T0 ALL WHOM IT MAY CONCERN: n

Be it known that I, MAxrMrLLiN Werrrcu, oi Sacramento, in the county of Sacramento, and State of California, have invented certain new and useful Improvements in Metallic Barrels, Torpedoes, and other Vessels, for insuring great strength, durability, und impcrviousness; und I do hereby declare the following to be a. clear and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which like letters indicate the same purts,\and in which drawingsl Figure 1 represents a side view of my improved bnrrel with the rolling bolt around it.

Figure 2, an end view'oi' the same.

Figure 3, o longitudinal section of the improved barrel.

Figure 4, a cross-section of the same. Y

Figure 5 represents a corrugated barrel with my improved joint.

Figure 6 represents in sections various modifications of my improved plan 'of formingjoints of metallic barrels, &c. Y

The object of my invention is to obtain a metallic barrel or otberivessel which will possess great strength, though made oi' comparatively thin metal, and at the sa'me time be proof against yleakage or wastuge. My invention eonsists'in making the joints, which are to be secured by means of rivets or bolts, and soldered or brazed together, proof against the passage-of moisture or even of gaseous iuidsf For this purpose I provide one or more grooves or recesses so located as not to be in line with the rivets. These recesses are to he ofterwards filled with metal or alloy, which must he softer than the metal of which the barrel is formed. i It thus forms packing rings or packing pieces in grooves in which they are secured either by being soldered or by upsetting or by doubling the edge of tho sheet metal so as to confine the packing, or by some other equivalent method. If necessary the soft metallic packing may he driven into the groo'vcs the more completely and perfcctlylto tighten the joint und render it impervious. I

'1 0 enable others skilled in the art to make and use my improvement, I will now proceed'todescribe it in detail.-l

i Ir. the'drawing, U, fig. 1, regresents the metallic barrel, the convex shell of which is made of sheet iron, which can he formed from a straight sheet by passing it through a. set of properly formed rollers. The curved sheet is then passed through a set of rollers arranged in such a manner as tobend the sheet iinto a circular barrel, which can best be done while th'e metal is in a warm state. It maybe formed cylindrical or witha bilge and either plain or corrugated. The `sheet iron may be rolled thicker at its outeredges for the chine, or thicker in the middle for the bilge, or in any other form that may be desired. When the barrel is thus rolled ont its edges are trued" up and the-recess groove is made by stumps, diem-rollers, or otherwise, not for from the rivet holes, as shown at e in the drawings. The barrel-heads C are hanged, and on the flange e the recess groove is made for'the reception of the packing 7' of the joint z. Thehead is fitted in the chine and the hoop' dis properly punched and fixed upon the chine, and the parts are duly riveted together. Thus a very strong joint is made. A head cross-piece, g, may he fitted in the flange c to the outside of the head G. It will serve to give stability to the head, and protect the chine and joints ol' the barrel ehdwise. The ends of this crosspiece g muy be bent, as shown in fig, 3, so ns to form a strong seat or hold for the hoisting hooks.' The rivet joint x and the recess groove e are rendered impervious by lling up the recess e with a soft metal composition or alloy, forming thus a substantial packing for the joint z. The recess groove e may be filled by ponrig the molten metal, by putting the metal on with a soldering-iron or by heating the joint und then dipping it in the molten metal. 'In iig. (i some of the different shapes and modifications of the recess groove e are shown. All

the joints are riveted or bolted securely together, and thc recess groove made so as not to be in line with the rivets, arid these joints are riveted before the recesses are filled withthe soft metal packings, which are secured therein by soldering o'r hy the form of the grooves. In each of these cases itwill be seen that the rivets pass through all the iron parts forming the joint and hold them all firmly together. The recess grooves are formed on one side or on hoth'sides oi the rivets, so that the soft metal may be inserted after the parts are iirmlyriveted together. 'lhe bung-block u is riveted to the inside of the barrel, and is made impervious in the same manner as the other joints. It may be provided with a screw-thread -to receive the tight-itting 5crewbung w. Thev faucet-blockfis made impervious hy having also u-reccss groove joint similarly arranged, and provided as that o`i` the bung-block n. The hung and faucet-blocks may be secured at any desired place in the barrel. According to the size and strength required of the vessel'orv barrel, the j oints are secured by single or double rows of rivets, andare provided With recess grooves e, or with a series of recess grooves so located as not to bc in line with the rivets, and are rendered impervious by corresponding soft metal packing pieces or rings r in the recess grooves e, as hereinbefore described. Instead of rivets, screw-bolts may be used for fastening the head C to they chine of the barrel, so as to enable the head to be removed with little difficulty for the convenience of loading return'freights or for other purposes. When replaced they may be rendered impervious by a few blows applied to driving the soft metal packing more firmly into the grooves which contain it. Any accidental leak that may be caused by any other circumstance mayjn the same manner be remedied.v The .barrels'maydle made of any desired sheet metal, but it is most economical to make them of sheet iron, which muy be galvanized or otherwise coated wholly or partially with any metal, alloy, or composition that may seem best adapted to that purpose.` This can be best done after putting ono head into the barrel, and before inserting the other. This other head may then be coated and then bolted or riveted in the chine of the barrel.

I am aware thatjoints have been made by inserting a packing of soft metal, leather, or India rubber, or of other material between the two sheets ot' metal that are to be riveted together. I am also aware that Water pipcs of cast iron or other'material have been'connccted together by making one end of the pipes it into an enlarged end of the next one, and then filling the space withfmolten lead or other equivalent material. But it is clear that this last-named process would not be applicable to the manufacturing of barrels, tanks, or other similar *.vessels. t istalso evident that the insertion of a packing of soft metal, or of leather, India rubber, or other equivalent substance into the joint and under the rivet, is substantially diierent from my method of first riveting the parts firmly together, and theninserting the packing by means of a provision made for that purpose. What therefore I claim as new, and desire to secure by Letters Patent, i s l 'My improved mode of rendering impervious the joints made in`barrels, tanks, or other vessels which are constructed of sheet or plate metal, by the insertion o f a packing of soft inetal or alloy in grooves provided for that purpose, which are not in line with the rivets or bolts, and are so constructed and arranged that such packing may be inserted after the riveting has been completed, substantially as and for the purpose described.
