lTO ALL WHOM-I'I MAY CONCERN Be it known that I, FRANcIs .MonANDn of Malden, in the county of Middlesex, and State of Massachusetts, have invented anew and useful Improvement in Cooking-Apparatus; and I do hereby declare the following to be a full and correct descrip in which-'- l v Figure 1 is a vertical central section of the apparatus. p

The nature of this improvementconsists in providing the boiler and steaniingvessels or a cooking-apparatus with waterjoints and return-tubes, for the purpose of diminishing the escape of steam and odor from the apparatus, and securing the return of the water of condensation to the boiler without passing through or among the articles to be cooked, all as hereinafter more fullyrsct forth.

In the drawing, A marks the boiler, which is intended to rest upon an ordinary cooking-stove, and may have a shoulder to enter the holes of the stove. 'B and Q are the stearnirig-compartments, which have perforated bottoms, b c, for thcupward passage of steam. D is the lid or covcr.- Around the upper edge of boiler A runs a trough, E, intowhieh dips a lip, e, prcecting from the bottom of vsteaming-vessel B. A similar trough, F, around the top' of vessel B, receives a similar lip, project-ing from the bottom of the vessel' C; .and a like troughs G, 0n SCMDCIEC, receives the lip d of the cover D, as shown. From near the tcp-0f trough E, a lreturntube, H, descends and enters the boiler, A near the bottom. A similar tube, I, leads from trongluF into the steaming-vessel B, and a like tube, J, from trough Gr into vessel C. A-n escape-pipe, K, covered by a removable cap, L, projects from the top of the cover D, as shown, and serves to carry olf an excess of steam, which may be led into the` stove-funnel o r chimney. I

The troughs E F G may, if, preferred, be placed on the inside ofthe several vessels to which they belong, but I find that theyoperate better on the outside. v 1 Y The operation is as follows: Water is placed in the boiler A, and the articles to be cooked are placed in the steaming-vessels B and C. One or both may be used,- as preferred. The troughs E F G are partially filled with water, so as to form, with the lips a, CZ, and e, water-joints between the several vessels, and between the upper vessel and thelid. When thewater in A boils, the steam rises through the perforated bottoms I; c, is diffused among the articles in the vessels B C, and seeks an exit through the joints betweenthe vessels; but, coming in contact with the water in'the troughs E F Gr, it is immediately condensed. When the' water in these troughs is tion of the same, reference being had to the accompanying* drawings,

' thus increased, by the addition of the condensed steam, it overilows through the tubes H I J, and, isreturned to the boiler A'either directly, as through I-I, or by running down the sides ofthe vessels B C. Thus a supply vof fresh steam is continually passing upward, during the operation, through and among the articlesto be cooked,

while the Water of condensation returns to the boiler without passing among those articles, from which it results that there is no communication of flavor from one article to another, however dissimilar they may be in kind;

through the pipe K, which may lead to the funnelor the chimney. Y

Having thus fully described my improvements,'what Irclaim,- anddesire to secure byLettcrs Patent, is- Providing a compound steam-cooking apparatus, such as described, with water-joints and return-titties, substantially in the manner and' for the purpose specified'.

The above specification of my said invention, signed and witnessed at Boston, this rst day of February, A. D. 1868. i

and however rank or. pungent their savor. Y If the supply of steam is excessive, it may be allowed to escape FRANCIS MoRANnr.
