STRINGED INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 572,906, dated December 8, 1896.

Application filed April 9, 1896. Serial No. 586,773. (No model.)

To all whom it may concern:

Be it known that I, EDGAR MONICHOL, of WVest Jonesport, county of Vashington, State of Maine, have invented an Improvement in Stringed Instruments, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to violins and other instruments of the Viol family, and has for its object to improve the construction of the instrument in several particulars, whereby the quality and durability of the tone is enhanced; and the invention consists in many details of construction to be hereinafter set forth and claimed.

Figure 1 shows a rear or inside view of the back of a violin graduated in accordance with this invention; Fig. 2, a cross-section of the back shown in Fig. 1, taken on the dotted line 00 00; Fig. 3, a longitudinal sectional detail of the back, taken on the dotted line y Fig. 4, a front View of a violin embodying this invention Fig. 5, a longitudinal section of the back of the instrument; Fig. 6, a crosssection of the violin shown in Fig. 4, taken on the dotted line 2 .2; Fig. 7, a detail showing a portion of one of the Ds and the corner-block, and Fig. 8 a detail showing the lining at the lower end of the D; Fig. 9, a detail showing the marginal strips at the edge of the instrument.

The back a of the instrument is graduated in the following novel manner: It has a thickened portion a, at the waist extending transversely across the lower part thereof and embracing or including the sound-post contact. This thickened waist portion a is gradually reduced in thickness from the center or thereabout toward the edges or sides of the back. This thickened waist portion a is also gradually reduced in thickness toward the upper lobe. The upper lobe may be graduated in any usual manner, but is herein represented as gradually reduced in thickness from a cen tral thickened area 6610, more or less elliptical in shape, toward the edges, as well as toward the waist. As a result it will be observed that a thin portion is produced between the upper part of the waist and the upper lobe, t'. 6., between the parts a and a The lower lobe has a central thickened portion a of suit- -the thickened waist a.

able size and area, and as the lobe is itself more or less elliptical this thickened part may, if desired, be also made elliptical. It may be made, however, to cover but little area. The central thickened area a of the lower lobe is gradually reduced in thickness toward the edges of the back and also toward The lower part of the thickened waist a is abruptly reduced in thickness, as, for instance, by forming an abrupt shoulder thereat, as shown at (W, Fig. 3, although it may be gradually reduced in thickness, if desired. As a result it will be observed that a thin portion is produced between the lower part of the waist a and the central thickened portion or area a of the lower lobe, 'L. 6., between the portions a and (L The thin portion thus produced weakens the back a between the waist and the lower lobe. It is desirable that this part of the back shall be very thin, and to give the strength required and afford the proper resistance a narrow longitudinal projection 0 extends from the thickened waist portion a toward and to the thickened portion or area a at the center of the lower lobe. This projection a appears as a rib, and may, and preferably will, gradually taper off toward the lower end or lose itself in the central thickened area a ofv the lower lobe, its upper end lying substantially flush with the thickened waist a. A similar rib or projection a extends from the thickened waist a upward to the central thickened portion a of the upper lobe, the lower end of said rib lying substantially flush with the portion a, and the upper end terminating substantially flush with the portion a Two other like longitudinal projections or ribs to are formed on the inside of the back a in parallelism with the aforesaid projection or rib (L or substantially so, they being arranged one at each side of the thin formation between the thickened waist a and central thickened area a and practically in continuation of the long central portion of the Ds. These projections extend to and lose themselves in the thickened area a of the lower lobe.

The projections a a a are preferably formed by working out the back, but of course they may be made as independent pieces attached to the back, and so also the transversely-thickened waist portion a may be made as an independent piece suitably affixed, or it may be worked out.

Usually the back of the instrument is worked out or graduated in such a manner that thin edges are formed all around it, but herein I have formed at its upper and lower ends a raised portion extending from the outer edge inward toward the centers of the lobes, as at a a. Extending inward from said raised portions a a toward the centers of the upper and lower lobes are projections or ribs (0 (L13, which terminate at or near the central thickened areas of said lobes, vanishing at such point.

The back a is made or formed exteriorly as a saddle-back, that is to say, it is depressed at the waist in longitudinal lines extending from lobe to lobe, as represented at a (see Fig. 5,) and is also depressed transversely in opposite ways from a single central longitudinal line a extending from lobe to lobe. By thus forming the back a it will be seen that the sounding-post contact will be located within the depression at one side of said line a The top and back of the instrument are each usually made of a single piece of wood supported upon the rim, and consequently the grain of the wood of said parts runs lengthwise from nut to tailpiece. In such'case at the sides of the instrument the grain runs along with the rim and the vibrations are not readily transmitted.

I have herein cut away the top or back or both of them along such portions of the instrument as the grain runs lengthwise the rim, and have secured to such cut-away portion marginal strips 1), (see Fig. 9,) made of wood with the grain running toward the edges of the instrument. Such marginal strips may be located at each side of the upper and lower lobes with the production of good results. The marginal strips Z) are formed with arabbeted edge to receive the back a or top. As before stated, these marginal strips 1) will be provided along the sides of both the upper and lower lobes of both the top and back of the instrument, but of course they may be provided along only such portions or parts as may be desired.

The rim 6 of the instrument usually has the grain of its lining-strip running lengthwise, and herein I have provided said rim with a lining-strip e, the grain of which runs vertically or from top to bottom. (See Fig. 8.) Such a lining-strip 6 may be applied to a reduced portion only of the rim, and in practice I find that good results are obtained by employing such a lining-strip along the lower ends or curvatures of the Ds.

The corner-blocks dare made tapering from end to end, from back to top of the instrument, the end of largest area being located at the back of the instrument.

In the top of the instrument, to secure greater strength in the lower lobe and decreased resistance at the corners, I have placed the lower circular terminations c of the f-holes well into the corners and define their position as equidistant or thcreabout between the adjacent or marginal part of the side of the instrument and the adjacent marginal portion of the lower curvature of the Ds.

It is obvious that all of these many features of novelty need not be embodied in the instrument, although I find in practice that an instrument having all of these features does produce a very much better tone than the ordinary or well-known form.
