Dear Kevin, Marc, Crispin and all,
I hope my rough and ready translation (link to the Original text below) will be exact enough. Those patent/law formulations are somehow twisted (the other possible translation of verdreht would be crazy :-) ) and difficult to understand even in the native language If there is some doubt to be right, or lack of understanding, use the very good dictionary <http://dict.leo.org/ende?lang=de&lp=ende> LEO Deutsch-Englisches Wörterbuch -Which I am often forced to use to understand English texts, even from the stoves-list; but worse the multiple-sensed abbreviations. Fritz Kaftanski Koeln am Rhein (Germany) Sawdust stove with insert-firing Patented in Germany beginning from November 28th 1922 Object of the invention is a saw-dust stove with insert-firing in order to burn saw-dust an piece/lump (sized) fuel as Coal, wood and so on. It is possible to use the insert-firing in already existing saw-dust-stoves, without outer changing of the stove, as e.g. mounting fire- or ash-doors and so on. Those stoves for burning saw-dust are composed mainly (as shown in Fig Abb3 ) out of a mantle, a cylindrical insert, which serves as fuel container, and the essential part (e), with its help the centre burning channel is created.. As there is lack of saw-dust or similar fuel, it is not possible to run such a stove with coal or other piece-shaped fuel, because there is no griddle, und especially, because saw-dust stoves have neither firing nor ash-doors. Following the invention there is the possibility to run the saw-dust-stove, as desired with flour-shaped and piece-shaped fuel and to run a saw-dust-stove by use of the insert-firing without essential change into a coal-stove.. Fig 1 Saw-dust-stove with insert-firing, view from above Abb 2 insert-stove in vertical cut from the side Abb.3 saw-dust-stove with inbuilt insert-firing in cross-section The insert-firing consists mainly out of the housing d11 wit side hooking-edges. In the housing is the basket-griddle a . It is with sufficient distance from the wall of the housing d11 respectively d1 in that hooked, so that kindling can be brought in. The housing d11 is at same time fire-starting-basket and ash-basket and it has a door for regulating the air-administration. In the bottom there is opening for ash removing containing an closing-clap c. This opening serves as well as duct for the heat-gas into the stove, when the basket is used as stove/burning-chamber. When used as saw-dust-stove it serves as centre-piece c as insert-opening. By the position of the griddle-basket is it possible to start the fire from top, without a stove-starting-door at the side. By this manner of starting the fire, the fire burns from down (von unten) to top (nach oben). Before placing the inset-firing it is possible to place paper. To start the fire, it is sufficient to light the paper from above. The rest text is about rights for the patent. I dont know if there are still rights on that, but now after 85 years I guess that is history. Thats so far the translation. Marc, you can have a look to the DEOM-stove (http://www.deomturbo.com/fonctionnement-poele-luxembourg.asp ) made in Belgium and France, which can burn as well saw-dust. This type of stove is sold in Great Britain as well. Look at: http://www.relaxstoves.co.uk/ The difference between both is the exit of the flue-pipe. The British has on top, the DEOM has rear. I know, there are different needs for the chimney-length between both and I think this is because of that different flue-gas-outlet. Possibly you are interested, to know that this type of stove is as well built as a cooking stove with baking-oven. Look at: http://www.deomturbo.com/cuisiniere-feu-bois-luxembourg.asp Crispin, thanks for your general comments about old stoves/inventions and their alterations. It is the same the line I am thinking, naturally without your profound knowledge. Regards Martin P.S.

Let the stovers know if you would like to modernize it for whatever purpose. Best wishes for the New Year! Regards Martin
