The watercraft includes an interiorly configured engine compartment operated by a throttle, a rear transom forming a portion of the watercraft's structure, a rearwardly extending tail pipe and a bilge line associated with the tail pipe. Elements of the assembly include a bilge pump valve adapted to communicate the interiorly configured engine compartment with the rearwardly extending tail pipe and via the associated bilge line. A water flow diversion member has a first end and a second end, a flexible boot adaptor engaging the first end with the extending end of the tail pipe, a second end of the diversion member extending in communicable and arcuate fashion from the first end. A plurality of tensioning members extend from the flow diversion member and are adapted for securing to the transom, the tensioning members compress the first end of the diversion member and the interconnecting boot adapter against the exhaust side of a jet pump housing while inserting through a steering nozzle (or boot) secured to the outlet of the tail pipe. A flexible length of conduit threadably engages the second end of the flow diversion member and a flow distribution member is in turn threadably engaged with the second end of the length of conduit. Upon actuating the bilge pump valve from an open position to a closed position and applying the throttle, the assembly issues a pressurized flow of water through the flow distribution member and through the outlet nipple.
Description
- 1. Field of the Invention
- The present invention relates generally to water ejection systems, particularly those capable of being utilized with an existing personal watercraft. More particularly, the present invention discloses an improved and universally adaptable valve, hose and nozzle assembly for use with a personal watercraft and which enables the generation of a jet stream of water, while at the same time preventing the engine compartment of the watercraft from filling with water and sinking.
- 2. Description of the Prior Art
- The prior art is well documented with variations of water projection and propulsion systems, particularly of the type which can be utilized with existing personal watercraft devices. Applications for such a generated stream of pressurized water flow resulting from a watercraft exhaust include use by marine fire fighting units, in particular for maritime and waterfront fires, as well as varying types of recreational uses.
- U.S. Pat. No. 5,299,960, issued to Day, teaches an auxiliary water projector system for use on a jet propelled watercraft. Upon removal of the water steering nozzle (located at the exhaust of the watercraft) the auxiliary projector system is connected to the existing propulsion system. A thrust control valve is further positioned adjacent the remounted steering nozzle and, using the thrust control valve and a flow control valve, the operation of the watercraft and auxiliary water projector can be simultaneously controlled to include stationary, forward or reverse movement of the watercraft.
- U.S. Pat. No. 5,516,313, issued to Lumpkin, discloses a fire fighting accessory for a jet propulsion system and which diverts the water flow generated by the propulsion system for use as the fire fighting implement. The accessory is disclosed as capable of being attached to an existing fluid drive system in a non-interfering relationship with the steering nozzle of the jet. The accessory may also be mounted either downstream or upstream of the jet outlet and is controllable from within the vessel. In further embodiments, the accessory coupler is moved into and out of engagement with the drive unit or to direct water into either the jet outlet or the accessory coupler.
- Finally, U.S. Pat. No. 5,846,104, issued to Corcoran, teaches a water diverting apparatus for adaptation into a recreational motor ski vehicle. The diverting apparatus is constructed as a bell housing securable to the jet ski exhaust and including a hole through its top surface near an angled back end. A diverter assembly is provided, having lower, center and upper segments and, upon the diverting apparatus being mounted in place, operates without degrading either the speed or agile maneuvering of the motor ski vehicle.
- The present invention discloses a new and improved type of universally applicable valve, hose and nozzle assembly for incorporation into an existing personal watercraft. In particular, the present invention provides the combined advantages of portability and the ability to be easily sized, fitted and reattached to a watercraft vehicle, with a minimum of effort and without any significant disfiguration of the personal watercraft.
- Specifically, the watercraft includes an interiorly configured engine compartment operated by a throttle, a rear transom and a rearwardly extending tail pipe. The assembly includes a bilge pump valve adapted to communicate the interiorly configured engine compartment with the rearwardly extending tail pipe. An arcuately shaped water flow diversion member has a first end and a second end, a flexible boot adaptor engaging the first end with the extending end of the tail pipe and the second end extending in communicable and arcuate fashion from the first end and terminating in upwardly projecting fashion above the surface of the water.
- A plurality of tensioning members are employed for maintaining the diversion member and flexible boot in seal-tight fashion against the watercraft tail pipe and include individual linkage assembles extending from a flange portion defined on said diversion member. Each of the linkage assemblies engages an eyebolt projecting from a selected location on the transom of the watercraft.
- A flexible length of conduit is provided with first and second opposite ends, a first end of which threadably engages the second end of the flow diversion member. The flow distribution member is in turn threadably engageable with the second end of the length of conduit and may further include an outlet nipple. In one variant, the flow distribution member is provided as a pedestal supported unit, to which the first length of conduit is threadably engaged, and a further length of hose, or conduit, is secured to the outlet nipple (such as by threaded engagement). Alternatively, the distribution member may be configured as a threadably attachable and substantially pistol shaped unit and which may further include handle, stock and barrel portions.
- In use, the bilge pump valve is actuated from an open position to a closed position and, upon applying the throttle to accelerate the watercraft's engine, the assembly issues a pressurized flow of water through the flow distribution member and its associated outlet nipple. In this manner, water is prevented from back-flowing (in the direction of least pressure) into the engine compartment and sinking the watercraft during use of the assembly.

conduit 32 is provided having afirst end 34 and asecond end 36. Thefirst end 34, as best shown in the cutaway of FIG. 4, provides a first engageable end which secures to the associatedsecond end 24 of the arcuately configured and flowdiversion member 20. Referring further to the cutaway section of theconduit 32 illustrated in FIG. 4, an internally wound and coiledspring configuration 33 may be employed for providing structural integrity to the conduit and to maintain its fluidly communicating properties. It is however also envisioned that the conduit can be provided in any desirable configuration and dimension without departing from the scope of the invention. - The ends of the conduit, such as again shown at24, can be configured to engage, such as in a twist and lock fashion, relative to such as the associated
end 24 of theflow diversion member 20. Alternatively, and referring further again to FIG. 2, the ends of the flexible and internally hollowed conduit (see again as represented by second end 36) may be provided with externally facingthreads 38. - A first variation of a flow distribution member is illustrated at40 in FIGS. 1 and 2 and is provided as a pedestal supporting
unit 40 having abase 42, an upwardly extending and internally hollowedbody 44 with aninlet 46 communicable with thesecond end 36 of theconduit 32, and an upwardly directedoutlet 48. As further best illustrated in the enlarged sectional view of FIG. 3, theoutlet 48 is further defined with additional anexterior facing threads 50 and anoutlet nipple 52 extending in terminating fashion. - An additional length of
conduit 54, referenced in solid in FIG. 1 and in phantom in FIG. 2, is attached over theoutlet nipple 52. In one preferred variant, the additional length ofconduit 54 is provided as a conventional garden hose and includes an internally threaded end (not specifically shown) which threadably engages over theexternal threads 50 associated with theoutlet 48 and extendingnipple 52 of theflow distribution member 40. Referring further to FIG. 6, anadapter 58 is illustrated which is internally hollowed with a first female threadedend 58 according to a first dimension and a second male threadedend 60 according to a second dimension. The adapter typically is provided in use with the threadedend 50 of the flow distribution member 40 (or even thesecond end 24 of the flow diversion member 20) and in order to selectively increase or decrease the diameter of the fitting for engaging the second conduit (or hose) 54 or, again in certain instances, the engaging end of thefirst conduit 32. - Referring to FIG. 7, an
alternate variant 62 of the flow diversion member is illustrated and which includes a substantially pistol shaped member. The pistol shapedmember 62 replaces the pedestal supportedmember 40 of the first preferred variant and includes ahandle portion 64 with a first internally threaded and inserting end 66 (such as for engaging the associating second and externally threadedend 38 of the first length of conduit 32). Additional components of thepistol member 62 include asupport portion 68, with terminatingshoulder stock 70, and a fluidlycommunicable barrel portion 72 terminating in an externally threadedoutlet 74. As illustrated in FIGS. 1 and 2, the second length of conduit 54 (garden hose) may be secured in threadably engageable fashion over the threadedoutlet 74 and, as again illustrated in FIG. 7, theadapter 56 can again be employed for changing theoutlet 74 dimension of thepistol member 62 for acceptingdifferent hose 54 configurations. It is also envisioned that other and additional types of flow distribution members can be employed with the assembly and without departing from the scope of the invention. - Referring again to FIGS. 1 and 2,

As further best illustrated in FIG. 4, theflange 82 includes three circumferentially spaced apertures for engaging each of thetensioning members tensioning members - Referring again to FIG. 2,
tension inducing components members eyebolts watercraft transom 16 for engaging the associatedtensioning members bolt 90 is provided as a first hull tiedown eyebolt extending in upward fashion in proximity to therear transom 16 and engages thelinkage mechanism 76. The additional pair ofeyebolts 92 and 94 extend in rearwardly facing fashion from thetransom 16 and are engaged, respectively, by extending ends of the second 78 and third 80 linkage mechanisms. It is also envisioned that other types of tensioning mechanisms, including flexible straps, can be employed or, alternatively, this feature can be deleted within the scope of the invention. - Referring again to FIG. 1,

The bilge line (18′, 18″) typically extends in an angular fashion (see again FIG. 8) relative to the maintailpipe exhaust line 18 and, as is known in the art, maintaining a vacuum pressure on the water during normal operation of the watercraft to keep the engine compartment from flooding. - A
handle 108 is provided and is accessible from an exterior location of thewatercraft 12 in order to be actuated from an open position to a closed position, prior to attachment and operation of the assembly. It has been determined in practice that thevalve 100 is a necessary component in that, otherwise, operation of the assembly would result in water flowing in a reverse (vacuum) direction through the bilge line (18′, 18″) strainer and into the engine compartment (this being determined to be the lowest path of fluid pressure) with the result being thewatercraft 12 sinking. - It is therefore evident that the present invention teaches a novel and useful valve, hose and nozzle assembly for use with a personal watercraft. Having described my invention, additional preferred embodiments will become apparent to those skilled in the art to which it pertains and without deviating from the scope of the appended claims.
