Driginal Filed Dec. 19, 1932 3 Sheets-Sheet 5 INVENTORS Jbivn H. Odnbacir E; V BYJo71n Calianach ATTORKJEY Patented Oct. 29, 1935 UNITED STATES PATENT OFFICE BOAT Application December 19, 1932, Serial No. 647,874 Renewed September 21, 1934 8 Claims. (Cl. 114-79) This invention relates to a boat, more particularly of the freight-carrying character employed in canal and coastwise transportion, and it has for its object to afford a. structure that can be manufactured economically, and will afford a strong and rigid assembly that will stand any of the strains to which it is likely to be subjected.

A more particular object of the invention is to provide a construction that permits of constructing a hull entirely from metal in such a way that it can be fabricated quickly and with great resulting strength and rigidity.

A further purpose of the invention is to afford an arrangement that makes it possible to use a multiplicity of steel units arranged transversely of the boat in parallel relationship and which when welded together form the hull, each of said units being of integral formation and bent to a shape that determines the cross-sectional contour of the hull.

The invention has for an additional purpose to afford a structure that lends itself to an effectively reinforced and braced interior construction adapted to the carrying of stone, cement and similar heavy loads.

To these and other ends, the invention consists in the arrangement and construction of parts that will appear clearly from the following description when read in conjunction withthe accompanying drawings, the novel features being pointed out in the claims following the description. In the drawings: Fig. l is a side elevation of a boat constructed in accordance with a preferred embodiment of the invention; Fig. 2 is a sectional view on the line 2-2 of Fig. 1;

Fig. 3 is a sectional view on the line 3-3 of Fig. 2 with partsbroken away;

Fig. 4 is a sectional view on the line 4-4 of Fig. 2, and Fig. 5 is a. perspective view showing the relation of several of the hull-forming channel bars.

Referring more particularly to the drawings in which like reference characters referto the same parts throughout the several views, the hull comprises and is formed by a series of transversely arranged metal units preferably having the form of commercial channel bars, each of which is bent or preformed so as to afford a bottom portion and upwardly extendingside portions, or generally U-shaped from end to end. Each channel bar includes a web or body I and side flanges 2, the side flanges of adjacent channel bars being secured together by welding.

In fabricating and assembling the hull, it is preferable to weld together groups of channel bars to form transverse sections of the hull be- 6 fore placing them in the final assembled position, as in this way the channel bars may be welded while positioned horizontally and a stronger weld obtained than when positioned vertically. The groups of channel bars thus welded 10 are then'placed in the final position which they occupy in the finished assembly, and the adjacent faces of such sections are welded together.

The welded joint between sections, after they are placed in final position, will not be as secure It! as the other welded joints because of the dimculties attendant upon welding the final assembly, and to further strengthen the structure, reinforcing tie plates 3 are positioned over such welded joints and welded in position. Each of such tie plates 3 is slottedto extend around the adjacent flanges on opposite sides of the welded joint between the channel bars and thus serves to hold together more rigidly these adjacent flanges.

The completed hull assembly includes a multiplicity of integral channel bars, each extending down both sides and across the bottom of the hull, and secured by the welded joints between them. In order to further strengthen the hull construction and afford compartments in the interior, a series of bulkheads 4 are provided, each preferably consisting of an integral metal plate, and located at suitable intervals endwise of the hull and between flanges of adjacent channel bars. 4

Each bulkhead 4 is welded to the flanges of the channel bars contacting opposite sides of the bulkhead and affords an instrumentality for tying the hull together as well as constituting the ends of the different bins used for containing material to be transported.

Referring to Fig. 2, the bulkheads may be provided with openings 5 to permit passage endwise through the hull, and also to enable movement of materials therethrough on suitable conveyors. 6 designate keel plates located crosswise of the channel bars, and welded thereto and to the adjacent bulk heads between which the keel plate is positioned. Located on opposite sides of the keel plates 6 and parallel thereto are keelsons l similarly welded to the adjacent bulkheads and to the channel bars and extending somewhat above the keels 6 for a purpose that will appear presently, while 8 designate similarly arranged keelsons positioned between the keelsons 'l and of stone and similar material to be transported and these consist of inclined plates ill welded at their ends to the adjacent bulkheads, and also welded to the keelsons, Land 8 upon which they are supported, while at their upper ends, the

outer plates Iii are welded to the upper ends of the channel bars while the inner plates terminate in vertical portions H which are welded to the deck consisting of longitudinally arranged Welded channel bars l2. By arranging the deck channel bars longitudinally and welding them to the bulkheads, great strength and rigidity are obtained owing to the channel bars of the hull being at right angles to'the deck channel bars,

and the latter being transverse of the bulkheads.

Similar deck portions l3 are provided at the g5 sides while l4 designate vertical walls of the bins terminating in tops l5 which have suitable loading openings and covers it. The outlet at the bottom of each bin is closed by a cover I! which is removable to permit discharge from the bin when the material is to be unloaded into conveyors and removed from the boat.

As a further means for bracing and supporting the bins, angularly disposed bracing plates l8' may be employed, these being welded at their inner ends to the adjacent wall In of the bin and at their outer ends to the vertical portions of the channel bars.

In order to brace and strengthen the various keel plates, keelsons, and bin plates'these may 4 be provided with angle-bar bracing ribs designated at l9, that are welded to the faces of the plates in the angular positions indicated.

It will be understood that the hull sections comprised of the welded transverse channel bars are particularly adapted to form the amidship portion of the hull. The extreme bow and extreme stern portions of the hull, because of the required contour of these portions, may be constructed of suitable framing and plating in the well known manner;

It will be seen that in a boat thus constructed, each transverse unit or channel bar is an integral structure conforming from end to end'to'the transversecurvature of the hull of the boat, and 5 these can be fabricated and assembled much more quickly and with considerably greater economy than previously known methods of boat construction. The completed hull possesses excessive strength and rigidity that lends itself in 9 an ideal way to the transportation of stone, cement and similar heavy loads in canal and coastwise water transportation.

While the invention has been herein'disclosed with reference to a particular embodiment, it is not restricted to the details of construction or the arrangement described, but this application is intended to cover such departures or modifica- V tions as may come within the contemplated purposes of the improvement or the scope of the appended claims.
