SU16830A1 - Oven, heated "Primus" - Google Patents

Description

The proposed adaptation to Primus refers to previously known devices — kitchens with gas passing between the housings and means heating the vessels through an oven and several concentric housings, the latter being movable relative to the bow, depending on the size of the heated vessel.

In FIG. 1 depicts a general view of the oven with the Primus installed inside; FIG. 2-general view of the oven; heated kerosene lamp.

The device consists of a funnel 3, the socket turned down. On the outer side of the funnel 3, which has a round hole in the upper part that coincides with the plane of the burner top Primus, the inner casing 4 and the lower part of the oven 1, having the form of a cylindrical tube, are attached. On the inner side of the same funnel, the second funnel 3 is fortified, also located by the socket down. The upper part of the device, which consists of three concentric housings 5, 7 and 8, is installed on the lower part of the device. The entire upper half of the device, which is a part of its oven, can be permuted vertically and fixed in each position pipe 1 using screws P.

Thus, the lit Primus is placed on the bottom of the oven 1, with a flame it is directly washed by the vessel B in it, which is introduced into the oven through the door 10. Hot gas, a passage in the annular space between vessel B and the casing 8, through a series of holes 9 in the latter, enters the annular space between the shells 8 and 7; further, reaching the end of casing 7, it rises again and, after passing the space between the walls of casing 5 and 7, enters the tube of the latter, through which all evaporation from the prepared food also goes.

If the Primus is replaced in the oven with a kerosene lamp 12 (Fig. 2), a stand 13 is mounted on the burner of the latter, carrying the funnel 14 facing downwards. At apex, at the top of the glass, there is a round hole 15 with a diameter slightly larger than . Above the funnel 14, two shells 16 and 17 are concentrically arranged. To the outer case 17 are fastened with screws 18, adjustable in height, the upper part of the device consisting of three concentric shells 19, 20 and 21. Of these, the inner case 21 is provided at the upper edge holes 22, 22 ... and put on the inner casing 16 of the lower part of the device; the upper outer casing 19 ends at the top with a lid 23

 a large hole 24 for the installation of the cooking vessel 26 and small holes: 25, 25 ... for the exit of combustion products. The heat developed by the lamp warms the bottom of the cooking vessel, exits through the openings 22, goes between the hoods of the covers 20, 21, rises through the space between the walls of the covers 20, 19 and leaves the openings 25, 25, .., as shown by arrows in FIG. . 2

The subject of the patent.

The oven is heated by a Primus, with several concentric housings, characterized in that the Primus 2, which is standing in the lower part of the tank, has the form of a cylindrical tube I, and two are turned on. With the threaded nozzles, funnels 3 and 3, and to the outer funnel 3, the inner casing 4 is attached, and on the marked bottom part 1 the upper part of the device is held in a height-adjustable manner by means of screws 11. Consisting of three concentric shells 5, 7 and 8, of which the inner 8 is significantly lower than the others, has a row of holes 9 at its upper edge and encloses the vessel 6 inserted into it, the bottom of which is directly washed by the burner flame, taper to chimney.

2. The form of the oven described in paragraph 1, characterized in that, in the case of the use of a kerosene lamp for heating it, it is equipped, instead of two funnels, one 4 and has a cover 8 on the outer casing 5 with openings for the vessel and for the release of gases.
