ALVA WILLIAMSON, or ATLANTIC, IOWA.

SOUNDING- HORNS.

Specification of Letters Patent.

' Patented Feb. 20, 1912'.

Application filed March 29, 1910. Serial me s.

To all whom it may concem:

Be it known thatl, ALVA WIILLAIMSQN, a citizen of the United States, and a resident of Atlantic, in the county of Cass and State of Iowa, have invented certain new and useful Improvements in Sounding Horns, of which the following is aspecification, ref erence being had to the accompanying drawmgs. y

The object of my invention is to provide simple, durable and inexpensive means,

whereby the intermittent exhaust from an explosive engine may be utilized to operate a wind instrument such as a horn in a continuous, even, and uniform manner and also to provide convenient means whereby an operator may, by foot pressure, open the valves for permitting the wind instrument to be sounded.

My invention conslsts in the construction, arrangement and combination of an explosive engine, of means whereby the. objects contemplated may be attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure l-shows a side view of my invention used in connection with an automo bile which is shown in dotted outline. Fig.

2 shows an enlarged, detail, side view ofan apparatus embodying my. inventionf iF-igu 3 shows a similar vleiifi partly in section. Fig. 4 shows an enlar ed, detail, sectional view of the valve device for opening and closing *the passageway leading to the storage chamber, and illustrating-1a modification. Fig. 5 shows a side view ofI-aH-device embodying my invention applied. to launch, the outline of the latter being in= dicated by dotted lines, and Fig. 6 shows a side'view of a device embodying my invention illustrating a modification.

- Referring to the accompanying drawings, I have'used the reference numeral 1 to indicate the exhaust pipe of: ani'zexplosive en-. 'gine. Gommunioatin'g"with, the exhaust pipe is-="a"-T-connection--3 and communicat-f "withfone branch ofthis T connecti on.=is "axpipe'2leading to a. muflier' 4: of ordinary vconstruction. Communicating withanother branch Uf'the T'-connectio'n 3 is a; duplex valve-casing 5 having valve seatsat both ends. .Slidingly mounted within the valve casmg 5 is a valve stem 10 having a valve 6 at one end and another valve '1 at the other. end. I provide 'for supporting the valve stem within the casing by means of two guidedevices 10. By this arrangement it 1s obvious that when the valves arein the posltion shown in Fig. 3,-all of the exploded gases passing through the exhaust pipe 1 will be directed through the muffler but when the valves are at their opposite limit of movement some of the exploded gases passing through the muffler will enter the interior of the valve casing 5 and be defiected downwardly through a pipe.. 15 at the center of the casing, the outer end of the casing being closed by the valve 7.

I provide for normally holding the valves in the position shown in Fig. 3 by means of a contractible coil spring 12 attached to the projecting end of the valve, stem 10. In order' to provide for opening the valve to permit the passage of the exploded gases through the pipe 15, I haveprovided a lever 11 fulcrumed to a suitable support and connected to the valve stem. This lever is provided with a rod 13,- whichrod is .attached to a foot lever 14 so that, by the op. erator pressing his foot upon the lever 14, the pressure of the spring 12 may be over ,come and the valves within the casing-.5 may be held to position for permitting some of the discharge of the explosive engineto pass into the pipe 15. Arranged 1n the pipe 1-5 is 'a check valve 16 of ordinary construction designed to freely permit the passage of exploded gases through the pipe 1 5,and ,to prevent them, from passing back, Communicating with the check valve 16 is. a pipe-.17 which leads to..a, cylindrical tank 18. -This tankis dividedinto two com partments; the compartment. 19; forming a compression chamber and the compartment.

20 forming an expansion chamberto which ga pa i g .i.=- 0 gh h compressio chamber to the expansio chamber? m ziyibe regulatedat, the will oi the operator.

I In the modification illustrated in Fig; 41, I

have provided means whereby allof the burned gases passing through the exhaust pipe will be directed into the storage cham her to thereby increase.the capacity of the j with the wind instruments. The modification consists of asliding hood 37 attached to the valve stem 10 and so arranged that When the valve is moved to its limit of movement toward the right, as shown in said figure, the

hood will completely close the portion of their-connection that extends to the mufller while permitting the entire quantity of burned gases. passing through the exhaust pipe to enter the valve casing 5.

In the modified form shown in Fig. ;6, the storage and escape chambers are indicated by the reference symbol 18. They are provided with a by-pass and controlling valve indicated by the symbol 21. A number of bosses are. shown on the escape chamber to indicate where the sounding horns may be attached. The muflier-is indicated bythe symbol 4 and has an escape pipe 1 admitted into it. Leading from the mufl'ler is the duplex valve casing .5 and extended from this casing is the pipe 15 provided with'a.

check valve 16 which also communicates tank..18. Within. the pipe 16 is a puppet valve" B of ordinary-constructionby which the burned. gases may be discharged when the-pressure thereon exceeds a certain predetermined amount. 1 By means of this .1 puppet valve B. I provide for automatically 5. chamber 19 and I so arrange the other parts regulating the pressure-within the storage that an excessive amount of the burned gases under pressure will be delivered through the .pipe 17, the surpl through the puppet valve B.

" In the modified form shown in Fig. '5, I

ator manipulates the foot lever 14 have illustrated a launch by dotted lines 111- dicatecl by the reference symbol .13 The remaining parts are-the same ashereinbefore described except that I employ a whistle 26. applied to the exhaust chamber 20 instead 0 the horns shown in the other forms of the invention. In practicaloperation and assuming that the explosive engine is running and that the- .exhausttherefrom is passingthrough the pipe 1, it is obvious that'when the valve 6 is inits closed position all of the burned gases will pass through the mufiler in the ordinary manner. -However when the oper-;

art of the products of combustion will pass t rough the pipe 15 into the storage chamber, The.

check valve 16 will prevent a back pressure upon the pipe 15 and retain burned gases under pressure in the chamber 19. This gas under pressure in the chamber 19 may pass out slowly through the valve 21 into the. exhaust chamber and from thence into the wind instrument. By this arrangement I however that if pipe 17 leading to the cylindricalv us escaping am enabled to obtain a continuous,-uniform and steady flow of burned gases through the wind instrument to produce a uniform, even sound which may be continued indefinitely so long as the engine is running. I

The particular form of the' uplex valve is not essential to the successful operation of my invention as it is obvious that various other means may be employed for directing cation with the exhaust pipe, saidexhaust pipe being provided with an outlet other.

than the one leading to the storage receptacle, a' manually operated, "valvedevice either into the storage receptacle orthrough the said outlet, a check valve interposed between the exhaust pipe and the storage receptacle to prevent the flow of gas from the storage receptacle to the-exhaust pipzing pressure equalizing receptacle, there a restricted passageway provided between said receptacle. and thestorage receptacle, and a wind instrument operatlvely connected with the equalizing receptacle, the peawherebythe exhaust gases may be directed sageway from-the equalizing receptacle 'to a the wind instrument being unobstructed, whereby gas. under fluctuating pressure in the exhaustipipe may either be discharged or directed into the storage receptacle, and

the said gas .under une ual pressure in the storage receptacle may e delivered to the wind instrument at a substantially uniform pressure, for the purposes stated. V

In a device of the class described, the combination of an engine exhaust pipe, an inelastic gas storage receptacle in communication with the exhaust-1 pipe, said exhaust pipe being provided with an outlet other .than the one leading to the storage receptacle, a manually operated valve device whereby the. exhaust gases may be directed either into the storage receptacleor' through said outlet, a check valve interposed between the exhaust pipe and the storage re-. ceptacle' to prevent the flow of gas from the storage receptacle to the exhaust pipe,
