Patented June 9,1931
UNITED STATES PATENT OFFICE Application illed larch 11, 1929. Serial No. 346,009. I
This invention relates in general to stringed musical instruments, and more particularly to an instrument of the guitar or banjo type.
An object of the invention is to provide an '5 instrument of the character mentioned in which a single resonator or amplifier is provided, and which will be simple in construction, economical in produces. tonal values not capable of being produced in other stringed instruments of the same type.
Another object is to provide an instrument of small and convenient size having a single metallic resonator of conical form and im- 1 proved means for connecting the resonator with the strings, whereby the vibrations from the strings may be mitted to and amplified by the resonator, than by other means in us A further object is to provide in a stringed musical instrument an improved type of metallic resonator and bridge connecting the resonator with the strings.
Other objects may appear as the description 2 pro resses.
i I ave shown one form of device embodying my invention in the accompanying draw in in which ig. 1 is a top plan view of an instrument.
Fig. 2 is an enlarged fragmentary transverse section of the same on line 2-2 of Fig. 1.
Fig. 3 is a sectional plan'on line 3-3 of ig. 4 is a fragmentary section of the 5 bridge. f
The body B of the instrument is of conventional form, and has a solid bottom 1, an open top 2, and a curved side 3. Any or all of said body members may be formed of wood, composition, or metal, and suitably attached togetherfor providing a hollow resonant body.
The usual neck N is provided longitudinally of the body and has an extension 4 extending longitudinally throughthe interior of the body as shown in Figs. 2 and 3. Said neck carries a plurality of strings S, S etc., which are attached at their outer ends to the usual keys K, K etc., and the inner ends of the strings are attached to a metallic tail piece C overlying the top 2 of the body.. The said top manufacture, and which more efiectively .trans 7 2 has a circular opening 5, or said opening may be of an other suitable form, and it is covered by a etachable plate 6 with a central opening 7 therein. l
An annular head 13 is formed at the outer edge of the resonator, which engages the uper side of the ring 10. Inwardly of the ead, the resonator is bent at 14 so as to providea slightly angular ortion in cross section to permit of the rea y flexing and vibration of the metal.
Centrall of the opening 7 in the cover plate 6, and substantially in the plane of said plate, the upper portion 15 of the resonator is formed with an annular head or ridge 16 therearound and the top of the cone is depressed internally of the head. The plane of the strings S is substantially above the plate 6, and in order to transmit the vibrations from the strings to the resonator I pro vide a circular bridge member A which may have a fiat base portion 17 adapted to rest .upon the head 16 and to be attached thereto by rivets 18. I
The member A. may also be provided with a transverse diametrically disposed rib 19 which may or'may not be notched, for receiving the strings S, S etc. Thus the ribor bar with the strings.
holding the strings in tension, and said bar may be formed integrally with or apart from the member A as shown, for direct contact I have found that by the use of a single resonator and a circular tensioning member, as shown at A, the vibrations from the strings are readily transmitted to the resonator R and the resonator when so connected with the strings serves to substantially amplify the vibration set up in the strings, and the tonal qualities of the instrument are accordingly substantially improved.
i prefer to employ a guard 21 extended transversely of the instrument over the bridge V A. and attached at itsends 22, 22 by suitable means to the cover plate 6. Said cover plate is provided with a plurality of screened openings 23, 23 etc., from which the vibrations from the instrument emanate.
It will be observed that the resonator R is held in position by the tension of the strings and is not at any point secured to the supremoval of the cover plate 6, the members A and R may be readily replaced, removed, or repaired.
In'the construction of an instrument of this character, I have found it important in order to transmit the vibrations from the strings to the resonator and to produce a maximum volume in the instrument, that the member A should be firmly held in contact with the resonator as'at thebead 16 thruout the extent of the annular portion 17. Accordingly, the member A is made of substantial diameter.
Heretofore, instruments of this type have been constructed with a plurality of resonators of substantially smaller size than shown in the drawings relating to this particular device. Also, the bridge which connects the strings with the resonators has been either directly or indirectly connected with the apices of the resonators at single points only. In this device, howeverg by the em loyment of a circular tensioning member which engages the head 16 or the cone for'preterably the full extent of thecircle of contact, the vibrations are more efiectively transmitted to the resonator R than would otherwise be possible, and a satisfactory instrumentmay be provided with a single resonator instead of a plurality of resonators.
It will be observed from the fore oing description' and the consideration of t e drawings of my invention, that I have rovided a simple, compact, economical, and eficient musical instrument with amplified tonal qualities unusual to instruments of this type. I conceive it to be possible to modify the structure shown and described within the scope of the appended claims without departing from the spirit of my invention. What I claim is:
