연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Speed controlling apparatus particularly is disclosed to be mounted with respect to a boat motor in a position confronting the propeller wash of the boat's motor, whereby the thrust imparted to the water by the motor's propeller is significantly deflected or attenuated, thus reducing boat speed. The contemplated speed controlling apparatus includes a mounting plate adapted to be mounted upon the motor housing, and a deflection or trolling plate coupled to said mounting plate to be disposable between a first position confronting the propeller wash, and a second position disposed remotely from the path of the propeller wash. In a first aspect of this invention, the deflection plate is variably disposed with respect to the path of the propeller wash and in particular, may be disposed at variable depths within the water. The deflection plate includes at least one vane extending therefrom having a portion that extends below the bottom most edge of the deflection plate to be directly disposed within the propeller's wash to impart the desired controlling action upon the boat's movement.

1. Speed controlling apparatus adapted to be mounted with respect to a boat's motor, which drives a propeller for forming a wash directed along a path rearwardly of the boat's stern, said apparatus comprising: a. a deflection plate; b. means for mounting said deflection plate with respect to the boat's motor for movement between a first position confronting the propeller wash and a second position remote from the path of the propeller wash; and c. at least one vane fixedly attached to said deflection plate and extending in a direction along and into the path of the propeller wash for providing increased stability and control of the boat's movement through water and said vane comprises an extended portion that extends below the lower most edge of the said deflection plate and into the propeller wash. 2. Speed controlling apparatus as claimed in claim 1, wherein there is included a plurality of said vanes, said vanes disposed substantially parallel to each other. 3. Speed controlling apparatus as claimed in claim 1, wherein said means for mounting includes means for releasably and variably coupling said deflection plate with respect to said boat's motor so that said deflection plate may be selectively positioned with respect to the path of the propeller wash. 4. Speed controlling apparatus as claimed in claim 3, wherein said vane comprises an extended portion that extends below the lower most edge of said deflection plate, and said mounting means disposes said deflection plate such that its lower most edge is disposed to partially confront the propeller wash and to permit said extended portion of said vane to extend into and to be operative upon the propeller wash to enhance boat stability. 5. Speed controlling apparatus as claimed in claim 1, wherein there is included a plurality of vanes. 6. Speed controlling apparatus as claimed in claim 1, wherein said vane has a leading edge slanted with respect to said path, and a trailing edge slanted with respect to said path. 7. Speed controlling apparatus as claimed in claim 1, wherein the propeller has a given diameter, and said deflection plate has a minimum dimension disposed perpendicular to said path that is equal to or greater than the given propeller diameter. 8. Speed controlling apparatus as claimed in claim 1, wherein: said means for mounting comprises a mounting plate adapted to be mounted to the boat's motor and including at least one flange, and a locking plate disposable between a first locking position wherein said locking plate presents a locking surface to retain said deflection plate in its first position and a second released position wherein said locking surface is removed from said deflection plate thereby permitting said deflection plate to move toward its second position under the influence of the propeller's wash. 9. Speed controlling apparatus as claimed in claim 8, wherein there is further included resilient means for biasing said locking plate in to its locking position with respect to said deflection plate. 10. Speed controlling apparatus as claimed in claim 9, wherein said resilient means includes a stud element loosely disposed through openings within said flange and said locking plate and a spring disposed about said stud for resiliently disposing said locking plate toward its first locking position. 11. Speed controlling apparatus as claimed in claim 10, wherein there is further included a fastening member affixed to said flange and presenting a pivoting edge to said locking member, whereby said locking member may be rotatably disposed about said pivoting edge from said first locking position to said second released position. 12. Speed controlling apparatus as claimed in claim 11, wherein there is included a cord having one end attached to said locking plate, whereby a force may be exerted via said cord to dispose said locking plate from its first locking position to its released position. 13. Speed controlling apparatus as claimed in claim 1, wherein said means for mounting includes means for releasably and variably coupling said deflection plate with respect to said boat's motor so that said deflection plate may be selectively positioned with respect to the path of the propeller wash. 14. Speed controlling apparatus as claimed in claim 13, wherein said means for mounting comprises a mounting plate adapted to be fixedly secured with respect to the boat's stern, a rotatable member rotatively coupled to said mounting plate for movement between said first and second positions, and releasable fastening means for variably coupling said deflection plate to said rotatable member in a selected one of a plurality of positions. 15. Speed controlling apparatus as claimed in claim 1, wherein said vane has a leading edge slanted with respect to said path, and a trailing edge slanted with respect to said path. 16.
