The length average and the horizontal section CD set in g the containing of sheet iron-constructed approximately 40 1 main boiler for boiling the water is. The same is provided α with hollow walls a, and in the center with the above in a flue pipe opening into the heating tube and has below the firebox with the sliding door (heating door) h. Under the grate k lies the ash container i, which can be closed by means of a slide, and which is insulated below by a space filled with wood ash. The float b, held by the guide wires 0 , whose handle moves above the kettle in a glass tube provided with marks, serves as a water level indicator for the filling of the kettle g. «' A ^r are the openings for the discharge of any steam escaping through the safety valve c.

The filling takes place through the opening e by means of an insert funnel.

The water heated to the boil rises due to the steam pressure through the pipes d into the reservoir /. The rise of the hot water is regulated by a tap.

The water, which is now heated again in / by means of the furnace with grates k, heating doors h and ash container i , is driven further into the riser pipe η and sprays through the small holes in this pipe above into the coffee grounds container q. The vapor tension is regulated by the valve ρ .

While the water rises in the tube d, the otherwise closable air shaft ζ (see top view and front view) must be kept open. The level of the water in / is indicated by the water level glass y .

The container q , which is covered with a sheet metal dome so that it can be lifted off, is slipped onto the tube η ; the tube η passes through the sieve-like perforated bottom s of the same in the middle. On the bottom s there is an insert, which consists of the ring r (the latter made of galvanized brass wire), which is covered with canvas and provided with wire handles for lifting, and is used for straining the coffee grounds wetted by the hot water from η. A cheesecloth made of parchent is stretched over the perforated floor underneath in the middle of the tire t which has been stripped onto the edge of q outside.

By the so-constructed bottom of the fully cooked and filtrirte coffee reaches m in the container and is supported by the underlying furnace remains hot.

The coffee level is indicated by the marked glass χ . The coffee itself is drained through the tap υ , while the hot water for the purpose of making tea, grog, etc., can be drained off through the tap u.

The tap w is used to completely drain the water in the boiler g.

On one side of the lower part there is a tabletop at a corresponding height Wood attached.

The upper kettle / contains about 10 liters and the coffee container m 8 liters, so that there is always an excess of 2 liters of water in the former to prevent the bottom of the kettle from melting.

The heating is best done with charcoal, and both firings require 0.05 hl of coal per hour. It takes about 40 minutes to heat the water in the kettle g until it boils, while it takes about 8 minutes to brew the coffee, including pouring in the flour, and to clean the sieves.
