MUSICAL INSTRUMENT STRING Filed July 27, 1936 INVENTOR. fay/770M c5. oa/dcf/f ATTORNEYS Patented Mar. 22, 1938 UNITED STATES PATENT OFFICE MUSICAL INSTRUMENT STRING Mich.

Application July 27,

8 Claims.

Musical instrument strings of the wound type are commonly made with a gut core or tension member, and this is subject to substantial change under varying weather conditions, stretching materially in damp atmospheres and tightening or contracting in dry atmospheres, which renders it difficult to keep the strings in tune, and this also results in changing of the tone quality of the strings.

The main object of my invention is to provide a musical instrument string of the wound type which is not materially affected by atmospheric conditions and the tension element is not subject to material stretching and contracting and at the same time has a very satisfactory tone quality.

A further object is to produce a musical instrument string having these advantages which may be produced economically.

Objects relating to details of construction will appear from the description to follow. The invention is defined in the claims. A structure embodying the features of my invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a side view, conventionalized, of a musical instrument string embodying the features of my invention.

Fig. 2 is an enlarged transverse section taken on line 2-2 of Figs. 1 and 3, the diameters of the elements being greatly exaggerated for convenience in illustration.

Fig. 3 is a fragmentary view, partly in longitudinal section, taken on line 33 of Fig. 2.

Fig. 4: is a fragmentary perspective View.

3 Referring to the drawing, my improved mu sical instrument string, designated generally by the numeral l, comprises a plurality of strands 2 of fine wire disposed in parallel relation and extending from end to end of the string. These 40 strands are not twisted, and while in Fig. 2 I

have illustrated them as being accurately positioned relative to each other, it will be understood that in practice it is not necessary to have the wires grouped in this exact manner but they are merely grouped side by side and in as compact bundles as may be conveniently done. These wires constitute the tension element of the string and around them I arrange strands of fibrous material 3, preferably of silk, or other fine fiber may be used. These strands are not twisted together but are arranged longitudinally of the string and of the tension element, the arrangement being such as to provide a fibrous covering of approximately uniform thickness around the wire strands.

1936, Serial No. 92,767

Upon these strands of fiber I wind a wire covering 4, this being spirally wound and under such tension as to compressibly embrace the fibrous strands, holding the fibrous strands and the longitudinal strands 2 in their assembled relation. To provide a knot or enlargement 5 for engagement with the tail piece, a double winding of the covering Wire is provided, and I preferably provide the string with a reduced portion 6 for engagement with the tuning pegs.

This musical instrument string has highly desirable tone quality and may be manufactured with great uniformity. It is not subject to material expansion and contraction, which obviates many of the difficulties experienced with wound strings having gut cores. Owing to the fact that the strands are parallel there is no material extension when placed under tuning stress. The string may be economically produced and it is very durable.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A musical instrument string comprising a plurality of longitudinally parallel strands of straight, uncoiled, fine wire, longitudinally disposed strands of silk arranged about said strands of wire to provide a substantial casing therefor, and a wire covering spirally wound upon said strands of silk and compressively embracing the same.

2. A musical instrument string consisting of a plurality of strands of straight, uncoiled, fine wire disposed in longitudinally parallel relation, longitudinal strands of fibrous material disposed about said strands of wire in parallel relation thereto and constituting a fibrous covering therefor, and a winding strand of wire helically wound upon said fibrous strands and compressively embracing the same, said strands of wire constituting the tension member of the string.

3. A musical instrument string comprising a plurality of parallel strands of straight, uncoiled, wire providing a tension member for the string, longitudinally disposed strands of fibrous material arranged about said strands of wire, and a wire covering spirally wound upon said strands of fiber.

i. A musical instrument string consisting of a plurality of strands of straight, uncoiled, wire disposed in parallel relation, strands of fibrous material disposed about said strands of wire and constituting a fibrous covering therefor, and a Winding strand of wire helically wound upon said fibrous strands and compressively embracing the 7. In a musical instrument string, a plurality of strands of fine wire disposed in longitudinally parallel relation providing a tension member for the string, strands of fibrous material parallel to the tension member and constituting a cover therefor, and a further covering member enclosing said strands.

8. In a musical instrument string, a plurality of strands of fine Wire disposed in longitudinally parallel relation providing a tension member for the string, a fibrous cover for said member, and a further covering member enclosing said cover.
