VIOLIN SOUND-POST.

meagre.

Specification of Letters Patent.

Patented Jan. 5, 1915.

Application filed June 7, 1913. Serial No. 772,259.

To all whom it may concern:

Be it known that I, CARL Srnunn, a subject of the German Emperor, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Violin Sound-Posts, of which the following is a specification. v

The present invention relates to string instruments and has for its object to improve the construction of such instrument with a view of producing a softer, sweeter and more harmonious sound.

To accomplish my object my sound post is made of a single piece of wood or other suitable material and comprises circularly curved parts arranged in alinement and weakened at their junction. The centers of the circular parts are located on the longitudinal central line of said post. At each end the post is provided with two projections arranged one on each side of and equidistantly from the central line, so that the post forms a symmetrical body. The said projections serve to bear against the back and belly of the instrument.

y reason of the weakened part between the two circular parts, the sound post is rendered more or less elastic or vibratory and capable of readily responding to the vibrations created within the instrument. In addition to this each circular part of the sound post is cut out so as to form superposed curved vibrating tongues which will increase the capacity of the sound post to transmit vibrations.

My invention will be more fully understood by reference to the accompanying drawing, in which similar reference characters denote corresponding parts and in which Figure 1 is a longitudinal section through the instrument, the neck of which is broken away; Fig. 2 is a cross section on line 22 of Fig. 1; Fig. 3 is a top plan view of the instrument, the finger board being broken away and the strings omitted for the sake of clearness and Fig. 4 is a detail View of the new sound post.

s an example, I have shown in the drawing a violin, to be limited ment.

although my invention is not to this kind of stringed instru- (2 denotes the back of the violin, I) the front or belly thereof, 0 the bridge and d the strings. The new sound post, which, as ordinarily, is arranged between the back and the belly or top of the instrument, is formed of an integral piece of wood cut out so as to form two circularly curved parts 6, 6 arranged in alinement and forming between themselves a connecting part e which is weakened at the points 6, e. The centers of the two circular parts are located in the longitudinal central line of the sound post so that the latter form a symmetrical body.

Each part of the post is provided with a pair of longitudinally extending projections 8 e e, e which are spaced apart, as at e, e and are arranged at equal distances from the central longitudinal line of the post. The projections e and e to bear against the belly and back of the instrument. The sound post is placed into the instrument so that its projections 6 e engage the belly at points located equidistantly from the bridge (as shown in Figs. 1 and 2).

Each circular portion 6', e is cut out as shown to form a set of superposed curved members or tongues 6 e which when the instrument is used will vibrate thereby increasing the force of the sound.

What I claim and desire to secure by Letters Patent is:

1. A sound post for a violin or like instrument, out of an integral piece to form two parts weakened at their junction and each having apair of longitudinally extending projections arranged equidistantly from the longitudinal central line of the post.

2. A sound post for a violin or like instrument, cut of an integral piece to form two parts weakened at their junction, each part being formed integrally with a set of curved vibrating tongues and with; a pair of longitudinally extending projectionsarranged equidistantly from the longitudinal central line of the post.

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

CARL STEUER. Witnesses E. D. JUNIoR, MAX D. ORDMANN.
