<p>CO/mp/139 AUTOMATIC LOCKING DEVICE FOR THE LID-OPENING LEVER OF A PRESSURE-COOKER An automatic locking device for the lid-closing lever of a pressure-cooker. The lever is provided with an engaging portion designed for engaging a locking pin which is operated in response to the pressure within the pressure-cooker. The pin is mounted directly on the lid and interferes with the lid-closing lever in the lowered condition of the latter, in order to prevent said lever from rotating, and therefore prevent the opening when there is some pressure in the cooker.</p> |
