Description

The main patent No. 12082 describes a fixture for a burner of the “primus type” type, which consists of a duct containing a primus with an opening in the bottom for air flow and from an oven or an open cooking box placed on the duct; It was therefore envisaged that a cap and screen be used to shield the tank from being heated by a torch. The modification of the oven according to the main patent, offered additionally, concerns the device of lifting and turning installations, allowing to remove the primus without removing the oven

and a cap, and corresponding improvements in the cap and in the screen.

In the drawing of FIGS. 1, L and V depicts an oven with the installation of a primus (respectively, a side view „on the top and details), FIG. 2 - the lower part of another installation in the working position (side view), FIG. 3 and 4 - the same, respectively, side view and from above, FIG. 5, b, 7, 8 and 9-cap and a mechanism for closing its opening with separate parts, fig. 10 and 11 - the lower part of the oven with a split screen (side and top view).

The oven is placed on a stand that is out of frame 1,

standing on legs b (Fig. V). A metal sheet 8 is attached to the frame 7, with which the cap 1 is fastened. The legs of the stand 6 are attached by means of metal brackets, platform 3, on which platform 2 (Fig. 1 and 1), equipped with handles 13, is resting. guide axis 5 and bolts 4. Platform 3 has holes for legs 4; when the legs 4 become in the corresponding holes of the platform 3, the platform 2 descends on the platform itself. Then a primus is installed on the platform 2, then the platform together with it lifts the pins 13 until the legs 4 come out of the holes; The platform 2 turns around a certain angle and the knife 4 is placed on the platform 3 itself, while the burner of the primus falls inside the cap 1. The platform 2 can have a device of ribs 14 for proper installation of the primus (Fig. 1 and which are attached to the platform 2 or The outer casing 16 of the furnace does not have a bottom plate, the role of which is played by a metal sheet 8. The oven is resting on frame 7 with frame 9 or plates of appropriate shape. Thus, the inside of cap 1 is connected to the air space m EzhDu metal chamber 15 of the furnace and the casing 16. In the latter there are a number of holes 10 through which the air passes to the burner of the primus. The cap 1 can be arranged according to the basic patent or in the form shown in Fig. 1 and 1. The last count of K consists of three conical segments of smaller diameter and three conic segments of larger diameter, which are connected by corresponding meridian planes. When lifting the platform 2, the cap passes the legs of the primus and allows the platform to rotate by a certain angle. In cap 1, there may be a window for observing the flame of a primus stove.

Another type of installation of a primus stove in the oven is shown on the screen. 2, 3 and 4. The platform 2 can move down and down, but cannot rotate. The plate runs along two guide rods 33 preventing its rotation. With pad 2, pad 38 is connected by means of axis 38 with three legs 34, which can rotate around axle 38. So that guides 33 do not interfere with the rotation of pad 1 ,. In the next rf there are slots 44 of the corresponding form (in Fig. 4 they are indicated by a dotted line. The slots 44 regulate the possible differential of the platform 1 around the axis 38 fixedly attached to the platform 2, and the guide rods 33 serve as rotation stops. pivoting platform 1 is raised, its 34 is standing on the supporting platform 36 (Figs. 2, 3 and 4) .When the same platform 1 turns at a certain angle depending on the size of the cut through, the LEGS 34 fall over the holes 35 "G1 platform 36 , and pad 1 together with pad 2 attached to it, can be op scheny down at what legs 34 are buried in the holes 35 (phi. 4). In the turntable 1, there are two handles 45,

The gatekeys serve to raise, lowering its rotation around the axis 38.

- FIG. 5 shows the cap described in main patent No. 12082, and the mechanism for closing the opening of the cap through which the primus burner is introduced. ; In its lower part, the cap 8 is connected to the cylindrical part, more

shown in detail in FIG. b, 7, 8 and 9.

An axis in the form of a ring 30 is attached to the said cylindrical part, on which there are six sectors 6 (the number; they can be arbitrary). Sectors b have bent appendages 27 (Figs. 5 and 6), and c; a circle of a cylindrical cap and using p: lever 5 (Fig. 5) to turn around the cage 7. By rotating this cage touches the processes 27, which causes the b sector to turn on | Its axis 30 opens the lower opening for the passage of the burner to the Primuseum. The holder 7 is provided with cutouts for the passage of the processes 27 of the sectors b, each cut being limited from one side to the contour 32 (FIG. 5), which, when the holder is rotated, presses the process 27. In FIG. . 7, 8, and 9 depict the lower cylindrical part of the cap, fitted with flanges 2; 9, which serve as supports for the holder 7, and with ears 28, in which axis 30 is resting. Border 31 and edges 29 serve as reliable guides for the rotation of the rib 7 (Fig. 5 and b). FIG. 5 shows the viewing window 25 in the cap 8.

To install the primus on the lifting platform 2 (Fig. 3 and 4), a screen 3 with a slot 42 for the primus legs is attached to the casing 40 on it. A primus tube supplying kerosene to the burner rests against the rim 43, which ensures correct and durable installation of the kerosene. This screen 3, however, protects the tank from overheating.

A screen of another type, detachable, is shown in FIG. 10 -11. It consists of a fixed part 58 attached to the casing 52 of the lamp, and a lower part 59 attached to the door 53. The fixed part of the screen 58 is arranged like the screen 3 in FIG. 1, 3 and 4. Both parts of the screen 58-59 are attached to the corresponding part 1 of the cap 56-57 (described in the main patent), which gives the entire structure strength and rigidity.

When the platform 1 rotates clockwise, the rod 4 (fig. 1, 3, and 4) attached to the platform rotates the holder 7 (Fig. 1 and 5) of the holder 7, which causes all sectors 6 to rise. At the same time, the legs 34 of the platform 1 are located above the corresponding holes 35 in the platform 36, and the platform 1 together with the platform 2 can be lowered onto the platform 36, with whose Irimus burner comes out of the cap 8, and the primus can be easily removed from the platform . When turning the knobs 45 (Figs. 3 and 4) in the direction opposite to the clockwise movement, the pad 2 together with the primus is fixed in the raised position, with the rod 4 turning the lever 5 of the yoke 7, the yoke sector with its own string or by means of the springs are lowered, closing the hole in the cap 8, through which the stove of the primus was inserted.

The modification of the wind scaffold described in patent No. 12082, characterized in that the scaffold for the installation of a primus is provided with an upper platform 2 with handles 13 turning on the central shaft 5 and having legs 4 passing through the holes B in the platform 3 and 3 with the platform 2, and abutting against the platform 3, when the platform 2 is raised and turned at some angle (Fig. 1,

, G ,. 1 and d). To j-, VY

2. Modification of the cabinet indicated in paragraph 1, characterized in that for setting the primus to the roof of the lifting turntable 1 with the legs 34 there is also another, also lifting, but Herio 2, on which the primus has, fitted with guides 33 and connected pad 1 with the axis 38 (Fig. 2. 3 and 4). ,

3. Variation of the cabinet described in Sections 1 and 2, characterized in that to close the lower opening of the yolpack 8, moving sectors 6 with curved processes 27 are used, for which the lugs of the holder 7 are hooked during its rotation in order to move the sectors 6 (Fig. 5 9).

4. The change described in pp; 1-3 cabinets, characterized in that in order to protect the primus tank from heating, the oven is provided with a screen 3 located in height between the burner and the primus tank and having a side 43 for the centering of the latter in relation to the kerosene-inlet tube or a cup of a stove burner (Fig. 3 and 4}.

5. When characterized in c. In the cabinet, the use of a screen consisting of two parts, of which a large part 58 serves to center the primus, and the other part 57 is movable and arranged to change its position relative to the fixed part of the screen 58 (Figs. 10 and 11).
