Ancillary objects and features of novelty will become apparentto those skilled in the art, in following the description of the preferred forms or" the invention, illustrated in the accompanying drawings, wherein:
Figure'l is a front view of a boat.- having one form of the invention associated-"therewith;

Figure 5 is a sectional view illustrating a second form of the invention.,
This invention has been developed to provide. a device for the purpose of increasing engine efficiency and also for preventing-or. substantially I: obviating undesired fumes and odors from entering the passenger carrying portions of a boat.
,to swing onlyqa-selectedddistance when'itwill' strike either the-stop- 28 or --the:",uppe'r portion of the housing-a Inspection' of "Figure '2 "clearly discloses two of sucirvalvrezsrone bein'g'positioned within the said-4000p: l8 Whilethe"other"is po=" ;sitioned in thesaidscoop-l 8:-
Means forstrainingthe-incoming fluid is pro vlded at each end of -the-said-'scoop"or housing"" HLJEhe preferred-means-consists of a grate '24 being attached -by-=suitable--scr6ws' 2 E *or'th'e like. Thi's, Of- 'COUISBfTEIldGIS the-gratedetachable-in order that it maybe-removed ifiound desirable or maybe repIaced---byone -h-avinglarger or' smaller apertures or opening therein.
A collar: 28 issupplied atan'ope'ning in 'the""f said housing It and-has-a section30 of a con Y duit secured thereto;- This section'may be at f tached through themedium of alap joint as dicated at'32.
A recessed =por-tion-=34-is suppliedinthesec tiontiiand has -a-slider valve 35 'positio'ned'there j in. A cage- 38 is assoeiatedwith'the section-3O opposite the said recessed portion' 34 whereinthe said sliden-valve-or valve plate*36'may'bes'e-' lectively -positioned- By' sliding *the" valve plate 36 Back and forth across "the same sectibn3fl, the rate and-quantity of flow therethrough 'rnay be selectively-regu1ated-.--The flow is produced" due to the forward travelof the boatto' 'whi'cli'itj is attached; the-said housing 14 being" submerged:-
In-order to regulate -'the valve plate' 36i'sielec tively, +a threaded shank" '40 is rotata-bly' jou nalled therein andreceived' 'in a" suitable internally threaded boss 4-2 securedto the saidlvalve plate recipient 38s =A suitabl'e k'nobbrhandle may be fixed to the said threaded shanli flfor manual actuation-purposes; h N h h A second curvedsection-te ls attaclidftc' the said sectioir tfl iri-"order conduit and of course the like may be'used ln Athimsecuoiiaa' i g 1se ea ,0 H which 'is passe'd hulP iFi'gu 6' attached to the said section 46 and tapers toward the end portion thereof. The conventional exhaust pipe 52 extends within the said section 48 and is supported by means of the boss 54, either attached to or formed integral with the said section 48. I
Means for supporting the terminal portion of the exhaust pipe 52 adjacent but not at the ter- -minal portion of the said section 48 is supplied.
The preferred means consists of a web 56 immovably positioned therein with the exhaust pipe 52 rigidly associated therewith. It will be noted that the exhaust pipe 52 is curved in order to accommodate various requirements and considerations of the invention. This curve is supplied in order to direct the exhaust toward the rear portion of the boat and further, the terminal portion of the said gooseneck-element 18 is just at the water line in order that water rushing through the housing l4 and through the curved conduit may admix with the said exhaust in orderto maintain it within the liquid for a short duration while the boat is moving steadily away from that particular locality. Of course, a small amount of the exhaust gas is retained in the water and the remainder of the exhaust gas requires some time to bubble through the liquid medium. This permits the boat or the like to be moved to another location more distant from the fumes than it would ordinarily be.
Referring now to Figure 5, a second form of the invention is illustrated. This form may be used wherein straight or substantially straight exhaust pipes are supplied. The difierentiating features of this embodiment of the invention include the absence of the curved terminal 59 of the gooseneck section or element and the substantially straight, conventional exhaust pipe 68 for use in association therewith.
Another diiferentiating feature is the actual configuration of the housing 62 utilizing only half of the housing illustrated in Figure 2. This housing has the general configuration of only one scoop such as 16 and therefore, does not require the services and utility of the pivoted valves 22 and the stops 20 therefor. The scoop or housing 62 may have the grate 24 associated therewith in order to strain the liquid before it proceeds through the apparatus thereby preventing clogg-ing or the like.
The remainder of the structure is identical to that disclosed and described in connection with the first form of the invention. It will be noted that this second form of the invention can and is used only in association with boats which travel in a single direction. The form of the invention illustrated in Figure 2 may well be subjected for use in association with ferries and the like which generally travel in a forward and backward direction about equally in distance.
In operation of the device shown in Figure 5, the engine of the boat is actuated. Exhaust flows as normal through the exhaust pipe 68. This flow is aided by the suction created by the water rushing through the conduit 48 (see Figure 2). The water is controlled by the valve shown in Figure 5, the control being as to quantity of water flow through the scoop 62.
As disclosed in Figure 2, the conduit 48 narrows to the point of egress of the liquid and at the place where the exhaust pipe 52 terminates.
In operation of the form of the invention shown in Figure 2 the distinction is that the Valves 22 are operated. When one valve is down as shown in this figure, the liquid is allowed to enter the scoop or housing for passage into the conduit 48. When the boat is operated in the reverse direction, as a ferry boat in operation, said one valve 22 is closed and the other is open.
Having described the invention what is claimed as new is:
1. In combination with the hull of a boat and an exhaust pipe from the engine of said boat, a device for enhancing the flow of exhaust gases through said exhaust pipe comprising a housing with means for attaching said housing to the exterior of said hull, said housing having openings at the front and rear ends thereof, a first valve carried by said housing and controlling one of said openings and a second valve carried by said housing and controlling the other of said openings, a conduit attached in communication with said housing intermediate the ends thereof to conduct liquid from said housing, said exhaust pipe extending into and located concentrically within a portion of said conduit and having its open end arranged to deliver engine exhaust gases in the same direction as the direction of flow of fluid through said conduit so that the passage of fluid through said conduit assists in discharging exhaust gases from said exhaust pipe.
2. The combination of claim 1 and a control valve in said conduit, and a web disposed in said conduit supporting the exhaust pipe in concentric relation with said conduit.
3. In combination with the hull of a boat and an exhaust pipe from the engine of said boat, a device for enhancing the flow of exhaust gases through said exhaust pipe, said device comprising a housing with means, for attaching said housing to the exterior of said hull, said housing having a front opening, said housing having a discharge opening spaced from said front opening, a conduit attached in communication with said discharge opening, a valve carried by said conduit and arranged to control the passage of water through said housing and said conduit, said exhaust pipe extending into and. located concentrically within a portion of said conduit and having its open end arranged to deliver engine exhaust gases in the same direction as the direction of flow of Water through said conduit so that the passage of water through said conduit assists in discharging exhaust gases from said exhaust pipe, and means carried by said conduit to support said exhaust pipe within said conduit.
