KARL BECKER, OF BERLIN, GERMANY.

COOKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 471,374, dated March 22, 1892.

7 Application filed June 4-, 1888. Serial No. 276,057. (No model.)

T0 at whom it may concern.-

Be it known that I, KARL BECKER, of Berlin, Germany, have invented an Improved Cooking Apparatus, of which the following is a specification.

This invention relates to an improved cooking apparatus in which the cookingis effected by steam or water bath.

The invention consists in the various features of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal vertical section of my improved cooking apparatus on line a: as, Fig. 2; F1g. 2, a horizontal plan, partly in section, on line y y, Fig. 1, but with the right-hand cover g and vessels b removed; Fig. 3, a rear view of the apparatus. Figs. 4 to 9 are sections through the water-controlling cocks, showing them in difterentpositions. Figs. 10 to 12 are details of the graduated disks to and the cooks.

The letter it represents a boiler placed centrally in a range and having both a watersupply and a water-discharge, which are hereinafter more fully described. The water-discharge carries the water to a pair ot' waterboXes g, inclosing ovens t and provided on top with flanged or plain pot-holes for the reception of the cooking utensils I). To the boxes g there are connected by hinges g lids or weighted covers 9 that may be swung down upon the vessels 1), so as to hold them down in the water.

From the rear of the apparatus there projects upwardly at the center of each lid a hollow post f, carrying a pulley f Over this pulley runs a rope or chain f that is attached at one end .to the lid g and carries at 1ts other end a weight fflinclosed within hollow post f. The weight f thus constitutes a counter-weight for the lid and facilitates the raising and lowering of the same. \Vithin the boiler h there is inclosed the fire-place c, and also an oven e beneath the fire-place.

At each side of the fire-place c and at the back thereof there are placed three (more or less) downtakes or fiues (Z. Two of these lines are shown in section in Fig. 1, while all the fines are indicated by dotted circular lines in Fig. 2. The fiues 61 enter on top the hot-air space beneath the top plate a. of the stove, and thus communicate with the fire-place a.

At the bottom the tines cl communicate with a heating-space d, encircling oven 6 and communicating in turn with a flue f, that passes through the boiler h and enters the chimney. The products of combustion travel from the fire-place c first under the top plate a, thence down the fiues cl into the heating-space d to heat oven e, and thence to the exit f into the chimney.

The water is fed into the boiler h from an elevated tank m. Into this tank enter two pipes s t,.the former opening at the bottom and the latter near the top of the tank. At its lower end the pipe 8 communicates with the socket of a three-way cook a, while the pipe t communicates with the socket of a similar three-way cock 0. Vertically above the cook a there is a two-way cock n, while vertically below the cock 0 is a two-way cock 0. The sockets of the two upper cocks communicate by pipes n o with the boiler h, and the sockets'of the two lower cocks communicate with the boiler by similar pipes. (Dotted lines, Fig. 1.) Moreover, the sockets of all four cocks are coupled to laterally-extending pipes Z0 is Z Z, Fig. 3, that'carry the water from the boiler to the cooking-boxes. All four cockplugs carry cranks 19, connected by rods q. One of the cooks n is connected to a handle w, that projects to the front of the stove and by which all four cocks may be simultaneously operated. In order to regulate the position of the cocks, the handle 20 carries a graduated disk u, cooperating with a fixed index-finger on the stove. It will be seen that water is from tankm admitted through cocks n 0 into the boiler. Here the water is heated and passes through all four cocks into the cooking-boxes. When, however, by a turn of the cooks the water-boxes g are cut off from boiler h, then a circulation of hot water will take place through pipes s 2?, cocks n 0, and the elevated tank on.

The position of the cooks to create the-different circulations is shown in Fig. 4 to 9. In Fig. 4 the boiler his connected to the waterboxes g, but the tank m is cut off. In Fig. 5 the cook a is connected to the tank m, but the cook 0 is cut off. In Fig. 6 the cock 0 is connected to the tank at, but the cock n is cut off. In Fig. 7 the boiler is connected to the tank at alone, while the water-boxes are cut off. In Fig. 8 the boiler is connected with the left-hand cooking-box g, and in Fig. 9 the boiler is connected with the right-hand cooking-box. Above the level of the two uppermost cocks n 0 there enter into the boxes g a pair of overflow-pipes r. Vhen the water in the boxes has risen to the top or inlet openings of said pipes, it flows out and prevents the apparatus from becoming flooded.

It is evident that in this apparatus a continuous circulation may be kept up, owing to the heating of the water in the boiler and the pressure of the water in the tank. Thus the cooking utensils Z) may be subjected to the heat radiated from a continuously-circulating body of water. The cocks should be opened only sufliciently far to cause the circulation to supply evaporation. Thus the water-level will remain uniform in the water-boxes and flooding will not take place. Should, however, the cocks be opened too far, the water will run out of the overflow, which will be a. notice to the attendant to shut the cooks.

hat I claim is- 1. The combination of boiler h with cocks 'n n 0 0, pipes s t, communicating with alpair of said cocks, cooking-boxes communicating with all of said cocks, and a raised tank communicating with the pipes, substantially as specified.

2. The combination of boiler h with the water-boxes g, elevated feed-tank m, pipes st, and valves 07. n 0 a, substantially as specified.

3. The combination of boiler h with a pair of three-way cocks at 0, pipes s 25, connected thereto, a pair of two-way cocks n 0, pipes k 76' ll, connecting with the cooks and with a tank m, and water-boxes g, connected to pipes s t and is k Z Z, respectively, substantially as specified.

4. The combination of boiler h with cocks u n 0 0', cooking-boxes g, raised tank m, communicating with the boiler, cranks p and rods q for connecting the cock-plugs and" with a handle to, and a graduated disku for adj usting said plugs, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

KARL BECKER.
