These stares are grooved stave. as shown 1n Fig. 8.

of the stave, or, indeed, both faces. A strip 10 of thin wood or veneer is now glued into position 111 the groove 9, either on the out.-

side of the stave, on the inside or both sides,

as before mentioned. .Prefer'a-bly as shown 111 Figs. 1 and 8, the groove 9 extendsat an angle to the ax al hne of the staves and the grooves of two adjacent stave's are inclined.

oppositely to each other so that when the strips .10 are in place, the strips will take the I forni of a star-shaped figure when viewed from the small end of the horn. This adds very materially to the ornamental nature of the. horn and, at the same time, the strips 10 prevent the staves from splitting. The

staves are now bent so that the horn will at an angle to each other so as to conform to the. angle of .two adjacent staves. These dowels after being glued in place, prevent the oints from openmg and add greatly to the strength of the joint and to the strength of the horn as a.whol e. I have shown two sets of these dowels, one near the outer seal-- loped edge of the horn and the. other above the slips 10, but I do not wish to be limited to this as I may use more or less of these dowels, as desired. iVhil e prefer to make these dowels fiat with the staves, yet I may allow them to project above the staves by making them thicker than the recesses 12 which they fit. This construction does not change in any way the function of the (low-- els, but adds somewhat to the ornamental effect.- The dowels cooperate with the tongue and. grooves for preventing the joints from opening at the larger end of the horn, while the ferrule S prevents the joints from opening at the smaller ,or month end of the horn. The reinforcing strips 7 and a ferrule at the opposite ends of the staves prevent longitudinal splitting of the fibers at points between the joints of adjacent stavcs. The advantage of this arrangement is that relatively thin slaves maybe employed and yet an extremely strong and durable horn produced. all the tying and reinforcingparts except the ferrule 8, being made of wood so as not to impair the purity of the tone.

The inner end of the strips reduced as.

at 13 to accommodate the ferrule 8. This l protects the wood at the small end of the horn and also serves as the com'iecting means by which the horn is fastened to the elbow splitting is greatest.

, of the usualsoulid-reproducing machine, or

to a reduccrwhich is used where the horn is to be applied to a cylinder-type of talkingmachine.

It will be seen that the construction above described, provides a horn which, being made of wood, has no metallic sound, which softens and sweetcns the tone of the reproducinginstrument, and which is, at the same time, extremely strong and bound together so rigidly as to form a horn practically of one piece of woodwHorns constructed in accordance with my above description, are capable of standinggrcat strain, while they are very much cheaper to construct than the horns now on the market.

Because-of the transverse slips 7 and 10 the individual, staves will not split under changes in temperature, or in service, and because of the dowels 11 the joints between the sta'vcs will not open, nor willthe staves split as they might do under strain if no dowels were used. Since each stave is considerably wider at its outer end than at its inner end, the grain becomes shorter and shorter along the side edges from the narrower to the wider end so that at the wider end the grain is comparatively short, and 'hence the reinforcing strips 7 and 10 are provided at this point where the liability of Along the axis of each stave, the grain extends the full length so that-it is unnecessary to reinforce the stave at the narrower end. Each stave is ofgreatest lcngth alongthe longitudinal axis, since the outer end of the horn is scalloped and the inset reinforcing pieces 7 are disposed in the scallops to strengthen the staves at this point where they are liable to strike should the horn drop on the floor.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be readily apparent to those skilled in the art without further dcscription, and it will be understood that various changes in the size, shape, proportions and minor details of construction may be resorted to without depart ing from the'spirit or sacrificing any of the advantages of this invention. I
