v "1922; j Serial x 601,156.

Be it known that I, FRANK a.'--citizen o f'the United States, and resi-' dent of the city OfNew York, borough of Manhattan, in the, county and State of New York, have invented a new and Improved Coffee-BrewingApparatus, of which the following is a full, clear, and exact description.

Among "the principal objects which the 1, present invention has in view are: to provention, showing in conjunction therewith a 'vide means for brewing cofi'ee or similar beverages for small consumption; to" purvey small quantities of a table beverage for individual consumption; to vary the strength of said beverage; to provide for quickly'brewing a small quantity of table beverage for individual consumption; and to proportion the quantity of the material froln which the beverage is concocted to ,the demand for the beverage.-

Figures 6 and 7 are-detailed views in section, showing the disposition of the conter to' various partsof'the apparatus;

r :As'seen in the a drawings,'a rotary valve:

10 is placed in a tubular valvecasing 11, wherein port-s 12 and 13 are provided-for establishing. communication between the water chamber 14 and the brewing-chamber.

. 15,-'when the water controlling valve pas H. SIMoN'roN,

. sage is proper-ly disposed. The pan holdc1217 is cast from metal and is preferably integral with the valve casing 11. v, The container 16 is preferably constructed of glass and is open at the bottom only, so as to provide for an air space above the water '18, being" trapped and compressed thereby as thew'ater enters and fills the-container; In

practice the full volume of air in the-con tainer 16 is compressed at the upper end thereof, until the expansion force equals the head pressure of the wate entering. It is obvious that when the valve 10 is turned to place thewater channel 19 in communiof the water being :due to the compressed air at the upper end of the chamber 16.

A pan 20has a spout 21 centrally 10- v catedtherein. The pan 20 has an inturned flange 22, the uppe surface of which is beveled to form a tight joint with the lower edge of the holder 17., Theupper edge of the flange 22 forms a rest for the outturned flange 23 of the circularside of the cup 24.

The cup 24 is furnished with a close meshed sieve. bottom 25, upon which in practice the pulverized coffee rests. The

pan 20 is vremovably attached to the holder 17, hooks 27 being provided for this purpose. shanks 2810f handles 29 rise on the upper edges of thehooks 27, the said upper edges being slightly'inclined to wedge the inclined surface of the flange 22 into intimate contact with the lower-edge of the holder 17. When the pan 20 and the holder 17 are so connected, the chamber 15 is tightly closed except through the coffee 26 and spout 21.

Both water H and steam are delivered to thechambers l4 and 15. To this end, two pipes'30 and'31 are provided. In service,

structure by any suitable :means. The pipe 30 is-connected with some source of boiling water; The pipe-31 is connected with'a steam source. .7

i The valve channels 19 and'33lare disposed The- - to' the chamber 15.

'or packed with pulverized coffee.

in the same vertical plane and may coincide with the opening of the pipe 30 and the ports 12 and 13. The valve passage 34 is disposed in a vertical plane incorporating the opening of'the steam pipe 31 and the port 35. As seen best in Fig. 3 of the drawings the port 35 is laterally disposed with reference to the ports 12 and 13. The valve 10 has a stem to which is connected an operating handle 37.

Operation. The apparatus herein disclosed is designed primarily to meet the needs of restaurants where coffee is one articles dispensed.

Great difficulty is experienced in satisfying the individual tastes of a number and variety of customers. When equipped with a number of apparatuses such as herein described, a number of; cups 24 are supplied When a demand is made for coffee, thewaitress takes one of the packed cups and places it in the pan 20, To do this, she firstremoves the pan 20 by rotating the cup to the position where the handle-s '29 become disengaged from the hooks 27. When the cup 24 is placed in the pan 20, said pan is again placed in supported relation to the holder 17, being tightened by the hooks 27. The handle 37. is then turned from the position shown in broken lines in Figure 1 to the position shown in full lines in said figure.

of the. staple This latter position corresponds with the disposition'of the valve 10, as seen in Figures 2 and 4. It will be observed that in this position, thelport channels 19 and 33 are in communication with the pipe 30 and with the chamber 14, while simultaneously the port channel 34 has been placed in communicationwithpthe steam pipe'31 and the chamber 15. In these positions of the said port. channels, boiling water is delivered to the chamber 14 and steam Water and steam continue flow simultaneously until the water is arrested by the air pressure at the top of the chamber 14. When the operator observes that the water has ceased flowing, she moves the handle37 to the position indicated by broken lines in Fig; 1, which position is shown -best in Figures. 5 and 6 of the .drawings.

channel 19 is disposed to permit the water 18 to flow from the chamber 14 into the holder '17 and chamber 15 thereof to be spread on the plate 38 and thence precipitated upon the coffee 26..

During the period in which water is admitted to the chamber 14, steam is introduced into the chamber 15, with the effect that the coffee 26 in the cup 24 is cooked or In this position, it will be observed: the steam supply is discontinued while the preheated. When, now, the valve is turned so that the steam supply is discontinued j been placed thereunder.

If for any reason it 'is desired to further extract the essence or strength of the coffee, the valve 10 is moved to the position shown in Fig. 7 where the channel 39 is placed in communication with the steam pipe 31 and the port 35. In this position of the valve,

the channels 34, 19 and 33 are out of register with any of the ports above referred to and steam only is delivered through the valve and to the chamber 15.

I/Vhen the individual brew has been completed, the cup 24 is removed and suitable disposition is made of the coffee grounds.

From the foregoing it will be seenthat the functioning of the present invention consists in providing means for preliminarily introducing steam into the body of the coffee for a definite period; then introducing heated water in predetermined quantity through the said coffee; and then again introducing steam into the body of the coffee. The result of the successive operations is that the body of the coffee is first saturated with a hot steam which prepares it to the best advantage to receive the hot water, and after being acted upon by the said hot water, the second introduction of steam eliminates the water from the body of the coffee.

While in the above specification I have described the container 16 and function thereof as a regulator for the amountof water to be used, it will be understood that other means commonly known to the art, may be employed for delivering to the body of coffee, the required amount of water without employing said chamber 16. Therefore I do not wish to' be limited toan apparatus employing the said chamber 16.
