Application filed July 13, 1923. Serial No. 651,228.

To all whom it may concern:

Be itknown that I, FRED N. NELSON, a citizen of the United States, and a resident of Seattle, King County, lVashingtomhave invented certain new and useful Improvements in Boats, of which the following is a specification.

This invention relates to improvements in boats, particularly in launches, fishing'or trolling boats,-and all similar types of vessels; the object of the invention being to provide non-sinkable self bailing boats, rendered so by the provision ofan air tight compartment between the bottom of the boat and a. lower deck or a false bottom and having automatic clearingscuppers of a novel typeof construction through which water entering the boat may readilydrain therefrom.

One of the principal objects of this invention resides in the construction of the scupper and a closure therefor and in thedetails of construction of means whereby the closure may be looked, as occasion arises, to

of water that may splash or break overthe'y boat.

Another object, resides in the provision, in fishing'or trolling boats, of a fish well, with means whereby it may be easily flushed.

-Other objects reside in the various details of construction and combination of parts embodied in the invention whereby a serviceable and very desirable type of construction is provided.

In accomplishing these and other objects of the invention, I have provided the improved construction, the preferred forms of which are illustrated in the accompanying drawings, wherein Figure 1 is a longitudinal sectional view of a boat constructed in accordance with the present invention.

Figure 2 is a plan view of the same.

Figure 3 is a detail view in longitudinal section, of a scupper of the preferred type of construction used in the boat.

Figure /l an enlarged plan view a part of the scupper, its closure and one of the closure locking devices.

Figure 5 is aside view, partly in section, illustrating the scupper closure hinge and a locking device.

Figure 6 is a detail, sectional view of the. valved ventilator of the engine housing.

Referring more in detail to the drawings 1 designates, in its entirety, a boat of a type embodied by the present invention. This may be of any desirable size and shape, designed to suit any specific purpose or condition, preferably it would be constructed of sheet metal but could be made of wood with satisfactory results.

Theboat comprises a hull 2 and a deck, or false bottom 3,-forming an air tight compartment 1 between the said deck and bottom of the boat. For small and intermediate sizes of vessels, this design permits placing the deck 3 above the normal water line,

and the distribution of the load and weight so as to obtain the proper metacentric height and seaworthiness'. 7

Located within the boat, at a desirable place, is a tank 6 wherein liquid fuel for an engine 7 is contained. Preferably, in boats of the-type illustrated, the tank would be located at the stern and the engine is contained within a closed, water tight housing 8 which would be located at the most desirable place according to the characteror uses to which the boat was to be put. The ,present drawing shows the engine locatedjust forwardlyof tank 7 and the housing 8 er;- tends partly above and partly below deck 3. The housing coveris equipped with a goose neck ventilator tube 10having a downturned end with a bell shaped mouth 11 wherein a ball valve 12 is supported by a wire 'cagef13. This ventilator construction permits ready inlet of air into the housing but should water splash over the a boat and into the ventilator spout, the ball will be auton'iatically seated to close the mouth of the-spout. The cover of the housing will be removable and provided with suitable doors to permit access to the engine.

A cabin 15 is provided in the bow of the boat and rearwardly of this is a storage well 16 that extends substantially below the deck. The upper portion extends above the deck and in its covering has two hatches 17. The si e wal s 1 at the Well extend p rallel w th the side 'railof the boat at spaced distances therefrom as shown in Figure 2, to provide aisles 19. v I

In order that the-boat will besel't-bailing, I have provided a plurality of scupper-s,

of that character shown in Figure 3, that are located at desirable points in the deck and in such direction that the motion ot'the boat will accelerate an outward flow of water therethrougha Preferably there would be one at each side of thestorago well and two at the stern of the boat, and they are located so as to discharge through the side walls of the hull just above the water line Each scupper comprises a substantially horizontal discharge tube 20 of a desirable or suitable size located below the deck 3 with its discharge end opening through the side wall or end of the hull. The opposite end is fixed to a metal ring that'in turn is fas'tened'to the under side of deck 3 in registration with a hole in the deckoit'; the same a size. This ring is of Z bar form and comprises a flange 21 that is riveted to the deck, a downwardly extending vertical portion 22 and anannular, inturned flange 23;

Located within the scupper tube and adaptedto seat against the under side otnthe flange 3 of thering is a closure 25 therefor of the floating valve type comprising a hollow metallic body, hingedly supported atone side-by means of arms 26 fixed thereto and to a depending bracket 27 that is tired to the flange 28; the connection between the arms and bracket consisting of a pin 28 that is fixed in the arms and is pivotally and slidably contained in a Vertical slot 30 in the bracket. This closure, or valve when not locked operates automatically to permit water to drain from the beat outwardly through the scupper, but checks all-inflow due to its buoyancy which causes it to be lifted and held over the opening. Should be desired to lock the valve in closed position, tightly against't-he ring flange this can be done by means of locking devices mounted on the flange :Each of these "consists of a rotatableclamping member comprising a v circular base or mounting flange 32 and a vertlcal shank with a laterally turned handle 34, at its upper end.

*Theclamps are held in position by means flange 32 7 through apertures 36 in the plates 'offlange plates that are flxed to flange 23 of the ring and which overlie the base the shanks 33 being extended Formed on the shanksof the locking devices arelaterally extending cam flanges 37 adapt ed, upon rotation of the shanks by means of their handles, to engage with the under sides ofholding plates 38 that are fixed to the upper side; wall of the elosurevalve 25, and to thereby lift and tighten the closure a ainst" the ring. vlded about the upper periphery of the ele- Gask'ets 39 may be prowell, I have provided two inlet pipes 40 and 41 which lead into the forward end of the welland through the forward side walls of the hull below the water line." These pipes are controlled by valves Adoperable from above the deck. Leading from the rear, lower cornersot the well, I have provided outlet pipes d6 and t? which discharge into the rearward scupper tubes. These are con trolled by. valveslS. The openings of these pipes into the well are covered by pertorated plates so as to prevent clogging and a. free outflow of water through the pipes. When the valves of the pipes are opened, water will flow forcibly int-o the well through the'forward pipe, it the boat is traveling forward, and will be drawn from thecwell through the rearward pipes by suction. 1

Boats of this type, and embodying all or anyone of the above described features can be made in various sizesiandshapesaccording to their particular use, and variouslde 'WEtlCl end' through. the deck and, at its rearwardfend: through'the hull, a float valve within the tube operable automatically to closed'position to prevent an inflowot water, and locking means for retaining the valve closed. i

In a boat having a deck openingI a flanged-ringfixed'to the deck inregistration with' the opening, a scupper, tube leading from the said opemng. outwardly through the hull'of the boat, a floatable closure hinged- .ly mounted,v within the tube to; swing between open and closed positions against the ring flange and clamping means whereby the closure may be retained in closed position. i

3. In a boat con'lprising a deck having an opening, a scupper mounting ring fixed to the deck in registration with the opening and comprising an inturned, annular flange, a scupper tube having its inlet end mounted about'and secured to said ring and its disehargeend opening through the stern of the boat,v a floatable closure for the scupper mounted therein,a supporting bracket fixed to the said, ringand an arm liked to the closure having a slidable and pivotal connection with the supporting bracket whereby the float may be moved bodily from and toward the opening and clamping devices for locking the closure in closed position.

4. In a boat comprising a deck having an opening, a scupper mounting ring fixed to the deck in registration With the opening; said ring comprising an inturned annular flange, a scupper tube having its inlet end mounted about and secured to said ring and its discharge end opening through the hull of the boat, a floatable closure for the soupper tube mounted therein having support ing arms at one side, a supporting bracket fixed to the said ring having a vertical slot, a pin extended through said arms andslot to hingedly secure the closure While permitting it to move bodily toward and from the ring, clamping devices mounted on-the ring, and plates fixed on the closure to be engaged by said clamping means to hold the closure in closed position.
