TRISTRAM D. BROWFN, OF CLIFTON SPRINGS, NEWV YORK.

ANTI-RUST VESSEL.

SPECIFICATION forming part of Letters Patent No. 469,991, dated March 1, 1892.

Application filed November 23, 1891. Serial No. 412,847. (No model.)

sel remains in a fairly good and serviceable condition. To provide against this premature rusting away of these parts of spout-vessels is the main object in producing the invention herein shown and set forth, the same being hereinafter fully described, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of a tea-kettle, showing my invention, the parts at the base of the spout being vertically and centrally sectioned. Fig. 2 is a plan of a portion of the tea-kettle, a part being horizontally sectioned, as on the dotted line 2 2 in Fig. 1. Figs. 3 and 4 are inside views at the base of the spout, the first having the spout omitted and the other showing the spout in place partly broken away at its base. Fig. 5 is an enlarged cross-section of a vertical joint or seam, showing another method of forming the same.

Referring to the parts shown, A is the body of a tin vessel, as a tea-kettle, for instance, and Bthe spout, which parts are substantially of the usual construction. The spout is preferably formed with an outwardlyturned flange Ct at its base and is passed outward through an opening I) in the side of the vessel, the flange resting against the inner surface of the latter.

0 is a sheet of zinc on the inside of the vessel, surrounding the base of the spout, as shown in Fig. 4. The Zinc sheet is formed with an opening g through it similar to the opening I) in the side of the vessel, but slightly larger, as shown in Fig. 3, the edge of the opening g being parallel with the edge of the opening 1). Thus constructed a narrow band d of the tin side of the vessel is exposed to view around the opening I) when viewed from within.

As constructed the periphery of the flange a of the spout comes within the edge of the hole 9 in the zinc and may or may not come in contact with the zinc, as is found most desirable and convenient in the matter of manufacturing the ware. In either case the flange of the spout is soldered securely both to the inner surface of the side of the vessel and to the sheet of zinc, the solder flowing through the joint 2', Fig. 4:, to the side of the vessel. The spout is likewise soldered to the vessel on the exterior of the latter. Thus formed the combination of the parts not only constitutes an anti-rust construction for the base of the spout and contiguous parts of the vessel, but gives the spout a much stronger hold upon the vessel on account of its being rigidly held by two plates instead of one-that is to say, the outer sheet of tin and inner contiguous sheet of zinc. The vertical edges of the zinc sheet are preferably held in vertical seams e in the tin, one on either side of the spout. I prefer to construct the parts in such a manner that the inner surface of the zinc shall be substantially even with the inner surface of the tin at either side of the zinc, as shown, the joints at the edges of the zinc being closely filled by solder h, Fig. 5. The edges of the zinc may be bent outward to enter the seams, as shown in Fig. 5, all the parts being firmly hammered down together, or these edges may be made straight and formed to substantially abut against the inner folds of the tin, as shown in Fig. 2. However, I prefer the former construction shown in Fig. 5. In the construction shown in Fig. 2 the seams are less prominent on the outside of the vessel on account of there being one less thickness of metal in each.

Usually in constructing this ware I depress the tin around the openingb, forming a peripheral recess f on the inside of the vessel, in which the flange of the spout rests when the parts are put together. At its lower end the zinc sheet is in contact with and soldered to the bottom plate 0 of the vessel, While at its upper end it is in contact with the top D at the joint between the latter and the circular side or hoop of the vessel.

The construction of the parts herewith shown is of course as well adapted to other tin vessels formed with spouts as to a tea-ket- New 5 formed with a hole in the side to receive the spout, and a sheet of zinc resting against the inner surface of the side of the vessel at the base of the spout, formed with a hole similar to and opposite the said hole in the vessel, the

[O zinc and the tin at the base of the spout being soldered together and to the spout, sub stantially as shown and described.

2. A tin anti-rust vessel having a spout and formed with a hole in the side to receive the 15 spout, and a sheet of zinc resting against the inner surface of the side of the vessel at the base of the spout, formed with a hole similar to and opposite the said hole in the vessel, but larger in dimensions, the spout being formed with an outwardly turned flange resting against the inner surface of the tin and having the outer edge of the flange within the inner edge of the zinc, the parts being soldered together substantially as shown and described.

In witness whereof I have hereunto set my hand, this 19th day of November, 1891, in the presence of two subscribing witnesses.
