Specification of Letters Patent.

Patented my 11, 1909.

Application filed April 24, 1908. Serial No. 429,0?7.

To all whomit concern:

lie it known that I, OVEREND G. Rose, a citizen of the United States, residing at Camp Meeker,- in the county of Sonora and.

State of California, have invented certain new and useful Improvements in Sound-Ro producfn Apparatus, bf which the following is. a speoi cation.

My invention is an improvement in sound reproducing instruments, and relates particularly'to an attachment for focusing the sounds and for analyzing them so that, for instance in the case of'a reproduction of band music, the volume of .tones will be focused and analyzed the resultant effect being the 1 splitting up of the-sound into the tones of the respective instruments and the placing of S81 tones or sounds in the same relative -.position or at the same relative distance apart that they occupied when they. were payed and the recor originally produced,

. that is to say, the tr'ombones will sound as located farthest back, the tubes and altos in front of them, the iccolos and snare drums still-farther forwarc whilethe sound of the clarinets proceeds from the focusing device I or disk itself.

My invention performs an additional function'to that of focusing and analyzing sounds in that the device augments considerably the strength of the sound and increases its volume.

The invention consists in the features and 1. combination and arrangement of arts hereinafter described and particular y pointed out in the claims. a In theaccom anying-drawingsFigure' 1 isa 'sideview o a horn of a reproducing 1nstrument with my invention associated therewith; 1Fig.-"2 is an endview of the .Fi"g.'

" Fig. 7 is a side view of the mo ified form of sound box shown in Fig. 5; and Fig. 8 is a cross sectional view of the box shown in Fi 7. Tn the drawings 1 indicates a horn of a reproducing instrument. Within the mouth of this horn is arranged my attachment for focusing, analyzing and augmenting the sounds passin from the horn. This evice 2 is suspende in the mouth of the horn by means of links or cords 3 of any suitable material engagin rings or eyelets 4 on the attachment and V Kant attachment with the flared mouth of the orn. i

Besides analyzing and focusing the sound the device also augments it considerablyandso increases it in volume that with an ordinary 22 inch flower lgiven above oneillustration of what I mean horn the human voice will be given off in its natural volume, and the same is true with tin: form first Llb l i Q ml a diaphragm susa, body 11530 F (lei, in said horn and djac-sint the iiiz'ipln'aigiu said body liming :1v
