Specification of Letters Patent.

. Patented Jana l5, lltltlfia Application filed May 21, 1914:. Serial No. 839,973.

To all whom it may concern:

Be it known that I, JOHN L. TAYLOR, a citizen of the United States, residing at Oakniont, in the county of Allegheny and State of Pennsylvania-, have invented a new and useful Meta-l Barge Construction, of which the following is a specification.

My invention relates to the construction of barges, boats, pontoons or other open or decked floating craft, used in passenger traffic or for conveying cattle or in handling and conveying merchandise, coal, sand and like materials or products, both packaged and in bulk.

Heretofore such vessels have been generally formed of wood. In the few cases where metal has been used the flat plates employed in forming the sides and bottom necewitate the use of a large-number of stizdeners. The use of such a large number of stifieners not only adds to the weight and decreases the carrying capacity of the craft but, 0n account of the short distance between the sti-fi'eners seriously interferes with the unloading operations in removing bulk cargoes, in which cases a grab bucket e is employed.

a barge framed in the usual manner with wooden dunnage, 1t is necessary to reso move the dunnage several times during the till life of the barge, at periods varying from four to seven years, and, at intervals not exceedmg two years, it becomes necessary to remove the dunnage in order to clean --and,

paint the barge bottom.

- In a metal barge, having a wooden dunnage and engaged in carrying cargoes such as coal or sand,.all or part of which is finely divided enough to drop between the cracks, which are formed by the alternate wetting and drying of the dunnage, the space between the bottom plating and the dunnage soon becomes filled, and results in a serious loss in cargo carrying capacity.

One object of my 1nvention is to provide a barge or similar floating craft framed of metal andhaving novel means whereby the necessary stifi'ness and strength is obtained with a material reduction in dead weight and. consequent increased carrying capacit on a given draft or with a reduction in draft in carrying a given weight.

Another object of the invention is to provide a metal barge construction having improved means by which the number of frames used in the barges is lessened to a large eXte t and the use of the grab buckets ordinarily employed in removing-bulk cargoes thereby greatly facilitated.

A further object of this invention is to 2 provide a barge in which the necessary number of punched holes in the plating and number of rivets used in fabricating the craft are reduced to a large extent, leakage and liability of leakage is lessened, the cost of upkeep is reduced and the life of the craft is lengthened.

it still further object of my invention is to provide a barge having novel means for strengthening the barge framing, lessening the liability of sinking of the barges and facilitating the raising of sunken loaded barges.

Another object of my invention is to provide a. barge construction whereby the num ber of necessary bottom stiffening members is greatly reduced, liability of engagement of the stiffening members by grab buckets employed in unloading operations is avoided and consequent injury or damage to the barge thereby overcome and prevented.

it further object of my invention is the provision of an open barge having a bottom constructed in such manner that the cargo can be loaded directly upon the bottom plating, the necessity of the wooden dunnage usually employed in a steel barge of ordinary construction is avoided and tile dead weight is thereby decreased with a. corresponding increase in the cargo carrying capacity.

A still further object of the invention is to provide a barge, the cargo of which canill llll

In the accompanying drawings, referring to Figs. 1', 2, 3 and 4 a barge having vertical sides 2 and rake ends 3 formed of fiat plates and a bottom 4 formed of corrugated plates is shown. Plating is provided at each end of the barge, which extends horizontally inward to form a deck 5 and which is joined to an inclined plating wall 6 so, as to form a water tight bulkhead or compartment 7 in each end of the barge. The plates forming the rake ends of the barge are connected at their upper edges to a steel corner casting 8, this casting being riveted at its ends to the plating forming the sides 22 of the barge.

The barge bottom 4 is formed of a series A barge form water tight compartments 14 of triangular cross section, the bottom of the barge forming one side of the so formed triangle.

In constructing the transverses 12 (see Fig. 4) so as to form a water tight compartment, a rolled steel angle 15 extends lengthwise from one side to the other of the barge at the apex of the transverses and forms a convenient means for connecting the adjoining upper edges of the plates 13-13 forming the inclined sides of the transverses. Angles 1616 also are employed at lntervals in the length of theplates 13 to form stilfeners for the inclined sides of the transverses, the upper ends of these angles being connected together by gusset plates 17 Angles 18 are riveted to the lower edge of the side plates 13 and to the bottom plates 4, one flange of these angles being 'bent to the same shape as the corrugated bot-tom plates to form an'air and water tight ]01Ilt 1 J owed by its lower edge to the upper ed e or apex of each transverse 12 at each si de of the barge is a plate 19 forming a-knee which-is fastened to the side of the barge by means of an angle 20. Stiflening angles 21 are setween the end transverses and the ends of the barge is a series of side stiffener-s 2222' of each side of the barge is a metal channel 24 having its flanges turned downward as shown, the channels being riveted by one flange to the sides 2 of the barge. The up: per ends of the knees formed by the plates 19 and angles 20-21 are fastened to the channels 24 and also the upper ends of the stifleners 22 and the lower ends of the stifl'eners 22 are secured to the bottom plating by means of angles or bent plates 25. Secured on top of each of the channels 24 and also on the upper edge'of the castings 8 on the ends of the barge is wooden planking 26 forming the gunwales of the barge.

In the sides of each of the hollow transverses 12 is a manhole having a water tight man-hole cover 27 and the horizontal plating forming the decks 5 at each end of the barge is provided with a man-hole and manhole cover 28.

The barge is provided with the usual com- I the towing lines also are fastened to these bitts, when the barge is being towedfrom place to place.

In the construction shown in Figs. 5, 6, 7 and 8 of the drawings the sides 2, and rake ends 3 are formed of flat plates and the bottom plating 4 is corrugated, the bottom plating having flat portions 9 and 10 connected by inclined portions 11 formed in the same manner as in Figs. 1, 2, 3 and 4. Se cured on.each end of the transverses 31, which are formed of rolled I-beams, are knees 32 formed of a web plate and angles 33, 34 and 35. Each end of the barge is pro vided with a horizontal deck 5 and sloping plating wall 6 which serve to form a water and air tight compartment 7 in each end of the barge, and in this case diagonal bracing formed of angles 36 "is' also provided to stifi'en the rake ends 3 and deck plating 5 and plating 6. On each side of the barge, between the transverses 31 and also between the end transverses 31and ends ofthe barge, are Vertically extending channels 37 secured by one flange to the side plating 2 to stiffen the sides of the barge. The channels 24 and Wooden planking 26 extending along the upper edge of the barge sides forms the gunwales of the barge and the upper ends of the knees 32 are fastened to the channels 24 as in Figs. 1, 2, 3 and 4. Towing bitts 29 and 30 are secured to the gunwales of the barge and a man-hole having a cover 28 is formed in each of the decks 5. The lower edge of the sides 2 are connected by knuckles 23 formed of angles to the edges of the corrugated bottom plating 40f the barge, the

angles 23, as shown, being placed outside of the side and bottom plating.

In the construction of Figs. 9 and 10 the barge has corrugated plating forming the sides 2 as well as the bottom plating 4 of the barge. The rake ends may be formed either of corrugated or flat plates as is desired. Transverses 38 formed of I-bea-ms and knees 32 formed in the same manner as in Fig. 7 are fastened to the bottom and the side plating in the manner which has been described and channels 24 with downwardly turned flanges are fastened to the side plating 2 and to the top of the knees 32. In this construction no vertically extending angle stiflenersare employed, the corrugated side plating having suflicient stiffness in itself and diagonally extending angles 40 (see Fig.

10) fastened to the corrugated side plating 2 between the transverses 38 are provided to itJake the shearing strain on the sides 2 of the arge.

In Figs. 11 and 12 a decked barge is shown. In this construction the barge has flat side plating 2 and corrugated bottom plating 4, a round knuckle 41 being employed to connect the lower edge of the side platingwith the adjacent edge of the corrugated bottom plating.

Transverses formed of channels 42 are employed at intervals in the length of the barge, these transverses being secured by one flange to the corrugated bottom plating 4. 4. plate .43 and stifl'ener angles 44 and 45 are used at the sides 2 of the barge to connect the ends of the transverses 42 and side platlng 2.

At the upper ends of the vertical stiffene-rs formed by the plates 43 and angles44.

45 a channel 46 is secured which extends from side to'side of the barge, this channel being bent to the same curvature as the deck of the barge which is formed of flat metal plates 47. A series of channels 48 which rest on the upper flange of the curved chan nel and the transverses (as is shown on the left hand half of Fig. lll. the barge and at suitable intervals in the length of this barge, a'bulkhead is formed of fiat plates, which (as shown on the right hand half of Fig. 11), extends from the deck plating 47 downwardly to the bottom plating and from side to side of the barge so as to form water tight compartments at intervals in the length of the barge. The bottom angles 53 are bent to the contour of the corrugated bottom plating so as to form. a tight joint. Vertical stifieners formed of angles 54 are used to stifi'en the bulkhead.

length of the barge. Angles 58 .(see Fig.

15) forming the square knuckles used in this construction are employed to connect the adjacent marginal side edges'of the plating forming the sides 2 and bottom 4, these angles extending u the rake ends 3 to the upper marginal e ges or gunwales of the barge. As shown, the corrugations 57 in the bottom plating'decrease in depth toward the top edge of the rake ends of the barge although obviously the same result is obtainable by continuing the corrugations at a universes 60 which, in the construction of Figs.

form depth around and up the rake ends 3 of the barge. An angle 59 is secured by one leg to the. upper edge of the rake end plat- 1ng, the other'leg thereof being riveted to the plating forming the decks 5 at the ends of the barge. as is shown in Figs. 13 and 14. Located within the barge at suitable intervals in the length thereof are the trans- 13., 14, 15 and 16 are H-shaped in cross section, being-built up (as shown in detail in Fig. 16) of angles 61 riveted on opposite sides of each of the marginal edges of a central connecting web member '62. Wooden fillers 63 are placed in the spaces between the angles 61 on each side of the web 62 so as to prevent the grab-bucketsused in unloading the barges from catching or grasping the transverses and in this way possible damage to the barge is avoided and overcome.

The vertical stifi'eners or uprights on the transverses 60 are formed of channels 64 placed back to back with a gusset plate there- At each end of between forming a knee 65 by which the vertical members are secured to the ends of the horizontally extending bottom members of the transverses 60. Angles 66 are fastened by one leg to the channels 64 at the ends thereof, the other leg of these angles being riveted directly to the plating forming the sides2 of the barge.

The upper ends of the channels 64 are fastened to the channels 24 forming the gunwale on each side ofthe barge, one flange of these channels being riveted to the side platthe decks 5 so as to afl'ord means for securing the marginal side edges of the deck plating to the upper edges of the side plating 2 of the barge. Angles 68 on the inclined. edge of the knee 65 serve to stiffen the plate forming this knee.

The intermediate vertical side stifi'eners are formed of short pieces of angles or bent plates 69, one leg of these angles bein fastened to the plating 2 forming the arge sides, the other leg being riveted to the angles 7 0 extending continuously from the top to the bottom of the barge sides 2.

The Z-bars which extend horizontally at intervals in the height of the barge to form the side stilfeners 71 are secured by one leg to the plating forming the sides 2, and the Z-bars are fastened by one leg to the vertical members 64 of the transverses 60 and to the angles forming part of the intermediate side stifi'eners 69 at the points of intersection therewith soas to strengthen the flat sides of the barge between the transverses 60 and vertical intermediate side stifl'eners 69.-

Man-holes in the decks 5 at the ends of the barge provide means of access to the compartments 7 and, when the covers 28 are secured in position in the man-holes, an air and water tight compartment 7 is formed in each end of the barge when the partition or wall 85 is extended to the bottom of the barge as before described.

The use of the transverses at such widely separated intervals in the length of the barge is accomplished and made possible by reason of the very stiff and strong construction obtained in the use of corrugated metal plating in constructing the barge bottoms as shown in Fig. 15 or the sides and bottoms of the barges as in Figs. 17 18 and 19.

In Figs. 17 18 and 19 a modified form of ing 2. The channels forming the gunwales I are extended beneath the plating forming rounded knuckle or a separate plate forming the knuckle 80 may be used to which the abutting ends of the side and end plating are riveted (in the manner shown in Fig. 17). The corrugated bottom platin is continued around the rake ends 3, pre erably in the same manner as shown in Fig. 14.

The transverses 74 in Figs. 17 and 18 are of modified construction, being formed of plates bent into the shape of inverted U ith angles 75 riveted by one leg to the marginal edges of the said shaped plates. The

outstanding legs of the angles 7 are utilized in riveting the corrugated bottom plating t of the barge to the transverses 74. At each end of the transverses, a vertical member 76 is provided, also formed of a plate bent into U shape and having one leg of an angle 77 riveted to each marginal side edge of the U- shaped plate, the other leg of these angles being in direct contact with and riveted to the corrugated side plating 2.

In this construction the horizontal side sti'fi'eners used in the construction of Figs. 18, 14: and are dispensed with and the intermediate vertically extending side stifieners of the preceding figures are also omitted. Plates 7 8 secured to the vertical members 7 6 and the ends of the horizontal members forming the transverses 74: afi'ord means for bracing and fastening these vertical members to the transverses of Fig. 17, and bent plates 7 9 are employed to connect the ends of the transverses to the rounded knuckles 80 of the barge. The plates 7 8 forming the knee are stiflened along their inclined marginal edge by angles 82. The upper ends of the vertical members 76 in this construction are connected to and support the channel beams 24 secured by one flange to the top marginal edge of the side plates in forming the gunwales, in the same manner as heretofore described. Wlth some constructions made in accordance with this invention, such as for example that shown in Fig. 17 in which the plates forming the sides of the barge are corrugated, the number of intermediate side stifieners'may be materially reduced or in some cases may be entirely omitted.

The advantages of my invention will be apparent to those skilled in the art. Gorrugating the metal plating stifi'ens and strengthens the barge to an extent which permits the number of transverses used to be largely reduced. The omission of the large number of transverses and side stifieners made possible by corrugating the. barge plating greatly decreases the number' of rivet holes in the construction and to that degree lessens theamount of leakage or possible leakage. in the completed structure. The reduction in number of rivet holes and rivets and in the amount of riveting necessary also materially reduces the first cost of the fabricated structure.

By forming the bottom of the barge of corrugated metal plates, the wooden dunnage, usually employed, is made unnecessary, and the presence of projections on the bottom of the barge liable to be engaged by time in erecting, and the cost of making the barges is materially reduced; The construction of a metal barge having a corrugated bottom supplies the need for a light weight metal barge which is particularly adapted to the river carrying trade and Which can be provided at a cost approximating that of wooden barges.

Modifications in the construction and arrangement of the parts can be made without departing from my invention. The barges may have corrugated sides and bottom with a square knuckle instead of the rounded knuckle shown in Fig. 6. The transverses of Fig. 17 may be employed in forming the barges of the other figures. The intermeditill;

ate side stifieners and the horizontally extending stifieners may be employed or not,

as is desired. The water tight compart ments in the ends of the barge, and the hollow transverses forming water tight compartments at intervals in the length of the barge may be employed or not as is desired. The corrugations may be sinuous as shown in Figs. 15, 16, 17, 18 and 19 or may be formed in the manner shown in the other figures. The corrugations may be terminated short of the rake ends of the barges and other changes may be made within the scope of my invention as defined in the appended claims.

I claim 1. A barge or similar floating craft com prising sides, rake ends and a bottom formed of metal plates, a deck at each end of the barge, plating connected to the deck and bottom to form water tight compartments in the ends of the barge, and a series of cross frames or transverses between the ends of the barge, said transverses being hollow and being triangular in cross section with the barge bottom forming one side thereof, and formin water tight compartments.

2. A barge or similar floating craft comprising sides, rake ends and a bottom formed of metal plates, a deck at each end of thebarge, plating connected to the deck and bottom to form water tight compart ments in the ends of the barge, and a series of cross frames or transverses between the ends of the barge, at least one of said trans verses being hollow and being triangular in cross section With the barge bottom forming one side thereof and forming a Water tight compartment intermediate the ends ofthe barge.

3. A barge or similar floating craft comprising sides, rake ends and a bottom formed of metal plates, a deck at each end of the barge, plating connected to the deck and bottom to form water tight compartments .in the ends of the barge, anda series of cross frames or transverses between the ends 4 of the barge, at least one of said transverses set my hand.
