JOSEPH MARTIN LAWRENCE, OF HOUSTON, TEXAS.

COFFEE-POT.

SPECIFICATIQN forming part of Letters Patent No. 349,505, dated September 21, 1886.

Applicationfiled February 9,1886. Serial No.191,361. (No model.) i

To all whom it may concern:

Be it known that I, JOSEPH MARTIN LAW RENCE, of Houston, in the county of Harris and State of Texas, have invented a new and Improved Coffee-Pot, of which the following is a full, clear, and exact description.

The invention consists of the construction, arrangement, and combinations of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of my new and improved coffee or tea pot. Fig. 2 is a sectional plan view taken on the line {C x 00 w of Fig. 1, and Fig. 3 is an inverted plan view of the false bottom removed from the pot.

The pot A may be of any desired form and size. In it is placed the false bottom B, which is provided upon its under surface with the flange O, for. holding it a short distance above the main bottom aof the pot, and the false bottom is of slightly less diameter than the pot A, to permit the false bottom to be easily removed from the pot and to furnish space between it and the walls of the pot for Rising from the false bottom B are the two tubes D D, which are by preference slightly tapering and curved at their upper ends to form the nozzles (Z d, for discharging the fluid into the receptacle E. The upper ends of the tubes D D are connected together by a crosspiece or bridge, (1, for bracing and strengthening the tubes, and the receptacle E is suspended from this bridge 01 by suspending rods or hooks e 6, so the receptacle stands between the tubes and under the nozzles d d. The flange O is by preference Sshaped-and attached to the under side of the false bottom B, so as to direct a current toward the lower openings or months of the tubes D, as shown clearly in Fig. 3, openings 0 0 being formed to admit free entrance of the fluid to the spaces inclosed by the curves of the flange. The receptacle E is in the form of a strainer and may be made of perforated sheet metal or wire-gauze; but I prefer to use cloth, in which case I employ two rings, f f, for holding the cloth. The inner ring, f, is of slightly less diameter than the outer ring, f, and the above-mentioned suspending-hooks e e are secured to the inner ring.

In forming the receptacle with the rings and cloth the latter is placed over the inner ring and pressed downward to form a pouch. The edges of the cloth are then folded. over the upper edge of the inner ring and the outer ring placed upon the inner ring and cloth, thus binding the latter in place.

In use the tea or coffee is placed in the receptacle E and the receptacle hung upon the bridge d. A suitable quantity of water is now placed in the pot and the pot heated. As the water becomes heated, it will be forced by the action of the heat up the tubes D D and discharged in continuous or nearly continuous streams from the nozzles d (1 into the receptacle E, so the strength of the tea or coffee will be extracted by the passage of the water repeatedly through the receptacle. The false bottom B is held down in the pot A by the.

the tubes having their upper ends bent downward, a bridge or cross-piece, d, connecting their upper ends, the suspending-rods e e, depending from the bridge, the ring f on the lower ends of the'suspending-rods, the ring f,

and the separate strainer-held removably between the two said rings, substantially as set forth.

2. An attachment for coffee-pots, comprising the false bottom B, the flange O on the under side of the same, curved to form two chambers having opposite side openings, 0 c,

the tubes D, extending upward from the false bottom and communicating with the upper parts of the two said chambers, the nozzles d d, and the strainer suspended below the nozzle, substantially asset forth.

JOSEPH MARTIN LAWRENCE.
