SOUND REPRODUCING BELL.
APPLICATION FILED AUG. 2, 1907.

Specification of Letters Patent Patented Nov. s, 1908.
Application filed August 2, 1907. Serial No. 888,806.
T 0 all whom it may concern:
Be it known that 1, CHARLES G. CONN, a citizen of the United States, residing at Elk: hart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Sound Reproducing Bells, of which the following is a. specification.
While I shall describe my invention more particularly with reference to sound reproducing machines, commonly known as gram phones and honogrephs, at the some time it will be un erstood that my invention is equally applicable to megaphones and other sound conveying;horns and the like. For purposes of brevity, I shall in this s ieciiicalion and the claims following use the term bell to include the horns usually employed on sound reproducing Inuchiues and, megaphones.
As is will known, there are three tones, namely, the upper, the middle and lower tones of the musical scale, and heretofore the varied vibrutions of the dill'ereut tones were all taken up in u single clunnbered hell, with the result that the vibrations of the higher tones are practically lost in a elunnber of a. size to properly reproduce the lower tone.
The object of my invention is to produce a bell having in. series of sounil,\vnve chambers, whereby the full richness of the sound waves from the three tones is preserved and asses from the hell to the atmosphere; em with this and minor objects in view, my invention consists of tile parts end combination of parts hereinafter more specifically set forth.
In the drawing, Figure 1 is a, front elevation of the. bell embodying my invention. Fig. 2 is a sectional view on the line II-II, Fig. l.
'lhe bell embodying my invention consisis ol' the outer horn 1, the inner born 2, which is secured to the outer horn at its inner end by menus ol' lnstcnings 3; 4 is an intermediate horudispnsed within the outer born I mid between it and the inuer llllru 2. 'lbis iuteruudiotc horn is secured to the inner horn at its forward end by means of the loops 5, while at its inner end, it is secured to the inner born 2 by means ol' suitable fastenings 6. As will be seen from the drawin the inner horn'2 extends beyond the Inout of the horn 1, but does not extend to the rein end of the horn 1. The horn 4 is shown at its front end ilush with the mouth of the born 1, while its rear end terminates short of the FEM end of the horn2. These horns, as will be seen, are nested and at their rear ends terminate short of each other. When this bell is attached to a. sound reproducingmztchine or is embodied in a mega hone, the lower tones puss out through tie horn I, while the middle tones pass through the born 4, and the higher tones through the horn 2.
My theory is that where large bells are used for sound reproduction by the ordina process, the sound wove chamber in the b l is too large for the feeble vibrations which reproduce the higher tones, and if asmall sized bell is used, the sound wave chamber is too small for properly reproducing the lower tones. there is a. sound wave chamber for the reproduction of the upper, middle and lower tones of the musical scale, and all can be reroduced with equal volume and elesrness.
he hell can be made of any materiel suitable for that purpose, or of on y size fouruLdesireble by the manufacturer.
Claims.
1. A bell for convoyingsound, comprising coexislly nested horns, terminating at different distances from the rear end of the hell.
2. ,A. bell for conveying sound, comprising three eonxielly nested horns for the upper middle and lower tones of the musical scale,
the largest of said horns eJgtcnding furthest to the rear, and the smallest extending furthest to the front of the bell.
