A. EILERT FRAME FOR STRINGED MUSICAL INSTRUMENTS Filed Oct. 12, 1925 Patented Feb. 2 2, 1927.

ADOLF EILERT, OF BRUNSWICK, GERMANY.

FRAME FOR STRINGED MUSICAL INSTRUMENTS.

Application filed October 12, 1925, Serial No. 62,151, and in Germany April 25, 1925.

My invention relates to improvements in frames for stringed musical instruments, and

a the object of the improvements is to provide a frame in which the strength of the tuning plank as against bending stresses is large as compared to its cross-section, and in I which the number of the supporting means for the said tuning plank may be reduced,

' the said tuning plank being supported in some cases exclusively at its ends. Another object Of'tllG'lIIlPIOVBlUBDtS is to provide a frame the wooden tunin plank of which is V a l proof as agalnst atmospheric lnfiuences,

' which is important forexample when ship- "left in Fig. 1,

ping the instrument such as a piano to tropic-countries. With these ob ects in view through which'the tuning pins are screwed into the .wooden part of the plank.

For the purpose of explaining the invention an example en'ibodying the. same has been shown in the accompanying drawing, in which the same reference characters have been used in all the vlews to indicate corre- Y spending parts. In said drawing,

Fig. 1, is an elevation showing the frame and the sounding board carried thereby,

I Fig. 2, IS an end view looking from the Fig. 3, is a sectional view taken on the f 1ine33 of Fig. 1, and

Fig. 1, is a perspective view showing one of the corners of the, frame.

In the example shown in the drawing the frameconsists of side members a and 7) and bracesc and cl connecting the said side 1119m i I the strings thereto, the side members a and I 'bers and provided with pins for attaching portions it through which the tuning pins i are screwed into the wood part 7. Below the said cut-out portions bridges made from brass or another suitable metal are ixed to the jacket g. The sounding board m, which in the example shown in the figures is in the form of a box, is secured to the frame in any known or preferred way.

In most cases the strength of my improved tuning plank is sufficient to take up the tension of the strings n when being freely supported exclusively at its ends. But in some cases I provide a bracing member 0 fixed with one end to the jacket 9 and with its opposite end to the side member a.

I claim:

1. A frame for stringed musical instruments comprising a body having a bottom member and two side members, and means securing the upper ends of said side members to each other to complete said frame, said means comprising a wooden tuning plank, and a metal jacket enclosing said tuning plank. I

2. A frame as set forth in claim 1, wherein the metal jacket enclosing said tuning plank is cut away to expose the tuning plank at points where tuning pins are to be secured thereto. 7

In testimony whereof, I aflix my signature.
