Application filed .Tuly 25,

To all er1/0m t may concern.'

Be it known that I, FRANK SWEET a citizen of the United States,`residing at uifalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Metal Boats, of which the following is a sepcification.

This invention relates to improvements in boats, launches, tugs or the like, which are made of metal.

The objects of this invention are to produce a boat of this kind constructed of corrugated metal secured to metal ribs in such a manner as to produce a strong and durable construction; also to so construct the boat that the lower edge portions thereof will `be more durable and will not cause the boat to leak if these edge portions are chafed through; also to provide the boat with a bow plate or nose piece of improved construction; also to provide the boat with removal metal seats; also to improve the construction of devices of this kind in other respects hereinafter specified.

In the accompanaying drawings Figure l is a side elevation of a metal boat embodying the invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is a fragmentary, longitudinal, sectional elevation thereof on an enlarged scale on line 3 8, Fig. 2.

Fig. 4 is a fragmentary, transverse, sectional elevation thereof on line 4 4, Fig. l.

Fig. 5 is a rear elevation thereof.

Fig. 6 is a transverse sectional elevation thereof on line 6 6, Fig. 2.

Fig. 7 is a fragmentary, longitudinal, sectional elevation on `a still larger scale on line 7 7, Fig. 5.

Fig. 8 is a fragmentary, sectional, plan view thereof on line 8 8, Fig. l. Y

The boat shown in the accompanying drawings is of the flat bottom type but it will be understood that the invention is not limited to this type of boat since a roundbottomed boat may embody the features of the invention.

The boat includes abottom A, sides B and a stern C, all of which are made of corrugated sheet metal, the corrugations at the bottom and sides of the boat extending lengthwise of the boat so as to afford very little resistance to the movement of the boat through the water and so as to strengthen METAL Bohr.

theboat lengthwise. Thek corrugated metal 1s secured to the framework of the boat, which in the construction shown is made of angle irons but. which may be made of channel beams or members of other sectional shape and which includes two lower angles or longitudinal frame members D, and upper anglesY or `longitudinal frame members E, the upper and lower longitudinal frame members being bent to conform to the shape ofthe boat and preferably meet at a point at the bow of the boat. The lower longitudinal members D are connected at intervals by means ofvtransverse members F and the upper and lower longitudinal members are connected by means of ribs or upright frame members Gr. The corrugated metal is riveted or otherwise suitably secured to the longitudinal., transverse and upright frame members, the rivets being arranged in the parts` of the corrugations touching the framey members. v

The lower edges of the boat are preferably formed by bending the bottom plate A upwardly to overlap the side plates, and the edges of both plates are secured to the upwardly extending flanges of the angle `irons D, the lower edges of the side plates eX- tending beneath the bottom in the form ofv hooks. The bottom A is also preferably secured to the lower flangesof the lower longitudinal members, the upwardly extending portions of the bottom plate being bulged downwardly and outwardly from the angle irons D and overlying the hooked portions of the sides B, thereby forming the rounded edges H. The connections between the bottom and side plates and the angles D are` preferably made by means of rivets .7L and the bottoni and side plates are preferably also welded to the angles D throughout their length in such a manner as to form a watertight jointV between the bottom and side plates and the lower` longitudinal members. The rounded edges H formed at the meeting of the sides and bottoni plates form skids or slides of double thickness of metal for the boat when the same is out of water. By welding the side and bottom plates to the lower longitudinal members D, a water-tight joint'is formed between the angles and the plates so that the wearing out or chaiing through of the portions H of the plates does not cause leaking of the boat and the provvision of this joint together with the skids Vprovided with a plate I bent substantially into if-shape and covering the front ends'oii the side plates. The edges of the plate I are preferably bent sov as to fit within the lcorrugations of the side plates of the boat and are welded to the side plates, thus forming a water-tight connection and also reinforcing tliebow of the boat. Y

The vstern G of the boat is preferably rugations of which are arranged vertically. rEhe joints .or seams between the bottom plate, stern plat-eend side plates are preferably welded so as to'form a rigid and secure structure and to forni Vwater-tight seams. At the bow and the stern the boat is partly decked over by means of corrugate'dpieces K and I which are secured to deck beams s respectively, the deck beams connecting the upper longitudinal iframe members E and reinforcing the same.

rlhe seats may be arranged in the boat in any desired manner. In the construction shown the seats are made removable land each seat comprises a metal plate L which, it desired, may also be oit corrugated metal and'which is secured at one side to a beam Z which is secured at its opposite ends to upright frame members G, preferably'by` means of bolts which permit the beam Z and plate L connected thereto to be removed Vfrom thc boat. rllie plates L are supported in their operative positions by means of cleats or the like Z, which iny the construction shown arein the shape of'V angle beams secured tothe Vcorrugated side plates B of' V*the boat and on which the ends of. the seats rest. The beams Z of the seats also act asa reinforcement of the iframe ofl the boat,

'I he structure described has the advantage that the corrugations of the side and bottom plates reinforce the trame so that only four longitudinal ,traine members are needed for a boat of considerable size. By Vusing corrugated metal, the; plates may be thinner, since the corrugations increase theV strength thereof and resist denting or otherwise de Jforming the plates. rThe' manneroi joining the 'edges and side plates of the Vboat insures a water-tight construction, requiring no calking and prevents leaks even when the vmetal oit the portions I-I is worn through.

made by means ci a piece of metal, the corior the upright members G Ey making the seats removable, the interior arrangement of the boat may be. readily i changed to suit the user;

I claim as my invention:

l. In a metal boat the combination ot' a ufJame including upper and lower longitudinal members, and side plates and bottom plates extending throughout the length of the lboat and madeV of corrugated metal arranged with the corrugations extending lengthwise of the boat, thelowcr edges of the sideplates Aand the outer edges ofthe bottom plate being bent outwardly and overlapping and oriningskids ot a double thickness of metal and being welded to said lower,

longitudinal members at opposite sidesv of said skids whereby thewearing' out of said skids will not cause leaking.

2. In a metal boat,'the combination of a frame including lower. longitudinal members consisting'of angle irons, and side platesV and bottom plates extending substantially throughoutthe length ot the Vboat and having corrugations extending lengthwise ot the boat, the lower edges or the side plates extending beneath the bottom in the form of hooks, the sideY edges o' said bottom plate projecting downwardly, outwardly and upwai'dly from' said lowerlongitudinal meinbers Vand overlapping the hooked portions of saidV side plates, said bottom plate being welded to the horizontal side oi" the angle iron and said side plates beingwelded tothe vertical side of said angle'l iron, thereby i `forming skids between said welded connections.

3. In a metal boat, the combination of a trame, side plates having coriugations eX- tending lengthwise of the boat and meeting at the bow or' the boat, Va'bow plate bent into sjibstantially V-shape and connecting the ends oi said sidezplates at the bow, the edges of said bow plate being bent to coniormto said coriugations of the side plates and being secured to said side plates-toy form a water-tight connection therewith, and a stern plate to which the rear ends or" said 'side Vplates are connected, said bow and stern plates being iittedvto the corrugated side It.
