IMPROVEMENT IN COFFEE-POTS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, RICHARD H. Korma, of Lockport, in the county of Niagara and the State of New York, have invented a new and improved Coffee-Pot and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawing forming part of this specification, in which- Figure 1 is a vertical-section illustrating my apparatus when but a single spouting-tube is employed.

Figure 2 is a similar section illustrating the same with two spouting-tubes.

Similar letters of "reference in the accompanying drawing indicate corresponding parts.

This invention relates to that class of coffee-pots which contain a detachable apparatus consisting of a steam-generating chamber at the bottom, a drippingchamber at the top, and a tube connecting the steamgenerator with the dripper.

My invention consists of an improved construction of such apparatus, which renders it. less expensive and more convenient and effective than heretofore.

In the drawing-.

A is the body of the, coffee-pot, of any suitable shape;

B is the steam-generating chamber G is the chamber containingthe extract;

. D is the dripping-chamber;

E is the tapering-tube connecting the steam-generating with the dripping-chamber;

F is the nose or spout of the coffee-pot, provided with a cap, f, to prevent the escape of the aroma;

G is the handle;

H is a hinged bail for convenience in handling the coffee-pot, and for fastening down the cover when necessary; and

I is the cover provided with a fixed bail, t, which, when the cover is on, is designed to stand at right angles with the hinged bail.

The inverted cup, b, which forms the steam-cham her, and the tube E are connected together. and as a whole are readily removable from the cofiee-pot to facilitate its cleansing or to allow of its use for other purposes.

The tube E extends below the top of chamber B, nearly to'the bottom of the colfee-pot, so that the steam will rise above its open end and only boiling water will be carried up through it; my object being to make the extract by means of a jet or jets of boiling water, and not by a jet of steam alone, nor steam mingled with a small quantity of water, as heretofore.

The water being thus forced up by the pressure-of steam in the upper part of chamber B is sprayed over the whole snrfaceot' the coifee in chamber D by the action of a deflector, an, arranged directly above the open end of the tube E, as shown.

When only a single tube, E, is employed, as represented in fig. l, I make the deflector in the shape of an inverted cone soldered to the under side of the cover I, with its apex directly over and close to the center of the mouth of tube E, in which case the jet of water impinging against the cone will be das'hed in a sheet of spray equally in every direction.

When two tubes, E, are employed, arranged near the walls of the cotleepot, as represented in fig. 2, I prefer to make an independent cone, having a small handle, n, and insert it in the chamber, its, edge resting upon a wire flange or ledge, a, solde'red around the walls of the chamber, and its inclined roof directly over and close to thetops of the tubes, in which case its action upon the two jets will result in a very uniform distribution of the boiling liquid over the contents of the chamber.

I prefer the single tube and the inverted conical deflector on account ot' their superior cheapness of construction and their convenience in handling and cleaning, in allwhich respects-they possess great advantages over the old style of. deflector attached directly to the tube and supported by'it.

Both the steam generated in the coffee-potand'the spouting column of water may sometimes be sufficiently powerful to raise the cover I and allowthe aroma to escape, if not even to throw the boiling water over the sides of the coifee-pot. To remedy this I provide the stiff: bail i, attached to the cover,

and the bail H, hinged to cars upon the side of the pot A, and capable of being turned over the bail t", as

showirin fig. 2, so as to lock the cover down.

The hinged bail may be constructed of spring wire and made to curve outward at the sides, as shown at :qx, fig. 2, so that when the pressure. of the steam becomes so great as to endanger the safety of the apparatus the elastic wire will straighten out and allow the cover to rise far enough to permit the escape of some of the steam, when its elasticity will cause it to instantly force the cover down again and close the vessel steam-tight as before.

Little vertical slots, as, may be made in the rim of the cover to allow the steam to escape without lifting the cover entirely out of place.

Having thus described my invention,

hat I claim as new therein, and desire to secure by Letters Patent, ise 1. In connection with the chambers B 0 D and tube or tubes E of a cofi'ee-pot, the independent conical deflector in, supported by the walls of the sessei, and=operating in combination with said parts vnbstantialiy as described and for the purposes specithe-latter is constructed to look over the former as herein set forth, and for the purposes specified.

3. The outward curving bf said bail H as shown a: x, whereby it is made to operate as a spring when employed incombination with 'the cover I of a coffee-pot, 'substantieiiy as described and for the purposes set forth.

4. The slots s's in the cover I of a. cofiee-pot, in combination with the bails H c, substantially as and for the purposes described.
