To all whom it may concern.'

Be it known that I, Connu. W. JonNsoN, a citizen of the United States, and resident of the city of New York borough of Manhattan county .of New York, and State cf New Yorhhave invented a new and Improved Sound Clarier, of which the followi is a full, clear, and exact description.

y invention relates to5 a sound clarifier and aims to provide certain new and ful improvements in connection with a device of this character and more particularly over my prior Patent No, 1,240, 50 of September 11, 1917, as well as my previous a plication N o. 367,412 of March 20, 1920, it ing further an ob'ect of this invention to rovideb: more desirable for use in certain app ications than the structure described in my conding application Serial No. 568,587, tiled une 15, 1922, entitled Sound clarifier.

More particularly with respect to the oonstruction noted in m fprevious application- Serial No. 367 412 file March 20, 1920, it has been found that certain objections have arisen in connection with the mounting of the auxiliary horns, as well as the propagation of the sound waves therethrough.

Thus it is an object of the present inven. tion to provide a sound` clarifier which is particularly intended for use in connection with talking machines although not necesand means of which a device o this nature may be constructed in an extremely simple and economical maner.

A further object of the present invention is that of providing a sound clarifier in p ed thereto, it being further noted that I prey which an auxiliary horns or tubes will be supports in a manner more desirable, and in which however, the sound waves willjlie introduced into these members to achieve a better result.

With these and further objects in mind the resent invention has reference to a soun clarifier including an amplifying chamber within which means is provide permitting of the accomplishment of the results setforth. I

In the attached sheet of drawings 1t will be seen that a practical embodiment ot my invention has been shown in these drawin s.

Figure 1 is a sectional side view of a ta king machine`-d binet and` showing my improved type/ clarifier in association therewith, and

sarily limited to this particular ap lieation,

inset in both de Wal Figure 2 is a sectional plan view taken along the line 2-2 and in the direction of thearrows indicated in Figure 1.

In these views it will be noted that the reference numeral 5 indicates the lid of the cabinet 6, which latter houses the turn table 7, and reproducer 8 co-operating therewith, this latter element being supported by the tone arm 9 which is in turn connected to mzimproved ty of clarifier.

eferrin to t e ter it will noted that the'same embraces a neck I0 or sound conveyor 10, and an ampllfying chamber 11, these'members being ormed by two separate elements, if it is so desired. Also contrary to conventional construction it will be seen that I prefer graduate the walls of the sound conveyor to a relatively glreat 4thickness adjacent the outer end of t is member as has been .indicated at 12, and these thickened walls 'are preferably provided at opposite points in the tone conveyor, and each present dual passages 13 extending direction as the bore o thev passage of both the conveyor and amplifyin member.

Each of the passages em races a tlarin mouth 14 so that a rtion of the soun waves will be diverte into each passa e in their outward course through the soun conveyor, and these diverted sound waves are conducted in a manner hereinafter described, through tubee 15 into horns or de- !lectors 16.

u It will lfurther be seen that the inner surfaces of the walls of the sound conveyor adjacent its outlet present sucient body to Buport the tubes 15 which are suitably connectfer to extend and incline the thickened walls 12 of the* sound conveyor beyond the' tubes 15, as has been indicated by the reference numeral 17 whereby to meet and merge into the walls of the amplifyin chamber to provide a gradual expanse o the sound waves in their propagation.

It is to be noted that the flaring mouths of the auxiliary openi or passages 13 are of the sound conconstruction of the nerally in the same veyor and lead to a converging and concave formation in their outlet, and the inset ,being rounded a smooth passage is provi ed for the air motion conveying the sound waves. As in Figure 2, the auxiliai outlets are individually connected with t e tubes which extend into the side walls of the dolll) ilector, and thus it will be appreciated that Athese delectors or horns 16 reccivetheir only support through the medium of the tubes 15.

Now with e view of preventing a distortion or improper projection of the sound waves from Within the horns 16 it will be noted that. preferably provide a delecting and dividqJ ing Wall 18 in each of the same which has its outer end 19 extending at a oint sub stantially intermediate its' side e ges for a distencecovering and beyond the tube openings for the purpose of providing a gradual coalescence of the sound Waves entering each horn from the individual tubes thereby avoiding agitated air motion to destroy the Wave motions resulting from abrupt coalescence.

might readily be resorted to Without in the least departing from the spirit of my in vention which I claim as:

A sound clarifier, including an amplifying member, a pair of deflector horns within said member disposed one above the other, a dsflector member within each of said horns, a pair of tubes connected to each of said horns and opening into the rear end of each of said deector horns, sloping Walls on' said deflector member within each of said horns associated with the tubularopening to direct the sound forward within the horn, and a plurality of assages formed in the Walls of the ampli er member, the inner ends of said tubes being mounted in the Wall in line Ywith the outer ends of said passages, where1 by the tubes and the arms are supported from the Walls of the amplifier member.
