To all whom it may;concerh Be it known that I, SOLOMQNJ-RGISOFSKY, a citizen of the United Statesiresidingat Brooklyn, in the county of Kings and State of New York, have invented certain new and useful. Improvements in Diaphragm 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 characters of reference marked thereon, which form a part of'this specification. The present invent-ion relates, generally,

to improvements in horns, signals, alarms,

and the like; and the invention relates, more particularly, to a novel construction of born,

or the like, in which the sound is accomplished by mechanically agitating a diaphragm to generate sound waves of high penetrating qii'ality'.

The principal object of the present invention is to provide a simple and efiicient construction of alarm horn, or the like, of few parts and simple in operation.

A further object of this invention is to provide a, novel means for, agitating the sound wave producing diaphragm; and, furthermore, a means'whereby saidagitab ing means may be easily adjusted to cause the production of the desired note or tone of said alarm-horn.

Other objects of this invention not at this time more particularly enumerated will be clearly understood from the following detaileddescription of the present invention.

With-the-various objects of the present invention in View, the said invention consists, generally, in the novel construction of alarmhorn, or the like, hereinafter set forth; and, the inventionronsists, furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construct-ion of the same, all of be morefully described in the following specification, and then'finally embodied in the clauses of the claim which are appended to and which form an essential partof the said specification,

The invention is clearly illustrated'in the accompanying drawings, in which: a

npp liqatton filed October 22, 1910. I Serial No. 588,431.

I like, made according to and embodying the principles of the present invention, the

sound amplifying horn-body being shownin longitudinal section; Fig. 2,,is a rear-end view of the same; and, Fig. his a horizontal cross-section of the same taken on line 3- in said Fig. 2, looking in a downwardly directi on.

Similar characters of reference are employed in all of the herein-above described views to indicate corresponding parts.

Referring now to the several figures of the "drawings, the reference-character lindicates the complete alarm-horn, or the like, made according to and embodying the principles of this invention, the said alarm-horn, or.

the like, comprising a shell-like body or cas ing 2 being open at one end, said shell-like body or easin being provided with an outwardly exten ing-annula r flange 3, the inner side of which forms a seat. flange being in turn cry with a rim or'flange 4 extending at right angles thereto. Arranged upon said seat','

formed by said annular flange 3, soas to extend across the opening or said shell-l1ke body or, casing "f is a diaphragm '5, the mar sald flange 3 by'means of solder 7, or (ither suitable fastening means. The referencecharacter 8 indicates a cover-member provided with an opening 9 registering over or above said diaphragm 5. Said opening 9 is surrounded by a suitable shoulder or collar 10 extending outwardly from the outer face of said cover-member. 'Said cover-member S is further provided at its periphery with a Said annular I provided at its periph- ,ginal edges 6 of which may be secured to 4 rim or flange 11 extending at right angles 1 thereto, and adapted to engage and be secured to said rim or flange 4 connected with the flange 3 of said shell-like body or casing 2 to properly inclose or cover said diaphragm. Arranged in the body of said member 8 are a plurality of screws 12, g or other similar fastening devices, the same being" adapted to engage the margins of said diaphragm .5 to serve as an additional "holding means for firm'ly binding said diaphragm upon the seat f rmed by said flange -'3 of said shell-like b0 or casing 2. Se-

cured to said cover-mom er 8 in any suitable @finner is an outwardl extendin bracket which said a arm-horn may be supported in a pro or location 11 on a vehicle or other place w ereit is desired to use the same. .Secured by means of setscrews 1st, or any other suitable fastening means, upon said shoulder or collar 10 of said eover-inemberis the neck of an amplitying horn or megaphone 15, so arranged that it registers with said opening 9 over or above said diaphragm 5, the purpose of'said horn. or megaphone being clearly-apparent as a means for amplifying' concentrating and directing the sound waves generated by said diaphragmo; Said diaphragm 5 is provided with. a pair of agitating-elen-ients, each comprising a foot-piece or base 16 adapted to be secured to'. and abut against the rear or inner side of said diaphragm 5,

a rearwardly extending arm 17 connected with said foot-piece, and contact'finger 18 connected with the free end of said arms 17. The means for securing said toot-piece or base in its proper relation with said diahra m consists. ireterabl of a )fl'lI of l 9 studs or shanks 19 adapted to be passed through holes or openings in the body of said diaphragm arranged-for their reception, and the free ends of the same then be-' -ing riyeted over in the form of a retainingranged in cmmection with mg '29. ()no end of saidshattlilext-ends inhead 20-upon theopp'osite' surface of said diaphragm 5. Each of said rearwardly extending arms 17 is provided with a hole'or opening 21 the inner edges of which are formed with a chamfer 22 adapted to provide a seat for the head 23 of an adjusting pin 94. The free end of said adjusting pin v 23 extends through a suitable opening in the walls of said shell-like body or casing 2, provided for that purpose, and said free end is provided with a suitable screw-thread 25 upon which is arranged an adjusting-nut 26 which bears against. the outer surface of said shell-like body or casing 2. One of the sides of said shell-like body or casing 2 is provided with a hole or opening the marginal edge of which is provided with an outvvardly extending shoulder or collar 27. Arranged in said hole or opening and secured to said shoulder or collar by means of suitably arranged retaining screws 28, or

the like, is the casing 25) of a small electric motor -30. Said casing :29 being provided with suitably arranged binding-posts 31 for securing in proper connection the current. supplying or conveying wires 32. The a rmature o'l? said motor rotates a shaft 33 mounted in suitz'ihlc hmiriug pieces rlel armotor-caswardly into lh: interior of said shelldike body or casing Secured in any suitable manner upon said inner end ol said shaft. 33, which is within said shell-like body or casing 52, is u vil'n'ntornvhcel 35, having upon its periphery any desired number of eaurmembers 36. hild viln-ator-wheel 35 is arranged in such a nuiuoer that when the same rotates its cam-men'ibers 36 are brought into contact with said contact-fin gcrs 18 of said agitating elements, whereby the same are Caused to vibrate in a manner to transmit such vibrations to said diaphragm 5, so that the latter is in turn agitated or vibrated to produce the desired sound-waves. It will be clearly evident from an inspection of Fig. dot the accompanying drawings, that the adjusting means, comprised in said adjusting pins 24: and their respective nuts 26, may be so operated as to move a greater or less portion of said contact-fingers 18 into the path of said cammembers 36 of said vibrator-wheel 35. whereby a greater or less vibration or agitation of said diaphragm 5tmay be brought about and afconsequent regulation of the pitch or tonal sound waves produced by said diaphragm maybe obtained. It will thus. be evident that the novel alarm-horn, or the like, may be tuned to produce the desired sound having the desired degree of penetrability and carrying power sufiicient to produce a proper alarm. It wilh furthermore, be understood that the leverage ofthe agitating elements which are secured upon to give the warning desired to be produced.

- I am fully aware that changes may be made in the various arrangements and coin- .binations of the several devices and parts,

as well as in the details of the construction of the same without departing from the scope of my present invention, as described in the foregoing specification and as defined in the claims which are appended thereto.
