SPECIFICATION forningvpart of Letters Patent No. I7648,91@ dated'anuary 5, 1904.

Application liled November 19, 1902. Serial No.1131,940. (No model.)

To all whom it may concern:

Beit knownthat I, FINLEY ACKER, a citizen of the UnitedStates, residing in the city and countyof Philadelphia,State ofPennsylvania, have invented new and useful Improvements in Codec-Urns, of which the following is a specication.

My invention consists of a codec-urn which is composed of an urn proper,'a vessel for receiving ground coffee, the same having a per;v colator and water-spraying device therein, a chamber for measuring the amount'of water desired to be converted into iiuid coffee, and a tank for primarily boiling the water from which t-he coffee is to be made, the parts being hereinafter described and the novel fea tures of the samebeing' pointed out in the claims.

Figure l represents a vertical section of a coffee-urn'embodying my invention. Fig. 2 represents a side view of a detached portion thereof. tion on line w as, Fig.i 2. Figs, 1i and 5 represent top views of detached portions in dierent positions. v

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a tank, thesame being adapted for primarily receiving water, and is provided with a coil A', of steam-pipe, or an electrical or other device whereby the water in said tank may be boiled. Connected with said tank is a vessel B, which is in communication with said tank A by means of the valved pipe C, said vessel having a heating or boiling device B' and a gage D for indicating the height of water in said vessel, said vessel serving to measure the water for the quantity of fluid coffee it is designed to make, it being also provided with a vent E, the same being open to the atmosphere for-evident purposes. f

F designates what I term a codec-maker and which lconsists of a cylindrical or other shaped receiver G' inl com munication withthe chamber B by means of the pipe H. At the base of said receiver is the valved pipe J, which is connected with the urn K. Within the receiver, at the lower portion thereof, is the strainer and filter-plate L, above which is a foraminous dome-shaped or convex diaphragm N, which depends from the tube M,

Fig. 3 represents a horizontal sec' the upper portion of which is open, forming the vent'P. Fitted on said tube above the diaphragm. N isthe Yhanged tray Q, the bottom of which is perforated or foramnous, said plate being adapted to be held at various heights in regard to the amount of'ground codec to be used by means of the. ring R and screw or pin R', which latter 'may be placed in either of the openings S in the side of the tube M one above the'otherr.

1 Depending fromY the bottom of the vessel B is the collar T, in the side of which is the angular slot U, which is adapted to receive the pin V as a bayonet-joint, said pin projecting outwardly from the sleeve W, which enters the collar T, and has a iiange X on its upper end, the same normally resting on the bottom of said collar, thus limiting the descent of said sleeve and properly holding the same in position, it being noticed that said sleeve forms aV downward continuity of the pipe H audits lower end freely enters an open-v ing in the lid G of the member-F, so that water iiowing from the vessel yB through the pipe H passes through the sleeve W and the opening in the lid G', and so enters the receiver G. The pipe .I at the bottom of the receiver G freely enters an opening in the lid K of the urn K, it being noticed that the coee-maker F rests on said lid K'. NowA when it is desired to displace the coffee-maker, either for receiving the codec-grounds or replenishing the same with ground coffee or for other purposes, the sleeve W is raised, whereby it withdraws from the lid G and is elevated above the same. The pin V ascends in the vertical member of the slot U, and when it reaches the horizontal member thereof it is turned thereinto, whereby the sleeve is sustained in its elevated position. The coEee-maker may now be raised, the pipe J at' the bottom thereof emerging from the opening in the lid K,thns discon nectingthe codec-maker from the urn and removing it therefrom.

' Y designates the vent-pipe of 'the urn K, the same opening into the 'interior thereof and having an outwardly-extending branch Y, so that air can enter theurn to permit the discharge of the lfluid coee when the cock Y2 is opened, it being noticed that the head Y3 of said cock has a segment Z on the rear portion of its periphery, the same being IOO adjacent to the open end of the branch Y', sothat when the cock is closed the said segment abuts against said end of the branch and closes the same, and consequently the Vent-pipe, thus preventing the escape of the aroma of the coffee in the urn. When, however, the cock is opened, the said segment of the head moves from the end of the ventpipe and uncovers said end, whereby air may enter the Vent and supply the interior of the urn for purposes hereinbefore stated. (See Figs. 4 and 5.

The operation is as follows: The sleeve is raised, as hereinbefore stated, and the coffeemaker is disengaged from the urn. The lid G' is removed and the tray Q withd rawn. The proper quantity of ground coffee is now placed in said Vessel and rested on the diaphragm N, after which the tray is returned to its adjusted position, the cover of the vessel reapplied, and the coee-rnaker restored upon the urn. The sleeve W is now lowered and inserted in the lid G', as in Fig. 1. It will now he noticed that the amount of water supplied from the tank A to the measuringchamber B may be adjusted by means of the valve in the pipe C. The boiling water then iiows through the pipe H and sleeve W into the vessel Gr and passes through the ground coifee on the diaphragm N, thus making an infusion of the coffee. The valve J`is opened after the oo'ee has sufliciently infused and the beverage percolates and filters through the plate L, and so enters the urn K. It will be noticed that the water entering the Vessel Gr passes through the tray Q in numerous streams or sprays, owing to the openings in the bottom of said plate, and so is thoroughly distributed over and upon the ground coffee. In some cases it may be desirable to supply the vessel G with only a small quantity of water in order to saturate the ground coffee and then to admit a larger supply of water, which is sprayed upon the ground coee and caused to directly circulate through the diaphragm N and the strainer and lter below the same.

The tank A, thechamber B, the vessel G, and urn K are suitably jacketed and may be insulated or packed in order to retain the heat within said parts. The tank A and vessel B Will be supported in any suitable manner.

Various changes may be made in the details of construction without departing from the general spirit of my invention, and I do not, therefore, desire to be limited in each case to the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a coffee-making device, a primary heating-tank, a water-measuring tank and a coffee-making vessel detachably connected with said measuring-tank.

2. In a coffee-making device, an urn, a coffee-making vessel mounted 'on said urn, a water-tank on said vessel, detachable liquidconveying connections between said urn and said vessel and between said vessel and said tank and Valves controlling the iow of liquid through both said connections.
