Description
Oct. 9, 1951 F. B. RQMERO JET PROP-EILLED VESSEL Filed Sept. 22, 1947 Patented Oct. 9, 1951 UNITED STATES PATENT OFFICE JET-PROPELLED- VESSEL Frederick B. Romero, Washington, D. 0.
Application September 22, 1947, Serial No. 775,442
.and rearwardly is made with two water jet tubes,
which at their forward ends open within the vessel to fit a bushing mechanism of application of Ser. No. 648,802, filed February 14, 1946; and
also open downwardly through the crafts bottom to admit water which is forced rearwardly through the said jet tubes, which open through the crafts stern plates. Moreover, this application is a continuation-in-part of application Serial Number 643,981, filed January 29, 1946, now Patent No. 2,550,298, dated April 24, 1951.
Objects of the present invention include 'a boat or vessel with jet tubes of the type set forth wherein the jet tubes are supported close to the crafts bottom and equidistant from the longitudinal centerline and occup approximately one-third of the crafts total length, and thereby offer potential jet or jet driving force of an unusually great power. A further object of the invention is generally to improve the construction of boats and vessels with water jet drive systems-of the type herewith set forth.
The herewith enclosed drawing consists of three illustrative figures wherein the same structural parts are indicated by the same number.
Fig. 1 is an elevation stern view of the water craft, boat, or vessel.
Fig. 2 is a side elevation partially in section of the water craft, boat or vessel.
Fig. 3 is a bottom plan view of the Water craft, boat, or vessel,
In this construction illustrated in Figs. 1, 2, and 3, as applied to a water jet propelled water craft, to which the invention is more particularly intended, the water craft is comprised of the upper deck I, the shell 2, which includes the stern plates 3, 4, 5, and 6, and center channel plates l and I1, the central keels 9, the bilge keels 8, the forward center keels I8 and 2|, the platform deck is, the five transverse fiat-bar strength and stabilizing members if the rudder stock under-support H, the rudder E3, the rudder stock i l, the jet tubes 12, with their forward end bottom openings 20, and their forward end bushing apertures i6, which become occupied by the bushing mechanism revealed in application of Ser. No. 648,802, filed February 14, 1946.
The boats deck and shell plates are adequately supported by frame members. All lines and points of structural securement are bonded by welding. The boats center channel, it will be noticed occupies the rearward approximate two-thirds of (c1. ire-5s) the crafts total length, and forwardly the channels top plate IT, curves downwardly and forwardly to become contiguous with the forward bottom keel 21. The medial surfaces of'the channels side plates 1, are coextensive with the medial surfaces of the central keels 9, the lateral surfaces of said central keels meet the crafts bottom shell along a line at a higher elevation than the crafts lowermost bottom shell, thereby forming a longitudinally extensive inverted somewhat V-shaped space along the crafts bottom, which when filled with water as occurs when the water craft is afloat, provides a transverse stabilizing effect. Further stability is provided by five transverse fiat-bar members l0, extending between the lateral lines of lowest elevation along the crafts bottom and piercing the central keels 9, with which they are made continuous by welding. These five flat-bar -members l0, provide not only transverse stability but also longitudinal stability preventing quick and much pitching motion of the craft on rough surfaced water. The central keels 9 and the bilge keels 8 provide transverse stability, preventing quick and much rolling motion of the craft on rough surfaced water.
The two jet tubes I2 are properly supported and welded to the inside of the crafts frame and shell structure, and occupy the rearward approximate one-third of the vessels total length, and they open as shown through the crafts bottom, formed by apertures 20, in Fig. 3. In Figs. 1, 2, and 3, stern plates 5, it will be noticed, provide a flared or diverging rear end in the center channel, and thereby providing adequate space for movement of the rudder l3. The crafts stern is completed by transverse stern plates 3, 4, and 6.
Forwardly, the center keel l8, together with other frame members provides adequate shell sustaining strength. The platform deck I9, is properly supported and provides a top for inner bottom tanks and a support for vessel powering equipment. In vessels of transoceanic size a plurality of decks are provided with proper means of support and are made with properly placed hatches, watertight hatch covers and between deck Stairways. And also in vessels of yacht size and larger, there are provided the commonly known superstructures such as the pilot house, bridge deck, etc., but such structures in themselves are not novel, and therefore, are not shown.
Iclaim:
1. In a water jet propelled vessel having a hull bottom formed to provide a pair of keels along 3 the turn of the bilge along each side of the hull and throughout the after two-thirds of the length of the hull, longitudinally directed V-shaped channels formed in the bottom of the hull substantially co-extensive in length with said bilge keels, parallel to said bilge keels along each side of the hull and adjacent the bilge keels, a pair of central keels parallel to said V-shaped channels, one of each pair forming the inboard side of one of said V-shaped channels and extending below the lowest point in the hull, a central channel between the central keels, the central channet substantially co-extensive in length with said bilge keels, the V-shaped channel and central keels, and a plurality of flat-bar members extending transversely of the open sides of the channels, the fiat portions lying substantially in the same horizontal plane to afiord increased stability; that improvement which comprises water jet propulsion tubes within the hull and along the V-shaped channels, said tubes terminating at their forward end two-thirds of the length of the vessel from the bow in openings in the V-shaped channels and terminating at their after end at the stern of the vessel and each side of 4 the central channel, said tubes formed to receive a propeller whereb water may be discharged adjacent the open end of the central channel.
2. A jet propelled vessel as claimed in claim 1 wherein the after sides of the central channel are formed to flare outwardly at the rear end of said channel.
3. A jet propelled vessel as claimed in claim 1 wherein the after ends of the tubes are formed to provide constricted portions.
