To all whom t may concern.'
Be it known that I, JOHN HERMANBRETT- HAWK, a citizen of the United States, and
a residentof 1Westchester, county of Bronx, city and State of New York, have invented f certain new and uful Improvements in plarger scale.
eratingl Sounders, of which the following is a specication.
While applicableto all motors and engines,
.stationary or mobile, in which a partial vacuum is created incidentalto the operation thereof, my improvements are especially adapted to internal combustion motors, and, particularly to those used for the propulsion.
of automobiles and other vehicles, whether land or marine. f
The distinctive feature of my'invention consists essentiallyl in utilizing the partial vacuum incidentally1 created during the operation of a. motor (taking the latter term in its broader sense) to actuate a sounding device by a current of atmospheric air, inducted or suckedy through said sounding de vice by means of said motor vacuum as h ereinafter more fully set f forth,`subsi dia ry features relating to certain minor details involved in the practical application of the principle stated,whereby e'ective results are attained, and provision made for the regulation of the toneand pitch of the sounding medium. i

myself thereto in the abstract, since the princ iple involved is adaptable, as heretofore intiiiiated, to any engine or motor, the operation of which involves the creation of an available partial vacuumi. e., having a chamber or' part in the casing in which the interna-l pressure is reduced below that of the extraneous atmosphere.
Thus in Figs. 1 and 2, of the drawings, l show by 'way of exemplification, the carbureter C, and intake manifold C', of a plural of ordinary and well known construction and operation, it being 4 understood that the intake manifold C', communicates inthe usual manner with the inlet valves which admit'the admixture of fuel gas and air to the compression and combustion chambers of the piston cylinders, the suction created by the intake strokes of the pistons creating and maintaining a partial vacuum within said manifold Cf, as and for. reasons well known in the art. In the case of multiple cylinder internal combustion engines this partial vacuum in the intake mani old is practically continuously uniform, and rieliable vfor the purpose for which l make it available,f. enf-for the actuation,
by atmospheric air induction, of a suitable sounding device S, duct-connected as at d, with said intake manifold C.
Obviously various forms and constructions of sounding devices S, may be utilized for the purpose, provided they are adapted to be actuated by air induction, so that l do not limit myself in this respect. In the drawings, by way of exemplification, l have shown a simple forin of sounding device of the horn type, provided with a vibratoi'y element e, consisting of what may be designated as a reed plate positioned transversely with relation to an inlet port t', constituted by the inner end of pipe or duct d", the outer extremity of which is screw-connected with a control valve l, which is interposed between it and the pipe or duct di, which connects directly with-the manifold C', as aforesaid,said control valve K, being manipulated as required by a connection rod k, eX- tending into available proximity to lthe normal position of the operator.
Any desired form `and'coi'istruction of control valve K, maybe used for the purpose, provided it is adapted to open and close, or otherwise regulate, communication between the soundin device S, and the intake inanifold C.
he duct d, ,communicating di= rectly with the latter, may be of less diaml C', and prevent the clogging of the sounding element e, that might otherwise occur 1f it were exposed suddenly and directly to the full inductive torce of the motor vacuum suction.
ln order to regulate the position of the linlet port c', with accuracy with relation to the vibratory sounding element e, provision is made for adjustment in this respect. Thus the inlet duct d', may be made adjustable with relation to the sounding element e, or vice versa. ln the construction shown in the drawings either alternative may be resorted to since the horn k, is supported on a flanged base b, the hub b', of which is female screw threaded to fit and engage with a peripheral thread on said inlet duct d',-` the vibratory element e, being rigidly attached to the horn L. Hence by rotating the horn h, in one4 direction or *the other, the said vibratory element e, may be positioned with accuracy with relation to the inlet port i, so as to augment or reduce the volume of air admitted and sound produced, as required'.
The pitch of the sound produced by the induction of air is regulated by the tension to' which said vibrating element 'is subjected. To provide for this the ends of said vibra- 'tory element e, are clamped between serrated jaw plates j, y', (see Figs. 5, 6, and 7) mounted on the` inner ends of adjustable supporting and tension screws a, a, journaled in brous insulating bushings h', h", inserted for the purpose'in the sides of the horn h,'said bushings h', h, preventing the transmission of sound, vibrations from the sounding element e, through said tension and supporting screws a, to the horn, which is usually metallic; By this means the ele ment e is drawn more or less taut by means `of the screw and thus the tension of such i element is adjusted..
llt is to be understood that by the term sounding element as herein used mean to 'designate yany element adapted to produce sound vibrations by means ott an in.- ductive 'current of atmospheric air superin- Lasagne duced by motor-created partial vacuum substantially as herein set forth.
IThe air admitted to the intake manifold C', through my inductive sounding device S,
is relatively so small in volume as to be negligible. As a matter of 'fact it usuallyis eiicacious in promoting more perfect combustion 'within the motor, because as a rule the admixture of air and hydrocarbon derived from the carbureter is too rich in hydrocarbon, so that my system of inductive sounding may be designated as self-supporting in that it does not detract from, but rathertends to add to, the power and'eiiyciency of the motor.'
Another advantage attained by my system of inductive sounding is that a minimum amount of power is required for the purpose because the sounding element is actuated by atmospheric pressure and not against it, as heretofore. ln. other words, I utilize the fourteen pounds normal lpressure of the atmosphere instead of wasting power in overcoming same.
y Furthermore my system is conducive to simplicity and chea ness of construction and installing of signa ing means,-the essential operative parts being few and not liable to deran ement by use.
What claim as In invention and desire to secure by 'letters atent is,
1. A signal device of the character desi nated, comprising a horn, a vibratory sounding element located therein, and an air in` duction conduit having an inlet port positioned in coperative relation to said sounding element, together with means for adjusting the distance between said sounding element and said'air inlet port and means attached to opposite points of said element 'for regulating the tension of said sounding element, for the purpose described.
