Abstract: 372,768. Electric cooking apparatus. REICH, E., 7621, Greenview Avenue, Chicago, U.S.A. Feb. 5, 1931, No. 3712. [Class 39 (iii).] An appliance for cooking or heating food, e.g. for grilling, comprises a pair of electrically heated plates 30, 33 mounted so that they can be moved towards and away from one another whilst remaining parallel and arranged to counterbalance one another. In the appliance shown in Fig. 2, levers 21, 22 are pivotally secured to a pair of standards 16 mounted on the top of the hollow base 10 and upright posts 23, 27 are pivotally secured to the ends of the levers. The lower plate 30 is rigidly secured to the top of the post 27 and the upper plate 33 is pivotally secured to the top of the post 23 ; the pivotal connection between the plate 33 and the post 23 includes a vertical slot in the plate 33 so that the plate 33 is in floating relation to the plate 30. The upper end of the post 23 terminates.in a horizontal bracket 26 which supports a projection in the plate 33 and holds that plate in horizontal position. A lug 35 on the plate 33 is adapted to abut against a stop pin 36 on the post 23 when the plate 33 is swung into upright position. By exerting a pressure on handles 39, 32 the distance. between the plates may be varied. Springs 40, the tension of which may be varied, are connected to the bottom of the posts and to the casing and serve to bring the plates together. In the appliance shown in Fig. 7, the top plate 33<1> may be swung into position to form a horizontal extension of the bottom plate 30<1>, the horizontal bracket of the post 23 is dispensed with and the plate 33<1> is mounted in position by the engagement of lugs 46, 47 with the pin 36. In the appliance shown in Fig. 10, vertical rods 52a, 58 are pivotally secured to levers 53, 54 which are pivotally secured to cross-shafts 51, 52 in the base. A heating plate 62 is secured to the rod 52a and a heating plate 64 is connected by means of a pin 79 passing through ears 80 on the plate 64 to a hinged arm 63 which is adjustably mounted on the rod 58 ; in this way the plates may adapt themselves to uneven articles placed between them. The heating surface of the upper plate terminates in a flange 83 which enters a trough 73 extending round the lower plate. The upper plate may be inverted, the oscillatory movement of the plate 64 on the pin 79 being limited in one direction by ears 85, 80 and in the other direction by the arm 63. The plate 64 may be held inverted by a spring-pressed bolt 87 engaging a rear extension 86 of the plate. An arm 98 is secured to the shaft 51 and is connected by a spring 99 with a cross-pin 100 connecting the levers 54. An arm 102 secured to the end of the shaft 51 projecting beyond the base has a bolt 104 adjustably engaging a toothed segment 105 on the frame ; in this way a regulatable pressure may be exerted on the material between the plates. In the modification shown in Fig. 11 the lower plate is secured to the frame, the weight of the movable plate being balanced by a weight 271 provided on a cross-rod connecting the arms 27. An opening may be provided in the cover of the base for the reception of a cup 45.
