NOSE FOR METALLIC VESSELS.

SPECIFICATION 'forming part of Letters Patent No. 358,971, dated March 8,1887.

Application filed September 7, 1886. Seri-.1l No. 212.S88. (No model.)

To all whom it may concern:

Beitknown that I, LBAcoN Foss, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have in- Venteda new and useful Improvement in Noses or Spouts forHollow Metallic Vessels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings7 Aforming a part of this specification,in explaining its nature.

The spouts or noses of hollow metallic vessels are of four general sorts. They are sometimes cast; but more usually they are made from sheet metal, and it is the latter sort of spouts to which this invention relates. Sometimes they are made of one piece of sheet metal rolled over a conical mandrel and seamed or soldered. Sometimes they are single-seamed above and below of two pieces of sheet metal, counterparts of each other; sometimes of two pieces not counterparts, but one of which forms the gutter or lower part of the nose, and the other the ceiling or upper part of the nose,and in this case they are seamed together1 along the upper outer edges of the gutter and ceiling, the edges ofthe upperpart being turned downward and inward upon themselves and the edges ol' the lower part, so as to make a single seam. I believe, also, that the conical nose in one piece has been double-seemed, with the projection formed by the double seam showing the joint outside. I do not, however, believe that any single-piece nose of sheet metal has ever been made with a concealed double seam, or with a double seam upon the inside, and certainly not one that was formed or ornamentally shaped after being put together.

My invention, briefly stated, consists in a sheetmetal nose having a double seam upon its upper surface and formed, after seaming, into a shape which on its lower side is convex from side to side and concave from end to end, and which is convex on its upper side from end to end and from side to side, and in which the gutter in the lower part of the nose is turned at a comparatively sharp angle into the cover which forms the upper part of the nose, and in the blank for making such a nose.

Figurel is the blank from which this nose is made. It is cut from one piece of metal, and

its different parts may be thus classified: The body of the nose within the broken and dotted lines y :c x x y and the continuous line y y is marked A. This will form the lower part of the nose. Fig. 4.) Vngs K K, Outside of the broken lines y form the top of the nose, which will be slightly crowned, as shown in Fig. et at H b H. The portions on each side of these wings K K, outside of the dotted lines x', which are to form the seaming portions at the top of the nose, are marked b c. A margin, d e f, borders all the lower edge of the nose in Fig. l, and lies outside of the dotted linesxxxxx. There are notches between the seam-forming portions b c and the flange-forming portions d e, and also notches between the iiange-forming portions d e and the flange-forming portion f.

The blank being thus prepared, the seamforming portions b and c are bent back along the line x x', the part Z) being bent toward the sur face which will form the interior of the nose when finished, and the part c being bent toward the surface which will form the exterior of the nose when finished. The flangeforming portions de f are bent toward the surface which will forni the exterior surface of the nose when finished along the line x :t xm x', and the wings K K are bent toward cach other along the lines x y, and the edges of the part A between the lines x y are bent together, so as to enable the seam-forming portions b and c, which have been bent into hooks, to be hooked together, substantially as shown in Fig. 3. This will make the wing K to which the seam-forming portion b is attached lie about three thick nesses of metal higher than the part Kto which the seam-forming portion c is attached, which would be unsightly, it being desirable to have the two sides form a practically continuous roof, as shown in Fig. 4 at H b H.

The completed nose is to have the general shape shown in Fig. 2-that is, with the wings K K practically continuous with each other, and the seam in the top apparently an abutting seam. The top of the nose should be slightly rounded over from side to side, and also slightly rounded from end to end, to be symmetrical. On the lower side it should also be rounded from side to side, as shown at G in (Represented in section at H G H of IOO Fig. 4, and somewhat concaved from end to end, as shown in perspective in Fig. 2. In order to accomplish this, when the hooks of the seam have been locked and the flanges turned, it is drawn upon a mandrel, such as is shown in Figs. 5, 6, and 7. This mandrel is of the general shape of the nose. It has a groove, I, .in its top, of about the proper depth and Width for holding the doubleseam. This groove is indicated by the dotted line w w of Fig. 5, by the groove I in section along the line g g of Fig. 5, which is delineated in Fig. 7 and in plan at I I in Fig. 6. The iianges el efare iiattened down true against the face of the standard L of this mandrel, or iu any other usual and proper Way.

The metal of the nose itself is formed to the shape of the mandrel by drawing it on, hammering, fulling, stretching, or the like, as is usual in Working sheet metal.

It is obvious that the flange-forming portions d ef may be omitted, and the margin Where the nose is to bejoined to the body be so cut as to make a butting-sealn with the body of the vessel, though this would be an inferior construction; yet it might be practical if a buttress or bolster Were formed at the junction of the body of the vessel With the nose; and it is also obvious that instead of the parts d e f being iianged regularly along the line x 5v o@ x x', they could be gradually instead of sharply bent out; but either of these constructions Would embody the main part of this inventionnamely, the single-piece double-seam nose with the double seam concealed by driving it into the interior of the nose in the last part of the process of forming up the nose.

I claim as myinvention and desire to secure by Letters Patent of the United Statesl. The blank for a one-piece sheet-metal nose, consisting of the bottom-forming portion A, the top-forming portions K K, the seamforming portions b c, and the ange-forming portions d e f, substantially as described.

2. A single-piece sheet-metal nose doubleseained ou the interior of its upper surface, and which has the bottom-forming portion A, the top-forming portions K K, and the seaining portions b c, and which is curved from end to end and from side to side, substantially as described.
