefrom one-third of the inside length of the bellybetwcen said end block and the bridge, and a middle portion attached to the belly, the bar being separated from the belly between the middle portion and the end portions.

2. In a violin or similar instrument, a bassbar extending Vfor substantially the whole length of the belly of the instrument and attached thereto at all portions of its own length excepting two portions, each of which begins at a point distant from the end block onethird of the inside length of the belly between the end block and the bridge, and ending at a point nearer the bridge.

3. In a violin or similar instrument, an arched belly, in combination with a bass-bar attached along its middle and end portions to the belly and having at each end a recess forming a gap in the line of attachment which extends from a point distant from the end block one-third of the inside length of the belly between the end block and bridge to a point distant from said end block one-hall' of that length, the said recesses extending on either side oi' the straight line joining the ends of the belly.

et. In a violin or similar instrument, a bass bar having reduced portions each distant from the bridge one-third of the inside length of the belly between said bridge and Vthe end block and having two recesses forming gaps in the line of attachment between said reduced portions and the ends of the bar.

In testimony whereof I have signed my name to this specification, in the presence ot' tivo subscribing Witnesses, this 4th day ol.' August, A. D. 1807.
