This stove is now in my collection Emil Otto in Magdeburg was granted a patent in 1889 for this stove. Best Regards, Magnus Thilander
Hello Magnus, What a beautiful stove! I have long thought that yours is the most perfect name for a stove collector "Mag" as in magnet with "us" as a common suffix, of sorts, for Prim-us, Optim-us, Radi-us, etc. and now one I had never heard of; Spiritus. It's like you are a born stove-magnet. Best.. Gary
Spiritus = spirit, alcohol, meths. The Germans call alcohol stoves Spiritus Kocher. More a description off the type of stove than it's name. I'm guessing it will be an Emil Otto spiritus kocher but it's not always the patent holder who makes & gives their name to the stove. Certainly an unusual model Magnus has showed us before in the Stove Forum. Magnus - did you figure out what the tap was for?
Thanks - I thought there was more text. That's 3 places they put the patent number! maybe if someone can translate the patent we will know how this strange beast works? Link
Ross, the PDF-file behind this link is partly broken. I can read only the first page, unfortunuately I don't see the drawings. So translation is a little difficult. Anyway, here is the text of the description, the claim says nothing different about function of the stove. I hope, it will be understandable at all. @Magnus: Congratulation to that find! Imperial Patent Office Patent Specification - No. 49510 - Class 34: Household appliances Emil Otto in Magdeburg Spirits-stove (cooking-device). Patented in German Empire from 28th of March 1889 on. The spirits intended for burning are kept in the as closely as possible locked container a. If necessary one opens the valve b, by which the spirits flow into the area c, whose walls are surrounded with a cotton wick. If the spirits are ignited, the flame strikes up by the opening between ii, the more productively, the further mobile piston h goes downward, which is mobile by the gear wheel g. If the liquid which is cooked reaches the boiling point, then an importantly smaller flame is sufficient, in order to receive this point of heat. This is reached by winding up the piston h. The more the piston h approaches the opening ii, the smaller the flame becomes; it dissappears, if the opening ii is closed completely. Also the valve d opens at the same time, which is mobile by the spring e pressed in slightly and in the hinge f, as the fork k tightens the end of the valve lever. The spirits remaining in the heating space c leaves to l, flows over the diagonally attached soil m to n and arrives by this opening into the cold area o, whereby evaporating of the spirits is prevented. Later the remaining spirits can be discharged by the cock p and be back-poured into the container a again. Kind regards, Christian
