This invention relates to a cooking appa- 7 ratus with steam hood adapted to be heated by electricity or by gas. The invention'has forv its object to produce automatically at the correct time the controlling of the'so'urce of heat; For this purpose the water from condensation is utilized, according to the invention, which water collects under the steamhood as soon as the temperature for cooking has set in. An alarm signal may fof heat, i

be sounded at the controlling of the source An embodiment of the invention is shown, by way of example, in the accompanying drawing in which 7 Fig 1 shows in vertical section the cock. ing apparatus and part of 'thecontroll ng .mechanism. r v Fig. 2 shows the controlling mechanism for electric heating.

Fig. 3 shows the same mechanism tor gas heating". v f The cooking apparatus is composed of the heater plate 1 which has PIOjGCtlIlg angle irons 2, 2, of a trough-shaped metal ring 3 resting upon'said angular pieces 2, and of a' trough-shaped ring 4 which has an outflow pipe 5. The ring 4 is sllghtly inclined in order that the water from condensation collected in the samefiows towardsthe'outflow pipe 5. Onthis outflow 5, a finger 6 is fined which is hollow and perforated and on which, by means of a band 7,. a metal ball 8 is suspended. The band consists of .a material which dissolves in water,or which loses its solidity if soaked in water, for instance a strip of 'un's'ized paper as blotting paper or the like. A waterjpocket 9 1s further'arranged on the outfiow- On a'shoulder of ring 4 rests the steam hood 10v Which covers the two pans 33, 33 which are placed the one on the other. v

a The controlling mechanism, Fig. 2, is arranged on an insulated plate 20, A1 scale beam 12 oscillatably'mounted on an axle 11 has at one end a hook 13. The other end of the beam 12 is normally pushed upward by the action of a spring 14. The hook 13 grips then over the interrupting lever 15 oscillatable around a pin 23 and pushed upprovidedy the latter cook 28; A fixed on said cavity of ring 3 so that 126,000, and in Germany March 16, 1925.

ward'by the action of a spring 22. The arm 12 carries a cup 19, the ball 8 and it carries furthera locking bolt 16 bearing from'behind against the lever 17 of a clockwork bell 18 andjlocking thusv the escapement of the clockwork.

The switch lever 15 comprises an insulated headpiece 21. The pivot pin 23 forms one of the contacts the second contact being formed by a terminal 24 in which the switch lever 15 is clamped. Terminals 25, 26 are nected to the contact "In the 3 the gasflows from the gas main through a tubularv socket 27 to the casing of the second tubularsocket 32 is clock casing and designed to conduct the gas to the heating plate 1. On. the cook 28 an arm 29 is fixed, a blade spring 30 tending to turn thisarm upwards. In order-Ito llllllt'thB oscillating movement of said arm or lever 29 and to regulate thereby the amount of opening of the gas cock, a stop screw 31 is provided. The other ele ments of the mechanism are the same as, those shown in Fig. 2 and they aredesignated by the same reference numerals- The pans 33 project over the rim of plate 1 into the cavity of the metal ring 3, said metal ring 3 intercepting liquid from boilmg over, so thatthls liquid cannot get onto the plate 1.. he ring 3 serves further to.

protect the ring 4 against excessive heating, so that the evaporation of the water from condensation intheiing 4 is prevented. If necessary water might be filled into the it evaporates and increases the heating effect. According to whether the operation of the controlling mechanism has to be produced is previously form' of 'construction'shown in Fig.

at once ora "httlelater by the collected water from conwhich stands underneath being electrically conso that, on the one hand, it releases the lookoperates said gins to sound, and, on the other hand, releases, if electric heating, the switch lever 15, and it gas heating, the cock lever 29, these levers being pushed upward by the action of the springs 22 or 30. At electric heating the current is thus interrupted, and if gas heating the cock is either entirely closed or partly closed, in accordance with the position of the stop screw 31 If the water pocket 9 is empty or only partly filled, this operation is retarded. The electric cooking plate may have several circuits, so that the electric heating can be switched to feeble heating inaccordance with the circuits.

As'the steam hood 10 rests upon a shoulder or ring 4 it is protected against being dirtied by the water from condensation. It may be less high in accordance with the hei ht of the shoulder.

l or gas heating the metal ring 3 is placed upon a gas cooker which is mounted at such height that the outflow pipe has approximately the same distance from cup 19 asat electric heating. The lower pan stands then directly over the gas burner. i vvThe cooking apparatus described presents the further advantage that the rings .3 and lare only-loosely connected with the electric heating plate or with the gas cooker, and that the controlling mechanism is mounted separate from the source ofheat, so that allfelements canbe easily cleaned. The apparatus might be used for baking if the ring 4; and the out flow tube 5 areomit ted, and the steam hoodis placed directly into the metal ring 3, sothat the hot gases flow under the hood and around the mate.- rial to be baked.
