Convention date, Jan. 18, 1934. [Classes 28 (i) and 81 (i)] [See also Group XXIX] An apparatus for generating superheated vapours, especially steam, for cooking, steaming, sterilizing, and similar purposes, comprises an outer container 10, an inner vessel 13 detachably supported by the outer container, and a superheater coil 26 arranged below the container 10 to be exposed to the source of heat, the coil communicating at one end 30 with the steam space of the container 10, the other end 32 being arranged to deliver the superheated steam to the vessel 13. The vessel 13 rests upon a packing 17 and is retained in position by a screwed nut 40 threaded on the pipe 32, the nut having arms 43 for supporting a basket 44 for the articles to be treated. The pipes 32, 28 pass into the top of a member 35 having two side openings, one in communication with each pipe 32, 28, to receive the ends of the coil 26. The member 35 is secured to the bottom of the container by a screwed ring 37 which is threaded on the member 35. Wire gauze 41 prevents foreign matter from entering the vessel 13, and a depression 42 is provided in the bottom of the vessel to collect water and impurities. The container is provided with a filling-plug 12 and a vent pipe 45, and the lid of the vessel 13 has a vent hole which is normally closed by a pivoted plate movable between stop means. The vent pipe 45 may be provided with a device, Fig. 5, consisting of a pipe 49 closed at its top and secured to the pipe 45 by a union nut 47. A cross pipe 50 is secured to the top of the pipe 49 which communicates therewith through a side aperture 53. The pipe 50 is closed by end members 51, one of which has a perforation 54 in its upper part which is screened by a plate 35 which directs any water ejected by excess pressure downwardly. A throttling member 59 may be fitted to the upper part of the pipe 45. The pipe 50 is covered with insulating material 57 to enable it to be used as a handle. When used for sterilizing, the apparatus may be fitted with a thermometer.
