BANJO.

SPECIFICATION forming part of Letters Patent No. 517,913, dated April 10, 1894.

Applicationfiled January 29, 1894. Serial No. 498,289. (No model.)

To all whom it may concern:

Be it known that 1, JOHN F. BARROWS, a citizen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Banjos; 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 being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention is a banjo, and consists in the combination, arrangement and adjustability of the parts hereinafter shown, described and claimed.

Figure I, is a perspective of a banjo containing my invention. Fig. II, is a side perspective of the tail piece. Fig. III, is a side perspective of the neck tightening device. Fig. IV, is a side elevation of the same. Fig. V, is a perspective of the adjusting device for the stem of the neck. Fig. VI, is a perspective of the end of the stem.

A, is the banjo body, B, the drumhead or parchment, and D the bridge. I

O, is the neck having a stem 0 extending through an orifice in the body A, into and across the body, and engaging an end adj usting device I, secured to the inside of the body. Upon the end of the stem 0', I secure a corrugated end plate J, having integral therewith acentral lug J". The adjusting device Lheretofore mentioned, consists of a piece of metal. secured to the body perpendicular to its plane, and having its exposed surface corrugated, I, and adapted toengage and mesh into the corrugations J on the'plate J when placed in.contaot. This piece I, has a longitudinal groove I transversely to the corrugationsl. The lug J" passes into this groove 1",when the piecesI and J are in engagement, and travels up and down in it as the end piece J is moved, and prevents any lateral movement of the stem 0. The stem 0 is also provided with a perpendicular slot 0', rectangular in form, located at the head of the stem at the point where it passes through the body A, the greater part of the slot being within the body, and large enough to receive the fastening device shown in Figs. III, and IV. This fastening device is one of the special features of my invention. Heretofore it has been common to use a wedge, or a plate secured by screws to the body and stem, both being unsatisfactory;-the wedge because of the liability to become loose in use and by the operation of the temperature uponthe material; theplate, because it is impossible to satisfactorily tighten or secure the body to the neck with that degree of tension required. This device consists of the plate L adapted to pass through the slot and extend from each side thereof, and has a right angle arm L, upon one end thereof.

5, is a piece of metal movably secured and depending from the arm L and at the proper distance from the plate L. The outer surface of the piece 5, is straight and engages the straight end of the slot 0', the inner surface is beveled, being larger at the base than at the end.

6, is a piece of metal held between the plate L, and the piece 5, by the screw rod 7, passing through a hole in the arm L. This piece 6,has a straight surface engaging the straightsurface of the plate L, and a beveled surface engaging the beveled surface of the piece 5. The screw rod 7, screws into a screw-threaded hole in the part 6, and as the screw is turned to the right the part 6 is drawn between the plate Land the piece 5, which operation will, it is obvious, move the piece 5 farther from the plate L.

8, is a hook depending from the arm L, engaging the piece 5, and along this hook the piece 5 travels as it is forced away from the plate L by the part 6. It will therefore be seen that if this device is placed within the rectangular slot 0" with the plate L resting against the inside of the body A, and the piece 5 against the end of the slot, turning the screw 7 in the proper direction will draw the part 6 between them and thereby tighten and firmly secure the body A, upon the neck 0. Other means of forming and securing the movable piece 5 may be devised, as will be obvious, without departing from the principle of the tightening device I have described. I have also shown a new and peculiarly adaptable, and adjustable, tail piece. This tail piece 1 form in two parts, E, and F. The

part F, answers the purpose of the old form of tail piece. The strings S, are secured to it by tying them through the holes 2 in the ridge 2. It may then be caught upon the rim R, by the shoulders 4, of its head 3. Tightening the strings would now show the old style of tail piece. In front of the ridge 2 and at each end thereof extend arms 1,for the proper distance, and carry the rod 1 under which I pass the strings. The purpose of this will hereinafter appear.

Banjo players observe that lowering or raising the strings S, to or from the drum head back of the bridge materially changes thetone of the instrument. My tail piece is designed to furnishmeans for this adjustment, and the part F, described, I have formed with that purpose in view, and for that reason I catch it over the rim inthe old style instead of securing it in the way now common, viz: by having a shank passing down the body A, and through an eye or log, and held by a nut. The other part, E, of the tail piece consists of a hook shaped piece E, and E, E, being the hook artistically designed, with a shank or stem E. This piece E, and E fits within the part F, the stem E passing through the head 3, without engaging it, down the side of frame A, but free from it, through an eye in the nut 11, that screws upon the shank II of the plate I. E is screw threaded to receive a nut, N, which screws upon it' up to the eye in H, thereby tightenin 'it.

Ids previously stated, the part E fits within the parts of F, except a rod E" carried upon the end of E which engages and rests upon F, just back of the ridge 2. This is the only support the piece E, has, and it is obvious that as the nut N, is turned upon the shank E, it will draw upon the part F at the point where the rod E" engages it; and F being fulcrumed at its head 3, on the rim R, its front end 1 will be drawn down toward the drum head B, thus lowering the string S. It is obvious that the head F will be held firmly to the rim R, by the part E engaging F, as described. The strain of the tension of the strings being taken from the adjustment, it is obvious that the adjustment can be made much easier and quicker than otherwise.

I do not wish to confine myself to any particular form of the mechanism shown, and therefore any change may be made that ordinary mechanical skill would suggest without departing from the principle of my invention.

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

l.
