This simple contrivance consists in attaching to the enlarged neck or mouth of mineral water and other bottles, a metallic casting and screw cap piece, in such a manner as to readily enable a part or the whole of the effervescent liquid in the bottle to escape through a tube at the side of the casting, or to be closely confined in the same. In our engravings, Fig. 1 is a section of the improved faucet applied to the neck of a mineral water bottle, and Fig. 2 is a section of the same and the neck of the said bottle in an inclined position, with the cap partially unscrewen, to admit the escape of the liquid. The enlarged end of the tapering or trumpet-shaped tube, A, is inserted in the enlarged space, B, formed in the mouth or neck of the bottle, C. This enlarged space is also made in the form of a frustum of a cone, the neck of the bottle having a shoulder at this part, to admit of its inner enlargement, in which latter it is secured, with its edge resting on the shoulder, D, in the neck of the bottle, formed by the space, by any suitable cement poured into the space, B, ber.wenn the lower portion of the periphery of the tube, A, and the periphery of the said space. A cylindrical tube, E, is CRSt or otherwise attached to the tube, A, and extends upward from its periphery to within an' eighth of an inch, more or less, of the top edge of the inner tube, A, so as to have a concelltric space between the two tubes, A E, which has an outlet through a tube, F, secured to the side of the outer tube, E. On the upper end of the cylindrical tube, E, is screwed a cap, G, having an elastic or leather washer secured to its inner flat surface, and a serrated fLmge formed on its sides, for enabling it to be turned between the forefinger Rnd thumb, to either scre,w the leather washer firmly upon the upper edge of the iuner tapering tube, A, or to unscrew and raise the same therefrom, and open a passage-way between said upper edge and the cap, to allow the escape of the effervescent liquid from the bottle. When the bottle is turned to the position represented in Fig. 2, with the tube, F, over the tumbler or other vessel into which the effervescent liquid is to be discharged, the cap, G, can be unscrewed, to admit the required quantity to flow over the edge of the inner tube, A, through the space between the two tubes, A E, and in the event of any of the liquid still remaining in the bottle, the cap can be again screwed tightly upon the edge of the tube, A, so as to effectually stopple the bottle, and keep its contents free from the exterior air. This characteristic is peculiarly desirable in beer bottles, as through it a glass, or a portion of a glass of the liquid can be drawn, and the atmosphere readily ex- eluded from the portion remaining in the bottIe, so as to prevent the evaporation of its effervescent properties, and its deterioration by the contact of the air. The saving of corks effected by this permanent stopple would, it is supposed, pay for it in three to four months. The patent for this novel bottle faucet was issued on the 6th of July, 1858. Any further information can be obtained by addressing the patentee, M. C. Cronk, Auburn, N. Y., or S. D. & J. K. Wackman, who are half owners of the patent. RAILROAD AT CAPE TOWN—The government of the cape of Good Hope have advertised for tenders for constructing a railroad from Cape Town to Wellington—a distance of fifty-one miles. They estimate the cost at about two and a-half million dollars.
