Specification of Letters Patent.

4 Patented. Oct. 2, 1906.

Application filed March 13, 1905- Serial I10. 249.686.

To all whom it may concern: I if Be it known that I, FREDERICK G. PLATTs, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Mandolin Attachments for Guitars; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference be ing had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to a mandolin attachment for guitars, and has for its object to provide a device of the class described which is simple and economical in construction and comprises features of novelty and utility which will presently be fully described, and pointed out in the claims, reference being had to the accompanying drawings, forming part of this specification, in which like reference-numerals refer to like parts throughout the several views, and in which-- Figure 1 is a top plan view of my attachment applied to a guitar. Fig. 2 is a bottom view of my attachment without its clamp. Fig. 3 is a side elevation of the attachment, showing the attaching-clamp. Fig. 4 is a detail View of the clamp. Fig. 5 is a detail view of a modified form of clamp.

Referring more in detail to the parts, 1 is the head, and 2 the neck, of my attachment, which resemble similar parts in an ordinary mandolin. At a point where the neck of the ordinary mandolin contacts with the box neck 2 is provided with a depending shoulder 3, and beyond shoulder 3 is the body 4, which is integral with and forms an extension of neck 2. At the end of body 4 is a tailpiece 5 of any suitable pattern, to which are secured the strings 6, which extend forwardly over the bridge 7 and nut 8 to the keys 9 in the usual manner.

In order to provide the necessary vibration, the body 4 is secured upon a suitable structure, in the illustration shown to be a guitar-box, and the instrument operated in the usual manner. While body 4 may be glued or otherwise secured to the box, I prefer to use a clamp in order that the attachment may remain se arate from, although easily applied to, di erent instruments or structures, and I prefer to use the clamp shown in the drawings, which comprises a rod 10, having a button or head 11 at its upper end adapted to fit within the buttonhole 12 in a slotted plate 13, which is secured to the bottom of body 4 and covers a rooved recess in said body, said rod 10 beingo less diameter than the slot in plate 13 in order that it may have a free longitudinal movement in the slot, while being held from displacement by button 11. At its lower end rod 10 is screw-threaded and carries a thumb-nut 15, and supported by nut 15 is a clamping member 16, which is loosely mounted on rod 10 and is adapted to be raised on said rod by the turning of nut 15 to clamp the body 4 to its To obviate disfiguring a polished box, I preferably surround rod 10 with a jacket 17, of felt or other suitable material, and I further prefer to provide studs 18 on the bottom of body 4, which bear on the top of the box on which the attachment is mounted when the said attachment is clamped to the box instead of being rigidly secured thereto.

My attachment is especially useful for persons arranging music or for those who lay both a mandolin and guitar, as the man olin attachment may be carried with a guitar in its case and is easily attached to and detached from the guitar-box.

While I have described my attachment as relating to a mandolin and in combination with a guitar, I do not wish to so limit myself, as it may be strung for any suitable instrument and be attached to any structure which will furnish the necessary vibration. Neither do I wish to be understood as limiting myself to the other exact details of structure herein shown and described, inasmuch as the same may be varied without departing from the spirit of my invention.

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

1. The combination with a guitar-body of a mandolin attachment comprising an arm and strings mounted thereon independent of the guitar, and a clamp for securing said arm to the guitar-body, for the purpose set forth.

2. The combination with a suitable soundbox, of a mandolin attachment comprising an arm and strings mounted thereon independent of the sounding-box, and a clamp for securing said arm to and removing same from the sounding-box, for the purpose set forth.

3. A device of the class described comprising a suitable neck and a body portion a,

. kee er on said body, and a clamp carried by ola-mp rod adapted for longitudinal movesai keeper, for the purpose set forth.

4. The combination with .a guitar-body, of I a mandolin attachment, com rising an'arm" and strings mounted thereon lndependent of the guitar, a c'lamp-rod carried by said arm 1' having screws-threads at its loose end, .a

clamping member loosely mounted on said rod, and a thumb-nut threaded on :said mod for liaising and lowering said cl-ampingmem- 5 ber substantially :as set fonth.

5,. Theicombination with aguitar bod-y, 10f

Y-a mandolin attachment oompnlising am arm 1 and strings mounted thereon independent of 15 the guitar, a slotted plate on said arm, a

mentin said plate, .andhaving a button on its upper end for supporting it in said plate, and a clam ing member on the lower end of said :0

rod s11 stantially as and for the purpose set tenth.

In testimonywhereof I aflix my signature in presence of two witnesses.
