l the hollow sound box of the instrument from a socket 19 in its inner the tension of the strings, and thus permitting the sound box to more scientifically and accurately execute its vibratory functions, thus bringing out and properly accenting the correct tonal qualitiesof the instrument. Further objects will be disclosed inf the course of the following specification and are illustrated in the accompanying drawing, in which: y

Fig. l isI a vertical sectional view` through the center oftl a violin `embodying my invention.

F ig. 2 is an enlarged detail view ofthe heel plate 18, or as seen from the lett in ig. 1. i Referring to the drawing by reference characters 3 designates a violin body having a neck piece 5, a linger board 6, strings a ybridge 8, and a tail piece 9, all cit common and well known construction. 1n the end a of the instrument l drill two holes 10 and 11,\in the latter ot which is inserted a tubular brace 12 which extends through the length of the body. A extends through the brace l2, and is secured with its head 14 in a hole in the neckfpiece 5y of the instrument. A` plug 15 may be inserted in this hole sothat it will not benoticeable.

An angular brace 16 is inserted in the hole l0 and engages a notch 17 in the brace 16, with its inner end. A heel plate 18 has side adapted to engage the outer end of the 'brace 16, and is provided with two notches 2O in which may be secured the flexible loop 2l of the tail piece 9, to the latter of which is secured the strings `7. The lower end of the .heel plate 18 is adjustably secured to the rod 13 by any suitable means, a convenient con` struction being shown, and consisting of :i set screw 22 which is rotatably mounted in the plate but threads onto the krod 13 so Specification of Letters Patent.

that whenfit is turned the lower end of the heel plate will be adjusted closer to or fartheraway from the instrument, asdesired. l't'will thusy be seen that with the various parts constructed and properly adjustedv as above described, the strain caused by the tautness oi4l the strings 7 will be taken up entirely by the parts'9, 21, 18, 16, l2, 13, 22, 14 and 5, leaving the sound box or body of the instrument free to vibrate as it properly should do.

it is of course understood that the invention as here disclosed is purely illustrative.

and is not to be taken in a limiting sense. Suitable modifications lmay be made, provided, however, that suoli modiiications come within the spirit and scope of the appended claims. Having' now. therefore fully shown and described my invention whatl claim to be new and desire to protect by United States Letters Patent is:

1.The combination with a stringed instrument having a hollow sound box and a neck piece secured thereon, of a heel plate at the butt end `of the instrument, strings positioned over the face of the instrument and means ior securing' them to the heel plate, a hollow brace extending longitudinally within the sound box, a rod within the brace, said rod being secured at one end in the neck piece and having its other end terminating in the heel plate,fan angular brace bracing the heel plate against the first mentioned brace whereby the plate will be spaced Afrom the sound box.

2. The combination with a stringed instruinent having a p a neckpiece secured thereon, of a heel plate at the `butt end of the instrument, strings positioned over the face of the instrument and ineansy for securing them to the heel plate, a hollowbrace extending longitudinally within the sound box, a rod within the brace, said rod being secured at one end in the neck piece and having its/other end hollow" sound box and plate, a hell brace hai-ring a no'teh in its rear part extending longitudinally within the sound box, a rod Within the brace, said rod being secured at one endl in the neck piece and at its other end in the heel plate, an angular brace exteiulinethrough the butt end of the sound hoi; sain angular brace and said engaging` the heel plate at one end brace noteh with the other end.

Ll. The combination with a stringed instrument having a hollow soun d looX and a neck piece secured thereonj of a heel plate at the butt end of the instrument., strings positioned over the face of the instrument and means for anchoring the strings to the heel plate Consisting oit a tail piece hav ing a loop adapted 'to be secured in a pair oit angular notches in the heel plate; a hollow brace extending` longitudinally Within the sound box, a rod Within the brace, said rod being secured at one end in the neck piece and having` its other end terminating in the heel plate, and an angular brace bracing the heel plate against the first inentioned brace, as and for the purpose set forth.

ln testimony whereof, I afiix my signature.
